Critical Closing Pressure of Cerebral Circulation at Concomitant Moderate-to-Severe Traumatic Brain Injury.

Background: Critical closing pressure (CrCP) is the pressure below which local pial blood pressure is inadequate to prevent blood flow cessation. The state of cerebral CrCP in patients with concomitant moderate-to-severe traumatic brain injury (cTBI) after brain lesions surgery remains poorly understood.

Aim: The aim of our study was to establish the dynamics of CrCP after intracranial surgery in traumatic brain injury (TBI) patients with polytrauma.
