[Angiodysplasia of the colon: a presentation of 7 cases]. / Angiodisplasias del colon: presentación de siete casos.

Angiodysplasias of the colon are small vascular lesions that probably affect 25% of the population over 50 years. As a result of selective arteriography the number of diagnoses of lower gastrointestinal hemorrhage (HDB) caused by a colonic angiodysplasia (CA) has increased considerably. Seven new cases of colonic angiodysplasia (6 cecal and 1 rectal) are presented, all diagnosed by arteriography. In 6, treatment was surgical and in one, medical. The postoperative bleeding recurrence was 33.3%.
