The ascending aortic aneurysm: replacement or repair?

L Egloff, M Rothlin, J Kugelmeier

    The Annals of Thoracic Surgery

    Summary

    This study compared four surgical methods for ascending aortic aneurysms. Reduction aortoplasty with a synthetic net showed lower complication rates for specific patient groups, offering a viable alternative.

    Area of Science:

    • Cardiovascular Surgery
    • Thoracic Surgery
    • Aortic Aneurysm Treatment

    Background:

    • Ascending aortic aneurysms encompass various pathologies including dissection, dilatation, and inflammatory disease.
    • Surgical intervention is crucial for managing ascending aortic aneurysms.

    Purpose of the Study:

    • To retrospectively compare the outcomes of four distinct surgical procedures for ascending aortic aneurysms.
    • To identify the most suitable operative method based on aneurysm type and patient characteristics.

    Main Methods:

    • Analysis of 100 patients operated on between 1971 and 1980 for ascending aortic aneurysms.
    • Four surgical techniques were evaluated: repair and reduction aortoplasty, nylon-reinforced reduction aortoplasty, supracoronary graft replacement, and composite graft replacement.

  • Retrospective comparative analysis of early and late mortality and complication rates.

    • Main Results:

    • Overall early mortality was 10% and late mortality was 12% after a mean follow-up of 45 months.
    • Nylon-reinforced reduction aortoplasty demonstrated a lower complication rate (cerebrovascular accidents, myocardial infarction) compared to graft replacements in selected patients.
    • Supracoronary graft replacement is preferred for acute/chronic dissection with an intact aortic root.
    • Composite graft replacement is the procedure of choice for annuloaortic ectasia, dilated sinus of Valsalva, and Marfan's syndrome.

    Conclusions:

    • Nylon-reinforced reduction aortoplasty is a suitable method for ascending aortic aneurysms without dissection or inflammatory disease, provided careful attention is paid to anchor stitches.
    • Graft replacement techniques offer distinct advantages for specific aortic pathologies, guiding surgical decision-making.
