- Carotid Plaque Morphology in Asymptomatic Patients with and without Metabolic Syndrome(2017) CURY, Marcus Vinicius Martins; PRESTI, Calogero; BONADIMAN, Suellen Stevam Timotheo; CASELLA, Ivan Benaduce; BENABOU, Joseph Elias; SILVA, Erasmo Simao da; LUCCIA, Nelson de; PUECH-LEAO, PedroBackground: The aim of this study was to determine the impact of metabolic syndrome (MetS) on the morphology of carotid plaques, as evaluated using duplex ultrasound (DUS) with computer-assisted analysis. Methods: In this cross-sectional observational study, we analyzed 148 carotid artery plaques in asymptomatic patients. Data were obtained via clinical and laboratory examinations, and DUS was performed by a single operator. All plaques were scanned in a longitudinal fashion, and the best segment was selected, recorded, and evaluated using dedicated software. The main software-based analyses included gray-scale median (GSM) measurements and carotid plaque morphology histograms. Results: MetS was identified in 51.8% of patients. Comparisons of patients with MetS and patients without MetS indicated that the former patients used more classes of antihypertensive drugs (2.49 vs. 1.93; P = 0.004) and were treated with statins for a longer period (71.08 vs. 49.17 months; P = 0.003). Most patients of both types exhibited moderate carotid artery stenosis ranging from 50% to 69% (n = 62; 37.3%), and MetS was not associated with an increased prevalence of severe carotid artery stenosis. The mean GSM was greater in the MetS group than in the non-MetS group (74.18 vs. 61.63; P = 0.012). The histogram analysis revealed that there were lower quantities of blood and fat (2.91 vs. 3.88; P = 0.006; 10.21 vs. 15.08; P = 0.004, respectively) and more fibrous tissue (19.93 vs. 14.55; P = 0.015) in the carotid plaques of patients with MetS than in the carotid plaques of patients without MetS. Conclusions: The present study demonstrated that MetS did not affect the stenosis grade or did it lead to unstable carotid plaques.
- Endovascular Therapy Provides Similar Results of Bypass Graft Surgery in the Treatment of Infrainguinal Multilevel Arterial Disease in Patients with Chronic Limb-Threatening Ischemia in All GLASS Stages(2020) CASELLA, Ivan Benaduce; SARTORI, Camila Holanda; FAUSTINO, Carolina Brito; MARIZ, Maria Paula Vieira; PRESTI, Calogero; PUECH-LEAO, Pedro; LUCCIA, Nelson DeBackground: Extensive infrainguinal arterial disease still pose a challenge for technical and clinical success of percutaneous angioplasty. The purpose of this study was to compare the results of concomitant femoropopliteal and infrapopliteal percutaneous angioplasty/stenting (PTA/S) with distal bypass graft surgery (BGS) in patients with chronic limb-threatening ischemia (CLTI). Method: In a single-center retrospective investigation between 2011 and 2017, 668 revascularization procedures for CLTI were reviewed. Concomitant femoropopliteal and infrapopliteal disease was identified in 153 CLTI patients, treated with BGS (48) using autogenous veins as substitute or PTA/S in a single procedure (105). A subgroup of patients with complex, extensive arterial lesions (GLASS stage III) received additional analysis. Primary outcomes were limb salvage and survival. Results: The mean follow-up time was 21.4 months. Patients treated with PTA/S were significantly older and with predominance of females, diabetes and chronic kidney disease. Smoking was more common in patients treated with BGS. The BGS group showed a 36-month survival rate of 73.4%, whereas the PTA/S group presented a survival of 61.3% in the same interval (P = 0.25). The 36-month cumulative limb salvage rate was 53.3 and 59.7% for BGS and PTA/S, respectively (P = 0.24). For GLASS stage III patients, 36-month limb salvage rates were 54.4% for the PTA/S group and 50.2% for the BGS group (P = 0.29). Multivariate analysis pointed poor runoff status (all endovascular patients) and diabetes (GLASS III endovascular patients) as risk factors for limb loss. Conclusion: PTA/S and BGS presented similar results of limb salvage and survival in the treatment of concomitant femoropopliteal and infrapopliteal arterial disease in patients with CLTI, even for patients with extensive and complex arterial disease.

- Comparison Between a New Computer Program and the Reference Software for Gray-Scale Median Analysis of Atherosclerotic Carotid Plaques(2015) CASELLA, Ivan Benaduce; FUKUSHIMA, Rodrigo Bono; MARQUES, Anita Battistini de Azevedo; CURY, Marcus Vinicius Martins; PRESTI, CalogeroPurposeTo compare a new dedicated software program and Adobe Photoshop for gray-scale median (GSM) analysis of B-mode images of carotid plaques. MethodsA series of 42 carotid plaques generating 50% diameter stenosis was evaluated by a single observer. The best segment for visualization of internal carotid artery plaque was identified on a single longitudinal view and images were recorded in JPEG format. Plaque analysis was performed by both programs. After normalization of image intensity (blood=0, adventitial layer=190), histograms were obtained after manual delineation of plaque. Results were compared with nonparametric Wilcoxon signed rank test and Kendall tau-b correlation analysis. ResultsGSM ranged from 00 to 100 with Adobe Photoshop and from 00 to 96 with IMTPC, with a high grade of similarity between image pairs, and a highly significant correlation (R=0.94, p<.0001). ConclusionsIMTPC software appears suitable for the GSM analysis of carotid plaques. (c) 2014 Wiley Periodicals, Inc. J Clin Ultrasound43:194-198, 2015;
