Fig. 3From: Cerebral collateral circulation in experimental ischemic strokeRelationship between cerebral collateral flow during MCAO and stroke outcome in rats. Linear regression between infarct volume and perfusion deficit during MCAO in the territory of leptomeningeal collaterals, measured using multi-site laser Doppler, was calculated for 45 consecutive untreated rats (p < 0.0001; Pearson’s r = −0.59). Notably, the correlation between infarct volume and perfusion deficit in the ischemic core (central MCA territory) was not significant (p = 0.14, smaller graph)Back to article page
