Venous reflux is when blood flows in a vein in the opposite than normal direction or away from the heart towards the legs due to gravity. Venous blood flow is not continuous, but blood can be lifted from the legs toward the heart due to compression of the deeper veins that travel through the muscles. There are also one-way valves in the veins to prevent reflux when the muscle relaxes. A vein specialist can treat venous reflux and varicose veins as minimally invasive office procedures. Finally, venous reflux is not normal and is best determined and graded by an ultrasound examination.
Without all your history it is a little difficult to answer. 10 years ago the cardiac surgeons were using long saphenous veins as well as arteries to heart graft. If they did not take yours (perhaps they were refluxing back then also) it is possible you still have venous reflux. This should be diagnosed by ultrasound examination in the standing position. If present, this is easily treated in the office under local anesthetic with little or no downtime using laser. Physical rehab will not correct reflux and reflux is not normal.
