Endovascular Treatment of a Distal Aneurysm of the Superior Cerebellar Artery by Intra-Aneurysmal Injection of Glue

Abstract

Aneurysms in the distal cerebellar arteries are rare events. They are associated with a poor prognosis, as surgery or embolisation with Guglielmi detachable coils (GDCs) is very difficult. The ability to treat them surgically depends on the location of the aneurysm, but surgery is considered difficult and is associated with a high morbidity/mortality rate. Embolisation with GDCs may be difficult or impossible because of the distal location of the aneurysm or the unfavourable ratio between the size of the aneurysm and the size of the parent vessel. We report our experience in one case treated with intra-aneurysmal injection of glue. The aneurysm, located in the distal right superior cerebellar artery, was catheterized with a flow-guided microcatheter, and glue was slowly injected into the aneurysmal sac. The treatment resulted in total occlusion of the aneurysm with preservation of the parent artery.
