Intraosseous Embolotherapy of Central Arteriovenous Malformations in the Jaw: Long-Term Experience With 8 Cases

Purpose: To investigate the long-term effects of direct intraosseous histoacryl embolotherapy on central arteriovenous malformations (AVMs) of the jaw Materials and Methods: Eight patients with central AVMs of the jaw (3 in the maxilla and 5 in the mandible) were treated with direct intraosseous histoacryl injection These AVMs exhibited cystic radiolucency, with (n = 5) or without (n = 3) honeycombed component. On angiography, all the AVMs exhibited a large intraosseous nidus with multiple suppliers and drainages The intraossous lesions were percutaneously punctured With in 18- to 20-gauge needle, and NBCA diluted 30% to 40% with iodized oil was injected during venous compression Results: Postembolic arteriograms showed that all the AVMs were completely or nearly completely devascularized after single Or multiple injections at the initial treatment. The follow-up period ranged from 3 to 8 years. Two AVMs experienced postembolic curettage and were anatomically cured. Three AVMs were anatomically cured after 1 to 3 sessions of embolotheraphy The other 3 AVMs were clincally cured after 1 (n = 2) to 4 (n = 1) sessions of embolotheraphy. There were no procedure-related severe complications. Conclusions: Direct intraosseous glue embolotherapy can be a simple and safe technique for endovascular management of central AVMs in the jaw and is particularly effective in in emergency. Complete reossification of the intraosseous nidus can be anticipated if a complete occlusion is obtained (C) 2009 American Association of Oral and Maxillofacial Surgeons J Oral Maxillofac Surg 67-2380-2387, 2009http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000271243100010&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Dentistry, Oral Surgery & MedicineSCI(E)PubMed8ARTICLE112380-23876
