We assessed lesion growth and neurological improvement (decrease in NIHSS ≥8 points between baseline and 90 days, or a 90-day NIHSS ≤1). Results: 86% of the patients had PDM, but only 41% had CDM. CDM detected PDM with a sensitivity of 46% and a specificity of 86%. We found statistically significant effects of reperfusion on the rate of neurological improvement (OR 9.92, 95% CI 1.91 to 51.64; P<0.01) and on absolute growth (difference: –59.60 mL, 95% CI –95.40 mL to –23.81 mL; P<0.01). Neither treatment with tPA nor reperfusion had a significantly different impact on lesion growth or clinical course in CDM patients compared to patients without CDM. Conclusions: There was no increased benefit from tPA in patients with CDM. The beneficial effects of reperfusion were similar in patients with and without CDM.]]> Sat 24 Mar 2018 10:46:49 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:1980 Sat 24 Mar 2018 08:33:15 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:21405 P=0·03) and a trend to lower absolute growth (-0·17ml versus 9·6ml, P=0·07). Reperfusion was increased in the tissue plasminogen activator group (58% versus 25%, P=0·03) and was associated with increased rates of good neurological (86% versus 28% P<0·001) and functional (modified Rankin scale 0-2 73% versus 34%, P=0·01) outcomes. Reperfusion was strongly associated with lower relative (80% versus 189%, P<0·001) and absolute (-2·5ml versus 40ml, P<0·001) infarct growth. Conclusions: Thrombolysis 4·5-6h after stroke onset reduced infarct growth and increased the rate of reperfusion, which was associated with good neurological and functional outcome.]]> Sat 24 Mar 2018 08:05:00 AEDT ]]>
