A prospective double-blind randomized controlled trial of radiofrequency versus laser treatment of the great saphenous vein in patients with varicose veins.

Background: Endovenous ablation of varicose veins using radiofrequency ablation (RFA) and endovenous laser therapy (EVLT) has reported advantages over traditional open surgical treatment. There is little evidence comparing the efficacy and patient-reported outcomes between the 2 endovenous solutions. This study compares the RFA and EVLT strategies in a prospective double-blind clinical trial.

The first endovascular repair of an acute type A dissection using an endograft designed for the ascending aorta.

Endovascular repair has emerged as a potential alternative to emergency open surgical repair for type A dissection in selected patients, with isolated reports describing the results obtained with a range of devices designed originally for the descending aorta. We believe that we present the first reported repair of an acute ascending aortic dissection using an endovascular stent graft manufactured specifically for the ascending aorta.
