A comparative study of intravenous thrombolysis and late intracoronary stenting in treatment of acute ischemic stroke onset using 99mTc2ECD SPECT imaging / 中国基层医药

ABSTRACT

Objective To evaluate and compare the therapeutic effect among intravenous rt2PA thrombolysis,thrombolysis plus delayed intracoronary stenting for acute ischemic stroke onset using 99mTc2ECD SPECT imaging.Methods 45 cases of acute ischemic stroke onset were divided into two groups which were the thrombolysis group( n = 23 ) ,thrombolysis plus delayed stenting group (n = 22), 99mTc2MIBI SPECT imaging was performed 3 weeks after thrombolysis therapy or 1 week after intracoronary stenting. The score of 99mTc2MIBI brain uptake were analyzed semiquantitatively and the total score of myocardial 99mTc2ECD uptake was calculated. Results The scores of the 2 groups were( 12. 4 ± 4. 6) and( 9. 7 ± 3. 8 ) respectively, Significant difference was shown in the thrombolysis plus delayed stenting group compared with the thrombolysis group (P ＜ 0. 01 ). Conclusion 99mTc2ECD SPECT imaging had been proved to be an objective parameter for evaluating the therapeutic effect of the various treatments of AMI. Thrombolysis plus delayed stenting was more effective than thrombolysis.
