OBJECTIVE The obturator veins and their network contribute to major bleeding complications during gynaecologic surgery. METHODS The anatomical variations of the obturator veins were studied on 106 patients in which a thorough bilateral pelvic lymphadenectomy was performed. RESULTS Symmetrical drainage on right and left sides was found in 75 cases: only in internal iliac vein in 32 cases, both in external iliac vein and internal in 41 cases, and only in external in two cases (so called "pubic vein"). In 31 procedures, asymmetric drainage was found between the two sides: one side in internal, the other side both in internal and external in 25 patients; in three patients, in external on one side and in both internal and external on the other; and in external on one side and in internal on the other side in one patient. CONCLUSIONS Anatomical variations of the obturator veins appear quite often.
