Late-developing aortic pseudoaneurysms after surgery, often caused by suture degradation, can be successfully repaired. A specific bypass technique avoids anticoagulation, ensuring safe treatment for these rare aortic complications.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Surgery
  • Aortic Surgery

Background:

  • Aortic pseudoaneurysms are rare but serious complications following aortic surgery.
  • Delayed presentation, sometimes decades after the initial procedure, is characteristic.
  • Suture dehiscence and degradation are implicated as primary causes.

Purpose of the Study:

  • To report the incidence and management of non-infected aortic pseudoaneurysms occurring after aortic surgery.
  • To evaluate the safety and efficacy of a specific surgical technique for thoracic aortic pseudoaneurysm repair.

Main Methods:

  • Retrospective review of 11 cases of non-infected aortic pseudoaneurysms between 1980 and 1991.
  • Surgical correction using a temporary bypass between the right axillary artery and left external iliac artery.

  • Assessment of outcomes, including mortality and need for heparinization.

    • Main Results:

    • 11 cases identified, with a mean interval of 15.2 years from initial surgery.
    • Three pseudoaneurysms presented over 20 years post-operation.
    • All patients underwent successful operative correction without mortality.
    • The described bypass technique eliminated the need for heparinization.

    Conclusions:

    • Non-infected aortic pseudoaneurysms can develop late after aortic surgery, linked to suture issues.
    • Operative correction is feasible and safe, with the employed bypass technique offering a heparin-free approach.
    • This management strategy ensures successful repair of thoracic aortic pseudoaneurysms.
