Successful Treatment of a Ruptured Subclavian Artery Aneurysm Presenting as Hemoptysis with a Covered Stent / 전남의대학술지

ABSTRACT

An aneurysm of the subclavian artery is rare. Recently, we experienced a case of a ruptured subclavian artery aneurysm presenting as hemoptysis. The patient had experienced atypical chest discomfort, and computed tomography (CT) revealed a small aneurysm of the left subclavian artery (SCA). Hemoptysis occurred 2 weeks later. Follow-up CT showed a ruptured aneurysm at the proximal left SCA. Endovascular treatment with a graft stent was performed by bilateral arterial access with a 12-Fr introducer sheath placed via cutdown of the left axillary artery and an 8-Fr sheath in the right femoral artery. A self-expandable Viabahn covered stent measuring 13x5 mm was introduced retrogradely via the left axillary sheath and was positioned under contrast guidance with an 8-Fr JR4 guide through the femoral sheath. After the procedure, hemoptysis was not found, and the 3-month follow-up CT showed luminal patency of the left proximal SCA and considerable reduction of the hematoma.
