Abstract

BACKGROUND/AIMS:

Pseudoaneurysm is a life-threatening complication of chronic or acute pancreatitis. This study was undertaken to evaluate the clinical features of pseudoaneurysm complicating pancreatitis.

METHODS:

We reviewed the medical records of 7 patients diagnosed as pseudoaneurysms with chronic pancreatitis in Korea University Guro and Anam Hospital from January 1995 to March 2006 and analyzed their demographics, clinical courses and outcomes.

RESULTS:

All patients were men and mean age was 54.6 years (range, 43-67 years). All the cases occurred in the setting of chronic alcoholic pancreatitis complicated by pseudocyst. Abdominal pain was the unique initial clinical symptom in 5 cases, hematemesis in 1 case, and simultaneous abdominal pain with hematemesis in 1 case. Bleeding into pseudocyst developed in 5 cases, flowing into duodenum through pancreatic duct in 1 case and rupture into the descending colon in 1 case. Mean duration between onset of symptom and diagnosis of pseudoaneurysm was 7.8 days (range, 1-23 days). Six cases were diagnosed by abdominal computed tomography disclosing characteristic finding of focal high density area in the pseudocyst. Pulsed doppler abdominal sonography was performed before computed tomography in 3 cases and results were negative in 2 cases. Transcatheter arterial embolizations were initially performed in 6 cases, and there was no recurrent bleeding except one case of splenic infarction. Distal pancreatectomy was initially performed in 1 case.

CONCLUSIONS:

Pseudoaneurysms complicating chronic pancreatitis shows various clinical features. Transcatheter arterial embolization can be recommended as a primary therapeutic modality.
