Endovascular treatment of intracranial aneurysms with intrasaccular balloon remodeling technique

Abstract

Objective – to study the effectiveness of using intrasaccular balloon remodeling technique (BRT) when you turn off the endovascular cerebral arterial aneurysms (AA) complex shape of the brain vessels. Materials and methods. We analyze the results of endovascular off AA using intrasaccular BRT in 11 patients with 11 aneurysms. Men were 6 (54.5 %), women – 5 (45.5 %). In 3 (27.3 %) cases aneurysm had size of 4-5 mm, in 6 (54.5 %) – 6-10 mm, in 2 (18.2 %) – 11-15 mm. In 3 (27.3 %) patients we used Scepter cylinder, in 8 (72,7 %) – HyperForm™. In two cases by using Scepter balloon occlusion of the aneurysm coils carried by the balloon lumen. Results. Through the use of intrasaccular BRT we were able to achieve the following results: 1 type of off scale Raymond-Roy – 3 (27.3 %) case, type 2 – 4 (36.4 %), type 3a – 4 (36.4 %). At follow-up examination type 1 is established in 7 (63.6 %) patients, type 2 – in 2 (18.2 %), type 3 – in 2 (18.2 %). Ischemic complications were observed in 1 (9.1 %) case. At the time of patient discharge was observed complete regression of neurological deficit. Deaths were not in this observation. Conclusions. Using intrasaccular balloon remodeling technique expands the indications for endovascular shut down AA cerebrovascular complex form. The risk of ischemic events is comparable to that of using unassisted coiling.
