Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Venous leg ulcers (VLUs) are a common wound with significant morbidity and cost, and suboptimal therapeutic options. VLUs result from chronic venous insufficiency, including venous reflux and post-thrombotic syndrome. VLU can take from months to years to heal, and 54-78% recur. Current therapies include wound, compression therapy, and medications. These treatments can increase the rate of healing, and reduce recurrence, however these therapies can be burdensome, painful, and ineffective, and despite these therapies, \~50% of wounds become chronic. Chronic VLUs can be painful, malodorous, and infected, and they often significantly limit an individual's function and mobility. An emerging therapy for symptomatic venous reflux is the closure of the culprit vein by endovenous closure with a cyanoacrylate adhesive implant. Recent studies show cyanoacrylate closure (CAC) to be a safe and effective treatment for varicosities resulting from symptomatic incompetent great saphenous veins. This study will evaluate the safety and effectiveness of CAC for VLUs.
