Introduction. The involvement of pathological segmental venous hypervolemia of the lower leg in patients with varicose veins in the formation of chronic venous insufficiency (CVI) is an established fact, however, objective criteria for this pathohemodynamic phenomenon have not been definitively determined today.The purpose of the study. Determination by air plethysmography (APG) of the degree of functional disorders in the limb and establishment of significant criteria characterizing pathological segmental hypervolemia of the lower leg in patients with CVD of various clinical classes according to CEAP.Materials and methods. For the period from 2002 to 2019, 380 healthy individuals with no symptoms of chronic venous diseases and 896 patients with CVD were examined with the use of APG, with their distribution in accordance with the CEAR international classification as follows: C0–C1, C2–C3, C4–C6 clinical classes. To assess the intensity of venous blood flow, the following values were calculated: the maximum capacity of the leg veins (Venous Capacity – VC), the volume of their evacuation (Evacuation Volume – EV) for a set time, the maximum venous outflow (Maximum Venous Outflow – MVO), the ratio of these values on both limbs (Venous Capacity Index – VC1, Evacuation Volume Index – EVI, Maximum Venous Outflow Index – MVOI).Results. The most statistically significant and conjugate correlation data were obtained (expectation, mean square deviation, standard error of expectation, median and coefficient of variation) during the analysis in groups according to the characteristic VCI.Discussion. The obtained results allowed us to assert that APG is an informative functional method for diagnosing hemodynamic disorders in patients with lower limb CVD.Conclusion. The established criteria of the venous capacity index will allow in practice to give an objective characterization of the degree of change in hemodynamic disorders in patients with CVD before and after the treatment undertaken.

Air plethysmography is a non-invasive test that can quantify venous reflux and obstruction by measuring volume changes in the leg. Its findings correlate with clinical and hemodynamic measures. It can quantitatively assess several components of venous hemodynamics: valvular reflux, calf muscle pump function, and venous obstruction. Although clinical uses of air plethysmography have been validated, it is used almost exclusively for medical research. Air plethysmography can be used to assess chronic venous disease, to evaluate improvement after venous surgery, to diagnose acute and past episodes of deep venous thrombosis, to evaluate compression stocking therapy, to study the physiological implications of high-heeled shoes in healthy women, and even to evaluate the probability of ulcer healing.

Background: There is growing global interest in validated health assessment instruments. In order to use these instruments in different countries, it is necessary to conduct translation, cultural adaptation and validation in the target language. In Brazil, there are few instruments for assessment of the impact of chronic venous disease (CVD) on the quality of life (QoL) of patients. Objective: To validate the AVVQ-Brazil. Method: This was an analytical, observational study to validate the AVVQ questionnaire with 107 individuals with CVD. The version of the AVVQ adapted for Brazilian Portuguese was administered three times. The first two administrations were successive, with a 30-minute interval (interobserver reproducibility) and the third administration took place 7 to 15 days later (intraobserver reproducibility). Internal consistency and validity were also assessed. Results: A total of 107 people took part, 87.9% were female, mean age was 50.1 years ± 14.7; the majority had spent long periods standing up (57.0%) throughout their lives and did not engage in physical exercise (96.3%). Many had not completed primary education (25.2%); were members of economic class C2 (36.4%); and had disease severity class C4 (22.4%) or C6 (23.3%) on the CEAP scale. Interobserver and intraobserver reliability of the AVVQ were excellent. Internal consistency was excellent to moderate for the majority of domains. Spearman correlations showed that total AVVQ score and its Pain and Dysfunction domains were negatively correlated with all SF-36 domains. The Mann-Whitney test showed that patients with CEAP 1, 2 or 3 exhibited differences that were statistically significant from those with CEAP 4, 5 or 6 for total AVVQ scores and for Complications domain scores. Conclusions: The AVVQ has been validated for Brazil and can now be used.
