Compared to truncal reflux, skin damage is more common with which type of reflux?

Skin damage is more commonly associated with non-truncal reflux rather than truncal reflux. Non-truncal reflux occurs within the superficial venous system, such as with the perforating veins or the saphenous system, which can lead to increased venous pressure in a localized area. This increased pressure can cause venous hypertension, resulting in various skin conditions, including venous ulcers, hyperpigmentation, and dermatitis.

Truncal reflux, which involves the larger, central veins like the great saphenous vein or the small saphenous vein, tends to present with more global symptoms but may not localize the same level of damage to the skin. Therefore, patients with prominent non-truncal reflux are often more susceptible to skin injuries and complications due to the localized effects of the venous reflux.

In summary, the increased risk of skin damage is due to the nature of non-truncal reflux affecting specific areas of the venous network, leading to localized symptoms and complications.
