    Abstract:
    OBJECTIVE: To report the experience in diagnosis and management of bleeding pseudoaneurysms associated with severe acute pancreatitis (SAP). METHODS: The medical records of 12 patients with bleeding pseudoaneurysms associated with SAP treated between October 1990 and October 2006 were retrospectively reviewed. The etiologies of the 12 patients were gallstones in 6 patients, hyperlipidemia in 3 patients, hyperparathyroidism in 1 patient and the other 2 patients had no definitive causes. RESULTS: Abdominal computed tomography revealed bleeding pseudoaneurysms in 6 of 9 patients. Angiography determined correct diagnosis in 12 patients (12/12). The most involved vessels were peripancreatic arteries. Eight patients were managed by trans-catheter arterial embolization (TAE) as "one point" (a proximal point of the pseudo-aneurysm). Two patients were treated by TAE as "two points" (both distal and proximal to the pseudo-aneurysm). The last two cases were treated by surgery as suture and ligation. Four of the "one point" TAE patients were re-bleeding 4 to 7 days later, and 2 of them were treated with surgery, the other 2 patients were controlled with "two points" TAE. Three patients were died of infection and multiple organ dysfunction syndromes. Overall mortality rate was 25% (3/12). CONCLUSIONS: Angiography is the main diagnostic methods for bleeding pseudoaneurysms in SAP patients. "Two points" embolization and emergency surgery are an effective treatment options in these patients.
