[The importance of transcranial doppler ultrasound monitoring for prevention of intraoperative cerebral ischemia].

OBJECTIVE: To determine the possibility of using transcranial ultrasound dopplerography (TCDG) in assessment of unfavorable changes in cerebral blood circulation which lead to the development of intraoperative cerebral ischemia.

MATERIAL AND METHODS: We studied 55 patients who underwent vascular surgery or neurosurgical interventions. Changes in the systemic hemodynamics of ischemic character were recorded during the surgery in all patients. To assess the state of cerebral blood circulation, we performed TCDG using a special system of monitoring.

RESULTS: Intraoperative TCDG monitoring showed the absence of critical changes in cerebral blood circulation (cerebral blood flow).

CONCLUSION: Complex preoperative and intraoperative ultrasound diagnosis gives the possibility to prevent intraoperative injuries of the brain.
