Operator vs. patient radiation exposure in transradial and transfemoral coronary interventions

Transradial arterial access for coronary and peripheral procedures: Executive summary by the transradial committee of the SCAI

“…Radiation exposure decreases as the operator advances along the TRA learning curve. Absolute increases in fluoroscopy time and dose area product with TRA compared to TFA are small, likely representing minimal risk to the patient (0.002% increase in lifetime cancer risk), and must be balanced against the benefits of decreased access site complications and bleeding [133, 134].…”

“…Secondly, the level of physician and patient adherence to guideline-based inpatient and outpatient therapies was not recorded. Thirdly, the present analyses pertain only to trans-femoral access, however previous literature has produced contradictory results on differences in radiation exposure from procedures performed via femoral versus radial access [2,3,[5][6][7][8][9]. Finally, the level of fellow involvement during the PCI procedure was not recorded, although prior studies have demonstrated that fellow-performed procedures were not independently associated with higher radiation dose [2].…”

“…However, most of these data have focused on access route (femoral versus radial) and elective versus non-emergent procedures [2,3,[5][6][7][8][9]. Moreover, no studies to date have examined whether there is a relationship between elevated radiation dose and clinical outcomes.…”

Radiation exposure of operator during coronary angiography and coronary intervention: comparison of left radial and femoral accesses

“…Dávka pod stínicí zástěrou je i u prvního katetrizujícího neměřitelná 22. U většiny výkonů je tedy dávka záření u pacienta i katetrizujícího i u RA zanedbatelná a je výrazně převážena celkovým přínosem při nepřítomnosti krvácivých komplikací 27. V naší práce se při FA, zvlášť u SKG, dávky pohybovaly na hranici měřitelnosti.…”
