摘　　要：目的:探讨DSA图像测量技术在缺血性脑血管病介入检查及治疗中的应用价值。方法:对我院介入中心近期100例缺血性脑血管病血管狭窄患者在全脑血管造影检查及介入治疗过程中,应用DSA图像测量技术对狭窄血管进行测量并进行狭窄百分比分析计算。结果:应用DSA图像测量技术对本组病例中的血管狭窄病变进行测量,应用直径为10mm的正圆形不锈钢球作为参照物,并且尽可能将其放置在与预测量血管或病变同侧同一平面位置接近的部位,其测量数值与实际大小非常接近;对于颅外段狭窄病变,可以应用带有标准刻度(mm为单位)的导管或导丝作为参照物,进行测量时很少产生误差。结论:DSA图像测量技术对缺血性脑血管病检查及治疗具有重要的指导意义,能够正确评价血管的狭窄程度,对于介入操作医生选择合适的支架、保护过滤伞及扩张球囊等材料的种类、型号至关重要。Objective：To evaluate the usefullness of the DSA measuring technique in intervenfional treatment of ischemic cerebrovascular disease. Methods： One hundred cases with isehemic cerebrovascular disease were studied with digital subtraction angiography in Xuanwu hospital. Dianleters of both the diseased vessels and normal vessels in the same patient were measured using the DSA measuring technique. Results：Using a small metal ball with the diameter of 10 mm as callibrating object,the target vessels was then measured.To accurately measure tile diameter of the vessels,the metal ball should be put in or near the same plane as the diseased or target vessels.To accurately measure the diameter of the vessels, it is also feasible to use the catheters or wires with marker as calibrating objects. Conclusion： The DSA measuring technique is extremely important for ischemic cerebrovaseular disease in study and treatment. It is essential to choose the right size and type of stents, protection devices and angioplasty balloons according to the result of DSA measurement.
