Abstract
Objective:Cardiovascular interventional therapy for children Statistics and Analysis of X-ray radiation dose to explore low-dose technology in the protection of children. Methods:The hospital nearly two years the use of low-dose technology in the interventional diagnosis and treatment of children, a retrospective analysis of 18 patients under the age of three kinds of treated me institutes common childhood intervention operations radiation levels were nearly two years and two years ago the same operation of the radiation levels in patients with technical analysis, a total of 300 cases. Among them, 60 cases of atrial septal defect occlusion in patients with ventricular septal defect occlusion in patients with 90 cases, patent ductus arteriosus occlusion in patients with 150 cases. Using digital subtraction angiography machine automatically adjusts the exposure conditions. Including entrance dose ED(mGy), dose area product DAP and fluoroscopy time F were measured. Results:The two groups results in the perspective of time, entrance dose, there was a significant difference, nearly 2 years statistics show a significant reduction in radiation dose in children suffered, both between entrance dose and fluoroscopy time was significantly a linear relationship. Area of operation of different doses of the product of cardiovascular intervention there was a significant difference, ventricular septal defect occlusion area dose product is still large. Conclusion:Low-dose technology effectively reduces the radiation dose for children, worthy of promotion.关键词
