ABSTRACT
BACKGROUND:
The mechanism of lacunar stroke (LS) is rather speculative due to the lack of neuropathological evidence in clinical practice. To explore the significance of the occlusion site of the lenticulostriate artery (LSA) to this mechanism, we investigated the characteristics and prognosis of patients with LS with proximal occlusions. MATERIALS ANDMETHODS:
We studied 202 patients with acute LS in the region of the LSA. The presumed occlusion site of the LSA was assessed on coronal, diffusion-weighted magnetic resonance images. Based on the distance from the basal surface of the hemisphere to the proximal site of the lacunar infarct, patients were divided into 3 groups proximal, middle, and distal site occlusions, and their characteristics and outcomes were compared.RESULTS:
White blood cell counts, blood glucose, hemoglobin A1c, low-density lipoprotein cholesterol, triglyceride, and admission National Institutes of Health Stroke Scale score were statistically different among the 3 groups. In multivariate analysis, both high levels of white blood cells (odds ratio [OR], 1.16; 95% confidence interval [CI], 1.01-1.33) and triglyceride (OR, 1.31; 95% CI, 1.09-1.61) were positively related to the proximal occlusion site. Proximal occlusion (OR, 3.98; 95% CI, 1.06-16.11) was related to poor outcome at discharge.CONCLUSIONS:
Proximal occlusion of the LSA was independently related to elevated triglyceride and white blood cell counts. Patients with LS with proximal LSA occlusion had severe neurological deficits both on admission and at discharge.Palavras-chave
