Cholesteryl hemiazelate identified in CVD patients causes in vitro and in vivo ...
Domingues, Neuza S.; Gaifem, Joana; Matthiesen, Rune; Saraiva, Diana P.; Bento, Luís; Marques, André R. A.; Soares, Maria I. L.; Sampaio, JulioOxidation of PUFAs in LDLs trapped in the arterial intima plays a critical role in atherosclerosis. Though there have been many studies on the atherogenicity of oxidized derivatives of PUFA-esters of cholesterol, the effects of cholesteryl hemiesters (ChEs), the oxidation end products of these esters, have not been studied. Through lipidomics analyses, we identified and quantified two ChE types in the plasma of...
HYBRID SURGERY ON THORACIC ANEURISM RUPTURE: AN EFFECTIVE ALTERNATIVE IN A CASE...
Pinto, Vanda; Ministro, Augusto; Henriques, Mickael; Rodrigues, Marta; Melo, Ryan; Silva, Emanuel; Pedro, Luís MendesEndovascular treatment of descending thoracic aortic aneurysms (DTAA) is associated with low rates of morbimortality and is currently the first line of therapeutic intervention. Endoleaks are a well-known complication of this technique, with the consensus that the identification of type I endoleak implies its prompt correction. We present the case of a patient who underwent TEVAR for the treatment of DTAA, with...
OFF-THE-SHELF COOK® T-BRANCH® BRANCHED ENDOPROSTHESIS DEPLOYMENT: TECHNICAL ASP...
Lopes, Alice Cabral; Melo, Ryan Gouveia; Amorim, Pedro; Sobrinho, Gonçalo; Fernandes e Fernandes, Ruy; Pedro, Luís MendesIntroduction: Off-the-shelf multi-branched stent grafts, such as Cook t-Branch®, emerged as an alternative for the prompt treatment of thoracoabdominal aneurysms (ATA). Objective/Technique: In our institution, the use of the Cook T-Branch® stent graft has been carried out in urgent cases and in some elective cases with favorable anatomy and in which it is not advisable to wait for the production of a custom-mad...
3D PRINTING OF RENAL ARTERY ANEURYSMS. A NEW IMAGING METHOD IN THE THERAPEUTIC ...
Bartikian, Michael; Sobrinho, Gonçalo; Lopes, Alice; Gomes, Miguel; Pedro, Luís MendesCase report of a female patient with a right renal artery aneurysm with involvement of distal branches. The angio-CT was diagnostic and showed the anatomy. The arteriogram showed the medial fibrodysplasia pattern but did not add to the tridimensional assessment of the branches. Angio-CT 3D printing allowed for better understanding of the anatomy, valuable for surgical decision and planning which consisted in ex...
Os custos da aterosclerose em Portugal
Costa, João; Alarcão, Joana; Amaral‐Silva, Alexandre; Araújo, Francisco; Ascenção, Raquel; Caldeira, Daniel; Cardoso, Marta Ferreira; Correia, ManuelIntroduction and objectives: Cardiovascular disease is the leading cause of death in Portugal and atherosclerosis is the most common underlying pathophysiological process. The aim of this study was to quantify the economic impact of atherosclerosis in Portugal by estimating disease‐related costs. Methods: Costs were estimated based on a prevalence approach and following a societal perspective. Three national ep...
VASCULAR GRAFT INFECTIONS — A HISTORICAL REVIEW
Gouveia e Melo, Ryan; Santos, Carla Mimoso; Fernandes e Fernandes, Ruy; Garrido, Pedro; Pedro, Luís MendesVascular graft infections are still to date a complex medical challenge. The evolution of the hospital flora and development of the vascular surgery field has led to a change in the reality of these infections, making it important to know their current microbiological context in order to provide better care. These infections depend on endogenous and exogenous factors and vary according to the timing of infectio...
EVAS DEVICE EXPLANTATION IN A SECONDARY RUPTURE OF AN ABDOMINAL AORTIC ANEURYSM
Lopes, Alice; Soares, Tony; Amorim, Pedro; Sobrinho, Gonçalo; Pedro, Luís Mendes Endovascular aneurysm sealing (EVAS) was a relatively new concept that aimed to reduce the incidence of complications after endovascular aneurysm exclusion. However, EVAS device was recently recalled from market due to high risk of graft failure beyond two years after implantation(1,2). The aim of this paper is to report a case of a post-EVAS ruptured abdominal aortic aneurysm. A 72 year-old-man underwent...
ADAPTATIONS IN THE VASCULAR SURGERY DEPARTMENT OF THE CHULN DURING THE COVID-19...
Duarte, António; Melo, Ryan; Lopes, Alice; Rato, João; Rodrigues, Marta; Henriques, Mickael; Gomes, Miguel; Pinto, Vanda; Ribeiro, Karla; Silva, EmanuelWith the onset of the SARS-CoV-2 pandemic in early 2020, health services and personnel adapted their resources to mitigate and control the outbreak. These needs inevitably led to adaptations in most medical and surgical departments, including in our Vascular Surgery department. As we are facing a second outbreak of this pandemic, with unpredictable outcomes and repercussions in health services, it is crucial to...

Transferido para o nosso hospital após colocação de catéter venoso central na veia jugular interna esquerda a qual foi complicada de punção transfixiva e cateterização acidental da artéria carótida primitiva ipsilateral com progressão para o arco aórtico (Figura ...
TREATMENT OF AORTIC DISSECTIONS USING A COMBINATION OF THE STABILISE AND CERAB ...
Gouveia e Melo, Ryan; Fernandes e Fernandes, Ruy; Garrido, Pedro; Lopes, Alice; Rato, João Pedro; Leitão, João; Pedro, Luís MendesIntroduction: Endovascular treatment of type B aortic dissection has focused on the covering of the proximal entry tear. However, recently, concern has emerged regarding the distal aortic remodeling and new techniques such as the Stent-Assisted Balloon-Induced Intimal Disruption and Relamination (STABILISE) technique have gained more acceptance. We describe a technical note regarding the combination of the STAB...
