Purpose. To assess the ability of a color graphic system for monitoring the radiation dose in real time to influence the peak dose in the patient's skin and the total radiation dose during X-ray endovascular interventions.

Materials and methods. In the course of the study, the indicators of peak skin dose, fluoroscopy time and radiography time were compared when performing interventional interventions using a color graphical system for monitoring the radiation dose in real time, as well as without using the specified functionality. In total, 295 patients were successively subjected to various endovascular interventions, of which 83 underwent PCI, 8 balloon angioplasty of the lower extremity arteries, 22 angiography of brachiocephalic arteries, 5 cava filter installation. The patient's anthropometric data, the type of intervention, radiation parameters, frame rate and the number of episodes were recorded.

Results. Statistical analysis showed that the introduction of a real-time skin dose recording system resulted in a 17.9% reduction in the peak skin dose. The reduction in radiation dose was most pronounced in patients with PCI, but was also observed in a number of subgroups with high BMI. It is reliably established that after the introduction of real-time radiation monitoring, in addition to reducing the peak dose in the skin, there is also a decrease in the total time of exposure to ionizing radiation on the patient.

Conclusions. The installation of a special integrated dose tracking system in real time reduced the absorbed dose in the patient's skin and the total exposure time during interventional interventions. This allows us to consider this technology as an effective tool for ensuring radiation safety.
