ABSTRACT
Introducción. La isquemia mesentérica crónica es una entidad infrecuente, con una prevalencia de 0,03 %, donde más del 90 % son debidas a enfermedad arterioesclerótica que compromete principalmente la arteria mesentérica superior. Sus síntomas son dolor abdominal crónico y pérdida de peso, asociado a alteraciones imagenológicas que hacen el diagnóstico. El tratamiento depende de las condiciones clínicas del paciente y el número de vasos comprometidos. Es claro que la enfermedad multivaso sintomática requiere revascularización. Caso clínico. Mujer de 67 años, fumadora activa con antecedentes de hipertensión arterial y dislipidemia, con cuadro de crisis hipertensiva tipo urgencia que requirió manejo en Unidad de Cuidados Intensivos. Se hizo diagnóstico de aneurisma toracoabdominal Crawford IV, oclusión aorto-ilíaca (TASC D) y oclusión crónica del tronco celíaco y la arteria mesentérica superior. Por los síntomas de isquemia mesentérica crónica fue llevada a tratamiento quirúrgico con baipás aorto-bifemoral más baipás retrógrado a la arteria mesentérica superior por vía abierta. Resultado. La paciente tuvo mejoría de la sintomatología y aumentó 13 % del peso al seguimiento a los 3 meses. Conclusión. La isquemia mesentérica crónica es una condición subdiagnosticada, marcador de riesgo cardiovascular, con alta carga de morbilidad y mortalidad, en la cual, con una identificación temprana se puede ofrecer una terapia de revascularización, sea por vía endovascular o abierta, con el fin de mejorar la calidad de vida y la ganancia de peso, y evitar la necrosis intestinal.
Introduction. Chronic mesenteric ischemia is a rare entity, with a prevalence of 0.03%, where more than 90% are due to arteriosclerotic disease that mainly affects the superior mesenteric artery. Its symptoms are chronic abdominal pain and weight loss, associated with imaging alterations that make the diagnosis. Treatment depends on the patient's clinical conditions and the number of vessels involved. It is clear that symptomatic multivessel disease requires revascularization. Clinical case. A 67-year-old woman, an active smoker with a history of high blood pressure and dyslipidemia, presented with an emergency-type hypertensive crisis that required management in the Intensive Care Unit. A diagnosis of Crawford IV thoracoabdominal aneurysm, aorto-iliac occlusion (TASC D), and chronic occlusion of the celiac trunk and superior mesenteric artery was made. Due to the symptoms of chronic mesenteric ischemia, she underwent surgical treatment with aorto-bifemoral bypass plus retrograde bypass to the superior mesenteric artery via an open approach. Result. The patient had improvement in symptoms and gained 13% weight at 3-month follow-up. Conclusion. Chronic mesenteric ischemia is an underdiagnosed condition, a marker of cardiovascular risk, with a high burden of morbidity and mortality, in which, with early identification, revascularization therapy can be offered, either endovascularly or open, in order to improve quality of life and weight gain, and avoiding intestinal necrosis.

Purpose: To evaluate using a biocellulose-based hydrogel as an adjuvant in the healing process of arterial ulcers. Methods: A prospective single group quasi-experimental study was carried out with chronic lower limb arterial ulcer patients. These patients received biocellulose-based hydrogel dressings and outpatient guidance on dressing and periodic reassessments. The primary outcomes were the ulcer-healing rate and product safety, which were assessed by ulcer area measured in photographic records of pre-treatment and posttreatment after 7, 30, and 60 days. Secondary outcomes were related to clinical assessment by the quality-of-life scores (SF-36 and EQ-5D) and pain, evaluated by the visual analogue scale (VAS). Results: Seventeen participants were included, and one of them was excluded. Six patients (37%) had complete wound healing, and all patients had a significant reduction in the ulcer area during follow-up (233.6mm2 versus 2.7mm2) and reduction on the score PUSH 3.0 (p < 0.0001). The analysis of the SF-36 and EQ-5D questionnaires showed a statistically significant improvement in almost all parameters analyzed and with a reduction of pain assessed by the VAS. Conclusions: The biocellulose-based hydrogel was safe and showed a good perspective to promoting the necessary conditions to facilitate partial or complete healing of chronic arterial ulcers within a 60-day follow-up. Quality of life and pain were positively affected by the treatment.

Introdução: a doença arterial obstrutiva periférica (DAOP) tem alta prevalência na população em geral e está associada a elevado risco de eventos cardiovasculares. O índice tornozelo-braquial (ITB), é um exame simples e não invasivo, com alta sensibilidade e especificidade no diagnóstico de DAOP. A patologia pode estar associada a diversos fatores de risco, entre eles a doença renal crônica terminal. Contudo, os dados que avaliam sua prevalência e fatores de risco na população de doentes renais crônicos são escassos. Objetivos: Determinar a prevalência e os fatores de risco da doença arterial obstrutiva periférica em pacientes com insuficiência renal crônica dialítica. Metodologia: trata-se de um estudo transversal, que analisou 117 pacientes com doença renal dialítica. Foram avaliados através de um questionário para identificação dos fatores de risco e submetidos ao teste do ITB, sendo considerado diagnóstico de DAOP quando ITB <0,9. Resultados: o presente estudo evidenciou uma prevalência de DAOP em 11% dos pacientes, sendo 10 classificados como DAOP leve e 3 como moderada. Não foram encontrados pacientes com DAOP severa. Entretanto, 54 pacientes (46,2%) apresentaram rigidez de parede vascular. Assim, foi possível verificar que 67 (57,3%) pacientes apresentaram o ITB alterado. Conclusão: a alta prevalência de DAOP em pacientes com doença renal crônica dialíticafoi análoga ao encontrado por outros autores. É importante ressaltar que pacientes com ITB > 1,3 podem gerar resultados falsos-negativos no diagnóstico de DAOP. Devido a isso, a prevalência pode estar subestimada, o que sugere que o ITB nesses pacientes deve ser avaliado com mais atenção.
Background: peripheral arterial disease (PAD) has a high prevalence in the general population and is associated with a high risk of cardiovascular events. The ankle-brachial index (ABI) is a simple noninvasive exam with high sensitivity and specificity in the diagnosis of PAD. Pathology may be associated with several risk factors, including terminal chronic kidney disease. However, data assessing their prevalence and risk factors in the chronic kidney disease population are scarce. Objectives: to determine the prevalence and risk factors of peripheral arterial disease in patients with dialytic chronic renal failure. Methods: this is a cross-sectional study that analyzed 117 patients with dialytic kidney disease. They were evaluated through a questionnaire to identify risk factors and were submitted to the ABI test, being considered a diagnosis of PAD when ABI <0.9. Results: the present study showed a prevalence of PAD in 11% of the patients, 10 classified as mild and 3 as moderate. No patients with severe PAD were found. However, 54 patients (46.2%) had vascular wall stiffness. Thus, it was possible to verify that 67 (57.3%) patients presented altered ABI. Conclusion: the high prevalence of PAD in patients with dialytic chronic kidney disease was similar to that found by other authors. It is important to highlight that patients with ABI> 1.3 may generate false negative results in the diagnosis of PAD. Because of this, the prevalence may be underestimated, suggesting that ABI in these patients should be evaluated more carefully.

Introducción: La diabetes mellitus constituye un factor de riesgo distintivo en la enfermedad arterial periférica. Esta produce típicamente la afectación de los vasos infrageniculares, asociada con mayor predisposición a ulceración y amputación que en pacientes no diabéticos. Debido al desenlace sombrío de estos pacientes es necesario revascularizar con el fin de salvar la extremidad. Objetivo: Presentar un caso en el que se utilizó la angioplastia simple de la arteria tibial posterior para salvar la extremidad de un paciente diabético. Presentación del caso: Se presenta un caso con diagnóstico de pie diabético isquémico infectado en la extremidad inferior izquierda. Al examen físico se constató lesión isquémica infectada en el quinto y cuarto dedos con extensión al dorso y planta del pie, y patrón esteno-oclusivo distal. Se detectó disminución de los índices de presiones distales. En la arteriografía se apreció oclusión de las arterias tibial anterior y peronea desde su origen, y lesiones esteno-oclusivas en la tibial posterior en el tercio inferior de la pierna. Se realizó angioplastia transluminal percutánea de la tibial posterior y el paciente recuperó pulso en tibial posterior con mejoría hemodinámica. Evolucionó satisfactoriamente y egresó con tratamiento médico. A los cinco meses de operado mantenía su pulso tibial posterior presente y la lesión cicatrizada. Conclusiones: La angioplastia simple de una de las arterias de la pierna puede resultar beneficiosa para la cicatrización de lesiones en el pie, aun siendo estas extensas(AU)
Introduction: Diabetes mellitus is a distinctive risk factor in peripheral artery disease. This typically produces the involvement of the infragenicular vessels, associated with a greater predisposition to ulceration and amputation than in non-diabetic patients. Due to the bleak outcome of these patients it is necessary to revascularize in order to save the limb. Objective: To present a case in which simple angioplasty of the posterior tibial artery was used to save the limb of a diabetic patient. Case Presentation: It is presented a case with a diagnosis of infected ischemic diabetic foot in the left lower extremity. On physical examination, infected ischemic lesion was found in the fifth and fourth toes with extension to the back and soles of the foot, and distal steno-occlusive pattern. Decreases in distal pressure indices were detected. Arteriography showed occlusion of the anterior tibial and peroneal arteries from their origin, and steno-occlusive lesions in the posterior tibial in the lower third of the leg. Percutaneous transluminal angioplasty of the posterior tibial was performed and the patient recovered pulse in the posterior tibial with hemodynamic improvement. The patient progressed satisfactorily and was discharged with medical treatment. Five months after surgery, the kept posterior tibial pulse present and the injury healed. Conclusions: Simple angioplasty of one of the arteries of the leg can be beneficial for the healing of foot injuries, even if these are extensive(AU)

Objective: To examine the effective and safe outcomes of drug-coated balloon (DCB) angioplasty for the treatment of femoropopliteal long lesions in mid-term and long-term follow-up. Methods: The clinical data of 114 patients with symptomatic (Rutherford 2 to 6) femoropopliteal long lesions who underwent angioplasty with DCB between June 2016 and May 2021 at Department of Vascular Surgery,Beijing Tsinghua Changgung Hospital were retrospectively analyzed. A total of 75 males and 39 females were enrolled, aged (71.9±8.4)years (range: 49 to 89 years). Among 138 lesions in 114 patients, there were 111 de nove lesions (80.4%, 111/138). Total occlusions were recanalized in 116 limbs (84.1%, 116/138). The lesion length was (280.9±78.7)mm (range: 150 to 520 mm). DCB angioplasty combined with debulking devices was used in 59 lesions (42.8%, 59/138).The bail-out stent implantation was performed in 27 limbs (19.6%, 27/138). The Kaplan-Meier method was used to evaluate cumulative primary patency rate, freedom from the clinically driven target lesion revascularization (CD-TLR) rate and accumulate survival rate. Univariate and multivariate analyses with Cox proportional hazards models were performed to determine the significant prognostic factors for primary patency. Results: DCB angioplasty was completed in 114 patients. The technical success rate was 98.2%(112/114). The mean follow-up time was 18 months (range: 3 to 54 months).The results showed that primary patency rates at 12, 24 and 36 months postoperatively were 87.5%, 75.2% and 55.1%, respectively. Freedom from CD-TLR rate at 12, 24 and 36 months postoperatively were 92.4%, 81.8% and 68.7%, respectively. Accumulate survival rate at 12, 24 and 36 months postoperatively were 96.2%, 94.0% and 80.2%. Multivariate Cox's regression analyses showed that chronic limb-threatening ischemia(CLTI) (HR=2.629, 95%CI:1.519 to 4.547, P<0.01) and hyperlipidemia (HR=2.228, 95%CI: 1.004 to 4.948, P=0.026) were independent prognosis factors for primary patency in DCB treatment of femoropopliteal long lesions. Conclusions: DCB provided favorable outcomes for the treatment of femoropopliteal long lesions. CLTI and hyperlipidemia are independent prognosis factors for restenosis after DCB angioplasty.

INTRODUCTION@#Percutaneous transluminal angioplasty (PTA) is commonly used to treat patients with chronic limb-threatening ischaemia (CLTI). This study aimed to examine the mortality and functional outcomes of patients with CLTI who predominantly had diabetes mellitus in a multi-ethnic Asian population in Singapore.@*METHODS@#Patients with CLTI who underwent PTA between January 2015 and March 2017 at the Vascular Unit at Singapore General Hospital, Singapore, were studied. Primary outcome measures were 30-day unplanned readmission, two-year major lower extremity amputation (LEA), mortality rates, and ambulation status at one, six and 12 months.@*RESULTS@#A total of 221 procedures were performed on 207 patients, of whom 184 (88.9%) were diabetics. The one-, six- and 12-month mortality rate was 7.7%, 16.4% and 21.7%, respectively. The two-year LEA rate was 30.0%. At six and 12 months, only 96 (46.4%) and 93 (44.9%) patients were ambulant, respectively. Multivariate analysis revealed that preoperative ambulatory status, haemoglobin, Wound Ischaemia and foot Infection (WIfI) score, and end-stage renal failure (ESRF) were independent predictors of one-year ambulatory status. Predictors of mortality at one, six and 12 months were ESRF, preoperative albumin level, impaired functional status and employment status.@*CONCLUSION@#PTA for CLTI was associated with low one-year mortality and two-year LEA rates but did not significantly improve ambulation status. ESRF and hypoalbuminaemia were independent predictors of mortality. ESRF/CKD and WIfI score were independent predictors of loss of ambulation at six months and one year. We need better risk stratification for patients with CLTI to decide between initial revascularisation and an immediate LEA policy.

INTRODUCTION@#Identifying peripheral arterial disease (PAD) during diabetic foot screening (DFS) is crucial in reducing the risk of diabetic foot ulcerations and lower limb amputations. Screening assessments commonly used include absolute systolic toe pressure (ASTP) and toe-brachial index (TBI). There is a lack of research defining the threshold values of both assessment methods. We aimed to compare the accuracy of ASTP and TBI and establish optimal threshold values of ASTP and TBI with reference to the internationally accepted ankle-brachial pressure index (ABPI) screening test, for a multiethnic diabetic population in Singapore.@*METHODS@#A retrospective, observational study of DFS results from January 2017 to December 2017 was conducted. Receiver operating characteristic analysis was conducted for ASTP and TBI using the internationally accepted ABPI cut-off value of ≤0.9 to indicate PAD.@*RESULTS@#A total of 1,454 patients with mean (standard deviation) age of 63.1 (12.4) years old were included. There were 50.8% men and 49.2% women, comprising 69.7% Chinese, 13.5% Indian, 10.1% Malay and 6.7% other ethnicities. Areas under the curve for ASTP and TBI were 0.89 (95% confidence interval [Cl] 0.85-0.94) and 0.94 (95% Cl 0.90-0.98), respectively, and the difference was statistically significant (P<0.001). Derived optimal threshold values to indicate ABPI≤0.9 for ASTP and TBI were <95.5mmHg (specificity 0.86, sensitivity 0.84) and <0.7 (specificity 0.89, sensitivity 0.95), respectively.@*CONCLUSION@#ASTP or TBI may be used to detect ABPI-determined PAD in DFS. The optimal threshold values derived from a multiethnic Asian diabetic population were <95.5mmHg for ASTP and <0.7 for TBI.

O diabetes melito é o maior fator de risco para doença arterial coronariana. Além da longa duração de diabetes, outros fatores, como presença de doença arterial periférica e tabagismo são fortes preditores para anormalidades na cintilografia de perfusão do miocárdio. O objetivo deste estudo foi avaliar o impacto dos fatores de risco de pacientes diabéticos nos resultados da cintilografia de perfusão do miocárdio e comparar com os resultados de pacientes não diabéticos em uma clínica de medicina nuclear. Foi realizado um estudo transversal retrospectivo por meio da análise de prontuários de pacientes que realizaram cintilografia miocárdica no período de 2010 a 2019. Foram avaliados 34.736 prontuários. Analisando a fase de estresse da cintilografia de perfusão do miocárdio, os portadores de diabetes melito precisaram receber estímulo farmacológico duas vezes mais que os não diabéticos para sua realização. Também foram avaliados fatores que tivessem impacto negativo no resultado da cintilografia de perfusão do miocárdio, e foi visto que o diabetes melito (33,6%), a insulinoterapia (18,1%), a hipertensão arterial sistêmica (69,9%), a dislipidemia (53%), o sedentarismo (83,1%), o uso de estresse farmacológico (50,6%), a dor torácica típica (8,5%) e a angina limitante durante o teste (1,7%) estiveram associados significativamente (p<0,001) a anormalidades neste exame.

Diabetes mellitus (DM) is the greatest risk factor for coronary artery disease. In addition to a long duration of diabetes, the presence of peripheral arterial disease and smoking are strong predictors of abnormalities on myocardial perfusion scintigraphy (MPS). This study aimed to assess the impact of risk factors in diabetic patients on MPS results and compare them with those of non-diabetic patients in a nuclear medicine clinic. A retrospective cross-sectional study was performed through the analysis of the medical records of patients who underwent MPS in 20102019. A total of 34,736 medical records were evaluated. Analyzing the stress phase of MPS, DM patients required two-fold more pharmacological stimulation than non-diabetic patients for MPS. Factors that negatively impact the MPS results were also evaluated, and DM (33.6%), insulin therapy (18.1%), systemic arterial hypertension (69.9%), dyslipidemia (53%), sedentary lifestyle (83.1%), use of pharmacological stress (50.6%), typical chest pain (8.5%), and limiting angina during the test (1.7%) were significantly associated (p < 0.001) with test abnormalities.

Introdução: Os fatores associados ao comprometimento da qualidade de vida em pacientes com isquemia crônica ameaçadora ao membro não estão bem estabelecidos. Objetivo: Verificar se existe associação entre a qualidade de vida e os índices de rigidez arterial, velocidade de onda de pulso (VOP) e o índice de aumentação normalizado para a frequência cardíaca de 75 bpm (AIx@75). Métodos: Trata-se de um estudo transversal, observacional, com a participação de 17 pacientes (65,65 ±11,79 anos) com isquemia crônica ameaçadora ao membro definida pela classificação de Rutherford 4, 5 e 6, e com o índice tornozelo-braço (ITB) < 0,80. A avaliação dos parâmetros vasculares e os índices de rigidez arterial foram realizadas com o aparelho Mobil-O-Graph ® que gera a onda de pulso aórtica a partir da oscilometria da artéria braquial. A qualidade de vida foi avaliada pelo questionário Vascular quality of life questionaire (VascuQoL-6), versão curta, desenvolvido especificamente para avaliar pacientes com comprometimento circulatório, arterial ou venoso. Resultados: Os valores do ITB e do escore de qualidade de vida foram 0,48 ± 0,14 e 15,88 ± 1,03; respectivamente. Dos 17 pacientes, 12 apresentavam hipertensão arterial sistólica e dezesseis apresentaram a VOP maior que 10 m/s. Não foram observadas correlações entre o escore de qualidade de vida com o AIx@75 (p=0,54 e r=0,16), a VOP (p=0,332 e r=0,248) e o ITB (p=0,707 e r=0,098). Conclusão: O presente estudo demonstrou que pacientes com isquemia crônica ameaçadora ao membro apresentam comprometimento importante da qualidade de vida sem associação com os índices de rigidez arterial e ITB.
Introduction: The factors associated with impaired quality of life in patients with chronic limb-threatening ischemia are not well established. Objective: Check whether there is an association between quality of life and arterial stiffness indexes, pulse wave velocity (PWV) and the augmentation index corrected to 75 beats per minute heart rate (AIx@75). Methods: This is a cross-sectional, observational study, with the participation of 17 patients (65.65 ± 11.79 years) with chronic limb-threatening ischemia defined by the Rutherford classification 4, 5 and 6, and with the ankle-arm index (ABI) < 0.80. The evaluation of vascular parameters and arterial stiffness indeces was performed with the MobilO-Graph ® device that generates the aortic pulse wave from the brachial artery oscillometry. Quality of life was assessed using the questionnaire Vascular quality of life questionaire (VascuQoL-6), short version, developed specifically to evaluate patients with circulatory, arterial or venous involvement. Results: The values of the ITB and the quality of life score were 0.48 ± 0.14 and 15.88 ± 1.03; respectively. Of the 17 patients, 12 had systolic arterial hypertension and sixteen had PWV greater than 10 m / s. No correlations were observed between the quality of life score with AIx @ 75 (p = 0.54 and r = 0.16), PWV (p = 0.332 and r = 0.248) and ABI (p = 0.707 and r = 0.098). Conclusion: The present study demonstrated that patients with chronic limb-threatening ischemia present significant impairment of quality of life without association with arterial stiffness and ABI.

Resumo Contexto Na pandemia de covid-19, os serviços de saúde diminuíram os atendimentos e procedimentos eletivos. Pacientes de cirurgia vascular são grupo de risco para adquirir formas graves da infecção, ao mesmo tempo que são suscetíveis a apresentar complicações de suas doenças de base caso não tenham acompanhamento rotineiro. Dessa forma, faz-se necessário entender os impactos e as consequências diretas e indiretas da pandemia com relação aos pacientes vasculares. Objetivos Avaliar o impacto de 1 ano de pandemia em um serviço de Cirurgia Vascular, assim como a mudança do perfil de cirurgias no mesmo período. Métodos Foi feita a análise de prontuários de pacientes submetidos a cirurgias eletivas e de urgência entre 2019 e 2021. Em conjunto, foi realizada uma revisão de literatura com as palavras-chave "cirurgia vascular", "covid-19" e "amputações". Os dados foram analisados com o programa computacional Stata/SE v.14.1 (StataCorpLP, EUA). Resultados Foram identificadas 1.043 cirurgias no período de estudo, sendo 51,6% pré-pandemia e 48,4% durante a pandemia. Observou-se redução no número de cirurgias eletivas e aumento no número de amputações de membros inferiores e desbridamentos cirúrgicos. Foi possível observar também aumento de pacientes com doença arterial obstrutiva periférica com classificação de Rutherford avançada, assim como de casos de pé diabético. Conclusões A diminuição dos atendimentos eletivos e o receio dos pacientes em procurar os serviços de saúde durante o período da pandemia são os prováveis motivos que justificam o aumento da gravidade dos quadros dos pacientes, com maior necessidade de amputação de membros inferiores, desbridamento cirúrgico e mudanças no perfil de cirurgia do serviço.
Abstract Background During the COVID-19 pandemic, healthcare services reduced the number of elective procedures performed. Vascular surgery patients are a group at risk of contracting severe forms of the infection, but are also susceptible to complications of their underlying diseases if they do not receive routine care. It is therefore necessary to understand the direct and indirect impacts and consequences of the pandemic on vascular patients. Objectives To assess the impact of 1 year of the pandemic on a vascular surgery service and changes to the profile of surgeries during the same period. Methods An analysis was conducted of the medical records of patients who underwent elective and emergency surgery from 2019 to 2021. A review of the literature was also conducted, using the search terms "vascular surgery", "COVID-19", and "amputations". Data were analyzed with Stata/SE v.14.1 (StataCorpLP, United States). Results A total of 1,043 surgeries were identified during the study period, 51.6% conducted pre-pandemic and 48.4% performed during the pandemic. There was a reduction in the number of elective surgeries and an increase in the number of lower limb amputations and surgical debridements. Increases were also observed in the proportion of patients with peripheral arterial occlusive disease with advanced Rutherford classifications and in the number of cases of diabetic foot. Conclusions The reduction in elective care and patients' reluctance to seek health services during the pandemic are the probable causes of increased severity of patient status, with greater need for lower limb amputation and surgical debridement and changes to the profile of the surgery performed at the service.
