Objectives: Assessing the difficulties in microsurgical treatment of cerebral haemorrhage due to ruprured arteriovenous malformation (AVM). Methods: This study performed on 115 patients admitted at two hospitals (Viet-Duc and Bach Mai) between 1/2011 aCId 1/2014. Results: Female/male:1/1.8. Mean age 24.6. Site of AVM: 33 percent of AVM at level of temporal regions; 24.3 percent at frontal site. According to Spetzler, 85.2 percent of patient were at 1-2 grade. At the moment of operation, 46.1 percent of patient were consciousness, 18.3 percent in coma. Difficult factors realized in operation included 13.9 percent large AVM, 18.3 percent located in eloquent zone and deep site, 12.2 percent peroperation swelling, 9.6 percent intraruptured AVM, 24.3 percent difficult determination between feeding arteries and drainage veins. Conclusions: Peroperation difficulties in microsurgery treatment of ruptured AVM included large AVM, location in eloquent zone and deep site, peroperation swelling, intraruptured AVM, difficult determination between feeding arteries and drainage veins.
