          Abstract

          Abstract Arterial recanalization to restore blood flow in a safe, effective and rapid way is the primary goal in treating hyperacute ischaemic stroke, improving functional outcomes. The clinical benefit of endovascular thrombectomy (EVT) in stroke with large vessel occlusion has been demonstrated and the vascular access route most commonly used for these procedures is the transfemoral approach. When this traditional approach can’t be used, alternative routes, such as the transbrachial ou radial access, may be crucial. In this paper we describe the case of a posterior circulation stroke in a patient with a type A aortic dissection and aortic aneurysm, treated successfully with emergent EVT via the transbrachial access. Given the increasing use of mechanical thrombectomy in acute stroke management and the need to start the treatment as soon as possible it is imperative to optimize all access methods and focus on future studies evaluating alternative vascular approaches.

          Resumo A recanalização arterial para restaurar o fluxo sanguíneo de uma forma segura, eficaz e rápida é o objetivo principal no enfarte isquémico agudo, conseguindo melhorar os resultados clínicos. O benefício clínico da trombectomia endovascular (TEV) no AVC com oclusão de um grande vaso tem sido demonstrado e o acesso vascular mais comummente usado para este procedimento é o transfemoral. Quando este acesso não pode ser usado, métodos alternativos, como a via transbraquial ou radial, podem ser cruciais. Neste artigo descrevemos um caso clínico de um AVC da circulação posterior num paciente com dissecção tipo A e aneurisma da aorta, que foi tratado com sucesso com TEV emergente pela via transbraquial. Tendo em conta o uso crescente da TEV no tratamento do AVC agudo e a necessidade de iniciar o tratamento o mais rapidamente possível, é imperativo otimizar todos os métodos de acesso e focar em estudos futuros que avaliem acessos vasculares alternativos.

          Thrombectomy 6 to 24 Hours after Stroke with a Mismatch between Deficit and Infarct

          The effect of endovascular thrombectomy that is performed more than 6 hours after the onset of ischemic stroke is uncertain. Patients with a clinical deficit that is disproportionately severe relative to the infarct volume may benefit from late thrombectomy.

            Revolution in acute ischaemic stroke care: a practical guide to mechanical thrombectomy

            Rapid, safe and effective arterial recanalisation to restore blood flow and improve functional outcome remains the primary goal of hyperacute ischaemic stroke management. The benefit of intravenous thrombolysis with recombinant tissue-type plasminogen activator for patients with severe stroke due to large artery occlusion is limited; early recanalisation is generally less than 30% for carotid, proximal middle cerebral artery or basilar artery occlusion. Since November 2014, nine positive randomised controlled trials of mechanical thrombectomy for large vessel occlusion in the anterior circulation have led to a revolution in the care of patients with acute ischaemic stroke. Its efficacy is unmatched by any previous therapy in stroke medicine, with a number needed to treat of less than 3 for improved functional outcome. With effectiveness shown beyond any reasonable doubt, the key challenge now is how to implement accessible, safe and effective mechanical thrombectomy services. This review aims to provide neurologists and other stroke physicians with a summary of the evidence base, a discussion of practical aspects of delivering the treatment and future challenges. We aim to give guidance on some of the areas not clearly described in the clinical trials (based on evidence where available, but if not, on our own experience and practice) and highlight areas of uncertainty requiring further research.

              Transradial vs. Transfemoral Approach in Cardiac Catheterization: A Literature Review

              The main objective of this review paper is to study the comparison between transradial and transfemoral approach in catheterization. Transradial and transfemoral are two main approaches which are used as a diagnostic and therapeutic purpose in catheterization. The transradial approach in interventional cardiology is safe, effective, and feasible as compared to the transfemoral approach. The aim of this study is to compare pros and cons of transradial vs. transfemoral approach in catheterization. We conducted this systematic review on the role of transradial vs. transfemoral catheterization. The articles included real human data on interventional approaches. Reviews on these strategies were conducted in PubMed, medical literature analysis and retrieval system online (MEDLINE), Cochrane, Medscape and National Institute of Health. To maintain a high standard of review, studies published in all non-famous journals were excluded. Data collected from the studies have suggested that transradial approach has less bleeding complications, cost effective, decreased hospital mortality rate, and less access site complications as compared to transfemoral approach. However, longer procedural duration and radiation exposure are still concerns regarding transradial approach. The findings of the present study show that transradial approach in catheterization is safe, effective, and feasible as compared to the transfemoral approach. However, duration and radiation exposure are higher in the transradial access. Several studies suggest that the modern approach overweight in benefits with the comparison to the classical approach.
