A pararenal aneurysm is a rare type of an abdominal aortic aneurysm. The authors report 25 cases out of 429 abdominal aneurysms. The diagnosis was based on a CT-scan and subsequent biplane arteriography. The most common type was the dorsal proximal aortic dilatation, involving the origin of 1 or 2 renal arteries. A retroperitoneal approach was used in 18 of the 25 patients. The most common complication was the retroperitoneal hemorrhage, necessitating reintervention. None of these patients died or developed renal insufficiency despite a suprarenal clamping during the proximal reconstruction.
