Nutcracker syndrome.

Abstract

Nutcracker syndrome is a vascular anomaly consisting in the compression of the left renal vein between the superior mesenteric artery and the aorta. Clinical features in nut-cracker syndrome include pelvic pain, flank pain, haematuria, gonadal varices or simply asymptomatic. We are presenting two cases, one of them with macroscopic haematuria and flank pain and the other was studied for hypertension but with previous antecedents of left renal vein embolization in the setting of varicocele. We discuss the clinical presentation as well as diagnostic and therapeutic aspects related to this syndrome.
