Postoperative median sternotomy dehiscence.

A Harjula, A Järvinen

    Scandinavian Journal of Thoracic and Cardiovascular Surgery
    |January 1, 1983
    PubMed
    Summary

    Sternal dehiscence after median sternotomy is a rare but serious complication, affecting 0.56% of patients. Key risk factors include excessive blood loss, infections, and respiratory issues, highlighting the need for careful surgical closure techniques.

    Area of Science:

    • Cardiovascular Surgery
    • Thoracic Surgery
    • Surgical Complications

    Background:

    • Median sternotomy is a common surgical approach for open-heart procedures.
    • Sternal dehiscence is a significant complication that can lead to increased morbidity and mortality.

    Purpose of the Study:

    • To analyze the incidence and risk factors of sternal insufficiency after median sternotomy.
    • To identify preventative measures for sternal dehiscence.

    Main Methods:

    • Retrospective analysis of 2130 patients undergoing median sternotomy.
    • Review of patient records to identify cases of sternal dehiscence and associated factors.
    • Surgical re-exploration in affected patients to determine the cause of sternal instability.

    Main Results:

    • Sternal insufficiency occurred in 12 patients (0.56%), with 11 cases during the initial hospital stay.
    • Causes included wire interruption, loosening, or cutting through sternal bone.
    • Common risk factors identified: excessive blood loss, transfusion requirements, postoperative wound infections, respiratory complications, and obesity.

    Conclusions:

    • Sternal dehiscence is infrequent but serious, particularly after open-heart surgery.
    • Preventative strategies include meticulous sternal closure and avoiding excessive bone wax.
    • Managing risk factors like infection and optimizing respiratory support are crucial.
