Treatment and clinical outcome of needle-track seeding from hepatocellular carcinoma

摘要

Background/AimsNeedle-track seeding is a rare but important complication of diagnostic and therapeutic ultrasound (US)-guided procedures in hepatocellular carcinoma (HCC). We examined the frequency of needle-track seeding after US-guided percutaneous ethanol injection (PEI), fine-needle aspiration biopsy (FNAB), and percutaneous transhepatic biliary drainage (PTBD) in order to determine the appropriate treatment for needle-track seeding and its clinical outcome.
