RESUMO

OBJECTIVES: Abdominal Aortic Aneurysms (AAA) in females are less prevalent, have higher expansion rates and experience rupture at smaller diameters than in males. Studies have compared outcomes of the retroperitoneal (RP) and transperitoneal (TP) approach in open aortic aneurysm repair (OAR) with conflicting results. No study to date has compared the two approaches solely in females. In this study we compare midterm outcomes of the RP and TP approach in females undergoing OAR. METHODS: Single-center, retrospective review of all females undergoing OAR from 2010 to 2021. Patients undergoing elective, symptomatic and ruptured OAR were included. The cohort was stratified by surgical approach RP versus TP and midterm outcomes were compared amongst the groups. Outcomes included mortality, graft related, and non-graft related complications. RESULTS: A total of 244 patients (RP n = 133; TP n = 111) were identified. Follow-up period was 28 ± 30.7 months. Baseline perioperative characteristics were similar except that more people in the RP group had ejection fraction ((EF) > 50% (82% vs 68%), p = .037). Patients who underwent RP repair had longer visceral/renal ischemia time (p = .01), larger graft diameter (18 vs 16 mm; p = <0.001), were more likely to have a suprarenal clamp placed(70.5 vs 48.2; p < .001), and had decreased autotransfusion volume (611 vs 861 mL; p < .01) compared to those who underwent TP repair. Number of deaths was higher in the TP group during study follow-up period (36.4 vs 23.8; p = .035), but the difference of the time to event analysis was not significant. There was no difference in all-cause survival at 36 months between RP and TP (77.8 vs 76.8; p = .045). Overall midterm complications were 9.5% in both groups. Any graft related complication was 1.8% in TP versus 3% RP (p = .69). In a multivariable model, after adjusting for age, urgency, smoking, prior aneurysm repair, and ASA level, the hazard ratio decreases with the RP approach, however this did not reach significance (p = .052). CONCLUSION: In a 12-year period of OAR in females, TP and RP results were comparable at midterm analysis. The RP approach appeared to be used more often for OAR requiring suprarenal clamping. Although the TP group had increased mortality, the difference of the time to event analysis was not significant. Midterm postoperative complications in both groups were low. This suggests that both approaches are safe in the female population and decision should be driven by anatomy and surgeon's preference.

RESUMO

BACKGROUND: Cardiovascular complications are a major cause of morbidity and mortality in the postoperative period after major vascular surgery. Depending on the study population, up to 25% of patients have troponin elevation after noncardiac surgery, yet many do not meet the diagnosis of myocardial infarction (MI). Although outcomes of routine troponin elevation in patients undergoing mixed major vascular surgery have been evaluated, this has not been studied exclusively in elective, open abdominal aortic aneurysm repair (oAAA), especially regarding perioperative and overall mortality. METHODS: We conducted a single-center, retrospective review of routine troponin surveillance for consecutive, oAAA from 2014 to 2019. A total of 319 patients were identified and analyzed for management patterns and interventions. The cohort was stratified into groups for comparison based on those in whom troponin was routinely checked (RC) as part of a care strategy during the study period, not routinely checked (NRC), elevated troponin (ET) >0.001 ng/mL, and not elevated. The median follow-up was 21.5 ± 23.8 months. Groups were compared on demographic data, cardiac comorbidities, 30-day and 3-year outcomes for MI and death using two-sample t-tests, Wilcoxon rank sum tests, Pearson chi-square tests, and Fisher exact tests when appropriate. RESULTS: Troponin was measured in 83.7% (267/319) of patients who underwent elective oAAA repair. Routine troponin checks were obtained in 79.9% (255/319) of patients. ET was identified in 16.5% of those with RC (42/255) and 4.7% of those with NRC (3/64). Of patients with ET, 37.8% (17/45) had a cardiology consultation, 4.4% (2/45) had a percutaneous coronary intervention (PCI), and 4.4% (2/45) had another cardiac intervention. All 4 patients undergoing PCI or other cardiac intervention had received routine troponin checks. Patients with ET were older (71.2 vs. 68.6; P = 0.04), more likely to receive intraoperative blood products (P = 0.003), had longer operative times (P = 0.011), higher length of stay (9 vs. 7 days; P < 0.01), and higher 30-day MI rate (3 vs. 0; P = 0.04). They had neither longer aortic clamp times nor worse preoperative cardiac function, and the proximal clamp position during oAAA repair did not impact troponin detection. Additionally, 3-year overall mortality was increased in patients who had ET but there was not a significant difference in 3-year mortality between groups receiving routine troponin checks versus not. CONCLUSIONS: ET, identified after elective oAAA repair, was associated with a higher risk of 30-day MI and lower overall survival. However, it was not demonstrated that routine assessment of troponin levels postoperatively leads to decreased 3-year mortality in this setting.
