Hemorrhagic lacunar stroke.
A total of 17 patients with lacunar syndromes due to intracerebral hemorrhage or hemorrhagic lacunar stroke (pure motor hemiparesis 9, sensorimotor stroke 5, pure sensory stroke 3) are reported. Data from these patients were obtained from consecutive stroke patients included in the prospective Hospital Sagrat Cor-Aliança Stroke Registry. Hemorrhagic lacunar stroke accounted for 3.8% of all cases of lacunar syndrome (n = 439) and 7.4% of all cases of intracerebral hemorrhage (n = 229) entered in the database. Demographic, anamnestic, clinical and neuroimaging variables in patients with hemorrhagic lacunar stroke, non-lacunar intracerebral hemorrhage and non-hemorrhagic lacunar stroke were compared. Predictors of hemorrhagic lacunar stroke were assessed by logistic regression analysis. Hypertension, cigarette smoking and involvement of the internal capsule were significantly more frequent in patients with hemorrhagic lacunar stroke than in those with non-lacunar intracerebral hemorrhage, whereas nausea and vomiting, altered consciousness, speech disturbances, hemianopia, and ventricular hemorrhage were significantly less frequent. As compared with non-hemorrhagic lacunar stroke, patients with hemorrhagic lacunar stroke were more likely to have hypertension, sudden stroke onset (minutes), head injury, headache, and basal ganglia involvement and less likely to have diabetes, gradual stroke onset (hours), and dysarthria. After multivariate analysis, only headache (OR 10.14), sudden onset (OR 9.89), and dysarthria (OR 0.10) were independent predictors of hemorrhagic lacunar stroke. Accordingly, the presence of headache and sudden onset of symptoms and absence of dysarthria may be useful signs for distinguishing hemorrhagic lacunar stroke from other causes of lacunar stroke.
