Angiography in hereditary hemorrhagic telangiectasia.

Hereditary hemorrhagic telangiectasia is a vascular disorder with stigmata in any part of the body. The most frequently reported sites of internal lesions are the lungs, liver and gastrointestinal tract. When one lesion is observed on chest radiography or on splanchnic angiography there is reason to include other vascular areas in the investigation. A normal angiographic finding does not exclude the presence of telangiectasia.
