Endovascular management of recurrent stenosis following left renal vein transposition for the treatment of Nutcracker syndrome

Nutcracker syndrome is an entity resulting from left renal vein compression by the superior mesenteric artery and the aorta, leading to symptoms of left flank pain and hematuria. Conventional treatment has been surgical, commonly through transposition of the left renal vein to a more caudal location on the inferior vena cava. Additionally, endovascular approaches, primarily via renal vein stenting, have been described for treatment of this syndrome. We report the case of a patient with Nutcracker syndrome who underwent successful left renal vein transposition but then developed recurrent symptoms 10 months postoperatively and was successfully treated with angioplasty and stenting.
