Biliary Interventions

The biliary system involves the production and transportation of bile with the help of the liver, bile ducts, and gallbladder. Obstructions may develop in the bile ducts as a result of infection, scarring, stones or cancers of the liver or pancreas, and may prevent bile from flowing from the liver to intestines to aid in the digestive process. There are several minimally invasive procedures available to relieve these blockages and restore the flow of bile while eliminating the need for surgery.

Biliary Drainage Catheter Placement

If excess fluid builds up in the bile ducts of the liver, a catheter tube may be placed to drain the fluid into the intestines or into a bag outside of the body. This will help relieve a blockage in the bile ducts and facilitate normal drainage of bile from the liver to the intestines.

During the catheter placement procedure, a needle will be placed into the bile duct under X-ray guidance. The drainage catheter will then be fed to the duct as well, and will be attached to the intestines or an external bag.

Biliary Stent Placement

During the stent placement procedure, a small metal tube is placed within the duct at the site of the obstruction to open up the blockage and allow bile to flow through the duct and into the intestines.

Hemodialysis Access Management

Hemodialysis is a common treatment method for chronic renal disease that filters the blood and removes waste and extra fluids, allowing only clean blood to flow through the body. Removing the excess waste can help control blood pressure and monitor the balance of chemicals such as potassium and sodium. Hemodialysis shunts may be susceptible to low blood flows as a result of clotting or narrowing of the blood vessels associated with the shunt. In order to correct this problem and restore proper blood flow, angioplasty or thrombolysis may be needed.
