Abstract
Reduction in X-ray exposure during cardiac catheterization is important to reduce radiation risks to operators and personnel. Reducing scattered radiation from the patient can achieve this goal. The goal of this study was to evaluate the reduction in radiation using simple partial shielding of patients undergoing cardiac catheterization. By putting a lead-based apron on the lower extremities of patients undergoing cardiac catheterization, we analyzed the reduction in total radiation dose with and without this shielding. One hundred and twelve patients were divided into two groups. In one group, the protective lead-based apron was put on the lower extremities of patients. Another group did not have any shielding. Total duration of angiography was 332 minutes and 45 seconds in the first group and 269 minutes and 10 seconds in the second group. The total radiation exposure was 33 μGy in the first group vs 606 μGy in the second group. Despite higher exposure time, total radiation dose was 22 times lower in the simple shielded group. Our simple method without any additional cost can significantly reduce radiation exposure in the cardiac catheterization laboratory.
Highlights
IntroductionSince introducing x-ray for medical proposes, protective strategies had developed for more safety, for patients and for operators
A total of 240 minutes and 25 seconds of cine-angiography were performed in patients undergoing angiography (68 patients) in comparison to 361 minutes and 30 seconds for patients undergoing percutaneous coronary intervention (44 patient)
The risks posed by radiation exposure in the cardiac catheterization laboratory are underestimated by interventional cardiologists with growing concern [1]
Summary
Since introducing x-ray for medical proposes, protective strategies had developed for more safety, for patients and for operators. Many protocols were introduced to reduce radiation exposure. Scattered tradition is one of the major causes of radiation exposure. Definition of scatter radiation in the USA national cancer institute (NCI). Is the radiation that spreads out in different directions from a radiation beam when the beam interacts with a substance, such as body tissue for example the patients’ body surface. There are some factors affecting quantity of scatter radiation such as volume of tissue, density of matter, field size and kilo voltage
