ABSTRACT
Authors reported the anatomical and clinical results of the stent assisted coiling (SAC) of unruptured middle cerebral artery (MCA) aneurysms using Low-profile Visualized Intraluminal Support Junior (LVIS Jr.). Forty-seven MCA aneurysms in 46 patients were the subjects of this study. The mean aneurysm size, neck width were 4.5 ± 1.8 mm, 3.0 ± 1.0 mm, respectively. Immediate anatomical outcomes were class â
in 31 (65.0%), class â
¡ in 5 (10.6%) and class III in 11 (23.4%) patients according to Raymond-Roy classification. The latest anatomical outcomes were class â
in 33 (86.8%), class â
¡ in 2 (5.3%) and class III in 3 (7.9%) patients. The change of aneurysm obliteration status were unchanged in 27 (71.0%), improved in 9 (23.7%) and worsen in 2 (5.3%). There were no recurrence necessitating additional treatment. Two patients suffered from angiographically evident in-stent thrombosis, but their clinical outcomes remain good. The modified Rankin scale at discharge were 0 in 45 patients, 1 in 1 patient. No patient showed clinical worsening during the clinical follow-up period at outpatient clinic (mean, 27.4 months). SAC of unruptured MCA aneurysms using LVIS Jr. provide safe and durable effect with high complete obliteration rate recurrence rate.
