Selective hepatic artery ligation: limitations and failures.

L M Flint, H C Polk

    The Journal of Trauma
    |May 1, 1979
    PubMed
    Summary

    Severe hepatic trauma can cause persistent arterial bleeding. Controlling bleeding involves porta hepatis compression and selective hepatic artery ligation, but requires accurate diagnosis of associated venous injuries.

    Area of Science:

    • Trauma Surgery
    • Hepatobiliary Surgery
    • Vascular Surgery

    Background:

    • Hepatic trauma is a significant cause of mortality.
    • Arterial bleeding from liver wounds presents a critical management challenge.

    Purpose of the Study:

    • To evaluate the efficacy of porta hepatis compression and selective hepatic artery ligation in managing persistent arterial bleeding from severe hepatic trauma.
    • To identify factors contributing to the failure of hepatic artery ligation in these patients.

    Main Methods:

    • Retrospective review of hospital records for 540 consecutive patients with hepatic trauma.
    • Analysis of bleeding control techniques, specifically porta hepatis compression and selective hepatic artery ligation.
    • Assessment of diagnostic accuracy for associated portal and hepatic venous injuries.

    Main Results:

    • Persistent arterial bleeding occurred in approximately 10% of severe liver injuries.
    • Porta hepatis compression effectively controlled bleeding, allowing for subsequent safe and permanent ligation of the lobar artery.
    • Failures of hepatic artery ligation were frequently associated with undiagnosed injuries to the portal and hepatic veins.

    Conclusions:

    • Porta hepatis compression followed by selective hepatic artery ligation is a safe and effective method for controlling persistent arterial bleeding in severe hepatic trauma.
    • Accurate diagnosis of the extent of venous injuries is crucial for the success of hepatic artery ligation.
