Pseudoaneurysm of the hepatic artery. A rare complication after orthotopicliver transplantation

Introduction: Pseudoaneurysm of the hepatic artery is a rare complication o f liver transplantation, the most common cause of which - apart from techni cal surgical problems - is an infection. The most common symptoms are ruptu re and hemorrhage. Method: The present case report describes an asymptomati c pseudoaneurysm of the hepatic artery following liver transplantation, and its treatment. Results: In this patient, an pseudoaneurysm involving an er oded branch of the hepatic artery was found. Surgical treatment consisted i n the excision of the aneurysm and oversewing of the branch of the hepatic artery. Conclusion: The potential for rupture and hemorrhage makes surgical intervention mandatory even in asympotomatic patients with pseudoaneurysm of the hepatic artery. The surgical procedure depends on the local situatio n and the time elapsed since transplantation. Preservation or reconstructio n of the arterial perfusion is essential.
