The article analyzes the death certificates of patients who died at Edmundo Vasconcelos Hospital between January 2016 and June 2019, with a focus on evaluating diabetes mellitus (DM) as a cause of death and its main comorbidities. The results show that DM was underestimated as a cause of death in the death certificates, with a prevalence of 18.5% in the certificates, while the electronic medical records revealed a prevalence of 33.3%. The main complications associated with DM were coronary artery disease, peripheral arterial obstructive disease, and systemic arterial hypertension. The study suggests the inclusion of a new field in death certificates to record the main comorbidities in order to obtain more reliable data. [Extracted from the article]

Background: Diabetics are at 5-15 times greater risk of developing peripheral arterial disease (PAD) and few studies have compared risk factors and distribution and severity of arterial changes in diabetics compared with non-diabetics. Objectives: To compare angiographic changes between diabetic and non-diabetic patients with advanced PAD and correlate them with risk factors. Methods: A retrospective cross-sectional study was conducted of consecutive patients undergoing lower limb arteriography for PAD (Rutherford 3-6) using TASC II and Bollinger et al. angiographic scores. Exclusion criteria were upper limb angiographies, unclear images, incomplete laboratory test results, and previous arterial surgeries. Statistical analyses included chi-square tests, Fisher's test for discrete data, and Student's t test for continuous data (significance level: p < 0.05). Results: We studied 153 patients with a mean age of 67 years, 50.9% female and 58.2% diabetics. A total of 91 patients (59%) had trophic lesions (Rutherford 5 or 6) and 62 (41%) had resting pain or limiting claudication (Rutherford 3 and 4). Among diabetics, 81.7% were hypertensive, 29.4% had never smoked, and 14% had a history of acute myocardial infarction. According to the Bollinger et al. score, infra-popliteal arteries were more affected in diabetics, especially the anterior tibial artery (p = 0.005), while the superficial femoral artery was more affected in non-diabetics (p = 0.008). According to TASC II, the most severe angiographic changes in the femoral-popliteal segment occurred in non-diabetic patients (p = 0.019). Conclusions: The most frequently affected sectors were the infra-popliteal sectors in diabetics and the femoral sector in non-diabetics. [ABSTRACT FROM AUTHOR]

Background: The great saphenous vein is the main superficial vein of the lower limb, and also the most used as arterial graft for lower limb revascularization. Prior knowledge of the quality of the vein can guide the change in the therapeutic strategy, avoiding surgeries that are doomed to failure. The discrepancy between intraoperative findings of the quality of the great saphenous vein and imaging tests was also frequently observed. Objectives: Evaluate the diameter of the great saphenous vein through two imaging methods (Duplex Ultrasound and Computed Tomography) and the gold-standard (intraoperative direct measurement of the vein), comparing the results. Methods: Prospective, observational study, where the data collected were obtained from routine medical procedures performed by the Vascular Surgery team. Results: 41 patients were evaluated, with a 12-month follow-up. 27 (65.85%) were male, with a mean age of 65.37 years. 19 (46.34%) patients underwent femoropopliteal graft and 22 (53.66%) underwent distal grafts. Preoperative saphenous vein internal diameters were on average, with the patient supine, 16.4% smaller on CT and 33.8% smaller on USG than the external diameter after intraoperative hydrostatic dilatation. There was no statistical difference in measurements when sex, weight and height were considered. Conclusions: The assessment of saphenous vein diameter was underestimated by preoperative USG and CT scans when compared to intraoperative measurements. Thus, in patients undergoing graft planning for revascularization, the choice of conduit should take this data into consideration so that there is no unnecessary exclusion of the use of the saphenous vein in planning.

Background: Atherosclerosis risk factors can have different impacts on cardiovascular diseases and on the anatomical distribution of Peripheral Arterial Disease (PAD). Objectives: To study the influence of atherosclerosis risk factors on the anatomical distribution of PAD in patients with chronic limb-threatening ischemia (CLTI). Methods: We performed an observational, cross-sectional, and analytical study that included 476 hospitalized patients with CLTI due to PAD. We compared the presence of atherosclerosis risk factors (age, gender, diabetes mellitus, smoking, and hypertension) in patients with PAD involving three different anatomic areas (aortoiliac, femoropopliteal, and infrapopliteal). Multivariate analysis was performed to identify associations between atherosclerosis risk factors and PAD distribution. Results: The mean age of the 476 patients was 69 years, 249 (52%) were men, and 273 (57%) had diabetes. Seventy-four percent (353) had minor tissue loss. Multivariate analysis identified three risk factors associated with PAD anatomical distribution (gender, smoking, and DM). Women had a 2.7 (CI: 1.75-4.26) times greater chance of having femoropopliteal disease. Smokers had a 3.6-fold (CI: 1.54-8.30) greater risk of aortoiliac disease. Diabetic patients were 1.8 (CI: 1.04-3.19) times more likely to have isolated infrapopliteal occlusive disease. Conclusions: The study showed that gender, DM, and smoking impact on the anatomical distribution of PAD in patients with CLTI. Diabetic patients were more likely to have only infrapopliteal disease, women had a greater risk of femoropopliteal PAD, and smokers had a greater risk of aortoiliac occlusive disease.

Objective: To evaluate the proportion of evidence of neuropathy and peripheral arterial disease, and to identify its relationship with sociodemographic variables, lifestyle and clinical factors with the classification of risk related to the foot of people with Diabetes Mellitus. Methods: Cross-sectional, descriptive, quantitative study. Sample for convenience 60 people in three Basic Health Units. It was used a sociodemographic form, clinical form for the assessment and screening of neuropathic pain, loss of protective sensitivity and peripheral arterial disease in primary care, a questionnaire for evidence of diabetic neuropathy. Pearson's test was applied in the relationship study. Results: Female predominance, mean age 58.1 (± 12.6) years, diagnosis time 12 years (± 9.6) and casual blood glucose 211.3mg/dl (± 91.7). Five participants presented evidence for neuropathy and none presented evidence for peripheral arterial disease. Significant correlation between risk classification, scores for neuropathic impairment (p <0.05) and monofilament (p <0.002). Conclusion: There was a low proportion of neuropathy and peripheral arterial disease, neuropathic impairment score and sensitivity to monofilament, were associated with risk classification. These relationships represent the need for intervention through the practice of screening for complications, which may contribute to the prevention of diabetic foot with amputation.

The diabetic neuropathy is a severe complication resulting from Diabetes Mellitus (DM), which can cause ulcerations in the feet and lead to amputations in the lower limbs (LL). The aim of the present study is to evaluate the feet, self-care and the neuropathy impairment of LL in individuals with Type 2 DM (DM2), as well as to correlate impairment with age, diagnosis time and glycemic control. Socio-demographic and anthropometric data were collected, and fasting blood glucose and glycated hemoglobin (HbA1C) tests were conducted, as well as clinic examination was applied to the feet. Plantar protective sensitivity was assessed, as well as the Neuropathy Impairment Score (NIS), the Neuropathy Symptom Score (NSS) and the Diabetes Self-Management Questionnaire (DSMQ). Results were descriptively shown and the Spearman correlation test was adopted to correlate DM2 diagnosis time with NIS, NSS, age and HbA1C (p<0.05). Sixty-six individuals, at the age group 62 years (56-65) were evaluated. The physical examination showed signs of neuropathic foot and arterial insufficiency. There was change in the plantar protective sensitivity (48.5%), in the neuropathy impairment (48.5%) and in the neuropathy symptoms (59%). The combination between NIS and NSS diagnosed 33% of patients with peripheral diabetic neuropathy. There were weak positive correlation between age and DM2 diagnosis time, age and NIS, HbA1c and NSS, and among DM2 diagnosis time, NIS and NSS. The self-management items concerning the feet presented good adhesion. Conclusion: We found signs of neuropathic foot and insufficient arterial, these predictive factors of future foot ulcerations, weak positive correlation between age and time of diagnosis with neuropathic changes and good adherence to self-care with feet.

Introduction: Peripheral arterial disease is a systemic vascular atherosclerotic disease that results from lumen narrowing causing a decrease in blood flow to the lower limbs. Its diagnosis can be made through noninvasive tests, such as the ankle-arm index. Objective: To evaluate the cases of peripheral arterial disease in the region of Proença-a-Nova by performing the ankle-arm index, taking into account the risk factors. Methodology: 55 individuals were studied, of which 27 individuals (49.1%) were male and 28 (50.9%) female, with ages ranging from 45 to 89 years and average of 64 ± 9.94 years. Results: Regarding risk factors, most do not exercise regularly (69.1%), coinciding with the absence of intermittent claudication (69.1%). The most present risk factor was hypertension (52.7%). Regarding the ankle-arm index, most have values within the normal range and 12 with mild peripheral arterial disease. There were no cases of moderate or severe disease. Conclusion: In this sample there is a higher percentage of cases with mild peripheral arterial disease in individuals who do not engage in regular physical activity, former smokers, diabetics, dyslipidemics and those with cardiovascular disease.

Introduction: Varicose veins are veins that after being submitted to high pressure on the peripheral venous system become dilated, tortuous and elongated. Patients affected will report pain and venous insufficiency signs in the area. The imaging exam commonly used is the Doppler ultrasound, however, when in front of an intraosseous venous drainage anomaly - intraosseous varix, magnetic resonance should be preferred. Objective: Report a case and review the literature about this uncommon lesion. Materials and Methods: We carried out a review of medical records at Hospital América, a photographic record of diagnostic methods, and a review from the literature. Results: A 46-year-old man with constant pain and burning, as well as edema in his left leg and foot for two months. On physical examination, he had edema in his left leg, ankle, and foot, with a slight increase in temperature at the touch, without changing the skin color. Magnetic resonance imaging shows varicosities of the posterior tibial veins with communication through a perforating vein with varicosity of the posterior tibial intraosseous vein - intraosseous varicose vein. Conclusion: This report demonstrates the difficulty of diagnosing intraosseous varices, which, in addition to being a rare lesion, are diagnosed only by magnetic resonance imaging.

Background: Anxiety and depression are highly prevalent neuropsychiatric conditions and are associated with chronic diseases, pain, loss of autonomy, dependence on others to perform routine activities, and loneliness. Depression often has a cause-and-effect relationship with other diseases, such as: acute myocardial infarction (AMI), systemic arterial hypertension (SAH), diabetes mellitus (DM) and peripheral arterial disease (PAD). Objectives: To estimate the frequency of anxiety and depression in patients of both sexes with PAD admitted to a tertiary hospital. Methods: This is a descriptive, cross-sectional study, with a non-random sample selected consecutively. The Hospital Anxiety and Depression Scale (HADS) was used to assess anxiety and depression, and the ankle-brachial index (ABI) was used to assess PAD. Results: The prevalence of anxiety in these patients was 24.4%, with associations between anxiety and monthly family income, smoking, and SAH. The prevalence of depression was 27.6%, with associations between depression and the female gender, being married or in a stable relationship, living on a family income of one minimum wage or less, not being an alcoholic, and having hypertension. Conclusions: There are high prevalence rates of anxiety and depressive disorders among patients with PAD, which are underdiagnosed and, hence, not properly treated. [ABSTRACT FROM AUTHOR]

This article discusses the risk of ulcers and quality of life in diabetic individuals in the Recôncavo Baiano region. The cross-sectional study was conducted with 62 individuals in a basic health unit, collecting sociodemographic and clinical data. The results showed that painful neuropathy, loss of protective sensitivity, and peripheral arterial disease were identified as prevalent risk factors for ulcers. Additionally, participants reported dissatisfaction with dietary flexibility and concerns about the impact of the disease on their families. It is concluded that it is important to provide adequate basic care to improve the quality of life of these diabetic individuals. [Extracted from the article]

INTRODUÇÃO: Apesar da elevada mortalidade dos pacientes em hemodiálise devido às doenças cardiovasculares, é incomum a realização de exames diagnósticos para doença arterial obstrutiva periférica e artérias pouco compressíveis. OBJETIVOS: Analisar a prevalência de doença arterial obstrutiva periférica e artérias pouco compressíveis em hemodialisados, comparando-os com o Grupo Controle. MÉTODOS: Tratou-se de um estudo transversal, com 78 hemodialisados e 88 pacientes que não faziam hemodiálise com, pelo menos, dois fatores de risco para doença arterial obstrutiva periférica (Grupo Controle). Para aferição da pressão arterial sistólica, utilizou-se Doppler vascular portátil e esfigmomanômetro. Esta foi aferida somente nos membros que não possuíam fístula arteriovenosa. O índice tornozelo-braço foi calculado utilizando cada artéria do membro inferior. Foram considerados normais os valores de 0,9 a 1,3. RESULTADOS: Diagnosticou-se doença arterial obstrutiva periférica e artérias pouco compressíveis em 26,9 e 30,8%, dos hemodialisados, e em 33 e 22,7%, do Grupo Controle. Nos hemodialisados, verificou-se o índice tornozelo-braço alterado em 75% dos sintomáticos (p=0,005), em 67,3% dos homens e 31% das mulheres (pINTRODUCTION: Despite the high mortality in hemodialysis patients due to cardiovascular diseases, it is unusual performing diagnostic tests for peripheral arterial disease and poorly compressible arteries. OBJECTIVES: To analyze the prevalence of peripheral arterial disease and poorly compressible arteries in hemodialysis patients, by comparing them to the Control Group. METHODS: It was a cross-sectional study with 78 hemodialysis patients and 88 non-hemodialysis patients with at least two risk factors for peripheral arterial disease (Control Group). To evaluate blood pressure, portable vascular Doppler and sphygmomanometer were used. The pressure was measured from the limb without arteriovenous fistula. The ankle-brachial index was calculated for each artery of the lower limb. It was considered normal ankle-brachial index from 0.9 to 1.3. RESULTS: We diagnosed peripheral arterial disease and poorly compressible arteries in 26.9 and 30.8% of hemodialysis patients and in 33 and 22.7% of the Control Group. In hemodialysis patients, we found abnormal ankle-brachial index in 75% of symptomatic patients (p=0.005), in 67.3% of men and 31% of women (p

A acroangiodermatite ou pseudossarcoma de Kaposi é entidade angioproliferativa incomum relacionada a insuficiência venosa crônica, fístulas arteriovenosas, membros paralisados, cotos de amputação, síndromes vasculares e condições trombóticas. Apresenta-se, em geral, como máculas, pápulas ou placas purpúricas no dorso dos pés (especialmente hálux) e maléolos. Relatamos um caso de acroangiodermatite afetando a região plantar, por dois anos sem diagnóstico, para o qual a coloração histológica por hematoxilina-eosina e a marcação imuno-histoquímica com CD34 foram decisivas. A paciente tinha insuficiência venosa crônica e a lesão respondeu bem ao uso de bandagens elásticas e repouso com a perna elevadaAcroangiodermatitis, often known as pseudo-Kaposi sarcoma, is an uncommon angioproliferative entity related to chronic venous insufficiency, arteriovenous fistulae, paralysed limbs, amputation stumps, vascular syndromes and conditions associated with thrombosis. It presents most frequently as purple macules, papules or plaques in the dorsal aspects of the feet, especially the toes, and the malleoli. We report a case of acroangiodermatitis in the plantar aspect of the foot, misdiagnosed for two years, in which haematoxylin-eosin hystopathological stain and immunolabeling with CD34 histochemistry examination were decisive for diagnosis. Patient had chronic venous insufficiency. The lesion responded well to the treatment with a combination of leg elevation and compression

Os problemas do pé são uma complicação comum da diabetes, com uma prevalência de 23-42% para a neuropatia, 9-23% - para a doença vascular e 5-7% - para a ulceração do pé. Estes, resultam em importantes consequências médicas, sociais e económicas para os doentes, respectiva família e sociedade. A ulceração do pé diabético está associada à doença vascular periférica e neuropatia periférica, frequentemente em combinação. No entanto, os indivíduos com um risco elevado de ulceração podem ser facilmente identificados através de um exame clínico cuidadoso dos seus pés, estando a educação e follow-up periódicos indicados nestes casos. Quando a úlcera do pé é complicada por uma infecção, a combinação pode ser ameaçadora para o membro e até para a vida. A infecção é definida clinicamente, mas as culturas ajudam na identificação dos agentes patogénicos responsáveis. A terapêutica antimicrobiana deve ser guiada pelos resultados das culturas e, embora esta terapêutica possa curar a infecção isoladamente, não cicatriza a úlcera, carecendo de correcção de outros factores (focos de pressão anómala, isquémia do membro) para lograr esta cicatrização.Diabetic foot problems are a common complication of diabetes, with a prevalence of - 23-42% for neuropathy, 9-23% for vascular disease and 5-7% for foot ulceration. It, results in major medical, social and economic consequences for the patients, their families, and society. Diabetic foot ulceration is associated with peripheral vascular disease and peripheral neuropathy, often in combination. Individuals with the greatest risk of ulceration can easily be identified by careful clinical examination of their feet. Education and frequent follow-up is indicated for these patients. When a foot ulcer is complicated by an infection, the combination can be limb-threatening, or life-threatening. Infection is defined clinically, but wound cultures assist in identifying the causative pathogens. Antimicrobial therapy should be guided by culture results.., nevertheless such therapy, by itself, may cure the infection, but it does not heal the wound. To achieve that, it is also necessary to correct the other factors (abnormal pressure points, limb ischemia).

Contexto: Estudos recentes indicam que a concentração elevada de homocisteína é um fator de risco importante e prevalente para doença vascular aterosclerótica coronariana, cerebral e periférica. Objetivo: Tendo em vista a escassez de informações relacionadas à hiper-homocisteinemia em doença arterial periférica (DAP) no Brasil e as peculiaridades de nossa população, o objetivo deste estudo foi avaliar a frequência de hiper-homocisteinemia em amostra dessa população em um ensaio clínico com indivíduos portadores e não portadores de DAP atendidos em um serviço público brasileiro. Métodos: Foi realizado um estudo ensaio clínico caso-controle com 40 indivíduos portadores de DAP confirmada por Doppler ultrassom (grupo DAP) em comparação com 20 indivíduos voluntários sem DAP (grupo-controle). Resultados: A DAP predominante foi a isquemia crônica de membros (75%). As concentrações plasmáticas medianas de homocisteína de jejum foram significantemente maiores no grupo DAP do que no grupo-controle (16,7 versus 12,9 µmol/L, p = 0,001), tanto nos homens (18,9 versus 14,0 µmol/L, p = 0,005) quanto nas mulheres (13,9 versus 11,2 µmol/L, p = 0,025). Quanto à proporção de indivíduos com hiper-homocisteinemia, observou-se tendência a uma maior frequência no grupo DAP (60%) em relação ao grupo-controle (30%) (p = 0,054). Nos indivíduos com idade inferior a 60 anos foram encontrados valores medianos de homocisteína significantemente mais elevados no grupo DAP (p = 0,041). Conclusões: A hiper-homocisteinemia é um fator de risco importante e foi encontrada em 60% dos indivíduos portadores de DAP atendidos em um serviço público no Brasil.Background: Recent studies have suggested that high level of homocysteine is an important and prevalent risk factor for coronary, cerebral and peripheral arterial disease. Objective: In light of the lack of information on hyperhomocysteinemia in peripheral arterial disease (PAD) in Brazil and the peculiarities of its population, the objective of the present study was to evaluate the frequency of hyperhomocysteinemia in a sample of the Brazilian population by means of a clinical trial involving individuals with and without PAD being treated at a public health care facility. Methods: A case-controlled clinical trial was conducted with 40 individuals with a PAD diagnosis confirmed by Doppler ultrasound (PAD group) compared with 20 volunteer individuals without PAD (control group). Results: The predominant PAD was chronic limb ischemia (75%). Median fasting plasma levels of homocysteine were significantly higher in the PAD group than in the control group (16.7 vs. 12.9 μmol/L, p = 0.001), both in men (18.9 vs. 14.0 μmol/L, p = 0.005) and women (13.9 vs. 11.2 μmol/L, p = 0.025). As to the proportion of individuals with hyperhomocysteinemia, a tendency toward a higher frequency was observed in the PAD group (60%) in relation to the control group (30%) (p = 0.054). Individuals aged less than 60 years had significantly high median values of homocysteine in the PAD group (p = 0.041). Conclusions: Hyperhomocysteinemia was a prevalent and important risk factor in individuals with PAD treated at a public health care facility in Brazil.

A maioria dos pacientes portadores de claudicação intermitente, um aspecto clínico da doença arterial periférica, tem importante limitação nas atividades físicas e redução na qualidade de vida. O objetivo deste estudo foi realizar uma revisão da literatura sobre a intervenção através de exercícios em portadores de doença arterial obstrutiva periférica com claudicação intermitente. Trata-se de uma revisão de artigos científicos consultados nos bancos de dados da BIREME, PubMed e SciELO, através das fontes LILACS e MEDLINE e a partir dos descritores em Ciências da Saúde claudicação intermitente, doenças vasculares periféricas, reabilitação, exercício e terapia por exercício. Concluiu-se que, apesar da variabilidade dos regimes de caminhada identificados na literatura, o treino aeróbio, de uma forma geral, proporciona benefícios a pacientes portadores de doença arterial obstrutiva periférica com claudicação intermitente, principalmente na melhora do desempenho de caminhada, o que pode ter impacto significativo na qualidade de vida desses pacientes.Most patients with intermittent claudication, a clinical aspect of peripheral arterial disease, have important limitations on physical activity and a reduced quality of life. The purpose of this study was to review literature on exercise intervention for patients with peripheral occlusive arterial disease and intermittent claudication. BIREME, PubMed (MEDLINE), SciELO and LILACS databases were searched for the terms intermittent claudication, peripheral vascular diseases, rehabilitation, exercise, exercise therapy, all of which were taken from the list of Health Science Descriptors (BIREME). It was concluded that, despite the variability of walking regimens identified in the literature, the aerobic training is of general benefit to patients with peripheral arterial disease and intermittent claudication, mainly improving their walking performance, which can have a significant impact on the quality of life of these patients.

Atualmente, o tratamento das doenças vasculares periféricas é uma das áreas da medicina de maior expansão. O número de intervenções vasculares aumenta e os resultados das novas técnicas endovasculares estão muito próximos aos das tradicionais cirurgias vasculares. Embora a angioplastia ofereça bons resultados em curto prazo, o implante de stents procura melhorar o sucesso do procedimento e estender o seu uso a um número maior de pacientes com doença vascular periférica. Entretanto, a sua utilização ainda é controversa. O implante de stents no sistema aorto-ilíaco tem bons resultados; porém, a sua indicação para as lesões femoro-poplíteas ainda é discutida. Além disso, o rápido desenvolvimento de stents e sua escolha para uso no sistema vascular periférico têm sido uma difícil tarefa para o cirurgião endovascular. Muitos fatores influenciam a escolha do stent, e um amplo conhecimento desse material é essencial. Tal escolha depende da avaliação pré-operatória, da localização e das características da lesão e também do uso do stent primário ou seletivo. Nesse trabalho, são realizadas revisão do histórico do desenvolvimento dos stents, desde os estudos experimentais até os ensaios clínicos e também discussão sobre a sua aplicação no tratamento das doenças vasculares periféricas.The treatment of peripheral vascular diseases is one of the most rapidly expanding fields of medicine today. The number of peripheral interventions increased and innovative endovascular techniques are close to the results of traditional vascular surgeries. Although balloon angioplasty alone offers good immediate results, implantation of stents has been proposed to improve the procedural success and extend its application to more patients with peripheral vascular disease. However, stenting is controversial. Use of stents has good results in aortoiliac vessels, but its use in femoropopliteal vessels is still in dispute. Moreover, the rapid development of endovascular stents for peripheral applications and their choice have been a complicated task for endovascular surgeons. Many factors influence choice of stent, therefore, knowledge of available stents is mandatory. Appropriate selection depends on adequate preprocedural evaluation of the lesion, choice of primary vs. selective stent placement, and location and characteristics of the lesion. In this article the history of stent development is reviewed, from studies with experimental models to clinical practice, and its application in the treatment of peripheral vascular diseases is discussed.

FUNDAMENTO: Índice Tornozelo-Braquial (ITB) é essencial na prática clínica, mas dificuldades técnicas na sua execução pelo padrão de referência Doppler vascular (DV) tornam-no ainda pouco utilizado. OBJETIVO: Avaliar aplicabilidade da determinação do ITB com uso de esfigmomanômetros oscilométricos automáticos (EOA) e sugerir a utilização dos índices delta-Bráquio-Braquial (delta-BB) e delta-ITB como marcadores de risco cardiovascular. MÉTODOS: Estudo descritivo e observacional de 247 pacientes ambulatoriais (56,2% feminino, média 62,0 anos) submetidos à determinação do ITB com aferição simultânea da pressão arterial (PA) em membros superiores (MMSS) e inferiores (MMII) utilizando-se dois EOA (OMRON-HEM705CP). Nos casos em que não foi possível aferir PA em pelo menos um dos MMII utilizou-se DV. Os pacientes divididos em Grupo N (ITB normal: 0,91 a 1,30) e Grupo A (ITB alterado: 1,30) tiveram comparados entre si os valores de delta-ITB (diferença absoluta ITB/MMII) e delta-BB (diferença absoluta PAS/MMSS). RESULTADOS: Utilizando-se EOA foi possível determinar ITB em 90,7%. Com dados do Grupo N determinaram-se valores de referência (VR) no percentil 95 de delta-ITB (0-0,13) e delta-BB (0-8 mmHg). Quando comparado com o Grupo N, o Grupo A apresentou prevalência mais elevada tanto de delta-ITB (30/52 contra 10/195; Razão de Chances: 25,23; pBACKGROUND: Assessing Ankle-Brachial Index is an essential procedure in clinical settings, but since its measurement by the gold standard Doppler Ultrasonic (DU) technique is impaired by technical difficulties, it is underperformed. OBJECTIVE: The aim of this study was to assess the efficacy of an automated oscillometric device (AOD) by performing Ankle-Brachial Index (ABI) assessments and to suggest delta brachial-brachial (delta-BB) and delta-ABI as markers of cardiovascular risk. METHODS: In this observational and descriptive study, 247 patients (56.2% females, mean age 62.0 years) had their arterial blood pressure (ABP) measured for ABI calculation. Two AOD (OMRON-HEM705CP) devices were used for simultaneous measurements of the ABP, first of the two arms and then of the arm with higher systolic ABP and a leg, first the left and then the right one. When leg ABP measurements were not possible, ABI determination was performed by using the standard Doppler Ultrasonic (DU) technique. Patients were designated to Group N (normal ABI: 0.91 to 1.30) or Group A (abnormal ABI: 1.30). Other indexes were also calculated: delta-BB (absolute difference in mmHg of systolic ABP between arms) and delta-ABI (absolute difference of ABI between legs) and the results were compared. RESULTS: In most patients (90.7%), it was possible to determine the ABI. Group N data allowed calculation of the 95th percentile reference values (RV) of delta-BB (0 to 8 mmHg) and delta-ABI (0 to 0.13). When compared to Group N, Group A had a significantly higher prevalence of high values greater than the RVs of delta-ABI (30 of 52 and 10 of 195, respectively; Odds Ratio = 25.23; p

Patologias vasculares periféricas freqüentemente acometem idosos e, sendo crônicas, interferem na qualidade de vida desses indivíduos, inclusive no sono. Portanto, este estudo objetivou avaliar a qualidade do sono de idosos com patologias vasculares periféricas em acompanhamento ambulatorial no Hospital das Clínicas da Universidade Estadual de Campinas. Os voluntários (n=50, idade média de 74 8 anos) responderam ao Índice de Qualidade de Sono de Pittsburgh (PSQI), forneceram dados sociodemográficos e sobre a vasculopatia (35 idosos apresentavam obstrução arterial em membros inferiores). Verificou-se que 34 idosos apresentavam sono de má qualidade. A duração do sono era de 5,8 ( 2,3) horas e, segundo 23 idosos, as dores perturbavam o sono noturno freqüentemente (três vezes na semana ou mais). Somente 18 idosos usavam analgésicos e quatro, medicamentos para dormir. Os achados podem subsidiar o enfermeiro na implementação de medidas para melhorar esse quadro e promover a qualidade de vida das pessoas acometidas.Las patologías vasculares periféricas frecuentemente acometen a las personas de la tercera edad y, siendo crónicas, interfieren en la calidad de vida de esos individuos, inclusive en el sueño. Por tanto, en este estudio se tuvo por objetivo evaluar la calidad del sueño de personas de la tercera edad con patologías vasculares periféricas en tratamiento ambulatorio en el Hospital de las Clínicas de la Universidad Estatal de Campinas. Los voluntarios (n=50, edad media de 74 8 años) respondieron al Índice de Calidad de Sueño de Pittsburgh (PSQI), proporcionaron sus datos sociodemográficos y sobre la vasculopatía (35 personas de la tercera edad presentaban obstrucción arterial en miembros inferiores). Se verificó que 34 personas de la tercera edad presentaban sueño de mala calidad. La duración del sueño era de 5,8 ( 2,3) horas y, según 23 de los participantes, los dolores perturbaban su sueño nocturno frecuentemente (tres veces en la semana o más). Sólo 18 de ellos usaban analgésicos y cuatro, medicamentos para dormir. Los hallazgos pueden ayudar al enfermero en la implementación de medidas para mejorar ese cuadro y promover la calidad de vida de las personas acometidas.Peripheral vascular diseases (PVD) are prevalent among the elderly, and, due to their chronic character, result in poor quality of life and poor sleep quality. This study aimed at evaluating sleep quality of elderly people diagnosed with PVD who undergo clinical ambulatory treatment in a university hospital in Campinas, in the State of São Paulo. Subjects (n=50, aged 74 8 years old) answered the Pittsburgh Sleep Quality Index (PSQI) and provided basic demographic data and PVD history (35 subjects had arterial blockage in lower limbs). Results showed that 34 subjects presented bad sleep quality; sleep length was 5.8 ( 2.3) hours, and, according to 23 subjects, night sleep was frequently disturbed by pain (thrice a week or more). Eighteen subjects took analgesics; four took sleep medicines. Findings may have important implications for nurses working with PVD patients, stressing the need to take into account consequences of PVD on sleep disturbances when planning their interventions.

Sports-related vascular insufficiency affecting the lower limbs is uncommon, and early signs and symptoms can. be confused with musculoskeletal injuries. This is also the case among professional cyclists, who are always at the threshold between endurance and excess training. The aim of this review was to analyze the occurrence of vascular disorders in the lower limbs of cyclists and to discuss possible etiologies. Eighty-five texts, including papers and books, published from 1950 to 2012, were used. According to the literature reviewed, some cyclists receive a late diagnosis of vascular dysfunction due to a lack of familiarity of the medical team with this type of dysfunction. Data revealed that a reduced blood flow in the external iliac artery, especially on the left, is much more common than in the femoral and popliteal arteries, and that vascular impairment is responsible for the occurrence of early fatigue and reduced performance in cycling.

Introduction: Despite the high mortality in hemodialysis patients due to cardiovascular diseases, it is unusual performing diagnostic tests for peripheral arterial disease and poorly compressible arteries. Objectives: To analyze the prevalence of peripheral arterial disease and poorly compressible arteries in hemodialysis patients, by comparing them to the Control Group. Methods: It was a cross-sectional study with 78 hemodialysis patients and 88 non-hemodialysis patients with at least two risk factors for peripheral arterial disease (Control Group). To evaluate blood pressure, portable vascular Doppler and sphygmomanometer were used. The pressure was measured from the limb without arteriovenous fistula. The ankle-brachial index was calculated for each artery of the lower limb. It was considered normal ankle-brachial index from 0.9 to 13. Results: We diagnosed peripheral arterial disease and poorly compressible arteries in 26.9 and 30.8% of hemodialysis patients and in 33 and 22.7% of the Control Group. In hemodialysis patients, we found abnormal ankle-brachial index in 75% of symptomatic patients (p=0.005) in 67.3% of men and 31% of women (p<0.005), in 78.6% of the elderly, 34.8% of young adults (p<0.01), and 76.9% of diabetics (p<0.005) versus nondiabetic). These patients had a higher prevalence of severe peripheral arterial disease than the Control Group. Conclusions: Abnormal ankle-brachial index was very prevalent in the groups studied; however, hemodialysis patients had more severe changes, when compared to the Control Group. Diabetes mellitus, male gender, and advanced age were important risk factors for abnormal ankle-brachial index in hemodialysis patients. The ankle-brachial index was a good method of screening for the studied changes; therefore, we suggest the routine use in the management of hemodialysis patients. [ABSTRACT FROM AUTHOR]

Background: Recent studies have suggested that high level of homocysteine is an important and prevalent risk factor for coronary, cerebral and peripheral arterial disease. Objective: In light of the lack of information on hyperhomocysteinemia in peripheral arterial disease (PAD) in Brazil and the peculiarities of its population, the objective of the present study was to evaluate the frequency of hyperhomocysteinemia in a sample of the Brazilian population by means of a clinical trial involving individuals with and without PAD being treated at a public health care facility. Methods: A case-controlled clinical trial was conducted with 40 individuals with a PAD diagnosis confirmed by Doppler ultrasound (PAD group) compared with 20 volunteer individuals without PAD (control group). Results: The predominant PAD was chronic limb ischemia (75%). Median fasting plasma levels of homocysteine were significantly higher in the PAD group than in the control group (16.7 vs. 12.9 ⩽mol/L, p = 0.001), both in men (18.9 vs. 14.0 ⩽mol/L, p = 0.005) and women (13.9 vs. 11.2 ⩽mol/L, p = 0.025). As to the proportion of individuals with hyperhomocysteinemia, a tendency toward a higher frequency was observed in the PAD group (60%) in relation to the control group (30%) (p = 0.054). Individuals aged less than 60 years had significantly high median values of homocysteine in the PAD group (p = 0.041). Conclusions: Hyperhomocysteinemia was a prevalent and important risk factor in individuals with PAD treated at a public health care facility in Brazil. [ABSTRACT FROM AUTHOR]

Most patients with intermittent claudication, a clinical aspect of peripheral arterial disease, have important limitations on physical activity and a reduced quality of life. The purpose of this study was to review literature on exercise intervention for patients with peripheral occlusive arterial disease and intermittent claudication. BIREME, PubMed (MEDLINE), SciELO and LILACS databases were searched for the terms intermittent claudication, peripheral vascular diseases, rehabilitation, exercise, exercise therapy, all of which were taken from the list of Health Science Descriptors (BIREME). It was concluded that, despite the variability of walking regimens identified in the literature, the aerobic training is of general benefit to patients with peripheral arterial disease and intermittent claudication, mainly improving their walking performance, which can have a significant impact on the quality of life of these patients.

Ineffective peripheral tissue perfusion is a nursing diagnosis of NANDA; whose definition means a reduction in blood circulation to the periphery that may compromise health. Such diagnosis is associated with diabetes mellitus and hypertension. Peripheral arterial obstructive disease (PAD) is characterized by the stiffening of the artery wall and the narrowing of its light, commonly occurring in the lower limbs, causing a chronic atherosclerotic process. Based on the literature, there is a strong association between the clinical manifestation of PAD and a picture of diabetes mellitus (DM) and systemic arterial hypertension (SAH), given the systemic characteristics of both. In this way, the present study aimed to review the nursing guidelines based on evidence that will help the intensive care nurse in the identification of nursing care diagnoses and prescriptions to achieve the tissue perfusion: peripheral result. The descriptive research was carried out through a systematic literature review and based on secondary works published from 2011 to 2018. [ABSTRACT FROM AUTHOR]

Objective: to compare two compression times of the radial artery after coronary angiography with customized compressive dressing regarding the occurrence of hemostasis and vascular complications., Method: a randomized clinical study was carried out in patients undergoing elective transradial coronary angiography in two study groups: (G30), whose compressive dressing was maintained for 30 minutes, and (G60), whose compressive dressing was maintained for 60 minutes, both until the first evaluation of hemostasis. Variables related to patients, procedure, occurrence of hemostasis, and vascular complications were analyzed. Patency of the radial artery was assessed with Doppler vascular ultrasonography, immediately after removing the compressive dressing and 30 days after the procedure., Results: the sample consisted of 152 patients in G30 and 151 in G60. Hemostasis was evidenced in the first evaluation in 76.3% of G30 patients and 84.2% of G60 patients (p = 0.063). There were 91 immediate complications, being 53 hematomas and 38 occlusions of the radial artery. We identified 18 late occlusions, 7 (5.5%) in G30 and 11 (8.2%) in G60., Conclusion: the different compression times of the radial artery after coronary angiography did not significantly influence the occurrence of hemostasis and vascular complications.
