Abstract
We aimed to characterize the clinical features,etiology and prognosis in lobar hemorrhages (LH).Descriptive study of 97 patients with LH included in the Sagrat Cor Hospital of Barcelona Stroke Registry over a 12 year period. The vascular risk factors and clinical profiles in a LH group and a subcortical hemorrhage group (n = 92) were compared.LH accounted for 3.9% of all acute strokes (n = 2,500) and 35.9% of all intracerebral hemorrhages. The parietal lobe was the most frequent cerebral topography (45.4%). LH were caused by arterial hypertension in 41% of patients, vascular malformations in 8.5%, bleeding diathesis in 5.5% and anticoagulation in 3%. The overall in-hospital mortality rate was 26.8%. Early seizures (odds ratio [OR] = 5.41; confidence interval [CI] 95%, 1.06-27.69), headache (OR = 2.19; CI 95%, 1.13-4.26), female sex (OR = 1.97; CI 95%, 1.04-3.75), sensory deficit (OR = 0.41; CI 95%, 0.22-0.77) and hypertension (OR = 0.34; CI 95%, 0.18-0.65) were independent predictors of LH.One in every 3 intracerebral hemorrhages is a LH. Different potentially modifiable vascular risk factors and clinical profiles were identified in LH versus subcortical hemorrhages.
