摘要
目的探讨多层螺旋CT静脉造影(MSCTV)及DSA静脉造影在诊断髂静脉受压综合征(IVCS)及继发血栓形成中的临床应用价值。方法收集38例临床可疑IVCS患者的MSCTV及溶栓治疗前后DSA图像数据,测量MSCTV图像中受压髂静脉的前后内径,计算受压程度,并采用列联表卡方检验比较MSCTV及溶栓治疗前后DSA对IVCS的检出率差异。结果 MSCTV发现IVCS 29例,DSA在溶栓治疗前发现IVCS 20例,溶栓治疗后发现IVCS 29例。MSCTV与溶栓前DSA对IVCS的检出率差异有统计学意义(χ2=4.65,0.01<P<0.05),MSCTV与溶栓后DSA对IVCS的检出率差异无统计学意义(χ2=0.00,P>0.05)。结论在IVCS诊断中,MSCTV的准确性明显优于溶栓治疗前DSA检查,可作为IVCS诊断的首选检查。
Objective To evaluate multi- slice spiral CT venography(MSCTV) and digital subtraction venography(DSV) in diagnosing iliac vein compression syndrome(IVCS) and secondary thrombosis. Methods The imaging materials, including MSCTV and DSV performed before and after the thrombolysis therapy, of38 patients with clinically- suspected IVCS were collected. The inner diameters of the compressed iliac veins were measured on MSCTV images and the compression ratio was calculated. Using χ^2test, the detection rates of IVCS by MSCTV and DSV were compared. Results Of 38 patients, IVCS was detected by MSCTV in 29,by pretreatment DSV in 20 and by post- treatment DSV in 29. The difference in the detection rate of IVCS between MSCTV and pre- treatment DSV was statistically significant(χ2=4.65, 0.01 P〈0.05), while the difference in the detection rate of IVCS between MSCTV and post- treatment DSV was not significant(χ^2=0.00, P〉0.05). Conclusion For the diagnosis of IVCS, MSCTV is superior to pre- treatment DSV in the diagnostic accuracy of iliac vein compression syndrome. Therefore, MSCTV should be used as the preferred method of examination.
