Safety and Feasibility of the BYCROSS® Atherectomy Device for the Treatment of Femoropopliteal Arterial Obstructions: Single-Center Short-Term Outcomes.

Background: Endovascular techniques have gained preference over peripheral arterial bypass surgery due to their minimally invasive nature; however, endovascular treatments often show limited efficacy in arterial segments with a high atherosclerotic load. The use of atherectomy devices enables the removal of calcified plaque material and may promote arterial wall remodeling. This study assessed the technical success, safety, and feasibility of the BYCROSS® atherectomy device in femoropopliteal lesions. Methods: This single-center, retrospective cohort study analyzed elective patients undergoing BYCROSS® atherectomy for chronic peripheral arterial disease from March 2022 to May 2023. Patient data, procedural details, and outcomes were retrospectively collected from electronic patient records. The primary performance endpoints of this study were technical success, complications, and patency rates. Primary safety endpoints included 30-day and short-term major adverse limb events (MALEs), major adverse cardiovascular events (MACEs), and mortality rate. Results: The study included 19 patients (median age, 71 years; 63% male) with Fontaine class IIb (26%), III (21%), or IV (53%). The BYCROSS® atherectomy device was used to treat 22 limbs in the femoropopliteal tract, of which 11 lesions (50%) were occlusions and 11 were stenoses, with a median length of 24 cm (interquartile range: 17-38). Technical success was achieved in all cases: 4.5% required atherectomy only, 50% required additional balloon angioplasties, 41% required balloon angioplasties and stenting, and 4.5% required segments only stenting. Additional treatment of below-the-knee arteries was performed in 12 patients. Procedurally related complications (not limited to the use of the BYCROSS® device) occurred in 23% of limbs, including distal embolization and laceration. At 30 days, mortality was 5%, the MACE rate was 11%, and the MALE rate was 0%. The observed mortality rate was not directly related to the procedure. Patency (<50% restenosis at duplex ultrasound) was 83% at 30 days. Conclusions: The use of the BYCROSS® atherectomy device for the treatment of femoropopliteal lesions appears to be safe and feasible, with high technical success and low MALE and MACE rates in a challenging population with long-segment femoropopliteal lesions. Long-term follow-up in larger patient series is needed to confirm these findings and to determine the durability of this technique.

Wound, Ischemia, Foot Infection (Wifi) Classification System And Its Predictive Ability Concerning Amputation-Free Survival, Mortality And Major Limb Amputation In A Portuguese Population: A Single Center Experience.

Commonly used chronic limb-threatening ischemia (CLTI) classifications lack granularity and detail to precisely stratify patients according to risk of limb loss, expected revascularization benefit and mortality. The aim of this study is to evaluate in a Portuguese population the prognostic value of an updated CLTI classification based on Wound, Ischemia, and foot Infection (WIfI) proposed by the Society for Vascular Surgery. Single-center retrospective evaluation of prospectively collected data of consecutive patients with CLTI submitted to lower limb revascularization from January to December of 2017. All consecutive patients with chronic peripheral artery disease with ischemic rest pain or tissue loss were included. The exclusion criteria were patients with intermittent claudication, vascular trauma, acute ischemia, non-atherosclerotic arterial disease and isolated iliac intervention. The primary end-point was major limb amputation, mortality and amputation-free survival (AFS) at 30 days, 1 year and 2 year follow-up. Secondary end-points were minor amputation, wound healing time (WHT) and rate (WHR). A total of 111 patients with CLTI were submitted to infra-inguinal revascularization: 91 endovascular and 20 open surgery. After categorizing them according to the WIfI: 20 had stage 1 (18.52%), 29 stage 2 (26.85%), 38 stage 3 (35.19%) and 21 stage 4 (19.44%). Overall mortality rate was 1.8%, 17% and 22.3% at 30 days, 1 year and 2 years follow-up. Major amputation rate was 0.9%, 2.7% and 2.7% at 30 days, 1 year and 2 years follow-up. AFS rate was 97.3%, 82.1%, and 76.8% at 30 days, 1 year, 2 years follow-up. In multi-variable analysis, higher WIfI score was the only predictive factor for mortality and AFS. WIfI 3 and 4 were also associated with increased risk of non-healing ulcer. This study proved the prognostic value of the WIfI classification in a Portuguese population by showing an association between higher scores and increased mortality, lower AFS and non-healing ulcer.

Arterial and venous peripheral vascular assessment using wearable electro-resistive morphic sensors

Peripheral vascular diseases (PVDs) represent a significant burden on global human health and healthcare systems. With continued growth in obesity and diabetes, it is likely that the incidence of these conditions will increase. As many PVDs remain undiagnosed, low-cost and easy to use diagnostic methods are required. This work uses newly developed wearable electro-resistive morphic sensors to assess venous and arterial competence in the lower limbs of 36 healthy subjects. Comparison of this HeMo device was made to currently available benchtop light reflection rheography and photoplethymography devices. Results indicate that HeMo can detect the physiological signals of interest for both chronic venous insufficiency and peripheral arterial disease and all subjects were interpreted as healthy by each system. However, measurement repeatability of HeMo was highlighted as an issue that requires further system development. Furthermore, as HeMo captures changes in a section of limb circumference due to changes in underlying blood movement, rather than at a single point, the recorded signal is typically damped by comparison. This factor should be considered in any future developments.

Clinical recurrence and antiplatelet drug resistance among patients with lower limb ischemia.

There is a high prevalence rate of peripheral artery disease worldwide, with estimated cases exceeding 200 million. Most patients are under-diagnosed and under-treated, and there is a lack of knowledge regarding the best therapeutic regimen and therapy duration, which leads to many cases of recurrence, complications, and amputations. This study aims to explore clinical recurrence, which was defined as the worsening of chronic peripheral artery disease requiring hospital admission, and its relationship with antiplatelet drug resistance among patients with lower limb ischemia. This cohort study includes both retrospective and prospective recruitment of patients with chronic lower limb ischemia. Platelet aggregation tests were offered to the patients. Between February 2018 and November 2020, 147 patients were recruited from King Abdullah University Hospital and followed up for at least 1 year. Platelet aggregation tests were done for 93 patients who agreed to participate in this part of the study. The prevalence of chronic lower limb ischemia was higher in young male patients who are current smokers with co-morbid diseases such as hypertension, diabetes mellitus, and/or dyslipidemia. There was a significant association only of clinical recurrence with younger age (P = .011) and with low platelets count in severe stages of the disease (P = .047). No significant association was found in terms of laboratory resistance. The clinical recurrence rates of chronic lower limb ischemia were higher in younger patients and among those with low platelet counts in the severe stages of the disease. Despite the laboratory responsiveness to anti-platelet therapy, we observed significant clinical resistance and increased recurrence rates.

Sex differences in outcomes after revascularization for acute lower limb ischemia: Propensity score adjusted analysis.

Previous reports have suggested higher rates of mortality and amputation for female patients in acute lower limb ischemia (ALI). The aims of the present study were to investigate if there is a difference in mortality, amputation, and fasciotomy between the sexes. A retrospective cohort study of consecutive patients undergoing index revascularization for ALI between 2001 and 2018 was conducted. A propensity score was created through a logistic regression with female/male sex as an outcome. Cox regression analyses for 90-day and 1-year mortality, combining major amputation/mortality, and logistic regression for major bleeding and fasciotomy, were performed. All analyses were performed with and without adjusting for propensity score. A total of 709 patients were included in the study of which 45.9% were women. Mean age was 72.1years. Females were older and had higher rates of atrial fibrillation, embolic disease, and lower estimated glomerular filtration rate, while men more often had anemia and chronic peripheral arterial disease. Mortality at 1year was 21.2% for women and 14.7% for men. The adjusted hazard ratio for 1-year mortality was 0.99 (95% CI 0.67-1.46). Fasciotomy was performed in 7.1% of female and 12.8% of male patients; the adjusted odds ratio was 0.52 (95% CI 0.29-0.91). Sex was not found to be an independent risk factor for mortality or combined major amputation/mortality after revascularization for acute lower limb ischemia, whereas women had lower odds of undergoing fasciotomy. Whether women are underdiagnosed or do not develop acute compartment syndrome in the lower leg as often as men should be evaluated prospectively.

Clinical Practice Recommendations for Antithrombotic Management of Peripheral Artery Disease: An Indian Perspective

Abstract Currently, there are no guidelines or consensus recommendations on the antithrombotic management of peripheral artery disease (PAD) from an Indian perspective. In this article, we have summarized clinical practice recommendations on antithrombotic management of (i) asymptomatic chronic PAD (cPAD), (ii) symptomatic cPAD (intermittent claudication [IC] and chronic limb-threatening ischemia [CLTI]), and (iii) after revascularization (endovascular and surgical). An electronic search of the PubMed database was undertaken to identify relevant articles. Various combinations of keywords such as PAD, chronic peripheral arterial disease, asymptomatic chronic peripheral arterial disease, symptomatic chronic peripheral arterial disease, dual antiplatelet therapy, single antiplatelet therapy, dual pathway inhibition, antithrombotic, revascularization, endovascular, and surgical were used. Randomized controlled trials, case reports, practice guidelines, systematic literature reviews, and meta-analyses were screened and assessed. A roundtable meeting of experts (n = 13) was conducted to arrive at clinical practice recommendations. Experts made their decisions based on the evidence and guideline recommendations. In patients with asymptomatic cPAD and significant peripheral artery stenosis (PAS), long-term single antiplatelet therapy may be considered at the discretion of the clinician. There is no clear evidence in favor of long-term dual antiplatelet therapy in symptomatic cPAD. Experts agreed that low-dose rivaroxaban plus aspirin should be considered in patients with asymptomatic cPAD with &gt;50% PAS and conditions such as diabetes and polyvascular disease. This combination was also suggested in patients with IC, CLTI, postendovascular (stent based/nonstent), and surgical revascularization to reduce cardiovascular and limb ischemic risk, including major amputation in the absence of high bleeding risk or other contraindications.

Assessment of clinical and economic impact of rivaroxaban plus aspirin vs. aspirin alone as a secondary prophylaxis in patients with chronic and symptomatic peripheral arterial disease in the United States

AimThe objective in this study was to assess the clinical and economic implications of the inclusion of rivaroxaban as a secondary prophylaxis in patients with chronic or symptomatic peripheral artery disease (PAD) in the United States (US).MethodsA cost-consequence model was adapted to evaluate the economic impact of rivaroxaban plus aspirin in a hypothetical 1-million-member health plan. The model inputs were taken from multiple sources: efficacy and safety of rivaroxaban + aspirin vs. aspirin alone were abstracted from COMPASS and VOYAGER randomized clinical trials; the prevalence of chronic and symptomatic PAD and incidence rates of clinical events (major adverse cardiac events [MACE], major adverse limb events [MALE], and major bleeding), were abstracted from the analysis of claims data; healthcare costs of clinical events and wholesale acquisition costs for rivaroxaban were abstracted from the literature and Red Book, respectively (2022 USD). One-way sensitivity analyses and subgroup analyses were also conducted.ResultsOver one year, with a 5% uptake of rivaroxaban, the model estimated rivaroxaban + aspirin to reduce 21 MACE/MALE events in the PAD patient population. The reduction in these clinical events offsets the increased risk of major bleeding (16 additional events), demonstrating a positive health benefit of the rivaroxaban addition. These benefits led to a $0.27 incremental cost per member per month (PMPM) to a US plan. The major driver of the incremental cost was the cost of rivaroxaban. In a subgroup of patients with the presence of any high-risk factor (heart failure, diabetes, renal insufficiency, or history of vascular disease affecting two or more vascular beds), the incremental PMPM cost was $0.13.ConclusionsRivaroxaban + aspirin was found to provide positive net clinical benefit on the annual number of MACE/MALE avoided, with a modest increase in the PMPM cost.

Mortality and disability-adjusted life years in North Africa and Middle East attributed to kidney dysfunction: a systematic analysis for the Global Burden of Disease Study 2019.

The study aimed to estimate the attributable burden to kidney dysfunction as a metabolic risk factor in the North Africa and Middle East (NAME) region and its 21 countries in 1990-2019. The data used in this study were obtained from the Global Burden of Diseases (GBD) 2019 study, which provided estimated measures of deaths, disability-adjusted life years (DALYs), and other epidemiological indicators of burden. To provide a better insight into the differences in the level of social, cultural, and economic factors, the Socio-Demographic Index (SDI) was used. In the NAME region in 2019, the number of deaths attributed to kidney dysfunction was 296 632 (95% uncertainty interval: 249 965-343 962), which was about 2.5 times higher than in the year 1990. Afghanistan, Egypt, and Saudi Arabia had the highest, and Kuwait, Turkey, and Iran (Islamic Republic of) had the lowest age-standardized rate of DALYs attributed to kidney dysfunction in the region in 2019. Kidney dysfunction was accounted as a risk factor for ischemic heart disease, chronic kidney disease, stroke, and peripheral artery disease with 150 471, 111 812, 34 068, and 281 attributable deaths, respectively, in 2019 in the region. In 2019, both low-SDI and high-SDI countries in the region experienced higher burdens associated with kidney dysfunction compared to other countries. Kidney dysfunction increases the risk of cardiovascular diseases burden and accounted for more deaths attributable to cardiovascular diseases than chronic kidney disease in the region in 2019. Hence, policymakers in the NAME region should prioritize kidney disease prevention and control, recognizing that neglecting its impact on other diseases is a key limitation in its management.

Cryopreserved amniotic membrane in chronic nonhealing wounds: a series of case reports

A case series of the use of amniotic membrane (AM) for treating chronic nonhealing wounds. It presents five cases of polymorbid patients with a total of nine chronic nonhealing wounds. The patient group consisted of four men and one woman with various comorbidities, aged 45–72 years. The mean initial wound size was 15.8 cm2, and the mean time from the onset of the wound to the first application of AM was 122 weeks. The wounds were caused by chronic venous insufficiency and/or peripheral arterial disease. Wounds were treated in a standardized protocol. AM was applied weekly in the first month and then every two weeks. Photo documentation of the wound and microbiological colonization was carried out at each visit. In three out of five patients, the AM treatment effectively promoted healing up to complete wound closure. In two cases, the wounds stayed unhealed despite numerous AM applications. Pain relief was noted in all patients. The success of the treatment was closely tied to patient factors, such as adherence to the prescribed treatment regimen and individual patient characteristics. In some cases, treatment failure was observed, possibly due to underlying comorbidities, wound parameters, or poor patient compliance. AM treatment has the potential to become a viable treatment option for these nonhealing wounds. However, the effectiveness of the treatment may be influenced by various patient factors and the underlying cause of the wound. Therefore, it is crucial to have an individualized treatment plan that considers these particular factors.

Real-World Incidence of Adverse Clinical Outcomes Among People With Coronary Artery Disease and/or Peripheral Artery Disease in Relation to Vascular Risk in the United States

Presence of polyvascular disease, diabetes, heart failure, or renal insufficiency in patients with chronic coronary artery disease (CAD) and peripheral artery disease (PAD) are associated with increased risks of adverse events, including major adverse cardiovascular events (MACEs) and major adverse limb events (MALEs). In this retrospective observational study using administrative claims data from Optum's deidentified Clinformatics Data Mart Database from January 2016 to September 2021, we described the incidence rates of MACEs, MALEs, and major thrombotic vascular events in patients with CAD or PAD stratified by the presence of risk factors (i.e., polyvascular disease, diabetes, heart failure, or renal insufficiency). A total of 1,435,241 patients (77% CAD and 34% PAD) met the inclusion and exclusion criteria. Patients with 0 risk factors were deemed the low-risk group (47%; n=681,333) and patients with ≥1 risk factor were deemed the high-risk group (53%; n=753,908). The mean age was 71.8 and 73.6years, and 42% and 44% were female in the low- and high-risk groups, respectively. Compared with the low-risk group, the high-risk group had a 72% higher hazard of developing MACEs (adjusted hazard ratio 1.72, 95% confidence interval 1.70 to 1.74), 82% higher hazard of developing major thrombotic vascular events (1.82, 1.80 to 1.84), and 146% higher hazard of developing MALEs (2.46, 2.39 to 2.53) (all p <0.001). In conclusion, in patients with CAD or PAD, the presence of 1 or more risk factors was associated with higher risks of MACEs, MALEs, and major thrombotic vascular events, underscoring the need to improve management of underlying diseases in this population.

Who may benefit from low-dose Rivaroxaban plus Aspirin? Practical implications for outpatients with cardiovascular disease.

Despite the availability of effective preventive therapies based on guidelines, patients with vascular diseases continue to be at a high risk for recurrent ischemic events. Therefore, novel therapeutic strategies are required to further reduce the residual risk present in these patients at high risk. Platelet aggregation and fibrin organization are involved in arterial thrombosis, and rivaroxaban is capable of targeting both processes and has a synergistic effect when used in combination with acetylsalicylic acid (ASA), the so-called dual pathway inhibition (DPI). The COMPASS (Cardiovascular Outcomes for People Using Anticoagulation Strategies) trial showed that the DPI (a combination of rivaroxaban 2.5 mg/bid (vascular dose) and ASA 100 mg once daily), reduced cardiovascular death, stroke, or myocardial infarction by 24% in patients with chronic coronary artery disease (CAD) and peripheral artery disease (PAD). Subsequently, the VOYAGER PAD (Vascular Outcomes Study of ASA Along with Rivaroxaban in Endovascular or Surgical Limb Revascularization for PAD) trial confirmed the effectiveness of the vascular dose of rivaroxaban in patients with PAD after lower-extremity revascularization, compared to ASA alone. Therefore, DPI is recommended in patients with CAD (+/- PAD) or symptomatic PAD at high ischaemic risk. The purpose of this review is to examine the clinical benefits and practical implications of DPI in CAD and PAD patients.

Time-course evolution of functional performance during a 3-month supervised exercise training program in patients with symptomatic peripheral artery disease.

Functional performance is impaired in patients with peripheral artery disease (PAD). The effects of a supervised exercise training (SET) program on functional performance have yet to be clearly determined. The aim was to investigate the time-course evolution of functional performance during a 3-month SET program. Patients with chronic symptomatic PAD participating in a 3-month SET program were investigated. Six-minute walking distance (6MWD), the stair climbing test (SCT), and the Short Physical Performance Battery (SPPB) were assessed before SET, after the first and second months of SET, and following the SET program. The ankle- and toe-brachial indices were measured before and after the SET program. Ninety patients with PAD (age 65.4 ± 10.2 years) were analyzed. The 6MWD significantly improved after the first (+7%, p ⩽ 0.001) and second months (+13%, p ⩽ 0.001) and following SET (+14%, p ⩽ 0.001) compared to before the SET program. The 6MWD significantly improved after the 2nd month (+6%, p ⩽ 0.001) and following SET (+7%, p ⩽ 0.001) compared to after the first month of the SET program. The SPPB score and SCT performance significantly improved after the first (SPPB score: +9%, p ⩽ 0.001; SCT: +17%, p ⩽ 0.001) and second months (SPPB score: +11%, p ⩽ 0.001; SCT: +24%, p ⩽ 0.001) and following SET (SPPB score: +12%, p ⩽ 0.001; SCT: +25%, p ⩽ 0.001) compared to before the SET program. No significant differences were observed following SET compared to the second month of the SET program. Vascular parameters did not change significantly. A 3-month SET program improves several components of functional performance, and adaptations mainly occur during the 1st and 2nd months of the SET program.

Dual Antiplatelet Therapy or Antiplatelet Plus Anticoagulant Therapy in Patients with Peripheral and Chronic Coronary Artery Disease: An Updated Review.

Despite evidence-based therapies, patients presenting with atherosclerosis involving more than one vascular bed, such as those with peripheral artery disease (PAD) and concomitant coronary artery disease (CAD), constitute a particularly vulnerable group characterized by enhanced residual long-term risk for major adverse cardiac events (MACE), as well as major adverse limb events (MALE). The latter are progressively emerging as a difficult outcome to target, being correlated with increased mortality. Antithrombotic therapy is the mainstay of secondary prevention in both patients with PAD or CAD; however, the optimal intensity of such therapy is still a topic of debate, particularly in the post-acute and long-term setting. Recent well-powered randomized clinical trials (RCTs) have provided data in favor of a more intense antithrombotic therapy, such as prolonged dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor or a therapy with aspirin combined with an anticoagulant drug. Both approaches increase bleeding and selection of patients is a key issue. The aim of this review is, therefore, to discuss and summarize the most up-to-date available evidence for different strategies of anti-thrombotic therapies in patients with chronic PAD and CAD, particularly focusing on studies enrolling patients with both types of atherosclerotic disease and comparing a higher- versus a lower-intensity antithrombotic strategy. The final objective is to identify the optimal tailored approach in this setting, to achieve the greatest cardiovascular benefit and improve precision medicine.

Prevalence and Risk Factors of Helicobacter Pylori Infection in Asymptomatic Sudanese Population: A Cross-sectional Study

&#x0D; Background: Helicobacter pylori infections are a global problem, and constitute a known cause of gastrointestinal diseases such as gastritis, peptic ulcers, and gastric malignancies; they are also implicated in extra intestinal diseases, such as chronic urticarial and peripheral arterial disease. This study aims to determine the prevalence of Helicobacter pylori infections in asymptomatic individuals, and to estimate the risk factors of the infection.&#x0D; Methods: A cross-sectional study was conducted at Kassala Military Hospital in Sudan. A convenience sample of healthy individuals was used; 237 people were checked for eligibility. The individuals who were included to participate in the study consisted of healthy individuals, hospital staff, blood donors, and females arriving to receive antenatal care. A questionnaire was used to record the socio-demographics of the participants. Helicobacter pylori antibodies were detected in their blood by a rapid chromatographic immunoassay.&#x0D; Results: Of the 207 participants, 92 (44.4%) were male and 115 (55.6%) were female. The prevalence of the Helicobacter pylori infection was 48.1%, and was significantly associated with the water source (p = 0.02) of the participant and whether they shared a bed with their siblings during childhood (p = 0.016). There was no association found between the Helicobacter pylori infection and sanitation methods, gender, employment status, number of rooms in a dwelling, or level of education.&#x0D; Conclusion: The prevalence of the Helicobacter pylori infection was 48.1%, and the infection was significantly associated with the source of water and childhood sleeping arrangements.&#x0D;

Risk Factors for Ulceration in Diabetes Mellitus in the Preventive Foot Clinic at the Medical Center for Diabetes, Obesity, and Specialties, During the Period January-April 2022.

Introduction: Diabetes Mellitus is a conglomerate of metabolic alterations that chronically affect health. Neuropathy, previous ulcers, foot deformities, peripheral arterial disease, and chronic kidney disease are risk factors that predispose to the development of foot ulcers. It was carried out in order to determine risk factors for ulceration in people living with diabetes mellitus. Materials and methods: Descriptive observational study of 233 people who attended the Preventive Foot consultation at the Diabetes, Obesity and Specialties Medical Center, during the period January-April 2022. Information collected through a questionnaire that reported age, sex, marital status, time of diagnosis of diabetes mellitus, history of ulcer, amputation, bone deformity, chronic renal failure, neuropathy and peripheral arterial disease. Results: 60% female, 40% male, 60% ≥ 62 years. 39.6% with diagnosis time ≥16 years, 65.2%-foot deformity, 12.8% previous ulcer, 5.1% previous amputation, 10.3% chronic renal failure, 36% peripheral neuropathy and 31.3% peripheral arterial disease. 47.6% presented a very low risk, 27.5% moderate, 15% high risk and 9% low. Association time of diagnosis and neuropathy chi2= 8.993, p= &lt;0.029. Ulcer and amputation correlation rho=0.606, p=&lt; .001. Discussion: As risk factors predominated foot deformity, followed by diabetic neuropathy and peripheral arterial disease. With significant association between the time of diagnosis and neuropathy. With moderate direct proportional correlation between ulcer and previous amputation
