1 Experimental study on the effect of antegrade cerebral perfusion on brains with old cerebral infarction  Naoki Washiyama, MDa, Teruhisa Kazui, MDa, Makoto Takinami, MDa, Katsushi Yamashita, MDa, Syouji Fujita, MDa, Hitoshi Terada, MDa, Kazuchika Suzuki, MDa, Bashar A.H.

2 Fig. 1 Angiography after injection of silicone cylinder embolus. Nonvisualization of the left MCA indicates that the cylindrical silicone embolus was in a proximal location in the left MCA.

3 Fig. 2 Levels of venous-arterial lactate difference. Levels in the infarct group at 32°C are significantly higher than those in the control group (P <.01). Error bars indicate SEs. Numbers along the horizontal axis are defined as follows: 1 , 5 minutes after initiation of extracorporeal circulation; 2 , when rectal temperature reached 20°C; 3 , 60 minutes after initiation of SCP; 4 , 120 minutes after initiation of SCP; 5 , when rectal temperature reached 24°C; 6 , when rectal temperature reached 28°C; 7 , when rectal temperature reached 32°C; and 8 , when rectal temperature reached 36°C.

4 Fig. 3 Levels of precooling and postrewarming serum glutamate in the 2 groups. In the postrewarming phase levels in the infarct group were significantly higher than those in the control group (P =.03). Bars show 95% confidence intervals. Blood samples for measurement of serum glutamate were obtained from the venous cannula on occasion 1 and occasion 8, as defined in the legend for Figure 2.

5 Fig. 4 Coronal section of brain in the infarct group showing the infarction in the left basal nuclei on hematoxylin and eosin staining. No extravasation of Evans Blue dye is seen.
