Abstract

The purpose of this study was to estimate both patient and staff radiation doses during coronary angiography and percutaneous transluminal coronary angioplasty with stenting procedures by direct measurement and to compare these results with data from the literatures. Radiation doses from 159 patients have been studied, 101 of which had undergone coronary angioplasty and 58 percutaneous transluminal coronary angioplasty with stenting. All procedures were undertaken on biplane angiocardiographic system (Phillips Integris). The system performed under automatic exposure control using continuous fluoroscopy and cine frame rate of 12.5 frames s-1. Dose-area product values and fluoroscopy times were collected for each patient. Median values for dose—area product were 39.3 Gy cm2 for coronary angiography and 146.7 Gy cm2 for percutaneous transluminal coronary angioplasty with stenting. Median fluoroscopy time was 3.8 min and 17.7 min for coronary angiography and percutaneous transluminal coronary angioplasty with stenting, respectively. Comparison showed that patient dose-area product values for coronary angiography were lower than other studies and fluoroscopy time values were comparable. But the patient dose-area product values and fluoroscpy time for percutaneous transluminal coronary angioplasty with stenting were higher than other studies. The cardiologist received a median dose of 253.9 uGy and 264.5 uGy to the lens of the eye, and 261.3 uGy and 256.5 uGy to the skin level of thyroid, per procedure of coronary angiography and percutaneous transluminal coronary angioplasty with stenting respectively. Recommendations for optimization of patient doses are given.
