“…In equine females, age had a positive correlation with the vessels' longitudinal wall; similar to what was found by Aguiar (2015) in the Quarter horse breed, and negative correlations with body mass and the base of the neck. It was found that the age of equine females did not have significant correlations with the diameters of the common carotid arteries, unlike the results obtained by Aguiar (2015) with equines and Krejza et al (2006), Torres et al (2007), Freitas et al (2008) and Coll et al (2013) in humans.…”

“…However, atherosclerotic plaques are not so frequent in veterinary medicine, although there are already reports of its incidence in dogs and horses (Hess et al 2003, Rosa et al 2003, Ribeiro & Shintaku 2004, Aguiar et al 2014. Another disturbance that affects the common carotid arteries is stenosis secondary to traumatic, neoplastic or inflammatory processes (Bonamigo & Lucas 2007, Freitas et al 2008, Kandiah et al 2014. Other diseases that can also affect these great arteries are atherosclerosis, stiffening secondary to senility or chronic lesions and dissection (Mendes & Themudo Barata 2008).…”

As age increases, changes in cardiovascular anatomy and physiology occur, even in the absence of disease. Thus, studies of vessel hemodynamics are considered primordial to detect any cardiovascular changes. The objective of this study has been to describe the parameters of B-mode and spectral Doppler ultrasonography in the evaluation of the common carotid arteries of 11 equine and 11 mules, and correlate with age, body mass and neck circumferences. The diameters, intima - media thickness (IMT), resistivity index (RI), pulsatility index (PI), systolic velocity (SV), diastolic velocity (DV), maximum velocity (MV), vascular flow index (VFI), body mass, age, circumference and neck length. Ultrasonographic variables were evaluated in three different region called cranial, middle and caudal. Equine females presented higher values regarding the body mass, age and neck length, as compared to the neck circumferences of the animals, those of the mules were superior. The age of the mules had a positive correlation with the body mass, diameter and neck circumferences, it has a negative correlation between age and vessel diameters. The body mass of the mules had a positive correlation with age and vessel diameters, and with vessel diameters and neck circumferences in equine females. The RI and PI variables had a positive correlation with body mass for mules, and with age for equine females. The DV had a negative correlation with body mass for both equine and mule females. Regarding the variables MV and VFI, age correlated negatively for mules, while it was not significant for equine females. It found a difference between equine females and mules in the correlations performed, with body mass, age, neck circumferences and between B-mode and Doppler ultrasonography variables.

“…Echography has been established as a fundamental feature in the diagnosis, treatment, preoperative mapping, and followup of extracranial carotid artery stenosis [1][2][3][4][5][6][7][8][9][10] . Initially, in the 1980' s, color-duplex echography (or Doppler ultrasonography -DUS) was used to select patients for contrast angiography, the method traditionally used for carotid endarterectomy planning.…”

Context: Doppler ultrasonography is an established method for diagnosis, preoperative imaging and follow-up of extracranial carotid artery disease. Objetive: The evaluation of gender differences in carotid artery bifurcation Doppler ultrasonography mapping. Methods: High resolution Doppler ultrasonography of 500 carotid bifurcations was performed in 192 women and 308 men before surgical treatment. Gender differences were analyzed based on B-mode, color-flow, duplex doppler transverse and longitudinal images. Diameter percent stenoses, plaque length, distal internal and common carotid artery diameters, and distance from the carotid bifurcation to the ear lobe were compared. Mean, standard deviation, minimum and maximum values were described. Statistical comparisons were performed based on Student' s t and χ2 tests. Results: Carotid stenoses averaged 70±11% (30-95%) in women and 72±12% (40-98%) in men (p=0.013). The prevalence of 90-99% stenosis was greater in men, 14.3 vs 7.8% (p=0.029). Carotid plaques were longer in men, 2.3±0.8 vs 1.9 ±0.6 cm (p<0.001). Mean diameters of the distal internal carotid artery, 4.9±0.9 vs 4.6 ±0.8 mm, and of the common carotid artery, 7.6±1.3 vs 7.1±1.4 mm, were greater in men (p=0.001). Th e distance from the ear lobe to the bifurcation was also greater in men, 5.9±1.1 vs 5.3±0.9 cm (p<0.001). Conclusions: Doppler ultrasonography preoperative mapping demonstrated that the parameters measured were greater in men than in women. Detailed planning of carotid plaque treatment must take into consideration individual differences such as those associated with the patient' s gender.Keywords: ultrasonography; carotid stenosis; surgery. ResumoContexto: A ecografia das artérias carótidas extracranianas já se estabeleceu como método diagnóstico de imagem pré-operatória, e para seguimento de pacientes. Objetivo: Avaliar diferenças do mapeamento ecográfico em função do gênero masculino ou feminino dos pacientes. Métodos: Ultrassonografia de alta resolução foi realizada antes do tratamento cirúrgico de 500 bifurcações carotídeas em 192 mulheres e 308 homens. Análise de diferenças baseadas no gênero foi feita em imagens modo B e fluxo a cor, transversal e longitudinal, e medidas duplex doppler de velocidades. Porcentual de estenose expressa em redução de diâmetro, comprimento de placa, diâmetros das artérias carótida interna distal e comum, e distância da bifurcação ao lóbulo da orelha foram comparados. Média, desvio padrão, mínimo e máximo foram descritos. Comparações estatísticas foram baseadas em testes t de Student e do χ 2 . Resultados: Estenoses carotídeas mediram 70±11% (30-95%) em mulheres e 72±12% (40-98%) em homens (p=0,013). Prevalência de estenoses no intervalo 90-99% foi mais alta em homens, 14,3 vs 7,8% (p=0,029). As placas foram mais extensas nos homens, 2,3±0,8 vs 1,9±0,6 cm (p<0,001). O diâmetro médio foi maior nos homens, tanto da carótida interna distal, 4,9±0,9 vs 4,6±0,8 mm, como da carótida comum, 7,6±1,3 vs 7,1±1,4 mm (p=0.001). A distância da bifurcação ao lóbulo da...

“…This exam allows the visualization of the whole dentoalveolar region and adjacent structures in one film, with images made in small cuts or sliced areas without overlapping of the structures located above or below the cut. Without the overlapping of the structures, it is possible to visualize the plaques of atheroma through radiopacity images with different shape on the soft tissue (Freitas et al, 2009;Abreu et al, 2011). These aspects motivated the recent research, which aimed to evaluate the prevalence of atheroma on the common carotid artery on digital panoramic radiography (DPR) of a Brazilian subpopulation, relating it to age, sex, antimere and to analyze the morphology of its calcification.…”

This study had as a goal to analyze the prevalence of suggestive images of atheromatous calcification in the common carotid artery, aiming to relate it to age, sex, antimere and to analyze the morphology of its calcification, through digital panoramic radiographs of the jaws. It’s an observational, transversal and retrospective study, on which there were analyzed 4.837 radiographs, that came from the files of a dental radiology private service in the city of Cabo de Santo Agostinho-PE, Brazil, referring to the period between 2011-2017. The morphology of the calcified atheromatous plaque was classified in: Grade I – normal (plaque not displayed); Grade II – intimal thickening; Grade III – simple plaque (less than 5mm thick); Grade IV – complex plaque (over 5mm thick) and Grade V – debris (irregular plaque with moving projections). The data collected was expressed in absolute values and frequency, analyzed through the chi-square, considering p< 0,05. Of the analyzed radiographs, 1.321 filled the eligibility criteria, of these 51 (3,8%0 presented suggestive image of atheromatous plaque, 71% were of the female sex (p = 0,003), 45% were at the age range between 5th and 6th decade of life (p= 0,001), most of the identified plaques were unilateral, to the left (p=0,02) and 76% were morphologically classified as grade III (less than 5mm thick). In this study, it was verified the low prevalence of suggestive images of atheromatous in carotid artery, with greater occurrence on the female sex, between the 5th and 6th decade of life, unilaterally, to the left and morphologically classified in grade III
