调研两广地区（广东省和广西壮族自治区）颈动脉狭窄超声诊断符合率、广东省肾动脉狭窄超声诊断符合率及血管超声危急值管理现状，依据调研结果制定科学化、精细化、可落地的质量改进措施，为提升血管超声诊断质量提供依据。

收集两广地区不同层级医院（广西壮族自治区26家、广东省33家）2023—2024年颈动脉狭窄超声诊断数据、广东省63家医疗机构肾动脉狭窄超声诊断数据及68家医疗机构血管超声危急值管理数据，进行回顾性分析。

两广地区颈动脉狭窄超声诊断符合率均呈上升趋势，广东省由2023年的85.4%（2990/3501）同比提升至88.2%（2247/2549），绝对增幅为2.8%；广西壮族自治区由2023年的79.1%（1078/1362）提升至81.8%（1759/2151），绝对增幅为2.7%，广东省进步更为突出。广东省肾动脉狭窄超声诊断存在数据填报不规范问题，有效数据比例仅为39.7%（25/63），还有部分医疗机构未采用指南推荐标准进行诊断。广东省血管超声危急值报告及时性良好（100%），但存在报告和图像留取不完整等情况，报告完整率为89.8%（778/866），图像完整率为86.1%（746/866）。

针对调研中发现的问题，需通过制定统一标准、加强系统质量控制及精准培训等措施，进一步提升血管超声诊断的准确性和规范性。

To investigate the ultrasound diagnostic concordance rates for carotid artery stenosis in Guangdong Province Guangxi Zhuang Autonomous Region, as well as for renal artery stenosis in Guangdong Province, to evaluate the current management status of vascular ultrasound critical values, and to develop scientific, refined, and actionable quality improvement measures grounded in the survey findings, with the aim of providing a foundation for enhancing the overall quality of vascular ultrasound diagnosis.

A multicenter retrospective analysis was conducted using 2023–2024 ultrasound data. The dataset included carotid artery stenosis data from 26 hospitals in Guangxi and 33 hospitals in Guangdong, renal artery stenosis data from 63 medical institutions in Guangdong, and vascular ultrasound critical value management data from 68 medical institutions.

The ultrasound diagnostic concordance rate for carotid artery stenosis showed an upward trend in both regions. In Guangdong Province, the rate increased from 85.4% (2990/3501) in 2023 to 88.2% (2247/2549), representing an absolute increase of 2.8%. In Guangxi, the rate rose from 79.1% (1078/1362) to 81.8% (1759/2151), with an absolute increase of 2.7%, with Guangdong showing somewhat greater improvement. For renal artery stenosis in Guangdong, data entry non-compliance was identified: only 39.7% (25/63) of institutional datasets were deemed valid, and some institutions had not adopted the recommended guidelines. Regarding vascular ultrasound critical value reporting in Guangdong, timeliness was satisfactory (100%), but incomplete reporting and incomplete image retention were noted. The completeness rate for reports was 89.8% (778/866), and that for images was 86.1% (746/866).

Given the issues identified in this survey, we recommend implementing unified diagnostic criteria, systematic quality control procedures, and targeted professional training to further improve the accuracy and standardization of vascular ultrasound diagnosis.
