Abstract
Objective

To determine the safety and efficacy of angioplasty with a retrievable stent in treating vasospasm secondary to subarachnoid hemorrhage (SAH) due to an aneurysm.

Methods

We retrospectively analyzed prospectively collected data from consecutive patients undergoing endovascular angioplasty with a retrievable stent to treat vasospasm related to SAH due to an aneurysm in four neurointerventional radiology departments between January 2018 and July 2019. We included patients aged >18 years with vasospasm >50% of the internal carotid artery (ICA), anterior cerebral artery (ACA), and / or middle cerebral artery (MCA) secondary to SAH due to an aneurysm treated with endovascular angioplasty with a retrievable stent. The variables used to measure safety were complications of the procedure and clinical complications. The variables used to measure radiological efficacy were improvement in the degree of stenosis after endovascular treatment and improvement or normalization of cerebral circulation time CTT).

Results

We included 16 angioplasty procedures with retrievable stents in 13 patients, in which 33 arterial segments were treated (10 ICA, 15 MCA, and 8 ACA). We observed no complications of the procedure in any patients and no clinical complications in patients who were not intubated. All but one of the patients who had delayed CTT at the beginning of the procedure showed improvements in CTT. The mean improvement in the degree of stenosis was 18% ± 11.65% in the ICA, 30.67% ± 18.45% in the MCA, and 28.38% ± 15.49% in the ACA. No statistically significant associations were observed between endovascular treatment variables and the degree of improvement in stenosis.

Conclusion

Angioplasty with a retrievable stent is a safe and efficacious treatment for vasospasm secondary to SAH due to an aneurysm, improving CTT and stenosis.

Resumen
Objetivo

El objetivo es informar de nuestro estudio multicéntrico de seguridad y eficacia acerca de la angioplastia con stent recuperable en el vasoespasmo secundario a la hemorragia subaracnoidea por aneurisma (HSAa).

Métodos

Realizamos un análisis retrospectivo de una base de datos prospectiva de pacientes consecutivos sometidos a tratamiento endovascular mediante angioplastia con stent recuperable para el vasoespasmo relacionado con la HSAa en cuatro departamentos de neurorradiología intervencionista, entre enero de 2018 y julio de 2019. Incluimos a pacientes consecutivos mayores de 18 años con vasoespasmo mayor del 50% de la arteria carótida interna (ACI), la arteria cerebral anterior (ACA) y/o las arterias cerebrales medias (ACM) secundario a HSAa, tratado endovascularmente mediante angioplastia con stent recuperable. Las complicaciones del procedimiento y las complicaciones clínicas se registraron como variables de seguridad. Las variables de eficacia radiológica del procedimiento se definieron como la mejora en el porcentaje de estenosis después del tratamiento endovascular y la mejora o normalización del tiempo de circulación cerebral (TCC).

Resultados

Incluimos 16 procedimientos de angioplastia con stent recuperable en 13 pacientes, con 33 segmentos arteriales tratados (10 ACI, 15 ACM y 8 ACA). No encontramos complicaciones de procedimiento en ningún paciente, ni complicaciones clínicas en pacientes no intubados. Todos los pacientes con TCC retrasado al principio del procedimiento, excepto uno, mostraron una mejora en el TCC. La mejora en el porcentaje de estenosis en la ACI fue de 18 ± 11,65 (media ± DE), 30,67 ± 18,45 en la ACM y 28,38 ± 15,49 en la ACA. No encontramos ninguna asociación estadísticamente significativa entre las variables de tratamiento endovascular y la mejora en el porcentaje de estenosis.

Conclusión

La angioplastia con stent recuperable como tratamiento del vasoespasmo secundario a la HSAa es un procedimiento seguro y eficaz que mejora el TCC y la estenosis del vaso después del tratamiento.
