Angiography > Exams & Procedures > Liver (Biliary) Drain
A liver (biliary) drain is necessary when the biliary tree is obstructed. Usually the patient is jaundiced (yellow). Ultrasound guidance is used to visualize the biliary system. Local anaesthetic is given to numb the area. A fine needle is inserted to verify placement with the injection of contrast. A small catheter is placed into the liver to drain bile. The procedure can take one to two hours. Most patients are admitted overnight to the hospital for this procedure.
A light breakfast the day of the procedure is allowed. Take your usual medication. If you are on blood thinners, let us know so the appropriate blood work can be done.
