1, CT venography ( CTV ) is a non - invasive cerebrovascular imaging technique.

2, Objective:To evaluate the clinical value of anterograde venography of deep vein of lower limb in diagnosing and treating diseases of lower limb veins.

3, Objective:To investigate the value of transcatheter venography through popliteal vein puncture in diagnosis of lower limbs vein disease.

4, Purpose : To explore the value of iliac venography for diagnosing congenital iliac vein compression syndrome . ( CIVCS ).

5, Results: The venography of 18 cases with CIVCS showed that iliac vein was compressed and the collateral venules were formed.

6, Conclusions: CDFI can completely replace the venography in the diagnosis of DVT and it's sequelae.

7, Objective We did intraoperative venography by using methylene blue during varicocelectomy in order to prevent collateral veins ligation omitted and decrease recurrence rate.

8, A new method for venography of lower extremity was designed in which the great saphenous vein was exposed at the medial aspect of the knee.

9, Methods: The imaging findings of ascending venography in 80 sides limb were reviewed retrospectively.

10, Conclusion:We conclude that direct venography is an accurate method of diagnosing and delineating cavernous haemangioma.

11, If the D - dimer test is positive,[http:///venography.html] most PIOPED II investigators recommend CT angiography and CT venography.

12, Methods:From 2003 to 2005, there were 60 cases, totally 65 limbs were carried out anterograde venography of deep vein of lower limb.

13, Methods:13 patients with lower extremity venous disease were accepted for antegrade of venography, the venogram were evaluated.
