Incidence of Splanchnic Venous Thrombosis in Acute Pancreatitis and it's Correlation With Severity of Pancreatitis

Acute pancreatitis (AP) is a common medical condition characterized by inflammation of the pancreas, affecting a significant portion of the population. With approximately one-third of patients experiencing notable morbidity due to local or systemic complications, the severity of the disease is underscored by the presence of acute peripancreatic fluid collections, acute necrotic collections, pseudocysts, and walled-off necrosis1. Notably, vascular complications, such as splanchnic vein thrombosis, further contribute to the increased morbidity and mortality associated with acute pancreatitis2. Splanchnic vein thrombosis encompasses thromboses in the splenic (SpVT), portal (PVT), and superior mesenteric veins (SMVT), either individually or in combination3. These complications are often incidentally discovered during imaging procedures conducted to assess potential complications4. Despite most cases being asymptomatic, fatal complications, including bowel ischemia, liver failure, portal hypertension, and life-threatening bleeding, have been documented, with the risk of splanchnic vein thrombosis escalating with the severity of pancreatitis
