Two thirds of patients with this condition are male. The mean age at which cerebellar infarcts appear is approximately 65 years. 2,3Īt present, thanks to MRI brain scans, we can identify the affected territory more accurately, and detect other associated lesions. 1–3 Their clinical manifestations are very diverse and often unspecific, meaning that this entity is often mistaken for other more benign conditions. Sin embargo, cabe destacar que los infartos de PICA son los más prevalentes, su etiología suele ser aterotrombótica y son los más asociados a complicaciones graves, que ocurren durante la primera semana del ictus.Ĭerebellar infarcts account for between 1.5% and 3% of all ischaemic strokes. Al alta, la dependencia funcional (Rankin ≥ 3) era mayor si la afectación territorial era múltiple (64% vs 31-36% p = 0,05). Se asoció hidrocefalia en 15 pacientes (12,1%, 12 de ellos PICA p = 0,02), apareciendo de media a los 2,9 ± 1,5 días del inicio del ictus. Se produjo transformación hemorrágica en 29 pacientes (23,4%), sobretodo en la afectación de múltiples territorios y en PICA. La etiología aterotrombótica fue más prevalente en PICA (p = 0,02) y la cardioembólica en la afectación de múltiples territorios (p = 0,04), siendo similares en ACS y AICA. Se afectaron territorios supra-infratentoriales en el 13,7% y dos/tres territorios cerebelosos en el 8,9%. El territorio más afectado fue la arteria cerebelosa posteroinferior (PICA) en el 49,2%, seguido de la arteria cerebelosa superior (ACS) en el 17,7% y cerebelosa anteroinferior (AICA) en el 10,5%. La edad media de nuestra serie es de 65,2 años, con predominio masculino (68,5%). Se han recogido datos de 124 pacientes ingresados en nuestro servicio durante un periodo de 5 años, con diagnóstico radiológico de IC, con y sin afectación de otras regiones cerebrales. Nuestro objetivo ha sido estudiar las características de los pacientes con IC, así como su evolución, en función del territorio afectado. Los infartos cerebelosos (IC) son infrecuentes pero pueden presentar complicaciones graves.

Moreover, it is the territory most frequently associated with severe complications, which take place during the first week of the stroke.

Nevertheless, it is noteworthy that PICA infarction is the most frequent type and its aetiology is usually atherothrombotic. At discharge, the degree of disability was worse if more than one arterial territory was involved (Rankin ≥ 3, 64% versus 31–36% P =. There was hydrocephalus in 15 patients (12.1%, 12 of them PICA P =. There was haemorrhagic transformation in 29 patients (23.4%), particularly in the PICA and when other territories were involved. No particular aetiology could be found in SCA and AICA. On the other hand, cardio-embolism was the main origin in cases with more than one affected territory ( P =. The main aetiology in PICA was atherothrombosis ( P =. There was simultaneous supratentorial involvement in 13.7%, and two or three cerebellar arteries involved in 8.9%. The posterior inferior cerebellar artery (PICA) was the most commonly affected territory at 49.2%, followed by superior cerebellar artery (SCA) at 17.7%, and anterior inferior cerebellar artery (AICA) at 10.5%. The mean age in our series was 65.2 years, with most being male (68.5%). Patients and methodsĭata were collected from 124 patients admitted to our department during a five-year period, with a radiological diagnosis of CI, and with or without involvement of other brain territories. The aim of our study was to determine the characteristics of patients with CI, as well as their outcomes as regards the territories affected. Cerebellar infarction (CI) is uncommon, but may result in severe complications.
