Changes in cerebral hemodynamics in boxers with repeated traumatic brain injury.

UNLABELLED: There are currently insufficient study and analysis of changes in cerebral hemodynamics of boxers who have suffered repeated traumatic brain injury (TBI). To identify such changes, the most informative is the study of blood flow in the vessels of the neck and head using ultrasound duplex scanning (USDS) of the main vessels of the neck and transcranial duplex scanning (TCDS).

AIM: The aim of study was to investigate the features of cerebral hemodynamics in boxers with repeated TBI.

MATERIALS AND

METHODS

A study of blood flow in the vessels of the neck and head was performed for 156 amateur boxers aged 16 to 42 years who had a history of repeated TBI. In the control group, 30 practically healthy people of a similar age were examined. Patients were analyzed by gender and the number of fights held. Obtained results were analyzed statistically.

RESULTS

Boxers who have had a history of repeated TBI have hemodynamic disorders. They are characterized by an increase in the velocity of blood flow in extracranial vessels of the carotid basin and a decrease in the vessels of the vertebrobasilar basin with a change in the indicators of vascular resistance. For vessels of the intracranial section of the carotid basin, a decrease in blood flow velocity without changes in the indicators of vascular resistance was typical. Disorders of venous cerebral circulation was noted in most boxers, which was manifested by an increase in speed indicators in the internal jugular vein and veins of Rosenthal.

CONCLUSIONS

The study of features of the cerebral hemodynamic in boxers with repeated TBI allows them to predict their competitive activity, correctly select the appropriate therapy and recommendations of the sports regime to prevent possible long-term consequences of injury.
