Hepatic Arterial Infusion

What Hepatic Arterial Infusion Means

Hepatic arterial infusion (HAI) is a medical procedure used to deliver chemotherapy drugs directly into the liver. This is done by placing a small catheter into the hepatic artery, the blood vessel that carries oxygen-rich blood to the liver. A pump is usually implanted under the skin to continuously or periodically deliver chemotherapy through this catheter. The goal is to target liver tumors more precisely by using the liver’s blood supply system.

Why Hepatic Arterial Infusion Can Matter in Cancer Care

Many cancers, such as colorectal cancer, can spread to the liver. These liver tumors often receive most of their blood supply from the hepatic artery, unlike normal liver tissue, which mainly gets blood from the portal vein. By delivering chemotherapy directly into the hepatic artery, HAI aims to expose cancer cells to higher drug concentrations while limiting the amount of chemotherapy circulating throughout the rest of the body. This targeted approach may improve treatment response for patients with liver metastases that cannot be removed by surgery.

What Patients Might See or Experience

If your care team discusses hepatic arterial infusion, you might hear about a surgical procedure to place a pump and catheter. Before surgery, imaging tests are done to map the liver’s blood vessels and check for any unusual anatomy. During surgery, the gallbladder is often removed to reduce the risk of side effects. After placement, tests with special dyes or scans confirm that the chemotherapy will flow only to the liver and not to other organs like the stomach or intestines.

Patients may experience side effects related to the surgery, such as pain or infection at the pump site, or complications involving the catheter. Chemotherapy delivered by HAI can cause side effects including stomach upset, liver inflammation, or effects on the bone marrow. Your care team will monitor closely to manage these risks.

Where You Might Encounter This Term

You may see hepatic arterial infusion mentioned in your medical records, treatment plans, or discussions about options for liver metastases. It might also appear in clinical trial descriptions or drug information if HAI is part of an experimental or combined treatment approach. Because it is a specialized procedure, it is usually offered at centers with experience in placing and managing these pumps.

What Hepatic Arterial Infusion Does Not Automatically Mean

Seeing the term hepatic arterial infusion does not mean you have liver cancer or that this treatment is right for you. It simply describes a way chemotherapy can be delivered to the liver. Whether HAI is appropriate depends on many factors, including the type and extent of cancer, overall health, and other treatments being used.

Questions to Ask Your Care Team

If you hear about hepatic arterial infusion, consider asking: How does this procedure fit into my treatment plan? What are the benefits and risks for me? What should I expect before, during, and after the pump placement? How will side effects be managed? Are there alternatives to this treatment? Understanding these details can help you feel more informed and involved in your care decisions.

How to Read the Term in Context

Because hepatic arterial infusion is a technical term, it’s important to look at the full context when it appears in your medical information. Ask your healthcare providers to explain what it means for your specific situation rather than assuming it refers to a diagnosis or a guaranteed treatment option. This helps avoid confusion and ensures you get clear, personalized information.

Safety and Next Steps

This explanation is for educational purposes and does not replace medical advice. The decision to use hepatic arterial infusion depends on individual health factors and should be made with your care team. If you see this term in your records or hear it during visits, the best next step is to ask your healthcare providers what it means for your care and how it applies to your diagnosis and treatment options.
