Abstract

To discuss the feasibility of endoluminal stent-grafting for descending thoracic aortic lesions. 12 patients underwent stent-grafting of the thoracic aorta with Talent (11 patients) and Vanguard (1) device. Endovascular technique was used in 12 patients with descending thoracic aortic aneurysms (5 patients), Stanford B dissections (6), and pseudoaneurysm (1). 13 straight stent-grafts were inserted through 18-24 F theaths via a femoral arteriotomy under local (2 patients) or general (10) anesthesia. The procedure was technically successful in all patients without aneurysm rupture, paraplegia, and organs or limbs ischemia. There were 3 early endoleaks. Follow-up showed that 4 of 5 aortic aneurysms were excluded completely and one endoleak was changed into persistent. Four entries of 6 patients with stanford B dissection were excluded and 2 early endoleaks were sealed during one month after operation. Four false lumen were filled completely and 2 false lumen were filled partly by thrombosis. Descending thoracic aortic stent-grafting is a safe, highly successful and feasible alternative to conventional surgery. The long-term result remains unclear, especially that of the endovascular repair of Stanford B dissection.

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.
