Abstract：Objective To explore the efficacy and safety of microsurgery and endovascular interventional embolization for treating intracranial arteriovenous malformation (AVM).Methods A total of 53 AVM patients underwent microsurgery (N =27) and endovascular interventional embolization (N =26).Postoperative DSA revealed the resection of malformed vessels and embolization.Surgery-related complications were recorded,and Glasgow Outcome Scale (GOS) was used to evaluate the prognosis one month after operation.Results In microsurgery group,postoperative re-examination revealed complete resection in 26 out of 27 cases,with the cure rate of 96.30％ (26/27).After operation,limb movement disorder occurred in 2 cases (7.41％),neurological dysfunction occurred in one case (3.70％) and status epilepticus (SE) occurred in one case (3.70％).The occurrence rate of postoperative complications was 14.81％ (4/27).One month after operation,GOS showed 5 score in 15 cases (55.56％),4 score in 10 cases (37.03％) and 3 score in 2 cases (7.41％).The rate of good prognosis was 92.59％ (25/27).In endovascular interventional embolization group,postoperative re-examination revealed complete embolization in 8 out of 26 cases,with the cure rate of 30.77％ (8/26).After operation,limb movement disorder occurred in 2 cases (7.69％) and neurological dysfunction occurred in 2 cases (7.69％).The occurrence rate of postoperative complications was 15.38％ (4/26).One month after operation,GOS showed 5 score in 17 cases (65.38％),4 in 7 cases (26.92％) and 3 in 2 cases (7.69％).The rate of good prognosis was 92.31％ (24/26).Conclusions Microsurgery is a safe and effective treatment for intracranial AVM.Endovascular interventional embolization can also achieve good curative effect for patients with intracranial AVM under Puerto Rico scale ≤ 3 score.Multiple and staged embolization or embolization combined with radiotherapy can effectively relieve symptoms and improve prognosis for patients with complex intracranial AVM.
