Do Complications After Pancreatoduodenectomy Have an Impact on Long-Term Quality of Life and Functional Outcomes? ANNALS OF SURGERY OPEN 2024; 5:e400. [PMID: 38911654 PMCID: PMC11191981 DOI: 10.1097/as9.0000000000000400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Accepted: 02/15/2024] [Indexed: 06/25/2024] Open
Abstract
Objective Our aim was to assess whether complications after pancreatoduodenectomy (PD) impact long-term quality of life (QoL) and functional outcomes. Background There is an increasing number of long-term post-PD survivors, but few studies have evaluated long-term QoL outcomes. Methods The EORTC QLQ-C30 and QLQ-PAN26 questionnaires were administered to patients who survived >5 years post-PD. Clinical relevance (CR) was scored as small (5-10), moderate (10-20), or large (>20). Patients were stratified based on whether they experienced a complication during the index hospitalization. Results Of 305 patients >5 years post-PD survivors, with valid contact information, 248 completed the questionnaires, and 231 had complication data available. Twenty-nine percent of patients experienced a complication, of which 17 (7.4%) were grade 1, 27 (11.7%) were grade 2, and 25 (10.8%) were grade 3. Global health status and functional domain scores were similar between both groups. Patients experiencing complications reported lower fatigue (21.4 vs 28.1, P < 0.05, CR small) and diarrhea (15.9 vs 23.1, P < 0.05, CR small) symptom scores when compared to patients without complications. Patients experiencing complications also reported lower pancreatic pain (38.2 vs 43.4, P < 0.05, CR small) and altered bowel habits (30.1 vs 40.7, P < 0.01, CR moderate) symptom scores. There was a lower prevalence of worrying (36.2% vs 60.5%, P < 0.05) and bloating (42.0% vs 56.2%, P < 0.05) among PD survivors with complications. Conclusions Post-PD complication rates were not associated with long-term global QoL or functionality, and may be associated with less severe pancreas-specific symptoms.

Abstract
INTRODUCTION Recent data suggests that infrarenal abdominal aortic aneurysm (AAA) endovascular repair (EVAR) with large diameter grafts (LGs) may have a higher risk of endoleak and reintervention. However, this has not been studied extensively for fenestrated endovascular aneurysm repair (fEVAR). We, therefore, sought to evaluate the outcomes of patients undergoing fEVAR with large-diameter endografts. METHODS Patients from the national Vascular Quality Initiative registry who underwent fEVAR for intact juxtarenal AAA were identified. Patients with genetic causes for aneurysms, those with prior aortic surgery, and those undergoing repair for symptomatic or ruptured aneurysms were excluded. Rates of endoleaks and reintervention at periprocedural and long-term follow-up timepoints (9-22 mo) were analyzed in grafts 32 mm or larger (LG) and were compared to those smaller than 32 mm (small diameter graft). RESULTS A total of 693 patients (22.8% LG) were identified. Overall, demographic variables were comparable except LG exhibited a more frequent history of coronary artery disease (32.9% versus 25.4%, P = 0.037). There were no significant differences in the rates of endoleak at procedural completion. Overall survival at 5 y was no different. The rate of reintervention at 1 y was also no different (log-rank P = 0.86). CONCLUSIONS While graft size appears to have an association with outcomes in infrarenal aneurysm repair, the same does not appear to be true for fEVAR. Further studies should evaluate the long-term outcomes associated with LG which could alter the approach to repair of AAA with large neck diameters traditionally treated with standard infrarenal EVAR.

Abstract
BACKGROUND Elective treatment options for aortic abdominal aneurysms include open repair or the less-invasive endovascular aortic aneurysm repair (EVAR). Recovery from EVAR is generally considered easier and faster than open repair. Despite this, EVAR remains a major procedure, and average return to preoperative quality of life is at least 3 months. The purpose of this study is to determine the safety and feasibility of multimodal prehabilitation, a multidisciplinary preoperative optimization intervention, in patients undergoing EVAR and its impact on perioperative functional capacity and quality of life. METHODS Candidates for EVAR with an infra-renal abdominal aortic aneurysm <7.5cm were invited to participate in a 6-week multimodal prehabilitation program that included (1) supervised and home-based exercise, (2) nutritional support, (3) psychosocial support, and (4) smoking cessation. Functional capacity and quality of life were assessed at baseline, before surgery and 6 weeks postoperatively. Recruitment rate, safety, and compliance were also assessed. RESULTS A total of 24 patients were included, 17 males (70%) and 7 females (30%). No adverse events occurred during the program. Compliance to each component of the program (median [Q1-Q3]) was 66% [67] for supervised training, 100% [67] for home-based training, and 100% [100] for nutrition. The multimodal prehabilitation program elicited a significant increase in functional capacity and quality of life preoperatively. CONCLUSION Multimodal prehabilitation for patients awaiting EVAR is feasible and safe. Multimodal prehabilitation improves both functional capacity and quality of life preoperatively. Further research is needed to assess the impact of multimodal prehabilitation on postoperative quality of life and functional capacity. CLINICAL IMPACT Multimodal prehabilitation is safe and feasible in patients awaiting endovascular aneurysm repair. The importance of this finding is that multimodal prehabilitation can be safely delivered preoperatively in patients awaiting EVAR. Although further research is needed, multimodal prehabilitation seems to improve preoperative functional capacity and quality of life. This could have an impact for the future implementation of prehabilitation interventions in order to increase functional reserve and quality of life preoperatively so that this high-risk population can cope better with the surgical stress and return to their normal life faster postoperatively.

Abstract
OBJECTIVES Survivorship encompasses the physical, psychological, social, functional, and economic experience of a living with a chronic condition for both the patient and their caregiver. It is made up of nine distinct domains and remains understudied in nononcological pathologies, including infrarenal abdominal aortic aneurysmal disease (AAA). This review aims to quantify the extent to which existing AAA literature addresses the burden of survivorship. METHODS The MEDLINE, EMBASE, and PsychINFO databases were searched from 1989 through September 2022. Randomized controlled trials, observational studies, and case series were included. Eligible studies had to detail outcomes related to survivorship in patients with AAA. Owing to the heterogeneity between studies and outcomes, no meta-analysis was conducted. Study quality was assessed with specific risk of bias tools. RESULTS A total of 158 studies were included. Of these, only five (treatment complications, physical functioning, comorbidities, caregivers, and mental health) of the nine domains of survivorship have been studied previously. The available evidence is of variable quality; most studies display a moderate to high risk of bias, are of an observational study design, are based within a limited number of countries, and consist of an insufficient follow-up period. The most frequent complication after EVAR was endoleak. EVAR is associated with poorer long-term outcomes compared with open surgical repair in most studies retrieved. EVAR showed better outcomes in regard to physical functioning in the short term, but this advantage was lost in the long term. The most common comorbidity studied was obesity. No significant differences were found between open surgical repair and EVAR in terms of impact on caregivers. Depression is associated with various comorbidities and increased the risk of a nonhospital discharge. CONCLUSIONS This review highlights the absence of robust evidence regarding survivorship in AAA. As a result, contemporary treatment guidelines rely on historic quality-of-life data that are narrow in scope and nonrepresentative of contemporary clinical practice. As such, there is an urgent need to reevaluate the aims and methodology associated with traditional quality-of-life research moving forward.

Abstract
A 67-year-old male patient required surgical management of an abdominal aortic aneurysm. A contrast-enhanced computed tomography showed a saccular infrarenal abdominal aortic aneurysm, with occlusion of the origins of the celiac artery, superior mesenteric artery, and inferior mesenteric artery. An aortography revealed large amounts of blood flow from capillaries around the abdominal aorta to the inferior mesenteric artery and retrograde blood flow to the meandering mesenteric artery through the superior rectal artery. Considering the risk of bowel ischemia, we performed endovascular aneurysm repair with mesenteric artery bypass. The operation was successful, and the postoperative course was uneventful. This procedure may be useful and less invasive.

Abstract
INTRODUCTION Clinical trials at the advent of endovascular aortic aneurysm repairs (EVARs) demonstrated improved early survival with EVAR compared to open repairs; however, characterizations of routine contemporary care have been limited. This study compares postoperative survival among Veterans in clinical care following abdominal aortic aneurysm (AAA) repair with EVAR versus open repairs since the widespread adoption of EVAR. MATERIALS AND METHODS This retrospective cohort analysis of Veterans with AAA repairs from 2007 to 2020 at Veterans Affairs (VA) facilities evaluated survival by a repair method. Administrative International Classification of Diseases 9/10 codes and sociodemographic characteristics from structured charting were used for characterization and adjusted analyses. Demographics were compared via Chi-squared and Wilcoxon rank-sum testing and mortality evaluated using Kaplan-Meier and Cox proportional hazard analyses. RESULTS Among 15,480 AAA repairs (3566 open, and 11,914 EVAR), patients receiving open repairs were younger with lower Charlson scores compared to EVARs. EVAR was associated with better survival until 2.4 y post-procedure. Mean long-term survival, however, was higher for open surgery (6.3 ± 3.8 versus 5.8 ± 3.1 y in EVAR). After adjustment for gender, race, and ethnicity, EVAR was associated with worse survival (mortality hazard ratio [HR] 1.17; 95% confidence interval [CI], 1.11-1.24) as was each increment in Charlson score (HR 1.11; CI 1.10-1.12), whereas service-connected care (HR 0.73; CI, 0.70-0.77) and age (HR 0.99; CI, 0.98-0.99) were associated with better survival. CONCLUSIONS In contemporary Veteran aneurysm repairs, although a higher early survival rate was observed in EVAR repairs, long-term survival was higher for open repairs. Service-connected care was independently associated with greater survival after aneurysm repair.

Abstract
Objectives: To determine the degree of long-term health-related quality of life (HRQoL) of patients undergoing surgery for abdominal aortic aneurysm (AAA) and to analyze the results according to the type of treatment, namely, open abdominal repair (OAR) or endoprosthesis (EVAR). Patients and Methods: This was a prospective cross-sectional observational study. Patients receiving intervention for AAA between January 2013 and December 2020 were included. The Spanish version of the SF-36 questionnaire was used. A single survey was performed on all patients, and the time elapsed since the intervention was recorded. Results: On all health scales and in the two groups of patients, the highest scores were recorded at six months postoperatively. At that time, the EVAR and OAR groups had similar values. Between 13 and 16 months postoperatively, EVAR patients presented a transient but significant decrease in their scores for physical function (p = 0.016), vitality (p = 0.035) and social function (p = 0.041). From that moment, there were progressive decreases in the scores of the two groups of patients on all the scales of the SF-36 questionnaire, although this trend was less pronounced in the OAR group. At 60 months after the intervention, the latter group showed significantly higher values than EVAR for physical function (p = 0.01), vitality (p = 0.032) and mental health (p = 0.029). Additionally, at 60 months after the intervention, the Sum of the psychological component (MCS) and Sum of the physical component (PCS) scores were significantly higher in the OAR group (p = 0.040 and p = 0.039, respectively). Conclusions: In the short term, patients treated for AAA by EVAR or OAR showed similar results on the SF-36 questionnaire. In the long term, patients treated by EVAR had lower scores on the physical function, vitality and mental health scales.

Abstract
Objectives This study aimed to compare the quality of life and cost effectiveness between endovascular aneurysm repair (EVAR) and open surgical repair (OSR) in young patients with abdominal aortic aneurysm (AAA). Design This was a single-center, observational, and retrospective study. Materials and methods A retrospective analysis was conducted of patients with AAA, who were <70 years old and underwent EVAR or OSR between January 2012 and October 2016. Only patients with aortic morphology that was suitable for EVAR were enrolled. Data on the complication rates, medical expenses, and expected quality-adjusted life years (QALYs) were collected, and the cost per QALY at three years was compared. Results Among 90 patients with aortic morphology who were eligible for EVAR, 37 and 53 patients underwent EVAR and OSR, respectively. No significant differences were observed in perioperative cardiovascular events and death between the two groups. However, during the follow-up period, patients undergoing OSR showed a significantly lower complication rate (hazard ratio [HR] = 0.11; P = .021). From the three-year cost-effectiveness analysis, the total sum of costs was significantly lower in the OSR group (P < .001) than that in the EVAR group, and the number of QALYs was superior in the OSR group (P = .013). The cost per QALY at three years was significantly lower in the OSR group than that in the EVAR group (mean: $4038 vs. $10 137; respectively; P < .001) Conclusions OSR had lower complication rates and better cost-effectiveness than EVAR Among young patients with feasible aortic anatomy.

Abstract
BACKGROUND Management of juxta-renal abdominal aortic aneurysms (JRAAA) remains challenging. Both open surgical and endovascular options are feasible, however, there is lack of level 1 evidence to support one modality over the other. Operative interventions frequently necessitate either open repair with a suprarenal clamp positioning (ORSRC) or complex endovascular repair (EVAR) with fenestrated (fEVAR) or parallel stent grafts (chEVAR). AIM The aim of this study was to compare the renal function deterioration and mortality between ORSRC and fEVAR in patients who were operated on for unruptured JRAAA at a tertiary centre. DESIGN This was a retrospective observational study of patients. SETTING Tertiary vascular unit in the United Kingdom. POPULATION Patients with unruptured juxta-renal AAA. METHODS A retrospective review of prospectively collected data was performed on patients who underwent repair for unruptured JRAAA between March 2008 and October 2019. Analysis of short and mid-term outcomes after ORSRC (occlusion of the aorta above at least one of the main renal arteries) and fEVAR was conducted. Patients who underwent open repair of JRAAA with an infrarenal clamp were excluded. Procedural data as well as data regarding complications was noted. Acute kidney injury (AKI) and chronic kidney disease were defined using the KDIGO criteria (Kidney Disease: Improving Global Outcomes). Renal impairment data up to 1 year and mortality up to 5 years was recorded. RESULTS During the study period, 162 patients who underwent JRAAA repair met the inclusion criteria (60.5% of them having ORSRC). Approximately, 85.8% of the population were males (80.6% in the open group compared to 93.7% in the endovascular group; p=0.019). The mean age for patients in the open group was 74.0 (SD=±5.5) years compared to 76.1 (SD=±7.2) years in the fEVAR group (p=0.035). More patients in the ORSRC group were symptomatic (18.4% versus 6.3% in the fEVAR group; p=0.028) and they also had larger aneurysms compared to the fEVAR group (66.9 (±12.7) mm versus 62.6 (±8.6) mm, respectively; p=0.021). In the ORSRC group, all patients required suprarenal clamping, with clamping above only one of the main renal arteries carried out in 43 patients (44.3%) of cases. At baseline, 37.0% and 44.5% of patients had CKD stage 3 or worse in ORSRC and fEVAR groups, respectively (p=0.759). Approximately 47.6% of patients having ORSRC had evidence of acute renal impairment on post-operative day 3 compared to 12.7% of those in the endovascular group (p<0.05). By 9-12 months, 54.6% of patients in the OR group had a CKD stage of 3 or worse, compared to 62.1% of patients in the fEVAR group (Pearson χ2, p=0.713). The median total length of stay (LOS) was 10 days for OR versus 6 days for fEVAR (p<0.05). Patients having fEVAR were more likely to require re-intervention (26.6% v/s 10.2%; p=0.006). Mortality at 30 days was 8.2% for ORSRC against 7.8% for complex EVAR (p=0.936). The corresponding figures at 1 and 5 years were 10.2% and 25.5% for ORSRC compared to 14.1% and 32.8% (p=0.456 and p=0.314, respectively). CONCLUSIONS In the context of JRAAA, patients receiving fEVAR procedures tended to be older, with a smaller diameter aneurysm. Postoperatively, fEVAR was associated with shorter hospitalisation and less risk of AKI in the immediate post-operative course, but had a greater likelihood of requiring re-intervention over time. Both interventions had similar rate of renal function deterioration at 1 year and the five year mortality rate was comparable.

[PMID: 33875325 DOI: 10.1016/j.ejvs.2021.02.047] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Revised: 02/05/2021] [Accepted: 02/23/2021] [Indexed: 10/21/2022]
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.

Cost-effectiveness of contrast-enhanced ultrasound for the detection of endovascular aneurysm repair-related endoleaks requiring treatment. J Vasc Surg 2020; 73:232-239.e2.

Abstract
OBJECTIVE Follow-up after endovascular aneurysm repair is necessary to detect potentially life-threatening complications such as endoleaks. Computed tomography angiography (CTA) or magnetic resonance angiography (MRA) is often used as standard of care for follow-up. Contrast-enhanced ultrasound (CEUS) has been shown to be a viable and fast real-time nonionizing imaging modality with equivalent diagnostic accuracy while also being superior to color Doppler ultrasound. The aim of this cost-utility analysis was to evaluate the cost-effectiveness of this imaging method in comparison to others for the evaluation of endoleaks requiring treatment. METHODS A decision model based on Markov simulations estimated lifetime costs and quality-adjusted life years (QALYs) associated with CTA, MRA, CEUS, and color Doppler ultrasound. Model input parameters were obtained from recent literature. The applied sensitivity and specificity values amounted to 90.5% and 100.0% for CTA, 96.0% and 100.0% for MRA, 94.0% and 95.0% for CEUS, and 82.0% and 93.0% for color Doppler ultrasound. Probabilistic and deterministic sensitivity analysis was performed to estimate uncertainty of model results. To evaluate cost-effectiveness, incremental cost-effectiveness ratios were reported as a measure representing the economic value of a strategy compared with an alternative. The willingness to pay was set to $100,000/QALY. RESULTS In the base-case scenario for a willingness to pay of $100,000 per QALY, CEUS was the most cost-effective of the four diagnostic strategies with estimated costs of $17,383 and effectiveness of 9.770 QALYs. CTA was estimated to result in lifetime costs of $17,679 with an expected effectiveness of 9.768 QALYs, whereas color Doppler ultrasound showed expected costs of $17,287 with 9.763 QALYs. Expected costs and effectiveness of MRA amounted to $17,945 and 9.771 QALYs each. Base-case estimates of the incremental cost-effectiveness ratios for CEUS vs color Doppler ultrasound equaled $14,173.52/QALY. CONCLUSIONS CEUS is a cost-effective imaging method for the evaluation of therapy-requiring endoleaks in endovascular aneurysm repair surveillance.

Abstract
Objectives Abdominal aortic aneurysms are conventionally treated by open repair surgery. While endovascular aortic repair improves survival in high-risk patients, younger patients (40–65 years) potentially at lower risk with asymptomatic abdominal aortic aneurysms undergoing endovascular aortic repair usually have poorer post-operative outcomes and require longer term follow-up. In this study, clinical data on younger patients were analyzed to investigate whether endovascular aortic repair leads to poorer short- and long-term outcomes. Methods This was a systematic review and meta-analysis of articles comparing clinical outcomes in patients aged 40–65 years undergoing open repair or endovascular aortic repair and published between 2000 and 2017. In-hospital mortality, long-term mortality, and post-operative complication data were retrieved from eligible studies and clinical outcomes were compared. Twenty-one retrospective cohort analyses were included, accounting for 250,837 patients (149,051 endovascular aortic repair; 101,786 open repair). Risk ratios were pooled using the DerSimonian and Laird random effects model. All statistical analyses were performed in Review Manager 5.3. Results Younger patients with asymptomatic abdominal aortic aneurysms undergoing endovascular aortic repair had a significantly reduced 30-day mortality (odds ratio (OR) = 0.40, 95% confidence intervals (CI) 0.28–0.57; p < 0.00001), long-term mortality (OR = 0.37, 95% CI 0.17–0.82; p = 0.01), incidence of reintervention (OR = 0.47, 95% CI 0.34–0.66; p < 0.0001), and incidence of renal failure (OR = 1.58, 95% CI 1.37–1.82; p < 0.00001). Conclusions Endovascular aortic repair may improve short- and long-term survival and reduce post-operative complications in younger patients with asymptomatic abdominal aortic aneurysms.

Abstract
Different surgical treatments for abdominal aortic aneurysm can lead to different perceptions of health and well-being. The aim of this study was to describe patients' well-being, sense of coherence (SOC), and experiences of surgery after open and endovascular treatment one month and one and 2 years after the procedure. Seventy six patients participated (40 open repair; 36 endovascular aneurysm repair). The study was conducted using the SOC questionnaire, and specific questions about patients' experiences of the surgical treatment and well-being. After 2 years, no patient regretted the operation or considered it to be the most difficult experience they had ever had. Twenty percent of the patients were worried about complications one month after the operation. Both groups experienced difficulty in returning to normal activity after surgery at one month. At one and 2 years after the surgery, patients in both groups stated that it was other things in life that affected their well-being. The endovascular aneurysm repair group reported a significant decrease in SOC from baseline until one year (P = .012) and 2 years (P = .033). The open repair group reported a significant decrease after one year (0.033). The operation did not affect patients' way of thinking about the disease. Patients in both groups stated that it was other circumstances in life that affected their well-being one and 2 years after the treatment, which could indicate that long-term follow-up would not be necessary from a patient perspective. The operation affects patients' well-being a short time after the operation.

Abstract
BACKGROUND Ruptured abdominal aortic aneurysm (AAA) is a common vascular emergency. The mortality from emergency endovascular repair may be much lower than the 40-50% reported for open surgery. OBJECTIVE To assess whether or not a strategy of endovascular repair compared with open repair reduces 30-day and mid-term mortality (including costs and cost-effectiveness) among patients with a suspected ruptured AAA. DESIGN Randomised controlled trial, with computer-generated telephone randomisation of participants in a 1 : 1 ratio, using variable block size, stratified by centre and without blinding. SETTING Vascular centres in the UK (n = 29) and Canada (n = 1) between 2009 and 2013. PARTICIPANTS A total of 613 eligible participants (480 men) with a ruptured aneurysm, clinically diagnosed at the trial centre. INTERVENTIONS A total of 316 participants were randomised to the endovascular strategy group (immediate computerised tomography followed by endovascular repair if anatomically suitable or, if not suitable, open repair) and 297 were randomised to the open repair group (computerised tomography optional). MAIN OUTCOME MEASURES The primary outcome measure was 30-day mortality, with 30-day reinterventions, costs and disposal as early secondary outcome measures. Later outcome measures included 1- and 3-year mortality, reinterventions, quality of life (QoL) and cost-effectiveness. RESULTS The 30-day mortality was 35.4% in the endovascular strategy group and 37.4% in the open repair group [odds ratio (OR) 0.92, 95% confidence interval (CI) 0.66 to 1.28; p = 0.62, and, after adjustment for age, sex and Hardman index, OR 0.94, 95% CI 0.67 to 1.33]. The endovascular strategy appeared to be more effective in women than in men (interaction test p = 0.02). More discharges in the endovascular strategy group (94%) than in the open repair group (77%) were directly to home (p < 0.001). Average 30-day costs were similar between groups, with the mean difference in costs being -£1186 (95% CI -£2997 to £625), favouring the endovascular strategy group. After 1 year, survival and reintervention rates were similar in the two groups, QoL (at both 3 and 12 months) was higher in the endovascular strategy group and the mean cost difference was -£2329 (95% CI -£5489 to £922). At 3 years, mortality was 48% and 56% in the endovascular strategy group and open repair group, respectively (OR 0.73, 95% CI 0.53 to 1.00; p = 0.053), with a stronger benefit for the endovascular strategy in the subgroup of 502 participants in whom repair was started for a proven rupture (OR 0.62, 95% CI 0.43 to 0.89; p = 0.009), whereas aneurysm-related reintervention rates were non-significantly higher in this group. At 3 years, considering all participants, there was a mean difference of 0.174 quality-adjusted life-years (QALYs) (95% CI 0.002 to 0.353 QALYs) and, among the endovascular strategy group, a cost difference of -£2605 (95% CI -£5966 to £702), leading to 88% of estimates in the cost-effectiveness plane being in the quadrant showing the endovascular strategy to be 'dominant'. LIMITATIONS Because of the pragmatic design of this trial, 33 participants in the endovascular strategy group and 26 in the open repair group breached randomisation allocation. CONCLUSIONS The endovascular strategy was not associated with a significant reduction in either 30-day mortality or cost but was associated with faster participant recovery. By 3 years, the endovascular strategy showed a survival and QALY gain and was highly likely to be cost-effective. Future research could include improving resuscitation for older persons with circulatory collapse, the impact of local anaesthesia and emergency consent procedures.

Abstract
BACKGROUND Malnutrition is frequent among vascular surgery patients, given their age, chronic comorbidities, and poor functional status, and it is believed to increase their operative risk. We aimed to assess the combined use of recent significant weight loss (>10% body mass) and serum albumin levels as a nutritional status index to predict outcomes. METHODS We analyzed vascular surgery data from the American College of Surgeons National Surgical Quality Improvement Program database (2005-2012; N = 238,082) to compare operative death (in-hospital and 30-day operative death) across eight nutritional status groups based on weight loss (yes/no) and albumin category: very low albumin level (VL-Alb; <2.50 g/dL), low albumin level (L-Alb; 2.50-3.39 g/dL), normal albumin level (N-Alb; 3.40-4.39 g/dL), and high albumin level (H-Alb; 4.40-5.40 g/dL). Risk-adjusted odds ratios (AOR) with 95% confidence intervals were estimated by multivariable logistic regression (N-Alb [no weight loss], reference). RESULTS The study population included 113,936 patients for whom albumin level was available (age, 67 ± 13 years; 60.2% male). Operative death was documented in 5160 (4.53%) patients. The eight-category nutritional status was more predictive of operative death than age alone (C statistic, 0.74 vs 0.63). A high discrimination multivariable model for operative death was derived (C statistic, 0.851). Low albumin level was associated with increased death that worsened in case of weight loss: VL-Alb + WL, AOR = 3.83 (3.03-4.83); VL-Alb, AOR = 3.36 (3.06-3.69); L-Alb + WL, AOR = 2.46 (1.98-3.05); and L-Alb, AOR = 1.99 (1.84-2.15). Weight loss was associated with increased death even if albumin level was normal: N-Alb + WL, AOR = 1.77 (1.34-2.35); and H-Alb + WL, AOR = 1.91 (0.69-5.31). H-Alb was protective (AOR = 0.65 [0.55-0.76]). CONCLUSIONS Nutritional status predicts outcomes of vascular surgery. Serum albumin level and weight loss should be incorporated in patients' risk stratification.

Abstract
Objective This study aims to compare open surgical and endovascular aneurysm repair
(EVAR) of abdominal aortic aneurysms in terms of their effects on quality of
life, using Short Form-36 (SF-36). Methods A total of 133 consecutive patients who underwent EVAR or open surgical
repair for infra-renal abdominal aorta aneurysm between January 2009 and
June 2014 were included in the study. Twenty-six (19.5%) patients died
during follow-up and were excluded from the analysis. Overall, 107 patients,
39 (36.4%) in the open repair group, and 68 (63.6%) in the EVAR group,
completed all follow-up visits and study assessments. Quality of life
assessments using SF-36 were performed before surgery and at post-operative
months 1, 6, and 12. Results The mean duration of follow-up was 29.55±19.95 months. At one month,
both physical and mental domains of the quality of life assessments favored
EVAR, while the two surgical approaches did not differ significantly at or
after six months postoperatively. Conclusion Despite anatomical advantages and acceptable mid-phase mortality in patients
with high- or medium-risk for open surgery, EVAR did not exhibit a quality
of life superiority over open surgery in terms of physical function and
patient comfort at or after postoperative six months.

Abstract
Vascular disease covers a wide range of conditions, including arterial, venous, and lymphatic disorders, with many of these being more common in the elderly. As the population ages, the incidence of vascular disease will increase, with a consequent increase in the requirement to manage both acute and chronic pain in this patient population. Pain management can be complex, as there are often multiple co-morbidities to be considered. An understanding of the underlying pain mechanisms is helpful in the logical direction of treatment, particularly in chronic pain states, such as phantom limb pain or complex regional pain syndrome. Acute pain management for vascular surgery presents a number of challenges, including coexisting anticoagulant medication, that may preclude the use of regional techniques. Within the limited evidence base, there is a suggestion that epidural analgesia provides better pain relief and reduced respiratory complications after major vascular surgery. For carotid endarterectomy, there is again some evidence supporting the use of local anaesthetic analgesia, either by infiltration or by superficial cervical plexus block. Chronic pain in vascular disease includes post-amputation pain, for which well-known risk factors include high pain levels before amputation and in the immediate postoperative period, emphasizing the importance of good pain control in the perioperative period. Complex regional pain syndrome is another challenging chronic pain syndrome with a wide variety of treatment options available, with the strongest evidence being for physical therapies. Further research is required to gain a better understanding of the underlying pathophysiological mechanisms in pain associated with vascular disease and the best analgesic approaches to manage it.

Abstract
Aortic aneurysms represent a major public health burden, and currently have no medical treatment options. The pathophysiology behind these aneurysms is complex and variable, depending on location and underlying cause, and generally involves progressive dysfunction of all elements of the aortic wall. Changes in smooth muscle behavior, endothelial signaling, extracellular matrix remodeling, and to a variable extent inflammatory signaling and cells, all contribute to the dilation of the aorta, ultimately resulting in high mortality and morbidity events including dissection and rupture. A large number of researchers have identified non-coding RNAs as crucial regulators of aortic aneurysm development, both in humans and in animal models. While most work to-date has focused on microRNAs, intriguing information has also begun to emerge regarding the role of long-non-coding RNAs. This review summarizes the currently available data regarding the involvement of non-coding RNAs in aneurysmal aortopathies. Going forward, these represent key potential therapeutic targets that might be leveraged in the future to slow or prevent aortic aneurysm formation, progression and rupture.

Abstract
Objective To assess the three year clinical outcomes and cost effectiveness of a strategy of endovascular repair (if aortic morphology is suitable, open repair if not) versus open repair for patients with suspected ruptured abdominal aortic aneurysm.Design Randomised controlled trial.Setting 30 vascular centres (29 in UK, one in Canada), 2009-16.Participants 613 eligible patients (480 men) with a clinical diagnosis of ruptured aneurysm, of whom 502 underwent emergency repair for rupture.Interventions 316 patients were randomised to an endovascular strategy (275 with confirmed rupture) and 297 to open repair (261 with confirmed rupture).Main outcome measures Mortality, with reinterventions after aneurysm repair, quality of life, and hospital costs to three years as secondary measures.Results The maximum follow-up for mortality was 7.1 years, with two patients in each group lost to follow-up by three years. After similar mortality by 90 days, in the mid-term (three months to three years) there were fewer deaths in the endovascular than the open repair group (hazard ratio 0.57, 95% confidence interval 0.36 to 0.90), leading to lower mortality at three years (48% v 56%), but by seven years mortality was about 60% in each group (hazard ratio 0.92, 0.75 to 1.13). Results for the 502 patients with repaired ruptures were more pronounced: three year mortality was lower in the endovascular strategy group (42% v 54%; odds ratio 0.62, 0.43 to 0.88), but after seven years there was no clear difference between the groups (hazard ratio 0.86, 0.68 to 1.08). Reintervention rates up to three years were not significantly different between the randomised groups (hazard ratio 1.02, 0.79 to 1.32); the initial rapid rate of reinterventions was followed by a much slower mid-term reintervention rate in both groups. The early higher average quality of life in the endovascular strategy versus open repair group, coupled with the lower mortality at three years, led to a gain in average quality adjusted life years (QALYs) at three years of 0.17 (95% confidence interval 0.00 to 0.33). The endovascular strategy group spent fewer days in hospital and had lower average costs of -£2605 (95% confidence interval -£5966 to £702) (about €2813; $3439). The probability that the endovascular strategy is cost effective was >90% at all levels of willingness to pay for a QALY gain.Conclusions At three years, compared with open repair, an endovascular strategy for suspected ruptured abdominal aortic aneurysm was associated with a survival advantage, a gain in QALYs, similar levels of reintervention, and reduced costs, and this strategy was cost effective. These findings support the increasing use of an endovascular strategy, with wider availability of emergency endovascular repair.Trial registration Current Controlled Trials ISRCTN48334791; ClinicalTrials NCT00746122.

Abstract
OBJECTIVE Our aim was to assess quality of life (QOL) and functionality in a large cohort of patients ≥5-years after pancreaticoduodenectomy (PD). BACKGROUND Long-term QOL outcomes after PD for benign or malignant disease are largely undocumented. METHODS We administered the EORTC QLQ-C30 questionnaire to patients who underwent PD for neoplasms from 1998 to 2011 and compared their scores with an age- and sex-matched normal population. Clinical relevance (CR) of differences was scored as small (5-10), moderate (10-20), or large (>20) based on validated interpretation of clinically important differences. RESULTS Of 305 PD survivors, 245 (80.3%) responded, of whom 157 (64.1%) underwent PD for nonmalignant lesions. Median follow-up was 9.1 years (range 5.1 -21.2 yrs). New-onset diabetes developed in 10.6%; 50.4% reported taking pancreatic enzymes; 54.6% reported needing antacids. Compared with the age- and sex-adjusted controls, PD survivors demonstrated higher global QOL (78.7 vs 69.7, CR small, P < 0.001), physical (86.7 vs 77.9, CR small, P < 0.001) and role-functioning scores (86.3 vs 74.1, CR medium, P < 0.001). Using linear regression and adjusting for socioeconomic variables, there were no differences in QOL or functional scores in the benign versus malignant subgroups. Older age at operation was associated with worse physical-functioning (-0.4/yr, P = 0.008). Taking pancrelipase (-6.8, P = 0.035) or antacids (-6.3, P = 0.044) were both associated with lower social-functioning scores. CONCLUSIONS Patients who had a PD demonstrated better global QOL, physical- and role-functioning scores at 5-years when compared with age- and sex-matched controls. Approximately half of the patients required pancreatic enzyme replacement, while only 11% developed new-onset diabetes.

Abstract
Objectives To evaluate long-term outcome and quality of life after open and endovascular repair of ruptured abdominal aortic aneurysms. Methods All consecutive ruptured abdominal aortic aneurysm patients at the St. Antonius Hospital treated for ruptured abdominal aortic aneurysm between January 2005 and January 2015 were included. Mortality, morbidity, and re-interventions within 30 days and during follow-up were registered. Quality of life was measured with Short Form-36 questionnaire among survivors. Additional subgroup analysis between open repair and endovascular repair was performed. Results A total of 192 patients with ruptured abdominal aortic aneurysm were included: 76.6% (147/192) underwent open repair and 23.4% (45/192) endovascular repair. All-cause 30-day mortality rate was 31.3% (60/192), and 30-day morbidity rate was 70.3% (135/192). Median stay at the intensive care unit was two days for endovascular repair and four days for open repair ( p = 0.002). No other statistically significant differences between endovascular repair and open repair were observed. After a mean follow-up period of 62 months (range 9–126), 72.4% (76/105) of the responders had equivalent Short Form-36 scores as compared to the age-matched general Dutch population, and 84.2% (64/76) of the responders would choose surgery again if they would have a ruptured abdominal aortic aneurysm. Conclusions Survivors of ruptured abdominal aortic aneurysm have similar long-term quality of life scores compared to the age-matched general population. The majority of all survivors would choose to undergo acute abdominal aortic aneurysm repair again.

Abstract
Introduction The aim of this review is to assess if late mortality after endovascular repair (EVAR) of abdominal aortic aneurysms (AAA) is a real problem, and whether it could be an issue in the case of medical litigation. Material and methods A review of all English language literature was performed on PubMed web-site, looking for all papers reporting EVAR long-term mortality rate. EVAR performances were reviewed also from an ethical and medico-legal point of view, based on current Italian laws. Results Mono-centric studies, and international registers suggest that today EVAR offers similar (if not better) results than open repair (OR) in the treatment of AAAs with standard and complex anatomies, even if performed outside the devices-specific instructions for use. In contrast, large randomized trials, and consequently current guidelines, suggest that EVAR still has an ancillary role compared to OR, only to be used for highly selected patients. Recently, specific litigation cases on surgical options related to the treatment of aortic aneurysms has developed. The informed consent process needs to include not only mortality and major complications related to the procedure but also the chance of patients' outcomes. For those reasons, the generic nature of informed consent has been criticized. Conclusions No conclusive data is currently available to assess the initial question of late mortality after EVAR but results are still improving. In the meantime, widespread use of EVAR as first choice for treating AAA may only be acceptable in high-volume centres validating their results by a strict follow up protocol. The long-term results after endovascular repair (EVAR) for abdominal aortic aneurysms (AAA) are still considered one of the main limitations of this treatment option. This paper is a comprehensive review of the current literature on long-term mortality after EVAR procedures. An analysis on informed consent for EVAR from a non-surgical point of view is reported for the very first time.

Abstract
Although many trials have evaluated abdominal aortic aneurysm (AAA) repair, the impact of these procedures on the functional status of frail elderly patients is not well-described. The effects of elective open AAA repair (OAR) and endovascular AAA repair (EVAR) and comorbidities were evaluated for their impact on functional trajectories after discharge. Medicare inpatient claims were linked with nursing home assessment data to identify elective admissions for OAR and EVAR. A functional score (range, 0-28; higher scores indicate greater impairment) was calculated before and after interventions. Logistic regression was used to develop a propensity score for receiving EVAR because residents were not randomized. Hierarchical linear modeling determined the effect of surgery on residents' function, controlling for prehospital function, hospital length of stay (LOS), stroke, and the propensity score.Fifty-two residents underwent OAR and 161 underwent EVAR. Most (65.3%) were men and 62.0% were from 76 to 85 years old. Mean LOS was 8.3 days for OAR and 5.1 days for EVAR. Of the residents, 47.4% had good prehospital function (activities of daily living [ADL] score of 0-10), and 48.4% were moderately impaired (ADL score of 11-20). Higher baseline ADL score, increased LOS, and stroke were associated with worse trajectories. Procedure type was not significantly related to postoperative function or the subsequent rate of improvement. OAR and EVAR were associated with similar initial declines and comparable postoperative trajectories, suggesting that less invasive EVAR was not associated with improved functional preservation compared with OAR. LOS was found to be higher than expected in the frail elderly after EVAR; longer stays were associated with poorer functional trajectories. Higher baseline ADL scores were significantly associated with inferior functional status after both procedures. Evaluation of preoperative function may assist physicians in predicting outcomes in this high-risk population.

Abstract
Short-term and midterm clinical outcomes after endovascular repair of abdominal aortic aneurysms (AAAs) have been well documented. Evaluation of longer term outcomes is now possible. Here we describe our initial 100 high-risk patients treated with endovascular aneurysm repair (EVAR), all with a minimum of 5 years of follow-up. A retrospective review of prospectively recorded data in a departmental database was undertaken for the first 100 consecutive EVAR patients with a minimum of 5 years (range, 60-105 months) of follow-up performed between December 1997 and June 2001. Information was obtained from surgical follow-up visits and family doctors' offices. Endovascular repair of AAA in high-risk patients can be achieved with acceptably low postoperative mortality and morbidity. Longer term results in this high-risk cohort suggest that EVAR is effective in preventing aneurysm-related deaths at 5 years and beyond. All late mortalities were due to patients' comorbid diseases.

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

Abstract
Abdominal aortic aneurysm (AAA) is a common and deadly problem. The aortic diameter increases in association with a complex remodeling process that includes changes in the structure and content of key proteins, elastin and collagen. As these changes occur, the tissue mechanical properties also change. The natural history of AAA is progressive enlargement to a point of mechanical tissue failure, typically followed by death. Currently, the marker used to predict the risk of impending rupture is the largest transverse diameter. After reaching a diameter threshold of 5.5 cm, the aneurysm is surgically repaired. This criterion does not consider any patient-specific information or the known heterogeneity of the aneurysm that may, in some cases, lead to rupture before the aneurysm reaches the standard intervention threshold. Conversely, in many patients, continued observation beyond this threshold is safe. Although no medical treatment is yet approved, doxycycline has been shown to greatly reduce aortic aneurysm growth in animal models and has been shown to slow growth in several small clinical trials. Although larger prospective randomized trials are needed, one unknown is what effect doxycycline has on the structural integrity of the aortic wall. That is, does slowed aneurysm growth by doxycycline treatments, in fact, prevent rupture, or does the wall continue to weaken and the aneurysm instead ruptures at a smaller diameter? Research has begun to answer these questions before a large clinical trial begins.

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

Abstract
Abstract
Background
The aim of this study was to present preliminary data on quality of life (QoL), symptoms and treatment satisfaction gathered using three new abdominal aortic aneurysm (AAA)-specific patient-reported outcome measures (PROMs).
Methods
Patients with AAA were recruited from five National Health Service Trusts to complete the three new PROMs: the AneurysmDQoL, AneurysmSRQ and AneurysmTSQ. Patients were either under surveillance or had undergone AAA repair (open or endovascular) during the preceding 24 months. Data were initially collected as part of a study assessing the psychometric properties of the new measures, before being used in the observational analysis of outcomes presented here.
Results
Results, although largely non-significant, showed interesting trends. The impact of AAA repair on QoL appeared to worsen progressively after open repair (OR) and improve progressively after endovascular aneurysm repair (EVAR). Conversely, symptoms seemed to become progressively worse after EVAR and progressively better after OR. Information and understanding were key sources of dissatisfaction before the intervention, whereas postoperative dissatisfaction was related to bother from symptoms, follow-up and feedback about scan results.
Conclusion
Although a larger, prospective data set is necessary to explore outcomes more fully with the new AAA-specific PROMs, the observational data presented here suggest there may be clinically important differences in the symptoms, impact on QoL and treatment satisfaction associated with OR and EVAR.

Abstract
The aim of this study was to assess the hemodynamic performance of a patient-specific fenestrated stent graft (FSG) under different physiological conditions, including normal resting, hypertension, and hypertension with moderate lower limb exercise. A patient-specific FSG model was constructed from computed tomography images and was discretized into a fine unstructured mesh comprising tetrahedral and prism elements. Blood flow was simulated using Navier-Stokes equations, and physiologically realistic boundary conditions were utilized to yield clinically relevant results. For a given cycle-averaged inflow of 2.08 L/min at normal resting and hypertension conditions, approximately 25% of flow was channeled into each renal artery. When hypertension was combined with exercise, the cycle-averaged inflow increased to 6.39 L/min but only 6.29% of this was channeled into each renal artery, which led to a 438.46% increase in the iliac flow. For all the simulated scenarios and throughout the cardiac cycle, the instantaneous flow streamlines in the FSG were well organized without any notable flow recirculation. This well-organized flow led to low values of endothelial cell activation potential, which is a hemodynamic metric used to identify regions at risk of thrombosis. The displacement forces acting on the FSG varied with the physiological conditions, and the cycle-averaged displacement force at normal rest, hypertension, and hypertension with exercise was 6.46, 8.77, and 8.99 N, respectively. The numerical results from this study suggest that the analyzed FSG can maintain sufficient blood perfusion to the end organs at all the simulated conditions. Even though the FSG was found to have a low risk of thrombosis at rest and hypertension, this risk can be reduced even further with moderate lower limb exercise.

Abstract
Abstract
Background
No condition-specific patient-reported outcome measures exist for patients with abdominal aortic aneurysm (AAA). The aim of this work was to develop three questionnaires to assess quality of life (QoL), symptoms and treatment satisfaction in patients with AAA.
Methods
Semistructured interview techniques were used to explore patients' experiences of having an AAA in a series of focus groups and in-depth interviews. The information gathered was used to inform design and selection of items for the new tools; the overall structure of the new questionnaires was based on tools developed previously for patients with diabetes and other conditions.
Results
Fifty-four patients (51 men, 3 women; mean age 71·9 years) were recruited from four NHS Trusts to participate in focus groups or interviews, either while under surveillance, or following AAA repair (using open or endovascular techniques). The Aneurysm-Dependent Quality of Life Questionnaire (AneurysmDQoL) is an individualized measure of the impact of AAA on patients' QoL. Twenty-three domains were chosen specifically for their relevance to patients with AAA, with a further two overview items to assess overall QoL and the impact of AAA on QoL. The Aneurysm Symptom Rating Questionnaire (AneurysmSRQ) is a 44-item measure assessing physical and psychological symptoms reported by patients with AAA. The Aneurysm Treatment Satisfaction Questionnaire (AneurysmTSQ) contains 11 items, suitable for patients before and after surgical intervention.
Conclusion
The iterative development process reported here has confirmed that these three new tools have good face and content validity for patients with AAA.

Abstract
Currently, studies connected with Computational Fluid Dynamic (CFD) techniques focus on assessing hemodynamic of blood flow in vessels in different conditions e.g. after stent-graft’s placement. The paper propose a novel method of standardization of results obtained from calculations of stent-grafts' “pushing forces” (cumulative WSS—Wall Shear Stress), and describes its usefulness in diagnostic process. AngioCT data from 27 patients were used to reconstruct 3D geometries of stent-grafts which next were used to create respective reference cylinders. We made an assumption that both the side surface and the height of a stent-graft and a reference cylinder were equal. The proposed algorithm in conjunction with a stent-graft “pushing forces” on an implant wall, allowed us to determine which spatial configuration of a stent-graft predispose to the higher risk of its migration. For stent-grafts close to cylindrical shape (shape factor φ close to 1) WSS value was about 267Pa, while for stent-grafts different from cylindrical shape (φ close to 2) WSS value was about 635Pa. It was also noticed that deformation in the stent-graft’s bifurcation part impaired blood flow hemodynamic. Concluding the proposed algorithm of standardization proved its usefulness in estimating the WSS values that may be useful in diagnostic process. Angular bends or tortuosity in bifurcations of an aortic implant should be considered in further studies of estimation of the risk of implantation failure.

Abstract
Abstract
Background
Long-term survival is similar after open or endovascular repair of abdominal aortic aneurysm. Few data exist on the effect of either procedure on long-term health-related quality of life (HRQoL) and health status.
Methods
Patients enrolled in a multicentre randomized clinical trial (DREAM trial; 2000–2003) in Europe of open repair versus endovascular repair (EVAR) of abdominal aortic aneurysm were asked to complete questionnaires on health status and HRQoL. HRQoL scores were assessed at baseline and at 13 time points thereafter, using generic tools, the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36®) and EuroQol 5D (EQ-5D™). Physical (PCS) and mental component summary scores were also calculated. Follow-up was 5 years.
Results
Some 332 of 351 patients enrolled in the trial returned questionnaires. More than 70 per cent of questionnaires were returned at each time point. Both surgical interventions had a short-term negative effect on HRQoL and health status. This was less severe in the EVAR group than in the open repair group. In the longer term the physical domains of SF-36® favoured open repair: mean difference in PCS score between open repair and EVAR −1·98 (95 per cent c.i. −3·56 to −0·41). EQ-5D™ descriptive and EQ-5D™ visual analogue scale scores for open repair were also superior to those for EVAR after the initial 6-week interval: mean difference −0·06 (−0·10 to −0·02) and −4·09 (−6·91 to −1·27) respectively.
Conclusion
In this study EVAR appeared to be associated with less severe disruption to HRQoL and health status in the short term. However, during longer-term follow-up to 5 years, patients receiving open repair appeared to have improved quality of life and health status.

Abstract
The use of stent grafts for endovascular aortic repair has become an important treatment option for aortic aneurysms requiring surgery. This treatment has achieved excellent outcomes; however, problems like type 1 endoleaks and stent graft migration remain. Bio stent grafts (BSGs), which are self-expanding stents covered with connective tissue, were previously developed using "in-body tissue architecture" technology. We assessed their early adaptation to the aorta after transcatheter implantation in a beagle model. BSGs were prepared by subcutaneous embedding of acryl rods mounted with self-expanding nitinol stents in three beagles for 4 weeks (n = 3/dog). The BSGs were implanted as allografts into infrarenal abdominal aortas via the femoral artery of three other beagles. After 1 month of implantation, aortography revealed no stenosis or aneurysmal changes. The luminal surface of the BSGs was completely covered with neointimal tissue, including endothelialization, without any thrombus formation. The cover tissue could fuse the luminal surface of the native aorta with tight conjunctions even at both ends of the stents, resulting in complete impregnation of the strut into the reconstructed vascular wall, which is expected to prevent endoleaks and migration in clinical applications.

Abstract
In this study, we aimed to describe the development of tissue-engineered self-expandable aortic stent grafts (Bio stent graft) using in-body tissue architecture technology in beagles and to determine its mechanical and histological properties. The preparation mold was assembled by insertion of an acryl rod (outer diameter, 8.6 mm; length, 40 mm) into a self-expanding nitinol stent (internal diameter, 9.0 mm; length, 35 mm). The molds (n = 6) were embedded into the subcutaneous pouches of three beagles for 4 weeks. After harvesting and removing each rod, the excessive fragile tissue connected around the molds was trimmed, and thus tubular autologous connective tissues with the stent were obtained for use as Bio stent grafts (outer diameter, approximately 9.3 mm in all molds). The stent strut was completely surrounded by the dense collagenous membrane (thickness, ∼150 µm). The Bio stent graft luminal surface was extremely flat and smooth. The graft wall of the Bio stent graft possessed an elastic modulus that was almost two times higher than that of the native beagle abdominal aorta. This Bio stent graft is expected to exhibit excellent biocompatibility after being implanted in the aorta, which may reduce the risk of type 1 endoleaks or migration.

Abstract
BACKGROUND An abnormal dilatation of the abdominal aorta is referred to as an abdominal aortic aneurysm (AAA). Due to the risk of rupture, surgical repair is offered electively to individuals with aneurysms greater than 5.5 cm in size. Traditionally, conventional open surgical repair (OSR) was considered the first choice approach. However, over the past two decades endovascular aneurysm repair (EVAR) has gained popularity as a treatment option. This article intends to review the role of EVAR in the management of elective AAA. OBJECTIVES To assess the effectiveness of EVAR versus conventional OSR in individuals with AAA considered fit for surgery, and EVAR versus best medical care in those considered unfit for surgery. This was determined by the effect on short, intermediate and long-term mortality, endograft related complications, re-intervention rates and major complications. SEARCH METHODS The Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator (TSC) searched the Specialised Register (January 2013) and the Cochrane Central Register of Controlled Trials (CENTRAL) (2012, Issue 12). The TSC also searched trial databases for details of ongoing or unpublished studies. SELECTION CRITERIA Prospective randomised controlled trials (RCTs) comparing EVAR with OSR in individuals with AAA considered fit for surgery. and comparing EVAR with best medical care in individuals considered unfit for surgery. We excluded studies with inadequate data or using an inadequate randomisation technique. DATA COLLECTION AND ANALYSIS Three reviewers independently evaluated trials for appropriateness for inclusion and extracted data using pro forma designed by the Cochrane PVD Group. We assessed the quality of trials using The Cochrane Collaboration's 'Risk of bias' tool. We entered collected data in to Review Manager (version 5.2.3) for analysis. Where direct comparisons could be made, we determined odds ratios (OR). We tested studies for heterogeneity and, when present, we used a random-effects model; otherwise we used a fixed-effect model. We tabulated data that could not be collated. MAIN RESULTS Four high-quality trials comparing EVAR with OSR (n = 2790) and one high-quality trial comparing EVAR with no intervention (n = 404) fulfilled the inclusion criteria. In individuals considered fit for surgery, a pooled analysis, including 1362 individuals randomised to EVAR and 1361 randomised to OSR, found short-term mortality (including 30-day or inhospital mortality, excluding deaths prior to intervention) with EVAR to be significantly lower than with OSR (1.4% versus 4.2%, OR 0.33, 95% confidence interval (CI) 0.20 to 0.55; P < 0.0001). Using intention-to-treat analysis (ITT) there was no significant difference in mortality at intermediate follow-up (up to four years from randomisation), with 221 (15.8%) and 237 (17%) deaths in the EVAR (n = 1393) and OSR (n = 1390) groups, respectively (OR 0.92, 95% CI 0.75 to 1.12; P = 0.40). There was also no significant difference in long-term mortality (beyond four years), with 464 (37.3%) deaths in the EVAR and 470 (37.8%) deaths in the OSR group (OR 0.98, 95% CI 0.83 to 1.15; P = 0.78). Similarly, there was no significant difference in aneurysm-related mortality between groups, either at the intermediate- or long-term follow up.Studies showed that both EVAR and OSR were associated with similar incidences of cardiac deaths (OR 1.14, 95% CI 0.86 to 1.52; P = 0.36) and fatal stroke rate (OR 0.81, 95% CI 0.42 to 1.55; P = 0.52). The long-term reintervention rate was significantly higher in the EVAR group than in the OSR group (OR 1.98, 95% CI 1.12 to 3.51; P = 0.02; I(2) = 85%). Results of the reintervention analysis should be interpreted with caution due to significant heterogeneity. Operative complications, health-related quality of life and sexual dysfunction were generally comparable between the EVAR and OSR groups. However, there was a slightly higher incidence of pulmonary complications in the OSR group compared with the EVAR group (OR 0.36, 95% CI 0.17 to 0.75; P = 0.006).In individuals considered unfit for conventional OSR, the one included trial found no difference between the EVAR and no-intervention groups with regard to all-cause mortality at final follow up, with 21.0 deaths per 100 person-years in the EVAR group and 22.1 deaths per 100 person years in the no-intervention group (adjusted hazard ratio (HR) with EVAR 0.99, 95% CI 0.78 to 1.27; P = 0.97). Aneurysm-related deaths were, however, significantly higher in the no-intervention group than in the EVAR group (adjusted HR 0.53, 95% CI 0.32 to 0.89; P = 0.02). There was no difference in myocardial events (HR 1.07, 95% CI 0.60 to 1.91) between the groups in this study. AUTHORS' CONCLUSIONS In individuals considered fit for conventional surgery, EVAR was associated with lower short-term mortality than OSR. However, this benefit from EVAR did not persist at the intermediate- and long-term follow ups. Individuals undergoing EVAR had a higher reintervention rate than those undergoing OSR. Most of the reinterventions undertaken following EVAR, however, were catheter-based interventions associated with low mortality. Operative complications, health-related quality of life and sexual dysfunction were generally comparable between EVAR and OSR. However, there was a slightly higher incidence of pulmonary complications in the OSR group than in the EVAR group.In individuals considered unfit for open surgery, the results of a single trial found no overall short- or long-term benefits of EVAR over no intervention with regard to all-cause mortality, but individuals may differ and individual preferences should always be taken into account.

Abstract
INTRODUCTION In patients with large abdominal aortic aneurysm (AAA), open surgical or endovascular aneurysm repair procedures are often used to minimise the risk of aneurysm-related rupture and death; however, aneurysm repair itself carries a high risk. Low cardiopulmonary fitness is associated with an increased risk of early post-operative complications and death following elective AAA repair. Therefore, fitness should be enhanced before aneurysm repair. High-intensity interval exercise training (HIT) is a potent, time-efficient strategy for enhancing cardiopulmonary fitness. Here, we describe a feasibility study for a definitive trial of a pre-operative HIT intervention to improve post-operative outcomes in patients undergoing elective AAA repair. METHODS AND ANALYSIS A minimum of 50 patients awaiting elective repair of a 5.5-7.0 cm infrarenal AAA will be allocated by minimisation to HIT or usual care control in a 1:1 ratio. The patients allocated to HIT will complete three hospital-based exercise sessions per week, for 4 weeks. Each session will include 2 or 4 min of high-intensity stationary cycling followed by the same duration of easy cycling or passive recovery, repeated until a total of 16 min of high-intensity exercise is accumulated. Outcomes to be assessed before randomisation and 24-48 h before aneurysm repair include cardiopulmonary fitness, maximum AAA diameter and health-related quality of life. In the post-operative period, we will record destination (ward or critical care unit), organ-specific morbidity, mortality and the durations of critical care and hospital stay. Twelve weeks after the discharge, participants will be interviewed to reassess quality of life and determine post-discharge healthcare utilisation. The costs associated with the exercise intervention and healthcare utilisation will be calculated. ETHICS AND DISSEMINATION Ethics approval was secured through Sunderland Research Ethics Committee. The findings of the trial will be disseminated through peer-reviewed journals, and national and international presentations. TRIAL REGISTRATION Current Controlled Trials ISRCTN09433624.

Abstract
BACKGROUND While aneurysm neck length, angulation and width have all been previously assessed in endovascular abdominal aortic aneurysm repair (EVAR), aneurysm neck shape has not been considered. AIMS To analyse the influence of aneurysm neck morphology on outcome following EVAR. METHODS Aneurysm neck morphology in 70 patients undergoing EVAR from April 2001 to May 2004 was determined using pre-operative CT scans and graft plans. Necks were classified as flared, parallel, irregular, conical, barrel or hourglass. End-points were death,Type I endoleak and graft migration. RESULTS Forty-six per cent of necks were flared, 34% parallel, 9% irregular, 6% conical, 3% barrel and 3% hourglass. Mean follow-up was 20.2 months (range 4-35). There was one Type I endoleak and one graft migration. There were no aneurysm related deaths. CONCLUSIONS Assessment of aneurysm neck morphology should be part of the routine preoperative workup for EVAR. A classification system of AAA necks is suggested to facilitate this.
