Left Renal Vein Anatomical Anomalies: Radiological and Surgical Implications

Abstract

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 these relatively uncommon but hazardous conditions, which should be familiar to anatomists, radiologists and surgeons.
