Angiographical findings and risk factors in cerebral ischaemia. A retrospective study
European Neurology
|January 1, 1980
Insights
Angiograms revealed intracranial or extracranial lesions in most patients with reversible ischemic attacks (RIA) or stroke. More extensive lesions correlated with increased risk factors, highlighting the importance of examining intracranial vessels.
Area of Science:
- Neurology
- Radiology
- Vascular Medicine
Background:
- Cerebral ischemia, including stroke and reversible ischemic attacks (RIA), poses a significant health burden.
- Identifying the source of ischemia is crucial for effective treatment and prevention.
- Angiography is a key diagnostic tool for evaluating cerebrovascular disease.
Purpose of the Study:
- To investigate the prevalence and extent of intracranial and extracranial lesions in patients presenting with RIA or stroke.
- To determine the correlation between the extent of angiographic findings and the presence of risk factors.
- To underscore the diagnostic value of intracranial angiography in managing cerebral ischemia.
Main Methods:
- Retrospective review of angiograms from 100 patients diagnosed with RIA or stroke.
- Categorization of lesions as intracranial, extracranial, or normal.
- Analysis of the relationship between lesion extent and patient risk factors.
Main Results:
- Intracranial lesions were identified in 67% of patients.
- Extracranial lesions were detected in 64% of patients.
- Normal angiograms were observed in 13% of cases, with a positive correlation between lesion extent and the number of risk factors.
Conclusions:
- Angiographic examination of intracranial vessels is essential for patients with cerebral ischemia.
- The findings support the routine use of angiography to identify causative lesions in stroke and RIA.
- Extensive lesions on angiography indicate a higher risk profile in patients with ischemic events.
Abstract:
Reviewing the angiograms of 100 patients with RIA or stroke we found intracranial lesions in 67%, extracranial lesions in 64%, and normal angiograms in 13% of the cases. Risk factors occurred more often as the angiographic lesions were more extensive. These findings confirm the importance of angiographic examination of the intracranial vessels in patients with cerebral ischaemia.
