Pseudoaneurysm has become a high-risk surgical complication in hepatobiliary-pancreatic malignancies. We studied thecause, surgery, treatment, and outcome in cases seen over, the last 5 years at our insitute using abdominal angiography and transarterial embolization (TAE) in diagnosis and treatment. Pseudoaneurysm after choledochojejunostomy with hepatectomy involved prolonged duration after onset take a lot of time and, with bacterial infection, high movtality. Additional surgery was required in some cases, TAE had a poor effect. Extended surgery involving hepatobiliary-pancreatic malignancy meny improve survival but high-risk postoperative complications must be kept in mind. Whenever postoperative pseudoaneurysm is suspected, ultrasonography, computerized tomography, and angiography should be conducted immediately.
