2.Vertigo of cerebrovascular origin proven by CT scan or MRI: pitfalls in clinical differentiation from vertigo of aural origin.
Yonsei Medical Journal 1996;37(1):47-51
To get a better insight into the clinical differentiation between vertigo of cerebrovascular origin and of aural origin, we investigated radiologically proven stroke patients who presented with vertigo as an initial clinical manifestation. Of 154 stroke patients, 30 patients with vertigo (20%) had the relevant lesion, demonstrated with the initial computerized tomographic scan (13 patients) or the follow-up magnetic resonance imaging (MRI) study (17 patients) of the brain. Every lesion was in the vertebrobasilar arterial territory; 19 in the cerebellum, 8 in the pons, and 3 in the medulla oblongata. Although 12 of the 30 patients (40%) presented with vertigo in isolation at the onset of stroke, eight patients (27%) developed additional neurologic abnormalities from four hours to seven days later. Patients with isolated vertigo (13%) had the small lesion exclusively in the cerebellum of the PICA medial branch territory. The most frequent accompanying neurological sign was swaying in the cerebellar and medullary lesion, and dysarthria in the pontine lesion. The direction of nystagmus or swaying did not match the lesion side in some patients. Our findings suggest that cerebellar stroke may commonly manifest isolated vertigo or vertigo with swaying mimicking labyrinthine disorder, particularly at the onset of the disease. MRI study and tests for truncal ataxia and lateropulsion may be crucial for the detection of vertigo of cerebrovascular origin.

The delayed-onset focal or segmental dystonia is a rare sequelae of cerebrovascular disease. The responsible lesion sites for the dystonia are variable and the pathogenesis is uncertain. This study reports three patients with delayed-onset focal dystonia as a complication of stroke. The interval between hypoxic insult and onset of dystonia were varied from 1 month to 1 year. Two adults and one child had focal lesions at the contralateral basal ganglia. The interval between the brain damage and dystonia did not appear to be related to the age at the time of hypoxic injury. The site of lesions may serve as an important factor in the pathogenesis.

BACKGROUND/AIMS: The CHADS2 score, used to predict the risk of ischemic stroke in atrial fibrillation (AF) patients, has been reported recently to predict ischemic stroke in patients with coronary heart disease, regardless of the presence of AF. However, little data are available regarding the relationship between the CHADS2 score and cardiovascular outcomes. METHODS: This was a retrospective study on 104 patients admitted for acute coronary syndrome (ACS) who underwent coronary angiography, carotid ultrasound, and transthoracic echocardiography. RESULTS: The mean age of the subjects was 60.1 +/- 12.6 years. The CHADS2 score was as follows: 0 in 46 patients (44.2%), 1 in 31 (29.8%), 2 in 18 (17.3%), and > or = 3 in 9 patients (8.7%). The left atrial volume index (LAVi) showed a positive correlation with the CHADS2 score (20.8 +/- 5.9 for 0; 23.2 +/- 6.7 for 1; 26.6 +/- 10.8 for 2; and 30.3 +/- 8.3 mL/m2 for > or =3; p = 0.001). The average carotid total plaque area was significantly increased with CHADS2 scores > or = 2 (4.97 +/- 7.17 mm2 vs. 15.52 +/- 14.61 mm2; p = 0.002). Eight patients experienced cardiovascular or cerebrovascular (CCV) events during a mean evaluation period of 662 days. A CHADS2 score > or = 3 was related to an increase in the risk of CCV events (hazard ratio, 14.31; 95% confidence interval, 3.53 to 58.06). Furthermore, LAVi and the severity of coronary artery obstructive disease were also associated with an increased risk of CCV events. CONCLUSIONS: The CHADS2 score may be a useful prognostic tool for predicting CCV events in ACS patients with documented coronary artery disease.
