Post-treatment compression: duration and techniques

Abstract

Background: Compression treatments used the following intervention for varicose veins range from no compression, to elastic stockings and compression bandaging. There is no consensus on the strength or duration of compression which should be applied following a particular treatment. The author reviews the evidence that has led him to reach his own viewpoint on this subject. Summary: Compression stockings are often prescribed after treatment of varicose veins, but these in general exert a much lower pressure in the thigh compared with firm inelastic compression bandages. It has been shown by objective investigation that it takes a pressure of 10–15 mmHg in the supine position and 40–50 mmHg in the standing position to occlude a superficial vein in the thigh. The author has published a study in which three groups of patients were studied following varicose vein surgery. One group received a strong medical compression stocking, the second group an inelastic bandaging system which achieved 63 mmHg compression in the standing position and an eccentric compression system which achieved 98 mmHg in the standing position. Adverse events after surgery were most frequent in the stocking group with fewer in the inelastic compression bandage group and fewest in the eccentric compression group. A further study has been published by another author in which elastic compression has been compared with eccentric compression following endovenous laser ablation of the saphenous vein. Eccentric compression reduced postoperative pain. Unfortunately, very little data are available to indicate the period for which compression should be applied following varicose vein treatment. Conclusions: In comparison to compression treatments following varicose vein surgery where the actual level of compression has been measured, higher levels of compression are more effective than lower levels in moderating postoperative pain and complications. Strong compression can be achieved by inelastic bandaging or by eccentric compression systems. Far fewer data are available to indicate the duration for which postoperative compression is required.
