Endovascular treatment of the ascending aorta is feasible. We had 4 good mid-term results in 7 patients who had presented with penetrating ulcers or aneurysm formation. Acute dissections seem to be more unstable, and additional research is mandatory.
O pseudo-aneurisma de ventrículo esquerdo após infarto agudo do miocárdio é entidade rara. Quando diagnosticado, deverá ser operado logo que possível, devido ao risco aumentado de rotura de sua parede. No período de novembro de 1992 a junho de 1995, foram encaminhados ao nosso Serviço 3 pacientes com suspeita clínica de pseudo-aneurisma de ventrículo esquerdo (VE), com sinais clínicos, radiológicos, ecocardiográficos e angiográficos característicos da lesão. O objetivo do trabalho é discutir o diagnóstico, a indicação cirúrgica, as técnicas e táticas empregadas, as complicações e os resultados cirúrgicos. Todos os pacientes foram submetidos ao ecodopplercardiograma transtorácico, que foi suficiente para o diagnóstico. Após propedêutica adequada, com realização de angiografia e ventriculografia, os pacientes foram submetidos à correção utilização de pericárdio bovino. Um dos pacientes apresentava comunicação interventricular (CIV), que foi corrigida no mesmo ato cirúrgico. Os pacientes receberam alta em bom estado geral, com controle ecocardiográfico evidenciando a correção do pseudo-aneurisma. The postinfarction pseudoaneurysm of the left ventricle is a rare entity. When diagnosed it surgery is necessary, as soon as possible, due to the increased risk of rupture of its wall. During November 1992 to June 1995 three patients were sent to our Hospital with a clinical diagnosis of pseudoaneurysm of the left ventricle. They showed clinical, radiological, echocardiographic and angiographic signs characteristic of this pathology. Our objective is to discuss the diagnosis, surgical indication techniques, complications and surgical results. All patients were submitted to transthoracic echodopplercardiogram and it was enough for the diagnosis. After the realization of angiography and ventriculography the patients were submitted to surgery to correct the pseudoaneurysm using bovine pericardium. One patient showed an interventricular communication that was also corrected during the same operation. All patients were discharged in good condition with echocardiogram showing complete correction of the pseudoaneurysm
The capital structure has been studied consistently since 1952. The volatility of the structures of capital is recent, where the static trade-off theory is questioned, DeAngelo & Roll (2015). It followed this idea, and not only the study of determinants between companies. The aim of this article is to answer if the Brazilian companies are unstable in terms of structure capital and not an exception, and subsequently identify the impact of the volatility of capital structures, profitability, size, sector of activity, etc. 625 non-financial companies were analyzed, from 2003 to 2016, listed on the Brazilian Stock Exchange with models dynamic and static. The results conclude that the capital structures in Brazil are volatile, and that there was not profitability in the companies, even though they had increased their debts.
Pseudoaneurysms of the internal carotid artery are uncommon and normally secondary to trauma of the cervical region. Frequently it is the throat and neck doctor who evaluates these patients. We report on the case of a 15-year-old patient with active bleeding via the oral cavity, headache, and later hematoma in the cervical region. Arteriography demonstrated a pseudoaneurysm of the internal carotid artery. Angiography demonstrated successful embolization after the placement of coils and thus endovascular procedures are an alternative treatment for pseudoaneurysms of the internal carotid arteries in adolescents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
