Methods and materials
PVP was studied in 22 patients with the aim to treat insufficient terminal or preterminal GSV valves (14 f,
8 m,
32 – 54 y.,
GSV diameter 7.0 – 12.0 mm),
using a prototype hyaluronan (XL type,
maximum durability,
Vivacy).
FVP was evaluated in 16 patients (11 f,
5 m,
46 – 69 y.) for reflux reduction in GSV or sidebranch insufficiency (L-type,
medium durability,
Vivacy).
SVP was investigated in 20 cases (13 f,
7 m,
41 – 72 yrs.) with GSV or SSV insufficiency,
adjunctive to Biomatrix sclerofoam (Venartis),
using another hyaluronan (S-Type,
short durability,
Vivacy).
For this collective,
target segments were split and randomized to hyaluronan vs.
NaCl 0,9%.
Clinical inspections an sonographic controls where carried out after 2,
12 and 26 weeks.
