Direct Revascularization with Autotransplant Technique for a True Aneurysm of the Renal Artery 20 Years after Kidney Transplantation

Annals of Vascular Surgery

Abstract

True degenerative aneurysm of renal artery represents a very rare evolution in kidney transplantation. The cases presented in the literature are usually perianastomotic or mycotic pseudoaneurysm related to surgical technical defects or local infections. Herewith, we present the case of a voluminous true aneurysm developed in a young patient transplanted at our hospital 20 years before. All follow-up ultrasounds were always normal until the last disclosing a voluminous aneurysm of the transplanted renal artery. The subsequent angio-CT-scan confirmed the presence of a 52-mm saccular dilatation of the renal artery. For the complex anatomy, the endovascular approach was excluded, and a surgical revascularization was staged. We treated this lesion with the autotransplant technique, preserving the transplanted kidney, resecting the aneurysm, and performing a direct anastomosis after cold perfusion of the kidney. The autotransplant technique demonstrated to be a safe and effective approach in this challenging and very unusual situation.

Aneurysm

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

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

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.
