Which vessels should be evaluated for patency before and after liver transplants?

The vessels that should be evaluated for patency before and after liver transplants include the portal vein, hepatic veins, inferior vena cava (IVC), and hepatic artery.

Assessing these specific vessels is crucial during transplant evaluation for several reasons. The portal vein is responsible for transporting blood from the gastrointestinal tract and spleen to the liver, and ensuring its patency is vital for the proper blood flow necessary for liver function. The hepatic veins are responsible for draining blood from the liver back to the heart, and any obstruction in these veins can lead to significant complications post-transplant. Evaluating the IVC is essential because it serves as a major conduit for blood returning to the heart from the abdomen and lower body, and any issues can affect overall hemodynamics. Finally, the hepatic artery supplies oxygenated blood to the liver and is critical for its metabolic activities, making its assessment for patency essential both pre- and post-transplant.

Considering these factors, monitoring the patency of these vessels can help prevent complications and ensure the success of the transplantation procedure.
