Off-label use in the case of tumescent local anaesthesia for endovascular and operative procedures

Tumescent local anaesthesia (TLA)has increasingly established itself as the anaesthesia method for operations on varicose veins and has become the standard method in the case of endovascular techniques. However, Off-label use occurs due to the reduced concentration of the local anaesthetic, the incorporation of additives together with a high quantity of LA which exceed the manufacturer’s recommended maximum dosage. In spite of a lack of significant complications arising from the approved use of the TLA and unambiguous positive evaluations of this anaesthesia method by international medical professional associations, the operating phlebologist should inform the patient of this off-label use both in the case of operative procedures and endovascular techniques in order to avoid any legal problems.
