Abstract
OBJECTIVE Patients with descending thoracic aortic aneurysms (dTAA) or thoracoabdominal aortic aneurysms (TAAA) often have a variety of medical comorbidities. Those that are deemed acceptable for intervention undergo complicated repairs with good early outcomes. The purpose of this study was to identify variables that were associated with mortality over time. METHODS This was a retrospective review of a prospectively maintained database at our institution from 1983 to 2015. Patients were included if they underwent open or endovascular repair for dTAA or TAAA. Patients were excluded if they were intervened on for traumatic transections. The primary outcome for the study was long-term survival. Secondary outcomes included aortic-related mortality. We had mortality and survival data on all patients. RESULTS A total of 946 patients met our study criteria with a median follow-up of 102.8 months (interquartile range [IQR], 58.9-148.2 months). The median age of the cohort was 71 years (IQR, 63-77 years) with the majority of patients being male (58.1%). The extent of TAAA pathology was as follows: type I (14.2%), type II (21.2%), type III (17.1%), type IV (26.2%), and dTAA (21.2%). A total of 147 patients (15.5%) had a prior dissection. The median diameter of aneurysm was 6.4 cm (IQR, 6.0-7.0 cm). A total of 158 patients (16.7%) underwent endovascular repair over the study period. Variables associated with mortality over time were age, surgical era, acute pathology, dissection, preoperative creatinine, and type IV TAAAs. In addition, experiencing the following complications in the postoperative period was associated with mortality over time: neurological, cardiac, and pulmonary. Aortic-related mortality was 2.1% (n = 20) over the study period. Patients who underwent endovascular repair for acute conditions had better long-term survival when compared with open repair. However, there were no differences in long-term survival between open and endovascular repair for nonacute cases. In addition, repair in the more modern era was associated with improved survival. CONCLUSIONS TAAAs can be repaired with reasonable perioperative mortality rates. Once patients undergo repair of their aneurysm, aortic-related mortality remains low. The addition of endovascular options has dramatically changed management of patients with dTAA and TAAA. Further, endovascular repair was associated with decreased perioperative mortality and significantly increased long-term survival in acute patients. Patients undergoing TAAA repair are generally considered high risk and therefore require extensive long-term follow-up for management of their comorbidities and complications, because these are the main contributors to mortality over time.

Abstract
BACKGROUND Early mortality in ruptured abdominal aneurysm (rAAA) is high, but data on long-term outcome are scarce. The aim of this study was to investigate the long-term outcome in survivors after open surgery for rAAA in well-defined population. METHODS This is a population-based, observational long-term follow-up (beyond 30-day mortality) study of patients surgically treated for rAAA from 2000 through 2014. Long-term survival was analysed using Kaplan-Meier estimates and compared to the general population by analyses of relative survival. RESULTS Out of 178 patients operated for rAAA, 95 patients (55%) either died in the perioperative period, were referred from other hospitals or were lost to follow-up (two patients). Altogether 83 patients were eligible for long-term outcomes: 72 men and 11 women. Estimated median crude survival time was 6.5 years [95% confidence interval (CI) 4.8-8.2]. Men had a median survival of 7.3 years (95% CI 5.1-9.4) versus 5.4 years in females (95% CI 3.5-7.3) (P = 0.082). Reinterventions during follow-up occurred in 31 (37%). Relative survival demonstrated a slightly higher risk of death in the rAAA population compared to the general age- and gender-matched population. Age, but not comorbidities, had a significant influence on long-term survival. CONCLUSION For survivors beyond 30 days after surgery for rAAA, long-term survival compares well to that of an age- and sex-matched population. A high frequency of cardiovascular comorbidities did not seem to affect long-term survival.

Abstract
We investigated factors that affected perioperative, postoperative, and long-term outcomes of patients who underwent open emergency surgical repair of ruptured abdominal aortic aneurysms (RAAA). All patients who underwent open emergency surgical repair from 1990 to 2011 were included (463 patients; 374 [81%] male; mean age 74.7 ± 8.7years). Logistic and Cox regression analyses were performed to explore the association of variables with outcomes. Preoperatively, median (interquartile range) hemoglobin was 11.2 (9.5-12.8) g/dL, and median creatinine level was 140 (112-177) µmol/L. Intraoperatively, the median operative time was 2.25 (2-3) hours, and median estimated blood loss was 1.5 (0.5-3) L; 250 (54%) patients required intraoperative inotropes, and a median of 6 (4-8) units of blood was transfused. Median length of hospital stay was 11 (7-20) days. In-hospital mortality rate was 35.6%, and 5-year mortality was 48%. Age, distance traveled, operation duration, postoperative myocardial infarction (MI), and multi-organ failure (MOF) were predictors of in-hospital mortality and long-term outcome. Additionally, postoperative acute renal failure predicted in-hospital mortality. In patients with RAAA undergoing open surgical repair, the strongest predictors of in-hospital mortality and long-term outcome were postoperative MOF and MI and operative duration.

Abstract
BACKGROUND Long-term survival (LTS) following abdominal aortic aneurysm (AAA) surgery is an outcome that can compare open surgical repair (OSR) and endovascular AAA repair (EVAR) methods. We examined the LTS of persons following successful AAA repair using administrative health data covering the Australian Pharmaceutical Benefits and Medicare Benefits Schemes from 1993 to 2014. METHODS Participants undergoing AAA surgery were identified using procedure codes and the last service provision date used as a proxy mortality marker. LTS and relative survival with control populations in those who survived the initial post-operative period were used to compare OSR and EVAR and estimates between the first and second halves of the study. RESULTS A total of 2060 persons who had undergone AAA repair were identified. Overall median LTS (95% CI) following elective, ruptured OSR and EVAR were 10.4 (9.1-11.0), 8.5 (6.7-10.3) and 9.7 (8.1-11.3) years, respectively. Relative survival rates at 5 and 10 years were 0.89 and 0.7 for OSR and 0.87 and 0.66 for EVAR. LTS rates were similar for OSR and EVAR in age groups 65-84 years (EVAR/OSR range 0.96-1.16); however, EVAR was superior to OSR in persons aged >85 years at 5 years (EVAR/OSR 1.32, log-rank P < 0.05). Relative survival following all techniques of AAA repair showed no significant change over the duration of the study. CONCLUSION LTS following AAA repair was heterogeneous in comparison with control populations and varied with age and procedure. The 5-year LTS following EVAR in persons aged >85 years is superior to OSR. Administrative data can define long-term outcomes following aortic aneurysm surgery and may complement data already collected by surgeons.

Abstract
Recent studies have suggested that endovascular aneurysm repair (EVAR) may reduce the perioperative mortality of ruptured abdominal aortic aneurysm (AAA). Whether EVAR confers any long-term survival advantage over published results for open repair of ruptured AAA has not been established. We conducted a single-center retrospective study over a 10-year period (1994–2004) examining the long-term outcome of patients who have undergone endovascular repair of ruptured AAA. Fifty-four patients underwent endovascular repair of a ruptured AAA. The median age was 75 years (interquartile range 69.5–79.5 years); 42 (78%) patients were male. The perioperative mortality rate was 37%. During a median follow-up of 32 months (range 14–48 months), there were 5 aneurysm-related and 13 non-aneurysm-related deaths. Overall, the 3- and 5-year survival rates were 36% and 26%, respectively. EVAR does not appear to confer any overall survival advantage in the mid- to long term compared with the published results for open repair. The reasons for this remain unclear. Further, larger studies are required to confirm these results.

Abstract
Purpose The aim of this study was to confirm the factors that affect the mortality associated with the open surgical repair of ruptured abdominal aortic aneurysm (rAAA) and to analyze the long-term survival rates. Methods A retrospective review was performed on a prospectively collected database that included 455 consecutive patients who underwent open surgical repair for AAA between January 2001 and December 2012. We divided our analysis into in-hospital and postdischarge periods and analyzed the risk factors that affected the long-term survival of rAAA patients. Results Of the 455 patients who were initially screened, 103 were rAAA patients, and 352 were non-rAAA (nAAA) patients. In the rAAA group, 25 patients (24.2%) died in the hospital and 78 were discharged. Long-term survival was significantly better in the nAAA group (P = 0.001). The 2-, 5-, and 10-year survival rates of the rAAA patients were 87%, 73.4%, and 54.1%, respectively. Age (hazard ratio [HR], 1.05; 95% confidence interval [CI], 1.02–.08; P < 0.001) and aneurysm rupture (HR, 1.96; 95% CI, 1.12–.44; P = 0.01) significantly affected long-term survival. Conclusion Preoperative circulatory failure is the most common cause of death for in-hospital mortality of rAAA patients. After excluding patients who have died during the perioperative period, age is the only factor that affects the survival of rAAA patients.

Abstract
Introduction Cardiac complications are potentially life-threatening following emergency repair of ruptured abdominal aortic aneurysms (rAAA). Our objectives were to describe the incidence, risk factors, cardiac outcomes and mortality associated with elevated cardiac-specific troponin (cTnI) following repair of rAAA. We hypothesized that early post-operative cTnI elevation (>0.15 mcg/L) in rAAA patients would identify a high-risk subgroup for cardiovascular complications and adverse outcomes. Methods This was a retrospective population-based cohort study of all referrals for emergency repair of rAAA in central and northern Alberta, from 1 January 2002 to 31 December 2009. Demographic, clinical, physiologic and laboratory data were extracted, along with cardiac-specific investigations and events in the 72 hours following rAAA repair. Results In total, 55% of patients (n = 77/141) had elevated cTnI, of which 12% (n = 9) had ST segment elevation, 23% (n = 18) had ST segment depression, 5% (n = 4) had other ECG changes, and 61% (n = 47) had no diagnostic ECG changes. Those with positive cTnI were more likely to have coronary artery disease (45.5% vs. 23.4%, P = 0.01) and higher Acute Physiology and Chronic Health Evaluation (APACHE) II scores (24.9 vs. 21.4, n = 0.016). cTnI positive patients were more likely to receive vasoactive support (58.4% vs. 14.1%, P < 0.001), had longer intensive care unit (ICU) lengths of stay (8 (3 to 11) vs. 4 (2 to 9) days, P = 0.02) and higher adjusted in-hospital mortality (40.3% vs. 14.1%; OR 4.23; 95% CI, 1.47 to 12.1; P = 0.007). Conclusions Elevated cTnI early after rAAA repair is an independent predictor for post-operative complications and death.

Abstract
OBJECTIVE Endovascular repair of ruptured abdominal aortic aneurysm (rAAA) is being increasingly performed despite lack of good evidence for its superiority. Other reported studies suffer from patient selection and publication bias with limited follow-up. This study is a single-center propensity score comparing early and midterm outcomes between open surgical repair (OSR) and endovascular repair of rAAA (REVAR). METHODS A retrospective review from January 2001 to November 2010 identified 312 patients who underwent rAAA repairs. Thirty-one patients with antecedent AAA repair and three with incomplete records were excluded, leaving 37 REVARs and 241 OSRs. Propensity score-based matching for sex, age, preoperative hemodynamic status, surgeon's annual AAA volume, and preoperative cardiopulmonary resuscitation was performed in a 1:3 ratio to compare outcomes. Thirty-seven REVARs were matched with 111 OSRs. Late survival was estimated by Kaplan-Meier methods. RESULTS Operative time and blood replacement were higher with OSR. Overall complication rates were similar (54% REVAR vs 66% OSR; P = .23), except for higher incidences of tracheostomies (21% vs 3%; P = .015), myocardial infarction (38% vs 18%; P = .036), and acute tubular necrosis (47% vs 21%; P = .009) with OSR. Operative mortality rates were similar (22% REVAR vs 32% OSR), with an odds ratio of 0.63 for REVAR (95% confidence interval = [0.24, 1.48]; P = .40). No differences in the incidences for secondary interventions for aneurysm- or graft-related complications were noted (22% REVAR vs 22% OSR; P = .99). Kaplan-Meier estimates of 1-, 2-, and 3-year survival rates were also similar (50%, 50%, 42% REVAR vs 54%, 52%, 47% OSR; P = .66). CONCLUSIONS REVAR for rAAA does not seem to conclusively confer either acute or late survival advantages. Routine use of REVAR should be deferred until prospective, randomized trial data become available.

Abstract
PURPOSE This study evaluated the safety and technical and clinical success rates of positioning endovascular endografts (EG) in ruptured abdominal aneurysms. MATERIALS AND METHODS Patients with a ruptured abdominal aortic aneurysm confirmed by contrast-enhanced computed tomography angiography (CTA) were eligible for the analysis. Of 67 patients, 42 (62.7%) were treated with EG. Thirteen patients (30.9%) received an aorto-uni-iliac EG (group A) and 29 a bifurcated EG (group B). Patients were divided for comparative analysis according to the configuration of the EG implanted. RESULTS The primary technical success rate was 100%; the primary clinical success rate was 95% (40/42). There were two intraoperative deaths (4.7%) related to intractable shock. No patient required conversion to open repair. Overall, 12 patients (28.5%) died within 30 days. The in-hospital death rate was 30.9% (13/42). Hospital mortality rate was statistically higher in group A; the type of EG and intensive care unit admission were the only independent predictors of hospital mortality. CONCLUSIONS In our experience, a higher mortality rate was observed for the aorto-uni-iliac configuration; shock at admission was confirmed as the most important factor for postoperative survival.

Abstract
PURPOSE This single-institution retrospective review examines the management of uninfected para-anastomotic aneurysms of the abdominal aorta (PAAA), developed after infrarenal grafting. MATERIALS AND METHODS From October 1979 to November 2005, 31 PAAA were observed in our Department. Twenty-six uninfected PAAA of degenerative etiology, including 24 false and 2 true aneurysms, were candidates for intervention and retrospectively included in our database for management and outcome evaluation. Six (23%) patients were treated as emergencies. Surgery included tube graft interposition (n = 12), new reconstruction (n = 8), and graft removal with extra-anatomic bypass (n = 3). Endovascular management (n = 3) consisted of free-flow tube endografts. RESULTS The mortality rate among the elective and emergency cases was 5% and 66.6%, respectively (p = 0.005). The morbidity rate in elective cases was 57.8%, whereas 75% in emergency cases (p = 0.99). The survival rate during the follow-up was significantly higher for elective cases than for emergency cases. CONCLUSION Uninfected PAAA is a late complication of aortic grafting, tends to evolve silently and is difficult to diagnose. The prevalence is underestimated and increases with time since surgery. The mortality rate is higher among patients treated as an emergency than among patients who undergo elective surgery, therefore, elective treatment and aggressive management in the case of pseudoaneurysm are the keys to obtain a good outcome. Endovascular treatment could reduce mortality. Patients who undergo infrarenal aortic grafting require life-long surveillance after surgery.

Abstract
INTRODUCTION Endovascular repair (EVAR) of acute symptomatic and ruptured abdominal aortic aneurysm (rAAA) can be difficult without a large stock of suitable graft sizes. We report a prospective European multicentre study of a modular aortouniiliac stent-graft. PATIENTS AND METHODS Seven centres, with elective EVAR experience, participated in the study. Sixty-five patients were enrolled from September 2002 - April 2005. Some 45 patients had rAAA and 20 were acutely symptomatic. Their median age was 74 (69-80.3) years, 49 (75%) were men. From a choice of 4 body and 4 limb sizes, stent-grafts were deployed under local or general anaesthesia. RESULTS The endovascular delivery system was introduced and the aneurysm excluded from the circulation in a median of 40 (30-60) minutes from the first incision. The median operative duration was 150 (120-190) mins, blood loss 300 ml (200-800). 33 (51%) operations were performed by a vascular surgeon alone. There were a total of 4 (6%) peri-operative re-interventions, endovascular (n=1), open (n=2) and thrombectomy (n=1). The peri-operative mortality in the rupture group was 40% and 10% in the symptomatic group. CONCLUSIONS Aortouniiliac stent-grafts provide rapid exclusion of rAAA. Suitably trained surgeons can do the operation without a radiologist's support. The mortality rate from rAAA treated with EVAR remains high.

Abstract
OBJECTIVE The objective of this study was to document the health-related quality of life (HRQOL) for patients who survived operative repair of a ruptured abdominal aortic aneurysm (RAAA) and to compare this with a matched group of patients who survived elective operative repair of an abdominal aortic aneurysm (EAAA). METHODS A matched, controlled cohort study of HRQOL was used to compare patients surviving RAAA with an EAAA control group. The study was conducted at two university-affiliated vascular tertiary care referral centers. Survivors of RAAA and EAAA during an 8.5-year period were identified and followed up. The RAAA and EAAA control patients were matched for age, serum creatinine concentration, gender, and duration of follow-up since surgery. HRQOL was measured with the Medical Outcomes Study Short Form-36 Health Survey (SF-36). Scores for the EAAA and RAAA cohorts were also compared with age-corrected SF-36 population scores. RESULTS Of 267 patients operated for RAAA during the study period, 130 (49%) survived to hospital discharge. Death after discharge was documented in 35 patients, leaving a potential study population of 95 RAAA survivors. Thirteen were lost to follow-up, seven refused to participate, and four patients were not able to participate. The SF-36 was completed by 71 RAAA patients (75% of surviving RAAA patients). The 71 RAAA survivors and 189 EAAA control patients were similar for seven of eight domains of the SF-36: Physical Function, Role-Physical, Bodily Pain, General Health, Vitality, Mental Health, and Role-Emotional. There was also no difference in the Physical Health Summary and Mental Health Summary scores. The social function component of the SF-36 demonstrated a statistically significant decline in the EAAA group. Both the EAAA and RAAA SF-36 individual and summary scores compared favorably with population norms that were adjusted only for age. CONCLUSION Long-term survivors of RAAA enjoy a HRQOL that does not differ significantly from EAAA survivors. Scores for both groups compare favorably with population scores adjusted only for age.

Abstract
The purpose of this study was to determine the effects of hiatal and thoracic clamping on postoperative outcome and morbidity and factors affecting mortality and morbidity. The records of 102 patients who had undergone ruptured abdominal aortic aneurysm repair between 1993 and 2005 were evaluated retrospectively. Hiatal clamping and thoracic clamping were performed in 72 patients and 30 patients, respectively. Postoperative complications and survival were evaluated comparatively between the two groups by univariate and multivariate statistical analyses. Overall mortality and hospital mortality rates were 63 (61.8%) and 24 (23.5%) patients, respectively; and there was no difference between the two groups. Postoperative respiratory complications, gastrointestinal complications, and blood requirement were higher in the thoracic clamping group. Preoperative shock and renal ischemia time (>30 min) were found to be significant predictors of hospital mortality. Postoperative renal failure was the only independent postoperative predictor of mortality. In the follow-up period, cardiac event was an independent predictor of late mortality. If hospital mortalities were excluded, 5-year and 10-year cumulative survivals were 57.82 +/- 5.85% and 38.16 +/- 6.97%, respectively. Cross-clamp level did not have a significant effect on long-term survival. Although both thoracic and hiatal clamping had no effect on mortality, postoperative respiratory complications, blood requirement, and intestinal ischemia were more pronounced in patients operated with thoracic clamping. Hiatal clamping is preferable for a safe postoperative period.

Abstract
OBJECTIVE The purpose of this study was to evaluate the results of open repair for ruptured descending thoracic and thoracoabdominal aortic aneurysm (RDTAA). METHODS A retrospective review identified 41 consecutive cases of open surgical repair in 40 patients presenting with nontraumatic, atherosclerotic RDTAA from 1996 to 2006. Patients with traumatic injuries or complicated dissections were excluded. Patient characteristics and preoperative, intraoperative, and postoperative variables were collected from the medical record. Univariate and logistic regression were used to identify factors contributing to mortality and morbidity in these patients. RESULTS The operative mortality rate was 26.8% (11/41). All but two deaths occurred within 24 hours of operation; seven were intraoperative. Overall actuarial survival rates at 1 and 2 years were 53.7% and 47.1%, respectively. For those who survived to hospital discharge, the respective numbers were 73.3% and 64.4%. Intraoperative hypotension and blood transfusion requirements were independent predictors of perioperative death. Octogenarians had a mortality rate equivalent to that of the younger population (25% vs 27.6%; not significant). There was a strong trend toward an improved outcome in the latter part (2003-2006) compared with the first part (1995-2002; 13.6% vs 42.1%, respectively; P = .075). CONCLUSIONS Direct open repair for RDTAA can be achieved with acceptable mortality and morbidity rates even in elderly patients. Improved outcome can be expected with increased volume and experience. This series should help establish a reference against which the results of endovascular endeavors and hybrid procedures could be compared.

Abstract
Our aim was to assess the utility of surgery for ruptured abdominal aortic aneurysm (RAAA) using the number of quality-adjusted life years (QALYs) in a retrospective study with cross-sectional quality-of-life (QoL) evaluation. During a 7-year period up to 2002, 242 of 269 (90%) patients with RAAA underwent surgery. Survivors were sent the EQ-5D self-administered questionnaire to assess their long-term outcome. EQ-5D single index values were calculated for each survivor and combined with age- and sex-adjusted Finnish life tables to obtain QALY estimates. Total hospital mortality (90-day) and operative mortality (30-day) were 140 of 269 (52.0%) and 106 of 242 (43.8%), respectively. Of the 129 surviving patients, 111 were available for QoL evaluation. The response rate was 85%. The mean (range) number of QALYs after RAAA was 4.1 (0-30.9) for all and 8.5 (0.2-30.9) for hospital survivors. Young age and low Glasgow Aneurysm Score were associated with a high number of QALYs irrespective of the statistical method used for analysis. Successful repair of RAAA was able to lend considerable benefit as measured by QALYs.

Abstract
OBJECTIVE To examine late reintervention rates for aortic graft-related events and new aortoiliac disease after open abdominal aortic aneurysm (AAA) repair in an Australian population. METHODS Interrogation of a prospective computerized database identified 1256 consecutive patients (1058 men, 198 women; median age, 70 years; range, 40 to 97 years) who survived open repair of nonruptured (n = 957, group I) and ruptured (n = 299, group II) infrarenal AAA in a single institution between January 1, 1982 and December 31, 2003. Median (range) follow-up was 41 (1 to 261) months for group I and 30 (1 to 243) months for group II. RESULTS In group I, 33 patients (3.4%) underwent 38 late reinterventions: 20 patients (2.1%) for aortic graft-related events at a median (range) interval of 36 (1 to 94) months after the index AAA repair, with a 30-day mortality rate of 15%; and 13 patients (1.4%) for new aortoiliac disease at a median (range) interval of 33 (3 to 207) months, with 30-day mortality of 8%. In group II, 15 patients (5%) underwent 16 late reinterventions: 10 patients (3.3%) for aortic graft-related events at a median (range) interval of 5 (2 to 112) months, with a 30-day mortality of 10%; and five patients (1.7%) for new aortoiliac disease at a median (range) interval of 67 (39-105) months, with a 30-day mortality of 40%. There was no significant difference in the late reintervention rate between the groups: group I, 33 (3.4%) of 957 vs group II, 15 (5%) of 299 (P = .23). For all patients, the estimated survival at 1, 3, 5 and 10-years was 90%, 79.4%, 66.4%, and 31.6%, respectively; estimated survival free from reintervention at 1, 3, 5 and 10-years was 98.7%, 97.1%, 95.1%, and 91.9%, respectively. CONCLUSIONS These data demonstrate, for the first time, that open AAA repair has excellent long-term durability in an Australian population and the results compare favorably with previous reports from North America and Europe. These data represent an important benchmark for comparison of the results of endovascular AAA repair in this patient population.

Abstract
Cardiopulmonary complication after ruptured abdominal aortic aneurysm (rAAA) repair is an important cause of mortality. Early tracheostomy promotes patient recovery from respiratory morbidities. A policy of routine immediate tracheostomy was adopted in 1999 at our institution. This study investigates the trend of hospital mortality of rAAA patients over 12 years with particular reference to immediate tracheostomy. Consecutive rAAA patients operated during 1993-2004 were divided into two groups (first group, 1993-1998; second group, 1999-2002). Intra- and postoperative care was the same for all patients except that immediate tracheostomy was performed routinely in the second group and only selectively in the first. Hospital mortality of the two groups was examined. Patient characteristics, biochemical parameters, aneurysm feature, operative details, and clinical outcomes of the two groups (excluding 48 hr perioperative mortalities) were compared to identify prognostic factors of hospital mortality. Sixty-three patients were operated during the study period. The overall hospital mortality for the first and second groups was 62.5% (20/32) and 22.6% (7/31) (p=0.001), respectively. Excluding the 48 hr mortalities, 57.1% (12, n=21) of patients in the first group and 85.7% (24, n=28) of those in the second group survived to be discharged from hospital (p=0.048). The pre-, intra-, and postoperative parameters were comparable between the two groups. Immediate tracheostomy was performed for all patients in the second group and only 52.4% (11) in the first group. Male gender, high creatinine level on presentation, postoperation cardiac morbidity, renal failure, and bowel ischemia were found to be associated with a higher mortality. Immediate tracheostomy is a significant factor associated with improved survival. In conclusion, a significant improvement of rAAA patients' in-hospital mortality was achieved during the study period. Tracheostomy performed immediately following rAAA repair is associated with better hospital survival.

Abstract
OBJECTIVE To determine the operative mortality of ruptured abdominal aortic aneurysm (RAAA) in The Netherlands. DESIGN Retrospective population-based study of nation-wide in-hospital mortality of RAAA repair. METHODS Data were obtained from a national registry for medical diagnosis and procedures. In-hospital mortality of RAAA repair, defined as death during hospital admission irrespective of the cause of death, was determined in the period 1991-2000. Variables of potential influence on in-hospital mortality, including age, gender, date of surgery and hospital type (0-399 beds, > or =400 beds or university hospitals) were studied in a multivariate analysis. RESULTS The overall in-hospital mortality of RAAA repair in 5593 patients in the 10-year period was 41% (95% confidence interval: 40-42%). In the multivariate analysis, age and hospital type were the most important independent predictors for in-hospital mortality. Gender, year and season of surgery could not be identified as significant risk factors. CONCLUSIONS Over a recent decade, in-hospital mortality of RAAA repair remained unchanged at 41%. Age and hospital class were the most important independent risk factors.

Abstract
OBJECTIVE The primary objective of this study was to develop a simulation model to assess the cost-effectiveness of different screening strategies for abdominal aortic aneurysms (AAAs) in men. METHODS A systematic review of the literature was conducted for different screening strategies in terms of age (60, 65, or 70 years) and risk profiles (all men or specific high-risk groups) of the screened population, and rescreening after 5 or 10 years. These data were analyzed in a Markov simulation cohort model. RESULTS The cost per life year gained for different screening strategies ranged from US 8,309 dollars to US 14,084 dollars and was estimated at US 10,474 dollars when 65-year-old men were screened once. Screening 60-year-old men was equally cost-effective, with the advantage of more life years gained. We demonstrated a trade-off between high prevalence of AAA and lower life expectancy, eliminating the expected benefits of screening high-risk groups such as smokers (US 10,695 dollars) or cardiovascular patients (US 10,392 dollars). Assuming general population utility resulted in a cost per quality-adjusted life year (QALY) gained of US 13,900 dollars, whereas a hypothetical 5% reduction in utility among men with a screening-detected AAA raised the cost per QALY gained to US 75,100 dollars. CONCLUSION This Markov model, which was based on a systematic review of the literature, supplied information on the estimated cost-effectiveness of different screening strategies. Screening men for AAA may be cost-effective in the long-term. Different screening strategies and quality-of-life effects related to screening for AAA need to be evaluated in future clinical studies.

Abstract
In-hospital outcomes associated with abdominal aortic aneurysm (AAA) repair are well described. However, little is known about post-discharge readmission rates, lengths of stay, associated mortality, and costs. We examined 206 consecutive patients who underwent AAA repair at two American hospitals between 1998 and 2000. Index hospitalization and 6-month readmission data were extracted from a resource and cost accounting system used by both hospitals. Among the 206 patients, 183 survived until discharge (mortality rate 11.2%). Among the surviving patients, 38 (21.0%) were readmitted within 6 months. Half of the readmissions occurred within two weeks of discharge, with patients presenting with a diverse array of complications. Nonelective repair and diabetes mellitus were independent predictors of hospital readmission (OR = 2.83, 95% CI = 1.25-6.40, p = 0.01; OR = 6.60, 95% CI = 1.02-42.4, p = 0.047, respectively). For each readmission, the mean length of stay was 10.7 +/- 2.5 days and the mean cost was dollar 13,397 +/- 3,381. The cumulative number of hospital days during the 6 months post-discharge was 17.7 +/- 3.5 days for each readmitted patient and the mean per-patient total cost was dollar 23,262 +/- 5,478. The mortality rate among readmitted patients was 13.2%. Overall, readmissions following AAA repair accounted for a cost >50% over and above the cost of the readmitted patients' index hospitalization. Hospital readmissions are common during the 6 months following AAA repair. Patients who are readmitted experience long lengths of stay and high mortality rates, and their care incurs high costs.

Abstract
OBJECTIVE The primary aim of ultrasound follow-up after aorto-iliac prosthetic reconstruction is to correct false aneurysms before rupture occurs. We investigated whether follow-up improves the life expectancy of patients and sought to identify the most cost-effective follow-up strategy. DESIGN OF THE STUDY A Monte Carlo Markov decision model was constructed. The occurrence of false aneurysms was modelled as a time-dependent process for each anastomotic site, based on published series. Using this model, the impact of various follow-up strategies was investigated for three types of prostheses, aorto-distal tube, aorto-bi-iliac, and aorto-bi-femoral prostheses. Main outcome measures were discounted quality adjusted life years (dQALYs), discounted costs, and (discounted) cost-effectiveness (CE) ratios. RESULTS Follow-up of patients with aorto-distal tube and aorto-bifemoral prostheses did not result in an improvement life expectancy and was not cost-effective, QALYs 7.53 and 7.62 years, respectively. The results for aorto-distal tube and aorto-bifemoral prostheses were not sensitive to any variation in the model parameters. In the base case analysis, the life expectancy of patients with aorto-bi-iliac prostheses was 7.50 QALYs (95% confidence interval 7.46-7.54) whether or not they underwent routine follow-up. However, patients aged 54 years or younger gained 0.11 QALYs with annual follow-up (p<0.05). The most cost-effective strategy was annual follow-up that starts 10 years after the initial operation, and continues up to 30 years after surgery (4600 Euro; CE ratio 21,000 Euro per QALY). When perioperative mortality of elective reconstruction of false aneurysms is 2% or lower (e.g. when endovascular treatment is used), a small improvement is observed (7.56 vs. 7.50 QALYs; p<0.05; CE ratio 35,000 Euro per QALY). CONCLUSIONS Annual follow-up of aorto-bi-iliac prostheses should be restricted to patients aged 54 or younger and not start before 10 years after surgery. The same strategy can only be considered for older patients if mortality for secondary intervention is lower than 2%. Since patients with aorto-distal tube and aorto-bi-femoral prostheses do not benefit from follow-up for the detection of false aneurysms, this practice should be discouraged in these patient groups.

Abstract
OBJECTIVES Quality of life as an endpoint of surgery and the long-term prognosis for patients who have survived surgery for a ruptured abdominal aortic aneurysm (RAAA) is not well-documented. PATIENTS AND METHODS The records of all patients from 1993 to 2000 who underwent resection of RAAA were reviewed. Survival data were calculated from direct contact with the patients or follow-up records. All patients who were alive at the time of our study were invited to participate in follow-up investigations. They received the internationally comparable WHO-QOL-BREF-test. RESULTS In a period of 7 years, 80 patients underwent surgery for RAAA. The average follow-up time was 5.1 years (1-7.9 years). Our data show that 51% of our patients died within 6 months postoperatively because of the complications of the aortic rupture (in-hospital mortality 39%). Patients who survived the first 6 months after surgery died for the same reasons as the normal population. However, patients who were younger than 75 at the time of RAAA had a higher relative survival rate than a matched sample of the population. There was no significant difference in the quality of life between the study group and the general population. CONCLUSIONS RAAA survivors had no difference in long-term survival as compared to the general population and also had very few long-term complications. The WHOQOL-BREF-test suggests that the quality of life of survivors of RAAA is similar to the general population.

Abstract
OBJECTIVES To evaluate short- and long-term outcome after open repair for ruptured and non-ruptured abdominal aortic aneurysm (AAA) with special emphasis on the difference between men and women. DESIGN Single center retrospective study. Time and cause of death were determined from hospital charts, the National Bureau of Statistics and the Department for National Health and Welfare. Materials. Eight hundred and forty-six patients were followed-up, 597 were operated on for non-ruptured and 249 for ruptured aneurysms. METHODS Case fatality was analyzed by multiple logistic regression considering year of surgery, age at surgery, and gender as covariates. The mortality rate for patients surviving 60 days after surgery was compared with the mortality in the general population by calculating the standardised mortality ratio (SMR). Mortality was also stratified according to gender and type of surgery. RESULTS The SMR for patients surviving 60 days after surgery was significantly increased. SMR was significantly higher for women than for men. There was no statistically significant difference in SMR between patients operated for rupture compared to those operated for non-ruptured aneurysms. CONCLUSIONS Women with AAA have a poorer outcome than women in the general population. This finding may relate to the large number of risk factors present in this patient sub-group.

Abstract
OBJECTIVE Repair of thoracovisceral aortic aneurysms (TVAA) after previous open repair of an infrarenal abdominal aortic aneurysm (AAA) poses significant challenges. We sought to better characterize such recurrent aneurysms and to evaluate their operative outcome. METHODS We reviewed the records and radiographs of 49 patients who underwent repair of TVAAs between 1988 and 2002 after previous repair of an AAA. Visceral artery reconstructions were completed with combinations of beveled anastomoses, inclusion patches, and side arm grafts. In 14 patients visceral endarterectomy was required to treat associated occlusive disease. Sixteen patients had cerebrospinal fluid drainage, and 10 patients had distal perfusion during cross-clamping. RESULTS Patient mean age was 72 years, and 80% were men. Fifty-one percent of patients had symptomatic disease, and average TVAA diameter was 6.2 cm. Mean time between AAA and TVAA repair was 77 months. Twenty-six percent of aneurysms were restricted to the lower visceral aortic segment, 35% extended to the diaphragm, another 35% extended to the distal or middle thoracic aorta, and 4% involved the entire remaining visceral and thoracic aorta. The 30-day operative mortality rate was 4.1% in patients with nonruptured aneurysms and 50% in patients with ruptured aneurysms, for an overall mortality rate of 8.2%. Fifteen patients (30.6%) had major morbidity, including paresis in two patients and dialysis-dependent renal failure in five patients. At late follow-up, three patients required further aortic operations to treat additional aneurysms, and four patients had fatal aortic ruptures. Two-year and 5-year cumulative survival rates were 61% (+/-7.5%) and 37% (+/-7.8%), respectively. At univariate analysis, operative blood loss was the sole significant predictor of major morbidity (P <.023), and rupture (P <.030, P <.0001) and aneurysm extent (P <.0007, P <.0001) correlated with both operative death and long-term survival. Only aneurysm extent (P <.010, relative risk 37.3) remained a significant predictor of long-term survival at multivariate analysis. CONCLUSION Elective repair of TVAAs after previous AAA repair can be performed with an acceptable level of operative mortality, though with considerable operative morbidity. Limited long-term survival mandates careful patient selection, and the high mortality associated with ruptured TVAA underscores the need for post-AAA surveillance.

Abstract
BACKGROUND This report describes our preliminary experience in endovascular management of 25 ruptured abdominal aortic aneurysms (rAAAs). METHODS In the past 3 years we treated 46 patients who had rAAA, and 25 (54.3%) were treated with an endovascular approach. Patients' mean age was 76 +/- 9 years. The diagnosis was confirmed by computed tomographic angiography in 23 patients (92%). Mean aneurysm diameter was 73 +/- 17 mm. We used an infrarenal bifurcated device in 17 patients (68%), a suprarenal bifurcated in four patients (16%), and an aortomonoiliac graft in four patients (16%). Overall, nine patients (36%) required intensive care. Every patient underwent radiologic follow-up according to the Eurostar register, with concomitant evaluation of the D-dimer level (cut-off <200 microg/L) as a biological marker for endoleaks. RESULTS The primary technical success rate was 100%. Overall in-hospital mortality rate was 20%. Mean hospitalization was 7 days (range, 3-30), and mean follow-up was 7 months. One occlusion (4%) of the iliac limb and two type II endoleaks (8%) occurred. The mean D-dimer level in type I endoleak was 1045 microg/L (range, 459-2021). CONCLUSIONS In our experience, endovascular management of rAAA is feasible and safe and produces better results than conventional surgery, provided the morphology is suitable and the procedure is carried out by an experienced endovascular team.

Abstract
Endovascular aneurysm repair (EVAR) is a controversial technique, which remains the subject of a number of prospective randomised trials. Although questions remain regarding its long-term durability objective evidence exists which demonstrates its reduced physiological impact compared with conventional open repair. If this technique could be used in patients with ruptured abdominal aortic aneurysm (AAA) it may reduce the high peri-operative mortality. A review of the literature identified a limited experience with EVAR of ruptured AAA. Only a small number of case series with selected patients exist. The majority of patients were haemodynamically stable. However, the selective use of aortic occlusion balloons allowed successful endovascular management in a small number of unstable cases. All investigators had access to an "off the shelf" endovascular stent-graft (EVG). Per-operative mortality ranged from 9 to 45% and may reflect increasing experience and patient selection. A number of patients who underwent successful EVAR were turned down for open repair. A number of important lessons have been learned from these studies but questions remain regarding patient suitability and staffing issues. If these difficulties can be surmounted then the technique may offer an alternative to open repair.

Abstract
OBJECTIVE To assess the cost effectiveness of ultrasound screening for abdominal aortic aneurysms. DESIGN Primary analysis: four year cost effectiveness analysis based directly on results from a randomised controlled trial in which patients were individually allocated to invitation to ultrasound screening (intervention) or to a control group not offered screening. Secondary analysis: projection of the data, based on conservative assumptions, to indicate likely cost effectiveness at 10 years. SETTING Four centres in the United Kingdom. Screening delivered in primary care settings with follow up and surgery offered in the main hospitals Participants: Population based sample of 67 800 men aged 65-74 years. MAIN OUTCOME MEASURES Mortality from and costs (screening, follow up, elective and emergency surgery) related to abdominal aortic aneurysm; cost per life year gained. RESULTS Over four years there were 47 fewer deaths related to abdominal aortic aneurysms in the screening group than in the control group, but the additional costs incurred were pound 2.2m. After adjustment for censoring and discounted at 6% the mean additional cost of the screening programme was pound 63.39 ($97.77, euro;100.48) (95% confidence interval pound 53.31 to pound 73.48) per patient. The hazard ratio for abdominal aortic aneurysm was 0.58 (0.42 to 0.78). Over four years the mean incremental cost effectiveness ratio for screening was pound 28 400 ( pound 15 000 to pound 146 000) per life year gained, equivalent to about pound 36 000 per quality adjusted life year. After 10 years this figure is estimated to fall to around pound 8000 per life year gained. CONCLUSIONS Even at four years the cost effectiveness of screening for abdominal aortic aneurysms is at the margin of acceptability according to current NHS thresholds. Over a longer period the cost effectiveness will improve substantially, the predicted ratio at 10 years falling to around a quarter of the four year figure.

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
PURPOSE This study reviewed the long-term outcome of patients who underwent open repair of infrarenal abdominal aortic aneurysms (AAAs). METHODS A retrospective study of 208 patients (188 men and 20 women) with a mean age of 65.6 years who survived elective or emergency open repair of an infrarenal AAA was conducted at a university referral hospital. Main outcome measures included late graft-related complications, survival free from any reintervention, survival free from any vascular reintervention, and overall survival rates. RESULTS Late graft-related complications occurred in 32 patients (15.4%). A proximal para-anastomotic pseudoaneurysm developed in six patients (2.9%), and a distal pseudoaneurysm developed in 18 patients (8.7%); in seven of these cases (3.4%), it was bilateral or recurrent. A graft limb occlusion occurred in 11 patients (5.3%). These complications required 37 surgical or other invasive procedures in 27 patients (13.0%). Thirty-one vascular and/or endovascular reoperations were performed. The 5-year, 10-year, and 15-year survival free from any reintervention rates were 91.5%, 86.2%, and 72.0%, respectively. At the same intervals, the survival free from any vascular reintervention rates were 93.8%, 88.5%, and 73.9%, respectively, and the overall survival rates were 66.8%, 39.4%, and 18.0%, respectively. Complications associated with a ruptured femoral artery pseudoaneurysm, a ruptured aortic pseudoaneurysm, an aortoduodenal fistula, and the elective repair of a femoral pseudoaneurysm were the graft-related causes of death, which occurred in four patients (1.9%). Age (P <.0001) and chronic obstructive pulmonary disease (P =.002) were shown by means of multivariate analysis to be predictive of poor survival outcome, and chronic obstructive pulmonary disease (P =.02) and lower limb ischemia (P =.04) were shown to be associated with an increased need for vascular reinterventions to treat graft-related complications. CONCLUSION Open repair of infrarenal AAAs can achieve satisfactory 15-year follow-up rates of survival free from reintervention for any graft-related complications, suggesting that surgery should still be considered the procedure of choice for infrarenal AAAs, at least in patients who are fit for surgery.

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 Infected aortic aneurysms are rare, difficult to treat, and associated with significant morbidity. The purpose of this study was to review the management and results of patients with infected aortic aneurysms and identify clinical variables associated with poor outcome. METHODS The clinical data and early and late outcomes of 43 patients treated for infected aortic aneurysms during a 25-year period (1976-2000) were reviewed. Variables were correlated with risk of aneurysm-related death and vascular complications, defined as organ or limb ischemia, graft infection or occlusion, and anastomotic or recurrent aneurysm. RESULTS Infected aneurysms were infrarenal in only 40% of cases. Seventy percent of patients were immunocompromised hosts. Ninety-three percent had symptoms, and 53% had ruptured aneurysms. Surgical treatment was in situ aortic grafting (35) and extra-anatomic bypass (6). Operative mortality was 21% (9/42). Early vascular complications included ischemic colitis (3), anastomotic disruption (1), peripheral embolism (1), paraplegia (1), and monoparesis (1). Late vascular complications included graft infection (2), recurrent aneurysm (2), limb ischemia (1), and limb occlusion (1). Mean follow-up was 4.3 years. Cumulative survival rates at 1 year and 5 years were 82% and 50%, respectively, significantly lower than survival rates for the general population (96% and 81%) and for the noninfected aortic aneurysm cohort (91% and 69%) at same intervals. Rate of survival free of late graft-related complications was 90% at 1 year and 5 years, similar to that reported for patients who had repair of noninfected abdominal aortic aneurysms (97% and 92%). Variables associated with increased risk of aneurysm-related death included extensive periaortic infection, female sex, Staphylococcus aureus infection, aneurysm rupture, and suprarenal aneurysm location (P <.05). For risk of vascular complications, extensive periaortic infection, female sex, leukocytosis, and hemodynamic instability were positively associated (P <.05). CONCLUSION Infected aortic aneurysms have an aggressive presentation and a complicated early outcome. However, late outcome is surprisingly favorable, with no aneurysm-related deaths and a low graft-related complication rate, similar to standard aneurysm repair. In situ aortic grafting is a safe and durable option in most patients.

Abstract
BACKGROUND The literature reporting the long-term survival following surgery for abdominal aortic aneurysm (AAA) tends to be confusing. As a result, many clinicians looking after patients with AAA may be uncertain about the five-year survival of a given patient. This is in marked contrast to the situation for patients with malignant disease. With the current interest in population screening and endoluminal stenting for AAA, an understanding of long-term survival is increasingly important. METHODS Thirty two publications in the English language over the last 20 years, containing data pertaining to five-year survival following routine elective surgery for AAA in unselected patients, were identified using Medline searches. RESULTS AND CONCLUSIONS A range of important methodological differences were noted. The mean five-year crude survival was about 70% while the expected survival of a matched population was close to 80%. Survival was further reduced by about 10% in cases with significant coronary heart disease. Age alone is not a predictor of long-term relative survival with octogenarians who survive beyond 30 days surviving longer than an age-matched population.

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.

Abstract
BACKGROUND Cardiovascular disease such as coronary artery disease is a major cause of late death after repair of abdominal aortic aneurysm (AAA). But risk factors are not well known. So, we investigated the incidence of cardiovascular events after surgery and examined the prognostic factors. STUDY DESIGN We retrospectively reviewed 270 patients who underwent elective surgery for AAA from 1985 to 1995. Kaplan-Meier survival analysis was used to estimate survival rates and the probability of coronary, cerebrovascular, and cardiovascular events. The risk factors for each endpoint were investigated using multivariate analysis. RESULTS The overall survival rate was 87.3% at 3 years, 76.4% at 5 years, and 52.3% at 10 years. Current cigarette use, renal insufficiency, advanced age (> or = 70 years old), and higher plasma fibrinogen level (> or = 300 mg/dL) were significant factors influencing survival. The probability of a coronary event was 4.9% at 3 years, 7.1% at 5 years, and 20.7% at 10 years. Plasma fibrinogen level and cerebrovascular disease were significant prognostic factors for coronary events. The probability of a cerebrovascular event was 5.3% at 3 years, 7.6% at 5 years, and 18.0% at 10 years. No significant prognostic factors for cerebrovascular events existed. The probability of a cardiovascular event was 10.3% at 3 years, 14.9% at 5 years, and 33.6% at 10 years. Plasma fibrinogen level was a significant risk factor for cardiovascular events. But the presence of coronary artery disease did not affect survival or the incidence of coronary, cerebrovascular, or cardiovascular events. CONCLUSIONS Plasma fibrinogen level is an independent risk factor of future coronary events after surgery for AAA, and the increased risk of coronary artery events contributes to the impaired survival. Patients with higher plasma fibrinogen level need careful surveillance for cardiovascular disease after surgery.

Abstract
The aim of the study is a retrospective review of clinical presentation and management of paraanastomotic aneurysms of the abdominal aorta (PAAA) surgically treated in our Department. From January 1984 to December 1998, 2183 aortic prosthetic grafts were implanted. During the same period, 24 patients were treated for PAAA, 19 false and five true aneurysms. Symptoms were present in 10 patients. Surgical management included tube grafting interposition (14), aortobifemoral bypass (2), graft removal with extraanatomic bypass (2) and with in situ revascularization by arterial homograft (4). Nine patients died during operation or in the early postoperative period, six died during follow-up. Mortality in symptomatic patients was 70%, while in asymptomatic group was 14% (P=0.01). Rupture of false PAAA was very frequent (47% of cases). PAAA are infrequent complications of proximal aortic graft revascularization and tend to be asymptomatic until rupture occurs. The incidence of mortality is very different in asymptomatic versus symptomatic group; rupture is particularly frequent in false PAAA, which must soon undergo surgery when diagnosed. Since PAAA may develop at any time after surgery, their incidence increase in relationship with the length of postoperative interval: therefore, all patients submitted to abdominal graft revascularization need a lifetime surveillance program.

Abstract
PURPOSE To report our initial experience with endovascular grafting to treat ruptured abdominal aortic aneurysms (AAAs). METHODS Three consecutive patients with severe comorbid illnesses and symptoms of aneurysm rupture and hemodynamic instability were treated with aortomonoiliac grafts. The Z-stent-based devices were implanted with the assistance of an occlusion balloon placed in the distal descending thoracic aorta. RESULTS All patients survived the procedure with successfully excluded AAAs. Two patients had relatively short hospital stays (4 and 14 days), while the third required prolonged treatment for pre-existing conditions. All patients required blood transfusions; 2 developed significant coagulopathies. Definitive management was delayed significantly by imaging protocols and graft construction. CONCLUSIONS Endovascular repair of ruptured aortic aneurysms is feasible. Proximal aortic control is readily attainable with the use of an aortic occlusion balloon placed through the left axillary artery. The absence of a laparotomy, extensive retroperitoneal dissection, and aortic cross-clamping likely contributes to patient survival; however, the delay in operative therapy to obtain adequate imaging and construct an endograft could be a hindrance to the ultimate success of this approach. The concepts of alternative aortic imaging techniques and endograft design, construction, and storage must be addressed.
