Persistent left hepatic venous connection with the coronary sinus

P C Bunger, W W Parke

    The Anatomical Record
    |May 1, 1982
    PubMed
    Summary

    A rare anomalous connection between the left hepatic vein and the coronary sinus was found in two cadavers. This venous anomaly, though usually insignificant, may be linked to cardiac arrhythmias, highlighting the need for identification.

    Area of Science:

    • Anatomy
    • Cardiovascular System
    • Venous Anomalies

    Background:

    • The central systemic venous system's development is complex.
    • Variations in venous connections can occur during embryogenesis.
    • The hepatic veins and coronary sinus are critical components of the systemic and cardiac venous return, respectively.

    Purpose of the Study:

    • To describe a rare anomalous direct connection between the left hepatic vein and the coronary sinus.
    • To review the normal development of the central systemic venous system in the hepatic region.
    • To propose a potential explanation for the observed anomalous configuration.

    Main Methods:

    • Cadaveric dissection was performed.
    • Anatomical variations of the central venous system were examined.
    • Developmental embryology of the venous system was reviewed.

    Main Results:

    • A direct anomalous connection between the left hepatic vein and the coronary sinus was identified in two specimens.
    • No abnormal shunting of blood was associated with this anomaly.
    • The anomaly was considered clinically insignificant in the absence of other factors.

    Conclusions:

    • This case report details a rare venous anomaly involving the left hepatic vein and coronary sinus.
    • While hemodynamically insignificant, such anomalies may be associated with cardiac arrhythmias.
    • Identification of this venous variation is important due to potential clinical implications, particularly cardiac arrhythmias.
