Abstract

The Nutcracker syndrome refers to compression of the left renal vein between the aorta and the superior mesenteric artery, associated with hematuria, abdominal pain, and varicocele formation. We report a 13-year-old boy with intermittent gross hematuria for 14 months before admission. Ultrasonography shows narrowing of proximal left renal- vein and dilatation of distal left renal vein at the point of superior mesenteric artery and aorta. Intravenous digital subtraction angiography shows localized indentation of the distal portion of left renal vein and retrograde filling of adrenal vein and gonadal vein as collateral circulations. The pressure gradient between the proximal renal vein and the inferior vena cava was over 10 rnrnHg.
