Endovascular Treatment of Intracranial Ophthalmic Segment Aneurysms: A Series and Literature Review.

Aim: To present the outcomes and follow-up results of endovascular coil embolization in patients with ophthalmic segment aneurysms (OSAs).

Material And Methods: The data of 42 patients with 44 OSAs (7 ruptured and 37 unruptured), who underwent treatment using endovascular techniques between January 2007 and November 2010, were retrospectively reviewed.

Results: The angiographic occlusion of the aneurysms was complete for 37 aneurysms (84.

A combined bilateral approach to anterior communicating artery aneurysm.

Aim: To discuss the features, feasibility, and safety of a combined bilateral approach in the endovascular treatment of intracranial anterior communicating artery (ACoA) aneurysm.

Material And Methods: We performed a retrospective analysis of the clinical data of patients with ACoA aneurysm treated with a combined bilateral approach.

Results: We successfully embolized aneurysms in nine patients with intracranial ACoA aneurysm using a combined bilateral approach.

Stent placement to treat ruptured vertebral dissecting aneurysms.

Conventional endovascular treatment may have limitations for vertebral dissecting aneurysm involving the origin of the posterior inferior cerebellar artery (PICA). We report our experiences of treating vertebral dissecting aneurysm with PICA origin involvement by placing a stent from the distal vertebral artery (VA) to the PICA to save the patency of the PICA. Stenting from the distal VA to the PICA was attempted to treat ruptured VA dissecting aneurysm involving the PICA origin with sufficient contralateral VA in eight patients.

Stent-jail technique in endovascular treatment of wide-necked aneurysm.

Aim: To describe a reconstructive technique using single stent for wide-necked aneurysms.

Material And Methods: This technique was described as stent-jail technique consisting of the aneurismal catheterization before the deployment of a self-expandable stent across the aneurysm neck. Following the deployment of the stent, embolization coils were delivered with the microcatheter positioned within the aneurysm dome and wedged between the stent and the aneurysm dome.
