The Effects of Gender on Radiation Dose During Fenestrated Endovascular Aneurysm Repair.

Abstract Introduction Female gender is considered a risk factor for worse perioperative outcomes following Fenestrated Endovascular Aneurysm repair (FEVAR). We hypothesized that women would have more unfavorable anatomy, increasing case complexity and leading to higher radiation doses. Our aim was to evaluate the effect of gender on radiation dose during FEVARs. Methods This single-center retrospective study was performed from 1/2015-2/2018. For patient data, linear model and stepwise variable selection algorithm were used. All dose measurements were log-transformed before analysis. Significance level for parameter estimates and corresponding 95% confidence intervals were all transformed back using an exponential function. P-value of Results 169 FEVARs (45 women) were performed on a Philips Allura Xper FD 20 fluoroscopy system equipped with clarity technology. There was no difference in BMI or operative time between genders, p=0.9. The median RAK for women was significantly lower compared to men (1672 mGy vs. 2496 mGy), p Conclusion FEVARs can be performed successfully in women with comparatively lower radiation doses.
