To assess the incidence of splanchnic vein thrombosis in patients with Acute Pancreatitis(AP). Objective - To study the involvement of splenic vein(SV), portal vein(PV) and superior mesenteric vein(SMV) in a case of complicated acute pancreatitis. Methodology- An audit of retrospectively collected data for all patients with AP was conducted. Patients with SMV were grouped according to the vessel involvement. Result- Out of 107patients admitted with AP, 25 had Splanchnic vein thrombosis.Out of those 25 cases SV,PV,SMV was observed in 18,15,5 patients respectively. Involvement of more than one vessel was seen in 11 patients(SV and PV in 6 patients,PV and SMV in 3 patients; all the three veins involved in 2 patients). Conclusion- Involvement of SV and PV is more common in splanchnic vein thrombosis than SMV. Involvement of all the three vessels is also a rare condition complicating AP.
