Non-traumatic rupture of the iliac vein.

Two cases of non-traumatic rupture of the iliac veins have invited a review of eight previous cases reported in the literature. The condition is worthwhile reviewing as the clinical signs and findings very much resemble the picture of a ruptured aneurysm including sudden or fairly rapid onset of hypovolaemia and a tender, lower abdominal mass. In addition, concomitant iliac vein thrombosis is a common finding which is likely to contribute to rupture. The management is resuscitation and repair of the vein.
