A Case of Nutcracker Syndrome Due to a Huge Abdominal Aortic Aneurysm

Abstract

The Nutcracker syndrome is a rare condition that the left renal vein becomes compressed most commonly between the aorta and the superior mesenteric artery. We report here a case of Nutcracker syndrome due to a huge abdominal aortic aneurysm. A 77-years old man with protein and blood in his urine, presented to our hospital. Computed tomography(CT) image demonstrated the abdominal aortic aneurysm measuring 93 mm×82 mm, the Nutcracker phenomenon and the left testicular varicose veins. We performed Y-grafting following resection of the abdominal aortic aneurysm. When the aneurysm was resected, the compression of the left renal vein was released. CT image after the operation revealed that the testicular varicose veins were disappeared and the compression of the left renal vein was reduced. He was discharged on postoperative day 22. Now his hematuria is changing for the better at his follow-up.
