Diagnosis and treatment of pseudoaneurysm complicated with pancreatitis / 中华消化内镜杂志

ABSTRACT

Objective To analyze the diagnosis treatment and methods for pancreatic pseudoaneurysms complicated with pancreatitis. Methods The diagnostic methods,treatments and clinical effects of 11 patients with pancreatic pseudoaneurysms complicated with pancreatitis from January 2006 to December 2014 were retrospectively analyzed in Shengjing hospital. Results Two cases of pancreatic pseudoaneurysms were diagnosed by endoscopic ultrasonography(EUS). Eight cases were diagnosed with contrast-enhanced computed tomography. One case was diagnosed by angiography. Ten patients received endovascular embolization,and nine of them were successfully treated. Rebleeding occurred in one patient 28 days after embolization,and was successfully treated by repeated embolization. One patient was successfully treated by surgery. Conclusion Contrast-enhanced computed tomography and angiography are the current main methods to diagnose pancreatic pseudoaneurysms. With the wide use of EUS in the diagnosis of pancreatic disease,EUS becomes an option for diagnosis of pancreatic pseudoaneurysm. Traditionally, pancreatic pseudoaneurysm is treated by surgery. With the advancement of endovascular techniques, endovascular treatment has become the first-line treatment. Further studies with a large sample size are needed to establish the better diagnostic methods and treatments for pancreatic pseudoaneurysm.
