[Experience With Different Single-Stage Selective Arterial Catheterization Procedures During X-Ray Endovascular...

Area of Science:

• Medical Imaging
• Interventional Radiology
• Radiation Oncology

Background:

• X-ray endovascular interventions are crucial for treating conditions like coronary heart disease and uterine myomas.
• Minimizing radiation exposure to patients during these procedures is a significant clinical challenge.
• Previous methods may not have optimized radiation dose reduction strategies.

Purpose of the Study:

• To evaluate the impact of single-stage selective arterial catheterizations on patient radiation doses.
• To assess the effectiveness of this technique in reducing collective effective radiation doses during X-ray endovascular interventions.
• To analyze dose reduction trends over time (2013-2015).

Main Methods:

• Utilized a flat detector digital angiography system (Siemens Axiom Artis dTA).
• Analyzed data from endovascular interventions for coronary heart disease and uterine myomas.
• Focused on single-stage selective arterial catheterization procedures.

Main Results:

• Single-stage selective coronary angiography and uterine artery embolization techniques were employed.
• Collective effective patient radiation doses decreased from 5.86 persons-Sv in 2013 to 1.6 persons-Sv in 2015.
• Demonstrated a substantial reduction in radiation exposure through optimized catheterization.

Conclusions:

• Single-stage selective catheterization is an effective strategy for reducing radiation doses in endovascular interventions.
• The findings support the widespread adoption of these techniques to enhance patient safety.
• Further research may explore other applications of this dose-reduction methodology.
