Objective To investigate the change of vasa vasorum in vessel wall of varicose vein of the lower extre-mity.
Methods Thirty-two patients with varicose vein of the lower extremity were collected, in which of 12 patients with simple varicose veins (varicose group), 9 patients with recurrent varicose veins (recurrent group), 11 patients with
thrombophlebitis of varicose vein (thrombophlebitis group), 9 patients with normal venous tissue as control group. HE staining was performed to observe the distribution of vasa vasorum and detect the vasa vasorum density.
Results The increasing vasa vasorums were observed in the adventitia and media, but few was observed in the intima in the varicose, recurrent, and thrombophlebitis groups. The distribution of vasa vasorum was in the adventitia in the control group. The vasa vasorum densities (/mm2) in the varicose, recurrent, and thrombophlebitis groups (5.65±1.45,6.20±
1.73, and 5.94±1.63, respectively) were greater than those in the control group (2.87±0.54), the difference was
statistically significant (P<0.05), but there was no significant difference of the vasa vasorum density among the varicose
vein, recurrent, and thrombophlebitis groups (P>0.05).
Conclusion Change of vasa vasorum is an important pathol-
gical change with the nosogenis of varicose vein of the lower extremity.
