In symptomatic buttock arteriovenous malformations (AVM), embolization techniques and surgical resection are suggested treatment options. Our aim was to evaluate the feasibility and the long term results after single surgical resection.

Twelve patients underwent surgical resection without pre-operative embolization. Eleven had incomplete procedures, including nine arterial embolizations (1 to 3 years ago). All were symptomatic, and CT scans showed AVM located in the cellular spaces with preservation of gluteal muscles. Median follow-up time was 80 months. On the last follow-up CT scan, 67% had no residual AVM.

Pre-operative embolization, particularly with non-resorbable embolic material(Onyx), makes AVM resection and imaging follow-up more difficult (artifact) and should be avoided.
