Infrarenal abdominal aorta aneurysm: a rare cause of anterior nutcracker syndrome with associated pelvic congestion.

We present a rare case of anterior nutcracker syndrome caused by an abdominal aorta aneurysm (AAA). A 61-year-old woman was admitted to our institution for computed tomography angiography. It revealed an AAA 51 mm in diameter that was lifting off of the left renal vein toward the superior mesenteric artery, causing anterior nutcracker syndrome with consequent left renal vein compression and left ovarian vein congestion. Aneurysm resection was performed, followed by left ovarian vein ligation and left adnexectomy to prevent vein conglomerate rupture. This is the first case that describes anterior nutcracker syndrome caused by AAA, which was successfully treated by aneurysm resection.
