Profundaplastia femoral como un proceder inusual en la "era endovascular" / Femoral deep plasty as an unfrequent procedure in the "endovascular era"

Introducción: La arteria femoral común y sus ramas suministran la mayor parte del flujo sanguíneo al muslo, así como a la totalidad de la pierna y el pie, lo que da lugar a la mayor rama del triángulo femoral: la arteria femoral profunda. Objetivo: Exponer la efectividad de la profundaplastia femoral en la "era endovascular". Reporte del caso: Se presenta un caso de enfermedad arterial periférica de múltiples sectores, sin criterio de cirugía revascularizadora (derivación protésica aorto bifemoral). El paciente manifestaba claudicación intermitente a menos de 30 metros, localizada en pantorrilla derecha. En el estudio hemodinámico se apreciaron los índices de presiones tobillo/brazo disminuidos en arteria tibial posterior (0,46) y pedia derecha (0,33). La ecografía doppler del sector femoral derecho evidenció una estenosis de la arteria femoral profunda en su origen, que producía aumento de las velocidades picos sistólicos (479 cm/s), con flujo desorganizado, dilatación posestenótica y oclusión de la arteria femoral superficial en su origen. Se realizó endarterectomía femoral común y profunda con colocación de parche de politetrafloroetileno. El paciente evolucionó sin complicaciones posoperatorias. En el seguimiento se observó mejoría clínica en relación con la distancia de claudicación y un aumento de los índices de presiones tobillo/brazo en arteria tibial posterior y pedia derecha (0,50), respectivamente. Conclusiones: La profundaplastia femoral, aún en la "era endovascular", permanece como un proceder eficaz que resulta alternativa de tratamiento revascularizador en la enfermedad arterial periférica de localización infrainguinal(AU)

Introduction: The normal femoral artery and its branches supply most of the blood flow to the thigh, as well as to the whole leg and foot, which forms the largest branch of the femoral triangle: the deep femoral artery. Objective: Show the effectiveness of femoral deep plasty in the "endovascular era". Case report: It is presented a case of peripheral artery disease in multiple sectors, without surgical criteria of revascularization (derivación protésica aortobifemoral). The patient presented intermittent claudication in less than 30 meters, and it was located in the right calf. In the hemodynamic study, the ankle-arm pressure indexes were dicreased in the posterior tibial artery (0,46) and right dorsalis pedis artery (0,33). The doppler echocardiography of the right femoral sector confirmed a stenosis in the deep femoral artery in its origin, which produced an increase in the peak systolic velocity (479 cm/s), unorganized flows, poststenotic dilatation and occlusion of the superficial femoral artery in its origin. It was performed a common and deep femoral endarterectomy with colocation of polytetrafluoroethylene patch. The patient evolved without post-surgical complications. In the follow-up, it was observed a clinical improvement in relation with the claudication distance and the increase of the ankle-arm pressure indexes in the posterior tibial artery and right dorsalis pedis artery (0,50), respectively. Conclusions: The femoral deep plasty, still in the ´´endovascular era´´, is an efficient procedure that is an alternative to the revascularization treatment in the peripheral artery disease with infrainguinal location(AU)

Caracterización de los pacientes con enfermedad arterial periférica, tratados con células mononucleares autólogas / Characterization of patients with peripheral arterial disease treated with autologous mononuclear cells

Introducción: La enfermedad arterial oclusiva de miembros inferiores se asocia con un alto índice de amputaciones y riesgo de muerte. Al respecto, la medicina regenerativa ha mostrado resultados satisfactorios. Objetivo: Caracterizar a los pacientes con enfermedad arterial periférica de los miembros inferiores, tratados con células mononucleares autólogas. Métodos: Se realizó una investigación longitudinal prospectiva en el Hospital Universitario "Arnaldo Milián Castro", durante el período desde enero de 2015 hasta diciembre de 2017. De una población de 61 pacientes se seleccionó una muestra de 52 de forma intencional por criterios. Resultados: La edad promedio resultó de 66,9 ± 8,2 años y el 69,2 por ciento representó al sexo masculino. Los principales factores de riesgo vascular fueron el tabaquismo, la hipercolesteronemia y la hipertensión arterial. El nivel de oclusión mostró predominio fémoro poplíteo y el tractus de salida malo constituyó la principal causa de no revascularización. La viabilidad celular fue elevada y se logró cambio significativo en los estadios de Fontaine. El inicio de la mejoría clínica ocurrió entre el primer y el segundo mes en la mayoría de los casos. En una parte de los pacientes se abrieron posibilidades posquirúrgicas y se obtuvo muy buena reperfusión tisular. Conclusiones: El implante de células mononucleares autólogas en pacientes con enfermedad arterial periférica de los miembros inferiores constituye una nueva estrategia de angiogénesis terapéutica muy útil y efectiva, que abre nuevas perspectivas de tratamiento(AU)

Introduction: Low limbs´ arterial occlusive disease is associated with a high rate of amputations and risk of death. Regarding that, regenerative medicine has proven satisfactory results. Objective: To characterize patients with peripheral arterial disease in the low limbs which have been treated with autologous mononuclear cells. Methods: It was carried out a prospective longitudinal research in "Arnaldo Milián Castro" Hospital in the period from January, 2015 to December, 2017. From a population of 61 patients, it was intentionally selected by criteria a sample of 52 individuals. Results: The average age was 66,9 ± 8,2 and 69,2 percent were men. The main vascular risk factors were smoking habit, hypercholesterolemia and arterial hypertension. The level of occlusion showed predominance of femoro-popliteal and the bad output tractus was the main cause of non-revascularization. Cell viability was high and it was achieved a significant change in Fontaine stages. The beginning of a clinical improvement happened between the first and the second month in most of the cases. In some patients were open post-surgical possibilities and it was obtained great tisular reperfusion. Conclusions: The implant of autologous mononuclear cells in patients with peripheral arterial disease of low limbs represents an useful and effective new strategy of therapeutic angiogenesis which opens new treatment perspectives(AU)

Vitamin D serum levels and peripheral arterial disease among southern Brazilian adults

SUMMARY OBJECTIVE To investigate the association between low serum vitamin D levels and peripheral arterial disease (PAD). METHODS A cross-sectional study with a consecutive sample of 133 individuals from Caxias do Sul, Brasil. We considered PAD patients those with an ankle-brachial index (ABI) ≤ 0.90 or with arterial revascularization. Vitamin D serum level was categorized as sufficient (≥30 ng/mL), insufficient (>20 to 29 ng/mL), and deficient (<20 ng/mL). Prevalence ratios (RP) were calculated through Poisson regression. RESULTS The prevalence of PAD was 50.7% (95% CI 42-59). After adjustment for potential PAD risk factors, RP were 1.08 (95% CI 0.66-1.76) for insufficient serum level and 1.57 (95% CI 0.96-2.57) for deficient vitamin D serum level; (p for trend = 0.020). CONCLUSION Vitamin D serum levels showed an inverse and significant dose-response relationship with PAD.

RESUMO OBJETIVO Investigar a associação entre níveis séricos de vitamina D e doença arterial obstrutiva periférica (DAOP). MÉTODOS Estudo transversal, com amostra consecutiva de 133 indivíduos. Foram considerados com DAOP pacientes com índice tornozelo braquial ≤ 0,90 ou com revascularização arterial. O nível sérico de vitamina D foi classificado em: suficiente (≥30 ng/mL), insuficiente (>20 a 29 ng/mL) e deficiente (<20 ng/mL). Razões de Prevalência (RP) foram calculadas por meio de regressão de Poisson. RESULTADOS A prevalência de DAOP foi de 50,7% (IC95% 42-59). Após ajuste para potenciais fatores de risco para DAOP, as RP foram de 1,08 (IC95% 0,66-1,76) para nível sérico insuficiente e de 1,57 (IC95% 0,96-2,57) para o nível sérico deficiente de vitamina D; (p para tendência = 0,020). CONCLUSÃO O nível sérico de vitamina D mostrou uma relação dose/resposta inversa e significativa com DAOP.

Introdução: Pacientes portadores de vasculopatia periférica internam recorrentemente para procedimentos cirúrgicos ou tratamento clínico devido a complicações da doença de base. O real impacto da desnutrição nesses pacientes durante a internação ainda é pouco compreendido. Objetivo: Investigar os fatores de risco associados à mortalidade em pacientes internados com doença vascular periférica devido a complicação da doença vascular. Métodos: Estudo observacional retrospectivo avaliou cento e dezessete pacientes acima de 18 anos admitidos no serviço de cirurgia vascular de hospital terciário no período de junho de 2013 a agosto de 2014 por complicação da doença vascular. Avaliados parâmetros clínicos, comorbidades, dados demográficos, complicações durante a internação e estado nutricional. Dados coletados por meio de entrevista, aplicação do questionário Avaliação Global Subjetiva (AGS), exame físico e laboratoriais e dados de prontuário. Resultados: Cento e dezessete pacientes com doença vascular periférica avaliados em relação a complicações vasculares durante internação. Mortalidade geral de 7,7% e pacientes desnutridos ou com suspeita de desnutrição eram 39% da amostra Através da análise multivariada, tanto a classificação AGS (OR 6,15 CI 1,092-34,74 P = 0,039) quanto a presença de doença cardíaca (OR 8,51 CI 1,56-47,44 P = 0,015) foram fatores preditores independentes para mortalidade. Pacientes com doença vascular classificados em suspeita de estarem desnutridos ou desnutridos apresentaram chance de ir a óbito durante a internação aumentada em 6,15 vezes, enquanto a cardiopatia elevou essa chance 8,51 vezes. Conclusão: Pacientes internados por complicação de doença vascular periférica apresentam como fatores de risco para mortalidade a desnutrição e a presença de doença cardíaca.(AU)

Patients with peripheral vasculopathy are routinely hospitalized for surgical procedures or clinical treatment due to complications of the underlying disease. The real impact of malnutrition in these patients during hospitalization is still poorly understood. Aim: This study aimed to assess mortality predictors in patients with peripheral vascular disease during hospitalization. Methods: This retrospective observational study evaluate one hundred and seventeen patients over 18 years admitted to the vascular surgery service of a tertiary hospital in the period of June 2013 and August 2014 due to complications of vascular disease. They were assessed for clinical parameters, comorbidities, demographics, complications during hospitalization and nutritional status. Data were collected through interviews, the questionnaire Subjective Global Nutritional Assessment (SGA), laboratory exam and physical examination. Results: One hundred and seventeen patients with peripheral vascular disease were followed during admission due to vascular complications. Overall mortality was 7.7%, and malnourished patients or patients at nutritional risk were 39,0% of the sampled population By multivariate analysis both rating by SGA (OR 6.15, CI 1.092 to 34.74, P = 0.039), the presence of heart disease (OR 8.51 CI 1,56 to 47.44 P = 0.015) were independent predictors of mortality. When the patient was classified as malnourished or suspected of being malnourished by SGA it increased 6.15 times the odds of death during hospitalization, while the presence of heart disease increased by 8.51 times. Conclusion: Patients hospitalized for complications of peripheral vascular disease present as risk factors for mortality: malnutrition and the presence of heart disease. (AU)

Prevalence of peripheral arterial disease in patients with heart failure with preserved ejection fraction

OBJECTIVES: To describe the prevalence of the reduced ankle-brachial index (ABI) in patients with heart failure (HF) with preserved ejection fraction (HFpEF) attended at a HF clinic in the metropolitan region of Porto Alegre, and to compar the patients to those with reduced ejection fraction (HFrEF). METHODS: A descriptive observational study, included patients referred to the heart failure clinic in HU-Ulbra with HFpEF or HFrEF and diastolic dysfunction, and measurements of ABIs using vascular Doppler equipment were performed in both groups. RESULTS: The sample consisted of 106 patients with HF, 53.9% of the patients had HFpEF, and 19.4% had a diagnosis of peripheral arterial disease (PAD) (ABI less than 0.9). PAD was identified in 24.1% of the patients with HFpEF, while15.8% of patients in the HFrEF group were diagnosed with PAD. CONCLUSION: Our results did not identify a significantly different prevalence of altered and compatible PAD values in patients with HFpEF. However, we showed a prevalence of 19.4%, a high value if we consider similar populations.

The best performances were in spacial orientation (92,2% performed as expected) and verbal memory (87,5% performed as expected). Conclusion: The cognitive profile of these patients revealed alterations in most of the assessed cognitive functions, especially in functions directly related to functionalities of the patient.

Ankle-brachial index and diabetic neuropathy: study of 225 patients / Index tornozelo-braquial e neuropatia diabética: estudo de 225 pacientes

ABSTRACT Objective To evaluate neuropathic pain and peripheral vascular disease in diabetics and compare this with the length of time since diagnosis in type 1, and type 2 diabetes. Methods A cross-sectional study with 225 diabetics chosen from their responses on the DN4 questionnaire, who were then evaluated with the ankle-brachial index (ABI), separating type 1 diabetes from type 2 diabetes. Results A higher incidence of neuropathic pain in those over 60 years of age showed an ABI > 1.3. Neuropathic pain was related to an abnormal ABI in 144 patients (64.2%). A statistically significant value was obtained in type 2 diabetes patients with more than 10 years from disease onset, 69 with altered ABI and 25 with normal ABI. There was an altered ABI (< 0.9) observed in 33% of type 1 diabetes patients and in 67% of type 2 diabetes patients. Conclusion The ABI test in type 1 diabetes and type 2 diabetes patients is important even in those who are asymptomatic. A diagnosis of more than 10 years prior, regardless of the presence of neuropathic pain or ischemic signs, altered the ABI.

Conclusão O teste ITB é útil em pacientes com DM 1 e DM 2 quando a dor neuropática é suspeita, mesmo em assintomáticos. E o tempo prolongado de diabetes (> 10 anos), independentemente da presença de dor ou sinais isquêmicos, alterou o ITB.

Implante de células madre hematopoyéticas en pacientes con isquemia crónica de los miembros inferiores / Hematopoietic stem cells implantation in patients with chronic ischemia of lower limbs

Introducción: la enfermedad arterial periférica de los miembros inferiores es un síndrome común que afecta a un elevado porcentaje de la población adulta mundial, asociada con la disminución de la capacidad funcional. Objetivo: determinar el comportamiento del implante de células madre hematopoyéticas en pacientes con isquemia crónica de miembros inferiores. Métodos: se realizó un estudio prospectivo de tipo cuasi-experimental en 159 pacientes con isquemia crónica de los miembros inferiores, mayores de 40 años, atendidos en el Servicio de Angiología del Hospital "Arnaldo Milián Castro" a los que se le realizó un implante de células madre hematopoyéticas. Las variables estudiadas fueron: edad, sexo, factores de riesgo, dolor en reposo, tiempo de marcha libre de dolor, mejoría de las lesiones isquémicas, si hubo amputación mayor después del trasplante, reaparición de manifestaciones isquémicas severas. Los criterios de evaluación del tratamiento fueron: respuesta primaria (cuatro semanas) y avanzada (24 semanas), recaída y fracaso terapéutico. Resultados: la sintomatología más frecuente antes de la implantación fue la claudicación arterial intermitente a menos de 200 metros (IIb) y las lesiones isquémicas (IV), después de la implantación se observó en la mayoría de los pacientes un aumento en la distancia de claudicación arterial intermitente a más de 200 metros (IIa). Solo en 13 pacientes hubo un fracaso terapéutico al requerir de una amputación mayor. Conclusiones: el implante de células madre hematopoyéticas en pacientes con isquemia crónica de miembros inferiores es una buena alternativa terapéutica para el tratamiento de la enfermedad arterial periférica y la disminución del índice de amputaciones(AU)

Introduction: the peripheral arterial disease of lower limbs is a common syndrome that affects a high percentage of world adult population and is associated to a decrease of the functional capacity. Objective: to determine the behavior of hematopoietic stem cells implantation in patients with chronic leg ischemia. Methods: a quasi-experimental prospective study was conducted in a sample of 159 patients aged over 40 years, who suffered from chronic leg ischemia. All of them had been treated at the angiology service of "Arnaldo Milián Castro" hospital and had undergone hematopoietic stem cells implantation. The study variables were age, sex, risk factors, pain at rest, pain-free time of walking, improvement of ischemic lesions, post-transplant major amputation and reoccurrence of severe ischemic manifestations. The evaluation criteria of the treatment were primary response (four weeks) and advanced (24 weeks), relapse and therapeutic failure Results: the most frequent symptoms before the implantation was the intermittent arterial claudication in less than 200 meter distance (IIb) and ischemic lesions (IV). After the implantation, an increase in the distance of intermittent arterial claudication was observed in more than 200 meter (IIa) distance. Therapeutic failure was just observed in patients who required a major amputation. Conclusions: the hematopoietic stem cells implantation in patients with chronic leg ischemia proved to be a good therapeutic alternative for the treatment of peripheral arterial disease, thus reducing index of amputations(AU)

Association of Peripheral Arterial and Cardiovascular Diseases in Familial Hypercholesterolemia / Associação das Doenças Arterial Periférica e Cardiovascular na Hipercolesterolemia Familiar

Background: Familial hypercholesterolemia (FH) is an autosomal dominant genetic disease characterized by an elevation in the serum levels of total cholesterol and of low-density lipoproteins (LDL- c). Known to be closely related to the atherosclerotic process, FH can determine the development of early obstructive lesions in different arterial beds. In this context, FH has also been proposed to be a risk factor for peripheral arterial disease (PAD). Objective: This observational cross-sectional study assessed the association of PAD with other manifestations of cardiovascular disease (CVD), such as coronary artery and cerebrovascular disease, in patients with heterozygous FH. Methods: The diagnosis of PAD was established by ankle-brachial index (ABI) values ≤ 0.90. This study assessed 202 patients (35% of men) with heterozygous FH (90.6% with LDL receptor mutations), mean age of 51 ± 14 years and total cholesterol levels of 342 ± 86 mg /dL. Results: The prevalences of PAD and previous CVD were 17% and 28.2 %, respectively. On multivariate analysis, an independent association between CVD and the diagnosis of PAD was observed (OR = 2.50; 95% CI: 1.004 - 6.230; p = 0.049). Conclusion: Systematic screening for PAD by use of ABI is feasible to assess patients with FH, and it might indicate an increased risk for CVD. However, further studies are required to determine the role of ABI as a tool to assess the cardiovascular risk of those patients. .

Fundamento: A hipercolesterolemia familiar (HF) é uma doença de herança genética autossômica dominante caracterizada pela elevação dos valores séricos de colesterol total e das lipoproteínas de baixa densidade (LDL-c). Conhecida por estar estreitamente relacionada ao processo aterosclerótico, a HF pode determinar o desenvolvimento de lesões obstrutivas precoces em distintos leitos arteriais. Nesse contexto, a HF também tem sido proposta como fator de risco para a doença arterial periférica (DAP). Objetivo: Avaliamos, por meio de um estudo transversal e observacional, a associação da DAP com outras manifestações de doença cardiovascular (DCV), isto é, doença arterial coronária e cerebrovascular em portadores de HF heterozigótica. Métodos: diagnóstico de DAP foi estabelecido pela medida do índice tornozelo-braquial (ITB) com valores ≤ 0,90. Foram estudados 202 pacientes com HF (90,6% apresentando mutações no receptor da LDL), idade 51 ± 14 anos, colesterol total 342 ± 86 mg/dL e 35% do sexo masculino. Resultados: As prevalências de DAP e de DCV prévia foram 17% e 28,2%, respectivamente. Houve associação independente da DAP com a DCV (OR = 2,50, IC 95% 1,004-6,230, p = 0,049) após análise multivariada. Conclusão: A pesquisa sistemática da DAP por meio do ITB é factível na avaliação de portadores de HF e pode sinalizar aumento no risco de DCV. Contudo, mais estudos são necessários para determinar o papel do uso do ITB como ferramenta para avaliação do risco cardiovascular nessa população. (Arq Bras Cardiol. 2014; 103(2):118-123) .

Estudo dos Fatores de Risco Associados a Arteriopatia Periferica em Nipo-brasileiros de Bauru (SP) / Study of Risk Factors Associated with Peripheral Arteriopathy in Japanese-Brazilians from Bauru (SP)

Fundamento: As patologias cardiovasculares são a maior causa de morbimortalidade nos países desenvolvidos e emergentes. Sua principal etiologia, a aterosclerose, é doença disseminada acometendo os territórios coronariano, cerebral e periférico. A doença arterial obstrutiva periférica (DAOP), além de suas consequências per se, sinaliza o acometimento do território coronariano. Portanto, seu melhor conhecimento permite tratamento adequado, retardando complicações locais e à distância, diminuindo o custo para o sistema de saúde. Objetivo: Este estudo estima a porcentagem de DAOP em nipo-brasileiros de Bauru (SP), reconhecidos pela alta prevalência de distúrbios metabólicos, como hipertensão arterial (43%), diabetes melito (33%) e hipercolesterolemia (60 %), e analisa a associação com biomarcadores de risco. Métodos: Este estudo transversal populacional avaliou 1.330 nipo-brasileiros de ambos os sexos com idade ≥ 30 anos que foram submetidos a exame físico completo, medidas antropométricas, exames laboratoriais e índice tornozelo-braço (ITB). Participantes com ITB ≤ 0,90 foram diagnosticados como portadores de DAOP. Após aplicação dos critérios de exclusão, 1.038 indivíduos integraram a análise. Empregou-se regressão de Poisson para análise das associações com DAOP. Resultados: A idade média foi 56,8 anos e a porcentagem de DAOP foi 21,1%, igual entre os sexos. DAOP associou-se com tabagismo (RP 2,16 [1,33-3,48]) e hipertensão arterial (RP 1,56 [1,12-2,22]). Conclusão: A porcentagem de DAOP nos nipo-brasileiros foi semelhante à de outras populações de perfil cardiometabólico desfavorável (US PARTNERS e POPADAD). A associação independente de DAOP com tabagismo e hipertensão, ...

Background: Cardiovascular diseases are the major cause of morbidity and mortality in developed and emerging countries. Their main etiology, atherosclerosis, is a disseminated disease that affects the coronary, cerebral and peripheral territories. The peripheral arterial disease (PAD), as well as its consequences, indicates the involvement of the coronary territory. Therefore, its better understanding enables proper treatment, delaying local and long-term complications, reducing the cost to the health system. Objective: This study estimates the percentage of PAD in Japanese-Brazilians from Bauru (SP), recognized by the high prevalence of metabolic disorders such as hypertension (43%), diabetes mellitus (33%) and hypercholesterolemia (60%), and examines the association with risk biomarkers. Methods: This cross-sectional population study evaluated 1,330 Japanese-Brazilians of both genders aged ≥ 30 who underwent a complete physical examination, anthropometric measurements, laboratory tests and ankle-brachial index (ABI). Participants with ABI ≤ 0.90 were diagnosed as having PAD. After applying the exclusion criteria, 1,038 individuals were part of the analysis. We used Poisson regression to analyze associations with PAD. Results: The mean age was 56.8 years and the percentage of PAD was 21.1%, equal among the genders. PAD was associated with smoking (PR 2.16 [1.33 to 3.48]) and hypertension (PR 1.56 [1.12-2.22]). Conclusion: The percentage of PAD in Japanese-Brazilians was similar to other populations of adverse cardiometabolic profile (US PARTNERS and POPADAD). The independent association of PAD with smoking and hypertension, but not with other classical risk factors, may depend on the very high frequencies of metabolic disorders in this population. .

Análise das arteriografias de diabéticos e não diabéticos com isquemia crítica da perna / Arteriographic findings in diabetic and non-diabetic with critical limb ischemia

RESUMO OBJETIVO: Comparar características angiográficas de pacientes diabéticos e não diabéticos com isquemia crítica. MÉTODOS: Foram incluídos 161 membros inferiores de pacientes com isquemia crítica infrainguinal. Avaliaram-se as características clínicas e arteriográficas (número e presença de opacificação das artérias da perna) dos dois grupos de pacientes. A análise estatística foi realizada pelo EPI-INFO RESULTADOS: A maioria dos pacientes era categoria 5da Classificação de Rutherford e apresentava doença do território fêmoro-poplíteo. Opacificação da artéria fibular foi encontrada em 72% dos não diabéticos e em 67% dos diabéticos (p = 0,25), sendo esta a artéria mais presente em ambos os grupos. Os diabéticos apresentaram menor índice de opacificação da artéria tibial posterior na análise univariada (29% vs. 47%; p = 0,008). Na regressão logística, apenas o sexo feminino se mostrou significante para a ausência da artéria tibial posterior (OR = 2,6; p = 0,01) CONCLUSÃO: A artéria fibular foi a mais encontrada nas angiografias de diabéticos e não diabéticos com isquemia crítica. Diabéticos e não diabéticos não diferiram em relação ao padrão angiográfico da perna.

OBJECTIVE: To compare angiographic findings of diabetic and non-diabetic patients with critical limb ischemia. METHODS: We included 161 patients with infrainguinal critical limb ischemia (CLI). We evaluated the clinical and arteriographic (number and presence of opacification of leg arteries) of the two groups of patients. Statistical analysis was performed using EPI-INFO. RESULTS: Most patientswere category 5 of Rutherford's Classification and had femoropopliteal disease. Seventy-two percent of non-diabetic and 67% of diabetic had opacification of the fibular artery (p = 0.25), this is the most present artery in both groups. Diabetic patients had less opacification of the posterior tibial artery in the univariate analysis (29% vs. 47%, p = 0.008). But only female sex showed a significant risk for the absence of the posterior tibial artery in logistic regression (OR = 2.6; p = 0.01). CONCLUSION: The peroneal artery was the most frequently artery in angiograms of diabetic and non-diabetic patients with CLI. Diabetic and non-diabetic patients did not differ in angiographic findings of the leg.

Methods: a descriptive and cross-sectional study with 1005 type 2 diabetic patients admitted to the Diabetes Care Center in Bayamo, Granma, from September 2008 to June 2011. Data on demographic and clinical variables studied were extracted from medical records. Results: out of 1005 cases studied, 166 (16.5 percent) had peripheral arterial disease. In univariate analysis found that age, (women e» 55 years and e» 45 years in men (OR: 2.71, CI :1.8-4, 0, p = 0.0000)), hypertension (OR: 1 , 68, CI: 1.1-2.4, p = 0.0065), hypertriglyceridemia (OR: 1.65, CI: 1.1 to 2.3, p = 0.0041), hypercholesterolemia (OR : 1.57, CI: 1.1-2.2, p = 0.0088) and metabolic syndrome (OR: 1.53, CI :1,0-2 0.2, p = 0.0244) were significantly associated with developing peripheral arterial disease. Conclusions: peripheral arterial disease is a common complication in persons with type 2 diabetes mellitus in our environment and age, hypertension, dyslipidemia and metabolic syndrome are the highest influence factors on its development

Peripheral arterial embolism of pellets after shotgun injury to the abdomen: A case report.

Dealing with shotgun injury to the abdomen it is important to be aware of the possibility of missile emboli and their potential clinical effects because it usually causes vascular trauma but intravascular missile embolism is relatively rare. Vascular trauma following shotgun injuries may involve laceration of the vessel wall, pseudoaneurysm, arteriovenous fistula or missile embolism. A pellet embolus should be suspected in all cases where gunshot entry wound is present with or without an exit wound. We recently encountered a case of a close-range shotgun injury to the abdomen with subsequent embolisation of pellets to bifurcation of popliteal artery both lower limbs. However, pellet embolus is asymptomatic, there is still debate over best management because conservative management avoids surgical risks and operative removal prevents the possibility of embolus related life threatening complications. This case shows that it is necessary to do whole body imaging in all cases of shotgun injury whether exit wound present or not.

Resistência à proteína C ativada e doença arterial isquêmica em jovem / Resistance to activated protein C and ischemic arterial disease in a young man

A avaliação da resistência à ação da proteína C ativada (rPCA), causada por mutação no fator V (fator V de Leiden), é fator de risco importante para tromboembolia venosa, cujo papel como geradora de obstruções arteriais in situ é um tema ainda controverso. O caso clínico de um jovem com história de coronariopatia, múltiplas lesões cerebrovasculares e doença arterial periférica é relatado. A investigação diagnóstica apontou a rPCA como possível etiologia.

The assessment of activated protein C resistance (APCR) caused by mutations in factor V (factor V Leiden) is an important risk factor for venous thromboembolism, of which role as the originator of arterial obstructions in situ is still a controversial subject. The clinical case of a young patient with history of coronariopathy, multiple cerebrovascular lesions and peripheral artery disease is reported. The diagnostic investigation showed APCR as the possible etiology.
