RESUMO
As a progressive disease process, early diagnosis and ongoing monitoring and treatment of lower limb peripheral artery disease (PAD) is critical to reduce the risk of diabetes-related foot ulcer (DFU) development, non-healing of wounds, infection and amputation, in addition to cardiovascular complications. There are a variety of non-invasive tests available to diagnose PAD at the bedside, but there is no consensus as to the most diagnostically accurate of these bedside investigations or their reliability for use as a method of ongoing monitoring. Therefore, the aim of this systematic review was to first determine the diagnostic accuracy of non-invasive bedside tests for identifying PAD compared to an imaging reference test and second to determine the intra- and inter-rater reliability of non-invasive bedside tests in adults with diabetes. A database search of Medline and Embase was conducted from 1980 to 30 November 2022. Prospective and retrospective investigations of the diagnostic accuracy of bedside testing in people with diabetes using an imaging reference standard and reliability studies of bedside testing techniques conducted in people with diabetes were eligible. Included studies of diagnostic accuracy were required to report adequate data to calculate the positive likelihood ratio (PLR) and negative likelihood ratio (NLR) which were the primary endpoints. The quality appraisal was conducted using the Quality Assessment of Diagnostic Accuracy Studies and Quality Appraisal of Reliability quality appraisal tools. From a total of 8517 abstracts retrieved, 40 studies met the inclusion criteria for the diagnostic accuracy component of the review and seven studies met the inclusion criteria for the reliability component of the review. Most studies investigated the diagnostic accuracy of ankle -brachial index (ABI) (N = 38). In people with and without DFU, PLRs ranged from 1.69 to 19.9 and NLRs from 0.29 to 0.84 indicating an ABI <0.9 increases the likelihood of disease (but the extent of the increase ranges from a small to large amount) and an ABI within the normal range (≥0.90 and <1.3) does not exclude PAD. For toe-brachial index (TBI), a threshold of <0.70 has a moderate ability to rule PAD in and out; however, this is based on limited evidence. Similarly, a small number of studies indicate that one or more monophasic Doppler waveforms in the pedal arteries is associated with the presence of PAD, whereas tri- or biphasic waveform suggests that PAD is less likely. Several forms of bedside testing may also be useful as adjunct tests and 7 studies were identified that investigated the reliability of bedside tests including ABI, toe pressure, TBI, transcutaneous oxygen pressure (TcPO2 ) and pulse palpation. Inter-rater reliability was poor for pulse palpation and moderate for TcPO2. The ABI, toe pressure and TBI may have good inter- and intra-rater reliability, but margins of error are wide, requiring a large change in the measurement for it to be considered a true change rather than error. There is currently no single bedside test or a combination of bedside tests that has been shown to have superior diagnostic accuracy for PAD in people with diabetes with or without DFU. However, an ABI <0.9 or >1.3, TBI of <0.70, and absent or monophasic pedal Doppler waveforms are useful to identify the presence of disease. The ability of the tests to exclude disease is variable and although reliability may be acceptable, evidence of error in the measurements means test results that are within normal limits should be considered with caution and in the context of other vascular assessment findings (e.g., pedal pulse palpation and clinical signs) and progress of DFU healing.

Diabetes related foot complications have become a major cause of morbidity and are implicated in most major and minor amputations globally. Approximately 50% of people with diabetes and a foot ulcer have peripheral artery disease (PAD) and the presence of PAD significantly increases the risk of adverse limb and cardiovascular events. The International Working Group on the Diabetic Foot (IWGDF) has published evidence based guidelines on the management and prevention of diabetes related foot complications since 1999. This guideline is an update of the 2019 IWGDF guideline on the diagnosis, prognosis and management of peripheral artery disease in people with diabetes mellitus and a foot ulcer. For this guideline the IWGDF, the European Society for Vascular Surgery and the Society for Vascular Surgery decided to collaborate to develop a consistent suite of recommendations relevant to clinicians in all countries. This guideline is based on three new systematic reviews. Using the Grading of Recommendations, Assessment, Development, and Evaluation framework clinically relevant questions were formulated, and the literature was systematically reviewed. After assessing the certainty of the evidence, recommendations were formulated which were weighed against the balance of benefits and harms, patient values, feasibility, acceptability, equity, resources required, and when available, costs. Through this process five recommendations were developed for diagnosing PAD in a person with diabetes, with and without a foot ulcer or gangrene. Five recommendations were developed for prognosis relating to estimating likelihood of healing and amputation outcomes in a person with diabetes and a foot ulcer or gangrene. Fifteen recommendations were developed related to PAD treatment encompassing prioritisation of people for revascularisation, the choice of a procedure and post-surgical care. In addition, the Writing Committee has highlighted key research questions where current evidence is lacking. The Writing Committee believes that following these recommendations will help healthcare professionals to provide better care and will reduce the burden of diabetes related foot complications.

INTRODUCTION: Peripheral artery disease (PAD) is associated with an increased likelihood of delayed or non-healing of a diabetes-related foot ulcer, gangrene, and amputation. The selection of the most effective surgical technique for revascularisation of the lower limb in this population is challenging and there is a lack of conclusive evidence to support the choice of intervention. This systematic review aimed to determine, in people with diabetes and tissue loss, if direct revascularisation is superior to indirect revascularisation and if endovascular revascularisation is superior to open revascularisation for the outcomes of wound healing, minor or major amputation, and adverse events including mortality. METHODS: Title and abstract searches of Medline, Embase, PubMed, and EBSCO were conducted from 1980 to 30th November 2022. Cohort and case-control studies and randomised controlled trials reporting comparative outcomes of direct (angiosome) revascularisation (DR) and indirect revascularisation (IR) or the comparative outcomes of endovascular revascularisation and open or hybrid revascularisation for the outcomes of healing, minor amputation, and major amputation in people with diabetes, PAD and tissue loss (including foot ulcer and/or gangrene) were eligible. Methodological quality was assessed using the Cochrane risk-of-bias tool for randomised trials, the ROBINS-I tool for non-randomised studies, and Newcastle-Ottawa Scale for observational and cohort studies where details regarding the allocation to intervention groups were not provided. RESULTS: From a total 7086 abstracts retrieved, 26 studies met the inclusion criteria for the comparison of direct angiosome revascularisation (DR) and indirect revascularisation (IR), and 11 studies met the inclusion criteria for the comparison of endovascular and open revascularisation. One study was included in both comparisons. Of the included studies, 35 were observational (31 retrospective and 4 prospective cohorts) and 1 was a randomised controlled trial. Cohort study quality was variable and generally low, with common sources of bias related to heterogeneous participant populations and interventions and lack of reporting of or adjusting for confounding factors. The randomised controlled trial had a low risk of bias. For studies of DR and IR, results were variable, and it is uncertain if one technique is superior to the other for healing, prevention of minor or major amputation, or mortality. However, the majority of studies reported that a greater proportion of participants receiving DR healed compared with IR, and that IR with collaterals may have similar outcomes to DR for wound healing. For patients with diabetes, infrainguinal PAD, and an adequate great saphenous vein available for use as a bypass conduit who were deemed suitable for either surgical procedure, an open revascularisation first approach was superior to endovascular therapy to prevent a major adverse limb event or death (Hazard Ratio: 0.72; 95% CI 0.61-0.86). For other studies of open and endovascular approaches, there was generally no difference in outcomes between the interventions. CONCLUSIONS: The majority of available evidence for the effectiveness of DR and IR and open and endovascular revascularisation for wound healing and prevention of minor and major amputation and adverse events including mortality in people with diabetes, PAD and tissue loss is inconclusive, and the certainty of evidence is very low. Data from one high quality randomised controlled trial supports the use of open over endovascular revascularisation to prevent a major limb event and death in people with diabetes, infrainguinal disease and tissue loss who have an adequate great saphenous vein available and who are deemed suitable for either approach.

INTRODUCTION: The presence of peripheral artery disease (PAD) confers a significantly increased risk of failure to heal and major lower limb amputation for people with diabetes-related foot ulcer (DFU). Determining performance of non-invasive bedside tests for predicting likely DFU outcomes is therefore key to effective risk stratification of patients with DFU and PAD to guide management decisions. The aim of this systematic review was to determine the performance of non-invasive bedside tests for PAD to predict DFU healing, healing post-minor amputation, or need for minor or major amputation in people with diabetes and DFU or gangrene. METHODS: A database search of Medline and Embase was conducted from 1980 to 30 November 2022. Prospective studies that evaluated non-invasive bedside tests in patients with diabetes, with and without PAD and foot ulceration or gangrene to predict the outcomes of DFU healing, minor amputation, and major amputation with or without revascularisation, were eligible. Included studies were required to have a minimum 6-month follow-up period and report adequate data to calculate the positive likelihood ratio (PLR) and negative likelihood ratio for the outcomes of DFU healing, and minor and major amputation. Methodological quality was assessed using the Quality in Prognosis Studies tool. RESULTS: From 14,820 abstracts screened 28 prognostic studies met the inclusion criteria. The prognostic tests evaluated by the studies included: ankle-brachial index (ABI) in 9 studies; ankle pressures in 10 studies, toe-brachial index in 4 studies, toe pressure in 9 studies, transcutaneous oxygen pressure (TcPO2 ) in 7 studies, skin perfusion pressure in 5 studies, continuous wave Doppler (pedal waveforms) in 2 studies, pedal pulses in 3 studies, and ankle peak systolic velocity in 1 study. Study quality was variable. Common reasons for studies having a moderate or high risk of bias were poorly described study participation, attrition rates, and inadequate adjustment for confounders. In people with DFU, toe pressure ≥30 mmHg, TcPO2 ≥25 mmHg, and skin perfusion pressure of ≥40 mmHg were associated with a moderate to large increase in pretest probability of healing in people with DFU. Toe pressure ≥30 mmHg was associated with a moderate increase in healing post-minor amputation. An ABI using a threshold of ≥0.9 did not increase the pretest probability of DFU healing, whereas an ABI <0.5 was associated with a moderate increase in pretest probability of non-healing. Few studies investigated amputation outcomes. An ABI <0.4 demonstrated the largest increase in pretest probability of a major amputation (PLR ≥10). CONCLUSIONS: Prognostic capacity of bedside testing for DFU healing and amputation is variable. A toe pressure ≥30 mmHg, TcPO2 ≥25 mmHg, and skin perfusion pressure of ≥40 mmHg are associated with a moderate to large increase in pretest probability of healing in people with DFU. There are little data available evaluating the prognostic capacity of bedside testing for healing after minor amputation or for major amputation in people with DFU. Current evidence suggests that an ABI <0.4 may be associated with a large increase in risk of major amputation. The findings of this systematic review need to be interpreted in the context of limitations of available evidence, including varying rates of revascularisation, lack of post-revascularisation bedside testing, and heterogenous subpopulations.

BACKGROUND: No evaluation of the quality of different carotid guidelines using validated scales has been performed to date. The present study aims to analyze 3 carotid stenosis guidelines, apprizing their quality and reporting using validated tools. METHODS: A survey-based assessment of the quality of the European Society for Vascular Surgery (ESVS) 2023, European Stroke Organisation (ESO) 2021, and the Society for Vascular Surgery (SVS) 2021 carotid stenosis guidelines, was performed by 43 vascular surgeons, cardiologists, neurologist or interventional radiologists using 2 validated appraisal tools for quality and reporting guidelines, the AGREE II instrument and the RIGHT statement. RESULTS: Using the AGREE II tool, the ESVS, SVS, and ESO guidelines had overall quality scores of 87.3%, 79.4%, and 82.9%, respectively (P = 0.001) The ESVS and ESO had better scores in the scope and purpose domain, and the SVS in the clarity of presentation domain. In the RIGHT statement, the ESVS, SVS, and ESO guidelines had overall quality scores of 84.0.7%, 74.3%, and 79.0%, respectively (P = 0.001). All 3 guidelines stood out for their methodology for search of evidence and formulating evidence-based recommendations. On the contrary, were negatively evaluated mostly in the cost and resource implications in formulating the recommendations. CONCLUSIONS: The 2023 ESVS carotid stenosis guideline was the best evaluated among the 3 guidelines, with scores over 5% higher than the other 2 guidelines. Efforts should be made by guideline writing committees to take the AGREE II and RIGHT statements into account in the development of future guidelines to produce high-quality recommendations.

RESUMO
OBJECTIVE: This cohort study aimed to prospectively determine the impact of multidisciplinary team meetings (MDTs) on treatment plans in vascular patients. METHODS: The weekly MDT at the institution consisted of a structured discussion of vascular cases in the presence of at least one representative of each specialty from vascular surgery, angiology, and interventional radiology. Participants were asked to examine the cases entered on the digital MDT platform and to fill in forms with a detailed open text treatment recommendation for each patient. Individual recommendations were compared with the final MDT decision, which was based on a shared decision after discussion of clinical and radiological data. The primary endpoint was the agreement rate. The rate of decision implementation was determined to verify the adherence to MDT recommendations. RESULTS: Four hundred consecutive case discussions in 367 patients between November 2019 and March 2021 were included, excluding patients needing urgent treatment, yielding MDT discussion in 88.5% of carotid artery cases, 83% of aorto-iliac cases, and 51.7% of peripheral arterial cases, which included 56.9% of the chronic limb threatening ischaemia cases. The overall average agreement rate was 71% ± 41%. Analysis according to the specialty of the attending physician showed agreement rates of 82% ± 30% for senior vascular surgeons, 62% ± 44% for junior vascular surgeons, 71% ± 43% for interventional radiologists, 58% ± 50% for angiologists (p < .001), and 75% ± 38% considering only senior practitioners. The inter-rater agreement, resulted in kappa coefficients of 0.60 - 0.68 for senior vascular surgeons, 0.29 - 0.31 for junior vascular surgeons, 0.39 - 0.52 for interventional radiologists, and 0.25 for angiologists. The MDT treatment decision was implemented in 353 (96.2%) cases. CONCLUSION: The impact of MDT discussion on treatment recommendations and the adherence to MDT recommendations were significant and in line with results reported from other specialties.

OBJECTIVE: Chronic mesenteric ischaemia (CMI) treatment focuses on symptom relief and prevention of disease progression. Endovascular repair represents the main treatment modality, while data on the associated antiplatelet regimen are scarce. The aim of this meta-analysis was to assess the early and midterm outcomes of endovascular repair in patients with CMI. DATA SOURCES: Randomised controlled trials and observational studies (1990 - 2022) reporting on early and midterm endovascular repair outcomes in patients with atherosclerotic CMI. REVIEW METHODS: The PRISMA guidelines and PICO model were followed. The protocol was registered to PROSPERO (CRD42023401685). Medline, Embase (via Ovid), and Cochrane databases were searched (end date 21 February 2023). The Newcastle-Ottawa Scale was used for risk of bias assessment, and GRADE for evidence quality assessment. Primary outcomes were technical success, 30 day mortality, and symptom relief, assessed using prevalence meta-analysis. The role of dual antiplatelet therapy (DAPT) was investigated using meta-regression analysis. RESULTS: Sixteen retrospective studies (1 224 patients; mean age 69.8 ± 10.6 years; 60.3% female) reporting on 1 368 target vessels (57.8% superior mesenteric arteries) were included. Technical success was 95.0% (95% CI 93 - 97%, p = .28, I2 19%, low certainty), the 30 day mortality rate was 2.0% (95% CI 2 - 4%, p = .93, I2 36%, low certainty), and immediate symptom relief was 87.0% (95% CI 80 - 92%, p < .010, I2 85%, very low certainty). At mean follow up of 28 months, the mortality rate was 15.0% (95% CI 9 - 25%, p = .010, I2 86%, very low certainty), symptom recurrence 25.0% (95% CI 21 - 31%, p < .010, I2 68%, very low certainty) and re-intervention rate 26.0% (95% CI 17 - 37%, p < .010, I2 92%, very low certainty). Single antiplatelet therapy (SAPT) and DAPT performed similarly in the investigated outcomes. CONCLUSION: Endovascular repair for CMI appears to be safe as first line treatment, with a low peri-operative mortality rate and acceptable immediate symptom relief. During midterm follow up, symptom recurrence and need for re-intervention are not uncommon. SAPT appears to be equal to DAPT in post-operative outcomes.

RESUMO
OBJECTIVE: There is no consensus regarding the terminology, definition, classification, diagnostic criteria, and algorithm, or reporting standards for the disease of infective native aortic aneurysm (INAA), previously known as mycotic aneurysm. The aim of this study was to establish this by performing a consensus study. METHODS: The Delphi methodology was used. Thirty-seven international experts were invited via mail to participate. Four two week Delphi rounds were performed, using an online questionnaire, initially with 22 statements and nine reporting items. The panellists rated the statements on a five point Likert scale. Comments on statements were analysed, statements revised, and results presented in iterative rounds. Consensus was defined as ≥ 75% of the panel selecting "strongly agree" or "agree" on the Likert scale, and consensus on the final assessment was defined as Cronbach's alpha coefficient > .80. RESULTS: All 38 panellists completed all four rounds, resulting in 100% participation and agreement that this study was necessary, and the term INAA was agreed to be optimal. Three more statements were added based on the results and comments of the panel, resulting in a final 25 statements and nine reporting items. All 25 statements reached an agreement of ≥ 87%, and all nine reporting items reached an agreement of 100%. The Cronbach's alpha increased for each consecutive round (round 1 = .84, round 2 = .87, round 3 = .90, and round 4 = .92). Thus, consensus was reached for all statements and reporting items. CONCLUSION: This Delphi study established the first consensus document on INAA regarding terminology, definition, classification, diagnostic criteria, and algorithm, as well as reporting standards. The results of this study create essential conditions for scientific research on this disease. The presented consensus will need future amendments in accordance with newly acquired knowledge.
RESUMO
BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has become a standard treatment for acute and chronic thoracic aorta diseases. We analyzed long-term outcomes and risk factors of TEVAR procedures according to the aortic pathology. METHODS: Demographics, indications, technical details, and outcomes of patients undergoing TEVAR procedures in our institutions were prospectively collected and retrospectively analyzed. Overall survival was determined using Kaplan-Meier methods while log-rank tests were used to compare the survival between groups. Cox regression analysis was used to identify risk factors. RESULTS: Between June 2002 and April 2020, 116 patients underwent TEVAR for different thoracic aorta diseases. Among them, 47 patients (41%) underwent TEVAR for aneurysmatic aortic disease, 26 (22%) for type-B aortic dissection, 23 (20%) for penetrating aortic ulcer, 11 (9%) after previous type-A dissection treatment, and 9 (8%) for traumatic aortic injury. Patients with posttraumatic aortic injury were younger (P < 0.01) with less hypertension (P < 0.01), diabetes (P < 0.01), and prior cardiac surgery (P < 0.01). Survival was different based on indication for TEVAR (log rank 0.024). Patients after previous type-A dissection treatment had the worst survival rate (50% at 5 years) while survival for aneurysmatic aortic disease was 55% at 5 years. No late death occurred in the traumatic group. Cox-regression model identified independent predictors for mortality: age (hazard ratio [HR]: 1.05, 95% confidence interval [CI]: 1.01-1.09, P = 0.006), male gender (HR: 3.2, 95% CI: 1.1-9.2, P = 0.028), moderate chronic obstructive pulmonary disease (HR: 2.1, 95% CI: 1.02-4.55, P = 0.043), previous cardiac surgery (HR: 2.1, 95% CI: 1.008-4.5, P = 0.048), and treatment indication for aneurysm (HR: 2.6, 95% CI: 1.2-5.2, P = 0.008). CONCLUSIONS: TEVAR is a safe and effective procedure with excellent long-term results in case of traumatic aortic injury. The overall long-term survival is affected by aortic pathology, associated comorbidities, gender, and previous cardiac surgery.

OBJECTIVE: To perform a scoping review of how patients with COVID-19 are affected by acute limb ischaemia (ALI) and evaluate the recommendations of the 2020 ESVS ALI Guidelines for these patients. METHODS: Research questions were defined, and a systematic literature search was performed following the PRISMA guidelines. Abstracts and unpublished literature were not included. The definition of ALI in this review is in accordance with the ESVS guidelines. RESULTS: Most identified papers were case reports or case series, although population based data and data from randomised controlled trials were also identified. In total, 114 unique and relevant papers were retrieved. Data were conflicting concerning whether the incidence of ALI increased, or remained unchanged, during the pandemic. Case reports and series reported ALI in patients who were younger and healthier than usual, with a greater proportion affecting the upper limb. Whether or not this is coincidental remains uncertain. The proportion of men/women affected seems unchanged. Most reported cases were in hospitalised patients with severe COVID-19. Patients with ALI as their first manifestation of COVID-19 were reported. Patients with ALI have a worse outcome if they have a simultaneous COVID-19 infection. High levels of D-dimer may predict the occurrence of arterial thromboembolic events in patients with COVID-19. Heparin resistance was observed. Anticoagulation should be given to hospitalised COVID-19 patients in prophylactic dosage. Most of the treatment recommendations from the ESVS Guidelines remained relevant, but the following were modified regarding patients with COVID-19 and ALI: 1) CTA imaging before revascularisation should include the entire aorta and iliac arteries; 2) there should be a high index of suspicion, early testing for COVID-19 infection and protective measures are advised; and 3) there should be preferential use of local or locoregional anaesthesia during revascularisation. CONCLUSION: Although the epidemiology of ALI has changed during the pandemic, the recommendations of the ESVS ALI Guidelines remain valid. The above mentioned minor modifications should be considered in patients with COVID-19 and ALI.

Over the last years, the endovascular approach to the management of the acute and chronic deep vein thrombosis (DVT) has gained more and more attention from the scientific community. DVT is the third most common cardiovascular disease after coronary heart disease and stroke, with classic treatment based on anticoagulation. Recent evidences have highlighted the risk of postthrombotic syndrome as high as 30%-50% in proximal ilio-femoral lesions, with irreversible clinical symptoms and impact on the quality of life of the population. Since 2000s, the new concept of thrombus removal in the acute phase has been supported by the introduction of different techniques based on the endovascular ablation of the clot by in-situ fibrinolysis and, more recently, fragmentation and aspiration. In the chronic phase, recanalization of the thrombosed segment is recommended by stent placement to remove the obstruction and eventually reduce the congestion. Immediate technical success of these procedures is widely satisfying, whereas the long-term clinical benefits are still debated. This paper presents an overview of the modern management of the DVT by endovascular approach with regard to the clinical contexts, interventional strategies and clinical outcomes. Endovascular specialist needs to be aware of this incoming challenge, as local expertise is demanded for the modern management of these patients in multidisciplinary theaters.

Despite recent guideline updates on peripheral artery disease (PAD) and critical limb ischemia (CLI) treatment, the optimal treatment for CLI is still being debated. As a result, care is inconsistent, with many CLI patients undergoing an amputation prior to what many consider to be mandatory: consultation with an interdisciplinary specialty care team and a comprehensive imaging assessment. More importantly, quality imaging is critical in CLI patients with below-the-knee disease. Therefore, the CLI Global Society has put forth an interdisciplinary expert recommendation for superselective digital subtraction angiography (DSA) that includes the ankle and foot in properly indicated CLI patients to optimize limb salvage. A recommended imaging algorithm for CLI patients is included.

OBJECTIVE: Procedural characteristics, including stent design, may influence the outcome of carotid artery stenting (CAS). A thorough comparison of the effect of stent design on outcome of CAS is thus warranted to allow for optimal evidence-based clinical decision making. This study sought to evaluate the effect of stent design on clinical and radiologic outcomes of CAS. METHODS: A systematic search was conducted in MEDLINE, Embase, and Cochrane databases in May 2018. Included were articles reporting on the occurrence of clinical short- and intermediate-term major adverse events (MAEs; any stroke or death) or radiologic adverse events (new ischemic lesions on postprocedural magnetic resonance diffusion-weighted imaging [MR-DWI], restenosis, or stent fracture) in different stent designs used to treat carotid artery stenosis. Random effects models were used to calculate combined overall effect sizes. Metaregression was performed to identify the effect of specific stents on MAE rates. RESULTS: From 2654 unique identified articles, two randomized, controlled trials and 66 cohort studies were eligible for analysis (including 46,728 procedures). Short-term clinical MAE rates were similar for patients treated with open cell vs closed cell or hybrid stents. Use of an Acculink stent was associated with a higher risk of short-term MAE compared with a Wallstent (risk ratio [RR], 1.51; P = .03), as was true for use of Precise stent vs Xact stent (RR, 1.55; P < .001). Intermediate-term clinical MAE rates were similar for open vs closed cell stents. Use of open cell stents predisposed to a 25% higher chance (RR, 1.25; P = .03) of developing postprocedural new ischemic lesions on MR-DWI. No differences were observed in the incidence of restenosis, stent fracture, or intraprocedural hemodynamic depression with respect to different stent design. CONCLUSIONS: Stent design is not associated with short- or intermediate-term clinical MAE rates in patients undergoing CAS. Furthermore, the division in open and closed cell stent design might conceal true differences in single stent efficacy. Nevertheless, open cell stenting resulted in a significantly higher number of subclinical postprocedural new ischemic lesions detected on MR-DWI compared with closed cell stenting. An individualized patient data meta-analysis, including future studies with prospective homogenous study design, is required to adequately correct for known risk factors and to provide definite conclusions with respect to carotid stent design for specific subgroups.

BACKGROUND: The postmarket research goal is to assess "generalizability" or "external validity" to see if the early results of clinical trials with investigational devices are reproducible in everyday practice in the real world and the longer term. Registries have an important but ambivalent role in achieving this goal. METHODS: Although registries are common, in practice they follow the regulatory processes that appear designed primarily for pharmaceutical clinical trials and confirmatory studies. We review the literature to assess different definitions and the role of registries in the hierarchy of scientific evidence. We analyze common characteristics affecting registry design, implementation, and governance as well as safety reporting and off-label use while describing the experience of setting up an international, prospective registry for an endovascular device used to treat abdominal aortic aneurysms. RESULTS: Key areas in which to distinguish registries from trials are as follows: eligibility, setting (patients and institutions), device configurations and iterations, the use of design and quality "spaces," a focus on systematic quality checks (rather than source data monitoring), open-ended follow-up, flexibility in the definition of end points and sample sizes, data sharing, and publishing commitments. CONCLUSION: Both clinical trials and registries are essential and complementary research methods and the strengths and weaknesses of each need to be recognized. The specific characteristics of registry research deserve to be acknowledged and safeguarded in the regulations governing clinical investigations with medical devices.

PURPOSE: To prospectively analyze technical and clinical outcome of percutaneous thrombectomy aspiration using a vacuum-assisted thrombectomy catheter in acutely thrombosed dialysis arteriovenous fistula (AVF) and/or arteriovenous graft (AVG). MATERIALS AND METHODS: From June 2016 to April 2017, 35 patients (average age, 61.8 y; range, 33-81 y) presenting with acute thrombosis of dialysis AVF and/or AVG were prospectively evaluated for mechanical thrombectomy using the Indigo System. Adjunctive therapies and procedure-related complications were noted. Technical success, clinical success, primary patency, primary assisted patency, and secondary patency of the dialysis fistula were assessed. RESULTS: Mean follow-up time was 8.5 months (range, 3-12 months). Technical success was 97.1% (34/35 patients). Clinical success was 91.4% (32/35 patients). Complications included hematoma (n = 1), thrombosis < 24 hours (n = 1), and perforation (n = 1). Other mechanical/aspiration thrombectomy devices were used in 1 site to clear the thrombus burden (Arrow-Trerotola [2.8%; 1/35 patients] and Fogarty [5.7%; 2/35 patients]). Average procedure time was 38.1 minutes (range, 15-140 min). Average blood loss during the procedure was 122.5 mL (range, 50-300 mL). The 6-month primary patency, primary assisted patency, and secondary patency were 71%, 80%, and 88.5%. No risk factors for early dialysis fistula occlusion were identified. There was no 30-day mortality. CONCLUSIONS: Percutaneous mechanical thrombectomy aspiration of thrombosed dialysis AVF and/or AVG with a vacuum-assisted thrombectomy catheter is a safe procedure with a low complication rate and effective method for restoring patency before hemodialysis.
