Treatment of prosthetic graft infection after thoracic aorta replacement.
PURPOSE Prosthetic graft infection is a fatal complication after thoracic aorta replacement, and it is sometimes difficult to perform a prompt re-operation when the patient carries the infectious source of the graft. We evaluated the early and mid-term outcomes of aortic graft infection after thoracic aorta replacement, focusing on the timing of the surgery. METHODS This study included eight ...
متن کاملAortic Pseudo aneurysm 3 Years after Interposition Tube Graft for Acute Dissection of Ascending Aorta
Introduction: Patients with primary acute aortic dissection are at higher risk of complications, including increasing aortic aneurysm diameter, aortic rupture, aortic pseudo aneurysm, and recurrent aortic dissection. Case presentation We presented the case of a recurrent pseudo aneurysm and rupture of the aorta in the distal a...
متن کاملProsthetic replacement of the ascending aorta increases wall tension in the residual aorta.
BACKGROUND Prosthetic replacement of the ascending aorta with nonelastic vascular grafts impairs the local Windkessel function. Whether this increases wall tension in the remaining aorta is still a not completely investigated hypothesis but is of clinical relevance with respect to postprocedural development of aneurysms and dissections, especially in the proximal descending aorta. METHODS Fre...
متن کاملEndovascular Repair of the Aortic Arch and Ascending Thoracic Aorta
Background The aortic arch is wide, compliant, and mobile. Its flow rate is high and its branches supply an organ, the brain, with no tolerance for ischemia. In this location, an endovascular stent graft is difficult to deliver, difficult to secure, and prone to fatigue fracture, graft erosion, or migration. The only advantage is the opportunity for downstream access to vital arterial branches,...
متن کاملAortic coarctation misdiagnosed as a descending thoracic aorta aneurysm.
Aortic coarctation (AC) represents -7% of congenital cardiac diseases and is usually diagnosed in childhood or early adult Life, depending on the severity of obstruction and associated malformations. Left untreated fewer than 20% of patients survive to age 50. We describe a case of thoracic AC, diagnosed at age 61, in a woman with known hypertension since age 45. At age 56 the patient was admit...
