Diastolic compression device aimed at stopping refluxing flow

Theoretical concept of a diastolic compression device is presented. The device could have a form of a pneumatic cuff or a rubber sleeve. Its objective is to exert external pressure below the knee, which would compress the great saphenous vein during the diastolic phase of the calf pump activity, and hinder thereby the saphenous reflux and the occurrence of ambulatory venous hypertension. Based on the results of venous pressure measurements, it is supposed that pressure of about 35 mm Hg would be able to fulfill this therapeutic aim. If tolerated and accepted by the patients, the device could offer, in addition to the current invasive methods and compression stocking therapy, a simple conservative, nonetheless effective treatment of primary varicose veins. It would keep the dividing line of the ambulatory pressure gradient below the knee, as is the case with healthy people, and prevent thereby the progression of the disease. In addition, this conservative method would preserve the great saphenous vein for possible use as a bypass graft in the future.
