The aim of this study was to evaluate correlation between brain tissue oxygen level and transcranial dopplerometry (TCD) parameters in patients with severe subarachnoid hemorrhage (SAH).

Patients and methods:
Patients with subarachnoid hemorrhage from a rupture of cerebral vessel aneurysm and clinical status within the Hunt-Hess scale grade 4 (sopor) or 5 (coma) were enrolled into the study. Brain tissue oxygen monitoring (PbtO2, Licox system) was performed in addition to the standard ICU monitoring that includes TCD. The correlation between TCD and PbtO2 parameters was evaluated.

We enrolled a total of 27 patients, five patients were subsequently excluded for malposition or malfunction of the PbtO2 probe. There was a significant correlation between PbtO2 and both pulsatility index and resistivity index in ± 10 minute (PI: r = –0.4077, p = 0.0074; RI: r = –0.4055, p = 0.0077) and ± 60 minute intervals (PI: r = –0.4145, p =0.0064; RI: r = –0.4089, p = 0.007) with a node point corresponding to TCD measurement. There was no significant correlation between PbtO2 and any of the velocity parameters.

PbtO2 monitoring provides information on brain tissue oxygenation and its microvasculature. However, there is no direct link between PbtO2 values and TCD velocities, the main characteristics of cerebral vasospasm. While we do not know the dynamics between velocities of the main cerebral vessels and PbtO2, the use of both PbtO2 monitoring and TCD seems to be appropriate for follow up of patients with severe SAH in clinical setting.

Key words:
subarachnoid hemorrhage – transcranial Doppler sonography – cerebral vasospasm
