Thoracoabdominal Aortic Aneurysm Repair Using Fenestrated and Branched Endovascular Grafts for High-Risk Patients: Evolving yet Safe.

PURPOSE: The purpose was to investigate outcomes of high-risk patients undergoing thoracoabdominal aortic aneurysm (TAAA) repair using fenestrated or branched endovascular aneurysm repair (F/BEVAR) devices at a single center in Canada. MATERIALS AND METHODS: A retrospective review of all patients undergoing endovascular TAAA repair with F/BEVAR from June 2007 to July 2020. Imaging and clinical endpoints of interest including death, reintervention, and target vessel patency were reported. RESULTS: Ninety-five consecutive patients underwent endovascular TAAA repair using F/BEVAR stent grafts (63 males, median age 74 [interquartile range 70, 78] years). Repairs included 81 elective and 14 urgent/emergent cases (6 ruptures and 8 symptomatic). Graft deployment was 100% successful. Intraoperative target vessel revascularization was successful in 336/355 (94.6%) vessels with the celiac having the lowest success rate 72/82 (87.8%). In-hospital mortality was 9.5% (7.4% elective and 21.4% urgent/emergent, p=0.125) and permanent paraplegia was 4.2% (3.7% elective and 7.1% urgent/emergent, p=0.458). In-hospital complications included stroke in 5.3%, acute myocardial infarction in 8.4%, and bowel ischemia in 5.3%. No patients required permanent dialysis or tracheostomy during their hospital stay. However, 22 (23.2%) patients required additional unplanned procedures for various indications (branch occlusion, endoleaks, realignment) during their hospital stay. Patients were followed up for a mean of 3.6 ± 3.0 years. Clinical follow-up was 100%, with 80/86 (93%) having surveillance imaging. On follow-up imaging, 43 (50%) patients had at least 1 endoleak identified and 337/341 (98.8%) of the target vessels were found to be patent. At 5 years, cumulative probability of reintervention was 46.3% (95% confidence interval [CI], 36.1-56.4). Survival at 5 and 8 years was 50.1% (95% CI, 38.4-65.4) and 34.4% (95% CI, 22.5-52.8), respectively. Progression of aneurysmal disease leading to rupture on follow-up was confirmed in 1 patient at 10 years. CONCLUSION: Endovascular TAAA repair provides a safe treatment option with a high technical success rate and low pulmonary and renal complications. Long-term survival is similar to previous literature; however, high rates of secondary reintervention reaffirm the need for ongoing patient follow-up and further technical improvements. CLINICAL IMPACT: This study demonstrates that endovascular repair of TAAAs can be performed in a high-risk elderly population with acceptable rates of mortality, TALE and SCI, using evolving technology. The incidences of post-operative respiratory failure and renal dysfunction were lower in patients who underwent endovascular repair compared with open repair. Future technical and procedural refinements in addition to increasing surgical experience are expected to lead to further improvements in short- and long-term outcomes exceeding those of open repair.

Outcomes in octogenarians after thoracoabdominal and juxtarenal aortic aneurysm repair using fenestrated-branched devices justifies treatment.

OBJECTIVE: To compare outcomes between octogenarians and nonoctogenarians undergoing thoracoabdominal aortic aneurysm repair and juxtarenal aortic aneurysm repair using branched and/or fenestrated endovascular devices (F/BEVAR) and compare octogenarian survival to population survival statistics from Ontario, Canada. METHODS: Patients who underwent F/BEVAR at a single institution between 2007 and 2020 were retrospectively reviewed with a median follow-up of 3.3 years (interquartile range, 1.6-5.3). The median survival of an average 84-year-old Ontarian from Canada, adjusted for a male:female ratio of 4:1, was retrieved from publicly available Statistics Canada data. RESULTS: In total, 68 octogenarians (25.8%) and 196 nonoctogenarians (74.2%) were included (mean age, 83.5 ± 3.0 vs 71.9 ± 5.8 years; P ≤ .001). The maximum aneurysm size was significantly larger in octogenarians (68.9 ± 11.4 mm vs 65.4 ± 10.0 mm; P = .017). No differences in the number of thoracoabdominal aortic aneurysm repairs (29.4% vs 38.3%; P = .19) or operative technical success (92.6% vs 85.7%; P = .136) were observed between the two cohorts. Postoperatively, no significant differences in overall in-hospital mortality (7.3% vs 5.1%; P = .49), elective in-hospital mortality (6.1% vs 4.4%; P = .49), stroke (1.5% vs 3.6%; P = .384), or spinal cord ischemia (2.9% vs 9.2%; P = .094) were seen between octogenarians and nonoctogenarians. There was no difference in survival at 4 years between the two cohorts (62.9% vs 71.1%; P = .22), however, survival at 6 years was significantly lower for octogenarians (44.5% vs 64.1%; hazard ratio, 1.96; P = .02). The cumulative rate of reintervention (44.1% vs 41.3%; P = .84) and freedom from branch instability (67.6% vs 73.5%; P = .33) at 6 years were not different between the two groups. When comparing octogenarians who survived to discharge from index hospitalization after F/BEVAR with 84-year-old Ontarians unmatched for comorbidities, a survival difference of 4.8% and 11.1% was noted at 4 and 6 years, respectively. CONCLUSIONS: F/BEVAR in octogenarians is associated with no differences in technical success or postoperative adverse outcomes when compared with their younger counterparts. Octogenarians had increased mortality after 4 years and their survival at 4 years was comparable with that of an 84-year-old Ontarian. F/BEVAR was safe and effective in octogenarians deemed fit for intervention. Further research into preoperative patient selection and improving perioperative outcomes is needed.

Females experience elevated early morbidity and mortality but similar midterm survival compared to males after branched/fenestrated endovascular aortic aneurysm repair.

OBJECTIVE: The objective of this study was to identify sex-related differences in outcomes following branched and/or fenestrated endovascular aortic repair (B/FEVAR) for thoracoabdominal (TAAA) and juxtarenal (JRAA) aortic aneurysms. METHODS: Chart review completed on 242 B/FEVAR patients (57 female; 23.5%) between 2007 and 2020 at a single center. Median follow-up time was 3.3 years (interquartile range [IQR], 1.6-5.3 years). RESULTS: No statistically significant differences in age (females, 75.9 ± 5.4 years vs males, 74.7 ± 7.2 years; P = .162) or aneurysm size (64.9 ± 6.8 vs 65.8 ± 9.4 mm; P = .41) at presentation were observed between sexes. Females presented with fewer JRAAs (45.6% vs 73%; P < .001) and received more Crawford extent II (26.3% vs 10.8%; P =.004) TAAA coverage. Increased incidence of moderate/severe target vessel stenosis (29.8% vs 14%; P = .022) was observed in female patients. Intraoperatively, females had higher procedure times (530 [IQR, 425-625] vs 420 [IQR, 350-510] minutes; P < .001), fluoroscopy times (124.1 ± 49 vs 107.3 ± 43.5 minutes; P = .017), and contrast usage (200 [IQR, 150-270] vs 175 [IQR, 130-225] mL; P = .005). Unplanned intraoperative maneuvers (45.6% vs 28.1%; P = .043), graft delivery issues (24.6% vs 4.9%; P < .001), and additional intraoperative complications (61.4% vs 35.7%; P < .001) were also increased in females. Postoperatively, females had a longer intensive care unit (3 [IQR, 1-5] vs 1 [IQR, 1-3] days; P = .002) and hospital stay (8 [IQR, 5-13] vs 5 [IQR, 3-9] days; P < .001) and experienced increased rates of spinal cord ischemia (15.8% vs 3.8%; P = .001) and bowel ischemia (10.5% vs 2.7%; P = .013). In-hospital mortality (12.3% vs 2.7%; P = .004) was higher in female patients but midterm (6-year) survival was 60.2% for all patients (95% confidence interval, 53.0%-68.5%) and was similar between sexes (hazard ratio, 0.95; P = .83), which were the primary endpoints. No sex differences in midterm follow-up reintervention, endoleak, and rupture rates were observed. CONCLUSIONS: Females experienced significantly higher B/FEVAR intraoperative times, complications, and in-hospital morbidity and mortality compared with males but similar midterm outcomes. Anatomic and atherosclerotic differences may have contributed to the observed in-hospital differences.

Pregnancy Outcomes in Canadian Women With Disabilities: Results From Linked Survey and Health Administrative Data.

We compared maternal, labour/delivery, and birth outcomes in women with versus without disabilities using a linkage of 2003-2014 Canadian Community Health Survey (CCHS) and 2003-2017 Discharge Abstract Database data. Modified Poisson regression was used to compare 15-49-year-old women with (n = 2430) and without (n = 10 375) disabilities with a singleton birth ≤5 years after their CCHS interview. Women with disabilities were at elevated risk of prenatal hospitalization (10.3% vs. 6.6%; adjusted prevalence ratio 1.33, 95% CI 1.03-1.72). They were also at elevated risk of preterm birth (8.7% vs. 6.2%), but this was attenuated after adjustment. Women with disabilities could benefit from tailored prenatal care.

Preconception health disparities among reproductive-aged women with and without disabilities in Canada.

OBJECTIVES: Preconception health (PCH), which describes the health status of reproductive-aged individuals, can influence reproductive, maternal, and fetal/neonatal outcomes. PCH disparities have been observed in certain populations, prompting the development of tailored resources. Our objective was to compare the PCH characteristics of women with and without disabilities. METHODS: We undertook a secondary analysis of the 2003-2014 cycles of the Canadian Community Health Survey (CCHS), which included n = 115,295 women aged 15-49 years. Among these, we also examined a sub-sample of n = 12,495 women with a subsequent obstetrical delivery identified in a linkage of the CCHS with the Discharge Abstract Database (DAD, 2003-2017). The outcomes were 8 PCH indicators. We used modified Poisson regression to estimate adjusted prevalence ratios (aPRs) for each PCH indicator, comparing women with and without disabilities, and multinomial logistic regression to calculate adjusted odds ratios for 1, 2, and ≥ 3 PCH indicators (vs. 0). Analyses were adjusted for baseline demographics. RESULTS: Reproductive-aged women with disabilities had significantly increased aPRs of smoking (1.42 [95% CI:1.37-1.48]), obesity (1.57 [1.48-1.65]), and self-reported fair/poor physical (5.56 [5.09-6.07]) and mental health (4.07 [3.71-4.47]), compared to those without disabilities. They were also more likely to have ≥ 3, 2, and 1 PCH indicators (vs. 0). Findings were similar in the sub-sample with a subsequent obstetrical delivery. CONCLUSION: Canadian reproductive-aged women with disabilities experience important PCH disparities. Further research is needed to inform tailored education and resources to support PCH in individuals with disabilities, in combination with policies to address structural barriers to PCH.

RéSUMé: OBJECTIFS: La santé préconceptionnelle (SPC), qui décrit l'état de santé des personnes en âge de procréer, peut influencer les résultats reproductifs, maternels et fœtaux/néonataux. Des disparités en matière de SPC ont été observées dans certaines populations, ce qui a conduit à la mise en place de ressources adaptées. Notre objectif était de comparer les caractéristiques de la SPC des femmes handicapées et non handicapées. MéTHODES: Nous avons entrepris une analyse secondaire des cycles 2003­2014 de l'Enquête sur la santé dans les collectivités canadiennes (ESCC), qui comprenait n = 115 295 femmes âgées de 15 à 49 ans. Parmi celles-ci, nous avons également examiné un sous-échantillon de n = 12 495 femmes ayant subi un accouchement obstétrique subséquent, identifiées dans le cadre d'un couplage de l'ESCC avec la Base de données sur les congés des patients (BDCP, 2003‒2017). Les résultats étaient 8 indicateurs de la SPC. Nous avons utilisé la régression de Poisson modifiée pour estimer les ratios de prévalence ajustés (aPR) pour chaque indicateur SPC, en comparant les femmes avec et sans handicap, et la régression logistique multinomiale pour calculer les rapports de cotes ajustés pour 1, 2 et ≥ 3 indicateurs SPC (par rapport à 0). Les analyses ont été ajustées en fonction des données démographiques de base. RéSULTATS: Les femmes handicapées en âge de procréer présentaient des aPR significativement plus élevés de tabagisme (1,42 [IC 95%: 1,37 à 1,48]), d'obésité (1,57 [1,48 à 1,65]) et de santé physique (5,56 [5,09 à 6,07]) et mentale (4,07 [3,71 à 4,47]) auto déclarée passable/mauvaise, par rapport à celles qui n'avaient pas de handicap. Elles étaient également plus susceptibles d'avoir ≥ 3, 2 et 1 indicateurs SPC (par rapport à 0). Les résultats étaient similaires dans le sous-échantillon avec un accouchement obstétrical ultérieur. CONCLUSION: Les femmes handicapées en âge de procréer au Canada connaissent d'importantes disparités en matière de SPC. D'autres recherches sont nécessaires pour fournir une éducation et des ressources adaptées afin de soutenir la SPC chez les personnes handicapées, en combinaison avec des politiques visant à éliminer les obstacles structurels à la SPC.

The association between off- and on-premise alcohol outlet density and 100% alcohol-attributable emergency department visits by neighbourhood-level socioeconomic status in Ontario, Canada.

Alcohol availability is positively associated with alcohol use and harms, but the influence of socioeconomic status (SES) on these associations is not well established. This population-based cross-sectional study examined neighbourhood-level associations between physical alcohol availability (measured as off- and on-premise alcohol outlet density) and 100% alcohol-attributable emergency department (ED) visits by neighbourhood SES in Ontario, Canada from 2017 to 2019 (n = 19,740). A Bayesian spatial modelling approach was used to assess associations and account for spatial autocorrelation, which produced risk ratios (RRs) and 95% credible intervals (95% CrI). Each additional off-premise alcohol outlet in a neighbourhood was associated with a 3% increased risk of alcohol-attributable ED visits in both men (RR = 1.03, 95%CrI: 1.02-1.04) and women (RR = 1.03, 95% CrI: 1.02-1.04). Positive associations were also observed between on-premise alcohol outlet density and alcohol-attributable ED visits, although effect sizes were small. A disproportionately greater association with ED visits was observed with increasing alcohol outlet density in the lowest compared to higher SES neighbourhoods. Reducing physical alcohol availability may be an important policy lever for reducing alcohol harm and alcohol-attributable health inequities.

Can a health warning label diminish the persuasive effects of health-oriented nutrition advertising on ready-to-drink alcohol product packaging? A randomized experiment.

BACKGROUND AND AIMS: A health warning label (HWL) cautioning about the link between alcohol and cancer may be able to communicate alcohol risks to consumers and potentially counter health-oriented nutrition advertising on ready-to-drink alcoholic beverages. This study aimed to examine the independent and combined effects of nutrient content claims (e.g. 0 g sugar) and a HWL on perceived product characteristics and intentions to consume, and whether these effects differed by gender and age. DESIGN: A between-subjects randomized experiment. Participants were randomized to view one of six experimental label conditions: nutrient content claims plus nutrition declaration (NCC + ND), ND only, NCC + ND + HWL, ND + HWL, HWL only and no NCC, ND or HWL, all on a ready-to-drink (RTD) vodka-based soda container. SETTING AND PARTICIPANTS: Alcohol consumers (n = 5063; 52% women) in Canada aged 18-64 recruited through a national online panel. MEASUREMENTS: Participants completed ratings of perceived product characteristics, perceived product health risks, and intentions to try, buy, binge and drink the product. FINDINGS: Compared with the reference condition NCC + ND (current policy scenario in Canada), the other five experimental label conditions were associated with lower ratings for perceiving the product as healthy. All experimental conditions with a HWL were associated with lower product appeal, higher risk perceptions and reduced intentions to try, buy and binge. The experimental condition with a HWL only was associated with intentions to consume fewer cans in the next 7 days (ß = -0.72, 95% confidence interval [CI] = -1.37,-0.08) versus the reference. Few interactions were observed, suggesting that label effects on outcomes were similar by gender and age. CONCLUSIONS: Health warning labels on alcohol packaging appear to be associated with lower product appeal, higher perceived health risks and reduced consumption intentions, even in the presence of nutrient content claims.
