Changes in the diameter and valve closure time of leg veins in primigravida women during pregnancy.

Objective: The aim of this study was to monitor the changes that develop in leg veins of primigravida women during pregnancy.

Methods: Sixty primigravida women volunteered to undergo clinical evaluation and duplex ultrasound examination of both lower limb veins to monitor changes in vein diameter and valve closure time (VCT) during pregnancy and 3 months postpartum by duplex ultrasound. A total of four readings were taken for each subject, one reading for each trimester and the last reading at 3 months postpartum.
