“…While approximately the same percentage of men and women underwent EVAR for rAAA, women were usually less frequently treated endovascularly for nrAAA. The absolute values as well as the development over time are comparable with other countries (16,(29)(30)(31). In our opinion, the differences between the sexes for nrAAA are most likely due to distinct vascular anatomy, smaller access vessels, shorter landing zones for EVAR, and greater calcification of the vessel wall (32)(33)(34).…”

“…This study demonstrated stable eAAA repair rates, with an increase in the proportion of eEVARs from 9.6% in 2005 to 36.7% in 2009, and predicted that EVAR would account for at least 80% of all eAAA repairs by 2012. 34 Our findings confirmed the continued uptake of EVAR, but at a slower rate than predicted, presumably because of attenuation of midterm benefits. Jetty and Husereau are responsible for the only other study to investigate approach-specific AAA repair trends in Canada.…”

Objectives The uptake of endovascular aortic repair for elective and ruptured abdominal aortic aneurysm repair is not well studied. We aimed to examine the trends in open surgical repair and endovascular aortic repair of eAAA and rAAA and to examine the effects of randomized trial publications on elective open surgical repair and endovascular aortic repair rates. Methods We conducted a population-based time-series analysis of eAAA and rAAA repairs in Ontario, Canada from 2003 to 2016. We examined changes in overall and approach-specific rates of eAAA and rAAA repair using exponential smoothing models. Interventional autoregressive integrated moving average models were fit to the eAAA rates to examine the impact of randomized trial results on these rates. Results We identified 19,489 eAAA (12,232 open (63%) and 7257 endovascular (37%)) and 2732 rAAA (2466 open (90%) and 266 endovascular (10%)) repairs from 2003 to 2016. The rate of eAAA repair declined from 6.39/100,000 in 2003 to 5.59/100,000 in 2016 (13% decrease, p = 0.17). The rate of elective open surgical repair decreased nearly three-fold from 6.07/100,000 to 2.12/100,000 ( p < 0.0001), while elective endovascular aortic repair increased approximately 10-fold (0.32/100,000 to 3.47/100,000, p < 0.0001). The rate of ruptured open surgical repair decreased from 1.62/100,000 to 0.37/100,000 ( p < 0.44), while ruptured endovascular aortic repair uptake increased (0.00/100,000 to 0.12/100,000, p < 0.25). The mid-term results of the DREAM and EVAR-1 trials were associated with a decrease in the rate of elective open surgical repair decline after 2010 ( p = 0.01). Conclusions While elective open surgical repair use has significantly decreased from 2003 to 2016, elective endovascular aortic repair use has significantly increased. The DREAM and EVAR-1 results significantly impacted the observed rates of elective open surgical repair only. The reasons for these trends require further characterization.

“…This trend toward lower publication rates for open surgical topics may in part be explained by decreased interest both from key journals and surgeons in light of the dramatic increase in the use of endovascular techniques during the study time period. 16 We expected to see a higher publication rate following receipt of a CSVS research grant. Compared with either the CAGS Research Fund Grants or the SVS Seed Grants, which had publication rates of 88% and 66%, respectively, the CSVS research grants had a lower overall publication rate of 44%.…”

Background:The failure of investigators to publish research in peer-reviewed journals following acceptance at a national or international meeting can lead to significant publication biases in the literature. Our objective was to evaluate the abstract to manuscript conversion rate for abstracts presented at the Canadian Society for Vascular Surgery (CSVS) annual meeting and to evaluate the conversion rate for CSVS-awarded research grants. Methods:We searched for authors of abstracts accepted at the CSVS Annual Meeting (2007)(2008)(2009)(2010)(2011)(2012)(2013) and recipients of CSVS research awards (2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013) on Scopus and PubMed databases to identify related publications. Results:We identified 84 publications from 188 research abstracts (45%) and 17 publications from 39 research grants (44%). The mean time to publication was 1.8 years and the mean impact factor was 2.7. Studies related to endovascular therapies demonstrated a trend toward a higher rate of publication relative to open surgical therapies (64 [56%] v. 37 [27%]). Additionally, we observed a similar trend in research grant topics related to endovascular therapies relative to open surgical therapies (9 [67%] v. 8 [38%]). Finally, CSVS research grant recipients who subsequently published had a significantly higher h-index at the time of receipt than those who had not published. Conclusion:The CSVS annual meeting's abstract to publication conversion rate is comparable to that of its Canadian peers as well as to other medical specialties; however, a substantial publication gap remains. We identified several potential areas that may help to improve the effectiveness of CSVS research grants.
