abstract：:We recently experienced a case of a female hemodialysis patient with multiple intestinal angiodysplasias. In 2001, she complained of melena, and angiographic embolization halted bleeding from ileum angiodysplasia. In 2002, she again complained of black stool. Abdominal angiography found jejunum angiodysplasia, and pha...
