Abstract Purpose To present our experience and provide a literature review dissertation about the use of a suture-mediated percutaneous closure device (Perclose Proglide -PP- Abbott Vascular Inc., Santa Clara, CA, USA) to achieve hemostasis for unintended subclavian arterial catheterization during central venous line placement. Materials & methods Since October 2020, we have successfully treated four consecutive patients with a central venous catheter (8 to 12 French) in the subclavian artery. In each patient, we released a PP, monitoring its efficacy by performing a subclavian angiogram and placing, as a rescue strategy, an 8 mm balloon catheter near the entry point of the misplaced catheter. Primary outcome is technical and clinical success. Technical success is defined as absence of bleeding signs at completion angiography, while clinical success is a composite endpoint defined as absence of hematoma, hemoglobin loss at 12 and 24 h, and absence of procedure-related reintervention (due to vessel stenosis, pseudoaneurysm or distal embolization). Results Technical success was obtained in 75% of cases. In one patient a mild extravasation was resolved after 3 min of balloon catheter inflation. No early complications were observed for all patients. Conclusions PP showed a safe and effective therapeutic option in case of unintentional arterial cannulation. It can be considered as first-line strategy, as it does not preclude the possibility to use other endovascular approaches in case of vascular closure device failure.

Introduction: Management of subclavian artery injuries (SAI) and iliac artery injuries (IAI) in adolescent trauma patients poses a considerable challenge due to their complex anatomical locations. The aim of our study was to determine the association between the injury mechanism and type of repair with the outcomes of patients with traumatic SAI and IAI., Methods: In this retrospective analysis of the American College of Surgeons Trauma Quality Improvement Program database2017-2020, adolescent (<18 y) patients with SAI and IAI undergoing either endovascular or open repair were included. Patients were stratified by mechanism (blunt versus penetrating) and type of repair (endovascular [E] versus open [O]) and compared. Outcomes measured were mortality and major complications. Multivariable logistic regression analyses were performed., Results: Over 4 y, 170 pediatric patients were identified, of which 73 (43%) sustained an SAI and 97 (57%) had IAI. The mean age was 15 and 79% were male. Overall, 39% were managed endovascularly. Both groups had comparable median injury severity score (E: 23 versus O: 25, P = 0.278). For patients with blunt injury (n = 60), the type of repair was neither associated with major complications (E: 39% versus O: 33%, P = 0.694) nor mortality (E: 2.6% versus O: 4.8%, P = 0.651). For patients with penetrating injuries (n = 110), the endovascular repair had significantly lower morbidity (19% versus 41%, P = 0.034) and mortality (3.7% versus 21%, P = 0.041). On multivariable logistic regression, endovascular repair was identified as the only modifiable risk factor associated with reduced mortality (adjusted odds ratio: 0.201, 95% confidence interval [0.14-0.76], P = 0.038)., Conclusions: Difficult-to-access vascular injuries result in significant morbidity and mortality. Endovascular repair was found to be the only modifiable factor associated with decreased mortality of patients with penetrating injury, whereas the type of repair was not associated with mortality in those with blunt injury., (Copyright © 2024 Elsevier Inc.

Objective: Traumatic axillary and subclavian artery injuries are uncommon. Limited data are available regarding patient and injury characteristics, as well as management strategies and outcomes., Methods: Retrospective chart review was performed on patients presenting to University of Louisville Hospital, an urban Level One Trauma Center, with traumatic axillary and subclavian artery injuries from 2015-2021. Patients were identified using University of Louisville trauma, radiology, and billing database searches based on ICD9/10 codes for axillary and subclavian artery injuries. Descriptive statistics are expressed as frequencies and percentages. Comparisons were performed using Fisher's Exact and Chi-squared tests., Results: Forty-four patients with traumatic axillary-subclavian arterial injuries were identified for analysis. Blunt and penetrating trauma were equally represented (n = 22 for both). A variety of injury types were seen, including minimal/intimal injury, laceration, pseudoaneurysm, transection, occlusion, and arteriovenous fistula. Management strategies were also variable, including non-operative, endovascular, planned hybrid, open, and endovascular converted to open. In operative patients, revascularization technical success was high (n = 31, 97%) with low likelihood of thrombosis (n = 2, 6%) and no infections. Among all patients, amputation rate was 5% (n = 2) and mortality rate was 9% (n = 3). Regarding arterial involvement, blunt injury was more likely to affect the subclavian (n = 18) than the axillary artery (n = 6) ( P = .04). No significant difference was seen in brachial plexus injury based on artery involved (subclavian = 9 vs axillary = 11, P = .14) or mechanism (blunt = 6 vs penetrating = 11, P = .22). Non-operative management was more likely with subclavian artery injury (n = 11) vs axillary artery injury (n = 1) ( P = .008). There was no significant difference between decision for non-operative (blunt = 9, penetrating = 3) vs operative (blunt = 13, penetrating = 19) management based on mechanism ( P = .09). Transection injury was associated with an open repair strategy (endovascular/hybrid = 1, open/endovascular to open conversion = 11, P = .0003). Of the three patients requiring endovascular to open conversion, two required amputation, which were the only two patients in the study undergoing amputation., Conclusions: Both open and endovascular/hybrid strategies are useful when treating traumatic axillary and subclavian artery injuries and are associated with high likelihood of revascularization technical success, with low rates of thrombosis or infection, when treated promptly at a trauma center with vascular specialists available. Transection injuries were most often treated with open revascularization. Patients undergoing amputation had blunt transection injuries to the subclavian artery and underwent endovascular to open conversion after failed attempts at endovascular revascularization., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Rationale: Subclavian arterial injury due to blunt trauma is rare but can have devastating outcomes. Massive hemorrhage or limb ischemia might develop depending on the extent of damage, and open repair might be necessary to salvage the limb. However, life-saving treatments should be prioritized in critically unstable patients., Patient Concerns: A 21-year-old male patient who was transferred to our trauma center following a motorcycle accident. Abdominal and chest computed tomography (CT) revealed right renal injury and massive hemothorax with several rib fractures in the right chest., Diagnosis and Interventions: Right renal injury with multiple extravasations and right 8th intercostal arterial injury were detected during angiography. Emergent exploration with lateral thoracotomy was performed to manage right hemothorax. Pulsating bleeding from the thoracic roof observed in the operative field suggested a subclavian arterial injury. The unstable vital signs did not recover despite massive transfusion, and his right arm had already stiffened. Therefore, endovascular approach was adopted and the second portion of the right subclavian artery was embolized using microcoils and thrombin., Outcomes: Postoperative intensive care unit management performed to resuscitate patient from multiorgan failure included continuous renal replacement therapy (CRRT). After confirming the demarcation lines, transhumeral amputation of the right arm was performed on admission day 12. The patient recovered from multiorgan failure for more than 3 weeks after the accident; however, the patient survived., Lessons: Limb salvage, albeit critical for quality of life, is not possible in some cases where life-saving measures require its sacrifice. In these cases, quick decision-making by the surgeon is paramount for patient survival. As illustrated in this case, endovascular approaches should be considered less invasive measures to save the patient's life., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Rationale: Subclavian artery (SCA) injuries, though rare, carry significant morbidity and mortality risks due to significant blood loss causing hypovolemic shock. Early diagnosis and adequate treatment are crucial to minimize bleeding and associated morbidity. Recent advances in endovascular techniques offer faster and more accurate treatment options compared to traditional open surgical repair. This study demonstrates the efficacy of endovascular treatment in 2 cases of SCA injury and reviews its indications, limitations, and precautions., Patient Concerns: A 69-year-old man presented with a penetrating SCA injury from a steel bar, and a 38-year-old woman presented with a blunt SCA injury caused by a fall. Both patients were hemodynamically unstable upon presentation., Diagnoses: Both patients were diagnosed with SCA injuries. The man had a penetrating injury, while the woman had a blunt injury, both resulting in hemodynamic instability and significant risk of hypovolemic shock., Interventions: Endovascular techniques, including the use of covered stent grafts, were employed to manage the injuries. These techniques allowed for rapid and efficient treatment, reducing the need for open surgical intervention., Outcomes: Both patients were successfully treated using endovascular methods and were discharged without any complications. The endovascular approach minimized blood loss, transfusion needs, and hospital stay., Lessons: This study demonstrates the effectiveness of endovascular techniques in rapidly diagnosing, bridging, and definitively treating SCA injuries, suggesting their use as a first-line therapy., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Subclavian artery injury during central venous line placement is a potentially life-threatening complication. Due to historically high mortality rates with attempted manual pressure for haemostasis, the current favoured method of repair is by open or endovascular means. This case describes the management of a central venous catheter placed through the internal jugular vein into the subclavian artery via a supraclavicular puncture. CT angiography revealed the arterial injury located 1 cm distal to the vertebral artery origin. Under fluoroscopic guidance in an endovascular hybrid theatre, a covered stent was deployed across the affected segment of the subclavian artery which resulted in occlusion of the vertebral artery origin to attain safe proximal seal. This was done during simultaneous removal of the catheter and manual pressure over the internal jugular vein. There were no complications and the patient recovered well post-procedure. This case highlights the importance of appropriate ultrasound techniques for central catheter insertion for precise visualisation to prevent inadvertent injury to distal structures. CT angiography is useful in planning endovascular management. Occlusion of the vertebral artery in this case did not result in any neurological complications., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objectives: Inadvertent subclavian artery cannulation during attempted subclavian central venous access is more likely to occur during rushed trauma resuscitations when anatomic landmarks are used for placement. Traditional supraclavicular and infraclavicular approaches for direct repair of the resultant arteriotomy are painful, morbid procedures that should be replaced with more minimally invasive techniques., Methods: This case report describes the usage of a percutaneous suture-mediated device (Perclose Proglide, Abbott Laboratories) to repair an iatrogenic subclavian artery arteriotomy., Results: Two patients had their injuries successfully repaired using a percutaneous closure device., Conclusions: The use of a percutaneous closure device to repair iatrogenic subclavian artery injuries is a safe and effective method of repair that precludes a more invasive exposure and repair.

Subclavian artery injuries are sporadic, and the most common aetiology is trauma. Self-injury of the vessel in those misusing intravenous drugs is a rare complication, as most reports describe injury to the femoral artery. Thus, erosion and potential rupture of the arterial wall is possible due infection and phlegmon or abscess formation. We present a case of a young, female, hemodynamically unstable intravenous drug user admitted to the emergency department with a life-threatening, purulent haemorrhagic mass located at her right lateral cervical region. The patient admitted an inadvertent arterial puncture 10 days prior and an effort to self-manage the bleeding with the application of self-pressure and antibiotics. Computed tomography arteriogram of the neck revealed a gigantic, multicompartment, thick-walled collection with hyperdense fluid in her right supraclavicular region while active extravasation derived from the right subclavian artery was evident in late arterial phase. The patient was treated with endovascular graft stenting, despite the given presence of infection, as a salvage operation due to time limitation in open surgical repair., (© Royal College of Physicians 2023.

The management of a rare midclavicular crossbow bolt injury to the subclavian artery is discussed. Important concepts include the initial clinical diagnosis, operative planning, the surgical approach to the retro-clavicular great vessels, the technical aspects of repair, and postoperative course. A discussion of the reasoning behind an operative vs. endovascular approach is also discussed.

Background: Elective Thoracic Endovascular Aortic Repair (TEVAR) with left subclavian artery coverage (LSA-C) without revascularization is associated with increased rates of ischemic stroke. In patients with blunt thoracic aortic injury (BTAI) requiring TEVAR, LSA-C is frequently required in over one-third of patients. This study aimed to evaluate outcomes of TEVAR in BTAI patients with and without LSA-C., Methods: The largest existing international multicenter prospective registry of BTAI, developed and implemented by the Aortic Trauma Foundation, was utilized to evaluate all BTAI patients undergoing TEVAR from March 2016 to January 2021. Patients with uncovered left subclavian artery (LSA-U) were compared with patients who had left subclavian artery coverage with (LSA-R) and without (LSA-NR) revascularization., Results: Of the 364 patients with BTAI who underwent TEVAR, 97 (26.6%) underwent LSA-C without revascularization, 10 (2.7%) underwent LSA-C with revascularization (LSA-R). Late and all ischemic strokes were more common in LSA-NR patients than LSA-U patients ( p = 0.006, p = 0.0007). There was no difference in rate of early, late, or overall incidence of paralysis/paraplegia between LSA-NR and LSA-U. When compiled as composite central nervous system ischemic sequelae, there was an increased rate in early, late, and overall events in LSA-NR compared with LSA-U ( p = 0.04, p = 0.01, p = 0.001)., Conclusion: While prior studies have suggested the relative safety of LSA-C in BTAI, preliminary multicenter prospective data suggests there is a significant increase in ischemic events when the left subclavian artery is covered and not revascularized. Additional prospective study and more highly powered analysis is necessary., Level of Evidence: Therapeutic/Care Management; Level III., (Copyright © 2022 American Association for the Surgery of Trauma.)

Traumatic injuries of the subclavian and axillary arteries are uncommon but have high morbidity and mortality. In contrast to penetrating injuries, which are often lethal, blunt injuries present a wide and heterogeneous spectrum of imaging findings. If a vessel tear or transsection is a life-threatening circumstance, minor injuries might be overlooked in an emergency setting but could cause or aggravate the functional loss of a limb. The aim of this pictorial essay is to acquaint radiologists with the spectrum of imaging findings that could be encountered during the radiological evaluation of the subclavian/axillary artery (SAA) in trauma patients and offer tips and tricks to improve the diagnostic workup of patients with suspected blunt SAA injuries.

Background: Thoracic endovascular repair has become the standard treatment for blunt thoracic aortic injury (BTAI). Occlusion of the left subclavian artery (LSA) is generally required for an adequate landing zone (ALZ). We propose that coverage of the LSA is not necessary for BTAI even with a short landing zone (SLZ)., Methods: Retrospective review of BTAI patients, who were treated from January 2008 to December 2020, was analyzed. BTAI was categorized into 2 cohorts, SLZ <20 mm and ALZ >20 mm. Demographic data, trauma scores, grade of BTAI, procedure-related data, and clinical outcomes were analyzed. t-Test and chi-squared tests were used for statistical analysis., Results: Thoracic endovascular repair was performed in 59 BTAI patients (mean age of 38.9 ± 14 years, mean Injury Severity Score of 40.4 ± 9.3). Two cohorts were identified: 49 patients had an SLZ, and 10 patients had an ALZ (14 ± 3.1 mm vs. 25 ± 4.1 mm, P = 0.03). The procedures were performed successfully with 59 patients (86.4%) deploying in zone 3. In-hospital mortality (SLZ group: 4.1% vs. ALZ group: 0, P = 0.318), endoleak (SLZ group: 4.1% vs. ALZ group: 20%, P = 0.45), stroke (SLZ group: 0 vs. ALZ group: 0, P = 1), spinal cord ischemia (SLZ group: 2% vs. ALZ group: 0, P = 1), left arm ischemia (SLZ group: 0 vs. ALZ group: 0, P =1), and reintervention rate (SLZ group: 0 vs. ALZ group: 0, P = 1) were not statistically different between cohorts., Conclusions: BTAI repair with an SLZ can be treated successfully without covering the LSA, analyzing technical success and in-hospital complications. Mid- and long-term data are necessary to confirm the durability of this technique., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Abstract: Objectives: The surgical management and outcome of penetrating subclavian artery (SCA) injuries is presented in this article. Design: A retrospective chart review is used to detail the management and outcome of penetrating SCA injuries. Patients and methods: Patients with penetrating SCA injuries presenting to the Groote Schuur Hospital from January 1997 to December 2007 were reviewed. Demographic data, mechanism of injury, associated injuries, angiographic findings, surgical treatment, hospital stay, complications and mortality were noted. Results: Fifty patients with penetrating SCA injuries were identified from an operating trauma database. Stab and gunshot wounds accounted for 40 and 10 SCA injuries, respectively. The mean Revised Trauma Score (RTS) was 7.2. Angiography was obtained in 37 patients; false aneurysm (13) and total occlusion (nine) were the two most common findings. A median sternotomy was required in 25 (50%) patients and emergency room thoracotomy was performed in two patients (4%) for initial haemorrhage control. Primary repair of SCA injuries was possible in 52% of the patients. Three SCA injuries (6%) were ligated and one patient received an endovascular stent. Morbidity was restricted to associated brachial plexus injuries. The limb salvage rate was 100% and there were no deaths. Conclusion: Preoperative angiography was useful in planning an operative approach. Primary repair was possible in the majority of the patients and ligation of SCA injuries was life-saving in critically ill patients. [Copyright &y& Elsevier]

Abstract: Objective: This study aims to describe the clinical management of inadvertent arterial catheterisation after attempted central venous catheterisation. Methods: Patients referred for surgical or endovascular management for inadvertent arterial catheterisation during a 5-year period were identified from an endovascular database, providing prospective information on techniques and outcome. The corresponding patient records and radiographic reports were analysed retrospectively. Results: Eleven inadvertent arterial (four common carotid, six subclavian and one femoral) catheterisations had been carried out in 10 patients. Risk factors were obesity (n =2), short neck (n =1) and emergency procedure (n =4). All central venous access procedures but one had been made using external landmark techniques. The techniques used were stent-graft placement (n =6), percutaneous suture device (n =2), external compression after angiography (n =1), balloon occlusion and open repair (n =1) and open repair after failure of percutaneous suture device (n =1). There were no procedure-related complications within a median follow-up period of 16 months. Conclusions: Inadvertent arterial catheterisation during central venous cannulation is associated with obesity, emergency puncture and lack of ultrasonic guidance and should be suspected on retrograde/pulsatile catheter flow or local haematoma. If arterial catheterisation is recognised, the catheter should be left in place and the patient be referred for percutaneous/endovascular or surgical management. [Copyright &y& Elsevier]

A man in his 60s was referred for urgent coronary artery bypass grafting (CABG) procedure following acute coronary syndrome. After induction of general anaesthesia, right jugular venous catheterisation under two-dimensional ultrasound guidance was planned as part of perioperative management. While obtaining vascular access, the pulsatile flow was noted once the dilator was inserted, having to abandon the procedure and immediately apply manual pressure. CT angiogram showed proximal right subclavian artery injury with active contrast extravasation and resultant large haematoma in the neck. The patient underwent urgent exploration of the injured vessel through a J-shaped ministernotomy, and primary repair of the artery was performed. The patient recovered from the procedure without any complications. He continued to stay in the hospital for a few days, afterwards, he underwent the initially planned CABG surgery. He was discharged home on day 5 after surgery without further concerns., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2022. No commercial re-use.

Background: Traumatic subclavian artery injury (SAI) remains uncommon but can lead to significant morbidity and mortality. Although open and endovascular repair offer excellent limb salvage rates, their role in blunt and penetrating injuries is not well defined. The goal of this study was to examine the effect of mechanism of injury and type of repair on outcomes in patients with traumatic SAI., Study Design: Patients undergoing procedures for traumatic SAI were identified from the Trauma Quality Improvement Program database between 2015 and 2018. Demographics, severity of injury and shock, type of subclavian repair (open vs endovascular), morbidity, and mortality were recorded. Patients with SAI were stratified by mechanism and type of repair and compared. Multivariable logistic regression (MLR) analysis was performed to determine independent predictors of mortality., Results: Seven hundred thirty-seven patients undergoing procedures for SAI were identified. Of these, 39% were penetrating. The majority were male (80%) with a median age and Injury Severity Score (ISS) of 37 and 21, respectively. 58% of patients were managed endovascularly. For patients with blunt injury, the type of repair affected neither morbidity (25% vs 19%, p = 0.116) nor mortality (11% vs 10%, p = 0.70). For patients with penetrating injuries, endovascular repair had significantly lower morbidity (12% vs 22%, p = 0.028) and mortality (6% vs 21%, p = 0.001). MLR identified endovascular repair as the only modifiable risk factor associated with reduced mortality (odds ratio, 0.35; 95% confidence interval, 0.14 to 0.87, p = 0.02)., Conclusions: SAI results in significant morbidity and mortality regardless of mechanism. Although the type of repair did not affect mortality in patients with blunt injury, endovascular repair was identified as the only modifiable predictor of reduced mortality in patients with penetrating injuries., (Copyright © 2022 by the American College of Surgeons.

Background: In traumatic axillo-subclavian vessel injuries, endovascular repair has been increasingly described, despite ongoing questions regarding infection risk and long-term durability. We sought to compare the clinical and safety outcomes between endovascular and surgical treatment of traumatic axillo-subclavian vessel injuries., Method: A search query of the prospectively maintained PROOVIT registry for patients older than 18 years of age with a diagnosis of axillary or subclavian vessel injury between 2014-2019 was performed at a Level 1 Trauma Center. Patient demographics, severity of injury, Mangled Extremity Severity Score (MESS), Injury Severity Score (ISS), procedural interventions, complications, and patency outcomes were collected and analyzed., Results: Twenty-three patients with traumatic axillo-subclavian vessel injuries were included. There were similar rates of penetrating and blunt injuries (48% vs. 52%, respectively). Eighteen patients (78%) underwent intervention: 11 underwent endovascular stenting or diagnostic angiography; 7 underwent open surgical repair. There was similar severity of arterial injuries between the endovascular and open surgical groups: transection (30% vs. 40%, respectively), occlusion (30% vs. 40%, respectively). The open surgical group had worse initial clinical comorbidities: higher ISS scores (17.0 vs 13.5, p = 0.034), higher median MESS scores (6 vs. 3.5, P = 0.001). The technical success for the endovascular group was 100%. The endovascular group had a lower estimated procedural blood loss (27.5 mL vs. 624 mL, P = 0.03). The endovascular arterial group trended toward a shorter length of hospital stay (5.6 days vs. 27.6 days, P = 0.09) and slightly reduced procedural time (191.0 min vs. 223.5 min, P = 0.165). Regarding imaging follow up (average of 60 days post-discharge), 7 patients (54%) underwent surveillance imaging (5 with duplex ultrasound, 2 with computed tomography angiography CTA) that demonstrated 100% patency. Regardless of ISS or MESS scores, at long term clinical follow up (average of 214 days), there were no limb losses, graft infections or vascular complications in either the endovascular or open surgical group., Conclusions: Endovascular treatment is a viable option for axillo-subclavian vessel injuries. Preliminary results demonstrate that endovascular treatment, when compared to open surgical repair, can have similar rates of technical success and long-term outcomes in patency, infection and vascular complications., (Published by Elsevier Inc.)

Subclavian and proximal axillary arterial injuries are rare and difficult to manage. Eight patients were managed from January 2008 to December 2018 at The Aga Khan University Hospital, Karachi, Pakistan with mean age of 36.13 ± 14.48 years. All patients had penetrating injuries, from gunshot in 5 (62.5%), bomb blast in 2 (25%), and stab wound in 1 (12.5%) case. Six (75%) patients presented in haemodynamically stable condition. The mean time between the injury and patient presentation was 28 ± 8.39 hours. The injuries were approached via supraclavicular incision in 3 (37.5%) patients, infraclavicular incisions in 2 (25%) patients and median sternotomy in 2 (25%) patients. Three (37.5%) patients had false aneurysm, while 5 (62.5%) had transected artery. Primary repair was performed in 2 (25%) cases, while 6 (75%) patients were treated with interposition graft with polytetrafluoroethylene (PTFE). All patients have salvaged limbs with good functional outcomes.  Key Words: Subclavian artery, Penetrating injury, Vascular trauma, Vascular repair.

Penetrating injuries to the subclavian artery carry a high mortality rate, especially when the patient presents in shock. Rapid and effective haemorrhage control is challenging due to the anatomical location at the thoracic outlet. Historically, vessel ligation has been used to control bleeding, but this is often performed late, when metabolic exhaustion is established, and is associated with upper-limb ischaemia and limb loss. Rapid proximal control through the chest with temporary intravascular shunting is the damage control technique of choice to temporise blood loss and restore perfusion until the patient is physiologically optimised for a delayed definitive vascular repair. We describe a case of vascular damage control in a patient after gunshot wound.

Background: Traumatic subclavian artery injuries are associated with high morbidity and mortality. Thoracic cage and clavicle provide a well protection of the underlying subclavian vessels and nerves and also cause a very limited operation space during open surgery. The endovascular modality is less invasive and alternative to conventional open surgical reconstruction., Purpose: The purpose of this study was to analyze the different therapeutic effects on limb salvage., Methods: A retrospective review of patients who presented with blunt or penetrating injuries to the subclavian arteries between March 2012 and March 2021., Results: Endovascular and open repairs were both effective for traumatic subclavian artery injury. There was no statistical difference in the limb salvage, mortality, procedure-related complication, reintervention rate and in-hospital medical complications. Intraoperative blood loss, red blood cell transfusion requirement and length of hospital stay were significantly lower in the endovascular intervention group., Conclusion: Endovascular treatment represents an attractive alternative to the traditional surgical approach for the treatment of traumatic injuries in the subclavian., Competing Interests: The authors declare that they have no conflicts of interest in this work., (© 2021 Tanmit et al.)

Objective: Subclavian artery aneurysms (SAAs) are uncommon but life-threatening, and a standard treatment approach has yet to be established. The current study aimed to assess the safety and efficacy of endovascular treatment for SAAs., Methods: The clinical data of 18 SAA patients who underwent endovascular repair at 3 hospitals from January 2009 to December 2019 were retrospectively collected and analyzed., Results: Eighteen patients (12 men and 6 women) with a mean age of 61 years were included. Six patients (33.3%) had a history of hypertension, and 5 (27.8%) had a history of chest trauma. Five patients (27.8%) were asymptomatic. Thirteen (72.2%) SAAs were true aneurysms, and the others (27.8%) were posttraumatic false aneurysms. Endovascular stent graft repair was performed in all patients without conversion to open surgery. The immediate technique success rate was 94.4%, with no postoperative death and only one case (5.6%) of endoleak that was observed on intraoperative angiography and later resolved spontaneously. All patients survived over a median follow-up time of 57 months. Follow-up imaging showed that all stent grafts remained patent, with no endoleak., Conclusions: Endovascular stent graft repair is feasible, safe, and effective for true and posttraumatic false SAAs and represents a promising treatment option for these SAAs., (Copyright © 2021.

Subclavian artery injury is a rare complication of clavicle fracture. The fractured clavicle can lacerate the underlying subclavian artery. Life-threatening haemorrhage can occur secondary to arterial laceration, and if distal blood flow is impaired, upper limb ischaemia can develop. There is little discussion in the literature regarding combined (or 'hybrid') endovascular and open surgical management of acute subclavian injuries secondary to clavicle fracture. We report a case of subclavian artery laceration secondary to clavicle fracture, managed with a combined endovascular and open surgical approach. An endovascular balloon was used for proximal arterial control, while surgical exposure and primary repair of the subclavian artery was completed, followed by fixation of the clavicle. There was no sustained vascular or neurological impairment at follow-up. We suggest that select traumatic injuries of the subclavian artery can be safely and successfully managed with a combined endovascular and open surgical approach., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021.

Background: A national analysis of clavicle fractures is lacking and the risk of concomitant axillosubclavian vessel injury (ASVI) in patients with clavicle fractures is unknown. A minority of patients may have a combined brachial plexus injury (BPI). We sought to describe risk factors for concomitant ASVI in patients with a clavicle fracture; hypothesizing patients with combined clavicle fracture and BPI has a higher risk of ASVI., Methods: The Trauma Quality Improvement Program (2010-2016) was queried for blunt trauma patients with a clavicle fracture. A multivariable logistic regression model was used to determine risk factors for ASVI. A subset analysis on patients with isolated clavicle fractures was additionally performed., Results: From 59 198 patients with clavicle fractures, 341 (.6%) had concomitant ASVI. Compared to patients without ASVI, patients with ASVI had a higher median injury severity score (24 vs. 17, P < .001) and rates of pulmonary contusions (43.4% vs. 37.7%, P = .029) and BPI (18.2% vs. .4%, P < .001). After controlling for associated chest wall injuries and humerus fracture, the BPI odds ratio (OR 49.17, 35.59-67.92, P < .001) was independently associated with risk for ASVI. In a subset analysis of isolated clavicle fractures, BPI remained associated with risk of ASVI (OR 60.01, confidence intervals 25.29-142.39, P < .001)., Conclusion: The rate of concomitant ASVI in patients with a clavicle fracture is <1%. Patients presenting with a clavicle fracture had a high rate of injuries including pulmonary contusion. Patients with findings suggestive of underlying BPI had a nearly 50 times increased associated risk of ASVI. Thus, a detailed physical exam in this setting including brachial-brachial index appears warranted.

Objective: Traumatic arteriovenous fistulas (AVFs) are rare. The vast majority occur secondary to penetrating injuries. High-output cardiac failure is a well-recognized serious complication of AVFs, associated with high morbidity and mortality. The objective of the present study was to identify predictors of heart failure (HF) in patients with traumatic AVF., Methods: Both PubMed/MEDLINE (Ovid) and CINAHL were searched (up to June 2019) for studies reporting individual patient data on the clinical and demographic characteristics of patients with AVF secondary to penetrating trauma. Exclusion criteria were age <18 years, no specification of symptoms, a cranial, spinal, or cardiac AVF location, and an iatrogenic mechanism of injury. The present study was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines., Results: A total of 274 AVF patients from 15 case series and 177 case reports were included. The median age at presentation was 32 years (interquartile range, 24-43 years), 90% were men. The most frequent mechanisms of injury were stab wounds (43%) and gunshot wounds (32%). The AVF location was the abdomen (n = 86; 31%), lower limb (n = 79; 29%), neck (n = 61; 22%), thorax (n = 38; 14%), and upper limb (n = 10; 4%). Of the 274 patients, 35 (13%) had presented with HF and 239 (87%) with other symptoms. The risk of HF increased with an increased feeding artery diameter (P < .001). On univariate analysis, HF was significantly associated with a longer median time from injury to presentation with AVF (11.2 years vs 0.1 years; P < .001), older median age at presentation (43 years vs 31 years; P = .002), involvement of a large feeding artery (ie, aorta, pulmonary artery, subclavian artery, external iliac artery; 40% vs 13%; P < .001), shrapnel injuries (11% vs 2%; P = .011), and injuries to the trunk or lower limb (94% vs 71%; P = .004). After adjusting for clinical and demographic patient characteristics, involvement of a large feeding artery (odds ratio, 3.25; 95% confidence interval, 1.26-8.42; P = .015) and every 6 years of delay to presentation (odds ratio, 1.30; 95% confidence interval, 1.03-1.63; P = .026) remained independent predictors for HF., Conclusions: HF occurs in a small but important fraction of traumatic AVF patients and develops after highly variable latency periods. Large feeding arteries and delayed presentation independently predicted HF in this cohort., (Copyright © 2020 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.)

Bicortical drilling of the clavicle is associated with risk of iatrogenic damage from plunging given the close proximity of neurovascular structures. This study determined plunge depth during superior-to-inferior clavicle drilling using a standard drill vs drill-sensing technology. Two orthopedic surgeons drilled 10 holes in a fresh cadaveric clavicle with drill-sensing technology in freehand mode (functions as standard orthopedic drill) and another 10 holes with drill-sensing technology in bicortical mode (drill motor stops when the second cortex is breached and depth is measured in real time). The drill-measured depths were compared with computed tomography-measured depths. Distances to the neurovascular structures were also measured. The surgeons' plunge depths were compared using an independent t test. With freehand (standard) drilling, the mean plunge depth was 8.8 mm. For surgeon 1, the range was 5.6 to 15.8 mm (mean, 10.9 mm). For surgeon 2, the range was 3.3 to 11.0 mm (mean, 6.4 mm). The surgeons' plunge depths were significantly different. In bicortical mode, the drill motor stopped when the second cortex was penetrated. Drill-measured depths were verified by computed tomography scan, with a mean difference of 0.8 mm. Mean distances from the clavicle to the neurovascular structures were 15.5 mm for the subclavian vein, 18.0 mm for the subclavian artery, and 8.0 mm for the brachial plexus. Plunge depths differed between surgeons. However, both surgeons' plunge depths were greater than distances to the neurovascular structures, indicating a risk of injury due to plunging. Although a nonspinning drill bit may still cause soft tissue damage, drill-sensing technology may decrease the risk of penetrating soft tissue structures due to plunging.

Introduction: Incidental arterial puncture is one of the main complications associated with central venous catheter placement. Manual compression to achieve hemostasis in subclavian and carotid artery punctures is often ineffective because of the anatomical arterial position. Accidental cannulation has traditionally been treated with open surgery or endovascular treatment, but such procedures are not exempt from complications., Objectives: Report our experience with ultrasound-guided off-label use of Perclose ProGlide (Abbott Vascular Inc., Santa Clara, CA, USA) in patients with iatrogenic arterial cannulation., Methods: Six unstable patients with accidental arterial catheterization during placement of a central venous catheter: five of them in the subclavian artery and one in the right common carotid artery. Ultrasound-guided percutaneous closure was performed at bedside using a Perclose ProGlide (Abbott Vascular Inc., Santa Clara, CA, USA)., Results: All patients underwent duplex ultrasound 6, 12, 24, and 48 h postprocedure, and no complications associated with percutaneous closure (embolism, ischemia, stenosis, or arterial occlusion, bleeding, pseudoaneurysm, etc.) were described., Conclusions: Accidental artery puncture during central venous catheterization is an uncommon situation but can be effectively managed by using percutaneous vascular closure device. It is a reliable alternative that should be considered as a first-line approach before endovascular or open surgery, specially in patients with unstable conditions in which it is possible to be performed without transfer to an operation room.

We present a rare case of a 10-cm right subclavian artery pseudoaneurysm, with slow growth over 4 years after a traumatic fracture of the right clavicle. The patient had multiple prior endovascular attempts of embolization and stenting at other hospitals; despite this the pseudoaneurysm continued to grow and caused mass effect and neurologic symptoms. We present our open approach for the repair and a review of literature.

Aim: To evaluate the safety and clinical efficacy of interventional treatment for arterial injury during blind, central venous catheterisation in the upper thorax at two tertiary medical centres., Materials and Methods: Eighteen consecutive patients (37-81 years; M:F=8:10) who underwent interventional treatment for the arterial injuries that occurred during central venous catheterisation without any imaging guidance between November 2007 and December 2018 were included. Clinical data, angiographic findings, detailed interventional procedures, and technical and clinical outcomes were analysed retrospectively., Results: Arterial injury sites were the subclavian artery/branches (n=12), axillary artery/branches (n=2), and common carotid artery (n=4). The target vein was not correlated with the corresponding artery/branches in eight patients (44.4%); internal jugular vein to subclavian artery branches. Angiographic findings were pseudoaneurysm (66.7%, 12/18), contrast medium extravasation (22.2%, 4/18), or both (11.1%, n=2). A stent graft was inserted for the main trunk injuries in nine patients, with (n=2) or without (n=7) prior arterial branch embolisation to prevent potential endoleak, while embolisation for the arterial branch injuries was performed in nine patients. Direct percutaneous access with thrombin injection to the pseudoaneurysm or residual arteriovenous fistula was utilised in two. The technical and clinical success rate was 94.4% (17/18) each. There were no procedure-related complications. In one patient without immediate clinical success, there was a persistent pseudoaneurysm after stent graft placement, which was treated with in-stent balloon dilation., Conclusion: Interventional treatment serves as a safe and effective treatment modality for inadvertent arterial injury related to blind, central venous access catheterisation in the upper thorax., (Copyright © 2019.

Purpose: To explore the significance of traditional vascular reconstruction and covered stent for limb salvage after subclavian artery injury., Methods: Patients with subclavian artery injury admitted to Beijing Jishuitan Hospital from January 2010 to December 2018 were retrospectively analyzed. All the injuries have been confirmed by intraoperative exploration, computed tomography angiography or digital subtraction angiography. Complete or partial amputation injuries were excluded. Mild artery defect or partial intimal damage was treated by interventional implantation, while other patients received open surgeries, including direct suture of small defect less than 2 cm and transplantation with autologous vein or artificial blood when the defect was more than 2 cm. Patients were divided into open surgery group and stent implantation group based on the treatment they received. Patients were followed up at 2 weeks (first stage) and 6 months (second stage) after operation to investigate limb salvage. Student's t-test was used to compare the general data between two groups and Chi-square test to analyze the rate of limb salvage., Results: Altogether 50 cases of subclavian artery injury were treated, including 36 cases of open surgery and 14 cases of stent implantation. Combination of nerve injury was observed in 27 cases (75.0%) in open surgery group and 12 cases (85.7%) in stent implantation group. Amputation developed in 3 cases with open surgery and 1 case with stent implantation. Consequently the rate of successful limb salvage was respectively 91.7% (33/36) and 92.9% (13/14), revealing no significant difference (p > 0.05)., Conclusion: Rapid reconstruction of blood circulation is crucial following subclavian artery injury, no matter what kinds of treatment strategies have been adopted. Interventional stent implantation can achieve a good effect for limb salvage., (Copyright © 2020. Production and hosting by Elsevier B.V.)

Purpose: Traumatic subclavian vascular injury (TSVI) is rare but often fatal. The precise diagnosis of TSVI remains challenging mainly because of its occult nature, less typical presentations, and being overlooked in the presence of polytrauma. Compared to penetrating injuries, it is even more difficult to identify TSVI in patients who have blunt injuries and no visible bleeding. The risk factors associated with TSVI in patients with thoracic trauma are unclear. The aims of this study were to identify risk factors for TSVI in a cohort of patients with thoracic vascular injuries and to report outcomes after clinical treatment., Methods: From January 2009 to June 2017, 39586 patients were admitted to our hospital (a level I trauma center) due to trauma, and 136 patients with thoracic vascular injury were enrolled in this study. We retrospectively reviewed data from medical records including demographic characteristics, injury scoring systems (RTS, ISS, NISS, TRISS and AIS), management and outcomes. Patients were further divided into the TSVI group (patients with TSVI) and the non-TSVI group (patients with thoracic vascular injuries other than TSVI). Univariate and multivariate analyses were used to identify independent risk factors., Results: The enrolled 136 patients suffered mostly from blunt trauma (89.0%) and 22 of them had TSVI. When compared to the non-TSVI group, the TSVI group had lower Glasgow Coma Scale (GCS) scores (p = 0.002; especially GCS ≤ 12), less concurrent abdominal injury (p < 0.001), lower Injury Severity Scales (ISS) (p = 0.007) and New Injury Severity Scales (NISS) (p < 0.002) but had higher Abbreviated Injury Scales (AIS) of the head ≥ 3 (p = 0.009) and rates of clavicular or scapular fractures (p = 0.013). No difference was detected between the two groups with regard to age, gender, trauma mechanism, vital signs on arrival, or rate of facial and extremities injury. In multivariate regression analyses, GCS ≤ 12, AIS of the head ≥ 3 and the presence of clavicular or scapular fractures were independent risk factors for TSVI (p = 0.026, p = 0.043 and p = 0.005, respectively) after adjustment for confounding factors. Open and endovascular repair were two surgical procedures utilized for these TSVI patients with an overall mortality rate of 18.2%. No difference was found between these groups with regard to mortality rate and the length of ICU stay, but the patients in the TSVI group had a shorter length of hospital stay., Conclusions: Our results suggest that GCS ≤ 12, AIS of the head ≥ 3 and the presence of clavicular or scapular fractures were independent risk factors for TSVI in patients with thoracic vascular injuries. For patients with thoracic trauma, TSVI should be considered for prompt management when patients exhibit concurrent injuries to the head, clavicle or scapula.

Martin Luther King Jr was the most prominent civil rights leader in the United States in the 1960s. He was shot by an assassin in Memphis, Tennessee, on April 4, 1968. After the shooting he was taken to a local hospital where he had an unsuccessful resuscitation for a right subclavian artery transection. Despite the fact that the circumstances around the assassination have been frequently reported and reviewed in the past 50 years, the specific vascular care of the traumatic injury has not been analyzed. This paper reviews the medical aspects of the King assassination and the management of his subclavian injury., (Copyright © 2019 Society for Vascular Surgery. All rights reserved.)

Objective: Axillosubclavian vessel injury is rare, with most cases occurring after penetrating trauma. A prior database (2002-2006) analysis demonstrated an overall limb loss rate of 2.9%, with no difference between isolated arterial axillosubclavian vessel injury and combined artery/vein axillosubclavian vessel injury. Given increases in advanced vascular surgical techniques, as well as improved multidisciplinary care and expeditious diagnosis with computed tomography angiography, we hypothesized the national rate of limb loss in patients with arterial axillosubclavian vessel injury has decreased. In addition, we attempted to identify current predictors for limb loss in arterial axillosubclavian vessel injury. Finally, we hypothesized that combined artery/vein axillosubclavian vessel injury, as well as associated brachial plexus injury will have a higher risk for limb-loss and mortality compared to isolated arterial axillosubclavian vessel injury., Methods: A retrospective analysis of the National Trauma Data Bank was performed between 2007 and 2015. All patients ≥ 18 years of age with arterial axillosubclavian vessel injury were included. The primary outcome was limb loss. After a univariable logistic regression model identified significant covariates, we performed a multivariable logistic regression for analysis., Results: Of the total 5,494,609 trauma admissions, 3807 patients had arterial axillosubclavian vessel injury (<0.1%). Of these, 3137 (82.4%) had isolated arterial axillosubclavian vessel injury and 670 (17.6%) had combined artery/vein axillosubclavian vessel injury. The overall limb loss rate was 2.4% (from 2.9% in 2006, p = 0.47). After adjusting for covariates, independent risk factors for limb loss included a combined artery/vein axillosubclavian vessel injury (odds ratio = 3.54, confidence interval = 2.06-6.11, p < 0.001), blunt mechanism (odds ratio = 7.81, confidence interval = 4.21-14.48, p < 0.001), open repair (odds ratio = 2.37, confidence interval = 1.47-3.82, p < 0.001), and open proximal humerus fracture (odds ratio = 8.50, confidence interval = 4.97-14.54, p < 0.001). An associated brachial plexus injury was not associated with limb loss ( p = 0.37). Combined artery/vein axillosubclavian vessel injury was associated with higher risk for mortality compared to isolated arterial axillosubclavian vessel injury (odds ratio = 2.17, confidence interval = 1.73-2.71, p < 0.001)., Conclusions: The national rate of limb loss in trauma patients with arterial axillosubclavian vessel injury has not changed in the past decade. A combined artery/vein axillosubclavian vessel injury is an independent risk factor for limb loss, as well as open repair. However, the strongest risk factor is an open proximal humerus fracture. An associated brachial plexus injury is not associated with increased risk of limb loss. Patients with combined artery/vein axillosubclavian vessel injury have a twofold increased risk of death compared to patients with isolated arterial axillosubclavian vessel injury.

Rationale: Transradial access (TRA) is a widely used technique during percutaneous coronary intervention (PCI). However, mediastinal and cervical hematomas, the rare and severe complications of transradial approach, have extremely high mortality rates. To the best of our knowledge, there were no medical literatures about the successful anticoagulation reversal procedure of mediastinal hematoma in PCI till now., Patient Concerns: We here present a 54-year-old male Han patient who underwent PCI. Immediately after PCI, he reported an episode of neck and chest discomfort, dyspnea, cough recurrence, and cold sweats. Emergency chest computed tomography (CT) revealed a perforation of the subclavian artery resulting in a large mediastinal hematoma with potentially lethal tracheal compression., Diagnosis: A diagnosis of the large mediastinal hematoma was made based on the enhanced computed tomography., Interventions: The patient was successfully managed with palliative therapy of anticoagulation reversal instead of a covered stent graft and surgical operation., Outcomes: Angiography confirmed the absence of leakage after anticoagulation reversal. The patient had an apparent remission of clinical dyspnea. Follow-up CT confirmed an almost entire absorption of the mediastinal hematoma 35 days postdischarge., Lessons: The current case highlights the importance of anticoagulation reversal as well as careful guidewire and guide catheter manipulation by the radial approach. Early evaluation, prompt identification, appropriate treatment, and close monitoring are all essential for invasive cardiology.

This is the first reported case of evidence of a hydrophilic wire traveling into a small branch and inducing perforation; this case highlights the need for fluoroscopically guided hydrophilic wire manipulation. Prompt treatment of such perforations is the best course of action.

Purpose: Clavicle fractures are common injuries in adults and children. Although neurovascular damage is rarely seen, acute subclavian artery pseudoaneurysms and injuries to subclavian vessels were reported for closed fractures of the clavicle. The aim of this study was to identify the morphological details of the subclavian vessels and their relation to the sternoclavicular joint and body of the clavicle., Methods: 127 patients (66 females and 61 males) were evaluated using reconstructed three-dimensional computed tomographic angiographies. The point at which the subclavian artery crossed posterior to the clavicle was detected as a landmark. The medio-lateral distance between the sternal end of the clavicle, landmark, antero-posterior distance between the clavicle and the subclavian artery, diameter of the artery and vein, angle between the subclavian artery and vein, distance of the subclavian vein to the subclavian artery and the clavicle at the landmark were measured. Measurements were compared according to gender and right and left sides, and age correlation was determined., Results: Morphometric relationship between the subclavian vessels and clavicle presented differences between genders. We measured the antero-posterior distance between the subclavian artery and the clavicle to be less than 1 cm (0.91 cm)., Conclusion: The subclavian artery travelled longer distances in men than women to reach the point that it crossed the clavicle. Our results demonstrated that the subclavian artery does not pass from the inferior margin of the clavicle, thus, superior plate osteosynthesis does not have any risk to injury against the subclavian vessels during the management of the clavicle fractures.

Background: Patients with stable blunt great vessel injury (GVI) can have poor outcomes if the injury is not identified early. With current pediatric trauma radiation reduction efforts, these injuries may be missed. As a known association between scapular fracture and GVI exists in adult blunt trauma patients, we examined whether that same association existed in pediatric blunt trauma patients., Methods: Bluntly injured patients younger than 18 years old were identified from 2012 to 2014 in the National Trauma Data Bank. Great vessel injury included all major thoracic vessels and carotid/jugular. Demographics of patients with and without scapular fracture were compared with descriptive statistics. The χ test was used to examine this association using SAS Version 9.4 (SAS Institute, Inc, Cary, NC)., Results: We found a significant association between pediatric scapular fracture and GVI. Of 291,632 children identified, 1,960 had scapular fractures. Children with scapular fracture were 10 times more likely to have GVI (1.2%) compared to those without (0.12%, p < 0.0001). Most common GVI seen were carotid artery, thoracic aorta, and brachiocephalic or subclavian artery or vein. Children with both scapular fracture and GVI were most commonly injured by motor vehicles (57% collision, 26% struck)., Conclusions: Injured children with blunt scapular fracture have a 10-fold greater risk of having a GVI when compared to children without scapular fracture. Presence of blunt traumatic scapular fracture should have appropriate index of suspicion for a significant GVI in pediatric trauma patients., Level of Evidence: Epidemiologic and prognostic study, level III; Therapeutic, level IV.

Aneurysms of the subclavian artery are rare phenomena that have the potential for limb and life-threatening complications. Delayed diagnosis increases the risk of life-threatening complications or at the very least may result in a detrimental effect to both functional capacity and quality of life; primary care offers a vital opportunity to screen for such rare vascular complications and should be a consideration in all patients with evolving peripheral nerve or vascular symptoms with a history of localized clavicular trauma. We present the case of a left subclavian artery aneurysm with radial artery thrombotic sequelae following an injury and screw-plate fixation of his left clavicle. This required a 2-stage surgical approach to treatment and provides useful learning considerations for identifying rare vascular anomalies early in a primary care setting.
