Purpose: The calcium score is a measure of vessel wall calcification and has clinical applications when studied in different vascular beds. The presence of vascular calcification in the arteries of the lower limbs is very common in patients with peripheral arterial disease; however, its relationship with the postoperative outcomes in patients undergoing lower limb revascularization is still poorly studied. The aim of this study is to evaluate association between the calcium score of lower limbs and the postoperative outcomes in patients with peripheral arterial disease undergoing revascularization procedures. Methodology: We retrospectively analyzed 88 lower limb revascularization procedures in 72 patients with critical limb ischemia who had enhanced computed tomography for preoperative evaluation. The calcium score was calculated, from the angiographic phase of preoperative computed tomography, in the segments of the aorta, iliac, femoropopliteal, and infrapopliteal. It was also calculated the calcium score of the operated limb, and the total calcium score using a standardized method. The outcomes evaluated were the occurrence of acute myocardial infarction, amputation, patency, technical success, and death from any cause. Patients were followed up through a 12 month period. Results: Among the 88 procedures performed, 31 (43.1%) lesions were classified as Trans-Atlantic Inter-Society Consensus Document II D. There were 66 (75%) endovascular procedures, 16 (18.2%) open surgery, and 6 (6.8%) hybrid interventions. No statistically significant relationship was found between the calcium score of the segments (aorta, iliac, femoropopliteal, infrapopliteal, the operated limb, and total calcium score) and the outcomes of acute myocardial infarction, amputation, patency, and technical success in any of the periods analyzed. The calcium score of the operated limb was higher in patients who died within 30 days and 6 months (6571 vs 2590.6; p=0.026) and (5227.8 vs 2335.3; p=0.036). Conclusion: A standardized calcium score calculation method with the angiographic phase of the computed tomography is feasible and reproducible. Higher values of the calcifications of the operated limb are related to a greater chance of death in the postoperative period. The calcium score of the operated limb can be considered as a marker of clinical severity and prognosis in this group of patients

Abstract These case reports aim to show that hyperfibrinogenemia is a risk factor for the progression and prognosis of peripheral arterial disease (PAD), in patients with and without diabetes mellitus type 2. We present a patient with PAD who has type 2 diabetes mellitus, who has previously been repeatedly treated for lower limb ischemia with multiple vascular surgeries performed. A few weeks before admission the patient developed critical lower limb ischemia, which was treated with an iliaco-popliteal and femorofemoral bypass. The patient had elevated serum fibrinogen values. In the current admission, renewed left limb ischemia was diagnosed, and surgically evaluated with a recommendation for amputation of the left limb as a surgical recommendation. Our second patient had a stable intermittent claudication, dyslipidemia and hyperfibrinogenemia. He was successfully treated for those risk factors. Regular monitoring of the patient showed improved claudication distance and quality of life Our case reports, supported by a literature review, demonstrate that hyperfibrinogenemia is a possible risk factor for progression and the prognosis of PAD.

Intermittent claudication is a symptom of atherosclerosis of the lower limbs (peripheral arterial disease (PAD)) and is characterized by pain and cramps of lower limb muscles during exercise. Claudication leads to a reduction in physical activity of patients. PAD is a systemic disease. Atherosclerotic lesions located in the arteries of the lower limbs not only pose the risk of the ischemic limb loss, but above all, they are an important prognostic factor. Patients with claudication are at significant risk of cardiovascular complications such as infarcts or strokes. Comprehensive rehabilitation of patients with intermittent claudication based on the current TASC II (Inter-Society Consensus for the Management of Peripheral Arterial Disease) guidelines, ESC (European Society of Cardiology) guidelines, and AHA (American Heart Association) guidelines includes supervised treadmill training, training on a bicycle ergometer, Nordic Walking, resistance exercises of lower limb muscles, and exercises of upper limbs. A trained, educated, and motivated patient has a chance to improve life quality as well as life expectancy.

AbstractCritical limb ischemia (CLI) is the most severe form of peripheral arterial disease (PAD) that may result in limb loss and even death; thus, the fast and proper treatment should be employed as earlier as possible to prevent these catastrophic consequences. Arterial revascularization is almost always an indispensable treatment option for CLI. Although both endovascular and surgical revascularization procedures have an important role, nowadays, the hybrid revascularization as a combination of these revascularization procedures has also gained increasing popularity in the treatment of patients with CLI. This review provides an update on the arterial revascularization strategies for the treatment of CLI.

Abstract Background: Risk factors for peripheral arterial disease are generally the same as those responsible for the ischemic heart disease and in both cases are overlapping risk factors involved in the etiology of atherosclerosis, such as smoking, dyslipidemia, diabetes and hypertension. Case report: We present a case of a 61 years old male, whose ischemic peripheral symptoms began in 2003, at the age of 49, presenting as a Leriche syndrome. The patient was subjected to first revascularization procedure consisting in aortic-bifemoral grafting in the same year. General examination revealed no risk factors except smoking. Only a year after, he returns with critical right lower limb ischemia due to bypass thrombosis, therefore two thrombectomies were performed followed by a right side femoro-popliteal bypassing with Dacron prosthesis. The patient’s condition was good until 2008 when a femoro-popliteal bypass using inverted autologus saphenous vein was imposed due to occlusion of the previous graft. In 2013 the patient was readmitted to hospital with left lower limb critical ischemia. A femoro-popliteal bypass was performed, followed by two thrombectomies and the amputation of the left thigh. Up to this date, the patient kept smoking. Discussions: Although our patient has a low/medium risk level of atherosclerosis by Framingham score and a minimum Prevent III score, all the surgical revascularization procedures were not able to avoid the amputation. Conclusions: There are enough reasons to believe that smoking as a single risk factor can strongly influence the unfavorable progression to amputation in patients with peripheral arterial disease.

Objectives: Peripheral arterial disease (PAD) leads to narrowing and hardening of arteries which leads to increased risk of lower extremity amputation. Hence, the accuracy of non-invasive diagnostic methods such as calcium scoring and color Doppler needs to be assessed in comparison to the gold standard dual-energy computed tomography (DECT) angiography. This study aims to evaluate the accuracy of color Doppler and calcium scoring when compared to DECT angiography in the assessment of PAD of the lower limb. It is a cross- sectional retrospective study. Material and Methods: The study included 55 patients aged between 40 and 70 years. All the patients with symptoms suggestive of PAD underwent color Doppler study of lower limb arterial system. Afterward, the patient underwent CT angiography. The first plain images were taken for calcium scoring following which contrast was given and further images were taken. Results: As compared to CT angiography assessment, Doppler assessment was 88.1% sensitive but only 69.2% specific with diagnostic accuracy of 83.6%. For angiographically detected atheromatous changes, color Doppler had sensitivity and specificity of 86.2% and 76.9%. The derived cutoff value >149.1 of calcium score in lower limb arteries was in 100% agreement with CT angiography detected PAD, whereas, for atheromatous changes, total calcium score at a cutoff value of >842.2 had sensitivity and specificity of 75.9% and 80.8%. Conclusion: Calcium scoring as compared to color Doppler has a higher diagnostic efficacy for the detection of DECT angiography confirmed PAD, whereas calcium score lacks adequate sensitivity at projected cutoff in the evaluation of atheromatous changes.

Background: Vascular inflammation plays a crucial role in peripheral arterial disease (PAD), although the role of the mediators involved has not yet been properly defined. The aim of this work is to investigate gene expression and plasma biomarkers in chronic limb-threating ischemia (CLTI). Methods: Using patients from the GHAS trial, both blood and ischemic muscle samples were obtained to analyze plasma markers and mRNA expression, respectively. Statistical analy-sis was performed by using univariate (Spearman, t-Student, X2) and multivariate (multiple lo-gistic regression) tests. Results: 35 patients were available at baseline (29 for mRNA expression). Baseline characteristics (mean): Age:71.4±12.4 (79.4% male); TNF-α:10.7±4.9; hs-CRP:1.6±2.2; Neutrophil-to-lymphocyte ratio (NLR):3.5±2.8. Plasma TNF-α was found elevated (≥8.1) in 68.6% of patients, while high hs-CRP (≥0.5) in 60.5%. Diabetic patients with high level of inflammation showed significantly higher levels of NOX4 expression at baseline (p=0.0346). Plasma TNF-α had a negative correlation with eNOS expression (-0.5, p=0.015) and hs-CRP with VEGF-A (-0.63, p=0.005). The expression of NOX4 was parallel to that of plasma TNF-α (0.305, p=0.037), especial-ly in DM. Cumulative mortality at 12-month was related to NLR ≥3 (p=0.019) and TNF-α ≥8.1 (p=0.048). The best cut-off point for NLR to predict mortality was 3.4. Conclusions: NOX4 and TNF-α are crucial for the development and complications of lower limb ischemia, especially in DM. hs-CRP could have a negative influence on angiogenesis too. NLR and TNF-α represent suita-ble markers of mortality in CLTI. These results are novel because they connect muscle gene expres-sion and plasma information in patients with advanced PAD, deepening the search of new and ac-curate targets for this condition.
