【摘要】 目的:探讨64排MSCT肺动脉与下肢深静脉联合扫描对静脉血栓栓塞病的诊断价值,以提高64排MSCT肺动脉和下肢深静脉联合成像技术及诊断水平。方法:收集了43例确诊肺动脉栓塞行肺部及双下肢64排MSCT血管成像和数字减影血管造影(DSA)检查的患者,并采用双盲法对64排MSCT的诊断及DSA的诊断的结果进行图像分析。结果:43例临床确诊肺动脉栓塞的患者中,肺动脉血栓形成的64排MSCT血管成像表现有:栓子位于血管中央者(17例);栓子附着于管壁一侧者(23例);栓子基本完全阻塞者(3例)。其中,38例双下肢深静脉栓塞者64排MSCT血管成像表现有:静脉充盈缺损(23例);静脉闭塞和中断(8例);侧支循环形成(7例)。结论:64排MSCT肺动脉与下肢深静脉的联合扫描对静脉血栓栓塞病有一定诊断价值。更多还原

【Abstract】 Objective:To evaluate the diagnostic value of 64-slice MSCT angiography for venous thromboembolic disease,to improve MSCT pulmonary artery combined with deep venous imaging technology and diagnostic levels.Methods:Collected 43 cases of confirmed pulmonary embolism underwent lung and lower extremity 64-slice spiral CTA angiography and DSA,and blinded to diagnosis of 64-slice spiral CTA and diagnostic results of the DSA image analysis.Results:43 cases of clinically diagnosed pulmonary embolism in patients with pulmonary arterial thrombosis 64-slice spiral CTA performance:emboli in the vascular central(17 cases);embolus attached to the wall side(23 cases);the emboli basic obstruction(3cases).38cases lower limbs deep vein thrombosis MSCTA performance:venous filling defect(23cases);vein occlusion and interruption(8cases);the formation of collateral circulation(7cases).Conclusion:MSCT angiography of acute pulmonary embolism and deep venous thrombosis,the formation of some diagnostic value.更多还原
