We report a case of a frontal dural arteriovenous shunt or fistula (DAVS) adjacent to the left side of the cribriform plate, with bilateral supply from multiple arteries, the most prominent being the dural branches originating from the anterior ethmoidal artery coming from the left ophthalmic artery. Before treatment there was an eight mm flow-related arterial aneurysm proximally on the left ophthalmic artery. After transarterial embolization of the DAVS with N-butyl cyanoacrylate and polyvinyl alcohol, minimal shunting still remained. At follow-up angiography six months after the treatment, the shunt was obliterated and the ophthalmic artery aneurysm had regressed completely. Our case illustrates that complete obliteration of a DAVS may be achieved even though arteriovenous shunting remains at the end of the procedure. Furthermore, a flow-related arterial aneurysm, may not warrant any specific treatment. Elimination of the high flow situation can lead to complete regression of these aneurysms.
我们报告一例位于筛板左侧附近的额部硬脑膜动静脉分流或瘘（DAVS）病例，有来自多条动脉的双侧供血，最显著的是起源于左侧眼动脉的筛前动脉的硬脑膜分支。治疗前，左侧眼动脉近端有一个8毫米的血流相关动脉瘤。在用N-丁基氰基丙烯酸酯和聚乙烯醇对DAVS进行经动脉栓塞后，仍残留少量分流。治疗后6个月的随访血管造影显示，分流已闭塞，眼动脉动脉瘤已完全消退。我们的病例表明，即使在手术结束时仍存在动静脉分流，也可实现DAVS的完全闭塞。此外，血流相关动脉瘤可能无需任何特殊治疗。消除高血流状态可导致这些动脉瘤完全消退。
