上颌部动静脉畸形的PVA栓塞治疗

Embolization in arterovenous malformations of maxillary region with PVA

目的 评价上颌部动静脉畸形的ＰＶＡ 永久性栓塞治疗。方法 ３ 例上颌部动静脉畸形（男１ 例，女２ 例）进行了ＰＶＡ 永久性栓塞治疗。结果 ２ 位患者仅行单次栓塞，１ 位患者行双次栓塞。栓塞后造影，显示异常血管团消失；搏动、杂音也消失；２ 例上颌部明显膨隆的患者栓塞治疗后得到改善。栓塞后至今，未发现有口腔内渗血或出血。栓塞后反应主要表现为肿胀、疼痛、发热，一般持续３ ～７ 天。结论 上颌面部动静脉畸形的ＰＶＡ 栓塞治疗安全、有效。

Objective To evaluate the embolization of arteriovenous malformations of the maxillary region with PVA.Methods 3 cases (male:1, female:2) of arteriovenous malformations of the maxillary region were comprised in this study group. The embolic material used was PVA(Polyvinyl Alcohol Foam) particles (355～500μm) injected through 4.0 to 5.0 French size catheters, catheterized selectively in the feeding pedicles of the AVM under the guidance of DSA machine (PHILIPS V3000). Results Two patients were embolized with a single session, and one patient needed double sessions. Immediate angiographical results showed total disappearance of the AVMs in all patients. Swelling, pulsation, and bruit were disappeared after embolization. Pericoronal oozing and acute arterial bleeding were controllable. Local pain, swelling, and low grade fever usually lated for 3 to 7 days after the embolization.Conclusions The embolization of arteriovenous malformations of the maxillary region with PVA is effective and safe, but the long term efficacy of this therapy remains to be determined.
