Objective To analyze the risk factors for recurrence of intracranial aneurysms after interventional treatment. Methods Forty patients with intracranial aneurysms admitted to our hospital from June 2021 to June 2023 were selected as study subjects. All patients underwent interventional treatment and were followed up for one year after surgery. Arterial angiography was performed 6 months postoperatively and again one year later to check for recurrence. The patients were divided into a recurrence group （11 cases） and a non-recurrence group （29 cases） based on whether the aneurysm had recurred. The aneurysm location, aneurysm diameter, aneurysm neck classification, Raymond grading, smoking and alcohol consumption after treatment were compared between the two groups. Multivariate logistic regression analysis was used to identify the risk factors for recurrence of intracranial aneurysms after interventional treatment, and corresponding prevention strategies were formulated. Results There was no statistically significant difference in the location of aneurysms between the recurrence group and the non-recurrence group （P>0.05）. The recurrence group had higher incidence rates of aneurysms with a diameter of 5-6 mm, a wide neck type, and class Ⅱ-Ⅲ by Raymond grading, and smoking and alcohol consumption rates after treatment compared to the non-recurrence group （P<0.05）.The multivariate logistic regression analysis showed that aneurysm diameter, aneurysm neck classification, Raymond grading, smoking, and alcohol consumption were independent risk factors for recurrence of intracranial aneurysms after interventional treatment. Conclusion The risk factors for recurrence of intracranial aneurysms after interventional treatment include aneurysm diameter, aneurysm neck classification, Raymond grading, smoking, and alcohol consumption. It is recommended that patients with large aneurysm diameter, wide aneurysm neck classification, and high Raymond grading undergo regular postoperative follow-up and early intervention. In addition, it is recommended that patients avoid smoking and alcohol consumption after surgery to reduce the risk of disease recurrence.
