Introduction The department of interventional cardiology of Hopital Prive La Louviere describes the use of the DOSITRACE software for analyzing and optimizing radiation doses delivered to patients for five years. Methods 12874 procedures in the department of interventional cardiology with a Siemens Axiom Artis C-arm were collected with DOSITRACE software (from 2011 to 2016). Patient dose and examination parameters were recorded. The most common procedures are coronary angiography and coronary angiography without VG. The most radiative procedures are the coronary dilatation and CTO. Two alert levels are considered in function of risk. For weakly irradiating procedures: level 1 is twice the NRI (interventional Reference level), level 2 is four times the NRI. For highly irradiating procedures: level 1 is 300 Gy.cm2, level 2 is 600 Gy.cm2 (threshold at which deterministic effects would begin to appear). Alerts are studied over the five year evaluation period. Results The use of a DACS allows to reduce the interventional reference level. The NRI declined by 28.4% for the coronary angiography without VG and by 50.9% for the CTO. Conclusions This is the conclusion text. The use of DOSITRACE demonstrates decreased alerts, the dose optimization and risk reduction. |
