Abstract
OBJECTIVE The objective of this study was to investigate changes in health-related quality of life (QOL) in patients treated for pararenal aortic aneurysms (PAAs) and thoracoabdominal aortic aneurysms (TAAAs) with fenestrated-branched endovascular aneurysm repair (F-BEVAR). METHODS A total of 159 consecutive patients (70% male; mean age, 75 ± 7 years) were enrolled in a prospective, nonrandomized single-center study using manufactured F-BEVAR (2013-2016). All patients were observed for at least 12 months (mean follow-up time, 27 ± 12 months). Patients' health-related QOL was assessed using the 36-Item Short Form Health Survey questionnaire at baseline (N = 159), 6 to 8 weeks (n = 136), 6 months (n = 129), and 12 months (n = 123). Physical component scores (PCSs) and mental component scores (MCSs) were compared with historical results of patients enrolled in the endovascular aneurysm repair (EVAR) 1 trial who were treated by standard EVAR for simple infrarenal abdominal aortic aneurysms. RESULTS There were 57 patients with PAAs and 102 patients with TAAAs (50 extent IV and 52 extent I-III TAAAs). There were no 30-day deaths, in-hospital deaths, conversions to open surgery, or aorta-related deaths. Survival was 96% at 1 year and 87% at 2 years. Major adverse events occurred in 18% of patients, and 1-year reintervention rate was 14%. There were no statistically significant differences between the groups in 30-day outcomes. Patients treated for TAAAs had lower baseline scores compared with those treated for PAAs (P < .05). PCS declined significantly 6 to 8 weeks after F-BEVAR in both groups and returned to baseline values at 12 months in the PAA group but not in the TAAA group. Patients with TAAAs had significantly lower PCSs at 12 months compared with those with PAAs (P < .001). There was no decline in mean MCS. Major adverse events were associated with decline in PCS assessed at 6 to 8 weeks (P = .021) but not in the subsequent evaluations. Reinterventions had no effect on PCS or MCS. Overall, patients treated by F-BEVAR had similar changes in QOL measures as those who underwent standard EVAR in the EVAR 1 trial, except for lower PCS in TAAA patients at 12 months. CONCLUSIONS Patients treated for TAAAs had lower scores at baseline in their physical aspect of health-related QOL. F-BEVAR was associated with significant decline in PCSs in both groups, which improved after 2 months and returned to baseline values at 12 months in patients with PAAs but not in those with TAAAs. Patients treated for PAAs had similar changes in QOL compared with those treated for infrarenal aortic aneurysms with standard EVAR.

Abstract
An abdominal aortic aneurysm (AAA) is a localized dilatation of the infrarenal aorta. AAA is a multifactorial disease, and genetic and environmental factors play a part; smoking, male sex and a positive family history are the most important risk factors, and AAA is most common in men >65 years of age. AAA results from changes in the aortic wall structure, including thinning of the media and adventitia due to the loss of vascular smooth muscle cells and degradation of the extracellular matrix. If the mechanical stress of the blood pressure acting on the wall exceeds the wall strength, the AAA ruptures, causing life-threatening intra-abdominal haemorrhage - the mortality for patients with ruptured AAA is 65-85%. Although AAAs of any size can rupture, the risk of rupture increases with diameter. Intact AAAs are typically asymptomatic, and in settings where screening programmes with ultrasonography are not implemented, most cases are diagnosed incidentally. Modern functional imaging techniques (PET, CT and MRI) may help to assess rupture risk. Elective repair of AAA with open surgery or endovascular aortic repair (EVAR) should be considered to prevent AAA rupture, although the morbidity and mortality associated with both techniques remain non-negligible.

Abstract
OBJECTIVE Although lifelong surveillance is recommended by the Society for Vascular Surgery for patients undergoing endovascular aneurysm repair (EVAR) reported that compliance with long-term follow-up has been poor. We sought to identify factors that predict compliance with EVAR surveillance through analysis of patient variables and post-EVAR questionnaire results. METHODS We analyzed 28 patient variables gathered from our computerized registry, patient charts, and phone questionnaires of patients who underwent EVAR between January 1, 2010, and December 31, 2014. These factors included patient demographics, education, postoperative complications, satisfaction with vascular surgery care, transportation mode, distance to our medical center, and living situation. Compliance was defined as a patient who underwent the most recent recommended follow-up surveillance study within the prescribed timeframe. Post-EVAR surveillance protocol consisted of office evaluation and duplex ultrasound examination performed in our accredited noninvasive vascular laboratory at 1 week, 6 months, then annually. Computed tomography angiography was obtained only if duplex ultrasound examination suggested endoleak, sac enlargement of more than 5 mm, or a failing limb. RESULTS Of 144 patients who underwent EVAR during this time period, 89 patients (62%) were compliant with the most recent recommended follow-up study. One hundred two patients completed the questionnaire or their families did if patients died or were incapacitated. Of those, 80 were compliant with follow-up and 22 were not. Based on the questionnaires of these 102 patients, estimated compliance at 3 years after EVAR was 69.6 ± 6.0% based on Kaplan-Meier analysis. In the compliant vs noncompliant groups, the estimated 3-year survival rate was 93.2 ± 3.4% vs 52.4 ± 12.7%, respectively (P < .001), and the estimated 5-year survival rate was 83.1 ± 6.4% vs 34.4 ± 13.4%, respectively (P < .001), respectively. However, none of the mortalities observed in the noncompliant group were aneurysm related. Adverse neurologic events after EVAR demonstrated a trend predicting noncompliance after 5 years based on multivariate Cox regression analysis (hazard ratio [HR], 2.57; 95% confidence interval [CI], 0.95-6.90; P = .062). Patient dissatisfaction with their vascular surgeon and hospital care predicted noncompliance with recommended postoperative surveillance (HR, 5.0; 95% CI, 1.52-16.7; P = .008). College education or higher was associated with compliance (HR, 0.28; 95% CI, 0.06-1.23; P = .092). No other variables, including postoperative complications or distance from the hospital, predicted follow-up noncompliance. CONCLUSIONS Patient satisfaction with their vascular surgeon and hospital experience predicted compliance with post-EVAR surveillance regardless of postoperative complications. Noncompliant patients had decreased survival, but mortality and surveillance noncompliance were likely due to disabling chronic disease.

The Value of Sigmoidoscopy to Detect Colonic Ischaemia After Ruptured Abdominal Aortic Aneurysm Repair. Eur J Vasc Endovasc Surg 2018; 57:229-237.

Abstract
OBJECTIVES Diagnosing colonic ischaemia (CI) after ruptured abdominal aortic aneurysm (RAAA) repair is challenging. This study determined the diagnostic value of sigmoidoscopy in patients suspected of CI after RAAA repair. METHODS This was a retrospective multicentre cohort study. Patients who underwent RAAA repair in three hospitals in Amsterdam, the Netherlands, between 2004 and 2011 (AJAX cohort) were included. Sigmoidoscopies were carried out based on clinical judgment. Endoscopy results were classified as "no ischaemia," "mild CI," or "moderate to severe CI." The surgical diagnosis was classified as "transmural" or "no transmural" CI. The value of sigmoidoscopy was assessed with calculation of positive and negative predictive values (PPV, NPV) with 95% CI for transmural CI. Logistic regression analysis was used to express the association of risk factors with CI as adjusted OR. RESULTS Transmural CI was diagnosed in 23 of 351 patients (6.6%). Thirteen of sixteen patients (81%) who underwent direct laparotomy for high suspicion of CI indeed had transmural CI. Forty-six patients (13%) underwent sigmoidoscopy. The prevalence of transmural CI was 22% (10/46; 95% CI 12-36%) in these patients. The PPV for transmural CI of "moderate to severe CI" on sigmoidoscopy was 73% (8/11; 95% CI 43-90%). The PPV of "mild CI" on sigmoidoscopy was 11% (2/19; 95% CI 2.9-31%). The NPV of "no ischaemia" on sigmoidoscopy was 100% (95% CI 78-100%). Cardiac comorbidity (OR 3.1, 95% CI 1.19-7.97), low first haemoglobin (OR 0.6, 95% CI 0.47-0.87), and high vasopressor administration (OR 9.4, 95% CI 1.99-44.46) were independently associated with CI. CONCLUSIONS Sigmoidoscopy increases the likelihood of correctly identifying the presence or absence of transmural CI, especially in patients with a moderate clinical suspicion for CI after RAAA repair.

Abstract
BACKGROUND To evaluate residual endoleak and thrombus organisation with shear wave imaging (SWI) after endoleak embolisation through an animal study. METHODS This prospective experimental study involved eight dogs with creation of 16 iliac aneurysms and type I endoleak after endovascular aneurysm repair (EVAR). Embolisation agents were injected into the sac to seal endoleak. SWI and colour flow Doppler ultrasound (DUS) were performed at implantation, one week, and one and three months after implantation; for three dogs, SWI and DUS were also performed six months after implantation. Digital subtraction angiography and contrast-enhanced computed tomography were performed at sacrifice. Macroscopic and histopathological analyses were processed to identify regions of interest (ROIs) for endoleak, fresh thrombus, organised thrombus and embolisation agent, where SWI elasticity moduli were compared. RESULTS At sacrifice, nine aneurysms had residual endoleak, while seven were sealed. Ten had a fresh and 15 had an organised thrombus. SWI was able to detect all endoleaks, including two cases undetected with DUS. Elasticity moduli of 0.2 kPa ± 0.1 kPa (mean ± SD), 9.5 kPa ± 3.3 kPa, 48.1 kPa ± 21.3 kPa and 44.9 kPa ± 23.7 kPa were found in the ROIs positioned in endoleaks, fresh thrombi, organised thrombi and embolisation agent, respectively. Elasticity values of endoleak and fresh thrombus were lower than those of organised thrombi and embolisation agent (p < 0.001). Stiffness of fresh thrombus at one week (8.7 kPa ± 3.6 kPa) increased at three months (30.2 kPa ± 13.8 kPa), indicating thrombus maturation (p < 0.001). CONCLUSIONS In a dog model of iliac EVAR, SWI was able to identify endoleak, thrombus maturation and embolising agents after endoleak embolisation.

Abstract
BACKGROUND An anatomic severity grade (ASG) score to categorize and to define anatomic factors for abdominal aortic aneurysm (AAA) repair was proposed. Other studies have previously reported that aortic anatomic complexity is a marker of survival and resource utilization after repair, although it remains unclear whether individual components of the ASG score independently contribute to survival. This study analyzed and validated an aortic and iliac artery calcium scoring system that can potentially predict survival after AAA repair. METHODS Patients who underwent infrarenal AAA repairs from July 2007 to May 2012 were analyzed using complete 5-year records. Those who died ≤30 days of surgery were excluded. Calcium score (CS) was defined using the ASG scoring system for its basis by preoperative imaging <6 months before surgery. A CS for any patient was 0 to 5 points, the sum of the points assigned to aortic neck (2 points total) and iliac artery (3 points total) calcification. A receiver operating characteristic curve was used to determine a CS threshold for mortality. The 5-year survivors and deaths were compared in regard to comorbidities, pharmacology, and CS at or above the defined threshold. Each variable with a P value <.1 between the groups was then placed into a Cox proportional hazards model, with statistical significance of P < .05. RESULTS There were 356 patients who underwent AAA repair with complete 5-year follow-up data; 26% died within 5 years of surgery. Of these, 13% had CS of 0 with 15% mortality, 28% had CS of 1 with 21% mortality, 24% had CS of 2 with 24% mortality, 23% had CS of 3 with 35% mortality, 10% had CS of 4 with 40% mortality, and 2% had CS of 5 with 17% mortality. The receiver operating characteristic curve demonstrated an appropriate threshold of CS 3. Of these patients, 65% had a CS <3, whereas 35% had a CS ≥3. Patients with a CS ≥3 had a lower 5-year survival probability (P = .003). Comparing 5-year survivors and deaths in a Cox proportional hazards analysis, CS ≥3 was associated with a hazard ratio of 1.579 (95% confidence interval, 1.038-2.402; P = .0328). CONCLUSIONS A CS ≥3 is linked to a lower 5-year survival after AAA repair in our population. This system potentially can be another measure for risk stratification and serve as a means to predict midterm mortality in AAA repairs. Future study will be needed for further validation to predict midterm mortality and to better guide surgical decision-making.

Abstract
BACKGROUND In endovascular valve and aortic repair, vascular access through a percutaneous approach has become the competing technique to an open surgical approach. The effect on postoperative complications and surgical site infections (SSIs) has been investigated, but randomized evidence is lacking. The objective was to investigate whether percutaneous access of the common femoral artery (CFA) with a percutaneous closure device would decrease the number of SSIs compared with open surgical access of the CFA in endovascular aneurysm repair (EVAR). METHODS Patients with an abdominal aortic aneurysm suitable for EVAR were randomized to open or percutaneous access of the main device (MD) through the CFA. Through the contralateral side, access was obtained with the other technique than the one for which the MD was randomized. The primary outcome was number of SSIs. Secondary outcomes were wound complications, visual analog scale for pain scores, and standardized wound assessment scores during follow-up. Preoperative screening culture and groin biopsy specimens were obtained from all patients. RESULTS Both groups contained 137 groins. SSI rate was 1.5% in the open group vs 0% in the percutaneous group. For MDs only, SSI rate was 3.1% (odds ratio, 3.3; 95% confidence interval, 0.31-347; P = .34). Wound complications were comparable in both groups. Neither nasal nor groin Staphylococcus aureus carriage had a significant effect on SSIs, Southampton Wound Assessment score, or visual analog scale score. Adjusted pain score was 0.69 lower, in favor of percutaneous access. Wound assessment was better after 2 weeks (odds ratio, 3.57; 95% confidence interval, 1.02-12.44; P = .046), also in favor of percutaneous access. CONCLUSIONS Percutaneous access of the CFA does not reduce the number of SSIs. It does, however, reduce pain and improve wound healing with less inflammation 1 day and 2 weeks after EVAR, respectively.

Abstract
BACKGROUND Endovascular aortic aneurysm repair (EVAR) is the preferred first-line treatment for abdominal aortic aneurysms. Current postprocedure surveillance recommendations by manufacturers are a 1-month computed tomography angiography (CTA) followed by a 12-month CTA in most circumstances. The objective of this study is to determine the utility of the 1-month CTA following elective EVAR and determine if initial surveillance at 6-month CTA is appropriate. METHODS A single-center retrospective chart review of all elective EVARs at a tertiary medical center over a 12-year period was conducted. Patients were excluded if postoperative surveillance imaging was not available. Data analysis encompassed demographics, chart review, and imaging including angiogram and cross-sectional imaging to asses for endoleaks and other findings. RESULTS There were 363 patients who underwent elective EVAR and had available postoperative imaging during the study period. Within the 1-month follow-up, a CTA group of 316 patients was detected with 98 (31%) endoleaks. Of these, 5 (1.5%) required intervention: 1 for infolding of an iliac limb and 4 for type I endoleak which was present on completion angiogram-3 in patients treated outside of instructions for use and 1 with a type Ib endoleak on intraoperative completion imaging. In the 158 patients with 1 and 3-month CTAs, there were 47 persistent endoleaks, 9 previously undetected endoleaks not seen in 1-month CTA, and 13 resolved endoleaks. Three patients (1.2%) underwent intervention for type II endoleak and aneurysm expansion. In 47 patients with only a 6-month CTA, there were 16 endoleaks not seen on completion angiography and 2 of which were treated with reintervention-1 for a type I endoleak and 1 for a type II endoleak. CONCLUSIONS There is limited utility to 1-month surveillance CTA in patients undergoing elective EVAR within the device instructions for use that has no evidence of type I endoleak on completion angiography. It is safe to start routine EVAR surveillance at 6 months in this patient population. This has implications when considering bundled and value-based payments in the longitudinal care of abdominal aortic aneurysm patients.

Abstract
PURPOSE: Outcomes of open iliac artery repair (OIR) and endovascular iliac artery repair (EVIR) were compared at a tertiary referral vascular center. METHODS: From 2004 to 2015, all patients treated for isolated iliac artery aneurysms (IAAs) were retrospectively identified, and patient records and computed tomography (CT) scans were analyzed. The primary end point was overall survival; secondary end points were 30-day mortality and morbidity and freedom from reintervention. For follow-up, data from outpatient visits and CT scans following a standard surveillance protocol were used. RESULTS: A total of 106 IAAs in 94 patients were treated (mean follow-up: 35.7 months; 66 OIR; 40 EVIR). Six (15%) aneurysms from the EVIR group and 4 (6.1%) from open-operated IAA presented in the state of rupture. There was no difference in overall survival between EVIR and OIR ( P = .14). In multivariable analysis, higher risk of death was associated with ruptured IAA (rIAA; hazard ratio [HR]: 40.44, 95% confidence interval [CI]: 2.05-796.18; P = .02) and coronary heart disease (HR: 11.07, 95% CI: 1.94-63.36; P < .01). The 30-day mortality was 1.9% overall (0% OIR, 5.0% EVIR, P = .27), but there were no differences between OIR and EVIR in 30-day morbidity ( P = .11). Freedom from reintervention was higher for OIR than for EVIR ( P < .01). In multivariable analysis, a higher reintervention rate was seen in EVIR (HR: 10.80, 95% CI: 2.20-53.01; P < .01) and in rIAA (HR: 12.02, 95% CI: 1.31-111.11; P = .03). CONCLUSION: Iliac artery aneurysmss can be safely and effectively treated by EVIR or OIR regarding 30-day morbidity, mortality, and long-term survival, although freedom from reintervention is significantly lower after EVIR.

Abstract
Patients who have undergone endovascular aneurysm repair (EVAR) need lifelong monitoring because of the risk of aneurysm rupture secondary to delayed endoleaks. Thrombolytic therapy may expose patients with previous EVAR to the risk for development of new endoleaks. We describe a case in which a single dose of intravenous tissue plasminogen activator for acute ischemic stroke was complicated by aneurysm sac expansion secondary to a recurrent endoleak. The potential for a life-threatening complication may warrant routine imaging evaluation of the stent graft after systemic tissue plasminogen activator therapy for acute ischemic stroke in patients with previous EVAR.

Abstract
OBJECTIVES Currently there is no drug therapy for abdominal aortic aneurysm (AAA) and most previous investigations have focused on imaging rather than clinical outcomes. The aim of this study was to assess whether AAA related clinical events were lower in patients prescribed metformin. METHODS This was a prospective cohort observational study performed in three cities in Australia, which was designed to study risk factors for clinical events not simply to focus on metformin. Patients with an asymptomatic unrepaired AAA of any diameter ≥30 mm were recruited from hospital outpatient clinics and surveillance programs run at four centres. The main outcome was the requirement for AAA repair or AAA related mortality (AAA events). The association between metformin prescription and AAA events was assessed using Kaplan-Meier analysis and Cox proportional hazard analysis. RESULTS Patients (1,080) with a mean (SD) initial AAA diameter of 46.1 (11.3) mm were followed for a mean (SD) of 2.5 (3.1) years until an AAA event (n = 454), death (n = 176), loss to follow up (n = 128), or completion of current follow up (n = 322). Patients with diabetes who were prescribed metformin (adjusted HR 0.63, 95% CI 0.44-0.93), but not patients with diabetes who were not prescribed metformin (adjusted HR 1.15, 95% CI 0.83-1.59), had a lower incidence of AAA events compared with those without diabetes. Findings were similar in sensitivity analyses restricted to patients with an initial AAA diameter ≤50 mm and patients with a minimum follow up of six months before an AAA event. CONCLUSIONS These findings suggest that clinically important AAA events may be reduced in patients with diabetes who are prescribed metformin, but not those with diabetes receiving other treatments. A randomised controlled trial is needed to definitively test whether metformin reduces AAA related clinical events in patients with small AAAs who do not have diabetes.

Abstract
OBJECTIVES We report a multicenter experience of urgent late open conversion (LOC), with the goal of identifying the mode of presentation, technical aspects, and outcomes of this cohort of patients. METHODS A retrospective analysis of endovascular aneurysm repair (EVAR) requiring LOC (>30 days after implantation) from 1996 to 2016 in six vascular centers was performed. Patients with aneurysm rupture or other conditions requiring urgent surgery (<24 hours) were included. Patient demographics, time interval between EVAR and LOC, endograft characteristics, previous attempts at endovascular correction, indications, operative technique, 30-day mortality and morbidity, and long-term survival were analyzed. RESULTS There were 42 patients (88.1% men; mean age, 75.8 ± 9.0 years) included. Among the 42 explanted grafts, 33 were bifurcated, 1 tube, 6 aortouni-iliac, and 2 side-branch devices. Suprarenal fixation was present in 78.6%. Twelve patients (28.6%) underwent endovascular reintervention before LOC. Indications for urgent LOC were aneurysm rupture in 24 of the 42 cases (57.1%), endograft infection in 11 (26.2%), endoleak associated with aneurysm growth and pain in 6 (14.3%), and recurrent endograft thrombosis in 2 (4.8%). The proximal aortic cross-clamping site was infrarenal in 38.1% of cases, suprarenal in 19.1%, and supraceliac in 42.9%. Complete removal of the endograft was performed in 32 patients (76.2%) and partial removal in 10 (proximal preservation in 7 of 10). Reconstructions were performed with Dacron grafts in 33 of the 42 cases, cryopreserved arterial allografts in 5, and endograft removal associated with prosthetic axillobifemoral bypass in 4. The 30-day mortality was 23.8%; hemorrhagic shock was an independent risk factor of early mortality (odds ratio, 10.5; 95% confidence interval, 1.5-73.7; P = .018). During a mean follow-up of 23.9 ± 36.0 months, two late aneurysm-related deaths occurred. The estimated 1- and 5-year survival rates were 62.1% and 46.1%, respectively. CONCLUSIONS Urgent LOC after EVAR are associated with high postoperative mortality rates and poor long-term survival. Further studies are necessary to define the timing and the best treatment option for failing EVAR.

Abstract
INTRODUCTION Endovascular aortic repair (EVAR) has improved over the last two decades. Approximately 80% of the patients presenting with an abdominal aortic aneurysm (AAA) is nowadays primarily treated with EVAR. AREAS COVERED In this review, the differences between endovascular and open repair, the clinical characteristics needed for EVAR, the role of clinical imaging and the developments in EVAR technology will be discussed. Early mortality is lower in EVAR as compared to open repair, whereas this benefit is lost after 3 years postoperatively. EVAR comes with a high reintervention rate, with endoleak being the most important predictive factor for reintervention. Expanding technical possibilities have allowed surgeons to choose from a palate of endovascular approaches in aneurysm patients with challenging anatomies. EXPERT COMMENTARY Although EVAR has taken a giant leap forward in development, the new developments have seemed to surpass the long-term limitations with older devices. It is important to start focusing on the current limitations of EVAR, in particular the durability of devices in the human variable anatomic and dynamic environment.

Abstract
PURPOSE OF REVIEW This review discusses the benefits of a completely percutaneous approach to endovascular aortic aneurysm repair (EVAR), and provides an outline as to how this is performed by a multidisciplinary team of cardiologists and cardiovascular surgeons at a quaternary care community hospital. RECENT FINDINGS Percutaneous endovascular aortic aneurysm repair (PEVAR) as compared to EVAR utilizing surgical femoral artery exposure is associated with a significant reduction in operation time, length of stay, access site complications, patient discomfort, and procedural cost. Furthermore, PEVAR may be the preferred approach in patients presenting with aneurysm rupture, as the avoidance of general anesthesia has been associated with improved 30-day mortality. Assuming no contraindication based on vascular anatomy, clinical status, or patient preference, these findings suggest that in properly selected patients, PEVAR should be the primary method for abdominal aortic aneurysm repair in both stable and unstable patients.

Abstract
BACKGROUND The detection of intraprosthetic thrombus (IPT) deposits is a common finding during follow-up for endovascular abdominal aneurysm repair (EVAR); however, its clinical significance is still debated. The aim of this study was to determine if IPT represents a risk factor for thromboembolic events (TEs; endograft or limb thrombosis, or distal embolization) after EVAR. METHODS A systematic review of English literature was undertaken until November 2017. Studies providing 2-group comparison (patients with IPT development on postoperative computed tomography angiography versus patients without IPT) with extractable outcome data (TE related to IPT and/or risk factors for IPT development) were included. Meta-analysis was performed when comparative data were given in 2 or more articles. RESULTS Five single-center studies (808 patients) were analyzed. IPT detection at any time during follow-up occurred in 20.8% (168/808) of patients. Extractable data for postoperative TE were available in 4 studies (613 patients): on comparative meta-analysis, IPT was not significantly associated with TE occurrence during follow-up (odds ratio 2.25, 95% confidence interval [CI] 0.50-10.1; P = 0.29). IPT is generally detected during the first year after EVAR (maximum reported median: 12 months, range: 1.2-23). Polyester graft material (odds ratio 2.34, 95% CI 1.53-3.58; P < 0.001) and aorto-uni-iliac configuration of the endograft (odds ratio 3.27, 95% CI 1.66-6.44; P = 0.001) were confirmed as risk factors for IPT formation on meta-analysis. The literature systematic review suggests that IPT formation may be also associated with long main bodies and large necks. CONCLUSIONS IPT detection on postoperative computed tomography angiography was not significantly associated with the occurrence of TE over time. The aorto-uni-iliac configuration and the use of polyester fabric for endografts were confirmed as risk factors for IPT development.

Although follow-up after open surgical and endovascular procedures is generally regarded as an important part of the care provided by vascular surgeons, there are no detailed or comprehensive guidelines that specify the optimal approaches with regard to testing methods, indications for reintervention, and follow-up intervals. To provide guidance to the vascular surgeon, the Clinical Practice Council of the Society for Vascular Surgery appointed an expert panel and a methodologist to review the current clinical evidence and to develop recommendations for follow-up after vascular surgery procedures. For those procedures for which high-quality evidence was not available, recommendations were based on observational studies, committee consensus, and indirect evidence. Recognizing that there are numerous published reports on the role of duplex ultrasound for surveillance of infrainguinal vein bypass grafts, the Society commissioned a systematic review and meta-analysis on this topic. The panel classified the strength of each recommendation and the corresponding quality of evidence on the basis of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system: recommendations were graded either strong or weak, and the quality of evidence was graded high, moderate, or low. The resulting recommendations represent a wide variety of open surgical and endovascular procedures involving the extracranial carotid artery, thoracic and abdominal aorta, mesenteric and renal arteries, and lower extremity arterial revascularization. The panel also identified many areas in which there was a lack of high-quality evidence to support their recommendations. This suggests that there are opportunities for further clinical research on testing methods, threshold criteria, and the role of surveillance as well as on the modes of failure and indications for reintervention after vascular surgery procedures.

Abstract
Several observational studies and randomized trials have compared open surgery (OS) and endovascular aortic repair (EVAR) for ruptured abdominal aortic aneurysm (rAAA). However, none of these studies addressed optimal management of hemodynamically (hd) unstable patients. Our objective was to compare perioperative outcomes in patients undergoing OS vs EVAR for hd-stable and hd-unstable rAAAs.This retrospective study was conducted in West China Hospital from January 2005 to December 2015. Unstable patients were defined as those who have at least 1 of the following: preoperative shock, preoperative transfusion >4 units, preoperative intubation, cardiac arrest, or unconsciousness. Univariable and multivariable logistic regression analyses were performed.Of the 102 patients, 70.6% underwent OS and 29.4% EVAR. About 46.1% were unstable, and for these patients, OS was performed in 70.2% and EVAR in 29.8%. The 30-day mortality was 23.6% (OS, 25.6%; EVAR, 18.8%; P = .585) for hd-stable patients and was 42.6% (OS, 45.5%; EVAR, 35.7%; P = .537) for hd-unstable patients. Patients with OS had longer operative time and more transfusion. Amongst hd-stable patients, OS subgroup had a higher rate of pneumonia (33.3% vs 6.3%, P = .045), longer intensive care unit (ICU) stay (43.2 vs 15.2 hours, P = .02), and length of stay (11.6 vs 8.6 days, P = .041). Among hd-unstable patients, OS subgroup had a longer ICU stay (134.3 vs 63.8 hours, P = .047). Hospitalization costs of OS group were significantly lower than those of EVAR group, regardless of hemodynamic stability.Approximately one-third of patients with rAAA were treated by EVAR at our institution. EVAR may be the preferred approach for anatomically suitable rAAAs. However, patients treated by EVAR had a similar mortality compared with those treated by OS. In addition, OS is not an independent factor for a higher 30-day mortality, and the costs of OS were much cheaper than those of EVAR. Therefore, OS is difficult to replace, especially in developing countries.

Abstract
BACKGROUND Abdominal aortic aneurysm (AAA) is three to five times more common among men compared with women, yet up to 38% of all aneurysm related deaths affect women. The aim of this study was to estimate the prevalence of synchronous or metachronous aneurysms among women with AAA, as diagnosis and treatment could improve survival. PATIENTS AND METHODS This is a retrospective study of prospectively registered patients. All women operated on, or under surveillance for, AAA were identified at two Swedish hospitals. Aneurysms in different locations were identified using available imaging studies. Aneurysms were defined according to location: thoracic ascending aorta ≥42 mm, descending ≥33 mm, abdominal aorta ≥30 mm, common iliac artery ≥20 mm or 50% wider than the contralateral artery, common femoral artery ≥12 mm, popliteal artery ≥10 mm. RESULTS A total of 339 women with an AAA were included. The median follow up was 2.8 (range 0-15.7) years. Thirty-one per cent had an aneurysm in the thoracic aorta (67 of 217 investigated, 84% were located in the descending aorta), 13 (19%) underwent repair. Twelve per cent had a common iliac artery aneurysm (24/259, 76% were investigated). Common femoral artery aneurysms were identified in 4.3% (8/184, 54% investigated). Popliteal artery aneurysms were identified in 4.0% (6/149, 44% investigated). The prevalence of infrainguinal aneurysms was higher among patients with synchronous iliac aneurysms (40% vs. 1.6%, OR 42, 95% CI 6.4-279, p < .001). CONCLUSIONS Thoracic aortic aneurysms are common among women with AAA, most commonly affecting the descending aorta, and detection frequently results in repair. Popliteal and femoral aneurysms are not rare among women with AAA, and even common if there is a synchronous iliac aneurysm.

Abstract
BACKGROUND An abdominal aortic aneurysm (AAA) is the pathological enlargement of the aorta and can develop in both men and women. Progressive aneurysm enlargement can lead to rupture. The rupture of an AAA is frequently fatal and accounts for the death from haemorrhagic shock of at least 45 people per 100,000 population. The outcome of people with ruptured AAA varies among countries and healthcare systems, with mortality ranging from 53% to 90%. Definitive treatment for ruptured AAA includes open surgery or endovascular repair. The management of haemorrhagic shock is crucial for the person's outcome and aims to restore organ perfusion and systolic blood pressure above 100 mmHg through immediate and aggressive fluid replacement. This rapid fluid replacement is known as the normotensive resuscitation strategy. However, evidence suggests that infusing large volumes of cold fluid causes dilutional and hypothermic coagulopathy. The association of these factors may exacerbate bleeding, resulting in a 'lethal triad' of hypothermia, acidaemia, and coagulopathy. An alternative to the normotensive resuscitation strategy is the controlled (permissive) hypotension resuscitation strategy, with a target systolic blood pressure of 50 mmHg to 100 mmHg. The principle of controlled or hypotensive resuscitation has been used in some management protocols for endovascular repair of ruptured AAA. It may be beneficial in preventing blood loss by avoiding the clot disruption caused by the rapid increase in systolic blood pressure; avoiding dilution of clotting factors, platelets and fibrinogen; and by avoiding the temperature decrease that inhibits enzyme activity involved in platelet and clotting factor function. This is an update of a review first published in 2016. OBJECTIVES To compare the effects of controlled (permissive) hypotension resuscitation and normotensive resuscitation strategies for people with ruptured AAA. SEARCH METHODS The Cochrane Vascular Information Specialist searched the Specialised Register (August 2017), the Cochrane Register of Studies (CENTRAL (2017, Issue 7)) and EMBASE (August 2017). The Cochrane Vascular Information Specialist also searched clinical trials databases (August 2017) for details of ongoing or unpublished studies. SELECTION CRITERIA We sought all published and unpublished randomised controlled trial (RCTs) that compared controlled hypotension and normotensive resuscitation strategies for the management of shock in patients with ruptured abdominal aortic aneurysms. DATA COLLECTION AND ANALYSIS Two review authors independently assessed identified studies for potential inclusion in the review. We used standard methodological procedures in accordance with the Cochrane Handbook for Systematic Review of Interventions. MAIN RESULTS We identified no RCTs that met the inclusion criteria. AUTHORS' CONCLUSIONS We found no RCTs that compared controlled hypotension and normotensive resuscitation strategies in the management of haemorrhagic shock in patients with ruptured abdominal aortic aneurysm that assessed mortality, presence of coagulopathy, intensive care unit length of stay, and the presence of myocardial infarct and renal failure. High quality studies that evaluate the best strategy for managing haemorrhagic shock in ruptured abdominal aortic aneurysms are required.

Abstract
In last 30 years, the endovascular aneurysm repair (EVAR) has become the standard method of treatment of abdominal aortic aneurysms (AAAs). Nevertheless, the method has limitations mainly based on the anatomic characteristics of the specific aneurysm. In these cases, a combination of endovascular and open techniques can be used. We describe a case of a patient with an infrarenal AAA and an ectopic right renal artery emerging from within the aneurysm sac. The patient was treated with a combination of endovascular and open techniques. In particular, he underwent a hepatorenal revascularization followed by a standard EVAR procedure, with a successful final outcome. For the treatment of AAA disease, the combination of open and endovascular procedures can overcome difficulties, where a standard EVAR cannot be an option.

Abstract
Endovascular aneurysm repair (EVAR) has disseminated rapidly as an alternative to open surgical repair for the treatment of abdominal aortic aneurysms (AAAs), because of its reduced invasiveness, low mortality and morbidity rate. The effectiveness of the endovascular devices used in EVAR is always at question as postoperative adverse events can lead to re-intervention or to a possible fatal scenario for the circulatory system. Motivated by the assessment of the risks related to thrombus formation, here the impact of two different commercial endovascular grafts on local hemodynamics is explored through 20 image-based computational hemodynamic models of EVAR-treated patients (N=10 per each endograft model). Hemodynamic features, susceptible to promote thrombus formation, such as flow separation and recirculation, are quantitatively assessed and compared with the local hemodynamics established in image-based infrarenal abdominal aortic models of healthy subjects (N=10). The hemodynamic analysis is complemented by a geometrical characterization of the EVAR-induced reshaping of the infrarenal abdominal aortic vascular region. The findings of this study indicate that: (1) the clinically observed propensity to thrombus formation in devices used in EVAR strategies can be explained in terms of local hemodynamics by means of image-based computational hemodynamics approach; (2) reportedly pro-thrombotic hemodynamic structures are strongly correlated with the geometry of the aortoiliac tract postoperatively. In perspective, our study suggests that future clinical follow up studies could include a geometric analysis of the region of the implant, monitoring shape variations that can lead to hemodynamic disturbances of clinical significance.

Abstract
The technologies and innovations applicable to endovascular treatment for complex aortic pathologies have progressed rapidly over the last two decades. Although the initial outcomes of an endovascular aortic repair have been excellent, as long-term data became available, complications including endoleaks, endograft migration, and endograft infection have become apparent and are of concern. Previously, the indication for endovascular therapy was restricted to descending thoracic aortic aneurysms and abdominal aortic aneurysms. However, its indication has expanded along with the improvement of techniques and devices, and currently, it has become possible to treat pararenal aortic aneurysms and Crawford type 4 thoracoabdominal aortic aneurysm (TAAA) using the off-the-shelf devices. Additionally, custom-made devices allow for the treatment of arch or more extensive TAAAs. Endovascular treatment is applied not only to aneurysms but also to acute/chronic dissections. However, long-term outcomes are still unclear. This article provides an overview of available devices and the results of endovascular treatment for various aortic pathologies.

Abstract
Antithrombotic treatment including anticoagulants and antiplatelets has evolved during the last decades, and several recommendations have been included in the latest guidelines regarding the proper management of patients undergoing vascular surgery. However, there are significant differences compared to older recommendations, and indications vary among patients with peripheral artery disease, carotid disease, and abdominal aortic aneurysm. In this mini review, we critically evaluate all these data to produce useful conclusions for everyday clinical practice.
