Saphenous Bypass for Treating Anterior Nutcracker Syndrome After Failed Renal Vein Transposition: A Case Report.

AimTo report on a case of renal vein anterior nutcracker syndrome (ANCS) that was treated using saphenous vein bypass after a failed attempt of renal vein transposition.CaseA 42-year-old female presented with gross hematuria and flank pain. Computed tomography revealed a left renal vein (LRV) anterior nutcracker syndrome. An attempt to perform LRV transposition failed due to short vein length. A saphenous bypass was then harvested to perform a bypass between the inferior vena cava and LRV. At 6-month follow-up, the patient remained symptom-free, and imaging confirmed graft patency.ConclusionSaphenous vein bypass presents a viable option in patients with short renal vein or failed renal vein transposition in cases of ANCS.
