Analysis of renal artery geometry may assist in the design of new stents for endovascular aortic aneurysm repair

Abstract

Endovascular repair of infrarenal aortic aneurysms is a feasible technique, but up to 30 per cent of patients may be excluded on the basis of a short proximal aortic neck. A dissection study was performed on 65 cadavers to measure the distance between the superior mesenteric and renal artery ostia, and to document the points of origin of the renal arteries. The interostial distance did not differ significantly between aneurysmal and non-aneurysmal aortas (P = 0.90 for the left renal artery; P = 0.72 for the right). The median distance was 0.7 cm. The renal arteries originated between 2 and 4 o'clock on the left and between 9 and 10 o'clock on the right. The relative consistency of the anatomy in this region may allow the development of a new stent which would increase the number of patients suitable for endovascular repair.

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.
