ABSTRACT

Objective To evaluate the effects of diagnosis and treatment of acute pancreatitis com- plicating pseudoaneurysm by CT scan and transcatheter embolization.Methods Eighteen cases of acute panereatitis complicating pseudoaneurysm were performed abdominal angiography and transcatheter em- bolization.The CT and digital substraction angiography(DSA)findings and clinical data were retrospec- tively analyzed.The location of pseudoaneurysm and hemostasis were observed.Results CT scan re- vealed regional or diffuse slight high density fluid collections in abdominal cavity of all patients.En- hanced CT showed contained extravasation of contrast which indictated ruptured the pseudoaneurysm. DSA revealed 22 pseudoaneurysm,and 20 had evidence of bleeding.All pseudoaneurysms were success- fully embolized with coils,and hemostasis was achieyed in 18 pseudoaneurysm immediately.Conclusions The acute pancreatitis complicating pseudoaneurysm can be examined with CT scan and transcatheter embolization is safe and effective therapeutic method.
