    Reviewed herein is the present-day literature data concerning the causes leading to the development of ischemic stroke. Special attention is drawn to the haemodynamic mechanism, of cerebral circulation impairment. Also discussed is the fed of the onset of such disorders in patients suffering from peripheral atherosclerosis during reconstructive surgical vascular interventions, in relation with a multifocal nature of the lesion. Presented are modern findings on diagnostic methods making it possible to assess autoregulatory disorders of cerebral circulation, the main causes of these impairments, as well as potential principles of correction thereof.

    Autoregulation of Blood Flow01:17

    Autoregulation of Blood Flow

    Autoregulation mechanisms are characterized by their inherent capacity for self-regulation without necessitating specific nervous stimulation or endocrine control. These mechanisms facilitate the adjustment of blood flow and, therefore, perfusion specific to each tissue region. This self-regulation encompasses chemical signals and myogenic controls.
    Chemical Signaling in Autoregulation
    Chemical signaling operates at the precapillary sphincter level, inciting either contraction or relaxation.

    Aortic Regurgitation IV: Nursing Management

    A nurse managing a patient with aortic regurgitation begins with a comprehensive assessment, including a review of the patient's medical history, family history, and lifestyle factors. During the cardiac examination, the nurse listens for heart sounds and checks for signs of valve abnormalities. The nurse also observes for symptoms such as dyspnea, orthopnea, and paroxysmal nocturnal dyspnea and assesses the patient's endurance and daily activity tolerance.Based on the findings, the nurse...

    Increased Intracranial Pressure ll: Pathophysiology

    Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
