单纯放置LVIS支架治疗颅内动脉瘤的初步经验OACSTPCD

Objective To investigate the efficacy and safety of LVIS stent alone in the treatment of intracranial aneurysms(IAs).Methods The clinical data of 45 patients treated by LVIS stent alone were retrospectively collected.The characteristics of IAs and the imaging follow-up results were analyzed.Results A total of 48 IAs were treated in 45 patients with LVIS stents alone.All the patients received cerebral angiography recheck 4-24 months after operation,the median recheck time was 7 months.Raymond classified 31 IAs as grade Ⅰ,4 as grade Ⅱ,and 13 as grade Ⅲ,the overall cure rate was 64.58%.Thirty IAs were treated with single LVIS stent,the cure rate was 56.67%,and 18 IAs were treated with double LVIS stents,the cure rate was 77.78%.All patients received outpatient or telephone follow-up at 6 months after discharge,and no serious ischemia or bleeding events occurred.The modified Rankin scale(mRS)score was 0-2.Conclusion LVIS stent placement alone is safe and feasible for the treatment of IA,but the cure rate is lower than that of LVIS stent assisted coil embolization,so it should not be the first choice for the treatment of IA.However,for patients who cannot have a coil inserted intraoperatively,or who do not receive flow guide device or craniotomy before surgery,double LVIS stents can be an alternative or intraoperative remedy.
