Abstract
Purpose
Here, we describe nutcracker syndrome management using intravascular ultrasound (IVUS) during endovascular stent placement of the renal vein.
Case Report
A 60-year-old woman with a known Factor V Leiden mutation, long-standing smoking history, and family history of pancreatic cancer presented with 2 years of intermittent left upper quadrant pain (LUQ) and a 15 lb unintentional weight loss. Work-up included abdominal ultrasound (US) and abdominal computerized tomography (CT) scan. Abdominal US and Chest CT scan were negative while the abdominal CT scan revealed severe compression of the left renal vein by the superior mesenteric artery, consistent with nutcracker syndrome. Renal venogram and endovascular stent placement performed under IVUS guidance. IVUS was used to determine stent size and measure flow and assess patency after stent placement.
Conclusions
Post-renal vein stent placement, the patient had resolution of her symptoms with follow-up duplex renal ultrasound exam demonstrating restored blood flow in the left renal vein with improved patency.
