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

ABSTRACT

Horseshoe kidney (HSK) occurs in about 0.25% of the population. Coincidence of HSK with abdominal aortic aneurysm (AAA) is rare. We describe a 70-year-old man with an infrarenal AAA coexistence with HSK diagnosed by 3D-CTA. Preoperative 3D-CT and Angiography showed two major renal arteries and an accessory artery arising from the anterior wall of aneurysm. The aneurysm was successfully replaced by knitted Dacron bifurcated graft without resection of the isthmus. The accessory renal artery was reconstructed to the graft. Renal infarction and renal dysfunction did not occur and the postoperative course was uneventful.
