Application of Contrast Enhance Ultrasound to Evaluate Hemodynamics Change in MCA With Moderate to Severe Stenosis
Recruitment status was: Recruiting
To monitor and evaluate the change of intracranial hemodynamics and MCA stenosis after 24-week atorvastatin treatment using CEUS, CTA and DSA.
Total 30 patients (60 arteries) will be enrolled in this study, who had MCA infarction within 6 months prior to screening, and has not received any statins treatment before stroke.
Eligible patient will receive atorvastatin 40mg treatment for 24 weeks. Hemodynamics changes and MCA stenosis will be evaluated using CEUS at baseline, 3-month,and 6-month. MCA stenosis, bloodstream velocity, as well as clinical symptoms will be assessed at each visit and compared to baseline.

|Official Title:||Application of Contrast Enhance Ultrasound to Evaluate Hemodynamics Change in MCA With Moderate to Severe Stenosis After 24-week Atorvastatin Treatment|
- Hemodynamics changes and MCA stenosis [ Time Frame: given atorvastatin 40mg treatment for 24 weeks ] [ Designated as safety issue: No ]Hemodynamics changes will be evaluaed using CEUS at baseline, 3-month,and 6-month.in order to evaluate the effect of atorvastatin, we will compare the baseline with 3-month,and compare the baseline with 6-month.a statistic analysis of measure data is conducted by the group T test,which conducted by SAS 9.13 English edition .

|Estimated Primary Completion Date:||March 2013 (Final data collection date for primary outcome measure)|
30 patients who had MCA infarction within 6 months prior to screening, and has not received any statins treatment before stroke.in this study ,we will give them atorvastatin 40mg treatment for 24 weeks and monitor and evaluate the change of intracranial hemodynamics after treatment.
40mg per day,duration for 24 weeks
