[Angiodysplasia of the colon combined with portal hypertension and recurrent gastrointestinal bleeding].

Angiodysplasia of the colon has been reported as one of the most common sources of lower gastrointestinal bleeding in the elderly whereas it is very rare in younger patients. Apart from this, portal hypertension may also have effects on the colon. There are, however, only a few reports which have investigated the colon in patients with portal hypertension. We report the case of a 16-year-old woman who presented massive bleeding from angiodysplasia of the colon assembled together with portal hypertension due to portal vein thrombosis caused presumably by neonatal umbilical cord infection. In this regard we discuss diagnosis, therapy and prognosis of this disease.
