脑卒中发病率、病死率、复发率、致残率均较高，社会负担较重，为改善这种状况，2011年国家卫生健康委员会成立国家脑卒中防治工程委员会（简称脑防委）。2016年脑防委发布卒中中心建设工作计划，脑颈血管超声工作是其重要组成部分，其在脑卒中高危人群筛查、动脉粥样硬化性病变诊断、重症监护、卵圆孔未闭、微栓子监测、颈动脉手术术前评估术中监护术后随访等方面发挥着重要作用。然而由于起步较晚，脑颈血管超声工作同质化水平低，不同医疗机构之间的条件和水平相差较大，部分医院的相关工作难以满足临床及患者需求。因此，笔者依据脑防委卒中中心建设相关标准，收集参与现场评估的21家三级医院、32家二级医院卒中中心脑颈血管超声检查的共性问题，提出整改方案，以期改善脑颈血管超声的诊断质量，提升卒中中心建设水平。

The morbidity, mortality, recurrence , and disability of the stroke are increasingly high, and the social burden is correspondingly heavy. To change this situation, the Ministry of Health established the National Brain Prevention Committee (SPTPC) in 2011. SPTPC released the project plan about the stroke center construction in 2016. Carotid cerebrovascular ultrasound is one of the important parts of the stroke center construction. It plays an significant role in identifying patients with the high stroke risk, diagnosing atherosclerotic diseases, intensive care ward, diagnosing patients with patent foramen ovale (PFO), monitoring microemboli, preoperative evaluation, intra-operative monitoring, and follow-ups of the carotid endarterectomy(CEA). However, due to the limited construction period, the homogenization level of carotid cerebrovascular cltrasound was low, and the conditions and levels among different medical institutions were quite different. The capacity of several hospitals was difficult to meet the clinical and patient needs. Therefore, according to the relevant SPTPC standards of the stroke center construction , the authors collected and analyzed the common issues of carotid cerebrovascular ultrasound in 21 tertiary hospitals and 32 secondary hospitals that participated in the on-site evaluation. The authors put forward the improvement plan, with a view of improving the quality of diagnosis by carotid cerebrovascular ultrasound and the construction level of stroke centers.
