[Mobile thrombi in the cervical carotid artery].

Clinical characteristics of mobile thrombus in the cervical carotid artery were investigated. In the 1,528 patients with acute ischemic stroke, mobile thrombi were detected by carotid echography in 14 patients (0.9%; mean 77 years-old; 8 women). Mean National Institutes of Health Stroke Scale was 19 on admission, and 24 on day 10. Mean modified Rankin Scale was 4.6 (dead in 2 patients) at discharge. MR angiography disclosed occlusion of the internal carotid artery in 11 of 14 patients. Mobile thrombi were divided into 3 subtypes: floating thrombus in 5 patients; mobile mural thrombus in 5; oscillating thrombus in 4. Followed echography showed occlusion of the internal carotid artery in 4 of 7 patients. Floating thrombus disappeared in one of 5 patients without clinical recurrence. Although surgical treatment including carotid endarterectomy was not performed in all of the present cases, clinical recurrence during admission was seen in only one patient with embolic stroke in the contralateral internal carotid artery of the mobile thrombus.

[Serial magnetic resonance images in patient with the middle cerebral artery dissection].

A 30-year-old man suffered from transient left hemiparesis and was admitted under the clinical diagnosis of transient ischemic attack. Cerebral angiogram on admission disclosed severe stenosis at the horizontal portion of the right middle cerebral artery. Magnetic resonance images (MRI) on axial view showed a linear enhanced lesion along the stenosis. Images on sagittal view disclosed a crescent-like lesion surrounding a flow void of the middle cerebral artery. After administration of aspirin, he had never suffered from hemiparesis. The enhanced lesion of the middle cerebral artery gradually disappeared on MRI. Although the middle cerebral artery showed temporary improvement of the stenotic lesion, it finally occluded 9 months after the onset. A diagnosis of spontaneous dissection of the right middle cerebral artery was made. The process of the arterial hemodynamics, such as a shrinking of the pseudo-lumen and a flow improvement in the true lumen, was well documented on serial MRI with Gd-DTPA and serial MRA.

[Respiratory infectious complications after acute ischemic stroke].

BACKGROUND AND PURPOSE: Respiratory infection is a frequent complication in acute ischemic stroke, but it seems to have been made light of in stroke care. The purpose of this study is to examine the clinical characteristics of respiratory infectious complications in patients with acute ischemic stroke. METHOD: Two-hundred and fifty-eight consecutive patients (158 men, 100 women, 70.6 +/- 12.9 years old) with acute ischemic stroke were admitted to our hospitals between May and October in 1999. Age, gender, history of stroke, the severity of stroke on admission, stroke subtype (lacunar brain infarction, atherothrombotic brain infarction, cardioembolic brain infarction, and others), aspiration, naso-gastric tube feeding, vascular risk factors, the length of hospital stay and outcome of patients were noted. We compared them between patients with and without respiratory infections. RESULTS: Forty-five (17.4%) patients were developed respiratory infections. Cardioembolic stroke patients were more frequently developed respiratory infections (67%) compared with other stroke subtypes. The independent risk factors for respiratory infectious complications by multiple logistic regression model were the aspiration (OR, 5.513; 95% CI, 1.793-16.946) and the severity of stroke on admission (OR, 1.090; 95% CI, 1.034-1.150). Mortality of patients with respiratory infectious complications was as high as 24%, and all survivors discharged to another hospital. After adjustment for age and the severity of stroke, respiratory infection was one of the independent risk factors of poor stroke outcome (OR, 5.838; 95% CI, 1.792-19.018). CONCLUSION: Aspiration and the severity of stroke independently predict development of respiratory infectious complication in acute ischemic stroke. Respiratory infections may make worse their stroke outcome. A measure to infectious complications and aspiration needs to be taken for the patients suffering from severe ischemic stroke.
