A SUCCESSFUL FACIAL ARTERY EMBOLIZATION BY USING COLLAGEN, POLYVINYL ALCOHOL (PVA) AND ISOBUTYL-2-CYANOACRYLATE (IBCA) FOR RIGHT MANDIBULLAR TUMOR

Abstract

We developed a new interventional technique of intraarterial embolization using microfibrillar collagen (MC), polyvinyl alcohol (PVA) and isobutyl-2-cyanoacrylate (IBCA) for patients with malignant tumor of the right mandible. The purpose of this report is to demonstrate the methodology of an interventional technique using MC, PVA and IBCA. Case: a 50-year-old man, suddenly suffered bleeding from his right facial artery. Both the facial and lingual arteries were occluded by MC. Recanalization and re-bleeding occurred on postoperative day 14, although distal vessels of the facial or lingual artery were shown in an agiogram to be occluded. He received a 2 nd interventional procedure by using MC, PVA, and IBCALipiodol mixture (IBCA: Lipiodol=1: 0.7) . This stopped the bleeding. At this embolization, we selected the MC clinically to obstruct the distal vessel ; later, we selected PVA to embolize the tumor itself; finally, we selected IBCA-Lipiodol mixture to obstruct the feeder to the tumor. It was concluded that the interventional technique of intraarterial embolization by using MC, PVA and IBCA-Lipiodol mixture is very reliable and safe at the time of tumor bleeding.
