Objective To analyze the safety of stent assisted endovascular embolization for ruptured and unruptured small intracranial wide necked aneurysms and its clinical effect.
Methods Clinical data of 30 patients with small intracranial wide neck aneurysm was retrospectively included, and they were divided into rupture group (11 cases) and unrupture group (19 cases). All patients were treated with stent-assisted endovascular embolization. The incidence of surgical complications was analyzed, the efficacy of operation was evaluated by Raymond grading, and the prognosis was evaluated by modified Rankin scale (mRS).
Results The smoking rate in the ruptured group was significantly higher than that in unruptured group (P < 0.05). The immediate postoperative embolization grading of different stents (LIVS, Enterprise and Solitaire-AB) showed that LIVS stent assisted embolization had the best effect, while Solitaire-AB stent assisted embolization had the worst effect (P < 0.05). Compared with the unruptured group, the rate of cerebral vasospasm in the ruptured group was significantly higher, the length of hospitalization was significantly longer, and the rate of poor prognosis at discharge was significantly higher (P < 0.05). Ten patients underwent imaging follow-up, and all of them were Raymond-Ⅰ grade.
Conclusion Stent-assisted embolization for small intracranial wide-necked aneurysms is safe and effective, especially in unruptured patients. The therapy has good immediate embolization effect, fewer surgical complications and good follow-up results, and LIVS stents may have more advantages.
