View Full Version : Kỹ thuật PTBD (Percutaneous Transhepatic Biliary Drainage)

18-11-10, 06:50 PM
Percutaneous transheptic biliary drainage (PTBD) is a procedure to drain the bile ducts in the presence of a blockage or damage that prevents normal bile drainage.
Using fluoroscopy (live x-ray), a needle is guided into the bile ducts, where a contrast agent is injected to allow visualization on a monitor. A catheter is placed into the bile duct to allow the bile to drain out into a bag outside the body. To prevent further drainage difficulties, a stent may be placed in a blocked or restricted bile duct to hold it open and allow bile to flow freely.
