Juncture and method choice of cerebral arteriovenous malformations treatment

Objective To discuss juncture and method choice of cerebral arteriovenous malformation(AVM treatment including microsurgery endovascular embolization and Gamma knife. Methods Aanalysis has been made in 63 patients with cerebral AVM 50 cases were operated on and most were completed under microscopy 8 patients whose AVMs were located in main functional areas were treated by endovascular embolization and 4 by Gamma knife. Results Total AVM excision were accomplished in 44 cases subtotal excision in 6 cases. In cases of embolism disappearance of AVM nidus in 3 cases and reduction of 50% in 5 cases. In cases treated by Gamma knife it showed that AVM nidus became light and shrunk. All cases were followed up ranging from 3 months to 9 years. Excellent or good results were achieved in 41 patients 65.1%).After operation 3 patients died 4.8%.Conclusions Microsurgery is main therapy to AVM. In large and complex AVM combination of embolization and resection is relatively a good plan. In patients with small AVM and located in deep or functional areas which were unsuitable for resection or embolization Gamma knife is better indicated.
