[Hemichorea improved by carotid artery stenting in a 73-year-old man with hypoperfusion of the basal ganglia].

A 73-year-old man presented with continuous hemichoreic movement of right arm and leg and with dyskinesia in his tongue. Magnetic resonance image (MRI) showed no ischemic lesion within the basal ganglia, but magnetic resonance angiography (MRA) and carotid duplex ultrasonography showed the left internal carotid occlusion and 80% stenosis in the right common carotid artery. Tc-99m-ECD-SPECT showed hypoperfusion of the frontal lobe, temporal lobe, parietal lobe, basal ganglia and thalamus.

Significance of the presence of metabolic syndrome in patients with asymptomatic arteriosclerosis affecting the aorta and the cerebral, extra-cranial carotid and coronary arteries.

Objective: The presence of metabolic syndrome (MetS) is strongly associated with stroke and cardiovascular diseases. However, the relationship between MetS and the localization of atherosclerosis at various sites remains uncertain. In this study, in order to reveal the relevance of MetS to atherosclerosis at several sites, we investigated the relationships among vascular risk factors, asymptomatic cerebral infarction and atherosclerosis in the aorta and carotid and coronary arteries in adults without overtly symptomatic cerebrovascular or cardiovascular disease.

Intra-arterial fibrinolysis via the contralateral internal carotid artery for acute ischemic stroke.

We report a 65-year-old male who suddenly developed consciousness disturbance and left hemiplegia, with tandem embolic occlusions of the right internal carotid artery (ICA) and the middle cerebral artery (MCA). Intra-arterial administration of recombinant tissue plasminogen activator (rtPA) through the right ICA was performed 2.75 hours after onset, but no recanalization of the right ICA was obtained.

[Masseter strength in patients with motor neuron disease].

Although masseter muscles play an essential role in digestion, masseter strength in patients with motor neuron diseases has not been well studied. The purpose of this study is to evaluate the masseter strength in healthy volunteers (n = 13, mean age +/- S.D.
