Transcatheter arterial embolization in treatment of severe acute pancreatitis complicated with hemorrhagic pseudoaneurysm / 中国介入影像与治疗学

ABSTRACT

Objective: To investigate the value of transcatheter arterial embolizaiton (TAE) in treatment of severe acute pancreatitis (SAP) complicated with hemorrhagic pseudoaneurysm. Methods: TAE was performed in 13 patients with SAP complicated with ruptured pseudoaneurysm. DSA findings and embolization of pseudoaneurysm were analyzed. Results: There were 15 pseudoaneurysms in 13 patients, including 13 infective pseudoaneurysms and 2 corrosive pseudoaneurysms. The responsible arteries included splenic artery in 6 lesions (6/15, 40.00%), superior mesenteric artery in 5 lesions (5/15, 33.33%), gastroduodenal artery in 2 lesions (2/15, 13.33%), inferior mesenteric artery in 1 lesion (1/15, 6.67%) and right gastroomental artery in 1 case (1/15, 6.67%). The technical success rate of TAE was 93.33% (14/15). One case developed splenic abscess after TAE and was treated with puncture drainage and anti-infection measures. The mortality rate of patients with infective pseudoaneurysms was 45.45% (5/11). No death occurred in corrosive pseudoaneurysm patients. Recurrent bleeding rate after TAE was 15.38% (2/13). Conclusion: TAE is an effective method for treatment of SAP complicated with ruptured pseudoaneurysm.
