摘　　要：目的 探讨直接法下肢CT静脉造影（ CTV）在诊断下肢深静脉血栓（DVT）中的应用价值。方法 回顾性分析57例下肢DVT患者的直接法下肢CTV的影像资料，与下肢静脉X线数字减影血管造影（DSA）进行对照。结果 直接法下肢CTV共检出55例，63处下肢DVT，诊断阳性率96.49%（55/57）。其中周围型23例，中央型19例，混合型23例。影像表现为静脉闭塞、中断、充盈缺损，8例可见侧支循环建立。结论 直接法下肢CTV可以清楚地显示下肢DVT的位置、大小、形态，而且检查操作简便、安全，对比剂用量少，是诊断DVT的重要方法之一。Objective To discuss the diagnostic value of direct computed tomography venography {CTV） in lower extremity deep venous thrombosis （DVT）.Methods The image data of 57 lower extremity DVT cases examined by direct CTV were analyzed retrospectively,and compared with X-ray digital subtraction angiography （DSA）.Results 55 cases with 63 DVT of lower extremity veins were detected by direct CTV.The positive rate of diagnosis of direct CTV was 96.495 （55/57）.23 cases were peripheral type, 19 cases central type, 23 cases mixed type.The imaging findings of DVT in direct CTV were the blocked or discontinued vein and filling defection, collateral circulation was showed in 8 cases.Conclusion Direct CTV may show the position,size and shape of the DVT,and is simple,safe and less contrast agent, which is one of the important method of DVT diagnosis.
