Intrathoracic Aneurysm of the Right Subclavian Artery

Abstract

Arterial aneurysms may occur in all arteries of the human body. Arteriosclerosis takes the first place in the aetiology of the aneurysms of the great arteries and lower extremities. We would like to present a rare atherosclerotic aneurysm in the intrathoracic region of the right subclavian artery, in which vascular continuity was re-established by resection and direct end-to-end anastomosis instead of the generally used resection + revascularization technique with vascular grafts.

Proximal Humerus Destruction due to Axillary Artery Aneurysm: A Case Report

“…Axillary artery aneurysms can cause vascular or neurologic complications and can mimic an abscess-like lesion as in our case. Sometimes, axillary artery aneurysm is seen as intra-thoracic masses in the chest x-ray, which can be differentiated from the tumors of the chest and lungs [9,10]. Due to the lethal nature of arterial aneurysm, irreversible complications can be prevented with accurate diagnosis and early treatment.…”

Subclavian and axillary arterial aneurysms: two case reports

“…Surgical access to intrathoracic aneurysms of the subclavian artery depends on which side the aneurysm is. For aneurysms of the left subclavian artery, a left-side thoracotomy is used, whereas for aneurysms of the right subclavian, the need for better control of the ascending aorta and of the aneurysm's necks means that sternotomy is recommended, with or without a supraclavicular incision, and the sternoclavicular joint may or may not be disarticulated 1,4,5 . The incision most often described in relation to cases of extrathoracic aneurysms of the subclavian artery is a supraclavicular access, although there are also reports of combination supraclavicular and infraclavicular incisions or cervicotomy, depending on the peculiarities of each patient 1,3,4 .…”

“…When these aneurysms emerge in the more distal segments of this artery or in the axillary artery, they may be associated with thoracic outlet syndrome 1,3,4 . Aneurysms in this territory can also be posttraumatic; infectious; associated with coarctation of the aorta; congenital; or related to Marfan syndrome and cystic necrosis of the tunica media 1,5,6 . When diagnosed, the literature recommends that aneurysms of the subclavian-axillary segment should be treated surgically, because of the risk of ischemic complications secondary to thromboembolic phenomena in upper extremities and in the carotid-vertebral territory, due to the possibility of retrograde embolization 1,4,7 .…”
