Intestinal arteriovenous malformations: a diagnostic and therapeutic challenge

Arteriovenous malformations (AVM) of the intestine are rare causes of gastrointestinal bleeding. Diagnosis depends upon accurate interpretation of imaging features and histopathology to differentiate them from other vascular malformations. Presentation of colonic AVM with mucous diarrhea and pain is rare and poses diagnostic challenges. Usually, patients presenting with bleed need surgical intervention. The current report discussed one patient with chronic liver disease, extrahepatic portal vein thrombosis with small bowel AVM and two patients with colonic AVM, highlighting management strategies adopted.
