Non-truncal reflux is most commonly seen in which gender?

Non-truncal reflux, which refers to venous reflux that occurs in the branch veins rather than the main saphenous vein, is more frequently observed in females. This is primarily due to several factors, including the hormonal influences on venous structure during puberty and pregnancy. Females typically experience changes in blood volume and venous tonicity influenced by estrogen and progesterone, which can lead to an increased propensity for venous insufficiency and subsequent reflux. Additionally, anatomical differences in the lower extremities between genders, such as the distribution of subcutaneous fat and the presence of larger numbers of smaller veins in females, may contribute to the higher incidence of non-truncal reflux.

The implications of this knowledge are significant for clinicians specializing in phlebology, as understanding the gender differences can assist in diagnosing and treating venous disorders effectively.
