超声影像在深静脉血栓形成介入综合治疗中的应用

目的探讨二维及彩色多普勒超声在深静脉血栓形成患者介入综合治疗中的应用。方法对17例疑为深静脉血栓形成患者行术前超声诊断及评估,后接受血管造影并行下腔静脉滤器及支架植入术,彩色多普勒超声于术后复查,观察滤器及支架位置、形状、及血流通畅情况。结果17例患者下腔静脉滤器植入12枚,静脉内支架植入10枚。所有移植物超声图像均可清晰显示,支架及滤器主干表现为静脉管腔内平行线状强回声,术后复查10枚滤器及9枚支架均塑形良好,血流充盈良好。2枚滤器及1枚支架分别于术后继发血栓形成,超声表现为滤器强回声管腔内出现密集实性暗淡光点充填,血流充盈不良。结论超声影像技术对静脉血栓患者介入治疗的术前评价及术后随访有重要价值,可作为首选检查方法。

Application of Ultrasonography in Interventional Therapy of Deep Venous Thrombosis

Objective To approach the application method of two-dimensional and color Doppler ultrasonography in interventional therapy of deep venous thrombosis. Methods Seventeen patients doubted as deep venous thrombosis underwent ultrasonic diagnosis and follow up evaluation before or after interventional therapy of filter and/or stent implantation. Position, shape and blood flow circulation of the filter and stent were observed on color Doppler ultrasonography. Results Total of twelve filters and 10 stents were implanted in 17 patients. All of the grafts were displayed clearly on ultrasonography which showed hyper echoic parallel line in the venous lumen. In the follow-up study, ten filters and 9 stents showed well-shaped and well-filled with color flow. Thrombogenesis was found in 2 filters and 1 stent, which displayed close-up solid light spot in the metal like hyerechoic lumen, with poorfilled blood flow on color Doppler ultrasonography. Conclusions Ultrasonography could be of great value and first choice method in interventional therapy of deep venous thrombosis.
