Surgical repair of hepatic artery aneurysms (HAA) is effective, but graft patency is poor if the gastroduodenal artery is excluded. Comprehensive vascular evaluation and follow-up are crucial due to associated aneurysms.

Area of Science:

  • Vascular Surgery
  • Abdominal Aneurysms
  • Hepatic Artery Diseases

Background:

  • Hepatic artery aneurysms (HAA) are rare vascular conditions.
  • Atherosclerosis is the primary etiology in most cases.
  • HAAs can be symptomatic or asymptomatic, with rupture posing a significant risk.

Purpose of the Study:

  • To review surgical outcomes for hepatic artery aneurysms.
  • To identify factors influencing graft patency and patient mortality.
  • To emphasize the importance of thorough vascular assessment.

Main Methods:

  • Retrospective review of 12 patients undergoing surgical treatment for HAA between 1979 and 1991.
  • Diagnostic modalities included ultrasonography, computed tomography, and arteriography.

  • Surgical approaches involved hepatic artery ligation or reconstruction, with analysis of graft patency and associated procedures.

    • Main Results:

    • Atherosclerosis was the cause in 10 of 12 patients, with the common hepatic artery most frequently involved.
    • Rupture occurred in two cases, one into the portal vein and one iatrogenic.
    • Graft patency was significantly lower (25%) when the gastroduodenal artery was excluded from repair.
    • Mortality was 100% for emergent surgery versus 9.1% for elective procedures.

    Conclusions:

    • Surgical repair of HAAs can be successful, but careful surgical technique is essential.
    • Exclusion of the gastroduodenal artery from repair is associated with poor graft patency.
    • Patients with HAAs often have other aneurysms, necessitating complete vascular evaluation and long-term follow-up.
