“…Our claim of a real-world, nationwide representation is substantiated by the results of our calculated mean total cost, which is consistent with the results of the National In-patient Sample, 32,37 24,38 Our cost data are synchronous with index hospital admission data of American studies. 31,32,38,39 Interestingly, our results also contrast Brazilian, 26 Korean, 40 and Japanese 41 studies that suggest EVAR is costlier than OAR, which is probably owing to countrywise differences 42 in procedural application and cost of hospital stay. 20 Similar to any retrospective administrative database study, our study had several limitations, including erroneous coding or improper data entry, leading to systemic bias.…”

Background: Endovascular aneurysm repair (EVAR) has become the preferred strategy for elective repair of abdominal aortic aneurysm (AAA) for many patients. However, the superiority of the endovascular procedure has recently been challenged by reports of impaired long-term survival in patients who underwent EVAR. A systematic review of long-term survival following AAA repair was therefore undertaken.Methods: A systematic review was performed according to PRISMA guidelines. Articles reporting shortand/or long-term mortality of EVAR and open surgical repair (OSR) of AAA were identified. Pooled overall survival estimates (hazard ratios (HRs) with corresponding 95 per cent c.i. for EVAR versus OSR) were calculated using a random-effects model. Possible confounding owing to age differences between patients receiving EVAR or OSR was addressed by estimating relative survival.Results: Some 53 studies were identified. The 30-day mortality rate was lower for EVAR compared with OSR: 1⋅16 (95 per cent c.i. 0⋅92 to 1⋅39) versus 3⋅27 (2⋅71 to 3⋅83) per cent. Long-term survival rates were similar for EVAR versus OSR (HRs 1⋅01, 1⋅00 and 0⋅98 for 3, 5 and 10 years respectively; P = 0⋅721, P = 0⋅912 and P = 0⋅777). Correction of age inequality by means of relative survival analysis showed equal long-term survival: 0⋅94, 0⋅91 and 0⋅76 at 3, 5 and 10 years for EVAR, and 0⋅96, 0⋅91 and 0⋅76 respectively for OSR.Conclusion: Long-term overall survival rates were similar for EVAR and OSR. Available data do not allow extension beyond the 10-year survival window or analysis of specific subgroups. Literature search and inclusion criteriaA systematic review of the literature between 1991 and 2018 was undertaken according to PRISMA guidelines 6 . Studies were identified using PubMed, Embase, Web of Science and Cochrane databases. Eligible studies included patients with an intact AAA treated by either EVAR or OSR. Studies that did not compare Publication biasFunnel plots for 30-day and 5-year survival did not show considerable asymmetry (Fig. S2, supporting information).

“…On the contrary, the EVAR technique became the preferred method for uAAAs since 2008, consistent with the literature [16] . The advantage of this surgical procedure is that it requires shorter hospitalizations (on average 5 days less), although it is more costly [15] , [36] . However, the adjusted mortality did not decrease since the adoption of EVAR technique, in line with Gupta et al [37] that used prospectively collected data from the National Surgical Quality Improvement Programme (for patients <60 years).…”

BackgroundRecent studies have reported declines in incidence, prevalence and mortality for abdominal aortic aneurysms (AAAs) in various countries, but evidence from Mediterranean countries is lacking. The aim of this study is to examine the trend of hospitalization and post-operative mortality rates for AAAs in Italy during the period 2000–2011, taking into account the introduction of endovascular aneurysm repair (EVAR) in 1990s.MethodsThis retrospective cohort study was carried out in Emilia-Romagna, an Italian region with 4.5 million inhabitants. A total of 19,673 patients hospitalized for AAAs between 2000 and 2011, were identified from the hospital discharge records (HDR) database. Hospitalization rates, percentage of OSR and EVAR and 30-day mortality rates were calculated for unruptured (uAAAs) and ruptured AAAs (rAAAs).ResultsAdjusted hospitalization rates decreased on average by 2.9% per year for uAAAs and 3.2% for rAAAs (p<0.001). The temporal trend of 30-day mortality rates remained stable for both groups. The percentage of EVAR for uAAAs increased significantly from 2006 to 2011 (42.7 versus 60.9% respectively, mean change of 3.9% per year, p<0.001). No significant difference in mortality was found between OSR and EVAR for uAAAs and rAAAs.ConclusionsThe incidence and trend of hospitalization rates for rAAAs and uAAAs decreased significantly in the last decade, while 30-day mortality rates in operated patients remained stable. OSR continued to be the most common surgery in rAAAs, although the gap between OSR and EVAR recently declined. The EVAR technique became the preferred surgery for uAAAs since 2008.
