Massive haematemesis as the first manifestation of superior mesenteric and portal vein thrombosis in a healthy young adult.

ABSTRACT: Superior mesenteric vein (SMV) and portal vein thrombosis are rare but serious causes of intestinal ischaemia, and haematemesis as an initial presentation is highly uncommon. We report the case of a 39-year-old previously healthy man who presented with acute haematemesis following diffuse abdominal pain.

Emergency laparotomy confirmed extensive jejunal and ileal gangrene, requiring near-total small-bowel resection with end jejunostomy.
