Focus of the Report: The focus of this Health Technology Assessment (HTA) is to evaluate the safety and effectiveness of cyanoacrylate embolization (CAE) with the VenaSeal closure system (Medtronic Inc.) to treat symptomatic varicose veins. This HTA also compares the effectiveness and safety of the VenaSeal closure system with other endovenous treatments and surgical vein stripping.
Technology Description: The VenaSeal closure system is approved for the permanent closure of lower extremity superficial truncal veins through nonthermal endovascular CAE with coaptation in adults with clinically symptomatic venous reflux as diagnosed by duplex ultrasound. CAE is performed in an outpatient setting and provides a nonthermal, endovenous technique that does not require tumescent anesthesia or compression stockings or wraps following treatment and allows for reduced procedural time, quicker recovery time after treatment, and reduced likelihood of nerve damage and hematoma.
Controversy: The use of nonthermal nontumescent endovenous techniques, such as coaptation with a cyanoacrylate adhesive, is thought to improve patients’ perioperative experiences, as it does not require tumescent anesthesia or compression stockings or wraps following treatment. However, controversy surrounds the comparative effectiveness of this system with other endovenous techniques and whether long-term effects are sustained after treatment.
