This study aims to evaluate the usefulness of hemostasis using radiofrequency ablation for track bleeding that has occurred after percutaneous biopsy of the liver.

Purpose: To evaluate the usefulness of hemostasis using radiofrequency ablation for track bleeding after percutaneous liver biopsy.

Method:

• Enroll patients who continue to bleed despite conservative treatment for track bleeding that has occurred after liver biopsy.
• Radiofreqeuncy ablation: Under monitoring vital signs and controlling pain with intravenous agents, the electrode is inserted into the bleeding focus. The bleeding focus is ablated.
• Hemostasis is evaluated by ultrasound (right after radiofrequency ablation), CT scan (after the radiofrequency ablation), and ultrasound (the day after radiofrequency ablation)
• If hemostasis fails using radiofrequency ablation, transarterial hepatic embolization is performed immediately.

Inclusion Criteria:

• Ultrasound guided percutaneous liver biopsy at Samsung Medical Center
• Track bleeding after biopsy
• Persistent track bleeding even after conservative management
• Consent to this study

Exclusion Criteria:

• Not consent to this study
• <20 years old or >=80 years old
• Contraindication to radiofrequency ablation
• Radiofrequency ablation for track bleeding is not technically possible.
• Unstable vital signs
