Presumed venous drainage path according to ICH locationa
| ICH locationb | Presumed Venous Drainage |
|---|---|
| Frontal lobes | Superior sagittal sinus |
| Superior parietal lobes | Superior sagittal sinus |
| Inferior parietal lobes | Transverse or sigmoid sinusc |
| Occipital lobes | Superior sagittal sinus |
| Temporal lobes | Transverse or sigmoid sinusc |
| Peri-Sylvian cortex | Cavernous sinusc |
| Insular cortex | Cavernous sinusc |
| Basal ganglia | Internal cerebral veins,c vein of Galen, straight sinus |
| Thalami | Internal cerebral veins,c vein of Galen, straight sinus |
| Cerebellar vermis | Vein of Galen, straight sinus |
| Cerebellar hemispheres | Transverse or sigmoid sinusc |
| Brain stem | Superior petrosal sinusc |
a Adapted from Meder et al13 for the supratentorial brain and Jinkins14 for the infratentorial brain. Note that there may be considerable variability in the venous drainage pattern of the cortical supratentorial brain.
b The frontal, temporal, and parietal lobes exclude the peri-Sylvian cortex within these lobes.
c Ipsilateral to the ICH location.
