脑动静脉畸形所致癫痫的治疗进展

脑动静脉畸形（AVMs）是一种复杂的血管病变，其特点是动脉血直接流入引流静脉，没有流经毛细血管床。通常缺乏小动脉和毛细血管产生的阻力，除了脑血管的解剖结构发生改变外，脑血流动力学也会出现显著改变。癫痫是该病的第二大临床表现，占诊治AVMs的20%～45%，癫痫会给患者带来一系列的问题，现将其新研究进展做一综述。

Progress in the treatment of epilepsy caused by cerebral arteriovenous malformations

Cerebral arteriovenous malformations (AVMs) are complex vascular lesions characterized by arterial blood directly flowing into the draining vein and bypassing the capillary bed. Due to the lack of resistance from arterioles and capillaries, both cerebrovascular anatomical structure and cerebral hemodynamics can change significantly. Epilepsy is the second major clinical manifestation of AVMs, which accounts for 20%~45% of all cases, and brings a series of problems to patients. Here we review the advances in the treatment of epilepsy caused by AVMs.
