Background and Purpose: Mechanical thrombectomy (MT) along with emergent carotid stent placement (eCAS) has been suggested to have a greater benefit in patients with tandem lesions (TL), compared with other strategies of treatment. Nonetheless, there is no agreement on whether the intracranial occlusion should be treated before the cervical ICA lesion, or vice versa. In this retrospective multicenter study, we sought to compare clinical and procedural outcomes of the 2 different treatment approaches in patients with TL., Materials and Methods: The prospective databases of 17 comprehensive stroke centers were screened for consecutive patients with TL who received MT and eCAS. Patients were divided in 2 groups based on whether they received MT before eCAS (MT-first approach) or eCAS before MT (eCAS-first approach). Propensity score matching was used to estimate the effect of the retrograde-versus-anterograde approach on procedure-related and clinical outcome measures. These included the modified TICI score 2b-3, other procedure-related parameters and adverse events after the endovascular procedure, and the ordinal distribution of the 90-day mRS scores., Results: A total of 295 consecutive patients were initially enrolled. Among them, 208 (70%) received MT before eCAS. After propensity score matching, 56 pairs of patients were available for analysis. In the matched population, the MT-first approach resulted in a higher rate of successful intracranial recanalization (91% versus 73% in the eCAS-first approach, P  = .025) and a mean shorter groin-to-reperfusion time (72 [SD, 38] minutes versus 93 [SD, 50] minutes in the anterograde approach, P  = .017). Despite a higher rate of efficient recanalization in the MT-first group, we did not observe a significant difference regarding the ordinal distribution of the 90-day mRS scores. Rates of procedure-related adverse events and the occurrence of both parenchymal hemorrhage types 1 and 2 were comparable., Conclusions: Our study demonstrates that in patients with TL undergoing endovascular treatment, prioritizing the intracranial occlusion is associated with an increased rate of efficient MT and faster recanalization time. However, this strategy does not have an advantage in long-term clinical outcome. Future controlled studies are needed to determine the optimal treatment technique., (© 2025 by American Journal of Neuroradiology.)

Background: The aim of our study was to find predictors of parenchymal hematoma (PH) and clinical outcome after mechanical thrombectomy (MT) in patients with large vessel occlusion (LVO) and baseline large infarct., Methods: The databases of 16 stroke centers were retrospectively screened for patients with anterior circulation LVO and baseline Alberta Stroke Program Early CT Score (ASPECTS) ≤5 that received MT. Procedural parameters, including the number of passes during first and second technique of MT, were recorded. Outcome measures were occurrence of PH type 2 and any type of PH after MT, and the 90-day modified Rankin Scale (mRS) score of 0-3 and 0-2., Results: In total, 408 patients were available for analysis. A higher number of passes in the second technique was predictive of PH type 2 (odds ratio (OR) - 3.204, 95% confidence interval (CI) 1.140 to 9.005), whereas procedure conducted under general anesthesia was associated with lower risk (OR 0.127, 95% CI 0.002 to 0.808). The modified thrombolysis in cerebral infarction grade 2c-3 was associated with the mRS score 0-3 (OR 3.373, 95% CI 1.891 to 6.017), whereas occurrence of PH type 2 was predictive of unfavorable outcome (OR 0.221, 95% CI 0.063 to 0.773). Similar results were found for the mRS score 0-2 outcome measure., Conclusion: In patients with large ischemic core, a higher number of passes during MT and procedure not conducted under general anesthesia are associated with increased rate of PH type 2, that negatively impact the clinical outcome. Our data outline a delicate balance between the need of a complete recanalization and the risk of PH following MT., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2025.

Background: Recent randomized trials have shown the benefit of mechanical thrombectomy (MT) also in patients with an established large ischemic core., Aims: The purpose of this study was to define baseline predictors of clinical outcome in patients with large vessel occlusion (LVO) in the anterior circulation and an Alberta Stroke Program Early CT score (ASPECTS) ⩽ 5, undergoing MT., Material and Methods: The databases of 16 comprehensive stroke centers were retrospectively screened for patients with LVO and ASPECTS ⩽5 that received MT. Baseline clinical and neuroradiological features, including the differential contribution of all ASPECTS regions to the composite score, were collected. Primary clinical outcome measure was a 90-day modified Rankin Scale (mRS) score of 0-2. Statistical analysis used a logistic regression model and random forest algorithm., Results: A total of 408 patients were available for analysis. In multivariate model, among baseline features, lower age (odd ratio (OR) = 0.962, 95% confidence interval (CI) = 0.943-0.982) and lower National Institute of Health Stroke Scale (NIHSS) score (OR = 0.911, 95% CI = 0.862-0.963) were associated with the mRS score 0-2. Involvement of the M2 (OR = 0.398, 95% CI = 0.206-0.770) or M4 (OR = 0.496, 95% CI = 0.260-0.945) ASPECTS regions was associated with an unfavorable outcome. Random forest analysis confirmed that age and baseline NIHSS score are the most important variables influencing clinical outcome, whereas involvement of cortical regions M5, M4, M2, and M1 can have a negative impact., Conclusion: Our retrospective analysis shows that, along with age and baseline clinical impairment, presence of early ischemic changes involving cortical areas has a role in clinical outcome in patients with large ischemic core undergoing MT., Data Access Statement: The data that support the findings of this study are available upon reasonable request., 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.

Background: This study investigates the impact of general anesthesia (GA) versus conscious sedation/local anesthesia (CS/LA) on the outcome of patients with minor stroke and isolated M2 occlusion undergoing immediate mechanical thrombectomy (iMT)., Methods: The databases of 16 comprehensive stroke centers were retrospectively screened for consecutive patients with isolated M2 occlusion and a baseline National Institutes of Health Stroke Scale score ≤5 who received iMT. Propensity score matching was used to estimate the effect of GA versus CS/LA on clinical outcomes and procedure-related adverse events. The primary outcome measure was a 90-day modified Rankin Scale (mRS) score of 0-1. Secondary outcome measures were a 90-day mRS score of 0-2 and all-cause mortality, successful reperfusion, procedural-related symptomatic subarachnoid hemorrhage, intraprocedural dissections, and new territory embolism., Results: Of the 172 patients who were selected, 55 received GA and 117 CS/LA. After propensity score matching, 47 pairs of patients were available for analysis. We found no significant differences in clinical outcome, rates of efficient reperfusion, and procedural-related complications between patients receiving GA or LA/CS (mRS score 0-1, P = 0.815; mRS score 0-2, P = 0.401; all-cause mortality, P = 0.408; modified Treatment in Cerebral Infarction score 2b-3, P = 0.374; symptomatic subarachnoid hemorrhage, P = 0.082; intraprocedural dissection, P = 0.408; new territory embolism, P = 0.462)., Conclusions: In patients with minor stroke and isolated M2 occlusion undergoing iMT, the type of anesthesia does not affect clinical outcome or the rate of procedural-related complications. Our results agree with recent data showing no benefit of one specific anesthesiologic procedure over the other and confirm their generalizability also to patients with minor baseline symptoms., (Copyright © 2023 The Author(s).

Background: Patients with minor stroke and M2 occlusion undergoing best medical management (BMM) may face early neurological deterioration (END) that can lead to poor long-term outcome. In case of END, rescue mechanical thrombectomy (rMT) seems beneficial. Our study aimed to define factors relevant to clinical outcome in patients undergoing BMM with the possibility of rMT on END, and find predictors of END., Methods: Patients with M2 occlusion and a baseline National Institutes of Health Stroke Scale (NIHSS) score≤5 that received either BMM only or rMT on END after BMM were extracted from the databases of 16 comprehensive stroke centers. Clinical outcome measures were a 90-day modified Rankin Scale (mRS) score of 0-1 or 0-2, and occurrence of END., Results: Among 10 169 consecutive patients with large vessel occlusion admitted between 2016 and 2021, 208 patients were available for analysis. END was reported in 87 patients that were therefore all subjected to rMT. In a logistic regression model, END (OR 3.386, 95% CI 1.428 to 8.032), baseline NIHSS score (OR 1.362, 95% CI 1.004 to 1.848) and a pre-event mRS score=1 (OR 3.226, 95% CI 1.229 to 8.465) were associated with unfavorable outcome. In patients with END, successful rMT was associated with favorable outcome (OR 4.549, 95% CI 1.098 to 18.851). Among baseline clinical and neuroradiological features, presence of atrial fibrillation was a predictor of END (OR 3.547, 95% CI 1.014 to 12.406)., Conclusion: Patients with minor stroke due to M2 occlusion and atrial fibrillation should be closely monitored for possible worsening during BMM and, in this case, promptly considered for rMT., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: The purpose of this study was to evaluate the effectiveness of mechanical thrombectomy (MT) in patients with isolated M2 occlusion and minor symptoms and identify possible baseline predictors of clinical outcome., Methods: The databases of 16 high-volume stroke centers were retrospectively screened for consecutive patients with isolated M2 occlusion and a baseline National Institutes of Health Stroke Scale (NIHSS) score ≤5 who received either early MT (eMT) or best medical management (BMM) with the possibility of rescue MT (rMT) on early neurological worsening. Because our patients were not randomized, we used propensity score matching (PSM) to estimate the treatment effect of eMT compared with the BMM/rMT. The primary clinical outcome measure was a 90-day modified Rankin Scale score of 0-1., Results: 388 patients were initially selected and, after PSM, 100 pairs of patients receiving eMT or BMM/rMT were available for analysis. We found no significant differences in clinical outcome and in safety measures between patients receiving eMT or BMM/rMT. Similar results were also observed after comparison between eMT and rMT. Concerning baseline predicting factors of outcome, the involvement of the M2 inferior branch was associated with a favorable outcome., Conclusion: Our multicenter retrospective analysis has shown no benefit of eMT in minor stroke patients with isolated M2 occlusion over a more conservative therapeutic approach. Although our results must be viewed with caution, in these patients it appears reasonable to consider BMM as the first option and rMT in the presence of early neurological deterioration., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: Middle meningeal artery embolization (MMAE) for the management of chronic subdural hematomas (CSDH) with ethylene vinyl alcohol (EVOH) causes an evident patient discomfort due to meningeal nociceptors stimulation. The aim of this study was to assess safety and efficacy of intra-arterial lidocaine (IAL) before MMAE of CSDH with EVOH., Methods: We analyzed all consecutive patients with bilateral CSDH undergoing MMAE with EVOH. We used a monolateral IAL injection, with casual allocation. We assessed the headache felt by patients during embolization with the visual analog scale (VAS) and compared scores obtained after embolization of both sides. We followed the STROBE guidelines for case-control studies. Paired t-test and χ 2 test were used to compare the distribution of variables in IAL vs control group., Results: Between September 2021 and March 2023, 32 patients underwent bilateral MMAE with EVOH for a CSDH. Lidocaine treatment resulted in a substantially lower VAS score compared to the control group (median 3 vs 7, p < 0.001), with no substantial side effect. Compliance also benefited from lidocaine administration., Conclusions: In patients with CSDH undergoing MMAE, IAL seems to reduce pain sensation associated with EVOH injection and to increase patients' compliance during treatment.

Objective: In this study, the authors retrospectively evaluated the effectiveness and the safety of non-surgical middle cerebral artery (MCA) aneurysms treated via the implantation of a flow diverter device (FDD)., Methods: Clinical, procedural and follow-up data were analyzed in order to evaluate the safety and effectiveness of the treatment with the FDD in complex MCA aneurysms. Safety was assessed recording (intra-procedural, peri-procedural and delayed) complications in order to determine the morbidity and mortality rates. Functional outcome was evaluated with modified Rankin Scale (mRS) prior and after the endovascular procedure. To assess the efficacy, midterm and long-term clinical, angiographic and cross-sectional imaging follow-ups were recorded., Results: 47 patients (21 males; 26 females) with MCA aneurysms were treated with FDD. 7 were ruptured. 21 aneurysms were saccular, 19 dissecting, 3 fusiform, 2 blood blister-like and 2 were pseudo-aneurysms. 14 aneurysms were small, 23 large and 10 giant, with a mean size of 15.3 mm. 8 aneurysms were recurrent (Raymond-Roy class III): 2 patients had an aneurysmal sac recanalization after being treated with simple coiling and 6 after being treated with microsurgical clipping. In 4 cases (8.5%), more than one FDD was telescopically positioned in order to treat the aneurysm, for a total of 54 FDDs used. The overall mortality rate was 2.1% (1/47) and the overall morbidity rate was 8.6% (4/47). Midterm neuroimaging follow-ups showed the complete occlusion of the aneurysm in 63% cases, which became 91% at the end of the follow-up., Conclusions: FDD is a safe and effective tool that can be used in the treatment of complex MCA aneurysms, where conventional neurosurgical treatments can be challenging or ineffective., Competing Interests: Declaration of Competing Interest This research received no specific grant from any funding agency in the public, commercial or not-for-profit sectors.

Although several innovations in techniques and implantable devices were reported over the last decades, a consensus on the best endovascular treatment for intracranial aneurysms originating from the posterior communicating artery is still missing. This work investigates radiological outcomes of different endovascular techniques for posterior communicating artery aneurysms treatment in a retrospective multi-centric cohort. We included patients endovascularly treated for posterior communicating artery aneurysms from 2015 through 2020 in six tertiary referral hospitals. We evaluated the relationship between patients and aneurysms characteristics, baseline neurological status, radiological outcomes, and the different endovascular techniques. Overall, 250 patients were included in this study. Simple coiling was the most frequent treatment in 171 patients (68%), followed by flow-diverter stenting in 32 cases (13%). Complete occlusion was reported in 163 patients (65%), near-complete occlusion in 43 (17%), and incomplete occlusion in 44 (18%). Radiological follow-up was available for 247 (98%) patients. The occlusion rate was stable in 149 (60%), improved in 49 (19%), and worsened in 51 (21%). No significant difference in exclusion rate was seen between ruptured and unruptured aneurysms at the last follow-up (p = 0.4). Posterior communicating artery thrombosis was reported in 25 patients (9%), transient ischemic attack in 6 (2%), and in 38 patients (15%), subsequent procedures were needed due to incomplete occlusion or reperfusion. Endovascular strategies for posterior communicating artery aneurysms represent effective and relatively safe treatments. Simple coiling provides a higher immediate occlusion rate, although recanalization has been frequently reported, conversely, flow-diversion devices provide good long-term radiological outcomes., Competing Interests: The authors declare no conflict of interest., (© 2022 The Author(s).

Background: Symptomatic intracranial vertebro-basilar stenoses (SIVBS) are associated with high risk of recurrent ischemic stroke, even in patients receiving the best medical treatment. Although medical treatment is still the standard of care, non-responding patients may require endovascular treatment; balloon-mounted coronary stents (BMCS) could be successfully employed. This study aims to retrospectively analyze our high volume Interventional Neurovascular center ten-year experience in the off-label use of BMCS for the treatment of SIVBS, in order to assess its feasibility and safety., Methods: We retrospectively analyzed all consecutive patients with SIVBS treated with BMCS in the last ten years in our center. Data collected included patient demographics, stenosis location and characteristics, early (<30 days) and late (>30 days) stroke and death rates, pre-symptomatic and post-treatment modified Rankin Scale (mRS) scores., Results: 42 patients (35 males, average age 65,7 ± 10,7, range 37-85) with SIVBS were treated with BMCS. Thirty-four (80,9%) patients were symptomatic despite ongoing best medical therapy; eight (19,1%) patients were treated in emergency for large vessel occlusion, due to an underlying stenosis. BMCSs were successfully deployed in all cases. The incidence of stroke and death at one month was 7,1% (3/42). The incidence of TIA, stroke and death at long-term follow-up (average time of 3 years) was 14,3% (4,7 per 100 person-years). At long-term follow-up, mRS improved in 82% of patients who underwent elective treatment., Conclusions: In our experience, the off-label use of BMCS in the endovascular treatment of SIVBS resistant to medical treatment is feasible and safe., (Copyright © 2020 Elsevier Inc.

Objectives: To retrospectively analyze interventional radiology (IR) activity changes in the COVID-19 era and to describe how to safely and effectively reorganize IR activity., Methods: All IR procedures performed between January 30 and April 8, 2020 (COVID-era group) and the same 2019 period (non-COVID-era group) were retrospectively included and compared. A sub-analysis for the lockdown period (LDP: 11 March-8 April) was also conducted. Demographic, hospitalization, clinical, and procedural data were obtained for both groups and statistically compared with univariable analysis., Results: A total of 1496 procedures (non-COVID era, 825; COVID era, 671) performed in 1226 patients (64.9 ± 15.1 years, 618 women) were included. The number of procedures decreased by 18.6% between 2019 and 2020 (825 vs 671, p < .001), with a reduction by 48.2% in LDP (188 vs 363, p < .0001). In the LDP COVID era, bedside procedures were preferred (p = .013), with an increase in procedures from the intensive care unit compared with the emergency department and outpatients (p = .048), and an increased activity for oncological patients (p = .003). No incidents of cross-infection of non-infected from infected patients and no evidence of COVID-19 infection of healthcare workers in the IR service was registered., Conclusions: Coronavirus disease outbreak changed the interventional radiology activity with an overall reduction in the number of procedures. However, this study confirms that interventional radiology continuum of care can be safely performed also during the pandemic, following defined measures and protocols, taking care of all patients., Key Points: • Coronavirus disease pandemic determined a reduction of interventional radiology activity as compared to the same period of the previous year. • Interventional radiology procedures for life-threatening conditions and non-deferrable oncologic treatments were prioritized as opposed to elective procedures. • Strict adoption of safe procedures allowed us to have until now no incidents of cross-infection of non-infected from infected patients and no evidence of COVID-19 infection of HCWs in the IR service.

Background: Endovascular therapy with liquid embolic agents (LEAs) is the gold standard for the treatment of cerebral dural arteriovenous fistulas (cDAVFs). The aim of the study is to retrospectively evaluate effectiveness, safety, and midterm follow-up results of endovascular treatment of cDAVFs using SQUID 12., Methods: Between June 2017 and January 2020 the authors retrospectively reviewed clinical, demographic and embolization data of 19 consecutive patients with cDAVF who underwent embolization using SQUID 12. The number of arteries catheterized for each procedure, the total amount of embolic agent, the occlusion rate, the injection time, any technical and/or clinical complications were recorded. Mid-term follow-up with DSA was reviewed., Results: 20 procedures were performed in 19 patients. A transarterial approach was accomplished in 19 procedure; a combined transvenous-transarterial approach was realized in 1 treatment. The average time of injection was 33 minutes (2-82 minutes), and the average amount of SQUID 12 was 2.8 mL (0.5-6 mL). Complete angiographic cure at the end of the procedure was achieved in 17 patients. No major periprocedural adverse events were recorded. Mid-term follow-up was achieved in 15 out of 19 patients and confirmed complete occlusion of the cDAVFs in 13/15 patients (87%); in 2 of the initially cured patients a small relapse was detected., Conclusions: The treatment of the cDAVFs using SQUID 12 was effective and safe. The lower viscosity seems to allow an easier penetration of the agent with a high rate of complete occlusion of the cDAVFs.

Background: Postinfectious Moyamoya syndrome (MMS) is a rare vasculopathy that can follow meningitis. Only 9 cases of MMS after meningitis have been reported in the literature. We present a unique case of MMS after meningitis caused by Aspergillus fumigatus and Escherichia coli and review all cases of MMS postmeningitis in the literature., Case Description: A 41-year-old man was admitted to our emergency department for sudden hypoesthesia in the left arm and an intense headache not responsive to drugs. Computed tomography scan and magnetic resonance imaging showed acute ischemic lesions in the right centrum semiovale associated with bilateral chronic watershed cerebral ischemic lesions. The cerebral digital subtraction angiography documented a typical Moyamoya pattern. In anamnesis, the patient suffered from meningitis caused by A. fumigatus and E. coli infection after neurosurgery for subependymoma of the fourth ventricle 2 years before. Laboratory tests, clinical investigation, and imaging ruled out any other cause of vasculopathy and led to the final diagnosis of postinfectious MMS. The patient started medical therapy with oral acetyl salicylic acid, verapamil, and prednisone while surgical approach was excluded in the first instance., Conclusions: Physicians should be aware of an uncommon but severe complication of meningitis such as MMS, even several years after the infection. Neuroimaging is essential for the diagnosis and to exclude other causes of neurologic symptoms in these patients., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Purpose: To report a single-center experience with non-thyroid causes of extraocular muscle enlargement (EME), describing the association between clinical-radiological findings at presentation and the final histopathological diagnosis., Methods: Retrospective consecutive case series of 59 patients with single or multiple EME on orbital imaging, in the absence of an etiological diagnosis at the time of presentation. All patients were submitted to orbital muscle biopsy in order to achieve a final etiological diagnosis. Patients with a confirmed diagnosis of thyroid-associated orbitopathy and vascular causes of EME which were angiographically and clinically diagnosed were excluded. Orbital ultrasound and radiologic evaluation (CT and/or MRI) were performed before surgery in all cases. Main outcomes measured included initial clinical-radiological findings and final histopathological features of EME., Results: A diagnosis of lymphoma was confirmed in 13 cases (22%). Sixteen cases (27%) were diagnosed as orbital inflammatory disease including nonspecific idiopathic orbital inflammatory disease in 9 cases, IgG4-related disease in 4 cases, and sclerosing idiopathic orbital inflammatory disease in 3 cases. In 11 patients (18%), a diagnosis of metastatic tumor was made, whereas sarcoidosis, vascular malformations, Erdheim-Chester, and necrobiotic xanthogranuloma were diagnosed in 8 eyes (13.5%). Three patients (5%) with single muscle enlargement developed Graves disease 10 months later. Four patients (6.7%) were diagnosed with granulomatosis with polyangiitis. In 2 cases (3.3%), the diagnosis was unknown, with inconclusive biopsy results. Differential patterns for inflammatory/vascular, lymphomatous and metastatic EME were identified based on age and gender distribution and clinical-radiological characteristics at presentation., Conclusions: Initial clinical and radiological features may orientate the differential diagnosis of non-thyroid EME.

Background: Paralleling the growth of bariatric surgery, the demand for post-bariatric body-contouring surgery is increasing. Weight loss is the main cause, although not the only one, that drives patients to arm lift surgery. Several surgical techniques have been proposed over the years. Our aim was to consider the complications and outcomes according to the performed technique, through a wide review of the literature., Methods: A search on PubMed/Medline was performed using "brachioplasty", "upper arm lifting", and "techniques" as key words. Embase, Medline (OvidSP), Web of Science, Scopus, PubMed publisher, Cochrane, and Google Scholar were searched as well. As inclusion criteria, we selected the clinical studies describing techniques of brachioplasty. We excluded the papers in which complications related to brachioplasty were not specified. We also excluded literature-review articles., Results: We found 27 studies from 1995 to 2015. Overall, 1065 patients were treated. Different techniques were applied. Complications were observed in 308/1065 patients (28.9%). The most frequent complications were hypertrophic scarring, seroma and hematoma. Surgical revision rate ranged from 0 to 21 percent. Nerve damage occurred in a modest percentage of patients (16/1065, 1.5%). No major complications, such as thromboembolism and sepsis, were observed., Conclusions: Brachioplasty is a safe surgical procedure. All the brachioplasty techniques showed positive outcomes, in term of patients' satisfaction and clinical results. Nevertheless, minor complications occurred in a high percentage of patients, regardless the performed surgical procedure. Patients should be informed about the possible formation of hypertrophic scars and nerve injuries.

Extramammary Paget disease (EMPD) is a rare neoplasm. The clinical case of a 55-year-old man with a two-year history of a pruritic, painless erythematous skin rash on the inguinal region and scrotum is described. After a delay due to improper diagnosis and improper treatments, the patient came to the attention of the Division of plastic surgery. He underwent a punch biopsy and the pathology report came back as EMPD. Surgical excision was carried out, and an abdominal advancement cutaneous flap was performed for the defect repair. This is the first description of a reconstruction after surgical removal of inguinal EMPD with a flap of this type and we think that this type of treatment can be useful and reliable for disease localization in the groin area, especially for patients that present an excess of abdominal skin.
