A colour Doppler ultrasound study of venous reflux in patients with chronic leg ulcers.

Abstract

to evaluate the distribution of superficial and deep venous reflux in patients with chronic leg ulcers. retrospective study of 186 patients with chronic leg ulcers (212 lower limbs). in 127 legs without arterial disease and a history of deep venous thrombosis (DVT), 62 (49%) had superficial, 45 (35%) had superficial and deep, and 14 (11%) had isolated deep venous reflux. In legs with a previous DVT, isolated deep venous reflux was more common (21/55, 38%) but superficial reflux, often in combination with deep reflux, still predominated (56%). a large part of the venous insufficiency causing venous leg ulcers is superficial and suitable for varicose vein surgery. In patients with chronic leg ulcers most reflux affects the superficial system and is potentially suitable for surgical correction.
