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