Abstract:
Objective To study the risk factors of intracranial hemorrhage after endovascular therapy of cere-bral arteriovenous malformations embolization.Methods the clinical records and images of 230 patients with cAVMs were retrospectively reviewed.Patients with intracranial hemorrhage after endovascular therapy in 3 days were recorded and the risk factors of hemorrthage by using multivariate logistic regression for guiding the treatment strategy were studied.Results There were 15 patients occurred intracerebral hemorrhages.After treatment the area of cAVMs was significantly smaller than that before treatment[(2.18 ±0.91)cm vs (6.67 ±1.56)cm],the difference lvas a statis-tically significant (t =9.627,P <0.05).A partial AVM reduction of ≥36.5%(P =0.031)and hypertension(P =0.025)were considered as risk factors for hemorrhage after endovascular therapy of cAVWs.Conclusion Patients receives a partial AVMreduction of ≥36.5% or with hypertension history have a tendancy of increasing hemorrhage after endovascular therapy of cAVMs.It's helpful for preventing intracerebral hemorrhage if the arterial blood pressure maintains after endovascular therapy.
