Measurement and Optimization of Patient Radiation Doses in Endovascular Aneurysm Repair

Measurement and Optimization of Patient Radiation Doses in Endovascular Aneurysm Repair

Abstract The study assessed radiation exposure during EVAR. Two types of patient dose were estimated: effective dose (ED), which allows estimation of radiation risk to the EVAR patient population; and Peak Skin Dose (PSD), which allows us assess the potential for an individual patient to receive a r...

Zusammenfassung:Abstract The study assessed radiation exposure during EVAR. Two types of patient dose were estimated: effective dose (ED), which allows estimation of radiation risk to the EVAR patient population; and Peak Skin Dose (PSD), which allows us assess the potential for an individual patient to receive a radiation skin injury. An ancillary aim was to examine dose optimization in EVAR procedures. Based on 111 EVAR cases we estimated average ED as 12.4 mSv. Cumulative patient dose in our centre was lower than other studies because the follow up of EVAR patients is based on ultrasound rather than CT. PSD calculated using a published conversion formula closely matched measurements with calibrated gafchromic film. 99% of patients had an estimated PSD of
