Abstract:
Objective:To explore the risk factors for misdiagnosis of ruptured intracranial aneurysm.Methods:A total of 606 patients with ruptured intracranial aneurysms, admitted to our hospital from October 2014 to October 2020, were enrolled in our study; these patients were divided into two groups according to whether they were initially misdiagnosed: misdiagnosis group ( n=35) and non-misdiagnosis group ( n=571). The general clinical data of patients from the two groups were compared; multivariate Logistic regression was used to identify the independent influencing factors for misdiagnosis. Receiver operating characteristic (ROC) curve was drawn according to the regression model to evaluate the predictive value of different factors for misdiagnosis. The re-rupture of aneurysms and different prognoses were compared between the two groups. Results:There were significant differences in Fisher grading, primarily visited departments, aneurysm diameters, hospital levels, and propaganda and education situation of the first visited doctors between the 2 groups ( P<0.05). Multivariate Logistic regression analysis showed that the independent factors for misdiagnosis of ruptured intracranial aneurysms were as follows: modified Fisher grading 0-II ( OR=12.284, 95%CI: 5.397-27.958, P=0.000); aneurysm diameter ≥10 mm ( OR=2.871, 95%CI: 1.276-6.456, P=0.011), not neurology or neurosurgery as primarily visited departments ( OR=9.279, 95%CI: 4.019-21.420, P=0.001), and first visited doctor not receiving propaganda and education ( OR=2.907, 95%CI: 1.258-6.721, P=0.013); area under the ROC curve of not neurology or neurosurgery as primarily visited departments and modified Fisher grading 0-II were 0.747 and 0.754, which had good predictive value in the misdiagnosis of ruptured intracranial aneurysm. Re-ruptured aneurysms occurred in 37.1% patients from the misdiagnosis group and 5.3% patients from the non-misdiagnosis group, with significant difference ( P<0.05); and the proportion of patients with poor prognosis at discharge (modified Rankin scale scores>2) was 42.9% in the misdiagnosis group and 22.6% in the non-misdiagnosis group, with significant difference ( P<0.05). Conclusion:Patients with modified Fisher grading 0-II, without neurology or neurosurgery as primarily visited departments and with aneurysm≥ 10 mm, and patients whose first visited doctor not receiving professional education of spontaneous subarachnoid hemorrhage have high risks of misdiagnosis of ruptured intracranial aneurysm; strengthening the professional education of spontaneous subarachnoid hemorrhage for doctors from non-neurology or neurosurgery departments of hospital at different levels may reduce the misdiagnosis rate.
