Ultrasound is used in the diagnosis, treatment and follow-up of cerebral arteriovenous malformation (AVM). Several parameters including flow velocity, flow volume, resistance index, pulsatility index, vasomotor reactivity and their influencing factors are reviewed. The applications of ultrasound in the preoperative evaluation, intraoperative monitor and postoperative follow-up of AVM, are summarized. Although some limits exist, ultrasound can provide more reliable information about AVM, if lesions are classified according to their characteristics, compared in different conditions between preoperation and postoperation, feeding and non-feeding side, patients and healthy adults, and if ultrasound method is combined with other examinations and different developed ultrasound techniques. With the appearance and development of new ultrasound technique, its application will be wider in management of AVM.
超声技术常应用于脑动静脉畸形诊断、 治疗以及随访。 本文回顾了用超声技术测量脑血맜血流速度、 流量、 脉搏指数、 阻力指数、 血맜反应性等指标以及其相关影响因素, 总结了超声技术在脑动静脉畸形的术前评估、 术中监测以及术后随访中的应用。 尽맜超声技术目前不能作为脑动静脉畸形的筛选手段, 但是, 如果根据脑动静脉畸形病变特性分组选择检查方法, 对比患者在手术前、 后, 供血侧与非供血侧以及患者与健康人群之间的检查结果, 配合其它检查手段以及不同的超声成像技术, 超声技术则能提供更为可靠的诊断信息。 随着新的超声技术的出现和发展, 超声在动静脉畸形方面的应用会更加广泛。
