Evaluation of Radiation during EVAR Performed on a Mobile C-arm

Abstract

Indirect DAP values measured by the C-arm are accurate to evaluate radiation exposure. Compared to the literature, our values for standard procedures are significantly decreased by the usage of low dose and pulse mode. DAP for fenestrated and branched procedures was comparable to published DAP values with standard procedures using a regular fluoroscopic mode.

Radiation Induced DNA Damage in Operators Performing Endovascular Aortic Repair

“…We and other groups have previously reported that DAP, fluoroscopy, and radiation exposure is higher for these complex procedures compared with standard IEVAR. 4,33 In our experience, BEVAR/FEVAR was associated with a 2-fold increase in DAP and 3-fold longer fluoroscopy time. 5 The present study confirmed, by personal dosimetery, an ≈2-fold higher exposure at leg level for the operator performing BEVAR/FEVAR as opposed to IEVAR.…”

“…1,2 The growing number and complexity of procedures means that interventionists are exposed to higher amounts of radiation, a subject that is becoming increasingly topical. [3][4][5][6][7] A recently published 15-year follow-up study of the EVAR trial, comparing endovascular and open aortic repair, reported an increased incidence of malignancy in patients treated by EVAR. 8 There is, rightly so, a significant focus currently on reducing the patients' exposure to radiation, but mounting evidence suggests that recurrent lowdose exposure to the practitioner is equally as important.…”

CTA with Fluoroscopy Image Fusion Guidance in Endovascular Complex Aortic Aneurysm Repair

“…The total DAP of fenestrated and branched endovascular aneurysm repair procedures has been described in the range of 1e78 mGym 2 . 9 The case control pairs were not matched for body characteristics. Procedural DAP is influenced by patients' body mass index and further non-comparable between all procedures due to a software update of our hybrid fluoroscopy unit intended to shift radiation dose to a lower level.…”

Radiation Dose Reduction During EVAR: Results from a Prospective Multicentre Study (The REVAR Study)

“…In 2012, one centre from this study published its dose reports during standard EVAR with a mobile C-arm and a strict compliance with the ALARA principle. 17 The median DAP was around 30 Gy$cm 2 . Two years later, the same team published the results of a similar cohort, but with cases performed in a modern hybrid room with features designed to reduce radiation and fusion imaging support.…”
