Accordingly, which is the most proper therapeutic conduct in these patients is unknown. International guidelines are elusive in this regard.7,8 Although most physicians end up managing these patients with therapeutic doses of anticoagulants because of the feared risk of progression to the deep vein system, as far as we know there is no evidence of treatment failure coming from the long-term follow-up of patients managed with lower doses. Here we report the findings from an international registry. The Computerized Registry of Patients with Venous Thromboembolism (RIETE) (ClinicalTrials.gov Identifier: NCT02832245) is a large prospective registry that has been enrolling patients with objectively confirmed VTE since 2001.9 The main objective of RIETE is to provide information to help physicians to improve their knowledge on the natural history of thromboembolic disease, including epidemiologic, diagnostic, prophylactic, and therapeutic information. All enrollees provide written or verbal informed consent according to the local ethics protocols of enrolling centers. The institutional review board at each enrolling center approves participation in RIETE for the site investigators and allows the entry of de-identified patient information into the RIETE database. Out of 1320 patients with isolated SVT (i.e., without simultaneous involvement of the deep venous system, as assessed by systematic bilateral ultrasonography) who were enrolled in the RIETE registry between March 2015 and June 2021, 374 (28.3%) had a thrombosis involving the most proximal tract of the greater saphenous with the thrombus head being within 3 cm from the saphenous–femoral junction. Of these patients, 227 (60.7%) were managed with full-dose LMWH or therapeutic doses of fondaparinux overlapped with and/or followed by vitamin K antagonists or direct oral anticoagulants.

Up to 2 million individuals have this condition in the United States, and prevalence is anticipated to grow owing to aging of the population and increase in atherosclerotic risk factors such as diabetes and renal disease.1 In addition to the threat of limb dysfunction and amputation, patients with CLTI are at a high risk of cardioand cerebrovascular morbidity and mortality, with risk that exceeds that of most other cardiovascular patients. Within 1 year, 1 in 5 CLTI patients dies, and an additional one quarter will require major limb amputation.2 Care of the CLTI patient is complex, multifaceted, and multidisciplinary. Medical therapy, wound care, interpretation of noninvasive and invasive vascular testing, and the performance of revascularization procedures are integral to achieve limb salvage. Both surgical and endovascular revascularization have been established as effective treatment modalities that alleviate symptoms and promote healing. Decisions regarding revascularization strategy for individual patients are nuanced and depend in part on comorbidities, anatomy, functional status, conduit availability, presence of suitable bypass target, and other factors. Endovascular revascularization is performed by physicians across a variety of disciplines including vascular surgeons— the only specialty providing both endovascular and open surgical intervention—interventional radiologists, interventional cardiologists, and others.3 Irrespective of specialty, the endovascular specialist focused on CLTI should understand the role of surgical revascularization, understand the likelihood of short-term and long-term success with each type of revascularization, possess competencies that extend beyond catheter-based therapies, and integrate other CLTI SCAI/ACR/APMA/SCVS/SIR/SVM/SVS/VESS Position Statement on Competencies for Endovascular Specialists Providing CLTI Care","PeriodicalId":151049,"journal":{"name":"Vascular Medicine (London, England)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116785284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the impact of habitual sedentary patterns on popliteal artery endothelial health is unclear. We tested the hypothesis that greater habitual total sedentary time, more time spent in prolonged sedentary bouts, and fewer sedentary breaks would be associated with worse popliteal flow-mediated dilation (FMD) responses. Methods: This cross-sectional study used 98 healthy participants (19–77 years, 53 females) that wore an activPAL monitor on the thigh for 6.4 ± 0.8 days to objectively measure sedentary activity and completed a popliteal ultrasound assessment to determine FMD. Both relative (%baseline diameter) and absolute (mm) FMD were calculated. Using bivariate correlation and multiple regression analyses, we examined if there were relationships between sedentary outcomes and FMD while statistically controlling for any potential confounders. Results: In the multiple regression model, age (p = 0.006, β = −0.030, 95% CI = −0.051, −0.009) and total time in sedentary bouts > 1 hour (p = 0.031, β = −0.005, 95% CI = −0.009, −0.001) were independent predictors of relative FMD. Age (β = −0.002, 95% CI = −0.003, −0.001), mean blood flow (β = 0.013, 95% CI = 0.002, 0.024), moderate-intensity physical activity (β = 155.9E−5, 95% CI = 22.4E−5, 289.4E−5), sedentary breaks (β = 0.036, 95% CI = 0.007, 0.066), and total time spent in sedentary bouts > 1 hour (β = −25.02E−5, 95% CI = −47.67E−5, −2.378E−5) were predictors of absolute FMD (all, p < 0.047). All independent outcomes remained significant after partially controlling for all other predictor variables (all, p < 0.031).

Therefore, this pilot study aimed to determine the diagnostic test accuracy of the TBI for PAD following an exercise protocol in participants with suspected PAD. This prospective cross-sectional study ran between 2019 and 2020 in a private vascular laboratory in Newcastle, Australia. Adults exhibiting signs or symptoms consistent with PAD were recruited. Exclusion criteria included inability to adhere to testing protocol (e.g., treadmill walking), conditions preventing toe or brachial pressure measurement (e.g., vasoneural disorders, connective tissue disorders, hallux wound or bilateral mastectomy). Informed written consent was obtained, and ethics approval was in place (H-2010-1230). One limb per participant was included in the study – the symptomatic limb, or where both limbs were symptomatic, the right limb. One vascular sonographer conducted all assessments, with inter-rater reliability previously determined to be acceptable.6 All measurements were taken in a temperature-controlled clinical room (23–25°C). Pretesting participant protocols and the measurement procedure for pressure measurements for the vascular laboratory are consistent with current guidelines and as previously described.1,4 A Hadeco Smartdop 45 (Hadeco, Kawasaki, Japan) with a photoplethysmography probe was used to measure systolic toe pressure (TP). Participants walked on a treadmill at a maximum of 3 km/ hour and a 10° incline for up to 5 minutes. If the participant experienced excessive lower extremity discomfort, angina, or dyspnoea, exercise was ceased. Toe, ankle, and brachial pressures were then immediately recorded in a supine position. Subsequently, visualisation of arteries and peak systolic velocities were obtained from the distal aorta to the foot via colour duplex ultrasound (reference standard) and were completed in the same session. Velocity ratios for grading of stenoses have previously been reported.6 Descriptive statistics and measures of sensitivity, specificity, and positive and negative likelihood ratios with 95% CIs were calculated for TBI for detecting PAD – defined as one or more lower limb arteries with stenosis of ⩾ 50%.7 The diagnostic threshold for PAD using TBI was considered to be &lt; 0.70. Interpretation of postexercise TBI was evaluated firstly by using the diagnostic threshold of &lt; 0.70 for PAD, and secondly, if the postexercise value was &gt; 20% lower than the resting TBI.

Thus, guidelines do not support the use of CT or PET in routine cancer screening.3 However, the issue of cancer screening according to the clinical presentation of VTE is still debated, especially for bilateral deep vein thrombosis (DVT). This subgroup was outside the scope of the main studies that support current recommendations and previous reports have suggested that bilateral DVT was significantly associated with cancer.4 In this study, we aimed to report the prevalence of occult cancer diagnosed with systematic CT scan in patients admitted for unprovoked VTE according to the presence of bilateral DVT. We retrospectively reviewed the records of patients admitted to Rouen University Hospital, France, between 2007 and 2016, with a new diagnosis of symptomatic VTE (lower limb DVT, pulmonary embolism [PE], or both). Patients who underwent AP-CT (with thorax if CT pulmonary angiography [CTPA] was not initially performed) for cancer screening were included in the analysis. All patients admitted for PE and/or DVT were routinely investigated with bilateral whole leg colour-Doppler ultrasound (CDUS). A cancer was retrospectively adjudicated as occult if the patient with newly diagnosed cancer within 1 year after the thrombotic event was asymptomatic with normal physical examination and normal first-line test results (blood test, mammography, prostate-specific antigen [PSA]) at the time of VTE. A total of 891 patients were identified with lower limb DVT or PE. Of these, 435 (48.8%) events were provoked by transient, persistent risk factors or did not have AP-CT. Of the remaining 456 patients, mean age was 67.7 ± 16.3 years and 216 (47.3%) were male. PE was identified in 315 (69.1%) patients and DVT in 303 (66.44%), including bilateral DVT in 47 (10.3%) cases. A cancer was diagnosed in 83 (18.4%, 95% CI: 15.1–22.2%) patients at the time of the thrombotic event or within the 1-year follow-up.
