ABSTRACT
Objective To evaluate computed tomography venography (CTV) in diagnosis of iliac vein stenosis or occlusion.Methods From Jun 2015 to Jun 2017,168 CVD patients with CEAP clinically graded at 4 to 6 underwent evaluation with digital subtraction angiography (DSA) CTV and colour Doppler ultrasound.Taking DSA as standard,the diagnostic value of CTV and colour Doppler ultrasound were analyzed and compared.Results DSA established diagnosis of 95 cases,compared with DSA,CTV's and colour Doppler ultrasound's sensitivity,specificity,positive likelihood ratio and negative likelihood ratio was 87.4％ and 64.2％,94.5％ and 98.6％,15.89 and 45.86 and 0.13 and 0.36.Compared with colour Doppler ultrasound,CTV's sensitivity was significantly higher (P ＜ 0.05,the 95 ％ confidence intervals were 0.764-14.257),and there was no significant difference between them in aspect of specificity (P =0.375,the 95％ confidence intervals were 0.943-0.986),Kappa value was 0.809(P ＜0.05,the 95％ confidence intervals were 0.714-0.893),0.597 (P ＜ 0.05,the 95％ confidence intervals were 0.464-0.717).Conclusion In the diagnosis of CVD combined with iliac and femoral venous stenosis,CTV has outstanding sensitivity,specificity,and good conformancy with that of DSA.
