OBJECTIVE
We treated a case of scalp arteriovenous malformation (sAVM) by transvenous embolization using Onyx.
CASE PRESENTATION
We describe the case of a 17-year-old woman with a pulsatile mass at the right temporal area. DSA identified sAVM with the venous pouch between the right occipital artery (OA) and the right two occipital veins (OVs), which was also fed by multiple branches of the right posterior auricular artery (PAA) and superficial temporal artery (STA). The shunts were completely occluded by the reverse pressure cooker technique (RPCT), which involves navigating the balloon catheters just distal to the shunt point in the OVs approaching from the right external jugular vein (EJV) and injecting Onyx to each feeder retrogradely with balloons inflated.
CONCLUSION
This technique may be useful for treating sAVM with venous angioarchitecture enabling a transvenous approach.
目的
我们使用Onyx通过静脉栓塞治疗了一例头皮动静脉畸形（sAVM）。
病例介绍
我们描述了一名17岁女性患者，其右侧颞部有一搏动性肿块。数字减影血管造影（DSA）确定为sAVM，静脉囊位于右枕动脉（OA）和右枕静脉（OV）两支之间，同时由右耳后动脉（PAA）和颞浅动脉（STA）的多个分支供血。通过反向压力控制技术（RPCT）完全闭塞分流，该技术包括将球囊导管置于从右颈外静脉（EJV）进入的OV中分流点的远侧，在球囊充气的情况下向每个供血支逆行注射Onyx。
结论
该技术对于治疗具有静脉血管结构且可经静脉入路的sAVM可能有用。
