Microvascular embolization of cerebral arteriovenous malformations

Abstract
A useful variation of an established technique is described for embolization of cerebral arteriovenous malformations. Silastic sponge emboli that fit into No. 16, 17 and 18 stub adapters are passed through standard-sized transfemoral catheters. Of 28 treated patients, obliteration was regarded as very successful in 16. Partial success was achieved in 4. Eight were regarded as failures because the reticulum was too large for these microemboli.
