Isolated Thrombosis of the Superior Mesenteric Vein

Most cases of pancreatitis are mild and self-limited. On the other hand, a few patients with pancreatitis may develop vascular complications. Splenic vein thrombosis is the most common vascular complication of acute pancreatitis. Isolated superior mesenteric vein thrombosis is rare and can lead to gut ischemia and necrosis if not timely diagnosed and managed. We report the case of a 40-year-old patient who presented to the hospital with abdominal pain due to acute pancreatitis, leading to superior mesenteric vein thrombosis, which was timely diagnosed and treated with a good outcome.
