Study on the correlation between the number of intracranial artery stenosis and severity of cerebral infarction

ObjectiveTo investigate the correlation between the number of intracranial artery stenosis and severity of cerebral infarction.

MethodsThe clinical data of 100 patients with acute cerebral infarction were retrospectively analyzed.The clinical symptom severity and vascular stenosis of patients were evaluated using the national institutes of health stroke scale(NIHSS) and cervical MRA, respectively.The number of bilateral internal carotid artery and vertebral artery stenosis were counted, and the correlation between the number of intracranial artery stenosis and NIHSS score was analyzed.

ResultsThe age, number of intracranial artery stenosis and fasting blood glucose were the risk factors of the severity of ischemic stroke(P < 0.05 to P < 0.01).The difference of the NIHSS score in patients with different number of intracranial artery stenosis was statistically significant(P < 0.01), and which in patients with single branch stenosis was lower than that in patients with multiple branches stenosis(P < 0.01), and the differences of the NIHSS score between single and double branches, and between double and multiple branches were not statistically significant(P>0.05).

ConclusionsThe number of intracranial artery stenosis is significantly related to the severity of cerebral infarction, and the independent risk factor of the severity of cerebral infarction.
