[Electroencephalographic studies in thrombosis of extracranial arteries]
Insights
Electroencephalography (EEG) changes correlate with extracranial artery disease. Restoring arterial blood flow through surgery often improves EEG results, indicating better cerebral circulation.
Area of Science:
- Neurology
- Vascular Surgery
Background:
- Extracranial arterial changes can impact cerebral circulation.
- Electroencephalography (EEG) is used to assess brain activity.
Observation:
- EEG investigations were performed on 60 patients with confirmed extracranial artery disease.
- 15 patients underwent surgical intervention to restore arterial patency.
- EEG abnormalities were analyzed in relation to specific artery involvement (internal carotid, aortic arch) and thrombosis extent.
Findings:
- Internal carotid artery disease, due to its proximity to the brain, can lead to more significant cerebral ischemia and pronounced EEG changes.
- Post-surgical comparison of EEG records in treated patients showed improvement in most cases.
Implications:
- Restoration of arterial patency favorably impacts cerebral circulation, as evidenced by EEG improvements.
- EEG can be a valuable tool for monitoring the effects of interventions for extracranial arterial disease.
Abstract:
In 60 patients with arteriographically confirmed changes in extracranial arteries EEG investigations were carried out. In 15 of them surgical interventions were performed for restoring the patency of the involved artery. EEG curves were studied for finding abnormalities in cases of changes in definite groups of arteries (internal carotid, arteries of the aortic arch), and correlations were sought for between the extent of thrombosis and EEG curves. In the patients treated surgically EEG curves were compared before and after the operation. The author concludes that changes limited to the internal carotid artery lying which is situated nearer to the head can produce larger foci of cerebral ischaemia and greater intensity of EEG changes. In the surgically treated patients EEG records were improved after the operation in most cases, which shows that restoration of arterial patency exerts a favourable effect on the cerebral circulation evidenced in EEG improvement.
