Medical compression stocking may not be worn if the patient has the following conditions: Advanced peripheral arterial occlusive disease (if one of these parameters is present: ABPI < 0.5, ankle arterial pressure < 60 mmHg, toe pressure < 30mmHg or TcPO2 < 20 mmHg on dorsum of foot). When non-elastic materials are implemented, the patient can still try out compression stocking if they have ankle arterial pressure between 50 and 60 mmHg and they are under close clinical supervision. Decompensated heart failure (NYHA III + IV) Septic thrombophlebitis Phlegmasia cerulea dolens In the following instances, the therapeutic decision should be made by weighing up the benefits and risks and by selecting the most suitable compressive equipment: Severe weeping dermatosis Intolerance to compressive material Severe paraesthesia in the limbs Advanced peripheral neuropathy (e.g. in diabetes mellitus) Primary chronic polyarthritis If you are not sure whether one or more of these statements applies to you, speak to your doctor and/ or the medical personnel treating you.
