目的：探讨超声e-flow技术结合梯形成像在下肢交通支静脉功能不全诊断中的作用。方法回顾性分析23例行交通静脉结扎手术患者的超声图像，术前利用超声e-flow技术结合梯形成像检出交通支静脉，将其定位结果与手术结果比较，以检验其准确率。结果下肢交通支静脉功能不全表现为朝向体表的条状或网状血流，超声检出功能不全的交通支静脉47条，手术发现交通支静脉56条，以手术结果为金标准，诊断准确率为83.9%。结论超声e-flow技术结合梯形成像能准确诊断和定位功能不全的交通支静脉，有助于术中寻找需结扎的交通支静脉。

Objective To explore the role of ultrasound-based e-flow technology combined with trapezoidal imaging in the diagnosis of perforating venous insufficiency of lower extremity. Methods The retrospective analysis of preoperative ultrasound images for detection of perforating veins by ultrasound-based e-flow technology combined with trapezoidal imaging was performed in 23 cases with perforating venous ligation in lower extremity. To verify the accuracy of ultrasound images, the positioning of perforating veins using e-flow technology was compared with the operation results. Results Perforating venous insufficiency of lower extremities was shown as ribbon-like strip or reticular flow toward the surface. Forty-seven of incompetent perforating veins were detected by ultrasound, while 56 perforating veins were found by operation. The diagnostic accuracy of ultrasound was 83.9%. Conclusion Ultrasound-based e-flow technology combined with trapezoidal imaging can accurately diagnose and localize the insufficient perforating veins, which is contributed to the localization of perforating veins during the operation of perforating venous ligation.
