“…The DAP values for our patients were on average much larger than those reported by Geijer et al [16], but very similar to those reported by Weiss et al [17] and by Weerakkody et al [18]. The dosimetric parameters from our study and from three studies reported in the literature are compared in Table 1.…”

“…The median value (17 min) for time of procedure is, however, comparable to that in other studies [16][17][18]. As in some other studies [17,[22][23][24], we found a weak correlation (r 2 50.37) between DAP and fluoroscopy time.…”

“…To our knowledge, only limited data about the radiation dose burden of patients during aortic stent graft implantation have been published to date [16][17][18]. There are considerable differences in the threshold levels of deterministic effects between studies published by oncologists and radiologists, the levels reported in the oncology literature being higher [1,9,19].…”

ABSTRACT. Since the 1990s, stent graft implantation for aortic pathology has become an alternative to extensive surgical procedures in some patients. Indeed, many patients with such pathology are now treated endovascularly. Only limited data concerning the risk of a deterministic effect during aortic stent graft implantation are available. Accordingly, 179 consecutive patients treated in our institute between October 2002 and July 2008 with endovascular aortic stent grafts were included in this study. Dosimetric data (kerma area product (KAP) and cumulative dose at the interventional reference point (CD irp )) from radiograph reports were analysed for 172 patients. On a group of 19 patients, GAFCHROMIC XR type dosimetric films were also used to verify the automatic measurements. Readings from the integrated KAP meter were found to be too high and were therefore corrected -KAP to dose area product (DAP) and CD irp to entrance skin dose (ESD). Median DAP was 153 Gy cm 2 (35-700 Gy cm 2 ) and median ESD was 0.44 Gy (0.12-2.73 Gy). Recorded dosimetric quantities were found to be good predictors of the skin dose and highlighted 4 patients (2.3%) who received skin doses that might cause possible deterministic effects. Endovascular stent graft implantation is less invasive than a surgical procedure and is widely used; mid-term results are encouraging. In a small number of patients, deterministic effects can occur even in departments with well-trained staff. Operators should inform the patients of possible skin injury after receiving high doses of ionising radiation and proper support must be available should that occur.

“…Kuhelj, et al (2010) analyzing the dosimetric data on 179 patients treated using a suboptimal mobile C-arm unit found a 0.44 Gy median PSD (range 0.12 to 2.7 Gy). Investigators at Cabridge reported a 0.85 Gy median PSD on 96 repairs (Weerakkody, et al 2008;. About 1/4 of their patients received PSD higher than 3.75 Gy and the maximum dose was 8.8 Gy (the authors excluded from the analysis data on seven additional repairs because the "values were orders of magnitude greater than typical values recorded").…”
