Surgical Treatment of a Patient With Nutcracker Syndrome via Transposition of the Left Renal Vein

INTRODUCTION: Nutcracker syndrome (NCS) is caused by compression of the left renal vein (LRV) between the aorta and the superior mesenteric artery (SMA) where it passes in the fork formed at the bifurcation of these arteries. NCS leads to LRV hypertension, resulting in left flank and abdominal pain, with or without haematuria and pelvic ureteral varices. REPORT: The patient was a young female with diagnostic criteria of NCS, with severe clinical manifestations. The patient underwent transposition of the LRV approximately 3.0 cm below the original anatomic site and was anastomosed to the inferior vena cava (IVC) outside the meso-aortic compression zone. CONCLUSION: Although NCS is not as common as other clinical scenarios, it may be encountered by physicians in a variety of disciplines, and can cause substantial morbidity and mortality rates. This report addresses the surgical approach used in a particular case, as well as the possible complications and outcomes if not treated in due time.
