Abstract：Objective To explore the difference between the Unruptured Intracranial Aneurysms Treatment Score(UIATS)and clinical treatment decision-making scheme in the treatment outcome of unruptured intracranial aneurysms(UIA),and to provide reference for clinical diagnosis and treatment.Methods The clinical data of 92 patients with UIA(a total of 108 intracranial aneurysms)were retrospectively analyzed,and all patients were registered with UIATS scores and clinical decision-making plans,and follow-up was carried out through visits and telephone consultation one year after the diagnosis of UIA.The differences between the two regimens in the complications in the perioperative period and the increase in aneurysm diameter during the follow-up period were analyzed.Results The median age of the 92 patients with UIA was 60.85 years,including 24 males(26.1%)and 68 females(69.6%).The aneurysm was located in the internal carotid artery segment in 46 cases(42.6%),the middle cerebral artery in 8 cases(7.4%),the anterior and posterior communicating arteries in 36 cases(33.3%),the vertebral artery and basilar artery in 12 cases(11.1%),and the basilar artery apex in 6 cases(5.6%).Among them,there were 80 small aneurysms(80/108,74.1%),with an average diameter of<6.9 mm.The surgical intervention was recommended for 87 patients(85%)and follow-up observation in 21(15%)by UIATS.Sixty-two patients(57.4%)were treated with surgical intervention and 46(42.6%)were followed up and observed.There was no statistically significant difference between the UIATS and the clinical protocol in terms of perioperative complications and increased diameter of aneurysm during the follow-up period.The Kendall correlation test between UIATS and clinical decision-making showed a 95%confidence interval(CI):0.570(0.479,0.650),P<0.001.There was no difference in the efficacy of UIATS and clinical regimens in aneurysm enlargement during the follow-up period of UIA(P=0.755).Conclusions There is no significant difference between the UIATS score diagnosis and treatment plan and the actual clinical decision-making plan for the treatment of unruptured aneurysms,and there is no increase in adverse events such as perioperative complications and increased diameter of aneurysms during the follow-up period.The UIATS can be used as a reference for guiding treatment plans in clinical work.
