“…Obstruction or thrombosis of the renal vein caused by nutcracker phenomenon and portal hypertension are thought to induce secondary renal varices. [3][4][5] However, since obstruction of the renal vein was not observed in this patient and she had no previous history of portal hypertension, the diagnosis was idiopathic renal varices.…”

“…It has been reported that renal varices is a rare disease, and in a broad sense, renal varices including extrarenal varices, such as periureteric varices, constitute approximately 2.5 to 15% of disease with symptoms such as hematuria unexplained prior to angiography. 1,4 However, the prevalence of intra-renal varices is extremely low. 2 Although renal varices have been divided into idiopathic and secondary types, most are idiopathic.…”

“…Compression of the left renal vein (LRV) between the superior mesenteric artery and the abdominal aorta in the aorto-mesenteric angle has been implicated as a cause of occult left glomerular hematuria, periureteral and gonadal varices, and varicocele in children and adults [1][2][3][4]. Bleeding is thought to be secondary to left renal vein hypertension and has been reported with and without angiographically demonstrable varices [3,[5][6][7].…”

“Dilatation” of the left renal vein on computed tomography in children: A normal variant

Compression of the left renal vein (LRV) between the superior mesenteric artery and the aorta is thought to be a cause of hematuria, periureteral and gonadal varices, and varicocele ("Nutcracker phenomenon"). Previous investigators have suggested that this diagnosis can be made on computed tomography when the LRV ratio greater than or equal to 1.5 (the diameter of the LRV proximal to the aorto-mesenteric angle divided by the diameter of the LRV distal to the aorto-mesenteric angle). This study was designed to establish the normal range for the LRV ratio on CT in children. The LRV ratio was measured in thirty-nine consecutive children undergoing intravenously enhanced CT of the abdomen. None of the children had hematuria on urinalysis immediately before or after the CT. Children with any known abnormality involving the kidneys, adrenal glands, IVC, or renal or gonadal veins were excluded. The patients ranged in age from 3.4 to 18.5 years (mean = 10.6 years). LRV ratio ranged from 0.78 to 2.00 (mean = 1.46; S.D. = 0.312). Twenty of the 39 children (51.3%) had a LRV ratio greater than or equal to 1.50. The conclusion is that the normal range for the LRV ration is too wide for it to be useful in diagnosing LRV entrapment and that a LRV ratio greater than or equal to 1.5 on CT is normal in children.
