[Endovascular thrombectomy in patients with intracranial large artery occlusion and atrial fibrillation].

Objective: To investigate the safety and efficacy of mechanical thrombectomy in patients with atrial fibrillation complicated with acute intracranial arterial occlusion. Methods: Fifty-eight patients with atrial fibrillation complicated with acute intracranial arterial occlusion in the intervention group of East (Endovascular Therapy for Acute ischemic Stroke Trial) were analyzed. According to the TOAST (Trial of Org 10 172 in Acute Stroke Treatment) classification, patients were divided into ICAS (Intracranial Atherosclerotic Stenosis) group and cardiogenic embolism group. Clinical characteristics, treatment methods and clinical prognosis were compared between ICAS group and cardiogenic embolism group. Results: A total of 58 patients with atrial fibrillation complicated with acute intracranial arterial occlusion were included in this study, including 46 patients in the cardiogenic embolism group (79%) and 12 patients in the ICAS group (21%). The pre-hospital transport time in ICAS group was longer than that in cardiogenic embolism group (P<0.05).Patency rate in patients with atrial fibrillation complicated with acute intracranial arterial occlusion was 98.3% (57/58), The rate of patients with the 90-day function independent (mRS 0-2) was 51.7% (30/58). There were no statistically significant differences in functional independence, mortality rate, ICH and sICH at 90 days between the cardiogenic embolism group and the ICAS group. Conclusions: Mechanical thrombectomy is an effective method to treat patients with atrial fibrillation complicated with acute intracranial arterial occlusion.
