Hypotension as cause of TIAs (transient ischemic attacks) in patients with severe carotid stenosis and hypertension.
TIAs (Transient Ischemic Attacks) in hypertensive patients with cerebrovascular disease may be caused by a quick decrease of blood pressure. Neurological deficits are possible in patients with critical or subcritical stenoses of vertebral or carotid arteries. In these conditions different flows cause different decreases with the same level of stenosis. So when pressure and flow decrease, the relative importance of stenosis increase and patients may have TIAs. In 10 hypertensive patients with critical arterial stenosis this consequence of clinical events was observed and registered.
