Endovenous Ablation of Incompetent Perforator Veins Is Effective Treatment for Recalcitrant Venous Ulcers

Abstract

Objectives: Endovenous closure of incompetent saphenous veins has been reported to facilitate venous ulcer healing; however, there is little information about the effectiveness of perforator ablation (PA) in healing recalcitrant venous ulcers. We report our experience with PA with venous ulcers unresponsive to prolonged compression therapy. Methods: Patients with nonhealing venous ulcers of >3 months' duration underwent duplex ultrasound imaging to assess their lower extremity venous system for incompetence of superficial, perforating, and deep veins. Patients who had either no saphenous incompetence or persistent ulcers after saphenous ablation underwent PA of incompetent perforating veins >3 mm that demonstrated reflux; initial treatment was performed on the perforator vein adjacent to the ulcer, with additional incompetent veins treated if ulcer healing failed. Results: Fifty-six ulcers with 74 associated incompetent perforating veins were treated with PA in 44 patients with CEAP 4 (9%), 5 (6%), and 6 (85%) recalcitrant venous ulcers. Treated incompetent perforator veins were located in the medial ankle (67 %) and calf (33%). Initial success of PA, assessed by postprocedure duplex ultrasound imaging, was 55 %; reported complications of catheter site skin necrosis (0%), infection (0%), and nerve injury (0%) did not occur. In 18% of patients, more than one procedure was required for perforator closure; 73% had eventual successful perforator closure. Failure of perforator closure occurred in 27% and was associated with intercurrent illness, patient noncompliance, and patient death from unrelated causes. Of patients whose ulcers healed, the healing occurred at a mean of 2.3 months; an average PA of 1.5 incompetent veins per ulcer were required for healing. Conclusions: This experience demonstrates both the feasibility and effectiveness of PA for a selected group of patients with venous ulcers who fail conventional therapy with compression.
