“…It has also been observed in the literature that the iliofemoral segment of the deep venous system is the most favorable site for thrombus formation in pregnant women in contrast to the non-pregnant state, where soleal sinuses of the calf are the site for the thrombus formation initiation. 9,18,19 The choice of this vein for evaluation of venous system using spectral Doppler seems very reasonable for screening pregnancy-related changes at the early stage of venous insufficiency. Second, evaluation of the entire venous system of the lower limb is not practical as prolonged lying down in the supine position might cause inferior vena cava syndrome and due to difficulty of positioning required for adequate visualization of all the veins of lower limb.…”

Objective: Pregnancy can induce the slowing of blood flow in the lower extremity veins and associated complications such as varicose veins. The objective of this study was to report the hemodynamic alterations in uncomplicated pregnancies during second and third trimesters using spectral Doppler. The specific aim was to compare the venous diameter and mean flow velocities of maternal common femoral veins (CFVs) during second and third trimesters of pregnancy. This was designed to assess the extent of pregnancy-induced hemodynamic changes as well as to establish a normative range of these values. Materials and Methods: This cohort study was conducted with 230 women during second and third trimesters of pregnancy. Grayscale sonography and spectral Doppler were used to record the diameter and mean flow velocity of maternal CFVs bilaterally. An independent sample t test was performed for the comparison of these between women with second and third trimesters of pregnancy. Statistical significance was set a P ≤ .05, a priori. Results: There was significant dilatation and a corresponding decrease in mean blood flow velocities in the CFVs in the participants in their third trimester compared with the second trimester of pregnancy. Conclusion: In this large cohort of participants, the CFV demonstrated statistically significant distension and slowing of blood flow with the advancement of their pregnancies.
