In twenty patients with primitive venous hypertension and in ten healt
hy subjects we have determined the plasmatic levels of: Thrombomodulin
(TM), beta-Thromboglobulin (beta-TG), D-Dimer (DD), the tissue activa
tor of the plasminogen (t-PA) and the inhibitor of the activator of th
e plasminogen (PAI-I), The levels of the parameter we studied have sho
wn in the patients a significant difference of beta-TG (p<0.01) and PA
I-1 (p<0.01) compared to the controls, whereas there was no significan
t difference in the other parameters we studied. Our data underline, i
n patients with primitive venous hypertension, the importance that the
activation of the platelets and the reduction of the potential fibrin
olytic can assume, together with the stasis, regarding the onset of th
rombotic complications.
