A Case of Abdominal Aortic Aneurysm Associated with Horseshoe Kidney / 日本心臓血管外科学会雑誌

ABSTRACT

A 69-year-old man developed abdominal aortic aneurysm (AAA) during treatment for chronic renal failure at another hospital. On admission, CT revealed infrarenal AAA associated with horseshoe kidney. The aneurysm was exposed through a transperitoneal approach, and aortoiliac reconstruction was performed preserving the renal isthmus. Two accessory renal arteries were reconstructed. Postoperatively, both reconstructed arteries were patent on angiography, and postoperative renal function was not impaired. In surgery for AAA with horseshoe kidney, preservation or reconstruction of renal feeding arteries is important to maintain renal function.
