[Clinical study of 23 patients with ataxic hemiparesis].
OBJECTIVE
To characterize the clinical features, etiology and prognosis in ataxic hemiparesis syndrome.


METHODS
Descriptive study of 23 patients with ataxic hemiparesis included in the Sagrat Cor Hospital of Barcelona Stroke Registry over a 12 year period.


RESULTS
Ataxic hemiparesis was caused by a lacunar infarct in 87% of patients, by atherothrombotic infarcts in 8.7% and by cardioembolic infarct in 4.3%. Ataxic hemiparesis accounted for 0.9% of all acute strokes (n = 2,500), 1.25% of all cerebral infarcts (n = 1,840), and 4.1% of all lacunar infarcts (n = 484). Internal capsule (22%), pons (13%), and corona radiata involvement (9%) were the most frequent cerebral topographies. Absence of in hospital mortality and absence of neurological deficit at discharge from the hospital were present in 39% of the patients.


CONCLUSIONS
Lacune hypothesis is present in ataxic hemiparesis syndrome. Ataxic hemiparesis is caused by a lacunar infarct in 87% of patients. The internal capsule topography is the most frequent and the prognosis in ataxic hemiparesis is good.
