Kidney autotransplantation for multiple renal artery aneurysms: A case report

Abstract

Kidney artery aneurysms are a rare phenomenon with a prevalence of 0.01%-1% in the general population. Although historical series describe rupture rates of 14% to 30% with a mortality rate of 80%, the natural history of kidney artery aneurysms is currently characterized by a low risk of rupture and a slow to nonexistent growth rate. Criteria for repair have been controversial for decades and currently include aneurysm size > 2 cm, female sex, and symptoms such as drug-refractory hypertension, pain, and hematuria. In this article, we report a successful kidney autotransplantation for multiple renal artery aneurysms (8 to 9 mm) in a 37-year-old woman who had suffered from arterial hypertension for 19 years. The clinical case described demonstrates the efficacy of surgical treatment of renal artery aneurysms with malignant hypertension.
