Induction of angiogenesis via topical delivery of basic-fibroblast growth factor from polyvinyl alcohol-dextran blend hydrogel in an ovine model of acute myocardial infarction.

Hydrogels are currently used as interesting constructs for the delivery of proteins. In this study, a novel polyvinyl alcohol-dextran (PVA-Dex) blend hydrogel was used for controlled delivery of basic-fibroblast growth factor (bFGF). These biocompatible constructs were sutured to the epicardium as patches on the heart surface to provide slow release of bFGF to the infarcted site in an ovine model of myocardial infarction (MI).

Endovenous laser ablation (EVLA) in patients with varicose great saphenous vein (GSV) and incompetent saphenofemoral junction (SFJ): an ambulatory single center experience.

Objectives: To evaluate treatment results for varicose great saphenous vein (GSV) using endovenous laser ablation (EVLA) in an ambulatory single center.

Material And Methods: We prospectively studied 77 limbs with varicose GSV in 74 patients who were treated using 980-nm EVL with a 600-mm laser fiber and the power settings of 10-25 Watts. The patients were followed using color Doppler ultrasound.
