ObjectiveIn the present study, we used a national database to identify racial differences in the presentation and outcomes for patients undergoing endovascular abdominal aortic aneurysm (AAA) repair (EVAR) and identified areas for improving their care.MethodsWe queried the EVAR-targeted National Surgical Quality Improvement Program database (2016-2019) to identify patients who had undergone EVAR for both ruptured and nonruptured AAAs. The patients were categorized according to race (White, Black, and Asian). Patients with a history of abdominal aortic surgery or an indication other than AAAs were excluded. The data was analyzed using the χ2 and Kruskal-Wallis tests, presented as frequencies and percentages or median and interquartile range (IQR) for categorical and continuous variables, respectively.ResultsWe identified 3629 patients (16.6% female), including 3312 White (91.3%), 248 Black (6.8%), and 69 Asian (1.9%) patients. Black patients were more frequently women (27.0%) compared with White patients (15.9%) and were younger (median age, 71 years; IQR, 64-77 years) than White (median age, 73 years; IQR, 67-79 years) and Asian (median age, 76 years; IQR, 67-81 years) patients (P < .001 for both). The incidence of smoking, congestive heart failure, and dialysis dependency was highest for Black patients, and the incidence of obesity was lowest for Asian patients. The AAAs in Black patients extended more frequently beyond the aortic bifurcation (P = .047). In Asian patients, the internal iliac arteries were more involved (P = .040). For Black patients, 29.8% of the EVARs were performed in a nonelective setting compared with 20.2% for the White and 15.9% for the Asian patients (P < .001). The aneurysm diameter, nonruptured symptomatic rate, and rupture rate were similar across the groups (P = .807). The operative time was prolonged for Black (median, 128 minutes; IQR, 96-177 minutes) compared with White (median, 114 minutes; IQR, 84-162 minutes) patients (P < .001). Postoperatively, Black patients were more likely to require blood transfusion (16.5%) and had prolonged length of hospital stay (median, 2 days; IQR, 1-4 days) compared with White (10.0%; median, 1 day; IQR, 1-3 days) and Asian (4.3%; median, 1 day; IQR, 1-3 days) patients (P = .001 and P < .001, respectively). Black patients also had a higher 30-day readmission rate (P = .038). On multivariate analysis, Black race was an independent factor for length of stay >1 day after both elective and nonelective EVAR and 30-day readmission for elective EVAR, but not 30-day mortality after elective and nonelective EVAR.ConclusionsIn the present nationwide sample of EVAR cases, Black patients were more often women and younger. Despite similar rates of symptomatic and ruptured AAAs at presentation and 30-day mortality, Black patients more often presented and were treated during the same nonelective admission; they also had associated increased length of hospital stay and readmission. These findings signal a missed opportunity to diagnose, optimize, and treat this particular group of patients in an elective setting. 相似文献

Objective
We evaluated the association between postoperative hyperglycemia and outcomes after abdominal aortic aneurysm (AAA) repair.Methods
We used diagnosis and procedure codes (International Classification of Diseases, Ninth Revision, Clinical Modification) to identify patients who underwent open or endovascular repair of a nonruptured AAA from September 2008 to March 2014 from the Cerner Health Facts database (Cerner Corporation, North Kansas City, Mo). We evaluated the association between postoperative hyperglycemia (glucose concentration >180 mg/dL) and infections, in-hospital mortality, readmission, patients' characteristics, length of hospital stay, and medications. Multivariable logistic models examined the association of postoperative hyperglycemia with in-hospital infection and mortality.Results
Of 2478 patients, 2071 (83.5%) had good postoperative glucose control (80-180 mg/dL), and 407 (16.5%) had suboptimal control (hyperglycemia). Patients who had postoperative hyperglycemia experienced longer hospital stays (9.5 vs 4.7 days; P < .0001), higher infection rates (18% vs 8%; P < .0001), higher in-hospital mortality (8.4 vs 1.2%; P <.0001), and more acute complications (ie, acute renal failure, fluid and electrolyte disorders, respiratory complications). After adjusting for patients' characteristics and medications, multivariable logistic regression models demonstrated that patients receiving postoperative insulin had nearly 1.6 times the odds of having an infectious complication (odds ratio [OR], 1.6; 95% confidence interval [CI], 1.12-2.2; P = .007) than those who did not. Hyperglycemic patients had 3.5 times the odds of in-hospital mortality (OR, 3.48; 95% CI, 1.78-6.80 [P = .0003]; 2.3% vs 1.2%; P < .001). When stratified by procedure type, patients with hyperglycemia who underwent endovascular repair had nearly 2 times the odds of an infectious complication (OR, 1.85; 95% CI, 0.98-3.51; P = .05) and 7.5 times the odds of in-hospital mortality (OR, 7.54; 95% CI, 1.95-29.1; P = .003). Patients who underwent an open AAA repair and who had hyperglycemia had three times the odds of dying in the hospital (OR, 3.05; 95% CI, 1.29-7.21; P = .01).Conclusions
Among patients undergoing elective AAA repair, approximately one in six had postoperative hyperglycemia. After AAA repair in patients with and without diabetes, postoperative hyperglycemia was associated with adverse events, including in-hospital mortality and infections. Compared with those who had open surgery, patients undergoing endovascular repair who had postoperative hyperglycemia had greater risk of infection and death. After controlling for insulin administration and postoperative hyperglycemia, a diabetes diagnosis was associated with lower odds of both infection and in-hospital mortality. Our study suggests that hyperglycemia may be used as a clinical marker as it was found to be significantly associated with inferior outcomes after elective AAA repair. This retrospective study, however, cannot imply causation; further study using prospective methods is needed to elucidate the relationship between postoperative hyperglycemia and patient outcomes. 相似文献12.

Background
Endovascular aneurysm sealing (EVAS) represents a novel approach to the treatment of abdominal aortic aneurysms. It uses polymer technology to achieve an anatomic seal within the sac of the aneurysm. This cohort study reports the early clinical outcomes, technical refinements, and learning curve during the initial EVAS experience at a single institution.Methods
Results from 150 consecutive EVAS cases for intact, infrarenal abdominal aortic aneurysms are reported here. These cases were undertaken between March 2013 and July 2015. Preoperative, perioperative, and postoperative data were collected for each patient prospectively.Results
The median age of the cohort was 76.6 years (interquartile range, 70.2-80.9 years), and 87.3% were male. Median aneurysm diameter was 62.0 mm (IQR, 58.0-69.0 mm). Adverse neck morphology was seen in 69 (46.0%) patients, including aneurysm neck length <10 mm (17.3%), neck diameter >32 mm or <18 mm (8.7%), and neck angulation >60 degrees (15.3%). Median follow-up was 687 days (IQR, 463-897 days); 37 patients (24.7%) underwent reintervention. The rates of unresolved endoleak are 1.3% type IA, 0.7% type IB, and 2.7% type I. There were no type III endoleaks. There have been seven secondary ruptures in this cohort; all but one of these patients survived after reintervention. Only one rupture occurred in an aneurysm that had been treated within the manufacturer's instructions for use (IFU).Conclusions
The rate of unresolved endoleaks is satisfactorily low. The incidence of secondary rupture is of concern; however, when the IFU are adhered to, the rate is very low. The results of this study suggest that working within the IFU yields better clinical results. 相似文献14.

BackgroundEndovascular aneurysm sealing (EVAS), using the Nellix endovascular aneurysm sealing system, has been associated with high reintervention and migration rates. However, prior reports have suggested that EVAS might be related to a lower all-cause mortality compared with endovascular aneurysm repair (EVAR). In the present study, we examined the 5-year all-cause mortality trends after EVAS and EVAR.MethodsWe compared the 333 EVAS patients in the EVAS-1 Nellix U.S. investigational device exemption trial with 16,497 infrarenal EVAR controls from the Vascular Quality Initiative, treated between 2014 and 2016, after applying the exclusion criteria from the investigational device exemption trial (ie, hemodialysis, creatinine >2.0 mg/dL, rupture). As a secondary analysis, we stratified the patients by aneurysm diameter (<5.5 cm and ≥5.5 cm). We calculated propensity scores after adjusting for demographics, comorbidities, and anatomic characteristics and applied inverse probability weighting to compare the risk-adjusted long-term mortality using Kaplan-Meier and Cox regression analyses.ResultsAfter weighting, the EVAS group had experienced similar 5-year mortality compared with the controls from the Vascular Quality Initiative (EVAS vs EVAR, 18% vs 14%; hazard ratio [HR], 1.1; 95% confidence interval [CI], 0.71-1.7; P = .70). The subgroup analysis demonstrated that for patients with an aneurysm diameter of <5.5 cm, EVAS was associated with higher 5-year mortality compared with EVAR (19% vs 11%; HR, 2.4; 95% CI, 1.7-4.7; P = .013). In patients with an aneurysm diameter of ≥5.5 cm, EVAS was associated with lower mortality within the first 2 years (2-year mortality: HR, 0.29; 95% CI, 0.13-0.62; P = .002). However, compared with EVAR, EVAS was associated with higher mortality between 2 and 5 years (HR, 1.9; 95% CI, 1.2-3.0; P = .005), with no mortality difference at 5 years (18% vs 17%; HR, 0.82; 95% CI, 0.4-1.4; P = .46).ConclusionsWithin the overall population, EVAS was associated with similar 5-year mortality compared with EVAR. EVAS was associated with higher mortality for those with small aneurysms (<5.5 cm). For those with larger aneurysms (≥5.5 cm), EVAS was initially associated with lower mortality within the first 2 years, although this advantage was lost thereafter, with higher mortality after 2 years. Future studies are required to evaluate the specific causes of death and to elucidate the potential beneficial mechanism behind sac obliteration that leads to this potential initial survival benefit. This could help guide the development of future grafts with better proximal fixation and sealing that also incorporate sac obliteration. 相似文献

ObjectivePatients with abdominal aortic aneurysm (AAA) frequently have simple renal cyst (SRC), a common manifestation of connective tissue degeneration. This study aimed to determine whether SRC is a risk factor for failure of sac shrinkage after endovascular aneurysm repair (EVAR).MethodsBetween October 2013 and May 2017, there were 155 consecutive patients with an infrarenal AAA or a common iliac artery aneurysm who underwent EVAR with the GORE C3 Excluder (W. L. Gore & Associates, Flagstaff, Ariz) at Tokyo Medical University Hospital. All these patients were registered in a prospectively maintained database. Any kidney lesion >5 mm in diameter, with no evidence of contrast enhancement or septation and with low attenuation, was defined as SRC. A change in sac size of >5 mm from baseline was considered significant. The patients were divided into those with SRC and those without SRC, and sac shrinkage at 1 year and 2 years was compared. The presence of SRC was assessed with respect to being a risk factor for failure of sac shrinkage at 1 year using univariate and multivariable logistic regression analysis.ResultsThe patients were divided into two groups: those with SRC (92 patients [59.0%]) and those without SRC (63 patients [41.0%]). At 1 year and 2 years, significant differences were observed in the proportion of sac shrinkage between patients with SRC and those without SRC (19.2% vs 42.4% [P = .003] and 19.6% vs 53.3% [P = .001], respectively). Patients with SRC showed significantly less sac shrinkage than those without SRC at 1 year and 2 years (−2.0 ± 5.5 mm vs −4.4 ± 6.2 mm [P = .002] and −1.8 ± 6.3 mm vs −6.4 ± 8.6 mm [P = .005], respectively). Multivariable analysis demonstrated that SRC (odds ratio, 0.28; 95% confidence interval, 0.12-0.63; P = .002) and initial sac size (odds ratio, 1.05; 95% confidence interval, 1.01-1.09; P = .027) were positive and negative risk factors for sac shrinkage, respectively.ConclusionsThe presence of SRC is a risk factor for failure of sac shrinkage after EVAR. This suggests that AAA in patients with SRC has a more degenerated wall than in those without SRC. The property of the aneurysm wall may be associated with sac shrinkage after EVAR. 相似文献

OBJECTIVE: Large databases composed of well-designed prospectively collected cohort data provide an opportunity to examine and compare healthcare treatments in actual clinical practice settings. Because the analysis of these data often leads to a retrospective cohort design, it is essential to adequately adjust for lack of balance in patient characteristics when making treatment comparisons. We used matched propensity scoring in a cohort of patients undergoing elective aneurysm repair as an illustrative example of this important statistical method that adjusts for baseline characteristics and selection bias by matching covariables. METHODS: By using prospectively collected clinical data from the National Surgical Quality Improvement Program of the Department of Veterans Affairs, we studied 30-day mortality, 1-year survival, and postoperative complications in 1904 patients who underwent elective AAA repair (endovascular aneurysm repair [EVAR], n=717 (37.7%); open aneurysm repair, n=1187 [62.3%]) at 123 Veterans Health Administration's hospitals between May 1, 2001, and September 30, 2003. In bivariate analysis, patient characteristics and operative and hospital variables were associated with both type of surgery and outcomes of surgery. Therefore, the predicted probability of receiving EVAR was tabulated for all patients by using multiple logistic regression to control for 32 independent demographic and clinical characteristics and then stratified into 5 groups. Patients were matched within strata based on similar levels of the independent measures (a propensity score technique), creating a pseudo-randomized control design. The proportion of patients with the morbidity and mortality outcomes was then compared between the EVAR and open procedures within strata to control for selection. RESULTS: Patients undergoing EVAR had significantly lower unadjusted 30-day (3.1% versus 5.6%, P=.01) and 1-year mortality (8.7% versus 12.1%, P=.018) than patients undergoing open repair. By using propensity scoring, the proportions of EVAR patients experiencing 30-day mortality were equal or less than patients undergoing open procedures for all levels of probability and decreased as the probability of EVAR increased. Furthermore, propensity scoring also showed that patients having EVAR had lower 1-year mortality and experienced fewer perioperative complications. CONCLUSIONS: We used a propensity score approach to examine outcomes after elective AAA repair to statistically control for many factors affecting both treatment selection and outcome. Patients who underwent elective EVAR had substantially lower perioperative mortality and morbidity rates compared with patients having open repair, which was not explained solely by patient selection in an observational dataset. 相似文献

BackgroundEvidence to guide management of postdissection abdominal aortic aneurysms (PDAAA) is lacking. This study describes the outcomes of open repair of PDAAA.MethodsA retrospective cohort study was conducted of all consecutive patients treated with open repair for PDAAA after a Stanford type A or type B thoracic aortic dissection between January 2006 and December 2017 in two vascular referral centers. Preceding type B dissection treatment could include conservative or surgical management. Primary outcomes were 30-day mortality, complication rates, survival, and reintervention-free survival. Survival and reintervention-free survival were analyzed using the Kaplan-Meier method. Reintervention was defined as any endovascular or surgical intervention after the index procedure.ResultsIncluded were 36 patients (27 men [75%]) with a median age of 64 years (range, 35-81 years). The 30-day mortality was 2.7%. The median follow-up was 16 months (range, 0-88 months). The postoperative course was uneventful in 21 patients (58%). The most frequent complications were postoperative bleeding requiring repeat laparotomy (n = 4), pneumonia (n = 3), congestive heart failure (n = 2), new-onset atrial fibrillation (n = 2), mesenteric ischemia requiring left hemicolectomy (n=1), and ischemic cerebrovascular accident (n = 1). Renal failure requiring hemodialysis developed in one patient. The overall survival at 1 year was 88.8%. Reintervention-free survival was 95.5% after 1 year and 88.6% after 2 years.ConclusionsOpen repair of PDAAA can be performed with a low mortality rate and an acceptable complication rate, comparable with elective open repair of abdominal aortic aneurysms without dissection. 相似文献
