Combined endovascular embolization of large intracranial arteriovenous malformations and their subsequent surgical resection.
Twelve patients with large arteriovenous malformations (AVMs) were subjected to endovascular embolization followed by surgery. Of the 12 patients, 9 were males and 3 females. Their age ranged from 11 to 37 years. Eleven AVM nidi were more than 6 cm in diameter and one AVM, located in a crucial brain area, was 4 cm in diameter. More than 70% of the AVM masses were excised in 11 of the patients, while under 50% was excised in the remaining patient. Complete excisions of the lesions were achieved in all 12 patients 7-10 days after endovascular embolization. No new major neurological deficits occurred. The results showed that the cerebral AVMs can be effectively operated on after endovascular embolization.
