Ex Situ Repair of Pre-Hilar Aneurysmal Lesion of the Renal Artery

Renal artery aneurysms (RAAs) are rare. They are often identied incidentally during abdominal computed tomography (CT) screening for other diseases. They are occasionally identied as a rare abdominal emergency due to rupture of a left renal artery aneurysm. In recent years, endovascular therapy such as coil embolization or stentgraft with the coil embolization was successful for treating RAAs, but complex AAs may require aneurysmectomy and renal artery reconstruction by in-situ repair or ex-vivo.
