Abstract
Aim. To determine the diagnostic capabilities of the method of plethysmography so as to assess endothelial function in patients of surgical profile. Materials and methods. Endothelial function indices were measured with plethysmography using postocclusive reactive hyperemia tests in 20 thoracic patients before and after the thoracic surgery and in practically healthy subjects diagnosed local lipodysfunction before and after the lipoaspiration. Results. In patients of thoracic profile, significant decrease in reflection index and rise in hardness index immediately after the surgery, as well as significant growth of hardness index on the day 5 th after the intervention was detected. Endothelial function index has a tendency to lower in thoracic patients as compared to healthy persons. Conclusion. Plethysmography using occlusive test is a simple, easy, informative method of determination of endothelial dysfunction degree in thoracic patients.
