Abstract: Objective To explore the efficacy of ultra - early stent - assisted coil (SAC) in the treatment of intracranial rupture of wide - necked aneurysms. Methods The angiographic and clinical data of 24 patients (including 8 male, 16 female, age ranged from 29 to 86 years, with a median age 59) with acutely ruptured wide-necked intracranial aneurysms treated with SAC were retrospectively analyzed. The postoperative complications and clinical results were observed. The postoperative embolization was assessed according to the Raymond grading standard. The assessment of the follow-up results from 6 to 12 months after procedure was observed according to the modified Rankin Scale (mRS) score. Results Procedurerelated complications occurred in 3 patients (12.5% ). All of them were hemorrhagic events, of which 2 cases died. Perioperative death was found in 3 cases. Of the 19 surviving patients, 17 showed good recovery (mRS 0-2). After 6 to 12 months of DSA, no recurrence of aneurysm was found in 10 follow-up patients. Conclusion Ultra-early stent-assisted coil treatment for intracranial wide- neck rupture aneurysm can improve the success rate of embolization and reduce the recurrence.
