LEFT RENAL VEIN ANATOMICAL ANOMALIES : RADIOLOGICAL AND SURGICAL IMPLICATIONS

Objective:To emphasize the incidence and clinical, diagnostic and surgical implications of left renal vein developmental anomalies.Design:Retrospective analysis of case notes.Setting:Clinical Anatomy Department and Surgery Department, Faculty of Medicine, University of Valencia, Spain.Patients, participants:Standard radiological examinations (CT scan) performed on 745 patients; surgical findings at operation in 128 patients with aorto-iliac atherosclerotic disease, and 72 donor cadavers for transplantation.Main outcome measures:Incidence of left renal vein anomalies (retro-aortic left renal vein and peri-aortic renal venous collar), based on radiological (CT scan) and surgical observations. Analysis of implications to surgical management.Results:The radiological series disclosed a 2.68% incidence of left renal vein anomalies: 1.33% retroaortic left renal vein, and 1.33% peri-aortic renal venous collar. The surgical series showed a 1.5% incidence of both anomalies.Conclusions:The importance is stressed of ...
