Surgical treatment is recommended for most anastomotic pseudoaneurysms to prevent rupture and improve patient outcomes. This study reviewed 119 cases, highlighting key findings in vascular surgery.

Area of Science:

  • Vascular Surgery
  • Surgical Complications
  • Aneurysm Management

Background:

  • Anastomotic pseudoaneurysms remain a significant challenge in reconstructive vascular surgery, even with optimal surgical techniques.
  • These pseudoaneurysms pose risks of rupture and thromboembolism, necessitating effective management strategies.
  • Identifying causative factors is crucial for preventing and treating these complications.

Purpose of the Study:

  • To evaluate the outcomes of surgical intervention for anastomotic pseudoaneurysms.
  • To determine the efficacy of surgical repair in preventing pseudoaneurysm rupture and improving patient prognosis.
  • To analyze the incidence, presentation, and causative factors of anastomotic pseudoaneurysms.

Main Methods:

  • Retrospective review of 119 anastomotic pseudoaneurysms treated surgically in 68 patients between 1981 and 1986.

  • Surgical repair typically involved resection of the anastomosis and involved host artery.
  • Extra-anatomic bypass was utilized for limb salvage in cases of septic aneurysms.

    • Main Results:

    • 31.0% of pseudoaneurysms were infected, and 13.1% were recurrent.
    • The femoral region, particularly after aortobifemoral bypass, was the most common site.
    • Postoperative mortality was 8.8%, with a 10.9% rate of minor complications and 13.1% amputation rate.

    Conclusions:

    • Surgical treatment is generally recommended for anastomotic pseudoaneurysms, except in high-risk patients, to mitigate rupture and thromboembolism.
    • Host vessel degeneration and anastomotic inflammation are key etiological factors.
    • While effective, surgical repair carries significant risks, including mortality, complications, and limb loss, underscoring the need for careful patient selection and surgical planning.
