摘要

Objective:The objective of this study was to evaluate the feasibility and outcomes of transvenous endovascular embolization(TVE) for superficial intracranial arteriovenous malformations(AVMs).Methods:After collecting clinical and imaging data,a prospective series of 11 patients presenting with superficial AVMs were treated by endovascular embolization using a transvenous approach between November 2016 and October 2018.Results:Ten patients(90.9%) had ruptured AVMs before TVE.The mean nidus size was 3.27 ± 1.47 cm,and the median Spetzler-Martin grade was II.The rate of immediate angiographic occlusion of the AVMs was 90.9%(10/11).One patient was treated with transarterial embolization since TVE was not achieved due to an unsuccessful positioning of the microcatheter.Two patients(cases 8 and 11) suffered a intracranial hemorrhage and a cerebral infarction with encephaledema,respectively,but no procedure-related mortalities were observed.Eight patients(72.7%) were independent with a modified Rankin Score(mRS) 2 at discharge and the m RSs of all patients,which were collected 30 days postintervention,were not more than 2.The mean follow-up period was 17 months.There were no nidus recurrences during the follow-up period.Conclusions:The curative transvenous embolization of superficial AVMs seems feasible and effective while carefully monitoring for embolization-related complications.
