Abstract:
Objective :To obtain the peak skin dose (PSD) of patients with interventional cardiology procedures and toevaluate the risk of deterministic effects.
Methods : Gafchromic XR RV3 films were used in a Level A tertiary hospital inBeijing to measure the PSD of patients who underwent interventional cardiology procedures. The measurement focused onfour common types of procedures, including coronary angiography, percutaneous transluminal coronary angioplasty,cathet-er radiofrequency ablation, and congenital heart disease. The films were scanned by EPSON EXPRESSION 10000XL andanalyzed by FILM QA ProTM 2014 software.
Results :PSD was measured in 59 patients with interventional cardiologypro-cedures, including 23 with coronary angiography, 21 with percutaneous transluminal coronary angioplasty, 9 with catheterradiofrequency ablation, and 6 with congenital heart disease. The seven patients with PSD ≥ 2 Gy all underwentpercu-taneous transluminal coronary angioplasty, one with PSD > 3 Gy and six with PSD < 2 Gy.
Conclusion : The PSD of somepatients with interventional cardiology surgery exceeded the dose threshold of deterministic effects recommended by theICRP 118. There is a risk of deterministic effects in interventional cardiology surgery, especially in patients withpercu-taneous transluminal coronary angioplasty.
