Primary orthostatic cerebral ischaemia.

R J Stark, J Wodak

    Journal of Neurology, Neurosurgery, and Psychiatry
    |October 1, 1983
    PubMed
    Summary
    This summary is machine-generated.

    Four patients with primary orthostatic cerebral ischemia, a condition causing dizziness upon standing, were treated effectively. Surgical intervention improved symptoms, highlighting a distinct cerebrovascular disease presentation.

    Area of Science:

    • Neurology
    • Vascular Surgery

    Background:

    • Primary orthostatic cerebral ischemia is a poorly documented syndrome.
    • Patients present with symptoms like dizziness or syncope upon standing, distinct from classical transient ischemic attacks.

    Observation:

    • Four patients experienced orthostatic symptoms without significant systemic blood pressure drops.
    • Physical examination revealed bruits over neck vessels or absent pulses.
    • Cervical angiography demonstrated widespread narrowing or occlusion of major cerebral arteries.

    Findings:

    • Carotid endarterectomy successfully relieved orthostatic symptoms in all patients.
    • The surgical procedure also mitigated the drop in retinal artery pressure upon standing.

    Implications:

    Related Experiment Videos

    • Recognizing primary orthostatic cerebral ischemia is crucial for accurate diagnosis of cerebrovascular disease.
    • Cervical artery stenosis should be considered in patients with unexplained orthostatic symptoms.
    • Surgical revascularization offers a viable treatment option for this condition.
