硬脑膜动静脉瘘疑诊颞动脉炎一例并文献复习

A case of dural arteriovenous fistula suspected temporal arteritis and literature review

硬脑膜动静脉瘘(DAVF)是颅内动静脉畸形中少见的亚型,占全部颅内血管畸形的10%~15%。其特点是硬脑膜动脉或颅内动脉的硬脑膜支与硬脑膜静脉、脑膜静脉或皮质静脉之间的病理吻合。作者回顾性分析了1例临床疑诊颞动脉炎的头痛患者的临床资料,超声提示“双侧颈外动脉分支-颞浅动脉供血的动静脉瘘可能性大”,经DSA确诊为DAVF。说明在临床工作中,头痛患者除了考虑颞动脉炎外,还应注意排查其他少见引发头痛的疾病。

Dural arteriovenous fistula is a rare subtype of intracranial arteriovenous malformation,accounting for 10%-15%of all intracranial vascular malformations,with the characteristic of pathological anastomosis between the dural branch of the dural artery or intracranial artery and dural vein,or meningeal vein,or cortical vein.In this paper,a patient with headache suspected of temporal arteritis was analyzed retrospectively.Ultrasonography showed that arteriovenous fistula supplied by bilateral branches of the superficial temporal artery of the external carotid artery is likely.Finally,a dural arteriovenous fistula was diagnosed using digital subtraction angiography.The case shows that patients with headaches should also pay attention to other rare diseases causing headaches excepted for the temporal arteritis in practice.
