Changes in сerebral hemodynamics in patients with severe traumatic brain injury after surgical decompression

Abstract

A prospective study of 16 patients with severe TBI and traumatic brain edema who had undergone decompressive craniectomy (DC) with dura opening was carried out. Directly before surgical intervention and afterwards, TCDG was used to measure blood flow linear velocity (BFLV) in the middle cerebral artery (MCA) in both hemispheres and in extracranial segments of internal carotid artery (ICA). BFLV increase in MCA and ICA both on the side of surgery and the opposite side was determined. The difference between average BFLV growth in MCA on the side of decompression and the opposite side was statistically significant (P<0.05). MCA and ICA pulsatility index (PI), both on the side of surgery and the opposite side, decreased. PI decrease in MCA was significantly greater on the side of decompression than on the opposite side (P<0.05).
