A, Digital subtraction angiography demonstrating the tip of the Licox monitor in the ACA-MCA watershed territory. B, Reconstructed sagittal CT angiogram demonstrates the intraparenchymal location and depth of the fiberoptic Licox cable tip.
- Fig 2.
Prespasmolytic (A) and postspasmolytic (B) cerebral angiograms demonstrating improvement in cerebral vasospasm in ICA, ACA, and MCA vessels after intra-arterial verapamil infusion.

Point plot and column means graph displaying the PbO2 before and after spasmolysis in the mild-to-moderate vasospasm group (A) and moderate-to-severe vasospasm group (B). PbO2 values during the different cerebral angiographies are plotted as points along the y-axis with the mean and SD next to the point plot for both groups. Statistical significance (P < .05) was attained between pre- and posttreatment in both groups.
