摘要
目的:支架置入在下肢深静脉血栓的应用取得了良好效果,但由于支架作为一种异物,置入后可能导致再次血栓形成及血管内再狭窄,本文通过彩色多普勒超声观察血栓形成后的静脉血流通过情况,以了解彩色多普勒超声对支架置入后血管内再狭窄及血流动力学的评价作用。方法:利用彩色多普勒二维超声观察深静脉的静脉管径、管腔内回声、彩色血流充盈情况及支架置入治疗后管腔内回声、支架内的血流变化,详细记录静脉管径大小,内膜的改变,血栓形成的部位、范围。结果:髂股静脉血栓形成35例,25例进行支架置入,支架置入后血流通畅,预后良好18例,再次血栓形成7例。结论:彩色多普勒图像直观清晰,与X线造影相比更安全无创,检查方便,费用相对低廉,清楚显示血栓,动态评估预后疗效,及时发现再次血栓形成,既准确又方便快捷。
AIM： Stenting is an effective therapy for deep venous thrombus of lower limbs. However, as a foreign body, the stent can cause recurrence of thrombogenesis, resulting in intravascular restenosis. This study observed vein blood flow using color Doppler ultrasound to explore the role of color Doppler ultrasound in evaluating intravascular restenosis and hemodynamics after stenting. METHODS： Venous diameter, intraluminal echo of deep vein, color blood filling and changes after stenting and in-stent blood flow were observed using color Doppler two-dimensional ultrasound. In addition, venous diameter, intima changes, site and scope of thrombus were recorded. RESULTS： Of 35 cases of thrombus in iliofemoral vein, 25 were treated with stenting, whose blood flow was parent after stenting, and 18 exhibited good prognosis, while 7 developed recurrence of thrombogenesis. CONCLUSION： Color Doppler ultrasound has clear images. It is safer, more convenient, and economic compared with radiographs. Moreover, it can dynamically evaluate prognosis, and display recurrence of thrombogenesis.
