[Recurrent massive hemorrhage of the distal part of the digestive tract due to hemorrhagic hereditary telangiectasia].

Massive gastrointestinal bleeding is known to occur in patients presenting the hemorrhagic hereditary telangiectasis condition known as Rendu-Osler-Weber (ROW) disease. Bleeding is most frequent in the fourth decade. Endoscopic coagulation of upper gastrointestinal telangiectatic spots is nowadays possible even in the presence of active bleeding. In the lower digestive tract the naevi are basicallly located on the terminal ileum and the right colon; emergency coloscopic examination is difficult when active bleeding occurs. 10-15% of ROW patients present sudden life-threatening episodes of bleeding. The danger is aggravated through delayed diagnosis as well as difficulty in localizing the hemorrhagic area. Selective angiogram of the three digestive arteries is a safe and efficient method of diagnosing the nature and source of the bleeding. It should be obtained routinely, on an emergency basis, before surgery. Operation includes removal of the involved part of the digestive tract. A specimen angiogram should be obtained during the procedure, to make sure that the bleeding malformation has been removed. Laparotomy without preliminary angiogram is likely to be unsuccessful. An illustrative case is presented.
