          Abstract

          Background

          Determination of predictors that can affect development of atherosclerosis progression in the postoperative period is an urgent problem in vascular surgery.

          Objectives

          Integrated assessment of markers of apoptosis and cell proliferation in atherosclerotic lesions and their progression after surgery in patients with peripheral arterial diseases.

          Methods

          The investigation included 30 patients with stage IIB-III peripheral arterial disease. All patients have undergone open surgical interventions on the arteries of the aorto-iliac and femoral-popliteal segments. During these interventions, intraoperative specimens were obtained from the vascular wall with atherosclerotic lesions. The following values were evaluated: VEGF А165, PDGF BB, and sFas. Samples of normal vascular wall were obtained from post-mortem donors and used as a control group.

          Results

          The levels of Bax and p53 were increased (p<0.001) in samples from arterial wall with atherosclerotic plaque, while sFas values were reduced (p<0.001), compared to their levels in control samples. Values of PDGF BB and VEGF A165 were 1.9 and 1.7 times higher in atherosclerotic lesion samples (p=0.001), in comparison with the control group. The levels of p53 and Bax were increased against a background of reduced sFas levels in samples with progression of atherosclerosis compared to their baseline values in samples with atherosclerotic plaque (p<0.05).

          Conclusions

          Initially increased values of the Bax marker against a background of reduced sFas values in vascular wall samples from patients with peripheral arterial disease is associated with risk of atherosclerosis progression in the postoperative period.

          Resumo

          Contexto

          A determinação de preditores que possam influenciar o desenvolvimento da progressão da aterosclerose no período pós-operatório é um problema urgente em cirurgia vascular.

          Objetivos

          Realizar uma avaliação integral de marcadores de apoptose e proliferação celular nas lesões ateroscleróticas e sua progressão após cirurgia em pacientes com doenças arteriais periféricas.

          Métodos

          A investigação incluiu 30 pacientes com doenças arteriais periféricas de estágio IIB-III. Todos os pacientes foram submetidos a intervenções operatórias abertas nas artérias dos segmentos aorto-ilíaco e fêmoro-poplíteo. Durante a intervenção, foi obtido material intraoperatório da parede vascular com lesões ateroscleróticas. Foram avaliados os seguintes valores: VEGF A165, PDGF BB e sFas. Como grupo controle, amostras de parede vascular normal foram obtidas de doadores post-mortem.

          Resultados

          O nível de Bax e p53 (p < 0,001) em amostras de parede arterial com placa aterosclerótica estava elevado em meio a valores reduzidos de sFas (p < 0,001) em comparação ao grupo controle. Os valores de PDGF BB e VEGF A165 foram 1,9 e 1,7 vezes maiores, respectivamente, nas amostras com lesão aterosclerótica (p = 0,001) do que no grupo controle. O nível de Bax e p53 e Bax estava elevado no contexto de nível reduzido de sFas em amostras com progressão da aterosclerose em comparação com seus valores basais em amostras com placa aterosclerótica (p < 0,05).

          Conclusões

          Níveis inicialmente elevados do marcador Bax no contexto de valores reduzidos de sFas na parede vascular em pacientes com doença arterial periférica estão associados a risco de progressão da aterosclerose no período pós-operatório.

          Global vascular guidelines on the management of chronic limb-threatening ischemia

          Chronic limb-threatening ischemia (CLTI) is associated with mortality, amputation, and impaired quality of life. These Global Vascular Guidelines (GVG) are focused on definition, evaluation, and management of CLTI with the goals of improving evidence-based care and highlighting critical research needs. The term CLTI is preferred over critical limb ischemia, as the latter implies threshold values of impaired perfusion rather than a continuum. CLTI is a clinical syndrome defined by the presence of peripheral artery disease (PAD) in combination with rest pain, gangrene, or a lower limb ulceration >2 weeks duration. Venous, traumatic, embolic, and nonatherosclerotic etiologies are excluded. All patients with suspected CLTI should be referred urgently to a vascular specialist. Accurately staging the severity of limb threat is fundamental, and the Society for Vascular Surgery Threatened Limb Classification system, based on grading of Wounds, Ischemia, and foot Infection (WIfI) is endorsed. Objective hemodynamic testing, including toe pressures as the preferred measure, is required to assess CLTI. Evidence-based revascularization (EBR) hinges on three independent axes: Patient risk, Limb severity, and ANatomic complexity (PLAN). Average-risk and high-risk patients are defined by estimated procedural and 2-year all-cause mortality. The GVG proposes a new Global Anatomic Staging System (GLASS), which involves defining a preferred target artery path (TAP) and then estimating limb-based patency (LBP), resulting in three stages of complexity for intervention. The optimal revascularization strategy is also influenced by the availability of autogenous vein for open bypass surgery. Recommendations for EBR are based on best available data, pending level 1 evidence from ongoing trials. Vein bypass may be preferred for average-risk patients with advanced limb threat and high complexity disease, while those with less complex anatomy, intermediate severity limb threat, or high patient risk may be favored for endovascular intervention. All patients with CLTI should be afforded best medical therapy including the use of antithrombotic, lipid-lowering, antihypertensive, and glycemic control agents, as well as counseling on smoking cessation, diet, exercise, and preventive foot care. Following EBR, long-term limb surveillance is advised. The effectiveness of nonrevascularization therapies (eg, spinal stimulation, pneumatic compression, prostanoids, and hyperbaric oxygen) has not been established. Regenerative medicine approaches (eg, cell, gene therapies) for CLTI should be restricted to rigorously conducted randomizsed clinical trials. The GVG promotes standardization of study designs and end points for clinical trials in CLTI. The importance of multidisciplinary teams and centers of excellence for amputation prevention is stressed as a key health system initiative.
