RESUMO
All guidelines worldwide strongly recommend exercise as a pillar of the management of patients affected by lower extremity peripheral artery disease (PAD). Exercise therapy in this setting presents different modalities, and a structured programme provides optimal results. This clinical consensus paper is intended for clinicians to promote and assist for the set-up of comprehensive exercise programmes to best advice in patients with symptomatic chronic PAD. Different exercise training protocols specific for patients with PAD are presented. Data on patient assessment and outcome measures are narratively described based on the current best evidence. The document ends by highlighting disparities in access to supervised exercise programmes across Europe and the series of gaps for evidence requiring further research.

The inferior vena cava (IVC) and superior vena cava are the main conduits of the systemic venous circulation into the right atrium. Developmental or procedural interruptions of vena cava might predispose to stasis and deep vein thrombosis (DVT) distal to the anomaly and may impact the subsequent rate of pulmonary embolism (PE). This study aimed to review the various etiologies of developmental or procedural vena cava interruption and their impact on venous thromboembolism. A systematic search was performed in PubMed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines per each clinical question. For management questions with no high-quality evidence and no mutual agreements between authors, Delphi methods were used. IVC agenesis is the most common form of congenital vena cava interruption, is associated with an increased risk of DVT, and should be suspected in young patients with unexpected extensive bilateral DVT. Surgical techniques for vena cava interruption (ligation, clipping, and plication) to prevent PE have been largely abandoned due to short-term procedural risks and long-term complications, although survivors of prior procedures are occasionally encountered. Vena cava filters are now the most commonly used method of procedural interruption, frequently placed in the infrarenal IVC. The most agreed-upon indication for vena cava filters is for patients with acute venous thromboembolism and coexisting contraindications to anticoagulation. Familiarity with different forms of vena cava interruption and their local and systemic adverse effects is important to minimize complications and thrombotic events.

RESUMO
Background: The COVID-19 pandemic has led to significant disruptions in chronic disease care and forced people to stay at home. The effects of such issues on outpatients with lower extremity peripheral artery disease (PAD) remain unknown. Patients and methods: Single-centre, retrospective-prospective study conducted in a Swiss University Hospital. Patients with PAD were included between May 1 and July 31, 2020, with a follow-up visit at 12 months. Upon both visits, the Leriche-Fontaine PAD stage was recorded, and study participants underwent ankle-brachial index (ABI) calculation to assess limb perfusion. Functional capacities were assessed through the 6-minute walking and treadmill tests. Major adverse cardiovascular (MACE) and limb events (MALE) were recorded. Data collected during the pandemic were compared with the pre-pandemic period (January 1, 2019-April 30, 2020). Results: Overall, 259 patients were included. Mean age was 69 years and male sex was prevalent (69.1%). Odds of experiencing a degradation in PAD stage were lower during the pandemic than before (odds ratio [OR]: 0.43; 95% confidence interval [CI]: 0.21-0.87; p = 0.018). No significant difference was found between periods in terms of ABI trends. Both pain-free walking time at treadmill test (p = 0.003) and maximal pain intensity at 6-minute walking test (p = 0.001) significantly improved during the pandemic. Compared with the pre-pandemic period, during the pandemic patients were hospitalized less frequently (p = 0.028) and were less likely to undergo elective limb revascularization (p<0.001). No significant difference was found between periods in terms of MALE (p = 0.311), whereas non-fatal strokes were less frequently reported during the pandemic (p = 0.043). Conclusion: In a cohort of outpatients with PAD, we found no evidence of clinical deterioration during the pandemic compared with the pre-pandemic period, though rates of adverse events were nonnegligible in both periods. In case of future pandemics, patients with PAD should be encouraged to maintain an active lifestyle while being closely monitored to avoid clinical worsening.
RESUMO
Endovascular interventions and diagnostic examinations using iodinated contrast media (ICM) are standard of care in current vascular medicine. Although ICM use is generally considered safe, it may be associated with adverse reactions, vary from minor disturbances to rare, but severe life-threatening complications. This position paper of European Society of Vascular Medicine integrates current knowledge and summarizes the key information related to the use of intravascular ICM, serving as recommendation on prevention and management of acute, late, and very late adverse reactions. It should help the health professionals in all fields of vascular medicine to make decisions in daily practice for safe use of contrast media.

This study aimed to investigate the feasibility of a peripheral artery disease (PAD)-adapted 30-20-10 Nordic walking session in patients with symptomatic PAD and to compare the cardiovascular response of this new training session to a traditional walking (TW) and 4â ×â 4 minutes Nordic walking session. This is a prospective observational study. Patients with Fontaine stage II PAD were included. Patients participated in Nordic walking sessions, which were randomly assigned as TW, 4â ×â 4 minute intervals, and peripheral artery disease adapted 30-20-10 exercise session (PAD-adapted 30-20-10 sessions). PAD-adapted 30-20-10 and 4â ×â 4 minutes sessions consisted of 4 repetitions of 4 minutes of effort followed by 3 minutes of passive recovery. PAD-adapted 30-20-10 session was characterized by 4 continuous 1-min repetitions at 3 different walking speeds [high (30 seconds), moderate (20 seconds) and low (10 seconds)]. During the 4â ×â 4 minutes session, patients were asked to cover the maximal distance at a constant speed. During TW session, patients were asked to walk at a speed inducing moderate-to-severe claudication pain. Heart rate, rating of perceived exertion (RPE) and claudication pain intensity using a visual analog scale were assessed. The perceived enjoyment of each session was assessed using a visual analog scale ranging from 0 (not enjoyable) to 10 (very enjoyable). Eleven patients with chronic symptomatic PAD were included (62â ±â 13 years; 54% women). The mean heart rate during the time of effort was significantly higher in PAD-adapted 30-20-10 group than in 4â ×â 4 minutes and TW groups (127â ±â 12, 122â ±â 12, 114â ±â 11 bpm, respectively; Pâ ≤â .001). The mean rating of perceived exertion (16â ±â 1, 15â ±â 1, 13â ±â 1; Pâ ≤â .001) and claudication pain intensity (8â ±â 1, 7â ±â 1; 7â ±â 1 mm; Pâ ≤â .019) were significantly higher during PAD-adapted 30-20-10 sessions than during 4â ×â 4 minutes and TW sessions. The perceived enjoyment was similar among sessions (8.7â ±â 1.6 for TW, 8.6â ±â 1.7 for 4â ×â 4 minutes, and 8.8â ±â 1.8 mm for PAD-adapted 30-20-10 sessions; Pâ =â .935). The PAD-adapted 30-20-10 session is feasible and induces higher cardiovascular stimulation and claudication pain than 4â ×â 4 minutes and TW procedures in patients with symptomatic PAD. Despite these different responses, a similar perceived enjoyment among the sessions has been shown. Future investigations are needed to examine the effects of this new training session in these patients.

Patients with symptomatic peripheral artery disease (PAD) have been shown to present balance disorders and a history of falling, which are associated with functional and daily life impairments. Although postural control improvement is an important outcome, the benefits of supervised exercise training (SET) on postural control have been seldom investigated in these patients. This article investigates the effects of SET on traditional measures of postural control and on stabilogram-diffusion analysis (SDA) parameters in patients with symptomatic PAD. Patients with symptomatic chronic lower limb claudication were investigated. All subjects who completed the 3-month multimodal SET program and postural control assessment before and after SET were included. Center of pressure trajectory analysis and SDA parameters were investigated using a posturographic platform. Patients were instructed to stand on the platform and maintain balance to their best ability. Treadmill pain-free (PFWD) and maximal (MWD) walking distances were also assessed prior and following SET. Forty-four patients with PAD (65.2 ± 9.8 years, 34% women) were investigated. All postural control parameters were unchanged following SET, except the length of center of pressure displacement as a function of the surface of center of pressure trajectory (LFS), which was significantly increased (before SET: 1.4 ± 0.4; after SET: 1.5 ± 0.5; p = 0.042). PFWD (before SET: 103.5 ± 77.9 m; after SET: 176.8 ± 130.6 m; p ≤ 0.001) and MWD (before SET: 383.6 ± 272.0 m; after SET: 686.4 ± 509.0 m; p ≤ 0.001) significantly improved following SET. The increased LFS suggests a better postural control accuracy following SET in patients with symptomatic PAD.
RESUMO
Acquired arteriovenous fistula (AVF) in the hand can occur after trauma, fracture, or surgery. It is a rare condition, and only a few cases have been reported in the literature. Clinically they appear as palpable or painful lesions that persist long after the local hematoma has resolved. We report a case of a young patient presenting with long-standing and invalidating pain of the hand caused by a post-traumatic AVF, treated with percutaneous endovascular laser ablation.
RESUMO
INTRODUCTION: Supervised exercise training is among the first-line therapies for patients with peripheral artery disease (PAD). Current recommendations for exercise include guidance focusing on claudication pain, programme and session duration, and frequency. However, no guidance is offered regarding exercise training intensity. This study aims to compare the effects of 12-week-long supervised walking exercise training (high-intensity interval training (HIIT) vs moderate-intensity exercise (MOD)) in patients with chronic symptomatic PAD. METHODS AND ANALYSIS: This study is a monocentric, interventional, non-blinded randomised controlled trial. 60 patients (30 in each group) will be randomly allocated (by using the random permuted blocks) to 12 weeks (three times a week) of HIIT or MOD. For HIIT, exercise sessions will consist of alternating brief high-intensity (≥85% of the peak heart rate (HRpeak)) periods (≤60 s) of work with periods of passive rest. Patients will be asked to complete 1 and then 2 sets of 5-7 (progressing to 10-15×60 s) walking intervals. For the MOD group, exercise training sessions will consist of an alternation of periods of work performed at moderate intensity (≤76% HRpeak) and periods of passive rest. Interventions will be matched by training load. The primary outcome will be the maximal walking distance. Secondary outcomes will include functional performance, functional capacity, heath-related quality of life, self-perceived walking abilities, physical activity and haemodynamic parameters. ETHICS AND DISSEMINATION: The Angiof-HIIT Study was approved by the Human Research Ethics Committee of the Canton de Vaud (study number: 2022-01752). Written consent is mandatory prior to enrolment and randomisation. The results will be disseminated via national and international scientific meetings, scientific peer-reviewed journals and social media. TRIAL REGISTRATION NUMBER: NCT05612945.

BACKGROUND: Increased arterial tortuosity has been associated with various cardiovascular complications. However, the extent and role of arterial tortuosity in non-atherosclerotic vascular diseases remain to be fully elucidated. This study aimed to assess arterial tortuosity index (ATI) in patients with non-atherosclerotic vascular diseases and the associated factors. METHODS: This is a retrospective analysis of patients with non-atherosclerotic vascular diseases referred to the Malformation and Rare Vascular Disease Center at the University Hospital in Lausanne (Switzerland). Computed tomography angiography (CTA) images performed between October 2010 and April 2022 were retrieved and the aortic tortuosity index (ATI) was calculated. Patients were classified based on diagnosis into the following groups: arterial dissection & aneurysm, arteritis & autoimmune disease, hereditary connective tissue diseases, and fibromuscular dysplasia (FMD). Univariate and multivariate logistic regression analysis was used to determine potentially relevant predictors of aortic tortuosity. RESULTS: The mean age upon computed tomography angiography (CTA) was 46.8 (standard deviation [SD] 14.6) years and 59.1% of the patients were female. Mean ATI was higher in patients over 60 years old (1.27), in those with arterial aneurysms (mean: 1.11), and in those diagnosed with hypertension (mean: 1.13). When only patients over 60 years old were considered, those diagnosed with connective tissue diseases had the highest ATI. At multivariate regression analysis, increasing age (p < 0.05), presence of arterial aneurysms (p < 0.05), and hypertension (p < 0.05) were independently associated with ATI. CONCLUSIONS: The ATI may be a promising tool in diagnostic evaluation, cardiovascular risk stratification, medical or surgical management, and prognostic assessment in several non-atherosclerotic vascular conditions. Further studies with longitudinal design and larger cohorts are needed to validate the role of ATI in the full spectrum of vascular diseases.
