ABSTRACT

Purpose:

The performance of the Low-Profile Visualized Intraluminal Support (LVIS) stentdeployed following balloon angioplasty is unknown in treating intracranial atherosclerotic stenosis, and this study was to investigate the safety and efficacy of the LVIS stent in treatingintracranial atherosclerotic stenosis in the middle cerebral artery M1 segment.

Methods:

Thirty-five patients were enrolled with 35 atherosclerotic stenoses at the M1 segment. The stenosis was about 75% in 16 patients, 80% in 15, and 90% in the rest four. The LVISstent was used to treat these patients.

Results:

The success rate of stenting was 97.1%. The stenting procedure was failed in onepatient because of intraprocedural dissection of the stenotic (75%) segment, resulting in a 30-day periprocedural complication rate of 2.9% (1/35). Before stenting, the stenosis rate ranged75%—90% (mean 78.9% ± 4.7%), and after stenting, the diameter of the stented segment wassignificantly (P < 0.0001) increased to 1.5—3.4 mm (mean 2.1 ± 0.32 mm) ranging 68.2%—100%(mean 94.0% ± 5.8%) of the normal arterial diameter, with the residual stenosis ranging 0—31.8%(median 4.8%, IQR 2.4%—7.3%). Follow-up was performed at 6—20 months (mean 8.5) afterstenting. One patient (2.9%) had occlusion of the stented M1 segment with no symptoms, andtwo patients (5.7%) had slight asymptomatic instent stenosis (40%) at the M1 segment, with theinstent restenosis and occlusion rate of 8.6% (3/35).

Conclusion:

The braided LVIS stent can be safely applied for treatment of intracranialatherosclerotic stenosis in the middle cerebral artery with good safety and efficacy immediatelyafter stenting and at follow-up.(AU)
RESUMEN

Objetivo:

Nos propusimos analizar la seguridad y efectividad de la colocación de un stentlow-profile visualized intraluminal support (LVIS TM ) tras angioplastia con balón en pacientescon estenosis ateroscleróticas intracraneales en el segmento M1 de la arteria cerebral media(ACM).

Métodos:

Incluimos 35 pacientes con estenosis ateroscleróticas en el segmento M1 de la ACM;la estenosis era del 75% en 16 pacientes, del 80% en 15 y del 90% en los 4 restantes. En todoslos casos el tratamiento se basó en la colocación de un stent LVIS TM .

Resultados:

El stent se implantó con éxito en el 97,1% de los casos; en un paciente, el procedimiento no se pudo llevar a cabo a causa de una disección del segmento estenótico (estenosisdel 75%) durante la operación, lo que supone una tasa de complicaciones perioperatorias a los30 días del 2,9%. Antes de la colocación del stent, el grado de estenosis oscilaba entre el 75 yel 90% (media [DS] 78,9% [4,7%]). Tras el procedimiento, el diámetro del segmento en el quese había colocado el stent aumentó de forma significativa (P < 0,0001) hasta los 1,5-3,4 mm(media 2,1 mm [0,32]), logrando un 68,2-100% (media 94,0% [5,8%]) del diámetro normal dela arteria, y una estenosis residual del 0 al 31,8% (mediana 4,8%; p25-p75, 2,4-7,3%). Se realizóun seguimiento de entre 6 y 20 meses (media 8,5) tras el procedimiento. Un paciente (2,9%)presentó una oclusión asintomática del segmento M1 intervenido, y 2 pacientes (5,7%) presentaron estenosis intrastent asintomáticas leves (40%) en M1, por lo que la tasa de reestenosisintrastent y oclusión fue del 8,6%.

Conclusión:

El stent LVIS TM es un tratamiento seguro y efectivo para las estenosis ateroscleróticas intracraneales en la ACM.(AU)
