Studies researching cyanoacrylate closure with the VenaSeal™ closure system have been limited to moderate-sized great saphenous veins, and some have mandated postoperative compression stockings.
WAVES reports the results of cyanoacrylate closure for the treatment of the great saphenous vein (GSV), small saphenous veins (SSV), and/or accessory saphenous veins (ASV) up to 20 mm in diameter without the need for compression stockings.†
Rasmussen randomized clinical trial note: 500-patient, randomized, controlled clinical trial comparing endovenous laser ablation, radiofrequency ablation, ultrasound-guided foam sclerotherapy, and surgical stripping for great saphenous varicose veins.
† Includes nine roll-in patients whose data were not included in this analysis.
