Low digestive hemorrhage caused by a vascular malformation in a patient with Crohn's disease: case report and literature review

Hemorragia digestiva baixa por malformação vascular em paciente com doença de Crohn: relato de caso e revisão da literatura

ABSTRACT

The authors report the case of a 19-year-old male patient with Crohn's disease treated with infliximab and azathioprine, with sustained clinical remission; in the course of the evolution, this patient showed a vascular malformation in his rectum, with daily massive bleeding, in need of several blood transfusions and finally with an indication for surgical treatment. Data from the literature on the association of the injury at issue and CD, as well as the drugs used by the patient, are evaluated. The literature lacks information linking this malformation with CD or with the drugs used.
