• Idiopathic rupture of large veins is very rare. There has been one report in the Portugese literature of such an instance involving the iliac vein. Our patient was an elderly woman in whom evidence of intra-abdominal hemorrhage developed. There was no clinical evidence of trauma. At laparotomy a large retroperitoneal hematoma secondary to an 8-mm tear in the left common iliac vein was found. The tear occurred adjacent to where the right common iliac artery passes over the vein. Repair was followed by uneventful recovery. Results of the pathological examination showed nonspecific information.
