Abstract
Objective: To Investigate the efficacy of endovascular embolization of cerebral arteriovenous malformations with non balloon microcatheters. Methods:The feeding arteries of cerebral arteriovenous malformations were selectively embolized with Seldinger and microcatheter techniques. Results: The successful rate of embolism technique is 97.5%. The AVM disappeared in 11 cases and the patients recovered completely. Most of the AVM disappeared and the size of AVM reduced over 80% in 4 cases. The size of AVM reduced by 50 80% in 14 cases, and less than 50% in 9 cases. All patients were followed up for 6 months to 5 years with satisfactory results. Conclusion: Endovascular embolization therapy cerebral arteriovenous malformations with Non balloon microcatheters is accurate, safe and effective.
