摘要
目的:探讨双源CT血管成像技术对下肢动脉硬化闭塞症患者支架介入治疗后支架管腔评估的应用。方法:对32例因下肢动脉硬化闭塞症置入支架的患者进行双源CT下肢动脉成像,进行容积再现、多平面重组、最大密度投影、曲面重组等处理,观察评价支架管腔的情况。结果:全部患者共检出支架40处,其中髂动脉2处,髂外动脉6处,股动脉24处,腘动脉8处;25处支架通畅,6处支架管腔轻度狭窄,4处支架管腔中度狭窄,3处管腔重度狭窄,2处管腔闭塞。结论:双源CT下肢动脉成像无创、便捷、可靠,可清楚地显示下肢动脉支架形态,通过多种重组方法进行图像处理,观察评价支架管腔内情况,为临床评估术后病情提供可靠依据。
Objective：To discuss the application of stent lumen evaluation of dual source CT angiography in patients with lower limb arteriosclerosis obliterans after stent interventional therapy.Method：Dual source CT angiography of lower extremity were taken on 32 cases with lower extremity arterial occlusive disease of interventional treatment.Volume rendering,multi planar reconstruction,maximum density projection,surface reconstruction and other image processing were used to observe and evaluate the condition of stent lumen. Result：40 brackets were detected out in all patients,2 brackets in iliac artery,6 brackets in external iliac artery, 24 brackets in femoral artery,8 brackets in popliteal arteries;25 stents were unobstructed,6 stents lumen were stenosis mildly,4 stents lumen were stenosis moderately,3 stents lumen were stenosis severely, and 2 stents were blocked.Conclusion：Dual source CT angiography of lower extremity was noninvasive,convenient and reliable, which can clearly show the shape of the lower limb artery stent,image processing by a variety of methods can observe and evaluate the lumen of stent,and can provide a reliable basis for the clinical evaluation of postoperative condition development.
