Single-session Curative Embolization of Unruptured Cerebellar Arteriovenous Malformation with Precipitating Hydrophobic Injectable Liquid

Abstract

Microsurgery is the treatment of choice for cerebellar arteriovenous malformations (AVMs). Nevertheless, endovascular therapy aims to be an effective treatment since the introduction of new embolic agents. Cerebellar AVMs represent a subgroup of vascular lesions with a high rate of hemorrhagic presentation compared with their cerebral counterpart. Moreover, they have a higher incidence of flow-related aneurysms when diagnosed. With this in mind, prompt treatment must be performed to avoid rebleeding with devastating consequences. Herein, we present the case of an unruptured cerebellar AVM treated with precipitating hydrophobic injectable liquid (PHIL) with complete obliteration.
