All participants underwent preoperative preparation, including clinical examination and angiographic assessment of the target aneurysm. Before randomization, the parameters collected included age, sex, and rupture status. In addition, other baseline data were obtained on aneurysm size and location. After surgery, the following data were collected on the coils, assist devices, complications, and angiographic images. At 1-month post-implantation, investigators followed up with each participant by telephone. DSA was recommended at the 6-month follow-up, while MRA was suggested at the 12-month follow-up. In addition, complications and additional interventions for the target aneurysm at any time were documented.Digital copies of imaging data before treatment, immediately after treatment, at the 6-month follow-up, and the clinical research organization collected during the 12-month follow-up. An independent core laboratory and Clinical Events Committee (CEC), comprised of three members qualified in neuroimaging or equivalent qualifications, located at the Sixth People’s Hospital, Shanghai, reviewed all the imaging and endpoint events. The degree of aneurysm occlusion was assessed according to the 3-class Raymond scale (complete occlusion, neck remnant, and residual aneurysm). The modified Rankin Scale (mRS) score was also obtained during the follow-up.
