The Showing and Curative Effect Assess of the Color Doppler flow Imaging in Different Periods of Deep Vein Thrombus in Legs

Objective Application of color doppler ultrasound(CDFI) detection of the lower limbs of deep vein thrombosis(DVT) for the clinical stages,by the early identification and early treatment,reduce the incidence of pulmonary embolism or by the sudden death of pulmonary artery thrombosis cause blood clots and post-thrombotic syndrome. Methods Choose the 40 patients from the January of 2010 to the August of 2011.They are all the patients checked by CDFI and DSA,and diagnosed the patients who are vein thrombus in legs,including acute thrombus,subacute thrombus and chronic thrombus.Obserse the pictures of Color Doppler Flow Imaging. Results The showing of two dimensions color supersonic wave and the showing of CDFI has typical sound wave.The results after treating are different.The result of early acute thrombus(flowing back is not easy)is the best.The thrombus can be dissolved less than one month.The thrombus of the middle period and later period can be dissolved in 3 months.But the thrombus of subacute needs 3～6 months or more than 6 months to dissolve most of the thrombus.But we can still see the thrombus among the patients of the thrombus of the middle period and later period.We can see the organization echo wave of thrombus after 10 years in the chronic thrombus patients. Conclusion The treatment on acute thrombus patient is the best.The treatment on subacute thrombus patients is the second.The treatment on chronic thrombus patients is the worst.
