Abstract
An unusual variation of the iliac veins was detected by computed tomography (CT) angiography in a 35-year-old man. In coronal CT reconstructions, it was shown that the right internal iliac vein of this patient crossed to the left side and drained to the left common iliac vein. This variation is important in retroperitoneal, laparoscopic and orthopedic surgery. We present the CT findings and discuss the embryological origin of this unusual congenital anomaly.
Résumé
Une variation inhabituelle des veines iliaques a été découverte par tomodensitométrie chez un malade de 35 ans. Les reconstructions coronales ont montré que la veine iliaque interne droite du patient croisait la ligne médiane vers la gauche pour se drainer dans la veine iliaque commune gauche. Cette variation est importante à connaître en chirurgie rétro-péritonéale, laparoscopique et orthopédique. Nous présentons les documents obtenus par tomodensitométrie et discutons l'origine embryologique de cette anomalie congénitale rare.
