Purpose: To present a case highlighting the efficacy of stent implantation for left renal vein (LRV) entrapment, otherwise known as the nutcracker phenomenon. Case Report: A 17-year-old boy presented with a history of gross hematuria and left flank pain. Magnetic resonance angiography documented compression of the LRV between the superior mesenteric artery and aorta. A Memotherm stent was successfully placed across the LRV to restore adequate luminal flow after a Wallstent failed to adequately span the narrowed segment. Spiral CT angiography at 6 months confirmed LRV patency; the patient remains asymptomatic and free of hematuria at 12 months. Conclusions: Endovascular stenting for the nutcracker phenomenon is safe and effective and may represent a valuable approach for lessening the morbidity of surgical procedures.

Abstract

Purpose: To present a case highlighting the efficacy of stent implantation for left renal vein (LRV) entrapment, otherwise known as the nutcracker phenomenon. Case Report: A 17-year-old boy presented with a history of gross hematuria and left flank pain. Magnetic resonance angiography documented compression of the LRV between the superior mesenteric artery and aorta. A Memotherm stent was successfully placed across the LRV to restore adequate luminal flow after a Wallstent failed to adequately span the narrowed segment. Spiral CT angiography at 6 months confirmed LRV patency; the patient remains asymptomatic and free of hematuria at 12 months. Conclusions: Endovascular stenting for the nutcracker phenomenon is safe and effective and may represent a valuable approach for lessening the morbidity of surgical procedures.
