- ItemAcesso aberto (Open Access)Avaliação da anatomia arterial no pé torto congênito através da ultrassonografia com doppler colorido(Sociedade Brasileira de Ortopedia e Traumatologia, 2008-01-01) Pinto, Jose Antonio [UNIFESP]; Blumetti, Francesco Camara [UNIFESP]; Iha, Luiz Alberto Nakao [UNIFESP]; Terasaka, Marcos Kiyoshi [UNIFESP]; Sodre, Henrique [UNIFESP]; Ishida, Akira [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)OBJECTIVE: This investigation intended to evaluate anterior and posterior tibial arteries at the ankle joint level in congenital clubfoot, by using color Doppler ultrasound (CDU). MATERIAL AND METHOD: Twenty patients with idiopathic clubfoot were selected, from which 18 had unilateral involvement and two had bilateral involvement. Of the 18 patients with unilateral clubfoot, 16 went through surgical treatment and the other two were submitted to conservative treatment with serial casting. Of the bilateral cases, one patient was treated surgically and the other was treated with serial casting. All patients were clinically and radiographically assessed. We used the functional rating as described by Lehman. Then, CDU was applied bilaterally at the ankle joint level, trying to identify both posterior and anterior tibial arteries. RESULTS: In our present series of 20 cases with idiopathic clubfoot, in just one patient we could not identify the anterior tibial artery at the ankle joint level. In 12 patients who have had their arterial flow speeds and diameters measured by UDC, a positive correlation was found between functional level and anterior tibial artery diameter. No statistically significant differences were found between both flow speed and diameter of anterior tibial artery of the normal side, when compared to the affected side (in patients with unilateral disease). CONCLUSION: In our sample, we could not find any significant differences in arterial morphology and flow speed between the normal and the affected side. Furthermore, we noticed that the better the clinical result of clubfoot correction, the larger the diameter of anterior tibial artery in affected feet.
- ItemSomente MetadadadosAvaliação da fossa olfatória e da artéria etmoidal anterior pela tomografia computadorizada no plano coronal(Universidade Federal de São Paulo (UNIFESP), 2007) Souza, Soraia Ale [UNIFESP]; Ajzen, Sergio Aron [UNIFESP]Objetivos: avaliar a profundidade das fossas olfatorias, segundo a classificacao de Keros; determinar a frequencia de assimetria na altura e na inclinacao lateral da lamela lateral da lamina crivosa entre os lados do mesmo individuo; identificar os reparos anatomicos que caracterizam o trajeto da arteria etmoidal anterior (AEA) na parede medial da orbita e na parede lateral da fossa olfatoria; verificar a correlacao entre a presenca de pneumatizacao supra-orbitaria e o trajeto do canal da AEA (canal etmoidal anterior). Metodos: analise retrospectiva de 200 tomografias computadorizadas dos seios da face no plano coronal, realizadas de agosto a dezembro de 2006. Foram feitas medidas da profundidade da fossa olfatoria e determinadas as alteracoes de simetria do teto dos seios etmoidais quanto a altura e a inclinacao lateral das lamelas laterais da lamina crivosa. Verificou-se a frequencia de identificacao dos reparos anatomicos para a localizacao da AEA, na parede medial da orbita (forame etmoidal anterior) e do sulco etmoidal anterior na parede lateral da fossa olfatoria. Foi correlacionada a presenca de pneumatizacao supra-orbitaria com o trajeto do canal da AEA. Resultados: o tipo de Keros mais encontrado foi o tipo 11 (73 por cento), seguido do tipo I (26,3 por cento) e do tipo 111 (0,5 por cento). Em 12 por cento (24 exames) havia assimetria entre os lados quanto a altura do teto do seio etmoidal e em 48,5 por cento (97 exames) observou-se assimetria do contorno do teto, com inclinacao lateral da lamela lateral da lamina crivosa de um dos lados. Pneumatizacao supra-orbitaria foi identificada em 35 por cento (70 exames). O canal da AEA foi caracterizado em 40,5 por cento (81 exames). O sulco etmoidal anterior foi visualizado em 98 por cento (196 dos exames) e o forame etmoidal anterior foi identificado em todos os exames (100 por cento). Houve diferenca estatisticamente significante entre a presenca de pneumatizacao supra-orbitaria e a visualizacao do canal da AEA (p<0,001). Conclusao: Em relacao a profundidade da fossa olfatoria, o tipo 11 de Keros foi o mais frequente. Verificou-se assimetria do teto do seio etmoidal, na maioria dos casos relacionada com a inclinacao lateral da lamela lateral da lamina crivosa. Para estudo do trajeto da AEA, a identificacao do forame etmoidal anterior e o sulco etmoidal anterior foram referencias anatomicas confiaveis, presentes em quase 100 por cento dos exames avaliados. Notou-se que a posicao da AEA foi variavel e que na presenca de pneumatizacao supra-orbitaria, o canal da arteria foi observado abaixo da base do cranio em todos os exames, estando mais vulneravel a lesoes
- ItemSomente MetadadadosContribuição para o estudo anátomo-radiológico da origem da artéria ascendens, ramo cólico da artéria ileo-cólica(Universidade Federal de São Paulo (UNIFESP), 1981) Ures, Silvio [UNIFESP]; Prates, José Carlos [UNIFESP]
- ItemAcesso aberto (Open Access)Distribuição comparativa dos glicosaminoglicanos em artérias e veias de diferentes mamíferos(Sociedade Brasileira de Cirurgia Cardiovascular, 1999-10-01) Marquezini, Mônica V.; Dallan, Luís Alberto O.; Toledo, Olga M. S. [UNIFESP]; Pró-Sangue Fundação Hemocentro de São Paulo; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP)A comparative analysis of the glycosaminoglycan distribution in arteries and veins of humans, rats and dogs was realized. The results showed that the glycosaminoglycan distribution of the arteries was similar to that of venous tissues, where dermatan sulfate was the main glycosaminoglycan found. However, the proportion of dermatan sulfate is significantly greater in venous than in arterial tissues, in the three species. The total amount of the glycosaminoglycans was significantly higher in arteries than in veins, and the highest contents were found in the aortas. These increases may be associated with structural differences of the wall of these two types of blood vessels walls. The blood pressure is significantly lower in venous tissues and veins may exhibit less compressibility than arterial. These findings open perspectives for a better understanding of biochemical changes that could be related to the progressive degenerative vascular process, especially in the structural changes that saphenous veins undergo, when used as grafts in myocardial revascularization.
- ItemSomente MetadadadosEstudo do diâmetro arterial após ligadura e secção vascular, em ratos(Universidade Federal de São Paulo (UNIFESP), 2000) Soares, Adriano Leite [UNIFESP]; Nigro, Amaury José Teixeira [UNIFESP]A hemostasia envolve uma serie de diferentes processos cujo grau de contribuicao varia nos tipos de vasos sanguineos e nas diversas condicoes fisiologicas. Este trabalho visa a mensuracao do diametro arterial apos ligadura e seccao vascular. Foram utilizados 50 ratos, Wistar, machos, dos quais se utilizavam duas arterias do mesenterio, que foram distribuidas em: grupo I, arterias submetidas a manipulacao cirurgica, sem ligadura; e Grupo II, arterias ligadas. Cada grupo foi redistribuido em 5 subgrupos de acordo com o tempo de observacao: 1, 6, 12, 24, e 48 horas. Procedia-se a dissecacao do tecido conjuntivo frouxo de um pediculo vascular do mesenterio, sem manipulacao do vaso e da gordura perivasal, sendo, entao, realizada dupla ligadura e seccao vascular. Em cada uma dessas fases, procedia-se a captura de imagem digitalizada, que fora analisada para mensuracao do diametro da arteria. Observou-se uma diminuicao de ate 27,22 por cento, no diametro das arterias, que permaneceu por todo o periodo estudado. Nao ocorreu diferenca estatistica significante entre os diversos locais arteriais medidos. Nas arterias proximas a ligadura, houve um aumento medio de 24,08 por cento no diametro, que durou ate l hora apos a ligadura, mostrando-se mais acentuada proximalmente. Conclui-se que, apos ligadura e seccao vascular, ocorreu diminuicao do diametro arterial nos diversos tempos estudados e de modo semelhante, nos diferentes locais medidos

- ItemAcesso aberto (Open Access)Ligadura com algodão e com grampos de titânio em artérias de cães: estudo experimental em máquina simuladora de pressão(Sociedade Brasileira para o Desenvolvimento da Pesquisa em Cirurgia, 2001-12-01) Soares, Adriano Leite [UNIFESP]; Goldenberg, Saul [UNIFESP]; Novo, Neil Ferreira [UNIFESP]; Lima, Cirilo Antônio De Paula [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)The development of the video laparoscopic surgery has brought the necessity of standardizing the artery ligation with titanium clips in order to minimize operation time. The aim of this study is to investigate and compare the arterial ligation with cotton thread, and also with one, two or three titanium clips. Consequently, eigthy arteries of twenty mongrel s dogs were utilized. Each of the dog had their right and left axillary arteries, as well as the rigth and left femoral arteries used. Those arteries had been previously distributed in 4 groups, being previously chosen by lot and in turns. After arterial dissection and ligation, the arteries were submitted to 100 mmHg and 300 mmHg of pressure, and a pulsation rate of 70 bumps per minute, that was obtained by an arterial pressure simulation machine. There was a liquid escape from 3 arteries, which belonged to the one-titanio-clip group. This escape, that is statistically significant occurred in less than 15 minutes. Furthermore, the results show that the arterial ligation with one titanio clip has a great probability of escaping, contrary to the ligation done with cotton thread, as well as the ones done with two or three titanium clips. Therefore, there is no difference between the ligation with cotton thread and two or three titânio clips, if they are submited to 300 mmHg of pressure and a pulsation rate of 70 bumps per minutes.
- ItemAcesso aberto (Open Access)Pharmacological treatment for buerger's disease(Wiley, 2016) Cacione, Daniel G. [UNIFESP]; Baptista-Silva, Jose C. C. [UNIFESP]; Macedo, Cristiane R. [UNIFESP]Background Buerger's disease (thromboangiitis obliterans) is a non-atherosclerotic, segmental inflammatory pathology that most commonly affects the small and medium sized arteries, veins, and nerves in the upper and lower extremities. The etiology is unknown, but involves hereditary susceptibility, tobacco exposure, immune and coagulation responses. Inmany cases, there is no possibility of revascularization to improve the condition. Pharmacological treatment is an option for patients with severe complications, such as ischaemic ulcers or rest pain. Objectives To assess the effectiveness of any pharmacological agent (intravenous or oral) compared with placebo or any other pharmacological agent in patients with Buerger's disease. Search methods The Cochrane Vascular Trials Search Co-ordinator searched their Specialised Register (last searched in April 2015) and the Cochrane Register of Studies (Issue 3, 2015).

- ItemAcesso aberto (Open Access)Pseudoaneurisma de artéria genicular após cirurgia artroscópica de joelho: Relato de dois casos(Sociedade Brasileira de Ortopedia e Traumatologia, 2010-01-01) Pereira Junior, Edgard Dos Santos [UNIFESP]; Mestriner, Luiz Aurélio [UNIFESP]; Pereira, Edgard Dos Santos; Domingues, Ricardo Perez; Cardoso, Marcos Prado Alves; Universidade Federal de São Paulo (UNIFESP); Universidade de Santo Amaro Departamento de Ortopedia e Traumatologia Grupo de Cirurgia do JoelhoArthroscopy of the knee is a very safe surgical procedure, with relatively few complications. Here we present the cases of two patients submitted to arthroscopic surgery for partial meniscectomy and reconstruction of the anterior cruciate ligament with femoral transverse screw and tibial interference screw that developed a superior lateral genicular artery pseudoaneurysm. Doppler ultrasonography was performed for diagnostic purposes and the patients were treated by direct arterial suture. One patient developed a large haematoma requiring volemic replacement. These cases illustrate a rare, and not always benign vascular complication, in a minimally invasive arthroscopic surgery.
- ItemAcesso aberto (Open Access)Riscos e consequências do uso da técnica transportal na reconstrução do ligamento cruzado anterior: relação entre o túnel femoral, a artéria genicular lateral superior e o epicôndilo lateral do côndilo femoral(Sociedade Brasileira de Ortopedia e Traumatologia, 2012-10-01) Astur, Diego Costa [UNIFESP]; Aleluia, Vinicius; Santos, Ciro Veronese; Arliani, Gustavo Gonçalves [UNIFESP]; Badra, Ricardo; Oliveira, Saulo Gomes; Kaleka, Camila Cohen; Cohen, Moises [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Instituto Cohen; Santa Casa de Misericórdia de São Paulo Faculdade de Ciências MédicasOBJECTIVE: Define a security zone to avoid possibles vascular and ligamentar complications during anterior cruciate ligament reconstruction. METHODS: Arthroscopic reconstruction using the transtibial and transportal technique in cadaver knees was performed followed by dissection and measurement of the distance between the femoral tunnel and the proximal attachment of the lateral collateral ligament and the femoral tunnel and the lateral superior genicular artery. RESULTS: The measure of the analysed distances show us an aproximation between the major branch of the lateral superior genicular artery and the femoral insertion of the colateral lateral ligament and the femoral tunnel during the transportal technique. CONCLUSION: We realize that the use of technical ship it to arthroscopic ACL reconstruction has a higher probability of injury to the lateral geniculate artery and insertion of the lateral collateral ligament, promoting post-surgical complications such as instability of the knee, osteonecrosis of the femoral condyle and ligamentização graft.
