Dosimetric determination of radiation exposure of patients and personnel during diagnostic and interventional endovascular procedures at the DSA department of UVN, recovery plan for a potential extraordinary event

Intervention radiology is a discipline that is achieving a great advancement due to its significant success in the treatment of various diseases. Also, it relates to the increase of the number of angiographic performances in the last years. The extension of radiological methods has increased the share of this discipline on the overall medical irradiation of the population. All angiographic performances are accompanied by certain risk related to the exposure of the patient and staff to the ionizing radiation. Several cases were reported where the surface doses were reaching the limits of deterministic effects of radiation in some types of examination. This study monitors three core criteria related to the radiation burden in the set of 141 patients, which have undertaken different endovascular interventions. These criteria are: the dose area product (DAP), surface dose, and effective dosage. The relevant criterion was the value of DAP, read from the DAP meter directly during the examination. Other data were calculated. On basis of these results, this study tries to determine the strenuousness of singular examinations from the point of the radiation burden. It is the understanding the principles of the influencing the patient{\crq}s burden of the radiation in angiographic examinations, what can help in reducing the dosages. The analysis of this study results can help to prevent the occurrence of abnormal events during the examination
