Successful combination therapy with parallel stent-graft placement and coil embolization for a treatment of a fusiform brachiocephalic artery aneurysm: a case report

Abstract

Purpose: Development of a novel interventional approach for treatment of a fusiform brachiocephalic artery aneurysm in a patient for whom direct surgery could not be performed due to a systemic complication. Methods: As the distal side of the aneurysm involved both the common carotid and subclavian arteries, a combination of parallel stenting and coil embolization was used to avoid disturbing the blood fl ow in each artery. Result: Successful endovascular obliteration of the aneurysm was achieved with preservation of the common carotid and subclavian arteries without any ischemic complications. Conclusion: To our knowledge, this is the fi rst report describing combined use of coil embolization and parallel stenting for treatment of a fusiform brachiocephalic artery aneurysm. This therapeutic approach is an excellent alternative that should be considered as a treatment option for this type of aneurysm.

Successful Balloon-assisted Coil Embolization of Right Subclavian Artery Aneurysm: A Case Report

“…Endovascular surgery by stent-assisted coil embolization has also been reported. [2][3][4] Reports on subclavian artery aneurysms after 2018 are shown in Table 1. 3,[13][14][15][16][17][18][19][20][21][22] Treatment methods consisted of open surgery in 25 patients, endovascular treatment in 13, and their combination in 3.…”

“…Parent artery-preserving endovascular treatment methods for aneurysms include covered stenting such as stent grafting, coil embolization, and stenting alone. 4) Coil embolization procedures include embolization with a coil alone, balloon-assisted coil embolization, and stent-assisted coil embolization. Based on the site, shape, and characteristics of aneurysms, an optimal method is selected.…”

“… 1) Most of the subclavian artery aneurysms have been treated by open surgery or endovascular treatment using a stent graft. 2 , 3) A case report of stent-assisted coil embolization was previously published, 4) but to the best of our knowledge, no study has reported balloon-assisted coil embolization of subclavian artery aneurysms. In this article, we report a case of unruptured right subclavian artery aneurysm successfully treated using balloon-assisted coil embolization.…”
