Comparison of radiological exposure of patients undergoing coronary angiography and staged or ad hoc percutaneous coronary intervention by radial access
DOI: 10.31160/JOTCI201927A201814
ABSTRACT
Background
Ad hoc percutaneous coronary intervention via radial access has become frequent in interventional cardiology services, with reduced bleeding rates, vascular complications and costs. There are few reports in the medical literature on radiological exposure rates (kerma area product − Kap, and incident air kerma − Iak) in these procedures, when they are performed via radial access. The objective of the study was to compare radiological variables in staged percutaneous coronary interventions with ad hoc interventions via radial access.
Methods
A total of 120 patients were studied, divided into two groups of 60: Group A, patients undergoing diagnostic coronary angiography and staged percutaneous coronary intervention, versus Group B, patients undergoing ad hoc percutaneous coronary intervention via radial access, from August 2014 to September 2015. The values of radiological exposure rates were measured.
Results
When comparing Groups A and B, we observed body mass index of 27.83±4.20kg/m2 vs. 26.88±4.14kg/m2 (p=0.3); total Kap of 16,222.5±10,613.5µGym2 vs. 12,029.2±7,360.6µGym2 (p=0.01); total Iak of 3,886.8±2,946.7mGy vs. 2,940.3±1,841.0mGy (p=0.04); total fluoroscopy time of 23.2±13.17 minutes vs. 17.1±9.68 minutes (p=0.0009); SYNTAX score 14.7±8.3 vs. 13.7±8.9 (p=0.54).
Conclusion
Radiological exposure rates in ad hoc percutaneous coronary interventions were lower than in staged percutaneous coronary interventions, when the procedures are performed via radial access.
