This is an abbreviation for Graduated Elastic Compression stockings. They are the universal conservative treatment option for the majority of venous disorders. They are usually knee length or thigh length. They are made in several compression strengths measured at the gaiter area which is just above the ankle joint. The lowest compression starts at a class 1 (18-21 mmHg), then a class 2 (23-32 mmHg) followed by a class 3 (34-46 mmHg). Current research is directed at customising stockings for patients. This is because legs are of various different shapes and because some strengths and lengths are more effective at reducing reflux and promoting the venous return.
