RESUMO

INTRODUCTION: Abdominal aortic aneurysm (AAA) is a growing public health problem, and not all patients have access to surgery when needed. This study aimed to analyze spatiotemporal variations in AAA mortality and surgical procedures in Brazilian intermediate geographic regions and explore the impact of different surgical techniques on operative mortality. METHODS: A retrospective longitudinal study was conducted to evaluate AAA mortality from 2008 to 2020 using space-time cube (STC) analysis and the emerging hot spot analysis tool through the Getis-Ord Gi* method. RESULTS: There were 34,255 deaths due to AAA, 13,075 surgeries to repair AAA, and a surgical mortality of 14.92%. STC analysis revealed an increase in AAA mortality rates (trend statistic = +1.7693, p = 0.0769) and a significant reduction in AAA surgery rates (trend statistic = -3.8436, p = 0.0001). Analysis of emerging hotspots revealed high AAA mortality rates in the South, Southeast, and Central-West, with a reduction in procedures in São Paulo and Minas Gerais States (Southeast). In the Northeast, there were extensive areas of increasing mortality rates and decreasing procedure rates (cold spots). CONCLUSION: AAA mortality increased in several regions of the country while surgery rates decreased, demonstrating the need for implementing public health policies to increase the availability of surgical procedures, particularly in less developed regions with limited access to services.

RESUMO

Background: Studies on the prevalence of rare visceral aneurysms are still scarce and the few studies that have focused on these aneurysms present prevalence rates in groups of patients with visceral aneurysms, but little is known about their prevalence in the general population. Objectives: To assess the prevalence of rare visceral aneurysms on CAT scans performed for diagnosis and follow-up of patients with other vascular pathologies. Methods: This cross-sectional study began by accessing all reports from CAT scans performed between January 2005 and July 2021 at a private hospital of excellence located in the city of São Paulo. A software program for pre-indexed reports was used to search the Radiological Information System (RIS) database to identify reports of patients with intra-abdominal aneurysms. Results: CAT scan reports from 92,883 patients were accessed. Of these, 2,597 (2.795%) showed intra-abdominal aneurysms, 937 (1.063%) of which were visceral, including 158 (0.171%) rare visceral aneurysms, which were more frequent among male patients and in the following segments: celiac trunk (0.098%), superior mesenteric (0.033%), left gastric (0.010%), pancreatic-duodenal (0.009%), and gastroduodenal arteries (0.005%) and the pancreatic arch (0.004%). Lower prevalence was found in other segments. Additional findings revealed concomitance of rare visceral aneurysms with other intra-abdominal aneurysms ranging from 11.11% to 66.67%. Conclusions: The prevalence of rare visceral aneurysms in a large population undergoing CAT scan was 0.171%, with greater involvement in male patients.

RESUMO

Background: The use of compression dressings after phlebectomy is based solely on clinical experience due to the lack of a unified set of definitive recommendations, which makes clinical practice extremely heterogeneous. Objectives: To evaluate compression therapy with elastic stockings for 7 days after phlebectomy. Methods: We randomly allocated 104 lower limbs with disease classified as C1 and C2 to 1 of 2 groups: an intervention group (64 limbs) - wearing elastic compression stockings for the first 7 days after phlebectomy; or a control group (40 limbs) - given conventional bandaging for 24 hours postoperatively. We compared clinical response by analyzing the evolution of symptoms, hematoma formation, and preoperative vs. postoperative limb volume. Results: Pain (median 1.0 vs. 1.5, p=0.0320) and limb volume (mean 43.7 vs. 99.8, p=0.0071) were significantly improved in patients wearing elastic compression stockings for 7 days after phlebectomy compared with controls. Conclusions: Use of elastic compression therapy for 7 days after phlebectomy was effective for improving pain and lower limb volume.

Contexto: O uso de curativos após flebectomia é baseado apenas na experiência clínica, visto que não existe um conjunto unificado de recomendações definitivas, o que torna a prática clínica extremamente variável. Objetivos: Avaliar o uso de terapia elástica compressiva por 7 dias após flebectomia. Métodos: Cento e quatro membros inferiores, classificados como CEAP C1 e C2, foram randomizados em dois grupos: grupo de intervenção (64 membros) ­ uso de meia elástica por 24 horas após a cirurgia ­ e grupo controle (40 membros) ­ uso de curativo convencional por 7 dias após a cirurgia. A resposta clínica foi comparada por meio de análise da evolução dos sintomas, de hematoma e do volume dos membros antes e depois da cirurgia. Resultados: Os pacientes submetidos a terapia compressiva elástica apresentaram melhora significativa na dor (mediana 1,0 vs. 1,5; p=0,0320) e no volume dos membros (média 43,7 vs. 99,8; p=0,0071) em comparação ao grupo controle. Conclusões: O emprego da terapia compressiva elástica por 7 dias após flebectomia mostrou-se efetivo na melhora da dor e do volume dos membros inferiores.

RESUMO

Resumo Contexto Ainda são incomuns os estudos de prevalência de aneurismas viscerais raros, e os poucos estudos que focalizaram esses aneurismas observam taxas de prevalência em grupos de pacientes com aneurismas viscerais, mas pouco se conhece sobre a sua prevalência na população geral. Objetivos Avaliar a prevalência de aneurismas viscerais raros em angiotomografias realizadas para diagnóstico e seguimento de pacientes com diferentes patologias vasculares. Métodos Este estudo transversal partiu do acesso a todos os laudos de angiotomografias realizadas entre janeiro de 2005 e julho de 2021 em hospital privado de excelência situado na cidade de São Paulo. Foi utilizado um programa de mecanismo de busca de laudos pré-indexados, cuja base de dados é o Sistema de Informação Radiológica (RIS), para acesso aos laudos de pacientes com aneurismas intra-abdominais. Resultados Foram acessados laudos de angiotomografias de 92.883 pacientes, dos quais 2.597 (2,795%) apresentavam aneurismas intra-abdominais, sendo 937 (1,063%) viscerais, incluindo 158 (0,171%) aneurismas viscerais raros, mais frequente entre homens e nos seguintes segmentos: tronco celíaco (0,098%), artéria mesentérica superior (0,033%), artéria gástrica esquerda (0,010%), artéria pancreático-duodenal (0,009%), artéria gastroduodenal (0,005%) e arco pancreático (0,004%). Prevalências menores foram encontradas em outros diferentes segmentos. Achados adicionais revelaram taxa de concomitância de aneurismas viscerais raros com outros aneurismas intra-abdominais entre 11,11% e 66,67%. Conclusões A prevalência de aneurismas viscerais raros em ampla população submetida a angiotomografias foi de 0,171%, com maior comprometimento nos pacientes do sexo masculino.

RESUMO

We have reported a case of a 36-year-old woman with flank and pelvic pain and hematuria. She had posterior nutcracker syndrome and pelvic varices involving one anterior and three posterior renal veins (including one major vein). We used a complete endovascular approach, which included stent implantation in the major posterior renal vein and left gonadal vein embolization. During a 12-month follow-up period, the patient had had no symptoms and good computed tomography results. Endovascular treatment represents a safe and successful option for patients with nutcracker syndrome and pelvic varices involving the anterior and posterior renal veins.

RESUMO

Background: Chronic venous insufficiency affects the lives of many people and therefore constitutes a public health problem. Knowledge of the drainage patterns of reflux from varicose veins secondary to incompetent saphenous veins is essential to define the best therapeutic management. Objectives: To determine the reflux drainage patterns from varicose veins originating in incompetent GSV, the prevalence of perforating veins (PV), and their relationships with symptoms. Methods: 55 ultrasound reports were analyzed to determine the drainage patterns of reflux from the GSV, location and diameter of PV drainage, and staging of symptoms. Results: In 64% of the sample, reflux from varicose veins drained to PVs, in 4% reflux drained to the GSV itself, in another 4% drainage was to the small saphenous vein, and in 29% drainage was to varicose trunk veins in which no direct communication with the deep system could be identified. No associations were observed between symptoms and reflux drainage patterns or PV diameters. Conclusions: For this sample, PVs were responsible for draining flow from varicose veins in 64% of cases. Neither PV diameters nor GSV reflux patterns were associated with severity of symptoms.

Introdução: A insuficiência venosa crônica impacta a vida de muitas pessoas, constituindo-se, assim, como um problema de saúde pública. Conhecer o padrão de drenagem do refluxo das varizes associadas à veia safena incompetente é fundamental para definir a melhor programação terapêutica. Objetivos: Determinar os padrões de drenagem do refluxo de varizes originadas da veia safena magna incompetente, a prevalência de veias perfurantes e a relação com os sintomas. Métodos: Foram analisados 55 registros ultrassonográficos de pacientes com refluxo da veia safena magna para determinar padrões de drenagem do refluxo dessa veia, pontos de refluxo das varizes, localização e diâmetro das perfurantes de drenagem e graduação dos sintomas. Resultados: O principal padrão de refluxo encontrado foi originado da junção safenofemoral com comprometimento proximal da veia safena magna. Em 64% dos pacientes, o refluxo das varizes drenou para veias perfurantes - 4% drenavam para a própria veia safena magna; em outros 4%, a drenagem era para a veia safena parva; e, em 29%, a drenavam destinava-se para varizes tronculares em que não se identificou comunicação direta com o sistema venoso profundo. Não foi observada associação dos sintomas com os padrões de drenagem do refluxo ou diâmetro das perfurantes. Conclusão: Para essa amostra, as veias perfurantes foram responsáveis pelo escoamento do fluxo oriundo das varizes em 64% dos casos. O diâmetro das veias perfurantes e o padrão de refluxo da veia safena não estiveram associados à gravidade dos sintomas.

RESUMO

AIM: The aim of the present study was to show that an increase in weight leads to the aggravation of limited joint mobility. METHOD: One hundred sixteen patients with varicose veins of the lower limbs and body mass index (BMI) higher than 30 kg/m2 were evaluated at the Belczak Clinic in Maringá, Brazil. All patients were evaluated by the same physician, and the goniometric readings were performed on all patients by a physiotherapist. The participants were then divided into three groups based on BMI: Group I-BMI between 30 and 40. Group II-BMI between 40 and 50, and Group III-BMI > 50. RESULTS: There is a significant difference between the groups detected. CONCLUSION: The present findings show that an increased BMI in obese individuals with chronic venous disease is associated with a progressive limitation of ankle mobility.
