硬膜动静脉畸形(DAVM)常见于横窦和乙状窦,占颅内血管畸形的10％～15％。一般认为与继发性硬膜窦血栓形成有关,也注意到与静脉引流受阻有关。治疗方法多采用超选择经导管栓塞。作者经枕动脉直接穿刺栓塞1例硬膜窦瘘,病人80岁,主诉听力下降、耳鸣、头痛渐加重6个月。CT增强检查显示横窦与乙状窦区的硬膜呈弥漫性强化,枕动脉十分清楚。脑血管造影证实为广泛性硬膜动静脉畸形,主要由扭曲扩张的枕动脉供血,也可见到脑膜中动脉和椎动脉后脑膜支供血。考虑到病人年龄较大,栓塞大多数来自枕动脉的供应血管即可解除临床症状。病人俯卧,枕部备皮,触摸枕动脉搏动明显点,用21号蝶型穿刺针刺入枕动脉,注射
Dural arteriovenous malformations (DAVM) common in the transverse sinus and sigmoid sinus, accounting for intracranial vascular malformations 10% to 15%. It is generally believed that with the secondary dural sinus thrombosis, also noted that venous drainage is blocked. Treatment methods and more use of transcatheter embolization. The author directly puncture the occipital artery embolism in 1 case of dural sinus fistula, the patient 80 years old, chief complaint hearing loss, tinnitus, headache gradually increased 6 months. CT enhanced examination showed diffuse dura mater transverse sinus and sigmoid sinus was enhanced, the occipital artery is very clear. Cerebral angiography proved to be extensive dural arteriovenous malformations, mainly by the twisted dilated occipital artery, can also be found in the meningeal artery and vertebral artery blood supply to the meninges. Given the age of the patient, embolization of most of the blood supply from the occipital artery relieves the clinical symptoms. Patient prone, occipital skin preparation, touch the occipital artery pulsation obvious point, piercing the occipital artery with a 21-gauge butterfly needle, injection
