Abstract
The high rate of groin recurrences in varicose vein surgery has established a
need for methods to prevent them.
The use of different barrier techniques in the groin helps in reducing the reflux
rate to 1.5 and 3 % within two to five years after the primary operation.
Electrocoagulation of the stump endothelium with suturing of the lamina cribrosa
and extensive crossectomy with stump oversuturing represent the most simple
techniques. Even so, recurrence at the saphena femoral junction cannot be
prevented in all cases. The remodelling hypothesis of varicose vein genesis,
which includes chronic inflammatory processes, as well as further factors
associated with recurrence seem to play a significant role in the
pathophysiologic process. Therefore, in addition to barrier techniques
conservative anti-inflammatory procedures should also be included in the therapy
program: Vein-conscious lifestyle with compression-therapy, avoiding long
sitting and standing, endurance sports and in case of obesity reduction of
visceral fat tissue. Studies addressing this nonsurgical type of recurrence
prevention are lacking.
