Resumen

Introducción: los aneurismas intracraneales son una dilatación local y permanente de una arteria.
Objetivo: describir las características clínicas, imagenológicas y la efectividad del tratamiento endovascular en términos de independencia y mortalidad en pacientes con aneurismas disecantes de circulación cerebral posterior en Cartagena.
Métodos: se realizó un estudio observacional descriptivo en pacientes de 18 años o mayores, con diagnósticos de aneurismas disecantes y de circulación cerebral posterior que recibieron tratamiento endovascular (TEV) en el período comprendido entre enero de 2007 y diciembre de 2014 en el centro Neurodinamia. Se midieron las variables relacionadas con antecedentes patológicos personales, diagnóstico y características del aneurisma, dispositivos utilizados para el tratamiento, tiempos de seguimiento clínico e imagenológico y complicaciones. Se realizó análisis estadístico descriptivo según la naturaleza de las variables.
Resultados: se analizaron 19 pacientes con tratamientos endovasculares. La mediana de edad fue de 55 años. La hemorragia subaracnoidea fue la presentación clínica más frecuente, el 89.5% de ellos fueron diagnosticados con TAC. La localización en la PICA y arteria vertebral fueron de 36.8% y 31.6%, respectivamente. El tipo de dispositivos usados fueron los coils en 36.8%, seguido de coils y stent con 31.6% y onyx en 21.0%. Al finalizar la TEV se clasificó como resultado favorable en 18 pacientes (94.7%), se presentó una muerte intrahospitalaria (5.3%). La escala Rankin al seguimiento mostró mejoría en el 84.2% (16 pacientes).

Conclusiones: el TEV de los aneurismas disecantes de circulación cerebral posterior por oclusión del aneurisma muestra una alta frecuencia de éxito técnico 94.7%, con un 84.2% de los pacientes con resultado favorable a los 30 días después del tratamiento. Rev.cienc.biomed. 2015;6(2):298-308
