RESUMO
Objective To summarize operation experiences in applying microcoils embolization for the treatment of intracranial wide-necked aneurysms using the low-profile visualized intraluminal stent support (LVIS) in elderly patients.Methods We reviewed data of 47 elderly patients (48 aneurysms) with intracranial wide-necked aneurysms treated with LVIS stent-assisted microcoils embolization.Results Forty-seven aneurysms were embolized successfully,one stent was withdrawn because its midpiece failed to stretch.Instant Raymond classifications evaluation after the surgery showed Grade Ⅰ in 52.1％ (25/48 aneurysms),Grade Ⅱ in 37.5％ (18/48 aneurysms),and Grade Ⅲ in 8.3 ％ (4/48 aneurysms).Besides,the effective rate of aneurysms embolization was 91.5 ％.During 3 to 12-month follow-up with digital subtraction angiography (DSA) in 36 patients (36 aneurysms),mRS was scored 0 (best effectiveness) in 28 cases,scored 1 in 4 cases,scored 2 in 3 cases,and scored 3 in 1 case,and the total favorable rate was 97％.Conclusions LVIS stent-assisted microcoils embolization for the treatment of intracranial wide-necked aneurysms in elderly patients may avoid or reduce the incidence of complication.
