Insertion site and trajectory of ptO2 probes according to vascular territory
| ACA | Watershed | MCA | p value* | |
|---|---|---|---|---|
| Midline (cm) | 3.79 (± 0.92) | 3.55 (± 1.73) | 4.05 (± 0.72) | 0.934 |
| Coronal suture (cm) | 1.93 (± 0.60) | 2.24 (± 1.30) | 1.90 (± 1.03) | 0.922 |
| Sagittal (degrees) | 86.70 (± 13.44) | 55.87 (± 22.24) | 42.89 (± 19.39) | 0.107 |
| Coronal (degrees) | 41.70 (± 8.49) | 22.23 (± 21.00) | 28.15 (± 13.37) | 0.392 |
Location of the cranial entry point and trajectory of the ptO2 probes for different vascular territories. Mean± standard deviation is given for all values. The location of the entry points is given as distance from the midline in a coronal plane as well as distance from the coronal suture in the sagittal plane. The trajectories are given in degrees angulation in a sagittal projection with reference to the Frankfurt horizontal plane as well as in a coronal projection with reference to the midline
ACA Anterior cerebral artery territory, Watershed Watershed zone between the anterior and middle cerebral artery territory, MCA Anterior portion of the middle cerebral artery territory, cm Centimeter.* Kruskal–Wallis test
