How does the proper hepatic artery travel in relation to the portal vein and CBD?

The proper hepatic artery has a specific anatomical relationship with the main portal vein (MPV) and the common bile duct (CBD) that is crucial for understanding the normal anatomy of the liver and biliary system during ultrasound examinations.

The proper hepatic artery travels anterior to the MPV, which is important because it allows for clear identification of the vascular structures within the hepatobiliary system. This positioning helps differentiate the anatomical structures during ultrasound scans. Furthermore, it also runs to the left of the CBD. This alignment is significant as it aids in visualizing the anatomy during the ultrasound procedure and is essential for accurate diagnosis and interpretation.

This anatomical relationship is important for clinicians to understand because any variation can indicate potential anatomical anomalies or pathological conditions, impacting the approach to interventions or surgeries in the hepatobiliary region.

Understanding this relationship ensures that sonographers can accurately assess the complex vascular and biliary architecture of the liver, which is vital for effective diagnosis and management of liver and biliary disorders.
