[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.

[The experience of using magnetic resonance imaging of the uterus and its appendages as an alternative to X-ray hysterosalpingography].

Objective: Determination of the diagnostic capabilities of magnetic resonance imaging of the uterus and its appendages (MRHSG) on devices with the induction of the magnetic field 3 Tesla (T) as an alternative to the classic X-ray hysterosalpingography, accompanied by a significant radiation dose to the patient. Material and Methods: During the period from April 2015 to February 2016 12 MRHSG was conducted using magnetic resonance imaging apparatus Verio Magnetom 3T, Siemens company (Diagnostic Center "BarsMed", Kazan, Russia). We used neutral and not giving adverse reactions contrast agent ­ carbon dioxide. The pelvic organs ­ the uterus and fallopian tubes ­ represent the zone of interest. Results: Analysis of the data showed that MRHSG on the apparatus with the induction of the magnetic field of 3 T is a highly informative method in the diagnosis of tubal patency, allowing fully assess the state of the pelvic organs on the whole and identify pathology. The absence of radiation exposure and contraindications associated with intolerance to iodinated contrast agents and other side effects differs MRHSG from the traditional X-ray method and makes MRHSG to be an alternative secure method of diagnosis, which has a number of advantages described in the article. Conclusions: MRHSG on the apparatus with the induction of the magnetic field of 3 T in diagnosis of obstruction of the fallopian tubes and the visualization of the uterus and appendages diseases can be optimal and safe alternative to the X-ray hysterosalpingography, which accompanied with radiation exposure and is a number of side effects.
