Abstract

Surgical treatment of pararenal aortic aneurysms, if compared to open repair of infrarenal aneurysms, is characterized by more technical difficulties and haemodynamic problems. Since endovascular repair has become feasible in most cases of infrarenal aneurysms, surgical treatment of pararenal aneurysms is a matter of great interest for vascular surgery. Detection of pararenal aneurysms needs a careful preoperative diagnosis, assessment of cardiac, renal and pulmonary status of the patient and planning of the surgical intervention. The surgeon needs to face an extended proximal aorta exposure, to manage the left renal vein and to choose an appropriate clamping site. Then a skilled and quick reconstruction of the visceral arteries is fundamental to minimize organ disfunction. Coupled intraoperative selective perfusion of visceral arteries and systemic administration of nephroprotective drugs optimizes organ protection during ischemia. To better define challenges, risks and results, we reviewed our experience with the treatment of pararenal aortic aneurysms. In the period between January 1993 and May 2003, 98 consecutive patients underwent surgery for pararenal aneurysms at our Institution. We treated 98 pararenal aneurysms, divid...Continue Reading

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.

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.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
