Abstract
BACKGROUND AND PURPOSE: Herein, we report our initial experience with the endovascular management of cerebral arteriovenous malformations (AVMs) using the liquid embolic agent Onyx and n-butyl cyanoacrylate for AVM embolization. METHODS: We reviewed data from 15 patients with brain AVMs, who were observed at our endovascular facility from January 2008 to July 2011. All cases were embolized with Onyx and/or n-butyl cyanoacrylate. There were 8 women and 7 men with a mean age of 27.2 years (range 17-43 years). The clinical presentations included intracerebral haemorrhage (n = 7), seizures (n = 4), headache (n = 2), and focal neurological deficits (n = 2); according to the Spetzler-Martin classification (Spetzler R and Martin N (1986) J NeurosurgV65 446-83), 8 AVMs were grades I-II, 5 were grade III, and 2 were grades IV-V. RESULTS: A total of 31 embolization procedures were performed in 15 patients, and 44 feeding pedicles were embolized, ranging from 1 to 5 per patient, with an average size reduction of 70% (median 75%, range 40-100%). Total obliteration was achieved for 3 AVMs (20%) (2 patients had single feeders and 1 patient had double feeders), and a partial embolization was achieved in 12 patients (80%). The procedure was related to a permanent disabling morbidity in one patient (6.6%), and no mortalities occurred. CONCLUSIONS: The outcome of (AVM) embolization in our centre is comparable to the reported outcome in other larger-volume centres. The feasibility and safety of AVM embolization in our low-volume centre are similar to the outcomes reported at high-volume centre.
