MRA evaluation of cerebrovascular stenosis and its association with acute stroke in Indian patients
International Journal of Medical Research and Review
The detection of intracranial atherosclerotic disease has been elusive, possibly because of the dearth of non-invasive methods for diagnosing the condition. Material and Methods: In this study, we used time-of-flight MRA (TOF-MRA) to identify the presence, nature, and number of stenosis in the intra and extracranial arteries and anterior and posterior circulation systems in 60 Indian patients. Results: It was found that there is a strong association between the presence of stenosis and
... enosis and hyperlipidemia and hypertension. Intracranial stenosis was more prevalent in the > 60 years age group, and it maximally affected the M1 segment of the middle cerebral artery. Comparatively, significant stenosis and total occlusion were predominant in the intracranial system; single stenosis was associated with the intracranial arteries, whereas multiple stenoses were observed in the extracranial system. Conclusion: Hemiparesis was the most common symptom of the patients. Thus, TOF-MRA can be used successfully to evaluate the occurrence, prognosis, and treatment options for cerebrovascular stenotic diseases.
