Pronóstico al año de la hemorragia subaracnoidea cortical no traumática: Serie prospectiva de 34 pacientes / One-year prognosis of non-traumatic cortical subarachnoid haemorrhage: A prospective series of 34 patients

Introducción: Las hemorragias subaracnoideas corticales (HSAc) tienen numerosas etiologías. No hay estudios prospectivos que indiquen su evolución a largo plazo. El objetivo de este trabajo es describir las características clínicas y etiológicas de los pacientes con HSAc y conocer su pronóstico.MétodosEstudio observacional, prospectivo y multicéntrico. Se recogieron variables clínicas y radiológicas, y se siguió la evolución al año, observando la mortalidad, dependencia, tasa de resangrado y aparición de demencia.ResultadosSe incluyeron 34 pacientes (edad media 68,3 años, rango 27-89). Los síntomas más frecuentes fueron el déficit neurológico focal, con frecuencia transitorio y de repetición, y la cefalea. El TAC fue patológico en 28 pacientes (85%). Se realizó RM cerebral en 30 pacientes (88%), con isquemia aguda en 10 (29%), sangrados antiguos en 7 (21%) y siderosis superficial en otros 2 (6%). Se encontró etiología en 26 pacientes (76,5%): angiopatía amiloide (n = 8), ictus isquémico (n = 5), vasculitis (n = 4), encefalopatía posterior reversible (n = 2), trombosis venosa (n = 2), síndrome de vasoconstricción cerebral reversible (n = 2), oclusión carotidea (n = 1), síndrome de Marfan (n = 1) y carcinomatosis meníngea (n = 1). Durante el seguimiento fallecieron 3 pacientes (en 2 de ellos relacionado con la causa de la HSAc). Tres pacientes desarrollaron una demencia, 3 presentaron un hematoma lobar y otro una nueva HSAc.ConclusionesEn nuestra serie las causas más frecuentes de HSAc fueron la angiopatía amiloide, el ictus isquémico y la vasculitis. La HSAc tiene peor pronóstico que otras HSA no aneurismáticas. Puede tener numerosas causas y su pronóstico depende de la etiología subyacente. En el anciano existe una frecuente asociación con hemorragia intracraneal y deterioro cognitivo. (AU)

Introduction: Cortical subarachnoid haemorrhage (cSAH) has multiple aetiologies. No prospective study has reported the long-term progression of the condition. The objective of this study is to describe the clinical and aetiological characteristics of patients with cSAH and to gain insight into prognosis.MethodsWe performed a prospective, observational, multi-centre study. Data on clinical and radiological variables were collected; during a one-year follow-up period, we recorded data on mortality, dependence, rebleeding, and the appearance of dementia.ResultsThe study included 34 patients (mean age, 68.3 years; range, 27-89). The most frequent symptoms were headache and focal neurological deficits, which were frequently transient and recurrent. CT scans returned pathological findings in 28 patients (85%). Brain MRI scans were performed in 30 patients (88%), revealing acute ischaemia in 10 (29%), old haemorrhage in 7 (21%), and superficial siderosis in 2 (6%). Aetiology was identified in 26 patients (76.5%): causes were cerebral amyloid angiopathy in 8, ischaemic stroke in 5, vasculitis in 4, reversible posterior encephalopathy in 2, venous thrombosis in 2, reversible cerebral vasoconstriction syndrome in 2, carotid occlusion in 1, Marfan syndrome in 1, and meningeal carcinomatosis in 1. Three patients died during follow-up (2 due to causes related to the cause of cSAH). Three patients developed dementia, 3 had lobar haemorrhages, and one had a second cSAH.ConclusionsThe most frequent causes of cSAH in our series were cerebral amyloid angiopathy, ischaemic stroke, and vasculitis. This type of haemorrhage has a worse prognosis than other non-aneurysmal cSAH. There are numerous possible causes, and prognosis depends on the aetiology. In elderly patients, intracranial haemorrhage is frequently associated with cognitive impairment. (AU)

Ictus isquémico y apnea del sueño. Relación entre trastornos respiratorios durante el sueño y estenosis carotídea / Ischemic stroke and sleep apnea. Relationship between sleep breathing disorders and carotid stenosis

Objetivo. Evaluar si existe alguna asociación entre el número de trastornos respiratorios durante el sueño (TRS) y la estenosis carotídea extracraneal (ECS) significativa en pacientes que han sufrido un ictus isquémico o ataque isquémico transitorio (AIT). Pacientes y métodos. A 68 pacientes (72,2 años; 68 % varones) supervivientes a los 2 meses de un ictus isquémico o AIT se les recogieron variables generales, antropométricas, caracteristicas y repercusión del ictus y clinica relacionada con el síndrome de apneas-hipopneas durante el sueño (SAHS). Se efectuó el estudio neurovascular mediante doppler continuo carotídeo y doppler transcraneal, realizando angiorresonancia y/o arteriografía cerebral ante sospecha de estenosis superiores al 50 %, así como una poligrafía respiratoria pasado el proceso agudo para valorar el número y tipo de TRS. Resultados. Quince pacientes (22,1 %) presentaron una ECS. El 80 % de estos pacientes tenían un índice de apneashipopneas (lAH) > 30. Los pacientes con ECS sufrían mayor somnolencia (p = 0,01), un IAH más elevado (36,2 frente a 21,9; P = 0,003) Y una mayor desaturación nocturna de oxígeno (p = 0,01). También fue significativa mente superior en este grupo la presencia de hipertensión arterial (HTA) (p = 0,003), diabetes mellitus (p = 0,01) e hipercolesterolemia (p = 0,02), aunque en el análisis de regresión logística tan sólo la presencia de HTA (odds ratio [OR]: 12,7) y de un IAH > 30 (OR: 13,6) presentaron un poder predictivo independiente de ECS. Conclusiones. La presencia de un elevado número de TRS presenta un valor predictivo de ECS independiente de la presencia de HTA. Los pacientes con ECS presentan más clínica relacionada con el SAHS previa al ictus, por lo que éste podría ser anterior al evento neurológico y funcionar como factor de riesgo para el mismo en este grupo de pacientes

Objetive. To investigate the possible relation between the number of sleep breathing disorders (SBD) and significant extracranial carotid stenosis (ECS) in patients suffering ischemic stroke or transient ischemic attack (TIA). Patients and methods. Sixty-eight patients (72.2 years; 68 OJo males) surviving two months after ischemic stroke or TIA were studied, with the collection of general and anthropometric variables, the characteristics and repercussions of stroke, and the clinical manifestations related to sleep apnea-hypopnea syndrome (SAHS). Neurovascular status was evaluated by carotid continuous doppler flowmetry and transcraneal doppler, with cerebral MR-angio and/or arteriography when suspecting stenosis > 50 %, and respiratory polygraphy after the acute phase to assess the number and type of SBD. Results. Fifteen patients (22.1 %) presented ECS. Of these, 80 % had an apnea-hypopnea index (AHI) > 30. The patients with ECS presented increased drowsiness (p = 0.01), greater AHI (36.2 vs 21.9; P = 0.003), and increased nocturnal oxygen desaturation (p = 0.01). Arterial hypertension (AHT) was also significantly more prevalent in this group of patients (p = 0.003), as was diabetes mellitus (p = 0.01) and hypercholesterolemia (p = 0.02) though logistic regression analysis only showed ART (odds ratio [OR]: 12,7) and AHI > 30 (OR: 13,6) to exhibit independent ECS predictive capacity. ConcIusions. The presence of numerous SBD is predictive of ECS, independently of the presence of ART. Patients with ECS have more SAHS related clinical mainfestations prior to stroke; as a result, SAHS could be anterior to the neurological event and act as a risk factor for the latter in this group
