Abstract
Objectives

We present the short- and long-term results of a series of patients with symptomatic intracranial arterial stenoses treated with angioplasty and stenting.

Materials and methods

We reviewed patients with symptomatic intracranial stenoses greater than 50% who were treated with angioplasty, stenting, or both. We recorded demographic data and risk factors (hypertension, diabetes, dyslipemia, ischemic heart disease). We classified all lesions treated according to their location, degree of stenosis, and length. The degree of stenosis was classified as moderate (50–70%) or severe (>70%). In the follow-up, we assessed cerebrovascular accidents, episodes of ischemic heart disease, and deaths in the first 30 days and in later follow-up.

Results

Between 2006 and 2010, we treated 26 patients (21 men and 5 women; age range, 44–79 years; mean age, 63 years) with 29 intracranial lesions. The endovascular procedure (angioplasty+stenting) was successfully performed in 23 cases (92.0%). In the first 30 days after the procedure, 3 (11.5%) patients had adverse effects of vascular origin: 1 stroke, 1 hemorrhage, and 1 death due to thrombosis of the stent. Long-term follow-up (5–46 months) in the 25 patients who survived more than 30 days detected no recurrence of symptoms.

Conclusion

Endovascular treatment of intracranial stenosis is technically feasible. Short-term complications are highly prevalent. No recurrence of symptoms was detected during long-term follow-up.

Resumen
Objetivos

Presentamos los resultados a corto y largo plazo de una serie de pacientes con estenosis arteriales intracraneales (EAIC) sintomáticas tratados en nuestro centro mediante angioplastia y endoprótesis.

Material y métodos

Revisión de pacientes con estenosis intracraneales>50% sintomáticas tratados en nuestro centro mediante angioplastia y/o colocación de endoprótesis. Se recogieron los datos demográficos y los factores de riesgo vascular (hipertensión, diabetes, dislipemia, cardiopatía isquémica). Todas las lesiones tratadas se caracterizaron por su localización, grado y longitud de la estenosis. El grado de estenosis se calificó como moderado (50–70%) o grave (>70%). En el seguimiento se evaluaron los accidentes cerebrovasculares, episodios de cardiopatía isquémica o fallecimientos ocurridos durante los 30 primeros días y en el seguimiento posterior.

Resultados

Entre 2006 y 2010 se trataron 26 pacientes (21 varones y 5 mujeres) con edades comprendidas entre 44 y 79 años (media: 63 años), con 29 lesiones intracraneales. El procedimiento endovascular se realizó con éxito (angioplastia+endoprótesis) en 23 casos (92.0%). En los 30 primeros días postintervención se produjeron tres (11,5%) efectos adversos de origen vascular: un ictus, una hemorragia y un fallecimiento por trombosis de la endoprótesis. El seguimiento a largo plazo se ha realizado sobre 25 pacientes (5–46 meses). No se han detectado recurrencias de la sintomatología.

Conclusión

El tratamiento endovascular de las EAIC es técnicamente factible. Las complicaciones del procedimiento a corto plazo tienen una prevalencia alta. No se ha detectado recurrencia de la sintomatología a largo plazo.
