Ruptured Abdominal Aortic Aneurysm in A Patient with A Retroaortic LeftRenal Vein

Retroaortic left renal vein is rare but life-threatening in abdominal aortic surgery. The risk of venous injury is especially high during surgery for a ruptured Abdominal Aortic Aneurysm (AAA). We report a case of ruptured AAA in an 84-year-old woman. Careful evaluation of the preoperative contrast-enhanced Computed Tomography (CT) images showed a retroaortic left renal vein and triple left renal arteries. The patient underwent successful surgical repair. Even in cases of ruptured AAA, preoperative contrast-enhanced CT should be performed to search for venous and arterial anomalies and reduce the risk of fatal bleeding when vital condition is not critical.
