Improved results for dissecting aneurysms. Intraluminal sutureless prosthesis

G M Lemole, M D Strong, P M Spagna

    The Journal of Thoracic and Cardiovascular Surgery

    Summary

    A novel intraluminal prosthesis technique for thoracic aortic dissection significantly reduces mortality. This method, avoiding end-to-end anastomosis, shows long-term reliability in patients with dissecting aneurysms.

    Area of Science:

    • Cardiovascular Surgery
    • Vascular Surgery
    • Thoracic Surgery

    Background:

    • Surgical treatment for thoracic aortic dissection historically carries high mortality rates.
    • Hemorrhage from prostheses and suture lines is a significant contributing factor to mortality.
    • Existing surgical methods often involve complex procedures with potential complications.

    Purpose of the Study:

    • To evaluate a novel intraluminal prosthesis technique for treating thoracic aortic dissections.
    • To assess the safety, efficacy, and long-term reliability of this minimally invasive approach.
    • To compare outcomes with traditional surgical methods for aortic dissection repair.

    Main Methods:

    • A cohort of 14 patients with thoracic aortic dissections (8 acute, 6 chronic) were treated.

  • The technique utilizes an intraluminal prosthesis, eliminating the need for end-to-end anastomosis.
  • Prostheses were either self-assembled or commercially sourced (USCI); concomitant procedures included aortic valve replacement and coronary artery bypass grafting.

    • Main Results:

    • No intraoperative deaths occurred in the 14 patients.
    • Postoperative mortality included one death from a perforated ulcer and another from empyema.
    • Follow-up (9-51 months) revealed no compromise of the aortic lumen or prosthetic issues (erosion, migration, thrombosis).

    Conclusions:

    • The intraluminal prosthesis technique offers a safe and simple method for repairing dissecting aneurysms of the thoracic aorta.
    • This approach demonstrates long-term reliability and favorable outcomes.
    • The technique is recommended for dissecting, atherosclerotic, and Marfanoid aneurysms of the thoracic aorta.
