Abstract

A 45 year-old-man who had undergone ventricular septal defect repair during childhood presented with hoarseness. He was diagnosed as having a distal aortic arch aneurysm by using computed tomography, and was referred to our hospital for surgical treatment. The operation was performed via a 4th intercostal thoracotomy in the right lateral position. The aortic aneurysm occupied the upper pleural cavity. The aortic arch was pressed up by the aortic aneurysm, so visual identification and clamping of the proximal aorta and the left subclavian artery were extremely difficult. Extracorporeal circulation was established via the right femoral artery and vein. Aneurysmal resection and graft replacement were performed using the open proximal method and retrograde cerebral circulation. The aneurysmal wall and proximal aorta were fragile and the proximal aorta was narrow, although the distal aorta was normal. The difference in diameters between the proximal and distal aorta suggested the presence of coarctation of the aorta.

Aortic Coarctation

Aortic coarctation is a congenital condition characterized by narrowing of the aorta. Discover the latest research on this disease here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
