A Rare Anomaly of the Left Renal Vein in the Laboratory of Anatomy of Bamako (Mali)

Abstract

Aim: The purpose of this work was to describe the left renal retro-aortic vein. Methodology: A case of left renal retro-aortic vein was discovered on a corpse of male, 45-year-old adult during the dissections to the laboratory of anatomy of the Faculty of Medicine of Bamako. The way at first was a xypho-pubic median and two side abdominal sections under costal and inguinal. The side sections under costal went of the median section to sides by following the costal edge. The inguinal side sections went of the median section to the anterior and superior iliac thorns. The abdominal wall was opened and reclined by every quoted. The small intestine and the colonist were resected with their meso. The renal pedicle was dissected on each side. The abdominal aorta and the inferior vena cava were dissected by the diaphragm up to the headland. Arteries and iliac veins were also dissected. Results: On male corpse, 45 years old, we discovered a left renal retro-aortic vein in horizontal route, and the trunk of the left renal vein was formed by the confluence of three veins at the level of the left renal hilum. The left renal vein passed almost horizontally below the left renal artery. It passed then behind the abdominal aorta to end in the inferior vena cava at the level of its left side face. The right renal vein had a normal aspect. Conclusion: The left renal retro-aortic vein is one of the variants of the anomalies of the system cellar inferior. The left renal retro-aortic vein could be responsible for renal aplasia.
