External iliac venous aneurysm treated with tangential aneurysmatectomy and lateral venorrhaphy: a case report and review of the literature.

Venous aneurysms of the femoro-iliac axis are uncommon abnormalities of the vascular system with a potentially life-threatening course; they can be associated with the disastrous events of thromboembolism or rupture. Therefore, a focused imaging evaluation and prophylactic treatment is essential. The appropriate surgical approach is, however, dictated by the morphological parameters and the extent of the aneurysm.
