Nutcracker Phenomenon with Menorrhagia in a Woman with Marfan Syndrome.

Abstract

Nutcracker phenomenon (NCP) refers to left renal vein compression at the superior mesenteric artery origin involving hematuria and dysuria due to the compression of the renal venous return and pelvic congestion syndrome caused by the compression of the gonadal venous return. A leptosomatic woman (body mass index, 19 kg/m2) presented with NCP and Marfan syndrome accompanied by severe menorrhagia. Vascular ultrasonography revealed reversed flow in the left ovarian vein. Preoperative computed tomography revealed a sharp aortomesenteric angle and short aortomesenteric distance. After controlling her menstrual period via oral contraception, she underwent valve-sparing surgery for aortic root dilation, which spontaneously subsided the menorrhagia.
