Pial single-channel arteriovenous (AV) fistulae are usually cured by interrupting only the feeding arteries identified in cerebral angiography.
A 27-year-old woman presented after 3 complex partial seizures due to a pial single-channel AV fistula with the varix located in the right temporal lobe. When all feeding arteries identified by preoperative cerebral angiography were temporarily occluded, varix blood flow was confirmed with Doppler ultrasonography. Many small feeding arteries were identified, and the varix was dissected and removed. The postoperative course was uneventful and postoperative cerebral angiography revealed no abnormal vascular lesions.
Pial single-channel AV fistulae are not always cured by interrupting only the feeding arteries identified in cerebral angiography and might require varix removal.
软膜单通道动静脉（AV）瘘通常仅通过中断脑血管造影中识别出的供血动脉来治愈。
一名27岁女性因右颞叶软膜单通道AV瘘合并静脉曲张出现3次复杂部分性发作后就诊。当术前脑血管造影识别出的所有供血动脉被暂时阻断时，通过多普勒超声证实了静脉曲张的血流。发现了许多小的供血动脉，并对静脉曲张进行了分离和切除。术后过程顺利，术后脑血管造影未发现异常血管病变。
软膜单通道AV瘘并不总是仅通过中断脑血管造影中识别出的供血动脉就能治愈，可能需要切除静脉曲张。
