Radiation-Induced Skin Injury after Percutaneous Transluminal Coronary Angioplasty

Abstract

A 58-year-old man underwent percutaneous transluminal coronary angioplasties in June 1992 and May 1993. Approximately 3 weeks after the last procedure, a cutaneous lesion developed into an ulcer over the right scapular region. The ulcer failed to heal with conservative treatment; therefore, surgical excision was performed. The localization and the course of the development indicated injury caused by radiation, and this was confirmed by the histologic examination. To avoid such injury in interventional procedures with long fluoroscopic time, several precautions should be taken. These include continuous surveillance of the X-ray dosage, the use of different projections to avoid exposure to one skin area throughout the whole procedure, keeping the irradiated area as small as possible, and good planning of the procedure.
