Splanchnic vein thrombosis (SVT) is a well-known complication of pancreatitis, but extra-splanchnic thrombosis is rarely seen. We report a case of acute necrotizing pancreatitis complicated by portal vein thrombosis and resultant hepatic infarction, splenic vein thrombosis, bilateral renal infarction, and bowel hypoperfusion in an 81-year-old man with recent coronavirus disease 2019 (COVID-19) infection. To the best of our knowledge, this is the first documented case of such extensive intra-abdominal thromboses complicating severe acute pancreatitis. Despite multi-organ support and systemic anticoagulation, he deteriorated into multiple organ failure and died after 72 hours. He had no prior history of thrombotic disorders. COVID-19 infection can cause sustained prothrombotic changes, while severe acute pancreatitis also produces an inflammatory response that promotes coagulation. Together, the two concurrent disease processes may have resulted in the particularly extensive intra-abdominal thromboses and infarctions seen in this patient. Physicians should be mindful of the elevated risk of severe vascular complications in acute pancreatitis patients with concurrent or recent COVID-19 infection.
