To study the angiographic properties of central AVMs in the jaw, and to investigate the efficacy of embolization of them.
Eleven cases of central AVMs underwent angiography and embolization, nine cases experienced surgery after embolization, and the other two cases were embolized alone; all these cases were followed up after treatment. The angiographic features and embolization results were analyzed.
Large venous pouches were angiographically opacified in 9 of 11 AVMs. Of the nine operated cases, curettage was safely performed. The intraoperative bleeding was evidently decreased, and the continuity of the jaw was preserved. Five of these operated cases were free of recurrence during 18 - 27 months in follow-up. The two cases embolized alone were free of recurrence during 24 months' follow-up.
Via arterial and venous approaches, embolization could greatly decrease the intraoperative bleeding and thus help to preserve the continuity and potentiality of development of the jaw for intraosseous AVMs, moreover, it may be curative in some cases.
研究颌骨中心性动静脉畸形（AVM）的血管造影特征，并探讨其栓塞治疗的疗效。
11例颌骨中心性AVM患者接受了血管造影和栓塞治疗，9例在栓塞后接受了手术，另外2例仅接受了栓塞治疗；所有患者在治疗后均进行了随访。分析血管造影特征和栓塞结果。
11例AVM中有9例在血管造影中显示大静脉池显影。在9例接受手术的病例中，均安全地进行了刮除术。术中出血明显减少，颌骨的连续性得以保留。其中5例手术病例在随访的18至27个月内无复发。2例仅接受栓塞治疗的病例在24个月的随访中无复发。
通过动脉和静脉途径，栓塞可大大减少术中出血，从而有助于保留颌骨骨内AVM的连续性和发育潜力，此外，在某些情况下可能具有治愈效果。
