Speckle-optical characteristics of microhemodynamics of the temporal region skin in patients with arterial aneurysms

Abstract

The possibility of application of the speckle-optical method for the objectivization of cutaneous blood flow and evaluation of vascular reactivity with respiratory arrest and hyperventilation is shown. 21 patients with arterial aneurysms (AA) of the brain were examined. Recording of blood flow was carried out on skin of the temporal region on both sides. Violation of vascular reactivity during respiratory tests in the form of development of paradoxical reactions or reduction of adequate responses to HF and HB on the side with AA has been established. The most informative are the power of the spectrum and the mean frequency of the spectrum.
