[Endolotherapy of massive bleeding from the small intestinal angiodysplasia in 80-year-old patient].

Angiodysplasia is one cause of chronic gastrointestinal tract bleeding that can not be difficult to detect. In particular, angiodysplasia in the small intestine is very rare and has seldom been reported. An 80-year-old man complained of hematochezia and was admitted to other hospital on October 1991. However, no bleeding sites in the gastrointestinal tract could be revealed by radiographic and endoscopic examinations. After 8 months, he was admitted to our hospital with the same symptom on June 1992. He suffered hemorrhagic shock due to continuous bleeding. Hypotension and anemia progressed in spite of immediate blood transfusion. Emergency angiography revealed extravasation from a peripheral branch of the jejunal artery, in addition tortuous and dilated ileal arteries. Embolization was performed with the catheter inserted superselectively into the nearest arcade of the segmental branch of the vasa recta. After embolization, no complications were occurred. He was discharged and is being followed up as an outpatient.
