Aims: To assess the effects of superficial venous surgery on anatomic and haemodynamic function in legs with chronic venous ulceration. Methods: Ulcerated legs with an ABPI > 0.85 undergoing surgical correction of superficial venous reflux were studied. Colour duplex imaging and digital photoplethysmography were performed before and 6 weeks following surgery. Legs were stratified into three groups: (A) isolated superficial reflux (n = 44), (B) superficial and segmental deep venous reflux (n = 23), and (C) superficial and total deep venous reflux (n = 12). Results: Seventy-nine limbs with chronic venous ulceration were studied. Superficial venous surgery abolished segmental deep reflux in 9 of the 23 legs (group B) but only abolished total deep reflux in 1 of the 12 legs (group C) (P = 0.03, Chi-square test). Surgery improved median (range) venous refill time from 10 (4–48) to 21 (9–48) s in group A, 11 (4–38) to 16 (6–36) s in group B, and 9 (3–24) to 11 (6–32) s in group C (P < 0.001, P = 0.06 and P = 0.08, respectively). Conclusions: Superficial venous surgery may correct segmental deep venous reflux, but has little effect on total deep reflux. Superficial venous surgery improves venous haemodynamic function in ulcerated limbs with isolated superficial reflux, and may improve haemodynamic function in legs with mixed superficial and segmental deep reflux.
