What Is Percutaneous Hepatic Puncture Needle Biliary Drainage?

percuteneous transhepatic cholangio drainage, PTCD. There are also cases in which cholangio is written as bileduct or biliary. PTBD (also known as PTBD) refers to a series of techniques in which bile flows to the outside of the body or duodenum through percutaneous bile duct puncture and drainage tube insertion under the guidance of imaging equipment (usually X-ray or B-ultrasound). It is mainly used in the treatment of biliary obstruction and acute inflammation.

Percutaneous hepatocentesis biliary drainage (PTCD) is an interventional therapy technique developed on the basis of percutaneous hepatobiliary angiography (PTC). PTC is a progressive direct biliary angiography method that uses a special puncture needle to penetrate the intrahepatic bile duct under the surveillance of DSA or B-ultrasound, and then directly inject the contrast agent into the bile duct to rapidly develop the intrahepatic and intrahepatic bile ducts. Clinically, obstructive jaundice caused by benign and malignant lesions can be treated by PTCD, which can quickly relieve the tension of the intrahepatic bile duct and improve the symptoms, thus creating conditions for elective surgery, and can also be used as a means of long-term palliative care to improve the quality of life of patients and prolong the survival time. In recent years, with the gradual improvement and development of puncture instruments and puncture techniques, PTCD has included a variety of interventional therapy techniques such as external biliary drainage, internal-external drainage and internal drainage. Different drainage methods were selected according to the type and degree of patients' lesions.
