OBJECTIVE: To evaluate the correlation of collateral circulation with prognosis in patients with acute cerebral infarction.
METHODS: A total of 260 patients with acute ischemic stroke within 1 week of symptom onset underwent digital subtraction angiogram (DSA). The National Institutes of Health Stroke Scale (NIHSS) scores were obtained at admission. And the Modified Rankin scores (mRS) were assessed at a 3-month follow-up. The follow-up data were acquired through clinic visits or telephone interviews.
RESULTS: Among them, 86 were found to have intra- or extra-cranial culprit artery severe stenosis or occlusion. And 36 (75.00%) in 48 patients had collateral arterial circulation while 11 (28.64%) in 38 patients posterior circulation. There were statistical differences in the NIHSS scores at admission and favorite clinical outcome (mRS ≤ 2) at 3-month follow-up for patients with and without collateral circulation.
CONCLUSION: DSA is the golden standard for the assessment of collateral circulation in patients with severe cerebral artery stenosis or occlusion. The prognosis is better in stroke patients with collateral circulation.
