추골뇌기저동맥 순환부전을 동반한 어지럼 환자의 임상 양상

Abstract

Background and Objectives：Dizines is the most common symptom of vertebrobasilar insuficiency (VBI), occurring in at least two-thirds of patients. The aim of our study is to document the clinical features and the treatment outcomes in the dizzy patients with VBI. Subjects and Method：performed at a tertiary referral center. Results：The most frequent type and duration of dizzines were rotational (52.8%) and minute (55.6%). Sixten patients (44.4%) reported that their episodes of dizziness occurred several times per a month. Half of the patients had at least one isolated episode of dizziness and in 25% VBI began with an isolated episode of vertigo. Twenty-thre patients (63.9%)and 38.9% had a significantly decreased or absent response to caloric stimulation. On the dynamic posturography, visual dys-function (33.4%) and vestibular dysfunction (19.4%) were observed. Thirty-two patients (88.9%) had abnormal finding on the pure tone audiometry. Nineteen (61.3%) of 31 patients experienced resolution or significant reduction of their episodes of dizzi-nes with treatment. But one patient progresed to acute infarction. Conclusion：VBI-asociated dizzines cause various clinical manifestations and there should be relevant diferential diagnosis for episodic vertigo that last only minutes. We should pay special attention to the VBI in patients with isolated, transient dizziness and the risk factor of the cerebrovascular disease.
