Cerebral syncope: insights from Valsalva maneuver.
BACKGROUND AND PURPOSE Cerebral syncope refers to a loss of consciousness associated with cerebral vasoconstriction in the absence of systemic hypotension. The diagnosis of cerebral syncope could be established by the head-up tilt test (HUT) and transcranial Doppler ultrasonography. Valsalva maneuver (VM) permitted assessment of cerebral autoregulatory function by provoking blood pressure (BP) ...
متن کاملA Cerebral Air Embolism after Endoscopic Treatment
A 77-year-old man with liver cirrhosis was admitted to our hospital in 2015. He was unconscious and his Glasgow Coma Scale (GCS) score was 10. The Hb level was 3.5 mg/ dL. Contrast CT showed esophageal varices and atrophy of liver, these findings indicated a suspicion of liver cirrhosis. We considered that the varix rupture and the resulting hemorrhagic shock were the main cause of the patient’...
متن کاملCerebral air embolism after pleural streptokinase instillation.
Iatrogenic pulmonary barotrauma and cerebral arterial gas embolism (CAGE) may complicate a variety of medical procedures, such as certain types of surgery, drug administration through thoracic drainage, pneumoperitoneum, cystoscopy, bronchoscopy, etc. Hyperbaric oxygen treatment following the guidelines for CAGE in diving is the treatment of choice. Pleural streptokinase instillation is a commo...
متن کاملCritical closing pressure explains cerebral hemodynamics during the Valsalva maneuver.
The Valsalva maneuver (VM), a voluntary increase in intrathoracic pressure of approximately 40 mmHg, has been used to examine cerebral autoregulation (CA). During phase IV of the VM there are pronounced changes in mean arterial blood pressure (MABP), pulse interval, and cerebral blood flow (CBF), but the changes in CBF are of a much greater magnitude than those seen in MABP, a finding to date a...
متن کاملCerebral hemodynamics during the Valsalva maneuver: insights from ganglionic blockade.
BACKGROUND AND PURPOSE The aim of this study was to differentiate the mechanical effects of the Valsalva maneuver (VM) from the effects of changes in autonomic neural activity on cerebral hemodynamics in humans. METHODS Nine healthy subjects performed the VM before and after autonomic ganglionic blockade with trimethaphan. Blood pressure (BP) was measured in the radial artery with an indwelli...
