Effects of the cervical maneuvers in the vertebral extracraneal arterial flow in patients with vertebrobasilar failure
Keywords:
vertebrobasilar failure, cervical rotation maneuver, final diastolic speed, blood flow, secondary health care.Abstract
A quasi-experimental study of 52 patients with vertebrobasilar failure, assisted in "Dr. Juan Bruno Zayas Alfonso" Teaching General Hospital in Santiago de Cuba was carried out from September to March, 2014, in order to determine the effects of the cervical rotation maneuvers in the blood flow at the level of the extracraneal vertebral arteries. Among the analyzed variables there were: age, sex, maneuver of cervical rotation and final diastolic speed. The mean and proportions were used as summary measures, as well as the Friedman statistical Chi squared test, with a significance level of 0,05. The 45-54 years affected patients prevailed in both sexes. The cervical rotation maneuvers led to a decrease in the final diastolic speed of the vertebral arteries and reduced the extracraneal vertebral arterial blood flow.
