Demonstrates successful surgical management of a large 7.5 cm left subclavian artery aneurysm involving the aortic arch using vascular transposition and pericardial patch reconstruction under hypothermic circulatory arrest.
A 74-year-old man suffered from hoarseness and a sensation of a globus pharyngeous, caused by a left SAA with a diameter of 7.5 cm. The aneurysm and its thrombus arose from a broad neck at the aortic arch (Fig. 1(a)) and was causing compression of the trachea and oesophagus (Fig. 1(b)). Surgical intervention consisted of a transposition of the subclavian artery (PTFE bypass) and of the vertebral artery (direct anastomosis) to the left carotid artery. Under extracorporal circulation and hypothermic circulatory arrest (24 min), the subclavian artery was transected at its origin and the aortic arch reconstructed with a pericardial patch. The postoperative course was uneventful.

Gürke et al. (2004) conducted a case report in Left subclavian artery aneurysm (7.5 cm diameter) (n=1). Surgical transposition of the subclavian artery (PTFE bypass) and vertebral artery (direct anastomosis) to the left carotid artery, with aortic arch reconstruction using a pericardial patch under hypothermic circulatory arrest was evaluated on Postoperative clinical course.
