About

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

Full description

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.

Enrollment: 10 estimated patients

Sex: All

Ages: 20 to 79 years old

Volunteers: No Healthy Volunteers
