Abstract: 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 96.49% (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.
