Abstract:
Objective To evaluate the clinical effect of endovascular embolization for the treatment of cerebellar arteriouvenous malformations (AVMs) associated with aneurysm, and to discuss its technical points. Methods The clinical data of 142 patients with cerebellar AVMs were retrospectively analyzed. Of the 142 patients, 42 had concomitant aneurysms. The patients were divided into concomitant aneurysm group and without aneurysm group. Using univariate and multivariate statistical models, the patient’s gender and age, the presence or absence of hemorrhage, the lesion’s location and size, and the presence or absence of deep venous drainage were analyzed. Results A total of 61 concomitant aneurysms were detected in the 42 patients, which were located within the malformation mass (n=14) or on the feeding artery (n=47). The concomitant aneurysms located in the malformation were closely related to AVM hemorrhage and the deep venous drainage. During the follow-up period after endovascular embolization, no recurrence of bleeding was observed in all the 42 patients. Conclusion In order to reduce the relapse rate of hemorrhage, the formulation of therapeutic measures should be based on the management of the concomitant aneurysm when endovascular embolization treatment is employed for AVM associated with aneurysm.
