Aim:
to determine the frequency of the abnormal anatomical features affecting the inferior vena cava (IVC).
Material And Methods:
we performed 161 dissections of the ICV on fresh (145) or formaldehyde-injected (16) cadavers. There were 86 men and 75 women.
Results:
we found two abnormalities of the IVC: one left IVC in a woman and one double IVC in a man. These malformations can be explained by the embryology of the IVC.
Discussion:
the frequency of abnormalities of the IVC is highly variable according to the studies: Richardson (1983) found 3% for the duplication of the IVC. Other malformations have been reported: double IVC, left IVC or right IVC with azygos prolongation. We never observed such associations in our study. Left IVC could be explained by the development of the left supra-cardinal vein and by that of the left sub-cardinal and intercardinal anastomoses. Double IVC corresponds either to the development of the left supra-cardinal vein or to the persistence of the left cardinal vein or the left sub-cardinal vein.
Conclusion:
abnormalities of the ICV dysplay different anatomical features due to the complexity of the embryogenesis of this vessel; their frequency is far from being rare. Unknowing these abnormalities could lead to severe haemorrhages during surgical interventions on the retroperitoneal, cardiac or oesophageal regions.

Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.

The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the middle...
