title: Successful Post-Pancreatitis Pseudoaneurysm Coagulation by Percutaneous Computed Tomography (CT)-Guided Thrombin Injection.
abstract: BACKGROUND
  Pseudoaneurysm is a rare but potentially life-threatening vascular complication of acute pancreatitis, with a mortality rate of 20-43% in untreated patients. The treatment usually involves trans-arterial embolization or surgical resection.
  
  
  METHODS
  A 44-year-old man with a history of acute pancreatitis developed a pseudoaneurysm of the pancreatic tail, diagnosed as a splenic artery pseudoaneurysm by CT. Selective arteriography performed with the purpose of embolization did not reveal the pseudoaneurysm. The day after, under CT guidance, human thrombin (1,000 IU) was injected inside the aneurysmatic sac with its complete occlusion. A control MRI 6 months later confirmed a complete resolution of the pseudoaneurysm.
  
  
  CONCLUSIONS
  Percutaneous coagulation of a post-pancreatitis pseudoaneurysm is a relatively easy and safe procedure, and it can be considered as an alternative to trans-arterial embolization when the pseudoaneurysm cannot be visualized on selective arteriography.
