Endovenous saphenous ablation corrects the hemodynamic abnormality in patients with CEAP clinical class 3-6 CVI due to superficial reflux.

This investigation was designed to determine whether minimally invasive radiofrequency or laser ablation of the saphenous vein corrects the hemodynamic impact and clinical symptoms of chronic venous insufficiency (CVI) in CEAP clinical class 3-6 patients with superficial venous reflux. Patients with CEAP clinical class 3-6 CVI were evaluated with duplex ultrasound and air plethysmography (APG) to determine anatomic and hemodynamic venous abnormalities. Patients with an abnormal (>2 mL/second) venous filling index (VFI) and superficial venous reflux were included in this study.

Recurrence of chronic venous ulcers on the basis of clinical, etiologic, anatomic, and pathophysiologic criteria and air plethysmography.

Introduction: Leg ulcers associated with chronic venous insufficiency (CVI) frequently recur after healing. The risk of recurrence has not been well defined for patients in different anatomic and hemodynamic groups. We reviewed the risk of ulcer recurrence on the basis of clinical, etiologic, anatomic, and pathophysiologic criteria and hemodynamic characteristics of the affected limb as assessed with air plethysmography (APG).
