Clinical Features and Treatment Outcomes of Pseudoaneurysm Following Pancreatic Resection

Anticancer Res. 2022 Mar;42(3):1579-1588. doi: 10.21873/anticanres.15632.

Abstract

Background/aim: Management strategies for pseudoaneurysm rupture after pancreatic resection have not yet been firmly established due to its low incidence and effects of environmental variability among centers. This study aimed to provide a basis for treatment strategy improvement.

Patients and methods: Clinical features and outcomes of 29 patients who experienced pseudoaneurysm formation or rupture following pancreatic resection were retrospectively reviewed.

Results: The incidence of pseudoaneurysm formation was 2.8%. In 28 of 29 patients, pseudoaneurysm was identified via emergent dynamic computed tomography (CT). The rates of complete cessation of bleeding by interventional radiology (IVR) and surgical intervention were 88% and 100%, respectively. Mortality rate was 13.8%. Four patients treated by IVR died, including three of massive bleeding and one of liver failure.

Conclusion: Patients with suspected pseudoaneurysm rupture after pancreatic resection should undergo immediate CT. Open surgery is preferable for patients with incomplete hemostasis by IVR or those who cannot immediately undergo IVR, however, IVR is an effective alternative.
