Open repair of type IV thoracoabdominal aortic aneurysms: a real-world experien...
Romão Rodrigues, Marta; Magalhães, Tiago; Gouveia e Melo, Ryan; Silvestre, Luis; Fernandes e Fernandes, Ruy; Silva, Emanuel; Amorim, PedroINTRODUCTION: Currently, type IV thoracoabdominal aortic aneurysms (TAAA-IV) are treated primarily by endovascular repair. Despite the increased morbidity, there is still a role for open surgery in selected patients. This paper aims to present a descriptive analysis and outcome evaluation of open repair for TAAA-IV in our institution, where endovascular repair is generally the first-line treatment option. METHO...
Early impairment of paracrine and phenotypic features in resident cardiac mesen...
Picchio, Vittorio; Gaetani, Roberto; Pagano, Francesca; Derevyanchuk, Yuriy; Pagliarosi, Olivia; Floris, Erica; Cozzolino, Claudia; Bernava, GiacomoRadiotherapy-induced cardiac toxicity and consequent diseases still represent potential severe late complications for many cancer survivors who undergo therapeutic thoracic irradiation. We aimed to assess the phenotypic and paracrine features of resident cardiac mesenchymal stromal cells (CMSCs) at early follow-up after the end of thoracic irradiation of the heart as an early sign and/or mechanism of cardiac to...
The evolution of management of type B aortic dissection in a series of 100 cons...
Lopes, Alice; Pedro, Luís M; Melo, Ryan; Moutinho, Mariana; Sobrinho, Gonçalo; Amorim, Pedro; Silvestre, Luís; Fernandes E Fernandes, RuyIntroduction and objectives: Management of aortic dissection is rapidly evolving. The present study aims to assess paradigm shifts in type B aortic dissection (TBAD) treatment modalities and their outcomes according to clinical presentation and type of treatment. We also aim to assess the impact of endovascular technology in TBAD management in order to define organizational strategies to provide an integrated c...
Molecular changes in cardiac tissue as a new marker to predict cardiac dysfunct...
Ribeiro, Sónia; Simões, Ana Rita; Rocha, Filipe; Vala, Inês Sofia; Pinto, Ana Teresa; Ministro, Augusto; Poli, Maria Esmeralda; Diegues, Isabel MariaThe contribution of radiotherapy, per se, to late cardiotoxicity remains controversial. To clarify its impact on the development of early cardiac dysfunction, we developed an experimental model in which the hearts of rats were exposed, in a fractionated plan, to clinically relevant doses of ionizing radiation for oncological patients that undergo thoracic radiotherapy. Rat hearts were exposed to daily doses of ...
POST-DISSECTION THORACO-ABDOMINAL ANEURYSMS: RESULTS OF OPEN AND ENDOVASCULAR R...
Gouveia e Melo, Ryan; Campos, Jorge; Garrido, Pedro; Lopes, Alice; Fernandes e Fernandes, Ruy; Silvestre, Luís; Sobrinho, Gonçalo; Ministro, AugustoIntroduction/Objectives: Repair of post-dissection thoraco-abdominal aortic aneurysms (PD-TAAA) is a complex challenge. Choosing the correct approach to manage these aneurysms is not straightforward as both open and endovascular strategies are valid. Our aim was to analyze and compare the results of PD-TAAA treated by endovascular or open surgery. Methods: A seven-year (January-2013 and May-2020) single-center ...
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...
PROXIMAL EXTENSION OF JUXTA-RENAL AORTIC THROMBOSIS: AN UNDERESTIMATED COMPLICA...
Henriques, Mickael; Ministro, Augusto; Silva, Emanuel; Pinto, Vanda; Rato, João; Mendes Pedro, LuísAorto-iliac occlusive disease sometimes extends proximally with involvement of the renal arteries and visceral aorta, with loss of renal functional mass and intestinal ischemia. In this article we report the case of a patient presenting with progressive disabling intermittent claudication caused by chronic juxtarenal aortic thrombosis with proximal progression and involvement of the left renal artery, with a fu...
ENDOVASCULAR MANAGEMENT OF TRANSPLANT RENAL ARTERY STENOSIS: EARLY AND MID-TERM...
Pinto, Vanda; Lopez, Noélia; Cardoso, Ana; Henriques, Mickael; Silva, Emanuel; Silvestre, Luís; Baptista, Lucas; Guerra, José; Mendes Pedro, LuísOBJECTIVE: Renal graft dysfunction or worsened hypertension in renal transplanted patients may be a manifestation of graft hypoperfusion due to transplant renal artery stenosis (TRAS) or stenosis of iliac arteries proximal to renal transplant (pseudo-TRAS). Endovascular management of TRAS has been increasingly used to preserve renal graft function. With this study, we aim to evaluate the impact of endovascular ...
A catastrophic seronegative anti-phospholipid syndrome: case and literature review
Pinto, Vanda; Ministro, Augusto; Carreira, Nuno; Cardoso, Ana; Gonçalves, Catarina Sousa; Henriques, Mickael; Rato, João; Silva, Emanuel; Pedro, Luís MBackground: Antiphospholipid Syndrome (APS) is a multisystemic autoimmune disease characterized by arterial and venous thrombosis and / or obstetric morbidity in the presence of at least one circulating anti-phospholipid antibody. The spectrum of vascular events varies from deep venous thrombosis to catastrophic APS, a rare form characterized by acute multiorgan thrombosis and high mortality. Case report: We pr...
LIVING DONOR RENAL TRANSPLANTATION — A COMPLEX VASCULAR CASE
Pinto, Vanda; Ministro, Augusto; Silvestre, Luís; Mendes Pedro, Luís; Lopez, Noélia; Guerra, José; Baptista, LucasIntroduction: The presence of multiple renal vessels is frequent in the general population and, when present in a donor, increases the complexity of renal transplantation surgery, increasing the risk of complications. Although transplantation of cadaver donor grafts with these characteristics is accepted, the same procedure in living donor remains controversial. The objective of this work is to present th...
