“…Intracranial atherosclerotic stenoses pose a challenge for EVT in AIS patients as they increase intraprocedural re-occlusion 23 . A recent study in AIS patients with intracranial atherosclerosis-related large vessel occlusion showed that balloon angioplasty as a first-choice recanalization strategy has a higher efficiency in recanalization and better functional outcomes at 90 days compared to thrombectomy 14 .…”

“…Endovascular therapy included stent retriever, aspiration catheter, balloon angioplasty and combination of different techniques. Balloon angioplasty was performed as the therapeutic method of first choice for recanalization in AIS patients who exhibited the “first-pass effect” of the microcatheter, in which blood was already flowing through the occluded vessel when the microcatheter was first passed and then withdrawn to the proximal side of the occluded vessel during EVT 14 . The number of passes of catheter needed to achieve recanalization or until the end of procedure and the location of endovascular therapy were documented.…”

Background: Perioperative ischemic stroke is a rare but devastating complication. Mechanical thrombectomy is a promising therapeutic method, but very little data is available on its efficacy and safety. This study aims to answer this question by comparing the clinical outcomes of perioperative and community-onset stroke patients after endovascular therapy. Methods: A retrospective cohort study was conducted on a total of 35 perioperative and 584 community-onset acute ischemic stroke patients who underwent endovascular thrombectomy at our hospital over the past 3.5 years. The recanalization rate, clinical recovery and cerebral hemorrhage within 90 days after therapy were compared between these two patient groups. Results: Endovascular thrombectomy provided perioperative and community-onset ischemic stroke patients with comparable rates of successful reperfusion (mTICI ? 2b grade) (97.1% vs. 97.3%; P = 0. 967) and favorable functional recovery (mRS ? 2) (51.4% vs. 43.3%, P = 0.348), with no increase in severe intracranial hemorrhage (0% vs. 2.6% and 1.0%, for hematoma ? 30% of infarcted tissue and intraventricular hemorrhage, respectively) within 90 days. In addition, perioperative stroke patients had higher prevalence of atrial fibrillation (42.9 % vs. 26.7 %; P = 0.038) and intracranial cerebral artery stenosis without clear embolism (17.1 % vs. 3.8 %; P < 0.001) than community-onset stroke patients. Conclusions: Endovascular thrombectomy is an effective and safe therapeutic approach for patients with perioperative ischemic stroke, although the results need to be validated by further studies with larger populations. Atrial fibrillation and large artery stenosis may contribute to the pathogenesis of perioperative ischemic stroke.
