Nutcracker Syndrome in Siblings

ABSTRACT

Nutcracker syndrome refers to the compression of the left renal vein between the abdominal aorta and superior mesenteric artery which can lead to renal vein hypertension. Patients can present with hematuria, proteinuria, dysuria or abdominal pain. In diagnosing the nutcracker syndrome, measurement of the peak velocity ratio of aorto-mesenteric border versus renal hilum by Doppler sonography is useful. Currently, there are few reports about the genetic correlation in this syndrome. We report two cases of the nutcracker syndrome found in male siblings with hematuria.
