Abstract

A 48-year-old woman attended to discuss a dilemma. She had suffered a cardiac arrest immediately following microsclerotherapy of leg telangiectasia with 0.3% aethoxysklerol. She had successful defibrillation and been transferred to hospital. In hospital, despite normal cardiac tests, she was diagnosed as having idiopathic cardiac arrest. The exposure to aethoxysklerol was discounted by her cardiologists as a cause of her arrest. Following the hospital protocol, she was strongly advised to have an implantable defibrillator. Cardiac arrest and myocardial infarction are documented after aethoxysklerol injection with proposed mechanisms being anaphylaxis, direct cardiotoxicity or endothelin-1 release. Before consenting to an implantable defibrillator, which may have its own complications in the long term, doctors and the patient need to be certain that this arrest was not due to a reaction to aethoxysklerol.

Keywords: Cardiac arrest; aethoxysklerol; anaphylaxis; sclerotherapy.
