EXPERIENCE WITH DIFFERENT SINGLE-STAGE SELECTIVE ARTERIAL CATHETERIZATION PROCEDURES DURING X-RAY ENDOVASCULAR INTERVENTIONS TO REDUCE A RADIATION DOSE FOR PATIENTS

Objective: to evaluate the impact of single-stage selective arterial catheterizations during X-ray endovascular interventions to reduce obtained radiation doses in the treatment of patients. Material and methods. X-ray endovascular interventions were carried out in the operating room equipped with a flat detector digital angiography system (Axiom Artis dTA, Siemens Medical System). The impact of single-stage selective arterial catheterization procedures was analyzed during endovascular interventions for coronary heart disease and uterine myomas on the time course of changes in the collective effective radiation doses for patients in the period 2013 to 2015. Results. Analysis of the findings showed that single-stage selective coronary angiography using a universal (multipurpose) radial coronary catheter and single-stage X-ray endovascular uterine artery embolization techniques could reduce collective effective doses for patients from 5.86 persons-Sv in 2013 to 1.6 persons-Sv in 2015. Conclusion. Different single-stage selective catheterization procedures used during endovascular interventions into the coronary and uterine arteries can reduce radiation doses for patients.
