Endovascular repair or open repair for ruptured abdominal aortic aneurysm: a Cochrane systematic review.

ABSTRACT: OBJECTIVES:Emergency endovascular aneurysm repair (eEVAR) may improve outcomes for patients with ruptured abdominal aortic aneurysm (RAAA). The study aim was to compare the outcomes for eEVAR with conventional open surgical repair for the treatment of RAAA. SETTING:A systematic review of relevant publications was performed. Randomised controlled trials (RCTs) comparing eEVAR with open surgical repair for RAAA were included. PARTICIPANTS:3 RCTs were included, with a total of 761 patients with RAAA. INTERVENTIONS:Meta-analysis was performed with fixed-effects models with ORs and 95% CIs for dichotomous data and mean differences with 95% CIs for continuous data. PRIMARY AND SECONDARY OUTCOME MEASURES:Primary outcome was short-term mortality. Secondary outcome measures included aneurysm-specific and general complication rates, quality of life and economic analysis. RESULTS:Overall risk of bias was low. There was no difference between the 2 interventions on 30-day (or in-hospital) mortality, OR 0.91 (95% CI 0.67 to 1.22; p=0.52). 30-day complications included myocardial infarction, stroke, composite cardiac complications, renal complications, severe bowel ischaemia, spinal cord ischaemia, reoperation, amputation and respiratory failure. Reporting was incomplete, and no robust conclusion was drawn. For complication outcomes that did include at least 2 studies in the meta-analysis, there was no clear evidence to support a difference between eEVAR and open repair. Longer term outcomes and cost per patient were evaluated in only a single study, thus precluding definite conclusions. CONCLUSIONS:Outcomes between eEVAR and open repair, specifically 30-day mortality, are similar. However, further high-quality trials are required, as the paucity of data currently limits the conclusions.

Project description:PurposeThe PEVAR Trial demonstrated that compared to open femoral exposure, elective percutaneous endovascular AAA repair (ePEVAR) is associated with decreased perioperative morbidity and access site complications. We hypothesized that PEVAR for ruptured AAA (rPEVAR) may also improve perioperative morbidity compared to open femoral exposure (rEVAR). There are currently no reports that evaluate the utility and outcomes of rPEVAR.Materials and methodsFrom 2015 to 2021, all patients who underwent an endovascular repair of a ruptured AAA at a single institution were included in the study and grouped into rPEVAR and rEVAR. Demographics, procedural details (successful preclose technique, conversion to femoral cutdown), postoperative variables (blood transfusion, ICU and hospital length of stay) and short-term outcomes (30-day major adverse events (30-day MAE) and 30-day femoral access-site complications (30-day FAAC)) were collected and compared with 50 historical ePEVAR patients from the PEVAR Trial. Statistical significance was determined using χ 2 or Fisher's exact test for categorical variables, and Mann-Whitney U-test for continuous variables.Results35 patients were identified (21 rPEVAR; 14 rEVAR), 86% were male with a mean age of 72 ± 9 years. All patients underwent emergent endovascular aortic repair with 100% technical success. Seventeen patients (49%) presented with evidence of hemorrhagic shock and 22 patients (63%) had blood transfusion. 30-day MAE occurred in 12 patients (34%) (7 rPEVAR; 5 rEVAR). There was no difference in demographic, perioperative outcomes and 30-day MAE rate between rPEVAR and rEVAR patients. Compared to ePEVAR patient (from PEVAR trial), rPEVAR patients had higher rate of 30-day MAE (34% vs. 6%; p < 0.006) but no difference in 30-day FAAC (19% vs. 12%; p = 0.54). The success rate of the preclose technique was higher in ePEVAR compared to rPEVAR (96% vs. 76%; p = 0.02), but the rate of conversion to femoral cutdown was similar between the two groups (10% vs. 4%; p = 0.57).ConclusionEmergent rPEVAR appears to have similar outcomes when compared to rEVAR. Although patients undergoing rPEVAR have higher 30-day major adverse events rate compared to ePEVAR, the method of percutaneous femoral cannulation does not appear to increase the overall procedural or 30-day femoral artery access-site complications.

Project description:BackgroundMultiple organ failure (MOF) is associated with poor outcomes and increased mortality in sepsis and trauma. There are limited data regarding MOF in patients after ruptured abdominal aortic aneurysm (rAAA) repair. We aimed to identify the contemporary prevalence and characteristics of patients with rAAA with MOF.MethodsWe retrospectively reviewed patients with rAAA who underwent repair (2010-2020) at our multihospital institution. Patients who died within the first 2 days after repair were excluded. MOF was quantified by modified (excluding hepatic system) Denver, Sequential Organ Failure Assessment (SOFA) score, and Multiple Organ Dysfunction Score (MODS) for postoperative days 3 to 5 to determine the prevalence of MOF. MOF was defined as a Denver score of >3, dysfunction in two or more organ systems by SOFA score, or a MODS score of >8. Kaplan-Meier curves and log-rank testing were used to evaluate differences in 30-day mortality between multiple organ failure and patients without MOF. Logistic regression was used to assess predictors of MOF.ResultsOf 370 patients with rAAA, 288 survived past two days (mean age, 73±10.1 years; 76.7% male; 44.1% open repair), and 143 had data for MOF calculation recorded. From postoperative days 3 to 5, 41 (14.24%) had MOF by Denver, 26 (9.03%) by SOFA, and 39 (13.54%) by MODS criteria. Among these scoring systems, pulmonary and neurological systems were impacted most commonly. Among patients with MOF, pulmonary derangement occurred in 65.9% (Denver), 57.7% (SOFA), and 56.4% (MODS). Similarly, neurological derangement occurred in 92.3% (SOFA) and 89.7% (MODS), but renal derangement occurred in 26.8% (Denver), 23.1% (SOFA), and 10.3% (MODS). MOF by all three scoring systems was associated with increased 30-day mortality (Denver: 11.3% vs 41.5% [P < .01]; DOFA: 12.6% vs 46.2% [P < .01]; MODS: 12.5% vs 35.9% [P < .01]), as was MOF by any criteria (10.8% vs 35.7 %; P < .01). Patients with MOF were more likely to have a higher body mass index (55.9±26.6 vs 49.0±15.0; P = .011) and to have had a preoperative stroke (17.9% vs 6.0%; P = .016). Patients with MOF were less likely to have undergone endovascular repair (30.4% vs 62.1%; P < .001). Endovascular repair was protective against MOF (any criteria) on multivariate analysis (odds ratio, 0.23; 95% confidence interval, 0.08-0.64; P = .019) after adjusting for age, gender, and presenting systolic blood pressure.ConclusionsMOF occurred in only 9% to 14% of patients after rAAA repair, but was associated with a three-fold increase in mortality. Endovascular repair was associated with a reduced MOF incidence.
