Abstract:
Objective:To investigate the related factors of cerebral collateral circulation in patients with acute cerebral infarction (ACI).Methods:A retrospective study was conducted on 4 483 inpatients with ACI admitted to the Renqiu Kangji Xintu Hospital from January 2014 to November 2018 were selected as the research subjects. According to transcranial Doppler (TCD) and CT angiography(CTA) examination results, they were divided into the group with collateral circulation (154 cases) and the group without collateral circulation (4 329 cases) according to the presence of collateral circulation. The related factors affecting the formation of cerebral collateral circulation in the two groups were statistically analyzed. According to the Modified Rankin Scale (mRS) score, 0 - 1 score was defined as good discharge outcome, and mRS ≥ 3 scores was defined as bad discharge outcome. The relationship between collateral circulation opening and poor discharge outcome was analyzed.Results:Compared with the group without collateral circulation, age: 67.00 (61.00, 73.00) years vs. 65.00 (57.00, 72.00) years, history of stroke: 52.59% (81/154) vs. 32.08% (1 389/4 329), carotid artery stenosis: 85.71% (132/154) vs. 20.23%(876/4 329), homocysteine (Hcy): 16.85 (13.00, 28.03) μmol/L vs. 15.00 (11.00, 21.00) μmol/L, significantly promoted the formation of collateral circulation, and the differences were statistically significant ( P<0.05). After adjusting for confounding factors, age ( OR = 0.97, 95% CI 0.95 - 0.99), stroke history ( OR = 1.60, 95% CI 1.11 - 2.32), carotid artery stenosis ( OR = 23.63, 95% CI 14.64 -38.11) and Hcy ( OR = 1.01, 95% CI 1.00 -1.02) were independent factors promoting the formation of cerebral collateral circulation in ACI patients ( P<0.05), carotid artery stenosis was a significant promoting factor, OR value was 23.63. Receiver operating characteristic (ROC) curve analysis showed that the model predicted the area under the curve value of cerebral collateral circulation opening reached 0.869. Among 4 483 ACI patients, 798 cases (17.80%) had poor discharge outcome, including 18 cases (11.68%) with collateral circulation and 780 cases (18.01%) without collateral circulation, suggesting that the incidence of adverse discharge outcome was lower in the group with collateral circulation ( P<0.05), OR = 0.60, 95% CI 0.36 - 0.99, suggesting that the formation of cerebral collateral circulation was a factor promoting the good prognosis of ACI patients. Conclusions:Age, history of stroke, carotid artery stenosis and Hcy are correlated with the formation of cerebral collateral circulation in ACI patients. Existing model can effectively predict the formation of cerebral collateral circulation in ACI patients, and the formation of cerebral collateral circulation is closely related to the discharge outcome of ACI patients.
