Should anticoagulants be administered for portal vein thrombosis associated with acute pancreatitis?

Figure 1 Abdominal computed tomography images. A: A filling defect and intra-luminal hypoattenuation in the portal vein consistent with acute portal vein thrombosis; B: A 12 mm × 10 mm cystic lesion suggestive of a pseudocyst and extensive inflammatory fluid collections around the pancreatic head; C: A walled-in fluid collection with high attenuation, indicative findings of a hemorrhagic pseudocyst around the pancreatic head and compressed duodenum; D: Reduced hemorrhagic fluid collections and an air-filled cyst, indicative of a fistula between the duodenum and the pseudocyst.
