Does Ptcd Puncture Needle Have Anesthesia?

Percutaneous hepatocentesis biliary drainage (PTCD) is a technique in which a catheter is placed percutaneous through the liver in the biliary tract under imaging techniques (X-ray or B-ultrasound guidance). For many biliary diseases, PTCD is the first choice of treatment and can also be a palliative treatment.
