Aims and objectives
Based on theoretical considerations injectable hyaluronan gels offer three options to treat venous insufficiency: 1) Percutaneous valvuloplasty (PVP),
aiming at the restoration of local valve function in insufficient veins with still intact and mobile valvular structures (Fig.1/2).
2) Focal venoplasty (FVP),
aiming to produce a focal diameter reduction independent of valvular structures in order to reduce reflux (Fig.3/4).
3) Segmental venoplasty (SVP), determined to replace the standard saline tumescent technique by producing a long-term and long-distance diameter reduction as an adjunct to endoluminal procedures for saphenous veins aiming to reduce the inflammatory sideeffects of the procedure (Fig.
5/6/7).
