Background:
Analyze the association of lower limb edema with venous reflux in healthy primigravidae during pregnancy and in the postpartum.
Methods:
Cohort with primigravidae evaluated in the three trimesters of pregnancy and postpartum. Edema was assessed by physical examination. Duplex evaluated venous reflux in both limbs.
Results:
In the first trimester, no woman presented edema or venous reflux. In the second trimester, venous reflux was found in one patient (5%) and edema was found in four women (20%). Venous reflux and edema were not associated (P=1). In the third trimester, two other patients developed venous reflux (15%) and eleven women developed lower limb edema (55%). Venous reflux and edema were also not associated (P=0.21). In the postpartum period, neither venous reflux nor lower limb edema were found.
Conclusions:
In healthy primigravidae, lower limb edema was not associated with venous reflux. Both were present in the second and in the third trimesters of pregnancy and resolved spontaneously in the postpartum period. Both are products of the same physiological changes that occur in pregnancy.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
