Abstract Relationship between radiation-induced skin ulceration (RSU) and variables in percutaneous coronary interventions (PCI) was rarely reported. RSU is a severe complication in PCIs, especially for chronic total occlusion (CTO) lesions. We investigated the RSUs and their risk factors in patients receiving CTO PCIs over a 2-year period. Data were analyzed using chi-square tests, t-tests and receiver operating characteristic (ROC) curve. Of 238 patients, 11 patients (4.6%) had RSUs all at right upper back. RSUs were significantly associated with use of left anterior oblique (LAO) views (100% vs. 47.1%, p 120, 180, or 240 minutes (p < 0.05). ROC analysis showed a long PT was an accurate predictor of RSUs (AUC = 0.88; p < 0.001) at a cut-off of 130 minutes (sensitivity = 0.91, specificity = 0.81). The results showed risk factors for RSUs containing use of large LAO views, retrograde techniques, and prolonged PTs. This study suggests that, to minimize RSU, interventionalists should limit PT to roughly 2 hours in fixed LAO views.
