    Apresentação Atípica de Hematoma Intramural da Aorta Ascendente comTratamento Conservador
    (Sociedade Brasileira de Hemodinâmica e Cardiologia Intervencionista - SBHCI, 2014-09-01) Alves, Claudia Maria Rodrigues [UNIFESP]; Gomes Junior, Manuel Pereira Marques; Faraco, Ricardo Peressoni; Sawabini, Tatiana; Dias Filho, Paulo Cézar Ferraz Dias; Leão Filho, Hilton Muniz; Universidade Federal de São Paulo (UNIFESP); Hospital do Coração Associação do Sanatório Sírio
    O hematoma intramural aórtico é uma doença grave, secundária a sangramento da vasa vasorum e/ou microúlceras aórticas, sem comunicação com aluz verdadeira do vaso. Seu achado ocasional, na ausência de sintomas ou traumaaórtico, é bastante raro. Neste relato, paciente assintomática, com comprometimentoda aorta ascendente e arco, foi mantida em tratamento clínico, a despeito darecomendações predominantes para correção cirúrgica em lesões classificadas como tipoA de Stanford. Discutimos aspectos pertinentes à caracterização da lesão nodiferentes exames de imagem, identificação de critérios de alto risco anatômico econdução do caso. A evolução em 7 meses foi satisfatória.

    Interrupção do arco aórtico tipo B em uma paciente com síndrome de olho de gato
    (Sociedade Brasileira de Cardiologia - SBC, 2009-05-01) Belangero, Sintia Iole [UNIFESP]; Bellucco, Fernanda Teixeira da Silva [UNIFESP]; Cernach, Mirlene Cecilia Soares Pinho [UNIFESP]; Hacker, April M.; Emanuel, Beverly S.; Melaragno, Maria Isabel [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); University of Pennsylvania Children´s Hospital of Philadelphia
    We report a patient with cat eye syndrome and interrupted aortic arch type B, a typical finding in the 22q11.2 deletion syndrome. Chromosomal analysis and fluorescent in situ hybridization (FISH) showed a supernumerary bisatellited isodicentric marker chromosome derived from chromosome 22. The segment from 22pter to 22q11.2 in the supernumerary chromosome found in our patient does not overlap with the region deleted in patients with the 22q11.2 deletion syndrome. However, the finding of an interrupted aortic arch type B is unusual in CES, although it is a frequent heart defect in the 22q11 deletion syndrome.

    Tratamento de aneurismas da parte torácica da aorta pela introdução de stents sob visão endoscópica
    (Sociedade Brasileira de Cirurgia Cardiovascular, 1998-01-01) Fonseca, José Honório de Almeida Palma da [UNIFESP]; Geisthõvel, Nikolaus [UNIFESP]; Brasil, Luiz Antonio [UNIFESP]; Ferrari, Angelo Paulo [UNIFESP]; Carvalho, Antonio Carlos [UNIFESP]; Gomes, Walter José [UNIFESP]; Buffolo, Enio [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    This is a case report of a patient with two saccular aneurysms in the thoracic descending aorta. Treatment consisted of the positioning, through an opening in the aortic arch under deep hipothermia and total circulatory arrest, of two auto expandable stents, guided an Olympus endoscope. The bloodless field made possible the identification of the main thoracic and abdominal aortic branches facilitating the positioning and expansion of both stents. Immediate postoperative recovery was excellent. This is a previously unreported way of placing stents and could open a new perspective in the treatment of thoraco, abdominal and thoracic abdominal aortic aneurysms.

    Tratamento endovascular nos aneurismas verdadeiros e na dissecção aórtica do tipo B: fase intra-hospitalar, seguimento de médio prazo e uma reflexão sobre seleção de pacientes
    (Sociedade Brasileira de Hemodinâmica e Cardiologia Intervencionista - SBHCI, 2009-01-01) Alves, Claudia Maria Rodrigues [UNIFESP]; Fonseca, José Honório de Almeida Palma da [UNIFESP]; Souza, José Augusto Marcondes de [UNIFESP]; Kim, Hyung Chun [UNIFESP]; Esher, Guilherme [UNIFESP]; Buffolo, Enio [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    BACKGROUND: Endovascular treatment of thoracic aortic diseases is a well established procedure although late results and differences among demographic groups are unknown. METHOD: From December/1996 to December/2004, 92 patients with true aneurysms or penetrating ulcers (G1) and 130 patients with type B dissection or intramural hematoma (G2) were submitted to primary or complementary endovascular treatment. Clinical success was defined as sustained technical success without death or surgical conversion. Late failure was defined as death of any cause, surgical conversion or re-intervention. RESULTS: G1 mean age was 65 ± 11 years and 56 ± 11 years in G2 (P < 0.0001). A high frequency of previous stroke was observed in G1 (8.7% vs. 0; P = 0.0007). Clinical success was observed in 71% in G1 and 84% in G2 (P = 0.02) with higher in-hospital death rates in G1 (14% vs. 4.6%; P = 0.01). Neurologic complications were similar (6.5% vs. 3%, respectively; P = 0.32), with a mild prevalence of paraplegia in G1 (3.2% vs. 0.8%; P = 0.3). Late failure rates of 60% were observed in G1 and 43% in G2 (P = 0.09) at 33 ± 27 months of follow-up. CONCLUSIONS: Endovascular treatment in patients with true aneurysms may be slightly inferior to those achieved in patients with type B dissection. This might be due to demographic differences between groups and technical difficulties related to aortic anatomy. The knowledge and understanding of these peculiarities enables better patient selection for the procedure resulting in decreased mortality rates.

    Utilização de endoprótese autoexpansível (stent) posicionada na aorta torácica do cão
    (Sociedade Brasileira de Cirurgia Cardiovascular, 1997-07-01) Paula, Ivan Antônio Machado de [UNIFESP]; Fonseca, José Honório de Almeida Palma da [UNIFESP]; Branco, João Nelson Rodrigues [UNIFESP]; Goldenberg, Saul [UNIFESP]; Souza, Marcia Marcelino de [UNIFESP]; Geisthovel, Nikolaus [UNIFESP]; Buffolo, Enio [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    We present 5 dogs who underwent treatment with an auto-expandable Dacron-covered stent in the thoracic aorta. The catheter with stents was deployed through the abdominal aorta. The procedure was performed under total anesthesia and full heparinization. A perfect integration of the stent and thoracic aorta was observed on histological examination. We believe that utilization is an improvement in relation to the elephant trunk technique and that it should contribute to improve surgical results in type B dissection.
