Background:
The venous anatomy is highly variable. This is due to possible venous malformations (minor truncular forms) occurring during the late development of the embryo that produce several anatomical variations in the number and caliber of the main venous femoral trunks at the thigh level. Our aim was to study the prevalence of the different anatomical variations of the femoral vein at the thigh level.
Methods:
This study used 336 limbs of 118 fresh, nonembalmed cadavers. The technique included washing of the whole venous system, latex injection, anatomical dissection, and then painting of the veins.
Results:
The modal anatomy of the femoral vein was found in 308 of 336 limbs (88%). Truncular malformations were found in 28 of 336 limbs (12%); unitruncular configurations in 3% (axo femoral trunk [1%] and deep femoral trunk [2%]). Bitruncular configurations were found in 9% (bifidity of the femoral vein [2%], femoral vein with axio-femoral trunk [5%], and femoral vein with deep femoral trunk [2%]).
Conclusion:
Truncular venous malformations of the femoral vein are not rare (12%). Their knowledge is important for the investigation of the venous network, particularly the venous mapping of patients with cardiovascular disease. It is also important to recognize a bitruncular configuration to avoid potential errors for the diagnosis of deep venous thrombosis of the femoral vein, in the case of an occluded duplicated trunk.

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...
