Stent-Assisted Embolization of Wide-Neck Anterior Communicating Artery Aneurysms: Review of 21 Consecutive Cases

Abstract

BACKGROUND AND PURPOSE:Anterior communicating artery (AcomA) aneurysm is the most frequent form of aneurysm. Stent placement is particularly difficult and of limited use for AcomA aneurysms. We report our experience with stent-assisted embolization for wide-neck AcomA aneurysms in 21 patients. Particular attention is given to the morphologic characteristics and strategy of stent deployment.

Feasibility and Efficacy of Endovascular Therapy for Ruptured Distal Anterior Cerebral Artery Aneurysms

“…However, the small caliber of ACA and the distal location of the aneurysm increase the risk of the parent artery injury and intraprocedural aneurysm rupture. Although the low profile self-expanding stents allowed stent-assisted coiling of the aneurysms located on the small and distal cerebral vessels, 6,29) there are the risks of in-stent thrombosis and stent malpositioning.…”

Endovascular Treatment of Wide-Neck Middle Cerebral Artery Aneurysms with Stents: A Review of 16 Cases

“…However, in the acute or subacute phase of patients with ruptured MCA aneurysms, there was moderate-to-severe vasospasm, which might lead us to inappropriate selection of undersized stents. 20 In this series, the most frequently used diameter of stents was 3.5 mm, and the minimal diameter was 2.5 mm, even in the vessel with a diameter of 0.9 mm.…”

Vascular Geometry Change Because of Endovascular Stent Placement for Anterior Communicating Artery Aneurysms

“…This technique refers to a procedure where the stent is placed partially into the aneurysm and into the afferent artery, and then the portion of the stent protruding into the aneurysm fundus provides neck support for the subsequent successful coiling. 8 Patients with severe vasospasm (Ͼ50% luminal narrowing, which is related to subarachnoid hemorrhage) of A1 and A2 segments also were excluded.…”
