Endovascular thrombectomy for large ischemic strokes: An updated living systematic review and meta-analysis of randomized clinical trials.

BACKGROUND: Recent studies indicate endovascular thrombectomy (EVT) as a safe, effective treatment for acute ischemic stroke (AIS) with large ischemic regions. Our study updates an ongoing living systematic review and meta-analysis of randomized controlled trials (RCTs) comparing outcomes of EVT to medical management only. METHODS: We searched MEDLINE, EMBASE, and the Cochrane Library for RCTs comparing EVT to medical management in AIS patients with large ischemic areas. Using fixed-effect models, we conducted a meta-analysis to compare functional independence, mortality, and symptomatic intracranial hemorrhage (sICH) between EVT and standard medical management. We evaluated bias risk with the Cochrane tool and graded the certainty of evidence using the GRADE approach. RESULTS: Of 1363 new citations, we included six RCTs with a total of 1876 patients. We found low-certainty evidence of improved functional independence (risk difference [RD] 29.9%, 95% CI 17.2% to 46.9%), increase in sICH (RD 2.6%, 95% CI 0.3% to 6.4%), and a non-significant decrease in mortality (RD -1.8%, 95% CI -3.9% to 0.6%) for AIS patients with large infarcts who underwent EVT compared to medical management only. CONCLUSION: Our revised meta-analysis suggests low-certainty evidence that there is improved functional independence, a non-significant decrease in mortality, and an increase in sICH among AIS patients with large infarcts who undergo EVT compared to those receiving medical management alone.

Factors Affecting Selection of TraineE for Neurointervention (FASTEN).

BACKGROUND AND IMPORTANCE: Neurointervention is a very competitive specialty in the United States due to the limited number of training spots and the larger pool of applicants. The training standards are continuously updated to ensure solid training experiences. Factors affecting candidate(s) selection have not been fully established yet. Our study aims to investigate the factors influencing the selection process. METHODS: A 52-question survey was distributed to 93 program directors (PDs). The survey consisted of six categories: (a) Program characteristics, (b) Candidate demographics, (c) Educational credentials, (d) Personal traits, (e) Research and extracurricular activities, and (f) Overall final set of characteristics. The response rate was 59.1%. As per the programs' characteristics, neurosurgery was the most involved specialty in running the training programs (69%). Regarding demographics, the need for visa sponsorship held the greatest prominence with a mean score of 5.9 [standard deviation (SD) 2.9]. For the educational credentials, being a graduate from a neurosurgical residency and the institution where the candidate's residency training is/was scored the highest [5.4 (SD = 2.9), 5.4 (SD = 2.5), respectively]. Regarding the personal traits, assessment by faculty members achieved the highest score [8.9 (SD = 1)]. In terms of research/extracurricular activities, fluency in English had the highest score [7.2 (SD = 1.9)] followed by peer-reviewed/PubMed-indexed publications [6.4 (SD = 2.2)]. CONCLUSION: Our survey investigated the factors influencing the final decision when choosing the future neurointerventional trainee, including demographic, educational, research, and extracurricular activities, which might serve as valuable guidance for both applicants and programs to refine the selection process.
