[Gastrointestinal angiodysplasia. Clinical, endoscopic, angiographic and histologic study].

: The authors report 10 cases of gastrointestinal bleeding angiodysplasia (4 male and 6 female). The surgical treatment was normally provided and the main clinical features, were observed by radiological, endoscopic and pathological findings. Angiodysplasia was observed in the colon (4 cases), in the small intestine (3 cases) and in the stomach (3 cases). Common symptoms (bleeding and sideropenic anaemia), where possible associated with endoscopic and angiographic study, permitted to determine diagnosis and lesion's extension. Pathological findings showed that vascular dilatation wasn't present only in the mucosa and in the submucosa, as in the amartomatous congenital forms, but was present in all intestinal wall, as in the secondary forms, more frequent.
