We present here an interesting case of multiple dural arteriovenous shunts (dAVS) in different locations at the same time. There have been very few reports on multiple dAVS. A 63-year-old man was admitted with a sudden onset of headache and vomiting. CT scan showed a typical subarachnoid hemorrhage (Fisher Group 3). Cerebral angiogram (6 vessel study) revealed two dural arteriovenous shunts at the same time. One was located on the anterior fossa fed by the anterior ethmoidal artery, and the other was located on the posterior fossa near the marginal sinus fed by the left ascending pharyngeal and occipital arteries. At first, transarterial embolization was performed for dAVS located on the posterior fossa. Radical operation was performed for both anterior and posterior fossa dAVS. Both dAVS had disappeared on postoperative angiograms.
我们在此呈现一例有趣的病例，患者同时在不同部位出现多处硬脑膜动静脉分流（dAVS）。关于多处dAVS的报道非常少。一名63岁男性因突发头痛和呕吐入院。CT扫描显示典型的蛛网膜下腔出血（Fisher 3级）。脑血管造影（六血管检查）同时发现两处硬脑膜动静脉分流。一处位于前颅窝，由筛前动脉供血；另一处位于后颅窝，靠近边缘窦，由左咽升动脉和枕动脉供血。起初，对位于后颅窝的dAVS进行了经动脉栓塞。对前、后颅窝的dAVS均进行了根治性手术。术后血管造影显示两处dAVS均消失。
