A VRT shorter than 20 seconds is markedly abnormal and is attributable to high volumes of retrograde venous flow. High-volume reflux may occur via the superficial veins, the large perforators, or the deep veins. Patients with this degree of reflux are nearly always symptomatic. When the VRT is shorter than 10 seconds, venous ulcerations are so common as to be considered virtually inevitable.
