Spinal cord ischemia in endovascular repair of thoracoabdominal and complex abd...
Magalhães,Tiago; Melo,Ryan Gouveia e; Fernandes,Ruy Fernandes e; Asseiro,Joana; Lopes,Alice; Rodrigues,Marta; Pedro,Luís MendesAbstract Introduction: Spinal cord ischemia (SCI) is an uncommon but one of the most terrifying complications associated with the treatment of extensive aortic aneurysms. Its pathophysiology, risk factors, and event characteristics must be clarified. This study aimed to perform a descriptive analysis of the cases of SCI after complex aortic repair at our center and to understand which factors contributed to the...
Sex-related differences in patients with acute aortic syndromes
Ferreira,Adriana M.; Lopes,Alice; Rodrigues,Marta; Pedro,Luís MendesAbstract Introduction: Heterogeneity in the epidemiology, management, and in-hospital outcomes of patients with acute aortic syndromes can be found among male and female populations. This study aims to analyze sex-related differences in a cohort of patients treated in a tertiary university center. Methods: All patients admitted with acute aortic syndromes between January 2012 and January 2023 were retrospective...
Practice changes in renal artery stenting after the CORAL trial
Duarte,António; Moutinho,Mariana; Lopes,Alice; Sobrinho,Gonçalo; Pedro,Luís MendesAbstract Introduction: Renal angioplasty emerged as an alternative for renal artery stenosis (RAS). In 2009 and 2014, two clinical trials (ASTRAL and CORAL) led to a paradigm shift in renovascular disease. Neither showed a clear benefit over best medical treatment, although there were methodological flaws. This study aims to evaluate the impact of these trials in clinical practice. Methods: We designed a retros...
Epidemiology of Aortic Dissections - Understanding the Aortic Catastrophe
Melo,Ryan Gouveia e; Fernandes,Ruy Fernandes e; Caldeira,Daniel; Lopes,Alice; Henriques,Mickael; Magalhães,Tiago; Pedro,Luís MendesAbstract Acute aortic dissections are unpredictable aortic catastrophes. Although significant recent improvements have been accomplished in the treatment and management of aortic dissections, a significant amount is still not fully understood regarding this deadly condition. Comprehension of aortic dissections is especially important due to the impact of the disease, since a lot of patients die before reaching ...
Time goals in ruptured abdominal aortic aneurysm - the experience of a tertiary...
Rato,João Pedro; Amorim,Pedro; Lopes,Alice; Melo,Ryan Gouveia e; Moutinho,Mariana; Pedro,Luís MendesAbstract Introduction: Guidelines state that ruptured abdominal aortic aneurysms should be treated shortly after the diagnosis and ideally within 90 minutes. The main aim of this study is to assess the referral pattern of our centre regarding the intervals between the diagnosis of ruptured AAA and the surgical repair, considering the geographical referral areas of our hospital. Methods: We conducted an observat...
Case report of suspected Takayasu arteritis manifesting as chronic mesenteric i...
Duarte,António; Lopes,Alice; Sobrinho,Gonçalo; Pedro,Luís MendesAbstract Introduction: Chronic intestinal ischemia accounts for approximately 1:1,000,000 admissions in some epidemiological studies. This condition usually affects individuals with known atherosclerotic lesion in other territories. Although typically found in female patients in their seventh decade of life with established arterial disease, chronic intestinal ischemia may manifest itself in younger patients. I...
Out of hospital cardiac arrests and aortic dissection
Melo,Ryan Gouveia e; Fernandes,Ruy Fernandes e; Caldeira,Daniel; Lopes,Alice; Henriques,Mickael; Magalhães,Tiago; Pedro,Luís MendesAbstract Introduction: Out of Hospital Cardiac Arrest (OHCA) is one of the main causes of death worldwide. Most of the intrinsic causes of OHCA tend to be of cardiac origin, however, non-cardiac etiologies such as acute aortic dissection (AAD) may be more common than previously thought. The aim of this focused review is to summarize current knowledge on the association between OHCA and AAD. Methods: A systemati...
A impressão 3d dos aneurismas das artérias renais. Um novo método de imagem par...
Bartikian,Michael; Sobrinho,Gonçalo; Lopes,Alice; Gomes,Miguel; Pedro,Luís MendesResumo Caso clínico de uma mulher com aneurisma da artéria renal direita com envolvimento dos 3 ramos distais. A angio-TC permitiu o diagnóstico e a caracterização morfológica. A arteriografia mostrou o padrão de fibrodisplasia da média mas foi pouco útil na definição tridimensional dos ramos. A impressão de um modelo 3D baseado na angio-TC, permitiu uma melhor definição da anatomia o que ajudou na decisão e pl...
Técnica de double kissing (DK) crush para o tratamento de doença arterial perif...
Lopes,Alice; Amorim,Pedro; Vieira,João; Albino,PereiraResumo Introdução: O tratamento de lesões arteriais complexas com oclusões longas e envolvimento da bifurcação das artérias tibiais permanece um desafio técnico na área endovascular que muitas vezes culmina com a escolha de uma alternativa cirúrgica convencional. Dadas as semelhanças de calibre arterial e de material necessário, a adaptação de técnicas utilizadas nas lesões de bifurcações na circulação coronári...
Endoleak tipo IIIB: a propósito de um caso clínico
Gomes,Miguel Lemos; Lopes,Alice; Sobrinho,Gonçalo; Ribeiro,Karla; Leitão,João; Pedro,Luís MendesOs endoleaks (EL) do tipo IIIb resultam de um defeito no tecido da endoprótese e são uma complicação tardia rara, mas grave, inerente à correção endovascular de aneurismas da aorta (EVAR). Neste trabalho, os autores descrevem o caso de um homem de 81 anos submetido em 2013 a EVAR, devido a aneurisma da aorta abdominal (AAA) de 87mm. O procedimento decorreu sem intercorrências, assim como os primeiros dois anos ...
