摘要
目的探讨超声自动容积断层成像系统(AVSS)在下肢静脉曲张中的应用价值。方法分别对32例患者、45条下肢曲张静脉进行传统矢状面横切、纵切扫查和超声自动容积断层扫描,获得容积成像信息,观察并重点对表皮冠状面图像进行研究分析。结果自动容积断层扫描显示45条曲张下肢静脉中,35条为单纯静脉曲张,7条合并瘤样扩张,5条伴有节段性静脉血栓形成,其中2条同时伴瘤样扩张和静脉血栓形成,病变均在AVSS表皮冠状面成像上清晰显示。AVSS纡曲静脉检出率明显高于二维灰阶超声(P<0.001)。结论超声AVSS可以整体直观评估下肢静脉的发病情况,结合传统彩色超声判断静脉瓣功能可为术前提供重要信息。
Objective To explore the application value of automated volume scanner system(AVSS) in varicose vein of lower limbs.Methods AVSS and 2D gray-scale ultrasonography were used to examine 45 varicose veins of lower limbs in 32 patients,and the features were analyzed in transactional and sagittal plane of the traditional gray-scale images,especially in skin-coronal plane patterns after obtaining the full volume images.Results AVSS clearly indicated the characteristics of 45 varicose veins of lower limbs in skin-coronal plane patterns,including 35 simple varicose veins,7 varicose veins with aneurysmal dilatation,5 with segmental venous thrombosis and 2 with both aneurysmal dilatation and segmental venous thrombosis.The detection rate of circuitous veins with AVSS was significantly higher than that with 2D gray-scale ultrasonography(P0.001).Conclusion AVSS can intuitively evaluate the development of the lower limb veins,and judge the function of venous valves combining traditional color Doppler flow image,which can provide important preoperative information.
