Progressing small vessel pontine infarction includes different etiologies

چکیده
BACKGROUND The aim of this study was to investigate the clinical features of progressing stroke of pontine infarction as small vessel disease. METHODS Enrolled 38 acute pontine infarctions were confirmed by magnetic resonance imaging and magnetic resonance angiography at the first and seventh days. Ten patients (26.3%) presented progression (NIH Stroke Scale ≥2 increase within 72 h). RESULTS Progressing patients showed no relation to the size and the distribution of lesion. Expansion of ischemic lesion showed correlation with basilar artery atherosclerosis. Stable lesion related to delayed worsening. CONCLUSION These findings suggest that progressing stroke may be caused by not only the worsening of blood flow of ischemic lesion but also delayed neuronal death.

Basilar artery atherosclerotic plaques in paramedian and lacunar pontine infarctions: a high-resolution MRI study.
BACKGROUND AND PURPOSE Pontine infarction is most often related to basilar artery atherosclerosis when the lesion abuts on the basal surface (paramedian pontine infarction), whereas small medial pontine lesion is usually attributed to small vessel lipohyalinosis. A previous study has found that high-resolution MRI can detect basilar atherosclerotic plaques in up to 70% of patient with paramedia...

BACKGROUND In this retrospective study, we investigated the main pathogenesis of the two types of isolated pontine infarction: paramedian pontine infarcts (PPIs) and small deep pontine infarcts (SDPIs). METHODS Acute ischemic stroke patients, comprising 117 PPI patients and 40 SDPI patients, were enrolled. High-resolution magnetic resonance imaging (HR-MRI) and routine MRI sequences were perf...

BACKGROUND AND PURPOSE Detailed data on the occurrence of swallowing dysfunction in patients with recent small subcortical infarcts (RSSI) in the context of cerebral small vessel disease are lacking. This prompted us to assess the frequency of and risk factors for dysphagia in RSSI patients. METHODS We identified all inpatients with magnetic resonance imaging-confirmed RSSI between January 20...
متن کاملHeparin for lacunar stroke in progression.
Four patients with mild hemiparesis were treated with heparin for presumed progressing stroke. All worsened to hemiplegia with pure motor deficits and lacunar infarcts despite this medical intervention. Clinical distinction between large artery and small, penetrating vessel thrombotic disease is needed to best evaluate any benefit of anticoagulation for stroke in progression.
