Purpose: Although blood loss in microsurgical reconstruction is rarely large enough to be life-threatening, preoperative anemia can be a particular issue in terms of postoperative morbidity, impaired wound healing, and compromised tissue viability. We seek to review the effect of preoperative hemoglobin (Hgb) levels on perioperative blood transfusion (PBT) requirements and complications to guide management of patients with preexisting anemia undergoing reconstruction., Methods: PubMed, Embase, and Scopus were queried for relevant articles. Inclusion criteria were as follows: original studies investigating outcomes and PBT requirements in flap-based reconstruction based on preoperative Hgb levels. Patient and study characteristics were analyzed using descriptive statistics. A meta-analysis was conducted to assess transfusion requirements across the included studies using Stata (version 18.0 Stata Corp, College Station, Texas, USA). The Fisher method was used to aggregate individual study p values into a single combined value to statistically assess the combined findings, where a p value of < 0.05 was set as statistically significant., Results: One thousand three hundred and eighty-nine studies were screened for title and abstract relevance, 14 of which met the inclusion criteria, including a total of 61,116 patients. Meta-analysis of the studies revealed a PBT requirement of 36.2% for anemic individuals, significantly higher than the 20.0% for those with normal preoperative Hgb levels (p < 0.001), with an average 4.9 versus 2.4 units of packed red blood cells being transfused (p < 0.001). The majority of studies concluded that preoperative anemia was associated with medical complications, such as myocardial infarction, stroke, and infection (p < 0.001). While six studies reported a significant relationship between low preoperative Hgb and flap morbidity (flap loss and partial flap necrosis), two studies found no correlation. The overall postoperative complication rate across the studies was 42.2% among patients with low preoperative Hgb levels, whereas the nonanemic group demonstrated a markedly lower rate of 13.9% (p < 0.001)., Conclusion: The existing evidence is strongly suggestive of increased PBT requirement in patients with anemia, highlighting the necessity for preoperative optimization of Hgb levels and intraoperative monitoring. While preliminary evidence demonstrates a relationship between anemia and medical complications, more research is warranted to characterize the specific association between preoperative Hgb levels and flap morbidity., (© 2024 Wiley Periodicals LLC.)

Background: Elevated body mass index (BMI) is a known perioperative risk factor for complications such as delayed wound healing and infection. However, there is a gap in understanding how elevated BMI impacts outcomes after posttraumatic lower extremity (LE) microvascular reconstruction., Methods: A retrospective review was performed at a level 1 trauma center between 2007 and 2022 of patients who underwent posttraumatic microvascular LE reconstruction. Demographics, flap/wound details, complications, and outcomes were recorded. Patients were stratified into BMI Center for Disease Control categories., Results: A total of 398 patients were included with an average BMI of 28.2 ± 5.8. Nearly half (45%) of LE defects were located in the distal third of the leg, 27.5% in the middle third, and 34.4% in the proximal third. Most reconstructions utilized muscle-containing flaps (74.4%) compared with fasciocutaneous flaps (16.8%). Surgical approaches included free flaps (47.6%) and local flaps (52.5%). Class III obese patients were significantly more likely to be nonambulatory than nonobese patients (OR: 4.10, 95% CI 1.10-15.2, p = 0.035). At final follow-up, 30.1% of patients with Class III obesity were ambulatory, requiring either wheelchairs (42.3%) or assistance devices (26.9%). There were no significant differences in complication rates based on obesity status (0.704). The average follow-up time for the entire cohort was 5.8 years., Conclusions: BMI is critical for patient care and surgical decision-making in LE reconstruction. Further research is warranted to optimize outcomes for higher BMI patients, thereby potentially reducing the burden of postoperative complications and enhancing overall patient recovery., (© 2024 Wiley Periodicals LLC.)

Background:  Free flaps are essential for limb salvage in patients with lower extremity (LE) trauma; however, significant donor-site morbidity could impact functional outcomes. This study compares postoperative ambulatory function between contralateral and ipsilateral free flap harvest in LE traumatic reconstruction., Methods:  A retrospective review was performed on patients who underwent LE reconstruction at a level 1 trauma center from 2009 to 2022. Flap characteristics, injury history, and ambulatory function were collected. Flap harvest laterality was determined in relation to the injured leg. The flaps were categorized as either fasciocutaneous or those that included a muscle component (muscle/myocutaneous). Chi-squared and Mann-Whitney tests were used for statistical analysis., Results:  Upon review, 173 LE free flaps were performed, of which 70 (65.4%) were harvested from the ipsilateral leg and 37 (34.6%) were from the contralateral leg. Among all LE free flaps, the limb salvage rate was 97.2%, and the flap survival rate was 94.4%. Full ambulation was achieved in 37 (52.9%) patients in the ipsilateral cohort and 18 (48.6%) in the contralateral cohort ( p  = 0.679). The average time to full ambulation did not vary between these cohorts ( p  = 0.071). However, upon subanalysis of the 61 muscle/myocutaneous flaps, the ipsilateral cohort had prolonged time to full ambulation (6.4 months, interquartile range [IQR]: 4.8-13.5) compared with the contralateral one (2.3 months, IQR: 2.3 [1.0-3.9]) p  = 0.007. There was no significant difference in time to full ambulation between flap harvest laterality cohorts among the fasciocutaneous flaps ( p  = 0.733)., Conclusion:  Among free flaps harvested from the ipsilateral leg, fasciocutaneous flaps were associated with faster recovery to full ambulation relative to muscle/myocutaneous flaps. Since harvesting muscle or myocutaneous flaps from the ipsilateral leg may be associated with a slower recovery of ambulation, surgeons may consider harvesting from a donor site on the contralateral leg if reconstruction requires a muscle component., Competing Interests: None declared., (Thieme.

Background: Limb salvage after lower extremity (LE) trauma requires optimal blood flow for successful microsurgical reconstruction. Peripheral arterial disease (PAD) decreases LE perfusion, affecting wound healing. Patients who present with LE trauma may have undiagnosed PAD, particularly those with atherosclerotic risk factors. This study assesses outcomes after LE salvage in patients at risk for PAD., Methods: This retrospective review evaluated patients who underwent LE reconstruction at a level 1 trauma center between 2007 and 2022. Patients with a nontraumatic mechanism of injury, missing postoperative records, and unspecified race were excluded. Demographics, flap characteristics, and postoperative complications were abstracted. The prevalence of LE PAD was calculated using a validated risk assessment tool., Results: At our institution, 285 LE flaps performed on 254 patients were included in the study. Patients were categorized by prevalence of PAD, including 12 (4.7%) with high risk, 45 (17.7%) with intermediate risk, and 197 (77.6%) patients with low risk. The high-risk cohort had higher rates of partial flap necrosis ( P = 0.037), flap loss ( P = 0.006), and amputation ( P < 0.001) compared with the low-risk group. Fewer high-risk patients achieved full ambulation compared with the low-risk ( P = 0.005) cohort. Overall flap survival and limb salvage rates were 94.5% and 96.5%, respectively. Among the intermediate- and high-risk cohorts, only 50.9% of patients received a preoperative vascular assessment, and 3.8% received a vascular surgery consultation., Conclusions: Peripheral arterial disease represents a reconstructive challenge to microvascular surgeons. Patients with high-risk for PAD had higher rates of partial flap necrosis, flap loss, and amputation. In the setting of trauma, emphasis should be placed on preoperative vascular assessment for patients at risk of having undiagnosed PAD. Prospective studies collecting ankle-brachial index assessments and/or angiography will help validate this study's findings., Competing Interests: Conflicts of interest and sources of funding: none declared., (Copyright © 2023 Wolters Kluwer Health, Inc.

As of November 2021, TikTok has one billion monthly active users and is recognized as the most engaging social media platform. TikTok has seen a surge in users and content creators, ranging from athletes to medical professionals. In the past year, content creators have utilized the app to advocate for social reforms, education, and other uses that were not previously considered. Breast cancer is the most commonly diagnosed cancer in women, with an expected 281,550 new cases of invasive breast cancer in 2021. As more individuals with breast cancer choose to undergo resection, the demand for autologous fat grafting in breast reconstruction has increased due to the natural look and feel of breast tissue. The purpose of this article is to analyze content related to breast reconstruction with fat grafting found on TikTok and recommend methods to improve patient education, care, and outcomes. We searched TikTok on November 1, 2021, for videos using the phrase "breast reconstruction with fat grafting." The top 200 videos retrieved from the TikTok search algorithm were analyzed, and all commentaries, duplicates, and nonrelevant videos were removed. Video characteristics were collected, and two independent reviewers generated a DISCERN score A total of 131 videos were included in the study. They were found to have a combined 1,871,980 likes, 41,113 comments, and 58,662 shares. The videos had an average DISCERN score of 2.16. Content creators had an overall low DISCERN score in items involving the use of references, disclosure of risks for not obtaining treatment, and support for shared decision-making. When stratified, the DISCERN score was higher for videos created by physicians (DISCERN average 2.48) than for videos created by nonphysicians (DISCERN average 1.99; p  < 0.001). Content creators can improve the quality of their videos by disclosing treatment risks, benefits and risks, discussing risks for not obtaining treatment, and advocating for shared decision-making. Furthermore, including citations and academic references may offer increased credibility and promote evidence practice. This article is limited by the variability seen on the TikTok platform that is influenced by algorithmic trends. The top 200 search results vary, making each compilation of videos selected for analysis unique. Furthermore, although DISCERN is a reliable source to assess patient information, it has not been tested for its reliability with videos such as on TikTok. Despite TikTok being developed as a social media platform, it has shown to be a medium for patient outreach and an educational tool., Competing Interests: Conflict of Interest None declared., (The Korean Society of Plastic and Reconstructive Surgeons.

Objective: The natural history and management of intramural hematoma (IMH) has varied significantly worldwide. From the present retrospective analysis of our institutional database, we have reported the long-term results from medical and surgical management of types A and B IMH., Methods: Computed tomography reports completed at our tertiary care hospital from July 2007 to July 2020 were used to identify patients with IMH with a thickness of ≥7 mm. Those with IMH directly related to trauma, previous aortic surgery, penetrating atheromatous ulcer, dissection flap, or an iatrogenic source and those who had never received any treatment of IMH at presentation were excluded., Results: A total of 54 patients with IMH had met the inclusion and exclusion criteria. Of the 54 patients, 24 had presented with Stanford type A. Of these 24 patients, 10 had initially undergone surgery and 14 had initially received medical treatment. Two patients in the medical group had subsequently undergone surgery. In addition, 30 patients had presented with type B IMH and had initially received medical treatment, with 3 eventually requiring surgical intervention. In-hospital survival was 90% for type A IMH treated surgically, 93% for type A IMH treated medically, and 97% for type B IMH treated medically. At the last follow-up imaging study of the medically treated patients, 36% of those with type A IMH and 31% of those with type B IMH had experienced complete resolution of IMH at 3.7 and 31.5 months respectively, without surgical intervention. The development of an aortic aneurysm at the site of a previous IMH had occurred in 18% (2 of 11) and 12% (3 of 26) of the type A medical and type B medical cohorts. The overall rate of aortic aneurysm formation in the region of IMH or in another segment was 50%. No difference was found in long-term survival between the three cohorts at a mean follow-up of 22.8 months., Conclusions: A role appears to exist for medical treatment with anti-impulse therapy for appropriately selected patients with type A IMH. These patients must be followed up closely clinically and radiographically for signs of deterioration in the short- and long-term phases of their care. They can achieve long-term survival similar to that of surgically treated type A IMH and medically treated type B IMH patients using this algorithm. However, they might require late surgical intervention, especially for aneurysmal disease., (Copyright © 2022 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.)

Purpose: Computed tomography (CT) is currently the standard for evaluation of intra-abdominal injury (IAI) after BAT. Pediatric patients receiving CT scans based on adult clinical protocols are potentially exposed to unnecessary radiation. The purpose of this study is to determine the rate of CT scans before and after implementation of a pediatric BAT decision tool., Methods: We adapted and implemented an evidence-based decision tool for pediatric BAT based on five clinical variables. We reviewed patient charts 18 months pre- and post-implementation. Demographics and outcomes were compared using Chi-square and Fisher's exact test, accordingly., Results: The pre and post-implementation groups were uniform when comparing age, sex, mechanism, and Injury Severity Score. The decision tool was utilized in 85% of patients post-implementation. Fewer CT scans were obtained in the post-implementation group (28 vs. 21%, p = 0.215) with no missed injuries or late diagnoses., Conclusion: Implementation of a pediatric BAT decision tool decreased CT usage and radiation exposure without an obvious compromise to patient care. This experience supports the utilization of these tools for the assessment of IAI after BAT and have resulted in more selective use of CT during pediatric BAT in our program., (© 2021.

Background: Insurance coverage for microsurgical lymphatic surgery continues to be sporadic, as the procedures continue to be labeled investigational. The objective of this study was to examine the typical payment patterns of our clinical practice for microsurgical lymphatic procedures., Methods: We performed a single center, single surgeon retrospective case review for all lymphovenous bypass and vascularized lymph node transfer cases preformed from 2018 to 2020. We then queried the available financial data and calculated total charges, total paid by insurance, total variable cost (cost to the hospital), and the contribution margin (difference between the amount paid and variable cost). Descriptive statistics were then collected for each subgroup for analysis., Results: Financial data were collected on 22 patients with 10 left-sided, 11 right-sided and one bilateral procedure performed. Seven procedures were done prophylactically, and 15 were done for existing lymphedema. An estimated 10 of 22 patients (45%) had Medicare, Medicaid, or Tricare, with the remaining having private insurance. We calculated an average cost of $48,516.73, with average payment of $10,818.68, average variable cost of $5,567.10, for a contribution margin of +$5251.58., Conclusions: Lymphedema remains a common complication of surgery and a significant cost burden to patients and the healthcare system. Microsurgical procedures offer several advantages over medical therapy. In our practice, we were routinely reimbursed for both prophylactic and therapeutic procedures with positive contribution margins for the hospital and ratios similar to other surgeries. Despite the limitations of a small retrospective review, there is no similar published cost analysis data in the current literature., Competing Interests: Disclosure: All the authors have no financial interest to declare in relation to the content of this article. This study received no funding., (Copyright © 2021 The Authors. Published by Wolters Kluwer Health, Inc. on behalf of The American Society of Plastic Surgeons.)

Background: A major factor contributing to global trauma mortality and morbidity is the lack of effective prehospital trauma services in developing settings. We developed a 2-d training course for nondoctor first responders featuring high-fidelity simulation and video-assisted debriefing, self-directed learning videos, and native language instruction., Materials and Methods: A pilot session was conducted in Jodhpur, Rajasthan. Eighteen local instructors were recruited to train 48 layperson first responders in 10 essential subjects. Didactic sessions of 15-20 min consisting of self-directed learning videos were followed by 30-40 min skill sessions featuring high-fidelity simulation, and concluded with 15-20 min video-debriefing periods. Changes in competence were evaluated using pretraining and posttraining surveys., Results: Results demonstrated that statistically significant competence increases in all areas of trauma management assessed: airway (t[46] = 7.30, P < 0.000), hemorrhage (t[46] = 9.96, P < 0.000), fractures (t[46] = 9.22, P < 0.000), cervical spine injury (t[46] = 12.12, P = 0.000), chest injury (t[46] = 7.84, P < 0.000), IV line placement (t[46] = 4.36, P < 0.000), extrication (t[46] = 2.81, P < 0.005), scene assessment (t[46] = 7.06, P < 0.000), triage (t[46] = 5.92, P < 0.000), and communication (t[46] = 5.56, P < 0.000). Highest increases in competence were observed in cervical spine injury and hemorrhage management, with lowest increases in IV line placement and extrication., Conclusions: Results suggest this approach may be effective in imparting prehospital trauma management concepts to layperson first responders. This study highlights an innovative educational avenue through which trauma management capacity can be enhanced in developing settings., (Copyright © 2015 Elsevier Inc. All rights reserved.)
