Mesenteric thrombosis: An unusual complication of severe acute pancreatitis—Report of two cases

Abstract The incidence of acute pancreatitis is 34 per 100 000 people in the general population and is on the rise. Approximately 15% to 20% of all patients experience severe pancreatitis, with a mortality rate nearing 20%. This condition is often linked to vascular complications, although mesenteric thrombosis is a rare presentation. We present two cases of severe acute pancreatitis resulting in multiple organ failure. Histopathological examination revealed acute hemorrhagic pancreatitis with necrosis and mesenteric thrombosis in both cases. Mesenteric thrombosis, though uncommon, is a serious complication with atypical symptoms and high mortality rates. Vascular complications in severe acute pancreatitis should not be overlooked. This case report underscores the significance of recognizing such rare complications and the need for comprehensive consideration in clinical assessments.
