[Extensive venous thrombosis disclosing an aneurysm of the common iliac artery]

Although aneurysms of the common iliac artery are a rare occurrence they should be investigated routinely in patients with urinary or thrombo-embolic venous manifestations in the pelvis minor. Clinical signs are inconstant and diagnosis requires the use of abdominopelvic ultrasound tomography. Venous and urinary complications constitute warning signals suggesting the need for surgery to avoid sudden or untimely rupture. Operation in patients with a poor general condition should be performed as a function of the course of the lesion.
