Abstract
Background Endovascular aneurysm repair (EVAR) is associated with decreased perioperative morbidity and mortaliy in comparison with open repair, and thus octagenarians are traditionally offered EVAR given their age and medical comorbidities. The aim of this study was to investigate outcomes and predictors of complications associated with EVAR in octogenarians. Methods We conducted a retrospective chart review of consecutive patients aged 80 years and older who received an EVAR between August 2010 and January 2017 at a single centre in Toronto, Ontario. We conducted univariate comparisons and then completed logistic regression to determine predictors of complications. We used Kaplan-Meier analysis to explore survival times. Results A total of 154 octogenarians underwent an EVAR during the study period for an infrarenal aneurysm with a mean size of 64.8 (standard deviation [SD] 12.7) mm. The mean age of the patients was 84.1 (SD 3.7) years, and most patients (81%) were men. Eighteen patients presented with a ruptured abdominal aortic aneurysm (AAA). Ninety-five (62%) patients sustained a complication. Fifty percent of patients experienced an intraoperative complication. A majority of these (77%) resulted in an endoleak, with type II endoleaks requiring no further intervenion being the most common (58%, n = 45). The remaining complications (n = 70) occurred postoperatively, with myocardial ischemia (n = 24) and dysrhythmias (n = 10) being the most common. Past aortic surgery (χ2 = 8.62, p = 0.014, Cramer V = 0.27) was found to be a multivariate predictor of complications. Most patients (88%) continued follow-up to an average of 20.9 months. Twenty-one patients (13%) died. Nine of these deaths (43%) occurred during the index admission and involved a ruptured AAA. Past aortic surgery was the only predictor of vascular complications. The mean survival time after EVAR was 57.63 months for patients without events. Conclusion Endovascular aneurysm repair in octogenarians is a suitable form of therapy with acceptable short- and long-term results in the elective setting. Past aortic surgery was a predictor of complications in this population.

Abstract
Operative survival is as high as 96% for elective abdominal aortic aneursym (AAA) repair but as low as 10% for emergency repair. Our primary aim was to compare elective AAA repair in octogenarians with nonoperative management. Our secondary aim was to compare octogenarians with their younger counterparts. From 1998 to 2003, 180 patients with AAA were treated operatively or nonoperatively. Factors determining treatment included American Society of Anesthesiologists grade ≥ 4, inoperable malignancy, New York Heart Association class III, forced expiratory volume in 1 second < 35%, creatinine > 6.0 mg/dL, and patient and family choice. A parallel-group observational study was performed to assess age and treatment effects on outcome. Seventy (39%) patients were repaired electively, 68 (38%) were managed nonoperatively, and 42 (23%) underwent emergency repair. Fifty-nine (33%) were octogenarians. The octogenarian 5-year survival rate was 20% following emergency repair, 42% if treated nonoperatively, and 83% following elective repair. Younger cohort rates were 55% (emergency), 44% (nonoperative), and 76% (elective). The octogenarian mean expansion rate was 0.26 cm/yr in those treated nonoperatively and 1.04 cm/yr in confirmed rupture. Rupture rate was related to expansion rate (95% confidence interval [CI] 0.06–0.59, r = .35, p = .01). The rates in the younger subgroup were 0.32 cm/yr and 1.14 cm/yr (95% CI −0.021–0.672}, r = .37, p = .03). The octogenarian survival rate was highest following elective repair. Rupture was closely correlated with aneurysm expansion. Screening should reduce the incidence of octogenarian rupture of AAA and identify those patients most suitable for nonoperative management.

Abstract
The objective of the Amsterdam Acute Aneurysm Trial is to study the combined outcome of conventional emergency surgery versus endovascular treatment for ruptured abdominal aortic aneurysms. The design used was a multicenter randomized clinical trial conducted in two university hospitals and one teaching hospital in the Amsterdam region. The study included all patients with a ruptured abdominal aneurysm who were eligible for endovascular and conventional surgery. The primary end points were combined mortality and severe morbidity. The secondary end points were quality of life and cost-effectiveness. The background, design, and methods of this trial are presented, and the ethical and legal issues of this type of research are discussed.

Abstract
Increasing life expectancies paired with age-related comorbidities have resulted in the continued growth of the elderly surgical population. In this group, age-associated changes and decreased physiological reserve impede the body's ability to maintain homeostasis during times of physiological stress, with a subsequent decrease in physiological reserve. This can lead to age-related physiological and cognitive dysfunction resulting in perioperative complications. Changes in the cardiovascular, pulmonary, nervous, hepatorenal, endocrine, skin, and soft tissue systems are discussed as they are connected to the perioperative experience. Alterations affect both the pharmacodynamics and pharmacokinetics of administered drugs. Elderly patients with coexisting diseases are at a greater risk for polypharmacy that can further complicate anesthetic management. Consequently, the importance of conducting a focused preoperative evaluation and identifying potential risk factors is strongly emphasized. Efforts to maintain intraoperative normothermia have been shown to be of great importance. Procedures to maintain stable body temperature throughout the perioperative period are presented. The choice of anesthetic technique, in regard to a regional versus general anesthetic approach, is debated widely in the literature. The type of anesthesia to be administered should be assessed on a case-by-case basis, with special consideration given to the health status of the patient, the type of operation being conducted, and the expertise of the anesthesiologist. Specifically addressed in this article are age-related cognitive issues such as postoperative cognitive dysfunction and postoperative delirium. Strategies are suggested for avoiding these pitfalls.

Abstract
Advancements in veterinary medicine have resulted in an increased number of geriatric horses being presented for medical or surgical procedures that require general anesthesia. Due to the physiological changes associated with aging and the likelihood of concurrent disease conditions, the geriatric equine is at an increased risk during anesthesia. The main physiological changes associated with aging, and their impact on anesthesia, are discussed in this review.

Abstract
BACKGROUND The role of open repair in the management of ruptured abdominal aortic aneurysm (RAAA) in patients>80 years old is questioned by the perceived high operative risk of these patients. This issue has been investigated in the present meta-analysis of observational studies. METHODS Studies on open repair of RAAA in patients>80 years old were identified in July 2010. The immediate and intermediate results were expressed as pooled proportions with 95% confidence interval (95% CI). Linear regression and meta-regression were performed to evaluate the impact of variables on the immediate postoperative mortality. RESULTS Pooled analysis of 29 studies showed that the risk of immediate postoperative mortality in patients>80 years old was significantly higher than in younger patients (risk ratio 1.440, 95%CI 1.365-1.519, I2 36.8%, P=0.002; risk difference 19.4%, 95% CI 16.4-22.4%, I2 38.8%, P=0.019). Pooled analysis of 36 studies showed an immediate postoperative mortality rate of 59.2% (95% CI 55.7-62.5, I2 35.62). Immediate postoperative mortality in patients<80 years old positively correlated with that of patients>80 years old (rho: 0.686, P<0.0001). Intermediate survival data of 111 operative survivors were available from six studies, and their pooled survival rates at 1-, 2-, and 3-year were 82.4, 75.6, and 68.7%, respectively. CONCLUSIONS Immediate and intermediate survival rates of patients>80 years old after open repair of RAAA are acceptable. These findings suggest a more confident approach toward emergency repair of RAAA in the very elderly.

Abstract
BACKGROUND The aims of this study were to assess variables associated with survival in patients undergoing ruptured abdominal aortic aneurysm (RAAA) repair and to develop an index other than the aneurysmal diameter to predict rupture potential. METHODS This study included 43 consecutive patients who underwent open surgery for RAAAs. RESULTS The mortality rate was 18.6% (8/43). The ratio between the maximum aneurysmal diameter and the length (along the central axis) from the aneurysmal neck to the point at which the diameter was three-fourth of the maximum aneurysmal diameter was used as an index to predict aneurysmal rupture potential. The index score was 2.7 ± 1.2 in the RAAA and 1.9 ± 0.9 in the EAAA (p = 0.018). For aneurysms of ≤ 6-cm diameter, the index score was 3.0 ± 1.0 in the RAAA and 1.8 ± 0.9 in the EAAA (p = 0.03). All patients in the EAAA except one had an index score of < 2.3 and 6 of the 7 patients with RAAA had a score of > 3. CONCLUSIONS The results suggest that patients with AAA having scores of > 3 are at high risk of rupture. This index would be useful for decision making regarding repair of AAA, especially in the borderline cases.

Abstract
OBJECTIVE The utilization of endovascular abdominal aortic aneurysm repair (EVAR) in suitable patients has resulted in decreased perioperative morbidity and mortality. Octogenarians as a subgroup have been more readily offered EVAR, as it is less invasive, and therefore presumably better tolerated than conventional open aortic repair. The purpose of this study is to investigate periprocedural and late EVAR outcomes in octogenarians compared with patients less than 80 years of age. METHODS From January 2003 to May 2008, 322 patients underwent EVAR. A total of 117 octogenarians were compared with 205 patients less than 80 years of age. A retrospective review of the demographic data, aneurysm details, perioperative morbidity, mortality, and late outcomes were analyzed. RESULTS Octogenarians were significantly more likely to have a history of diabetes mellitus (51% vs 23%; P < .001), coronary artery disease (45% vs 32%; P = .0165), chronic obstructive pulmonary disease (44% vs 30%; P = .0113), and renal insufficiency (57% vs 31%; P < .0001). There were no significant differences in the rates of perioperative myocardial infarction, stroke, death, intestinal, or arterial ischemic complications between the two groups. Octogenarians had a significant higher rate of pulmonary complications (5.1% vs 1%; P < .03) and access-site hematomas (12% vs 2.4%; P = .001) than younger patients. When all significant perioperative morbidity was combined, octogenarians were twice as likely to develop complications following EVAR than younger patients (27.4% vs 11.7%; P = .001). At 5-year follow-up, younger patients were twice as likely to develop type II endoleaks. CONCLUSIONS EVAR can be performed safely and effectively in octogenarians, and the incidence of major complications including myocardial infarction, stroke, and death is unchanged compared with younger patients. However, there is a significantly increased rate of access-site hematomas, pulmonary, and perioperative complications in octogenarians as a whole. Our findings suggest EVAR remains a suitable form of therapy in the elderly group provided there is an appropriate preoperative evaluation and perioperative monitoring following repair.

Abstract
BACKGROUND Endovascular aneurysm repair (EVAR) is commonly used as a minimally invasive technique for repairing infrarenal aortic aneurysms. There have been recent concerns that a subset of high-risk patients experience unfavorable outcomes with this intervention. To determine whether such a high-risk cohort exists and to identify the characteristics of these patients, we analyzed the outcomes of Medicare patients treated with EVAR from 2000-2006. METHODS We identified 66,943 patients who underwent EVAR from Inpatient Medicare database. The overall 30-day mortality was 1.6%. A risk model for perioperative mortality was developed by randomly selecting 44,630 patients; the other one third of the dataset was used to validate the model. The model was deemed reliable (Hosmer-Lemeshow statistics were P = .25 for the development, P = .24 for the validation model) and accurate (c = 0.735 and c = 0.731 for the development and the validation model, respectively). RESULTS In our scoring system, where scores ranged between 1 and 7, the following were identified as significant baseline factors that predict mortality: renal failure with dialysis (score = 7); renal failure without dialysis (score = 3); clinically significant lower extremity ischemia (score = 5); patient age >or=85 years (score = 3), 75-84 years (score = 2), 70-74 years (score = 1); heart failure (score = 3); chronic liver disease (score = 3); female gender (score = 2); neurological disorders (score = 2); chronic pulmonary disease (score = 2); surgeon experience in EVAR <3 procedures (score = 1); and hospital annual volume in EVAR <7 procedures (score = 1). The majority of Medicare patients who were treated (96.6%, n = 64,651) had a score of 9 or less, which correlated with a mortality <5%. Only 3.4% of patients had a mortality >or=5% and 0.8% of patients (n = 509) had a score of 13 or higher, which correlated with a mortality >10%. CONCLUSION We conclude that there is a high-risk cohort of patients that should not be treated with EVAR because of prohibitively high mortality; however, this cohort is small. Our scoring system, which is based on patient and institutional factors, provides criteria that can be easily used by clinicians to quantify perioperative risk for EVAR candidates.

Abstract
OBJECTIVE Open abdominal aortic aneurysm (AAA) repair in octogenarians is considered to have higher risks of mortality and systemic complications compared with younger patients. The purpose of our work is to present our experience with total laparoscopic repair for AAA in this subset of patients. METHODS From February 2002 to February 2008, 29 octogenarian patients underwent total laparoscopic AAA repair. Median age was 82 years (range, 80-85 years). Median aneurysm size was 52 mm (range, 40-85 mm). Disease was classified as American Society of Anesthesiologist (ASA) class II in 12 patients and class III in 17 patients. Ten patients presented with past medical history of myocardial infarct (34.5%). RESULTS We implanted 12 tube grafts and 17 bifurcated grafts. Twenty-six procedures were totally laparoscopic (89.6 %). Median operative time and aortic clamping time were 280 min (range, 160-480 min) and 75 min (range, 22-125 min), respectively. Two patients with juxtarenal AAA underwent suprarenal clamping. Median blood loss was 1100 cc (range, 600-3000 cc). Four patients (13.8%) needed adjunctive vascular procedures because of intraoperative complications. Two patients died in the postoperative course (6.9%). Four patients developed severe systemic non-lethal complications (14.8%, pneumopathies). Mild or moderate systemic complications were observed in 14 patients (51.8%) including transient renal insufficiencies without dialysis (13) and cardiac arrhythmia (1). Postoperative creatinine levels returned to baseline before discharge in all patients. Liquid diet was reintroduced after a median duration of 2 days (range, 1-10 days) and most patients were ambulatory by day four (range, 3-30 days). Median stays in intensive care unit and hospital were 72 hours (range, 12-1368 hours) and 11 days (range, 6-74 days), respectively. Sixteen patients (59.2%) were discharged directly to home with complete recovery. After a median follow-up of 24 months (range, 2-48 months), 23 patients are still alive and regained their baseline status. Four patients died after hospital discharge of non-vascular etiologies. CONCLUSION Total laparoscopic AAA repair is a worthwhile but challenging procedure in octogenarians. Laparoscopy is complementary to open surgery and EVAR in this subset. These results encourage us to offer laparoscopic AAA repair in good surgical risk octogenarians.

Abstract
PURPOSE To define the indications for abdominal aortic aneurysm (AAA) surgery in octogenarians. METHODS We reviewed septuagenarians and octogenarians with a nonspecific AAA diagnosed at our hospital between January, 1990 and June, 2006. RESULTS Among a total 628 patients seen, 306 were in their 70s (group A) and 108 were in their 80s or older (group B). The mortality rate associated with elective surgery was 1.9% in group A and 7.0% in group B. Of the survivors, 12 (5.7%) of 210 in group A and 8 (15.1%) of 53 in group B died within 2 years. Of the patients who did not undergo surgery, 8 of 53 in group A and 8 of 31 in group B had AAAs greater than 6 cm in diameter. The rupture-free rates of AAAs greater than 6 cm in diameter were 64% at 1 year and 0% at 4 years in group A, and 88% at 1 year and 26% at 3 years in group B. The rupture-free rates of AAAs smaller than 6 cm in diameter were 95% at 3 years and 85% at 5 years in group A, and 100% at 5 years in group B. CONCLUSIONS We concluded that AAAs over 6 cm in diameter were an appropriate indication for surgery in octogenarians.

Ann Vasc Surg 2008; 23:159-66. [PMID: 18834704 DOI: 10.1016/j.avsg.2008.05.011] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2007] [Revised: 04/04/2008] [Accepted: 05/08/2008] [Indexed: 11/26/2022]
Abstract
The aim of the study was to determine variables that could be used to predict survival in patients with ruptured abdominal aortic aneurysm (RAAA) and to assess the accuracy of the Glasgow Aneurysm Score (GAS) and the Acute Physiology Chronic Health Evaluation II (APACHE-II). From January 1998 to July 2006, 103 patients underwent operations for RAAA. For each patient, 44 variables were retrospectively recorded in a database. Data were analyzed with univariate and multivariate methods. In the univariate analysis significant predictors of death were hypotension (p=0.001), preexisting peripheral vascular disease (p<0.001), renal insufficiency (p=0.037), chronic obstructive pulmonary disease (p=0.028), level of HCO(3)(-) (p<0.001), intraperitoneal rupture (p=0.001), blood transfused (p<0.001), cardiac complications (p<0.001), and APACHE-II score (p=0.001). Multivariate analysis confirmed statistical significance for coexisting peripheral vascular disease (p<0.001), diastolic blood pressure at admission <60 mm Hg (p=0.039), APACHE-II score >18.5 (p=0.025), HCO(3)(-) <21 mg/dL (p<0.001), and intraperitoneal rupture of the aneurysm (p=0.011) as predictors of death. Results of the study suggested that different factors can be helpful in identifying those patients whose operative risk is prohibitive. APACHE-II, contrary to GAS, is an accurate system to predict postoperative death after repair for RAAA.

Abstract
Increasing numbers of very elderly patients require surgery. Elderly patients are at increased risk of perioperative morbidity and mortality because of the high incidence of co-existing age-related diseases. With greater experience, outcomes from major operations in octogenarians have improved. The increased risks of surgery in the elderly must, however, be individually weighed against the benefits to be gained from symptom relief and improved quality of life.

Abstract
OBJECTIVES This study was undertaken to evaluate predictors and outcomes of octogenarians who underwent abdominal aortic aneurysm repair. DESIGN A prospective observational study. MATERIALS AND METHODS Between January 1st, 1997 and April 15th, 2005, 31 octogenarians were admitted to our Department with the diagnosis of abdominal aortic aneurysm. Mean follow-up time was 53.7+/-27.2 months. All patients were in good clinical condition and represented a selected healthy group of octogenarians. RESULTS The overall perioperative (30-days) mortality rate was 3.1%. The total in-hospital morbidity rate was 22.6%. Overall survival estimates at 48 and 96 months were 81+/-8% and 46+/-21%, respectively. The actuarial freedom from aneurysm-related death at 48 and 96 months was 96+/-4% and 96+/-4%, respectively. The actuarial freedom from aneurysm-unrelated death at 48 and 96 months was 84+/-7% and 48+/-21%. Only coronary artery disease was a significant predictor of survival using multivariate stepwise logistic regression analysis. CONCLUSIONS In this series, AAA surgery was carried out in selected octogenarians without affecting long-term survival.

Abstract
PURPOSE To investigate the early and late outcome after endovascular treatment of abdominal aortic aneurysm (EVAR) in octogenarians compared with patients aged < 80 years. METHODS Patients treated for abdominal aortic aneurysm (AAA) with endovascular repair during the period 1996 to 2004 were collated in the EUROSTAR registry. This study group consisted of 697 patients aged > or = 80 years. Comparison was made with 4198 patients aged < 80 years with regard to the incidence of preoperative characteristics and outcomes of the procedure. RESULTS The proportion of octogenarians treated by EVAR increased during the study period, from 11% in the first year to 18% in the last year. Octogenarians more frequently had cardiac disease, impaired renal function, and pulmonary disease (P = .03, P < .0001 and P = .0001). Thirty-two percent of the octogenarians were recorded unfit for open surgery as opposed to 22% in younger patients (P < .0001); they also had a larger aneurysm diameter (62 vs 58 mm, respectively; P < .0001). The 30-day and in-hospital mortality in octogenarians was 5% vs 2% in the younger group (P < .0001). More device-related complications and systemic complications, including cardiac disease, were noted in octogenarians (7% vs 5% and 19% vs 11%, P = .03 and P < .0001, respectively). This group of patients also had a higher incidence of postoperative hemorrhagic complications, including hematoma (7% vs 3%, P < .0001, respectively). No differences in conversion to open repair and post-EVAR rupture rate were observed. Aneurysm-related mortality and late all-cause mortality was 7% vs 3% and 10% vs 7%, both P < .0001. CONCLUSION Our study supports that EVAR might be considered when treating elderly patients, provided their aneurysms are anatomically suited for the endovascular technique. The risk for late complications compared with open repair may be outweighed by a lower early mortality as well as a shorter time for physical recovery.

Abstract
OBJECTIVES To study early mortality and long-term survival of patients more than 80 years of age having elective open repair for abdominal aortic aneurysm (AAA). DESIGN Retrospective multicenter cohort study. MATERIAL One hundred and five patients, 23 women and 82 men, with a median age of 82 years, operated at three Norwegian hospitals during the period 1983-2002. METHOD Survival analyses were based on data from medical records and the Norwegian Registrar's Office of Births and Deaths. Expected survival was based on mortality rates of the general population, matched by age, sex, and calendar period. Relative survival was calculated as the ratio between the observed and the expected survival. RESULTS During the study period there has been a 10 fold increase in octogenarians treated with open operation for AAA. Early mortality (30-day) for the whole group of patients was 10.5% (95% confidence interval (95% CI) 5.3-18.0), and similar for both genders. The 5-year survival rate was 47% (95% CI 35.9-57.4), and not significantly different from that of a matched group in the general population. Patients aged 84 years or more had a median survival time of 35 months (95% CI 18.5-51.6). CONCLUSION The number of AAA operations in octogenarians has increased considerably during 20 years. Octogenarians operated electively for AAA has higher 30-day mortality as compared to younger patients. Their long-term survival appears similar to a matched control group. The benefit of surgery must be carefully considered against the perioperative risk, especially for the oldest octogenarians.

Abstract
PURPOSE This study was performed using population-based data to determine the changing trends in the techniques for abdominal aortic aneurysm (AAA) repair in the state of Illinois during the past 9 years and to examine the extent to which endovascular aneurysm repair (EVAR) has influenced overall AAA management. METHODS All records of patients who underwent AAA repair (1995 to 2003 inclusive) were retrieved from the Illinois Hospital Association COMPdata database. The outcome as determined by in-hospital mortality was analyzed according to intervention type (open vs EVAR) and indication (elective repair vs ruptured AAA). Data were stratified by age, gender, and hospital type (university vs community setting) and then analyzed using both univariate (chi 2 , t tests) and multivariate (stepwise logistic regression) techniques. RESULTS Between 1995 and 2003, 14,517 patients underwent AAA repair (85% for elective and 15% for ruptured AAA). The average age was 71.4 +/- 7.9 years, and 76% were men. For elective cases, open repair was performed in 86% and EVAR in 14%; and for ruptured cases, open repair in 97% and EVAR in 3%. Elective EVAR was associated with lower in-hospital mortality compared with open repair regardless of age. No differences were observed with age after either type of repair for a ruptured aneurysm. Men had a lower in-hospital mortality compared with women for open repair of both elective and ruptured aneurysms. For EVAR, the mortality of an elective repair was lower in men, but there was no difference after a ruptured AAA. In men, the difference in mortality between elective open repair and EVAR was significant; the type of institution did not influence outcome. Patients >80 years of age had a higher mortality after open repair for both elective and ruptured AAA and after EVAR of a ruptured AAA. The average length of stay was 9.9 days for open elective repair, 13.1 days after open repair of a ruptured AAA, and 3.6 days for EVAR. The independent predictors of higher in-hospital mortality were female gender, age >80 years, diagnosis (ruptured vs open), and procedure (open vs EVAR). The year of the procedure and type of hospital (university vs community) were not predictive of outcome. CONCLUSIONS EVAR has had a significant impact on AAA management in Illinois over a relatively short time period. In this population-based review, EVAR was associated with a significantly decreased in-hospital mortality and length of stay. Octogenarians had higher mortality after both types of repair, with the exception of elective EVAR.

Abstract
OBJECTIVES We analyzed midterm durability of endovascular abdominal aortic aneurysm repair (EVAR) in octogenarians compared with younger patients. METHODS Data for 182 consecutive patients who underwent elective EVAR between 1999 and 2003 were retrospectively reviewed. Forty-nine patients (27%) were 80 years or older (study group [SG]; mean age, 84 years; range, 80-89 years), and 133 patients (73%) were younger (control group [CG]; mean age, 72 years; range, 53-79 years). Chi2 analysis, Fisher exact test, Student t test, and Mann-Whitney U test were used as appropriate to test for intergroup differences. Kaplan-Meier curves, log-rank tests, and multivariate Cox models were used for time-to-event analysis, with P < or =.05 considered significant. RESULTS Mean follow-up was 16 months (range, 1-43 months). Body weight was higher (P <.001), and elevated plasma lipid levels (59% vs 43%; P =.042) and use of nicotine (47% vs 29%; P =.015) more frequent in the octogenarians. Baseline aneurysm size, procedure-related data, and hospital stay were comparable between groups. Aneurysm-related mortality was 0% in the study group and 0.7% in the control group (P =.740). Systemic complications occurred in 22% (SG) versus 11% (CG) (P =.035), owing to a rise in serum creatinine concentration greater than 30% of baseline in 14% in the octogenarian group (vs 5% in the CG; P =.048). Groin lymphoceles developed in 12% (SG) versus 2% (CG; P =.013). Technical success was 96% (SG) versus 98% (CG; P =.408), and clinical success was 86% versus 90% (P =.269). No aneurysm rupture occurred during follow-up, and aneurysm-related adverse events were comparable between groups. The estimated risk for any type of endoleak (2.2; 95% confidence interval [CI], 1.1-4.2; P =.023) or type II endoleak (2.1; 95% CI, 1.0-4.3; P = 0.51) was higher in the study group versus the control group; however, this did not affect secondary procedure rates (SG 16% vs CG 12%; estimated risk, SG vs CG,: 1.5; 95% CI, 0.6-3.6; P = 0.420) or aneurysm remodeling (97.2% combined aneurysm sac stabilization or decrease in both groups; P =.592). Aneurysm enlargement occurred in 2.8% (SG 1 vs CG 4; P =.592). CONCLUSION Elective EVAR in octogenarians appears safe and effective over midterm follow-up, with a temporary decrease in renal function (14%) and postoperative lymphoceles (12%) being the most common postoperative adverse events. Advanced chronologic age is not associated with diminished procedural outcome, clinical success, or postoperative survival, compared with younger age. Because of low perioperative mortality and high procedural success, EVAR may be the preferred approach to abdominal aortic aneurysm treatment in selected elderly patients.

Abstract
OBJECTIVE To report cost related to gained life years after repair of ruptured abdominal aortic aneurysms in patients aged 80 or older. DESIGN A retrospective study based on prospectively registered data. PATIENTS AND METHODS Fifty-three patients aged 80 or older were operated on for ruptured abdominal aortic aneurysm over a 20-year period from 1983 to 2002. Thirty-one (58%) patients had systolic BT <80 mmHg. Operative mortality (<30 days) and long-term survival were studied. The number of life-years gained from the operations was estimated. Based on diagnose related group (DRG) values, the cost of each gained life-year was calculated. RESULTS The operative mortality was 47%. Long-term survival of those patients who survived the operation was similar to that of an age and sex matched population. The 53 operations resulted in 145 gained life-years, which leaves a mean survival of 2.7 years of all the patients and 5.2 years of those who survived the operation. The estimated cost per gained life year was euro6817. CONCLUSIONS The operative mortality of ruptured abdominal aortic aneurysm remains high. The long-term survival of patients who survive the operation is acceptable. The price of each gained life-year is low, as compared to other established treatment modalities. Improved results with endovascular treatment may even decrease the cost per gained life year.

Abstract
OBJECTIVES to investigate whether appropriate selection in patients with infrarenal abdominal aortic aneurysms (AAA) for transfemoral endovascular aneurysm management (TEAM) or open graft replacement (OGR) may decrease in-hospital mortality rates (MR). DESIGN analysis of a clinical series over three periods in an university vascular center. Conclusions of the second period were drawn and prospectively applied in a third period and compared. METHODS during the period 1989-1994 only OGR was available (n=170). In the interval 1995-2000 either OGR or TEAM were carried out (n=454). During the period 01/2001-07/2002 the conclusions concerning selection of treatment modality were drawn and prospectively applied in 132 consecutive patients. MR were recorded and possible significant differences were checked. RESULTS during the first period MR was 6.5%. Overall MR decreased to 3.7% in the second interval. Overall MR of the last period was improved to 1.5% (p<0.05). No patient died after OGR (0% vs 6.5%, p<0.04). As all patients with significant individual risk profiles were treated by TEAM, MR slightly increased (2.9%), but the difference remained insignificant (2.4% in period 2). CONCLUSIONS risk adjusted selection of treatment modality influences the results after OGR significantly, thereby reducing overall MR of elective AAA treatment.

Abstract
BACKGROUND Postoperative mortality rates between 40% and 50% have been invariably reported for the treatment of ruptured abdominal aortic aneurysms (rAAA) over the last 50 years. The aim of this analysis was to investigate which patient subgroups benefit from open surgery and in which subgroups a change of treatment strategies should be considered due to lack of improvement despite optimal patient management. PATIENTS AND METHODS From 1980 to 2002 a total of 230 patients underwent surgery because of a ruptured AAA. The observation period was divided into 3 intervals to achieve an approximately equal distribution of patients. The effect of the observation period and of baseline parameters on mortality rates were investigated. RESULTS Between 1980 and 1990, 72 patients were operated with a mortality rate of 38.9% (n = 28). During the second period (1991-1996) surgery was performed in 72 patients with a mortality rate of 40.3% (n = 29). In the third observation interval (1997-2002) 86 patients underwent surgery with an unvaried high mortality rate of 40.7% (n = 35). By applying a logistic regression model including age, gender, modality of rupture, location of cross-clamping and type of operation, only the modality of rupture and the patient's age, which are uncontrollable by the surgeon, could be shown to have a significant impact. CONCLUSION Summing up these findings, open surgical repair of rAAA only leads to acceptable results when performed in younger patients without supposed comorbidities. Survival appears to be accidental in patients with advanced age and increased prevalence of relevant comorbidities/underlying diseases. Minimally invasive techniques may offer promising treatment options to those patients, as they do in elective interventions.

While elective open abdominal aortic aneurysm (AAA) repair has been shown to be safe in selected octogenarians, very little is known about the role of endovascular AAA exclusion in this high-risk cohort. A retrospective review of our vascular surgical registry from January 1996 to December 2001 revealed 51 octogenarians that underwent infrarenal AAA repair. Since 1999 all octogenarians who presented for AAA repair were evaluated for preferential endovascular stent graft placement. Over the 6-year period, 35 patients underwent standard open repair while 16 patients were found to be anatomic candidates for and were treated with an endovascular stent graft. Hospital and office charts were reviewed to compare the endovascular cohort to the standard open cohort. Factors considered included patient comorbidities, perioperative data, and operative outcomes. Statistical analysis was done using Wilcoxon rank sum test and Fisher exact test. The median age for the entire group was 83 years. There were 11 females in the open group and 1 female in the endovascular group. There were no statistically significant differences in preoperative patient comorbidities between groups. Total mortality for the entire series was 11.8 per cent but this included 5 ruptured AAAs, all of which patients died, and 11 additional AAAs that were symptomatic, of which 1 patient died. Total nonruptured mortality for the entire series was 2.2 per cent (0% for the endo-group and 3.3% for the open group). There were statistically significant differences between the endovascular versus the open groups when comparing aneurysm diameter (5.6 cm vs. 6.2 cm; P = 0.016), estimated blood loss (225 cc vs. 2100 cc; P < 0.001), ICU days (0 vs. 3; P < 0.001), length of hospital stay (2 days vs. 12 days; P < 0.001), and patients with blood transfusions (1 vs. 27; P < 0.001). When comparing postoperative morbidities, 4 of the endovascular patients (25%) and 25 of the open patients (68.6%) had a complication ( P = 0.006). In conclusion, endovascular stent graft treatment of nonruptured infrarenal AAAs in octogenarians led to significantly better outcomes and should probably be considered the preferred treatment whenever anatomically appropriate. Endovascular exclusion of ruptured AAAs may potentially improve future outcomes in this high-risk group.

Abstract
OBJECTIVES In this era of managed health care, third-party payers insist that surgeons minimize hospital stay even after major operations such as aortic surgery. We attempted to identify risk factors that predict prolonged hospital length of stay (LOS) so that realistic expectations can be established for these patients who frequently are at high-risk. METHODS In 1994 a clinical pathway for aortic surgery was implemented at our hospital. Between January 1, 1994, and December 31, 2000, data including identifiable risk factors and LOS were reviewed for 240 patients who underwent elective infrarenal aortic surgery to treat aneurysmal (n = 179) or occlusive (n = 61) disease. Risk factors were analyzed to determine their effect on LOS. Data for patients who underwent endovascular, emergency, or concomitant cardiac surgery were excluded from analysis. RESULTS In-hospital mortality was 0.4% (1 of 240 patients), and morbidity was 18% (44 of 240 patients). Mean LOS was 8.2 +/- 5.7 days for all patients, 6.9 +/- 2.9 days for those without complications, and 13.8 +/- 6.7 days for patients with complications (P <.0001). Factors that predicted prolonged LOS (Kaplan-Meier method) included age older than 75 years (P =.0004), chronic obstructive pulmonary disease (COPD; P =.0351), intraoperative blood loss more than 500 mL (P =.0006), duration of surgery more than 5 hours (P <.0001), wound infection (P =.0311), and postoperative complications overall (P <.0001). Remaining factors associated with prolonged LOS (Cox regression analysis) included age older than 75 years (P =.0050), COPD (P =.0445), and complications overall (P =.0094). CONCLUSION The only identifiable preoperative risk factors that correlated with increasing LOS after elective infrarenal aortic surgery (multivariate analysis) were increasing age and COPD. Third-party payers should allow longer hospitalization for patients older than 75 years and for patients with significant pulmonary disease.

Abstract
OBJECTIVES To predict the costs and effects on life expectancy of an AAA screening programme. METHODS A Markov model was designed to compare the effects of a single screening for a cohort of men 60-65 years with the current no screening strategy. The following health states were distinguished: no AAA, unknown small AAA, follow-up small AAA, unknown large AAA, repaired AAA, rejected large AAA and death. Transition rates between the health states were simulated using cycle times of one year. Transition probabilities were derived from literature and a previous feasibility study. Incremental costs per life year saved were calculated. Sensitivity analyses and discounting for future effects were performed. RESULTS The expected individual AAA costs for non-screening and AAA screening were euro; 196 and euro; 530 respectively. A difference of 3.5 months life expectancy was found in favour of screening leading to euro; 1176/life-year gained. Costs increased as compliance fell. With a discount rate of 4% the costs are euro; 2021/life-year gained. CONCLUSIONS One-time ultrasonographic screening for AAA in men aged 60-65 years appears to be cost-effective.

Abstract
Demographic data indicate an increasing workload of geriatric anaesthesia due to advancing life expectancy and reduced thresholds for high-invasive and high-risk surgery in the elderly. Chronological and biological age may be inconsistent, and the existence of age-related changes may vary between organ systems in the same individual. Age itself is not an illness, but is the most important contributing factor for perioperative complications and adverse outcome when the overall narrowed margins of organ function reserve are transgressed during the perioperative period. Age-related changes in the cardiovascular, pulmonary, nervous, metabolic and locomotive systems that are frequently present in the elderly are discussed with regard to their potential relevance to anaesthesiology. In conclusion, listing current diagnoses will not be sufficient in the assessment of the geriatric patient because age-related changes do not necessarily manifest as pathological entities. Rather, pre-operative examination should focus on determination of individual margins of organ function reserve.

Abstract
Between 1985 and 2000, a total of 871 patients underwent surgical treatment for infrarenal abdominal aortic aneurysm (AAA), including 98 (11.2%) presenting with ruptured abdominal aortic aneurysms (RAAA). An optimized operative protocol was used to treat 77 RAAA starting in January 1989. The main features of the optimized protocol are routine use of intraoperative autotransfusion, revascularization by aortoaortic bypass, absence of systemic heparinization, and use of a collagen-impregnated prosthesis. Intraoperative mortality (IOM) was 3.8%. Postoperative mortality at 1 month (POM1) was 25.9% and postoperative mortality at 3 months (POM3) was 33.7%. Heart failure (p <0.001), hemodynamic shock (p <0.001), and hemorrhage (p = 0.04) were the only complications correlated with POM1. Pneumonia (p = 0.01) and sepsis (p = 0.01) were the only complications correlated with POM3. Isolated acute renal insufficiency was not a significant risk factor for postoperative mortality. Using a cutoff of 75 years, there was a significant age-related difference (p = 0.025) for POM1 but not for IOM and POM3. The findings of this study show that optimizing the operative protocol decreases mortality related to RAAA. The main predictor of POM1 was hemodynamic status while the main predictor of POM3 was infection. Isolated acute renal insufficiency was not a risk factor for mortality. Age should not be considered a contraindication for operative treatment.

Abstract
BACKGROUND The ideal treatment of abdominal aortic aneurysms (AAA) is to operate aneurysms likely to rupture, without exposing other cases to major surgery. The purpose here was to analyse retrospectively the management of AAA in a well-defined geographical region in the 1990's. METHODS 194 new vascular surgical outpatient consultations due to AAA were done to the regional vascular centre during the years 1990, 1992, 1994, 1996 and 1998. Data were collected from case records. Statistics Finland provided causes and dates of death. RESULTS The mean observed annual AAA incidence was 9.0 per 100 000 inhabitants and it rose significantly (33.3%) during the study period. The duration of follow-up varied between 0 and 129 months. The 5/8-year cumulative mortality was 37.3/50.7%. The most common causes of death were AAA-related (31.7%), cardiac (29.1%) or malignancy (19.0%). Twenty-five patients with small AAA were referred to primary health care sector for further follow-up. There were no RAAA (ruptured AAA) deaths in this group. The cumulative 5/8-year mortality was 43.2/49.9%. One hundred patients underwent an elective aneurysm repair with in-hospital mortality of 7.0%. The cumulative 5/8-year mortality was 23.7/35.4%. Twelve patients refused elective treatment. The cumulative 5/8-year mortality was 45.1/ 63.4% and 5/7 deaths were due to RAAA. Twenty-three patients were unfit for elective repair. The cumulative 5/8-year mortality was 87.0%/100% and 5/20 deaths were caused by RAAA. The cumulative 5/8-year RAAA-rate in the patients with AAA more than 5.0 cm in diameter and outside elective aneurysm-repair (n = 23) was 51.9%/100.0%. CONCLUSION The observed incidence of AAA increased during the 1990's. Half of the patients underwent an elective procedure. Patients unfit for surgery died mainly for other reasons than RAAA. Most patients with AAA over 5.5 cm not subjected to elective procedure, died of rupture.

Abstract
BACKGROUND The aim of this study was to audit the outcome of elective open aortic aneurysm repair in a veteran hospital to determine whether age > or =80 years influenced the morbidity or mortality. METHODS All elective abdominal aortic aneurysm (AAA) repaired at Greenslopes Private (Repatriation) Hospital between January 1995 and July 2000 were reviewed. Operative details, premorbid condition, postoperative outcomes as well as length of admission were recorded. Patients were grouped according to age as > or =80 years or <80 years. RESULTS There were 251 open elective AAA (including infrarenal and suprarenal, as well as recurrent AAA) repairs carried out during this period, 64 of which were patients of age > or =80 years. Cardiovascular risks factors did not differ between groups nor did complication rates for patients > or =80 and <80 years of age (19.1 and 19.8%, respectively). Mortality rates were not significantly different between groups (> or =80 years: 6.25%; <80 years: 4.8%; P > 0.6). CONCLUSIONS Age > or =80 years should not be an exclusion criteria when contemplating open elective AAA repair.

Abstract
Abstract
Background
The mortality rate associated with elective aortic aneurysm repair is widely assumed to be in the region of 5 per cent. This figure does not take into consideration the effect of pre-existing risk factors. The Vascular Anaesthesia Society of Great Britain and Ireland conducted a large audit to estimate the in-hospital mortality rate associated with non-emergency infrarenal aortic surgery throughout the British Isles, and to determine the influence of risk factors on mortality rate.
Methods
This was a multicentre, prospective audit of 177 hospitals throughout the UK and Ireland. Data were collected by questionnaire to include all patients undergoing elective or urgent surgery for infrarenal abdominal aortic aneurysm or aortoiliac occlusive disease over 4 months.
Results
Nine hundred and thirty-three patients were recruited into the audit. The overall mortality rate was 7·3 per cent. Factors increasing the risk of death by up to fivefold included age over 74 years, urgent surgery, operation for occlusive disease, limited exercise capacity, a history of severe angina or cardiac failure, the presence of ventricular ectopics and abnormalities suggesting ischaemic heart disease on electrocardiography.
Conclusion
Although the in-hospital mortality rate was similar to previously published figures, the rate increased considerably when commonly encountered risk factors were present.

Abstract
BACKGROUND Although transfemoral endovascular aneurysm management (TEAM) of infrarenal abdominal aortic aneurysms (AAA) is widely performed, open graft replacement is still considered the standard of care. The aim of this study was to investigate whether clear indications for TEAM can be established in patients with significant comorbidities without investigating differences in relative procedure efficacy or durability. METHODS AND RESULTS A propensity score-based analysis of 454 consecutive patients treated electively for AAA from January 1995 through December 2000 was performed. Of those 454 patients, 248 received open surgery and 206 received TEAM. In-hospital mortality rates (MRs) were compared. After adjusting for propensity scores, a Cox proportional hazard model (COX) was employed to test the influence of the respective treatment on postoperative 900-day survival estimates (SEs). Several potential preoperative risk factors were used as covariates. The MR of all patients was 3.7%. Explorative analysis demonstrated that patients treated by TEAM presented with significantly more risk factors. In American Society of Anesthesiologists class IV patients, a significant difference in MR was detected (4.7% for TEAM versus 19.2% for open surgery; P<0.02). After adjusting for the propensity to receive TEAM or open surgery, a regression analysis of survival based on COX revealed predictive influences of impaired kidney (P<0.047) or pulmonary function (P<0.001), increased age (P<0.05), and selection of treatment modality (P<0.002) on SE. CONCLUSIONS TEAM represents a less invasive procedure for AAA therapy in patients with significant preoperative risk factors. Especially in geriatric patients with multiple morbidities, TEAM offers a method of therapy with acceptable MRs and SEs, making active treatment possible in otherwise incurable patients.

Abstract
BACKGROUND Operative repair of ruptured abdominal aortic aneurysm (RAAA) is associated with a high mortality rate but reported figures vary widely. The aim of this study was to estimate the operative mortality of RAAA repair and determine how it has changed over time. METHODS A meta-analysis of all English language literature quoting figures for operative mortality of RAAA repair. RESULTS The pooled estimate for the overall operative mortality rate of RAAA repair from 1955 to 1998 was 48 (95 per cent confidence interval 46 to 50) per cent. Meta-regression analysis of operative mortality over time demonstrated a constant reduction of approximately 3.5 per cent per decade (1954-1997) with an operative mortality rate estimate for the year 2000 of 41 per cent. Seventy-seven studies reported intraoperative mortality but, while this appears to have remained constant over time, there was evidence of the presence of publication bias in the subgroup of papers reporting this outcome. There was no evidence of publication bias for the overall operative mortality outcome. CONCLUSION Contrary to the conclusion of recent studies, this paper demonstrates a gradual reduction with time in the operative mortality rate of RAAA repair.

Abstract
The objective of this report was to analyze the current surgical results of operative treatment in patients suffering ruptured AAA (abdominal aortic aneurysms) and to define those independent predictive factors for mortality. During a period of 2 years, from January 1996 to December 1997, 144 patients operated on for ruptured AAA in 10 hospitals were included in a multicenter retrospective study. Among the collected variables concerning each patient, those with potential relation to surgical mortality were studied: gender, age, diabetes, hypertension, cardiopathy, pulmonary obstructive disease, preoperative renal dysfunction, symptomatic cerebrovascular disease, peripheral vascular disease, hematocrit on admission, preoperative hypotension < 80 mmHg, loss of consciousness, cardiac arrest, aortic aneurysm location (infrarenal versus non-infrarenal), iliac involvement, aneurysm size, type of rupture, left renal vein ligature, ligature of a patent inferior mesenteric artery, place of aortic cross-clamping, type of grafting, exclusion of both hypogastric arteries, venous technical complications, associated surgery, use of cell saver, intraoperative blood loss, and postoperative complications (renal failure, sepsis, coagulopathy, cardiac complications, pulmonary complications, colon ischemia, prosthetic graft complications, and need for reoperation). Those variables with statistical significance in the univariate analysis were introduced into a multivariate logistic regression model to determine the independent predictors of death. From our results we concluded that surgery for ruptured abdominal aortic aneurysms continues to have an excessively high mortality rate. Even though some preoperative variables could be identified as predictors of mortality, an absolute mortality risk has not yet been determined and the decision to negate surgery should be individualized rather than taken on that basis only. Early diagnosis and treatment of symptomatic aneurysms would improve mortality figures and selective screening should be contemplated.

Abstract
OBJECTIVE To analyze the short-term and midterm results of open and endoluminal repair of abdominal aortic aneurysms (AAA) in a large single-center series and specifically in octogenarians. METHODS Between January 1997 and October 2000, 470 consecutive patients underwent elective repair of AAA. Conventional open repair (COR) was performed in 210 patients and endoluminal graft (ELG) repair in 260 patients. Ninety of the patients were 80 years of age or older; of these, 38 underwent COR and 52 ELG repair. RESULTS Patient characteristics and risk factors were similar for both the entire series and the subgroup of patients 80 years or older. The overall complication rate was reduced by 70% or more in the ELG versus the COR groups. The postoperative death rate was similar for the COR and ELG groups in the entire series and lower (but not significantly) in the ELG 80 years or older subgroup versus the COR group. The 36-month rates of freedom from endoleaks, surgical conversion, and secondary intervention were 81%, 98.2%, and 88%, respectively. CONCLUSION The short-term and midterm results of AAA repair by COR or ELG are similar. The death rate associated with this new technique is low and comparable, whereas the complication rate associated with COR in all patients and those 80 years or older in particular is greater and more serious than ELG repair. Long-term results will establish the role of ELG repair of AAA, especially in elderly and high-risk patients.

Abstract
A total of 50 consecutive patients (86% male; median age, 82 years) underwent endovascular repair of abdominal aortic aneurysms (AAAs) ranging from 4.0 to 9.0 cm (median, 5.2 cm). Efficacy of aneurysm exclusion was assessed by angiography, duplex scan, and/or contrast-enhanced computed tomography (CT). Acute technical success was 82%. Access failed in one patient, and immediate conversion to open operation was required in two patients. Improper deployment of the endoluminal graft (ELG) across the renal arteries occurred in one patient. The median operation time, estimated blood loss, packed red blood cells received, contrast volume, and length of intensive care and hospital stay were 128 min, 200 mL, 0.1 unit, 297 mL, 0.9 days, and 3 days, respectively. ELG limb thrombosis was seen in one patient. There were 4 (8%) early endoleaks, and 2 endoleaks were discovered in other patients at 3 and 6 months. Local/vascular and remote/systemic postoperative complications were seen in 13 (26%) and 9 (18%) patients, respectively. At a median follow-up of 11 months (range 2 to 36 months), clinical success was 78%. The aneurysm sac diameter (n = 49) decreased from a preoperative median of 5.2 to 4.7 cm (p = 0.0001). Technical success was high, and results at 11 months were satisfactory. Long-term outcomes require further study.

Abstract
Elective repair of abdominal aortic aneurysms (AAA) in the elderly has conventionally been associated with higher mortality rates than in younger patients, although some authors do not agree with this view. The aim of this study is to look into current results of surgical treatment in elderly patients with nonruptured AAA and to define those factors associated with an increased mortality. Over a period of 2 years (1995-1996), 183 patients aged 75 or older were operated on for nonruptured AAA in 21 hospitals. Their medical records were reviewed and those factors that could be related to death were analyzed. Those variables with statistical significance through univariate analysis were entered into a multivariate logistic regression model to predict mortality. The results showed that surgery for nonruptured AAA in the elderly has a greater mortality rate than that in younger patients, but it is not so great as to deny surgical correction to prevent rupture in selected cases, especially if they are unsuitable for endovascular repair. These patients must first undergo thorough cardiac and renal function evaluation. Selective screening must be considered, so earlier detection and treatment in younger patients can be performed.

Abstract
PURPOSE The aim of this study was to define whether veterans who survived repair of ruptured abdominal aortic aneurysms (AAA) experienced late survival rates similar to those surviving repair of intact AAA. METHODS All veterans undergoing AAA repair in DRGs 110 and 111 during fiscal years 1991-1995 were identified using the Veterans Affairs (VA) Patient Treatment File (PTF). Late mortality was defined using VA administrative databases including the Beneficiary Identification and Record Locator System and PTF. Illness severity and patient complexity were defined using PTF discharge data that were further analyzed by Patient Management Category software. Veterans were followed up to 6 years after AAA repair. RESULTS During the study, 5833 veterans underwent repair of intact AAA while 427 had repair of ruptured AAA in all VA medical centers. Operative mortality was defined as that which occurred within 30 days of surgery or during the same hospitalization as aneurysm repair. For those undergoing repair of intact AAA, operative mortality thus defined was 4.5% (265/5833). Operative mortality was 46% (195/427) after repair of ruptured AAA. Overall mortality (including operative mortality) during 2.62+/-1.61 years follow-up was 22% (1282/5833) with intact AAA versus 61% (260/427) for those with ruptured AAA (P<0.001). Further analysis of survival outcomes was performed in patients who survived AAA repair (i.e., those who were discharged alive and lived 30 days or more after surgery). Of those who initially survived repair of ruptured AAA, 28% (65/232) died during follow-up versus 18% (1017/5568) who initially survived repair of intact AAA (odds ratio 1.74; 95% confidence limits 1.30-2.34; P<0.001). In those initially surviving AAA repair, stepwise logistic regression analysis revealed that increasing age, illness severity, patient complexity, as well as AAA rupture and aortic graft complications were increasingly and independently associated with late mortality. Mean survival time was 1681 days for those who survived >30 days and who were discharged alive after repair of ruptured AAA versus 1821 days for those who initially survived repair of intact AAA (P< 0.001). CONCLUSIONS In addition to higher postoperative mortality rates with ruptured AAA, mortality during follow-up for survivors of AAA repair was also greater for those who survived repair of ruptured AAA. The toll taken by ruptured abdominal aortic aneurysms did not end in the immediate postoperative period.
