Summary

Dynamic computerized tomography (DCT) aids in diagnosing vertebral and basilar artery blood flow disturbances caused by atherosclerosis. DCT abnormalities were found in 90% of stabilized syndrome patients and 40% of transient ischemia patients.

Area of Science:

  • Neurology
  • Vascular Medicine
  • Radiology

Background:

  • Vertebrobasilar artery disturbances result from atherosclerotic lesions causing stenosis or occlusion.
  • Clinical manifestations range from transient vertigo to stabilized syndromes with brain damage.

Purpose of the Study:

  • To assess vertebrobasilar blood flow using dynamic computerized tomography (DCT).
  • To correlate DCT findings with clinical signs of vertebrobasilar circulatory disturbances.
  • To compare DCT results with those from carotid artery circulatory disturbances.

Main Methods:

  • Dynamic computerized tomography (DCT) was performed on 40 patients.
  • Patients included those with stabilized syndromes, transient disturbances, and carotid artery ischaemic episodes.

Main Results:

  • DCT abnormalities were detected in 90% of patients with stabilized syndromes.
  • DCT abnormalities were found in 40% of patients with transient ischaemia.
  • The study included comparative DCT examinations for carotid artery circulatory disturbances.

Conclusions:

  • Dynamic computerized tomography (DCT) can serve as an auxiliary diagnostic tool for vertebrobasilar circulatory failure.
  • Normal DCT results do not exclude the presence of arterial changes in the vertebrobasilar system.
