Surgical Treatment for Deep-Seated or Large AVMs
Excluding patients with primarily durai or intraorbital arteriovenous malformations (AVMs), our experience over the past 25 years includes approximately 480 patients with AVMs, primarily in the brain. The size distribution of these is approximately as follows: 50% were 3 cm or less, 20% were 4 cm, 15% were 5 cm, 10% were 6 cm, and 5% were greater than 6 cm. This distribution is probably tilted toward larger AVMs because many of our patients were referred when their lesions was considered not amenable to surgical excision.
