Persistent left hepatic venous connection with the coronary sinus

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.
