Abstract:
Objective To investigate the risk factors for unruptured intracranial aneurysms (UIA) in patients with acute cerebral infarction and whether the UIA affect early prognosis in patients with acute cerebral infarction.Methods Inpatients with acute cerebral infarction diagnosed at the Affiliated Hospital of Yangzhou University from January 2009 to August 2017 were retrospectively collected.Diagnosis of acute cerebral infarction and UIA was established by emergency magnetic resonance imaging and three dimensional time of flight magnetic resonance angiography screening.All patients with acute cerebral infarction were divided into the group with no intracranial aneurysm (A) and the group with UIA (B).Baseline materials such as demographics and cerebrovascular risk factors were used to analyze the comorbidity and risk factors of acute cerebral infarction and UIA.According to the modified Rankin scale (mRS) scores after 90 days,the patients were divided into a good prognosis group (mRS score ≤2) and a poor prognosis group (mRS score ≥3).The influence of the location,size,number of UIA and different treatments in the acute phase on the early prognosis of the two comorbidities was analyzed,and the relevant risk factors affecting prognosis were screened out.Results Of the 3 917 patients with acute cerebral infarction,3 641 patients met the inclusion criteria,and 237 patients (6.51％) had UIA.The proportion of age,women,smoking and hypertension in group B was significantly higher than that in group A.Multivariate regression analysis showed that women (odds ratio (OR)=1.691,95％ confidence interval (CI) 1.249-2.290,P=0.001),age (OR=1.023,95％ CI 1.010-1.036,P=0.000),smoking (OR=1.942,95％ CI 1.413-2.670,P=0.000),hypertension (OR=1.539,95％ CI 1.025-2.309,P=0.037) were significandy correlated with acute cerebral infarction complicated with UIA.There were 2 346 cases (64.43％) in the good prognosis group and 1 295 cases (35.57％) in the poor prognosis group after 90 days of onset.No statistically significant difference was found in the presence of UIA between the two groups (x2=0.002,P=0.967).There was no significant correlation between location,size and number of treatments,treatment patterns,the Trial of Org 10172 in Acute Stroke Treatment classification and patient outcome.Further Logistic regression analysis showed age (OR=1.009,95％CI 1.003-1.016,P=0.003),diabetes (OR=1.235,95％ CI 1.076-1.418,P=0.003),history of previous stroke (OR=1.544,95％ CI 1.324-1.801,P=0.000) and National Institutes of Healthy Stroke Scale (NIHSS) score at admission (OR=1.037,95％ CI 1.020-1.054,P=0.000) were significantly associated with poor outcomes in patients with acute cerebral infarction.Conclusions Female,age,smoking and hypertension were found to be risk factors for comorbidity of acute cerebral infarction and UIA.The location,size,and different treatments of UIA were not found to have a significant effect on early prognosis in patients with acute cerebral infarction;age,diabetes,previous stroke history,and baseline NIHSS score were high risk factors affecting early prognosis in patients with acute cerebral infarction with or without UIA.
