Abstract
Hepatic artery aneurysms are relatively infrequent lesions and may represent significant problems in both diagnosis and management. Indeed, as many as 30 to 50 per cent of cases are completely unsuspected and are discovered only at autopsy. A case of a very large hepatic artery aneurysm (greatest dimension of approximately 35 centimeters) presenting as an asymptomatic epigastric mass is reviewed, with emphasis on preoperative evaluation and operative technique. Selective arteriography was the cornerstone of diagnosis with other investigative modes proving not to be effective. Surgical therapy included obtaining proximal and distal control, meticulous ligation of the numerous feeding vessels, and finally evacuation and partial excision of the aneurysm sac with careful suture ligation obliteration of the orifice of each feeding vessel. Restoration of hepatic artery flow was not attempted and no compromise in liver function was seen in the postoperative period. The literature on hepatic artery aneurysms is reviewed to include typical presentation, diagnostic methods, surgical approach, and common complications. Only through a high index of suspicion and early angiography can this frequently fatal lesion be detected early in its course and subsequently be subjected to successful surgical management.
