Abstract:
Pseudoaneurysms of peripheral arteries are not an uncommon condition presenting to vascular surgeons. Perioperative injury and infection are two of the commonest causes. We describe a case of an 82-year-old lady, who presented 10 years following right shoulder joint replacement, with a sharply marginated erythematous cutaneous eruption over the right shoulder. Subsequent angiography revealed a pseudoaneurysm of the acromial branch of the thoracoacromial artery. Planned intervention was superseded by a further embolic episode, which prompted immediate percutaneous translumninal embolisation of the aneurysm. The aetiology of a pseudoaneurysm 10 years following shoulder arthroplasty is discussed.
