ABSTRACT
OBJECTIVE: Through a retrospective analysis of 1,203 cases of referral from primary healthcare units to a specialized quaternary vascular surgical service, the findings of this study revealed a high proportion of inappropriate referrals, which may represent a substantial subutilization of this highly complex service. Consequently, in this study, we aimed to evaluate 1,203 cases of referral to a quaternary vascular surgical service, in São Paulo, Brazil, over a 6-year period, to assess the appropriate need for referral; in addition to the prevalence of surgical indications. METHODS: In this retrospective analysis, we reviewed the institutional records of participants referred from Basic Healthcare Units to a vascular surgical service inside the Brazilian Unified Health System, between May 2015 and December 2020. Demographic and clinical data were collected. The participants were stratified, as per the reason for referral to the vascular surgical service, previous imaging studies, and surgical treatment indications. Referral appropriateness and complementary examinations were evaluated for each disease cohort. Finally, the prevalence of cases requiring surgical treatment was defined as the outcome measure. RESULTS: Of the 1,203 referrals evaluated, venous disease was the main reason for referral (53%), followed by peripheral arterial disease (19.4%). A considerable proportion of participants had been referred without complementary imaging or after a long duration of undergoing an examination. Referrals were regarded as inappropriate in 517 (43%) cases. Of these, 32 cases (6.2%) had been referred to the vascular surgical service, as the incorrect specialty. The percentage of referred participants who ultimately underwent surgical treatment was 39.92%. Carotid (18%) and peripheral arterial diseases (18.4%) were correlated with a lower prevalence of surgical treatments. CONCLUSION: The rate of referral appropriateness to specialized vascular care from primary care settings was low. This may represent a subutilization of quaternary surgical services, with low rates of surgical treatment.

Resumen: La disección coronaria espontánea ha surgido como una causa interesante y poco reconocida de síndrome coronario agudo no aterosclerótico. Ocurre más frecuentemente en mujeres jóvenes, donde de forma importante puede asociarse a anomalías arteriales no coronarias. La clave para un tratamiento oportuno es el diagnóstico precoz que impida su evolución a cuadros más severos. Se presenta el caso de una mujer de 36 años con un síndrome coronario agudo secundario a una disección coronaria espontánea bi-arterial que evolucionó de forma grave a una insuficiencia cardíaca aguda. El objetivo es informar un cuadro poco usual y proporcionar evidencia que respalde el cómo debe enfrentarse.
Abstract: Spontaneous coronary dissection is an important cause of acute non-atherosclerotic coronary syndrome. It occurs more frequently in young women, often without significantly associated coronary arterial anomalies. Early diagnosis is a key to prompt treatment, in order to prevent severe complications. We report the case of a 36-year-old woman with an acute coronary syndrome secondary to spontaneous bi-arterial coronary dissection progressing to severe acute heart failure. A discussion of the management of this condition is included.

BACKGROUND: The precise epidemiological evaluation of amputations is difficult. It is a serious public health and economic problem with a high death rate. The proportion of amputees with pre-amputation vascular status remains unknown. The main objective of our study was to evaluate the proportion of patients with lower limb amputation who had a pre-procedural vascular assessment. The secondary objectives were to evaluate the risk of amputation at the admission of these patients, estimate the incidence of amputations in Martinique, and to collect epidemiological data on this category of patients. MATERIAL AND METHODS: We conducted an epidemiological, retrospective, and observational study, over the year 2018 between January 01 and December 31, including all adults' patients who underwent an amputation of the lower limb at the university hospital center of Martinique. RESULTS: Among the 170 included patients, 79 (46%) patients had a major lower limb amputation. The incidence of amputations in 2018 was estimated at 48.9/100,000 inhabitants. The vascular assessment was performed for 110 (65%) patients. For the other 60 (35%) patients who did not have a vascular assessment, 53 (88%) had a severe infection. This assessment was significantly related to the amputation level: a vascular assessment was performed in 97 (70%) patients with below the knee amputation versus 13 (41%) patients with above the knee amputation (P<0.01). The WIfI classification system found a high risk of amputation for 152 (89%) of patients but also a benefit of revascularization ranked high for 138 (81%) of them. The origin of amputation was limb ischemia for 125 (68%) patients. CONCLUSION: A significant number of patients who underwent lower limb amputation did not have a pre-procedural vascular assessment. Many improvements in the health care are therefore to be implemented. The upcoming M@diCICAT project in Martinique will contribute in the improvement of patient management. The incidence of amputation in Martinique is considered high compared to other countries (French national incidence in 2003=24.8/100,000 inhabitants), and it seems to have remained stable since 2008. Our population is considered to be at high risk of amputation by the SVS-WIfI classification. This score seems adapted to anticipate the evolution of these patients and could be useful in daily practice.

Spontaneous coronary artery dissection (SCAD) is considered an often underdiagnosed acute coronary syndrome, with few cases described in literature. Its association with physical exercise among young patients without risk factors or atherosclerotic disease (CAD) is even rarer. For this reason, a study was conducted on the subject, describing the clinical conditions, conduct and evolution regarding the suspicion of spontaneous exercise-related coronary artery dissection in three young patients without risk factors or CAD. Clinical conditions varied, with predominant recurrent chest pain. Age range from 20 to 31 years. All patients underwent coronary angiography, which showed no CAD but suggested SCAD. Investigations concerning other causes of coronary obstruction were negative. The right coronary artery was affected in two cases, and the anterior descending artery was affected in one case. Only one of the three patients had recurrent events within five years from the primary event. Technological advances will enable increased dissection identification in acute coronary syndromes. Improving the knowledge about the related clinical conditions is necessary, as an attempt to provide warnings and improve the suspicion of spontaneous exercise-related coronary artery dissection among those who have symptoms of coronary insufficiency, thus reducing the frequent underdiagnosis. The best treatment and prognosis for this disease remains uncertain.

Spontaneous coronary artery dissection (SCAD) is characterized by tear of the inner layer in the coronary artery, creating a false lumen between the inner and central layer. Its infrequent incidence often leads to delay in diagnosis posing challenges in management. There are currently no guidelines for the treatment of this condition. We describe an adult patient who presented with multiple episodes of ventricular fibrillation, in whom cardiac catheterization showed SCAD, treated by off-pump coronary artery bypass.

OBJECTIVE: To compare the use of the radiofrequency thermoablation of the saphenous vein with the ligation technique, and complete removal of the saphenous vein, from the saphenofemoral junction to the ankle. METHODS: A total of 49 patients with chronic venous disease in the Comprehensive Classification System for Chronic Venous Disorders (CEAP) classes 2 to 4 for clinical signs, etiology, anatomic distribution and pathophysiology, were assessed at baseline, after 4 weeks, and after 1 year. The parameters assessed were complications, period of absence from activities, Venous Clinical Severity Score (VCSS) and quality of life scores according to Aberdeen Varicose Veins Questionnaire (AVVQ). They were re-examined 1 and 3 years after treatment to evaluate recurrence rates. RESULTS: The success rate per limb (p=0.540), VCSS (p=0.636), AVVQ (p=0.163), and clinical complications were similar in the two treatment groups. Nevertheless, the radiofrequency thermoablation group had significant shorter length of hospital stay (0.69±0.47) and absence from activities (8.62±4.53), p<000.1. CONCLUSION: Patients submitted to radiofrequency thermoablation had an occlusion rate, clinical recurrence and improvement in quality of life comparable to removal of the saphenous vein. However, these patients spent less time hospitalized and away from their daily activities during recovering.

INTRODUCTION: Perforator veins (PVs) play an important role in the development of chronic venous insufficiency and ulceration. Procedures to eliminate incompetence and reflux in PV may include open surgery, subfascial endoscopic surgery, intravenous ablation techniques and sclerotherapy. With the aim of filling the evidence gap, this is a protocol for a systematic review that will assess the effects of any form of intervention for the treatment of pathologic PVs of the lower limbs in patients with chronic venous disease. METHODS AND ANALYSIS: Systematic searches will be carried out in MEDLINE, EMBASE, Cochrane CENTRAL, IBECS and LILACS databases at a minimum without date or language restrictions for relevant randomised controlled trials (RCTs) and quasi-RCTs (trials in which the method of allocation is not truly random). In addition, a search will also be carried out in the WHO International Clinical Trials Registry Platform, in the clinical trial registries of ClinicalTrials.gov and in the grey literature source OpenGrey.eu. The RCT and quasi-RCT comparison techniques isolated or in combination for treating PVs will be considered. Three review authors will independently perform data extraction and quality assessments of data from included studies, and any disagreements will be resolved by discussion. The primary outcomes will be wound healing and pain. Secondary outcomes will include oedema, adverse events, recurrence or recanalisation, quality of life and economic aspects. The Cochrane handbook will be used for guidance. If the results are not appropriate for a meta-analysis in RevManV.5 software (eg, if the data have considerable heterogeneity and are drawn from different comparisons), a descriptive analysis will be performed. ETHICS AND DISSEMINATION: Ethics committee approval is not necessary. We intend to update the public registry used in this review, report any important protocol amendments and publish the results in a widely accessible journal. PROSPERO REGISTRATION NUMBER: CRD42018092974.

RESUMO Objetivo: Comparar o uso da termoablação por radiofrequência da veia safena com a técnica de ligação e retirada completa da veia safena da junção safeno-femoral ao tornozelo. Métodos: Foram avaliados 49 pacientes com doença venosa crônica nas categorias 2 a 4 (Comprehensive Classification System for Chronic Venous Disorders − CEAP) para classificação clínica, etiológica, anatômica e fisiopatológica, no início do estudo, 4 semanas e 1 ano após o procedimento. Os parâmetros analisados foram complicações, período de ausência de atividades,(Venous Clinical Severity) Score revisado (R-VCSS) e escore de qualidade de vida de acordo com o Aberdeen Varicose Veins Questionnaire(AVVQ). Os pacientes foram reexaminados 1 e 3 anos após o tratamento, para avaliar as taxas de recorrência. Resultados: As taxas de sucesso por membro (p=0,540), VCSS (p=0,636), AVVQ (p=0,163) e complicações clínicas foram semelhantes nos dois grupos. No entanto, o grupo termoablação por radiofrequência teve períodos de internação significativamente mais curtos (0,69±0,47) e ausência de atividades (8,62±4,53), com p<000,1. Conclusão: Pacientes submetidos à termoablação por radiofrequência apresentaram taxa de oclusão, recidiva clínica e melhora da qualidade de vida comparáveis à retirada completa da veia safena. No entanto, esses pacientes passaram menos tempo internados e ausentes de suas atividades diárias durante a recuperação.

Intravascular papillary endothelial hyperplasia (IPEH) is an unusual benign, non-neoplastic vascular lesion that usually occurs in skin, but is uncommon in the oral cavity. Herein, we review the pertinent literature of oraiiPEH and report a new mixed form. A 61-year- old man presented with an ulcerated nodule in the lingual portion of the gingiva related to the left mandibular canine. An excisional biopsy was performed presuming the clinical diagnosis of pyogenic granuloma. Histopathological analysis showed areas of granulation tissue consistent with pyogenic granuloma. But in addition, there were thin-wall dilated vessels with papillary projections of endothelial cells producing vascular channels, associated with an area of organizing thrombus. These microscopic findings led to the diagnosis of pyogenic granuloma associated with IPEH. The immunohistochemical reactions revealed a diffuse positivity of the vascular cells for CD-34 and smooth muscle actin antibodies.In addition,there was partial positivity for podoplanin and negativity for CD-1OS in the IPEH areas. No signs of recurrence were observed after 6 months of follow-up. The most prevalent site of IPEH in the oral region is the lower lip. IPEH is slightly more common in women and exhibits peaks of prevalence between the fourth and sixth decades of life.

INTRODUCTION: Spontaneous coronary artery dissection is a sudden separation between the layers of a coronary artery wall, non-iatrogenic or trauma related, that has been recognized as an important cause of myocardial infarction. OBJECTIVE: To report an emblematic case, in terms of angiographic images, clinical presentation and predisposing factors, whose clinical management failure led to surgical intervention. METHODS: A previously healthy 48-year-old male farmer was admitted to the emergency room complaining of anterior chest pain described as "tearing", which started after physical exertion. Anterior wall ST-segment depression was observed in the electrocardiogram and troponin levels were increased. The patient then underwent coronary catheterization. Angiography showed a tortuous left anterior descending coronary artery with a dissection line involving proximal and middle segments, resulting in mild to moderate luminal stenosis. At first, a conservative approach was chosen. Control cardiac catheterization, 3 months later, showed dissection progression to the distal segment. RESULTS: The patient was referred to surgical treatment. Internal thoracic artery and a great saphenous vein graft were used to revascularize the target vessels. He had an uneventful postoperative course. CONCLUSION: In this report, we describe a typical clinical manifestation of an uncommon cause of acute myocardial infarction. The dissection was started by an extreme physical effort, which is a known triggering factor. Management of these cases is always challenging because there are no evidence-based therapies or guideline-based recomendations.

Abstract: The torsion of vessels after liver transplantation rarely occurs. Likewise, calcification of a liver graft has seldom been reported. This report details a case which had torsion of the left hepatic vein on the seventh day after living-related donor liver transplantation. The torsion was reduced soon after re-exploration; however, congestion with partial necrosis of the graft occurred. On the follow-up imaging studies, some resolution of necrosis and graft regeneration were found, yet geographic calcification of the liver graft appeared. The patient died of pneumonia after 13 weeks, post-operation. The avoidance such torsion of vessels is necessary and important.(AU)
