Subfascial endoscopic perforator vein surgery combined with saphenous vein ablation: results and critical analysis.

Abstract

This study was undertaken to determine the results of subfascial endoscopic perforator vein surgery (SEPS) combined with ablation of superficial venous reflux. Clinical data were retrospectively analyzed for 74 consecutive limbs (65 patients) in which this combination treatment was performed at a university medical center. Preoperatively, 58 lower extremities had an open venous ulcer (CEAP clinical class 6 [C(6)]) and 16 had healed ulceration (C(5)). Preoperative and postoperative ulcer care remained constant. Main outcomes measured included perioperative complications, ulcer healing, and ulcer recurrence. Clinical severity and disability scores were tabulated before and after surgery. Mean patient follow-up was 44 months. Greater saphenous vein (GSV) stripping and varicose vein excision accompanied SEPS in 57 limbs (77%), and SEPS was performed alone or with varicose vein excision in 17 limbs that had previously undergone GSV stripping. Postoperative complications occurred in 12 limbs (16%), all with C(6) disease (P =.04). Ulcer healing occurred in 91% (53 of 58) of limbs with C(6) disease at a mean of 2.9 months (range, 13 days-17 months). Multivariate analysis demonstrated that ulcer healing was negatively affected by previous limb trauma (P =.011). Ulceration recurred in 4 limbs (6%) at 7, 20, 21, and 30 months, respectively. This was associated with a history of limb trauma (P =.027) and preoperative ultrasound evidence of GSV reflux combined with deep venous obstruction (P(R,O); P =.043). Clinical severity and disability scores improved significantly after surgery (both, P <.0001). Most venous ulcers treated with SEPS with ablation of superficial venous reflux heal rapidly and remain healed during medium-term follow-up. Ulcer healing is adversely affected by a history of severe limb trauma, and ulcer recurrence is similarly affected by a history of limb trauma in addition to superficial venous reflux combined with deep venous obstructive disease. Overall, there was marked improvement of postoperative clinical severity and disability scores compared with those obtained before surgery.
