“…It was expressed in %. RVF – is closely related to ambulatory venous pressure, indirectly representing it in a linear way. 14 Therefore, it has been used as a non-invasive method to determine the venous pressure on the superficial venous system. It was determined by calculating the limb volume remaining after 10 tiptoe movements divided by VV and multiplied by 100.…”

Objective Analyse venous haemodynamics in healthy primigravidae during pregnancy and in the postpartum. Methods Cohort with primigravidae evaluated in the three trimesters of pregnancy and postpartum. Duplex evaluated venous diameters and reflux; air plethysmography evaluated venous filling index, ejection fraction, residual volume fraction and outflow fraction in both limbs. Results During pregnancy, diameters increased in bilateral common femoral and right infravalvar great saphenous, but returned to first trimester values after delivery. Reflux developed in one woman (5%) in the second trimester and in two more women (15%) in the third trimester. No reflux was detected in postpartum. Bilateral venous filling index was higher during pregnancy. Bilateral ejection fraction and residual volume fraction did not change. Bilateral outflow fraction increased progressively. The right limb outflow fraction in left lateral decubitus was similar. All changes returned to first trimester values after delivery. Conclusions Healthy primigravidae presented changes in lower limbs' veins during pregnancy: diameters in bilateral common femoral and infravalvar great saphenous veins increased; new reflux was developed in 15% of women, but there was no venous hypertension. Calf muscular pump function did not change. All changes returned to first trimester values after delivery.

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.

Venous incompetence in the lower extremity is a common clinical problem. Basic understanding of venous anatomy, pathophysiologic mechanisms of venous reflux is essential for choosing the appropriate treatment strategy. The complex interplay of venous pressure, abdominal pressure, venous valvular function and gravitational force determine the venous incompetence. This review is intended to provide a succinct review of the pathophysiology of venous incompetence and the current role of imaging in its management.
