Prosthetic left renocaval bypass for posterior nutcracker syndrome.

A 58-year-old man presented with severe hematuria of unknown origin and intermittent left flank pain for 8 months, and he was diagnosed with posterior nutcracker syndrome. He underwent prosthetic left renocaval bypass with complete resolution of symptoms. Computed tomography showed a functional graft between the left renal vein and caval vein. This technique is a feasible choice for surgical treatment of posterior nutcracker syndrome with satisfactory results.
