Enhancing predictive accuracy of the cardiac risk score in open abdominal aortic surgery: the role of left ventricular wall motion abnormalities. Front Cardiovasc Med 2023; 10:1239153. [PMID: 38107265 PMCID: PMC10722257 DOI: 10.3389/fcvm.2023.1239153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Accepted: 11/20/2023] [Indexed: 12/19/2023] Open
Abstract
Background Open abdominal aortic surgery carries many potential complications, with cardiac adverse events being the most significant concern. The Vascular Study Group Cardiac Risk Index (VSG-CRI) is a commonly used tool for predicting severe cardiac complications and guiding clinical decision-making. However, despite the potential prognostic significance of left ventricular wall motion abnormalities (LVWMAs) and reduced LV ejection fraction (LVEF) for adverse outcomes, the VSG-CRI model has not accounted for them. Hence, the main objective of this study was to analyze the added value of LV wall motion on the discriminatory power of the modified VSG-CRI in predicting major postoperative cardiac complications. Methods A prospective study was conducted involving 271 patients who underwent elective abdominal aortic surgery between 2019 and 2021. VSG-CRI scores were calculated, and preoperative transthoracic echocardiography was conducted for all patients. Subsequently, a modified version of the VSG-CRI, accounting for reduced LVEF and LVWMAs, was developed and incorporated into the dataset. The postoperative incidence of the composite endpoint of major adverse cardiac events (MACEs), including myocardial infarction, clinically relevant arrhythmias treated with medicaments or by cardioversion, or congestive heart failure, was assessed at discharge from the index hospitalization, with adjudicators blinded to events. The predictive accuracy of both the original and modified VSG-CRI was assessed using C-Statistics. Results In total, 61 patients (22.5%) experienced MACEs. Among these patients, a significantly higher proportion had preoperative LVWMAs compared to those without (62.3% vs. 32.9%, p < 0.001). Multivariable regression analysis revealed the VSG-CRI [odds ratio (OR) 1.46, 95% confidence interval (CI) 1.21-1.77; p < 0.001] and LVWMA (OR 2.76; 95% CI 1.46-5.23; p = 0.002) as independent predictors of MACEs. Additionally, the modified VSG-CRI model demonstrated superior predictability compared to the baseline VSG-CRI model, suggesting an improved predictive performance for anticipating MACEs following abdominal aortic surgery [area under the curve (AUC) 0.74; 95% CI 0.68-0.81 vs. AUC 0.70; 95% CI 0.63-0.77; respectively]. Conclusion The findings of this study suggest that incorporating preoperative echocardiography can enhance the predictive accuracy of the VSG-CRI for predicting MACEs after open abdominal aortic surgery. Before its implementation in clinical settings, external validation is necessary to confirm the generalizability of this newly developed predictive model across different populations.

Assessment of the impact of frailty on adverse surgical outcomes in patients undergoing surgery for intracranial tumors using modified frailty index: A systematic review and meta-analysis. J Clin Neurosci 2023; 114:120-128. [PMID: 37390775 DOI: 10.1016/j.jocn.2023.06.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 06/09/2023] [Accepted: 06/17/2023] [Indexed: 07/02/2023]
Abstract
BACKGROUND Modified frailty index (MFI) is an emerging quantitative measure of frailty; however, the quantified risk of adverse outcomes in surgeries for intracranial tumors associated with increasing MFI scores has not been thoroughly reviewed in a comprehensive manner. METHODS MEDLINE (PubMed), Scopus, Web of Science, and Embase were searched to identify observational studies on the association between 5 and 11 item-modified frailty index (MFI) and perioperative outcomes for neurosurgical procedures including complications, mortality, readmission, and reoperation rate. Primary analysis pooled all comparisons with MFI scores greater than or equal to 1 versus non-frail participants using mixed-effects multilevel model for each outcome. RESULTS In total, 24 studies were included in the review and 19 studies with 114,707 surgical operations were included in the meta-analysis. While increasing MFI scores were associated with worse prognosis for all included outcomes, reoperation rate was only significantly higher in patients with MFI ≥ 3. Among surgical pathologies, glioblastoma was influenced by a greater extent to the impact of frailty on complications and mortality that most other etiologies. In agreement with qualitative evaluation of the included studies, meta-regression did not reveal association between mean age of the comparisons and complications rate. CONCLUSION The results of this meta-analysis provides quantitative risk assessment of adverse outcomes in neuro-oncological surgeries with increased frailty. The majority of literature suggests that MFI is a superior and independent predictor of adverse outcomes compared to age.

Abstract
OBJECTIVE This modelling study aimed to estimate the comorbidity burden for four common non-communicable diseases with ischaemic heart diseases (IHD) in Iran during a period of 28 years. DESIGN Analysis of the burden of comorbidity with IHD based on data included prevalence rates and the disability weight (DW) average for calculating years lived with disability (YLDs) from the Iran population based on the Global Burden of Disease (GBD) study. SETTING Population-based available data in GBD 2017 study of Iran population. PARTICIPANT The source of data was the GBD 2017 Study. We evaluated IHD, major depressive disorder (MDD), diabetes mellitus (DM), ischaemic stroke (IS), and osteoarthritis (OA) age-standardised prevalence rates and their DW. MAIN OUTCOME MEASURES A new formula that modified the GBD calculator was used to measure the comorbidity YLDs. In the new formula, some multipliers were considered, measuring the departure from independence. RESULT The contribution of total comorbidity for each combination of IHD with DM, MDD, IS and OA was 2.5%, 2.0%, 1.6% and 2.9%, respectively. The highest YLD rates were observed for IHD_MDD, 16.5 in 1990 and 17.0 in 2017. This was followed by IHD_DM, from 11.5 to 16.9 per 100 000. The YLD rates for IHD_OA changed slightly (6.5-6.7) per 100 000, whereas there was a gradual reduction in the trends of IHD-IS, from 4.0-4.5 per 100 000. CONCLUSION Of the four comorbidities studied, the highest burden was due to the coexistence of MDD with IHD. Our results highlight the importance of addressing the burden of comorbidities when studying the burden of IHD or any other non-communicable disease.

Abstract
Introducción. En las últimas décadas, la terapia endovascular en aneurismas aórticos abdominales ha ganado un papel representativo en los escenarios quirúrgicos, lo que nos motivó a conocer los resultados de este procedimiento en nuestra población.
Métodos. Estudio analítico retrospectivo en el cual se incluyeron los primeros 50 casos de aneurismas aórticos abdominales con terapia endovascular, en la ciudad de Manizales, Colombia, entre los años 2015 y 2021. Se describió la población estudiada, la relación de los antecedentes prequirúrgicos con las complicaciones posoperatorias, la estancia hospitalaria y la mortalidad.
Resultados. La edad promedio fue de 73 años, el sexo predominante fue el femenino (72 %), el aneurisma fusiforme fue el tipo más frecuente (63,3 %), con un diámetro promedio de 70 mm (+/- 17,3 mm). En relación con los antecedentes, el más frecuente fue hipertensión arterial (86 %), encontrándose una asociación entre la presencia de enfermedad pulmonar obstructiva crónica e hipertensión arterial con las complicaciones. Se encontró también relación entre el valor de creatinina con las complicaciones. Las complicaciones tempranas fueron de carácter leve en la mayoría de los casos (30,6 %), a diferencia de las tardías, que fueron principalmente graves (12,5 %), asociadas a una mortalidad del 10,2 % y una estancia hospitalaria promedio de 10,8 días (mediana de 5 días).
Conclusiones. La población analizada tiene una alta carga de morbilidad, en la cual factores como los antecedentes médicos prequirúrgicos y la función renal, se asocian con una mayor morbilidad postquirúrgica y mortalidad.

Abstract
OBJECTIVE We sought to detail the process of establishing a surgical aortic telehealth program and report the outcomes of a 5-year experience. METHODS A telehealth program was established between two regional Veterans Affairs hospitals, one of which was without a comprehensive aortic surgical program, until such a program was established at the referring institution. A retrospective review was performed of all patients who underwent aortic surgery from 2014 to 2019. The operative data, demographics, perioperative complications, and follow-up data were reviewed. RESULTS From 2014 to 2019, 109 patients underwent aortic surgery for occlusive and aneurysmal disease. Preoperative evaluation and postoperative follow-up were done remotely via telehealth. The median age of the patients was 68 years, 107 were men (98.2%), 28 (25.7%) underwent open aortic repair, and 81 (74.3%) underwent endovascular repair. Of the 109 patients, 101 (92.7%) had a median follow-up of 24.3 months, 5 (4.6%) were lost to follow-up or were noncompliant, 2 (1.8%) were noncompliant with their follow-up imaging studies but responded to telephone interviews, and 1 (0.9%) moved to another state. At the 30-day follow-up, eight patients (7.3%) required readmission. Four complications were managed locally, and four patients (3.6%) required transfer back to the operative hospital for additional care. CONCLUSIONS Telehealth is a great tool to provide perioperative care and long-term follow-up for patients with aortic pathologies in remote locations. Most postoperative care and complications can be managed remotely, and patient compliance for long-term follow-up is high.

Abstract
Background: High-risk patients undergoing elective surgery are at risk for perioperative complications, including readmissions and death. Advance care planning (ACP) may allow for preparation for such events. Objectives: (1) To assess the completion rate of advance directives (ADs) and their association with one year readmissions and mortality (2) to examine clinical events for decedents. Design: This is an observational cohort study conducted through chart review. Setting/Subjects: Subjects were 400 patients undergoing preoperative evaluation for elective surgery at two hospitals in the United States. Measurements: The prevalence of ADs at the time of surgery and at one year, readmissions, and mortality at one year were determined. Results: Three-hundred ninety patients were included. In total, 102 (26.4%) patients were readmitted, yet did not complete an AD. Seventeen (4.4%) patients filed an AD during follow-up. Nineteen patients died and mortality rate was 4.9%. There was a significant association between completing an AD before death. Of the decedents, seven (37%) underwent resuscitation, but only four had ADs. Conclusions: Many high-risk surgical patients would benefit from ADs before clinical decline. Preoperative clinics present a missed opportunity to ensure ACP occurs before complications arise.

Abstract
Introduction Abdominal aortic aneurysms (AAA) are uncommon in young adults ≤55 years of age. There is a lack of literature on clinical characteristics, risk factors, and therapeutic outcomes so we present a case series of 11 patients of AAA aged ≤55 years. Methods We included single-center retrospective case series between 2013 to 2020. We reviewed 44 patients who were operated for AAA in a tertiary care center in India. We identified 13 patients who were ≤55 years; two patients with incomplete records were excluded. A patient information sheet was used to retrieve demographic data, clinical presentation, outcomes, and follow-up. Results Out of 11 patients, 10 were men. Nine patients (81.8%) had symptomatic AAA. The majority (45.4%) exhibited an infrarenal aneurysm and the median size of the aneurysm was 5.8 cm (IQR: 5.5-6.4 cm). Eight patients (72.7%) had a history of smoking. Hypertension was observed in six patients and one patient had associated coronary artery disease. Clamping time was > 45 minutes among three patients; all smokers. Blood loss was > 500 ml in five patients. The median length of hospital stay was 10 days (7-40); more among patients with metabolic equivalents (METS) score < 4, 14.5 (8-19) days. No grade III-IV complications and mortality were noted with a median follow-up of 15 months, with all patients living. Conclusion The aneurysm was symptomatic in the majority of participants. An association of smoking in increasing both the median clamping time and length of hospital stay was seen. No mortality and good disease-free follow-up suggested good outcomes.

BACKGROUND The purpose of this study is to evaluate risk factors for pneumonia following THA and TKA. METHODS Patients were identified from the American College of Surgeons National Quality Improvement Database (NSQIP) who experienced postoperative pneumonia after undergoing primary THA and TKA. RESULTS Many characteristics including old age, anemia, diabetes, cardiac comorbidities, dialysis, and smoking were independent risk factors for postoperative pneumonia after THA or TKA. CONCLUSION This analysis offers new evidence on risk factors associated with the development of pneumonia after THA and TKA. These risk factors can help guide clinicians in preventing postoperative pneumonia after THA and TKA.

Abstract
OBJECTIVE Age is an independent risk factor for mortality after both elective open surgical repair (OSR) and endovascular aneurysm repair (EVAR). As a result of an ageing population, and the less invasive nature of EVAR, the number of patients over 80 years (octogenarians) being treated is increasing. The mortality and morbidity following aneurysm surgery are increased for octogenarians. However, the mortality for octogenarians who have either low or high peri-operative risks remains unclear. The aim of this study was to provide peri-operative outcomes of octogenarians vs. non-octogenarians after OSR and EVAR for intact aneurysms, including separate subanalyses for elective and urgent intact repair, based on a nationwide cohort. Furthermore, the influence of comorbidities on peri-operative mortality was examined. METHODS All patients registered in the Dutch Surgical Aneurysm Audit (DSAA) undergoing intact AAA repair between 2013 and 2018, were included. Patient characteristics and peri-operative outcomes (peri-operative mortality, and major complications) of octogenarians vs. non-octogenarians for both OSR and EVAR were compared using descriptive statistics. Multivariable logistic regression analyses were used to examine whether age and the presence of cardiac, pulmonary, or renal comorbidities were associated with mortality. RESULTS This study included 12 054 EVAR patients (3 015 octogenarians), and 3 815 OSR patients (425 octogenarians). Octogenarians in both the EVAR and OSR treatment groups were more often female and had more comorbidities. In both treatment groups, octogenarians had significantly higher mortality rates following intact repair as well as higher major complication rates. Mortality rates of octogenarians were 1.9% after EVAR and 11.8% after OSR. Age ≥ 80 and presence of cardiac, pulmonary, and renal comorbidities were associated with mortality after EVAR and OSR. CONCLUSION Because of the high peri-operative mortality rates of octogenarians, awareness of the presence of comorbidities is essential in the decision making process before offering aneurysm repair to this cohort, especially when OSR is considered.

Abstract
The aim of this study was to review and analyze the neurosurgery body of literature to document the current knowledge of frailty within neurosurgery, standardizing terminology and how frailty is defined, including the different levels of frailty, while determining what conclusions can be drawn about frailty's impact on neurosurgical outcomes. While multiple studies on frailty in neurosurgery exist, no literature reviews have been conducted. Therefore, we performed a literature review in order to organize, tabulate, and present findings from the data to broaden the understanding about what we know from frailty and neurosurgery. We performed a PubMed search to identify studies that evaluated frailty and neurosurgery. The terms "frail," "frailty," "neurosurgery," "spine surgery," "craniotomy," and "neurological surgery" were all used in the query. We then organized, analyzed, and summarized the comprehensive frailty and neurosurgical literature. The literature contained 25 published studies analyzing frailty in neurosurgery between December 2015 and December 2018. Five of these studies were cranial neurosurgical studies, the remaining studies focused on spinal neurosurgery. Over 100,000 surgical cases were analyzed among the 25 studies. Of these, 18 studies demonstrated that increasing frailty was associated with increased rate of complications, 10 studies showed that frailty was associated with higher mortality rates, 11 studies demonstrated an association between frailty and increased hospital length of stay, and 5 studies noted that higher frailty was associated with discharge to a higher level of care. The current body of literature repeatedly demonstrates that frailty is associated with worse outcomes across the neurosurgical subspecialties.

Abstract
BACKGROUND Currently used pre-operative prediction scores for postoperative pulmonary complications (PPCs) use patient data and expected surgery characteristics exclusively. However, intra-operative events are also associated with the development of PPCs. OBJECTIVE We aimed to develop a new prediction score for PPCs that uses both pre-operative and intra-operative data. DESIGN This is a secondary analysis of the LAS VEGAS study, a large international, multicentre, prospective study. SETTINGS A total of 146 hospitals across 29 countries. PATIENTS Adult patients requiring intra-operative ventilation during general anaesthesia for surgery. INTERVENTIONS The cohort was randomly divided into a development subsample to construct a predictive model, and a subsample for validation. MAIN OUTCOME MEASURES Prediction performance of developed models for PPCs. RESULTS Of the 6063 patients analysed, 10.9% developed at least one PPC. Regression modelling identified 13 independent risk factors for PPCs: six patient characteristics [higher age, higher American Society of Anesthesiology (ASA) physical score, pre-operative anaemia, pre-operative lower SpO2 and a history of active cancer or obstructive sleep apnoea], two procedure-related features (urgent or emergency surgery and surgery lasting ≥ 1 h), and five intra-operative events [use of an airway other than a supraglottic device, the use of intravenous anaesthetic agents along with volatile agents (balanced anaesthesia), intra-operative desaturation, higher levels of positive end-expiratory pressures > 3 cmH2O and use of vasopressors]. The area under the receiver operating characteristic curve of the LAS VEGAS risk score for prediction of PPCs was 0.78 [95% confidence interval (95% CI), 0.76 to 0.80] for the development subsample and 0.72 (95% CI, 0.69 to 0.76) for the validation subsample. CONCLUSION The LAS VEGAS risk score including 13 peri-operative characteristics has a moderate discriminative ability for prediction of PPCs. External validation is needed before use in clinical practice. TRIAL REGISTRATION The study was registered at Clinicaltrials.gov, number NCT01601223.

Abstract
BACKGROUND Postoperative complication following ventral hernia repair (VHR) is a major clinical and financial burden. Preoperative risk assessment is necessary to minimize adverse outcomes following VHR. This study examines the ability of an independent parameter to predict postoperative morbidity following VHR. METHODS A retrospective analysis of 58 patients who underwent VHR by component separation between January 2009 and December 2013 was performed. Preoperative abdominal CT scans were analyzed to assess sarcopenia. Sarcopenia was determined using the Hounsfield unit average calculation (HUAC), a measure of psoas muscle size and density. Sarcopenia was defined as an HUAC score of less than 19.6 HU calculated using receiver operating characteristic (ROC) analysis and the Youden index. Multivariate analysis was performed to analyze the association of sarcopenia and postoperative complications. RESULTS Preoperative sarcopenia was associated with an increased risk for postoperative complications (odds ratio [OR] = 5.3; p = 0.04). Preexisting gastrointestinal conditions such as ulcerative colitis or colon cancer were associated with an increased risk for postoperative complications (OR = 5.7; p = 0.05). A significantly higher rate of hernia recurrence (33.3% vs. 10.8% [p = 0.04]) and renal failure (19% vs. 2.7% [p = 0.03]) was noted in patients with sarcopenia when compared to patients without sarcopenia. CONCLUSIONS Sarcopenia is an independent risk factor for postoperative complications in patients who underwent VHR. Assessment of sarcopenia using the HUAC score provides an opportunity for the adjustment of perioperative care plans to minimize postoperative complication rates.

Abstract
Background Recent studies reviewing large patient databases suggested that age may be an independent risk factor for abdominoplasty. However, these investigations by design considered only short-term major complications. Objectives The purpose of this investigation was: (1) to compare the safety of abdominoplasty in an elderly and younger patient population; (2) to determine the complication rates across all spectrums: major, minor, local, and systemic; and (3) to evaluate complications occurring both short and long term. Methods Abdominoplasty procedures performed from 2010 to 2015 were retrospectively reviewed. Subjects were divided into two groups: ≤59 years old and ≥60 years old. Major, minor, local, and systemic complications were analyzed. Patient demographics, comorbidities, perioperative details, adjunctive procedures were also assessed. Results A total of 129 patients were included in the study: 43 in the older and 86 in the younger age group. The median age of The elderly and young groups was 65.0 and 41.5 years, respectively (P < .001). No statistically significant differences in major, minor, local, or systemic complications were found when both age groups were compared. Major local, major systemic, minor local, and minor systemic in the elderly were 6.9%, 2.3%, 18.6%, and 2.3%, while in the younger patients were 9.3%, 4.7%, 10.5%, and 0.0%, respectively (P > .05). Median follow-up time of the elderly (4.0 months) was no different than the younger (5.0 months) patients (P > .07). Median procedure time in the elderly (4.5 hours) was no different than the younger group (5.0 hours) (P = .4). The elderly exhibited a greater American Society of Anesthesiologist score, median body mass index (28.7 vs 25.1 kg/m2), and number of comorbidities (2.7 vs 0.9) (P < .001). Conclusions There was no significant difference in either major or minor complications between the two groups. This suggests that with proper patient selection, abdominoplasty can be safely performed in the older age patient population. Level of Evidence 2.

Abstract
INTRODUCTION In the absence of endovascular aneurysm repair due to financial constraints, Abdominal Aortic Aneurysm (AAA) in Sri Lanka is managed exclusively by open surgery. We report our experience with open AAA repair with emphasis on peri-operative morbidity and mortality. METHODS Seventy nine consecutive open AAA repairs were carried out between April 2004 and March 2010. A multiple regression model was used to identify predictors of significant peri-operative morbidity and mortality. RESULTS Mean age of the study cohort was 68 years. There were 63 (80%) males and 16 (20%) females. Mean aneurysm diameter was 6.4 (3.5-9.70) cm. Twenty seven (34%) underwent emergency surgical repair (group-1) while 52 (66%) had elective repair (group-2). The peri-operative mortality was 10/27 (37%) in group-1, 4/52 (7.6%) in group-2, (p = 0.0035). Significant post-operative morbidity was seen in 5/17 (29%) in group-1 and 7/48 (15%) in group-2, (p = 0.27). Aneurysm diameter >7 cm (p = 0.001), emergency repair (p = 0.004), history of smoking (p = 0.002), aortic cross-clamp time >60 minutes (p = 0.044), and need for post-operative ventilwation >24 hours (p = 0.024) were found to be independent predictors of peri-operative mortality or significant morbidity. CONCLUSION Open aneurysm repair still has a strong place especially in the limited resource setting, with acceptable outcomes.

Abstract
As the population continues to age, we will continue to encounter issues involving aging and the elderly. Despite these issues, knowledge is expanding and evolving with new solutions to ongoing problems. Mechanistically, frailty at its root is a symptom of growing old, with cascades and circuitous feedback between organ systems at all levels. Clinically, frailty is as equally dynamic and its multifactorial nature represents a unique challenge to the surgical community and warrants the integration of geriatric assessment into clinical practice. Integration within clinical practice includes using an interdisciplinary approach, where surgeons work with anesthesiologists, geriatricians, nursing, rehabilitation, nutritionists, and other support staff to provide holistic assessment, efficient delivery, and higher quality of care. This in hand, recognition of frailty can occur in a timely fashion to initiate treatment, decreasing the risk of morbidity and mortality for improved surgical outcomes.

Abstract
BACKGROUND Recovery is an integral part of the surgical process and measuring it provides insight into the impact of surgical innovation. This study used a recently validated instrument, the Convalescence and Recovery Evaluation (CARE), to measure return to baseline health after surgery and explore clinical factors associated with recovery. STUDY DESIGN Patient health was measured among 96 patients before and after abdominal and pelvic surgery. Patients were grouped by time to recovery of 90% of baseline status. chi2 Tests and logistic models were used to measure relationships between recovery time and patient characteristics, processes of care, and outcomes. RESULTS Return to baseline health was reached by 44% of patients within 2 weeks, 28% between 2 and 4 weeks, and 28% after 4 weeks. Patients who recovered faster were younger, female, single, and undergoing ambulatory surgery for benign diseases. Patients who were married, underwent surgery for cancer, or had bowel surgery were more likely to require longer recovery time. CONCLUSIONS Several patient and clinical characteristics were found to be associated with recovery after surgery. CARE appears to be sensitive to these factors and may be useful for informed decision making, assessing changes in processes of care, and evaluating the impact of surgical innovations on recovery.

Abstract
Diabetes mellitus (DM) is an independent predictor for morbidity and mortality in the general population, which is even more apparent in patients with concomitant cardiovascular risk factors. As the prevalence of DM is increasing, with an ageing general population, it is expected that the number of diabetic patients requiring surgical interventions will increase. Perioperative hyperglycaemia, without known DM, has been identified as a predictor for morbidity and mortality in patients undergoing surgery. Moreover, early studies showed that intensive blood-glucose-lowering therapy reduced both morbidity and mortality among patients admitted to the postoperative intensive care unit (ICU). However, later studies have doubted the benefit of intensive glucose control in medical-surgical ICU patients. This article aims to comprehensively review the evidence on the use of perioperative intensive glucose control, and to provide recommendations for current clinical practice. A systematic review was performed of the literature on perioperative intensive glucose control. Based on this literature review, we observed that intensive glucose control in the perioperative period has no clear benefit on short-term mortality. Intensive glucose control may even have a net harmful effect in selected patients. In addition, concerns on the external validity of some studies are important barriers for widespread recommendation of intensive glucose control in the perioperative setting. We propose that guidelines recommending intensive glucose control should be re-evaluated. In addition, moderate tight glucose control should currently be regarded as the safest and most efficient approach to patients undergoing major vascular surgery.

Abstract
Although major vascular surgery is performed with increasing frequency in elderly people, the impact of age on outcomes is uncertain. We evaluated the perioperative (30-day) outcomes for patients who underwent major elective vascular operations under general or peripheral anesthesia in their eighties and nineties in a 14-year period. Data for all consecutive 3,060 patients (456 of them > or years old) who underwent 3,314 elective vascular surgery procedures were prospectively entered into a computerized vascular registry. Detailed information was collected on patients' preoperative status, type of procedure and anesthesia, perioperative outcomes, and predictors of perioperative outcomes. The end points of the study were perioperative death and main surgical complications. Perioperative all-cause mortality rates varied across operations and were higher in elderly than in younger patients (1.4% vs. 0.2%, P = 0.014) after abdominal surgery (2.4% vs. 0.1%, P = 0.006) and especially after abdominal aortic aneurysm repair (2.8% vs. 0%, P = 0.035). In the elderly cohort, the mortality rate was <1% for almost 60% of all operations. In logistic regression analysis, only preoperative hypertension (odds ratio [OR] = 72.5, 95% confidence interval [CI] 9.4-557.6), congestive heart failure (OR = 16.5, 95% CI 2.3-115.9), and perioperative cardiac (OR = 20.7, 95% CI 1.6-273.8) and pulmonary (OR = 41.7, 95% CI 7.9-218.9) complications were associated with a higher 30-day death risk. In this series, perioperative outcomes were not influenced by the type of elective surgical procedure. Though overall mortality after major vascular surgery was higher in patients > or 80 years old, age per se was not an independent factor of a higher perioperative mortality risk or fatal and nonfatal complications.

Abstract
OBJECTIVE To investigate risk factors that influence survival after open abdominal aortic aneurysm (AAA) repair in all elective patients treated by a single surgeon at a tertiary referral center. METHODS The series includes 855 asymptomatic infrarenal AAAs in 732 men (86%) and 123 women with median ages of 69 and 71 years, respectively. Noninvasive myocardial imaging (n = 325), coronary arteriography (n = 418), or both were performed before surgery in 687 patients (80%), and 100 patients (15%) underwent preliminary coronary artery bypass grafting (n = 78) or percutaneous transluminal coronary angioplasty (n = 22) before their AAA procedures. Survival was assessed by using logistic regression analysis, proportional hazards models, and Kaplan-Meier estimations. RESULTS The operative mortality rate was 2.5%, ranging only from 1.8% to 2.8% since 1980. Late survival rates (70% at 5 years, 36% at 10 years, and 16% at 15 years) also remained remarkably similar during five arbitrary intervals comprising the entire study period. On multivariable analysis, overall mortality rates were adversely affected by older age (P < .001), increased creatinine levels (P < .001), straight aortic replacement grafting (P < .001), larger aneurysm diameter (P = .036), and chronic obstructive pulmonary disease (P = .012). The risk for any early or late death was favorably influenced by preliminary coronary artery bypass grafting or percutaneous transluminal coronary angioplasty (hazard ratio, 0.76; 95% confidence interval, 0.59-0.98; P = .035) even when a separate multivariable model was fit to accommodate nine other patients who also had preliminary coronary intervention but developed symptomatic AAAs before elective repair could be performed (hazard ratio, 0.78; 95% confidence interval, 0.61-0.99; P = .044). CONCLUSIONS Patient age and medical risk factors determine survival after open AAA repair to a very similar degree irrespective of the era when the operation is performed. In this particular series, preliminary coronary intervention seemed to benefit patients with severe coronary artery disease.

Abstract
UNLABELLED The objective of our study was to assess the effect of comorbidities (hypertension, diabetes, obesity, and their combinations) on postoperative complications and discharge status in patients having shoulder, hip, and knee arthroplasty (n = 959,839). The association between outcomes and each of the comorbidities was assessed using multivariable logistic regression after adjusting for age, race, household income, gender, and hospital volume. In the multivariable models, postoperative complications were more likely in patients with hypertension, diabetes, or obesity as compared with patients without these comorbidities (for hypertension, odds ratio = 1.07; 95% confidence interval range, 1.04-1.11; for obesity, odds ratio = 1.3; 95% confidence interval range, 1.22-1.41). The likelihood of a nonhomebound disposition of patients on discharge was 1.30 times (95% confidence interval range, 1.27-1.32) in patients with diabetes and 1.45 times (95% confidence interval range, 1.40-1.49) in patients who were obese as compared with patients without these respective comorbidities. Patients with a combination of comorbidities also had a higher likelihood of postoperative complications and nonhomebound discharge. Results of our study showed that hypertension, diabetes, and obesity are independent predictors of increased postoperative complications and non-homebound discharge in patients undergoing shoulder, hip, or knee arthroplasty. LEVEL OF EVIDENCE Prognostic study, Level II-1 (retrospective study). See the Guidelines for Authors for a complete description of levels of evidence.

Abstract
OBJECTIVES To gather information about surgical outcomes for patients in their 80s and 90s. DESIGN Prospective cohort study. SETTING Veterans Affairs Medical Centers. PARTICIPANTS Patients (26,648 aged >/=80; 568,263 aged <80) enrolled in the Veterans Affairs National Surgical Quality Improvement Project (NSQIP) who had noncardiac surgery between 1991 and 1999. METHODS Data were collected prospectively from medical records and healthcare providers. Detailed information was collected about patients' preoperative status, intraoperative experience, and postoperative outcomes. Postoperative outcomes were survival status at 30 days (deaths from any cause occurring during hospitalization and after hospital discharge were captured) and the occurrence of 21 selected surgical complications within 30 days postoperatively: wound complications (3 types), respiratory complications (4), urinary tract complications (3), nervous system complications (3), cardiac complications (3), and other complications (5). MEASUREMENTS Mortality and the occurrence of 21 surgical complications within 30 days of surgery. RESULTS Thirty-day all-cause mortality rates varied widely across operations and were higher for patients aged 80 and older than for younger patients (8% vs 3%, P<.001). Mortality rates for those aged 80 and older were less than 2% for many commonly performed operations (e.g., transurethral prostatectomy, hernia repair, knee replacement, carotid endarterectomy). Of patients aged 80 and older, 20% had one or more postoperative complications, and patients who suffered complications had higher 30-day mortality than those who did not (26% vs 4%, P<.001). For 11 of the 21 complications, mortality for patients aged 80 and older was greater than 33%. The risk factors for poor outcomes were the same for older and younger patients, and the NSQIP Mortality Risk model performed well on patients aged 80 and older (C statistic=0.83). CONCLUSION A substantial minority of patients aged 80 and older died or suffered a complication within 30 days of surgery, but for many operations mortality rates were extremely low. Postoperative complications were associated with high 30-day mortality in patients aged 80 and older.

Abstract
Patients who have vascular disease who are to undergo an operation are at risk for developing perioperative and postoperative complications caused by coexisting diseases. A comprehensive preoperative evaluation is critical in identifying these coexisting diseases, and the anesthetic plan might require modification. This article focuses on important aspects of the pulmonary, endocrine (diabetes), and renal systems during the preoperative evaluation of the vascular surgical patient.

Abstract
INTRODUCTION Advanced age is generally acknowledged as a risk factor for adverse surgical outcomes, but little information exists to define the magnitude of this association from a population-based perspective. This study was undertaken to determine the relation of patient age to complications following abdominal aortic aneurysm (AAA) repair in a population-based experience. METHODS This study was based upon data from 6397 patients with a primary diagnosis of intact AAA and a procedure code for repair of AAA from the Nationwide Inpatient Sample (NIS) in 2000. The NIS is a 20% stratified random sample representative of all United States hospitals. Primary outcome variables were postoperative complications determined from secondary diagnostic codes. Adjustment for confounding variables was performed using multiple logistic regression. RESULTS At least one complication affected 29% of patients. Increasing age correlated with a higher risk of having one or more complications (51-60 years, 18.8%; 61-70 years, 27.3%; 71-80 years, 31.2%; >80 years, 34.3%; P < 0.01). Comparison of the oldest to the youngest age group revealed an increased incidence of pulmonary insufficiency (13.9% versus 6.4%), pneumonia (7.7% versus 3.0%), reintubation (9.5% versus 3.9%), acute renal failure (8.8% versus 2.5%), myocardial infarction (4.3% versus 1.6%), and mortality (7.9% versus 1.1%). The association of increasing age to complications and mortality persisted after adjusting for patient case-mix. CONCLUSIONS Older patient age is independently associated with an increased risk of major postoperative complications after AAA repair. The increasing age of the United States population will compound this healthcare problem. Quality improvement efforts must focus on minimizing complication rates in elderly patients undergoing common vascular surgical procedures including AAA repair.

Abstract
Patients undergoing endovascular abdominal aortic aneurysm (AAA) repair have lower perioperative morbidity and leave the hospital earlier than patients undergoing open repair. However, potential complications require continuous surveillance of endografts and there are few data regarding their long-term fate. If an open operation were well tolerated, this might be a preferable alternative. The purpose of this study was to identify patients with lower morbidity and shorter hospital stay following open AAA repair and to analyze factors that might point to open repair as the preferred approach. We performed a retrospective review of all patients who underwent AAA repair between 1995 and 2000 at our institution. All patients with ruptured aneurysms and those that required renal, celiac, or superior mesenteric reconstructions during the AAA repair were excluded. Patient demographics, preoperative comorbid conditions, intraoperative data, and postoperative complications were analyzed in detail. A total of 115 patients fulfilled the inclusion criteria. There was only one perioperative death (0.9%). The mean hospital stay was 8.1 days. A history of chronic obstructive pulmonary disease (COPD) and longer operative time were independent factors associated with prolonged hospital stay. Forty-one patients (35.6%) left the hospital in 5 or less days. Compared to the group with hospital stay >5 days, these patients had a lower incidence of COPD (7.3% vs. 25.7%, p < 0.05) and smaller-size AAAs (5.6 vs. 6.4 cm, p < 0.0001), and were more often operated on via a retroperitoneal approach (61% vs. 40.5%, p < 0.05). Their time in the operating room was less (3.5 vs. 4.5 hr, p < 0.0001), and they had less estimated blood loss (750 vs. 1500 cc, p < 0.001) and fewer transfusions (0.95 vs. 2.45 units, p < 0.0001). Patients without COPD and smaller AAAs that can be repaired via a retroperitoneal approach have a lower incidence of perioperative complications and a shorter hospital stay following open AAA repair. Until long-term results for endografts are available, our data suggest that these patients are well served with an open repair.

Abstract
BACKGROUND Elective juxtarenal abdominal aneurysm repair has a significantly lower mortality rate than suprarenal repair. Identification of factors affecting outcome may lead to a reduction in mortality rate for suprarenal repair. METHODS Data were collected prospectively between 1993 and 2000 for 130 patients who underwent type IV thoracoabdominal aneurysm (TAA) repair and 44 patients who had juxtarenal aneurysm (JRA) repair. Preoperative risk factors and operative details were compared between groups and related to outcome after TAA repair (there were only two deaths in the JRA group). RESULTS The in-hospital mortality rate was significantly higher following TAA repair (20.0 per cent; 26 of 130 patients) than JRA repair (4.5 per cent; two of 44). Raised serum creatinine concentration was the only preoperative factor (P = 0.013) and visceral ischaemia the only significant operative factor (P = 0.001) that affected mortality after TAA repair. CONCLUSION JRA repair was performed with similar risks to those of infrarenal aneurysm repair. Impaired preoperative renal function was related to death following TAA repair and conservative treatment should be considered for patients with a serum creatinine level above 180 micromol/l. Reducing the duration of visceral ischaemia might improve outcome.

Abstract
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
OBJECTIVE Patients undergoing abdominal aortic aneurysm repair have a high incidence of coexisting cardiac disease. The traditional cardiac risk stratification for open abdominal aortic aneurysm surgery may not apply to patients undergoing endoluminal graft exclusion. The purpose of this study was to examine predictive risk factors for perioperative cardiac events. METHODS As part of multiple prospective endograft trials approved by the US Food and Drug Administration, data for 365 patients who underwent endoluminal graft repair from 1996 to 2001 were collected. Variables included for analysis were age and sex; history of smoking; presence of hypertension, diabetes mellitus, or renal insufficiency; Eagle clinical cardiac risk factors; American Society of Anesthesiologists index; type of anesthesia administered; estimated blood loss; preoperative hemoglobin level; preoperative use of beta-blocker therapy; duration of surgery; need for iliac artery conduit; and concomitant other vascular procedures. Univariate and multivariate logistic regression analysis were used to determine which variables were predictive of an adverse perioperative cardiac event, eg, Q wave and non-Q wave myocardial infarction (MI), congestive heart failure (CHF), severe arrhythmia, and unstable angina. RESULTS The study cohort included 322 men and 43 women (mean age, 74.2 years). Fifty-two (14.2%) postoperative cardiac events occurred: severe dysrhythmia in 15 patients (4.1%), MI in 14 patients (3.8%), non-Q wave MI in 8 patients (2.2%), CHF in 8 patients (2.2%), and unstable angina in 7 patients (1.9%). Univariate analysis demonstrated that age 70 years or older (P =.034), history of MI (P =.018), angina (P =.004), history of CHF (P <.001), two or more Eagle risk factors (P <.001), and lack of use of preoperative beta-blocker therapy (P =.005) were predictors of perioperative cardiac events. Multivariate analysis identified only age 70 years or older (P =.026), history of MI (P =.024) or CHF (P =.001), and lack of use of preoperative beta-blocker therapy (P =.007) as independent risk factors for an adverse cardiac event. CONCLUSIONS Age 70 years or older, history of MI or CHF, and lack of use of preoperative beta-blocker therapy are independent risk factors for perioperative cardiac events in patients undergoing endoluminal graft repair.

Abstract
Decision-making in regard to elective repair of abdominal aortic aneurysms (AAA) requires careful assessment of factors that influence rupture risk, operative mortality, and life expectancy. Individualized consideration of these factors in each patient is essential, and the role of patient preference is of increasing importance. It is not possible or appropriate to recommend a single threshold diameter for intervention which can be generalized to all patients. Based upon the best available current evidence, 5.5 cm is the best threshold for repair in an "average" patient. However, subsets of younger, good-risk patients or aneurysms at higher rupture risk may be identified in whom repair at smaller sizes is justified. Conversely, delay in repair until larger diameter may be best for older, higher-risk patients, especially if endovascular repair is not possible. Intervention at diameter <5.5 cm appears indicated in women with AAA. If a patient has suitable anatomy, endovascular repair may be considered, and it is most advantageous for older, higher-risk patients or patients with a hostile abdomen or other technical factors that may complicate standard open repair. With endovascular repair, perioperative morbidity and recovery time are clearly reduced; however, there is a higher reintervention rate, increased surveillance burden, and a small but ongoing risk of AAA rupture. There is no justification at present for different indications for endovascular repair, such as earlier treatment of smaller AAA. Until long-term outcome of endoluminal repair is better defined and results of randomized trials available, the choice between endovascular and open repair will continue to rely heavily on patient preference.

Abstract
As the population survives longer, surgery has become a much more common consideration. Preoperative management of these patients requires a working knowledge of changes associated with aging and the physiology of surgery and anesthesia. Using this information, patients can be clinically evaluated effectively and plans made for their perioperative care to minimize complications.

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
PURPOSE The purpose of this study was to determine the safety and durability of traditional surgical treatment for asymptomatic infrarenal abdominal aortic aneurysms (AAAs) in a large series of patients who underwent open operations during the decade preceding the commercial availability of stent graft devices for endovascular AAA repair. METHODS From 1989 to 1998, 1135 consecutive patients (985 men [87%], 150 women; mean age, 70 +/- 7 years) underwent elective graft replacement of infrarenal AAA. Computerized perioperative data have been supplemented with a retrospective review of hospital charts/outpatient records and a telephone canvass to calculate survival rates and the incidence rate of subsequent graft-related complications. Seventy-four patients (6.5%) were lost during a median follow-up period of 57 months for the entire series. RESULTS The 30-day mortality rate was 1.2%. The hospital course was completely uneventful for 939 patients (83%), and the median length of stay for all patients was 8 days. A total of 196 patients had single (n = 150; 13%) or multiple (n = 46; 4%) postoperative complications, which were more likely to occur in men (odds ratio [OR], 2.3; 95% confidence interval [CI], 1.1 to 5.2) and in patients with a history of congestive heart failure (OR, 3.7; 95% CI, 1.7 to 7.8), chronic pulmonary disease (OR, 1.9; 95% CI, 1.2 to 2.9), or renal insufficiency (OR, 2.5; 95% CI, 1.3 to 4.7). Kaplan-Meier method survival rate estimates were 75% at 5 years and 49% at 10 years. As was the case with early complications, the long-term mortality rate primarily was influenced by age of more than 75 years (risk ratio [RR], 2.2; 95% CI, 1.7 to 2.8) or previous history of congestive heart failure (RR, 2.1; 95% CI, 1.3 to 3.4), chronic pulmonary disease (RR, 1.5; 95% CI, 1.2 to 2.0), or renal insufficiency (RR, 3.2; 95% CI, 2.2 to 4.6). Of the 1047 patients who survived their operations and remained available for follow-up study, only four (0.4%) have had late complications that were related to their aortic replacement grafts. CONCLUSION These results reconfirm the exemplary success of open infrarenal AAA repair. The future of endovascular AAA repair is exceedingly bright, but until the long-term outcome of the current generation of stent grafts is adequately documented, their use should be justified by the presence of serious surgical risk factors.

Abstract
OBJECTIVE The impact of co-morbid conditions on early and late clinical outcomes after endovascular treatment of abdominal aortic aneurysm (AAA) was assessed in concurrent cohorts of patients stratified with respect to risk for intervention. SUMMARY BACKGROUND DATA As a minimally invasive strategy for the treatment of AAA, endovascular repair has been embraced with enthusiasm for all prospective patients who are suitable anatomical candidates because of the promise of achieving a durable result with a reduced risk of perioperative morbidity and mortality. METHODS From April 1994 to March 2001, endovascular AAA repair was performed in 236 patients using commercially available systems. A subset of patients considered at increased risk for intervention (n = 123) were categorized, as such, based on a preexisting history of ischemic coronary artery disease, with documentation of myocardial infarction (60%) or congestive heart failure (35%), or due to the presence of chronic obstructive disease (21%), liver disease, or malignancy. RESULTS Perioperative mortality (30-day) was 6.5% in the increased-risk patients as compared to 1.8% among those classified as low risk (P = NS). There was no difference between groups in age (74 +/- 9 years vs. 72 +/- 6 years; mean +/- SD), surgical time (235 +/- 95 minutes vs. 219 +/- 84 minutes), blood loss (457 +/- 432 mL vs. 351 +/- 273 mL), postoperative hospital stay (4.8 +/- 3.4 days vs. 4.0 +/- 3.9 days), or days in the ICU (1.3 +/- 1.8 days vs. 0.5 +/- 1.6 days). Patients at increased risk of intervention had larger aneurysms than low-risk patients (59 +/- 13 mm vs. 51 +/- 14 mm; P <.05). Stent grafts were successfully implanted in 116 (95%) increased-risk versus 107 (95%) low-risk patients (P = NS). Conversion rates to open operative repair were similar in increased-risk and low-risk groups at 3% and 5%, respectively. The initial endoleak rate was 22% versus 20%, based on the first CT performed (either at discharge or 1 month; P = NS). To date, increased-risk patients have been followed for 17.4 +/- 15 months and low-risk patients for 16.3 +/- 14 months. Kaplan-Meier analysis for cumulative patient survival demonstrated a reduced probability of survival among those patients initially classified as at increased risk for intervention (P <.05, Mantel-Cox test). Both cohorts had similar two-year primary and secondary clinical success rates of approximately 75% and 80%, respectively. CONCLUSIONS Early and late clinical outcomes are comparable after endovascular repair of AAA, regardless of risk-stratification. Notably, 2 years after endovascular repair, at least one in five patients was classified as a clinical failure. Given the need for close life-long surveillance and the continued uncertainty associated with clinical outcome, caution is dictated in advocating endovascular treatment for the patient who is otherwise considered an ideal candidate for standard open surgical repair.

Abstract
BACKGROUND The importance of diabetes mellitus (DM) as an independent risk factor for perioperative cardiac morbidity after vascular surgery is controversial. This study examined the impact of DM on perioperative outcomes and length of stay in patients who underwent major vascular surgery. METHODS Patients who underwent elective aortic reconstruction (n = 2792), lower extremity bypass (n = 3838), carotid endarterectomy (n = 5522), and major amputation (n = 3883) from 1997 to 1999 were identified in the National Surgical Quality Improvement Program database of the Department of Veterans Affairs. Outcomes assessed were death, cardiovascular complications (myocardial infarction, stroke, need for cardiopulmonary resuscitation), and length of stay. Multivariable logistic and linear regression models were used to control for patient demographics, procedure type, comorbidities, and diabetic complications. RESULTS Before adjustment for potential confounders, patients with diabetes had a higher incidence rate of perioperative death (3.9% versus 2.6%; P =.001) and cardiovascular complications (3.3% versus 2.6%; P =.01) when compared with patients without diabetes. After controlling for comorbid conditions, procedure type, and diabetic complications, only patients with DM who underwent treatment with insulin were at statistically increased risk for cardiovascular complications (odds ratio [OR], 1.48; 95% CI, 1.15 to 1.91). Neither DM treated with insulin (OR, 1.10; 95% CI, 0.85 to 1.41) nor DM treated with oral medications (OR, 0.96; 95% CI, 0.73-1.28) was an independent risk factor for death. Important independent risk factors for death included several conditions that are commonly associated with diabetes, including proteinuria, elevated creatinine level, history of congestive heart failure, and history of cerebrovascular accident. DM was also found to increase length of stay by as much as 38% even after adjustment for comorbidities. CONCLUSION Patients with diabetes have a higher incidence rate of death and cardiovascular complications. However, after controlling for specific comorbid conditions, the only independent association was between patients with insulin treatment and the risk of cardiovascular complications. DM does not appear to be an independent risk factor for postoperative mortality. All patients with diabetes, regardless of insulin use, have a prolonged length of stay after major vascular surgery.

Abstract
Between January 1, 1985 and December 31, 1998, we performed combined infrarenal aorta and carotid artery reconstruction in 152 consecutive patients. The mean age of these patients was 65.4 +/- 8.6 years (range, 43-88 years). Infrarenal aortic disease involved abdominal aortic aneurysm in 78 patients (44.7%) and occlusive aortoiliac lesions in 84 (55.3%). Carotid artery disease was detected by performing routine Doppler ultrasonography prior to aortic reconstruction. A total of 121 carotid lesions were asymptomatic (79.6%). A total of 32 patients (21%) had a history of contralateral carotid repair. Eighty-one patients (53.2%) presented with coronary artery disease diagnosed on the basis of clinical and/or laboratory testing. Concurrent lesions were diagnosed in the renal arteries of 43 patients (28.3%) and in the visceral arteries of 16 (10.5%). Based on the results of cardiac evaluation, eight patients underwent coronary revascularization before combined reconstruction. Renal or visceral artery reconstruction was carried out during the same procedure in 30 (19.7%) and 10 (6.6%) patients, respectively. Univariate analysis demonstrated six factors that were significantly associated with perioperative mortality and morbidity: age, coronary artery disease, chronic obstructive pulmonary disease, procedure time, intraoperative blood loss, and creatinemia over 140 micromol/L. Multivariate analysis showed that only the first four of these factors were independent. Actuarial survival in the overall population, including the patients who died during the perioperative period, was 73.9 +/- 7.1% at 5 years and 50.9 +/- 10% at 10 years. From our experience, we conclude that combined infrarenal aorta and carotid artery reconstruction can be performed with no additional operative risks and consequently is the strategy of choice. In our series neither procedure had any effect on the early or late outcome of the other. Our experience suggests that combined surgery is a safe alternative to staged surgery in patients with concurrent lesions involving the infrarenal aorta and carotid artery bifurcation.
