Carvalho Dias, M; Soares dos Reis, R; Santos, JV; Paiva Nunes, A; Ferreira, P; Maia, B; Fragata, I; Reis, J; Ramos Lopes, J; Cruz, L; Santo, G; Machado, E; Gabriel, D; Felgueiras, R; Dória, H; Carneiro, A; Correia, M; Veloso, LM; Barros, P; Gregório, T; Carvalho, A; Ribeiro, M; Teotónio, P; Neto, L; Pinho e Melo, T; Canhão, P; Filipe, JP; Moreira, G; Azevedo, E; Silva, ML; Campos Costa, E; Oliveira, G; Pereira, L; Neves, L; Rodrigues, M; Marto, JP; Calado, S; Grenho, F; Branco, G; Baptista, T; Rocha, J; Ferreira, C; Pinho, J; Amorim, JM; Araújo, JM; Neiva, RM; Viana, J; Lobo, M; Freitas, A; Tedim Cruz, V; Sargento-Freitas, J; Castro Lopes, JIntroduction: Since the publication of endovascular treatment trials and European Stroke Guidelines, Portugal has re-organized stroke healthcare. The nine centers performing endovascular treatment are not equally distributed within the country, which may lead to differential access to endovascular treatment. Our main aim was to perform a descriptive analysis of the main treatment metrics regarding endovascular treatment in mainland Portugal and its administrative districts. Material and methods: A retrospective national multicentric cohort study was conducted, including all ischemic stroke patients treated with endovascular treatment in mainland Portugal over two years (July 2015 to June 2017). All endovascular treatment centers contributed to an anonymized database. Demographic, stroke-related and procedure-related variables were collected. Crude endovascular treatment rates were calculated per 100 000 inhabitants for mainland Portugal, and each district and endovascular treatment standardized ratios (indirect age-sex standardization) were also calculated. Patient time metrics were computed as the median time between stroke onset, first-door, and puncture. Results: A total of 1625 endovascular treatment procedures were registered. The endovascular treatment rate was 8.27/100 000 inhabitants/year. We found regional heterogeneity in endovascular treatment rates (1.58 to 16.53/100 000/year), with higher rates in districts closer to endovascular treatment centers. When analyzed by district, the median time from stroke onset to puncture ranged from 212 to 432 minutes, reflecting regional heterogeneity. Discussion: Overall endovascular treatment rates and procedural times in Portugal are comparable to other international registries. We found geographic heterogeneity, with lower endovascular treatment rates and longer onset-to-puncture time in southern and inner regions. Conclusion: The overall national rate of EVT in the first two years after the organization of EVT-capable centers is one of the highest among European countries, however, significant regional disparities were documented. Moreover, stroke-onset-to-first-door times and in-hospital procedural times in the EVT centers were comparable to those reported in the randomized controlled trials performed in high-volume tertiary hospitals.
- Um Novo Factor de Risco para Endocardite InfecciosaPublication . Toste, A; Ferreira, ML; Oliveira, JA; Feliciano, J; Conceição, J; Baquero, L; Freitas, A; Freitas, P; Fragata, J; Cruz Ferreira, RA implantação de piercings corporais tem sido uma prática cada vez mais comum nas últimas décadas, sobretudo entre os mais jovens. No entanto, não se trata de um procedimento inócuo, podendo apresentar complicações tão graves como a endocardite infecciosa, que pode surgir em indivíduos com ou sem cardiopatia de base. Neste artigo relatamos o caso de uma endocardite pós piercing numa jovem com pacemaker definitivo, tendo havido necessidade de intervenção cirúrgica. Fazemos igualmente uma revisão dos casos de endocardite pós piercing descritos na literatura. Agora que as recomendações da American Heart Association para a profilaxia de endocardite infecciosa estão mais restritas, discutimos a necessidade de inclusão dos piercings corporais nos procedimentos a merecerem terapêutica profiláctica nos indivíduos de alto risco.
- Pseudoaneurisma do Ventrículo Esquerdo com Duplo Orifício de Entrada após Enfarte Agudo do MiocárdioPublication . Baptista, S; Freitas, A; Ferreira, D; Silva Cunha, P; Roquette, J; Ferreira, RDoente do sexo feminino, 78 anos de idade, internada previamente por EAM combinado. A evolução clínica subsequente decorreu sem complicações, tendo alta ao 10.º dia. Cerca de 12 horas depois foi readmitida no Serviço de Urgência, por dor retrosternal prolongada, hipotensa e prostrada. O ECG (Fig. 1) mostrou re-elevação do segmento ST nas derivações anteriores e inferiores, sendo admitida na Unidade de Cuidados Intensivos com o diagnóstico de provável re-enfarte. O Ecocardiograma realizado na admissão revelou função sistólica global comprometida, sendo possível definir um volumoso espaço anecogénico no ápex do ventrículo esquerdo (VE), com solução de continuidade na transição do terço médio/apical da parede inferior (Fig. 2) e uma segunda solução de continuidade na transição do terço médio/apical da parede lateral do VE (Fig. 3). Em ambos os orifícios foi confirmada a presença de fluxo bidireccional por Doppler Pulsado e Cor (Fig. 2), sugerindo a presença de um pseudoaneurisma do VE com duplo orifício de entrada. A doente foi transferida para um centro cirúrgico, onde, após confirmação intra-operatória do pseudoaneurisma com duplo orifício, foi submetida a encerramento do colo com patch de teflon. Teve alta estável, sendo seguida em consulta de Cardiologia desde há cerca de 16 meses, sem eventos.
- Trombos Intraventriculares com Embolização Sistémica: a Propósito de Dois Casos ClínicosPublication . Magno, P; Freitas, A; Cunha, P; Loureiro, J; Fragata, J; Ferreira, RA formação de trombos intraventriculares é um complicação frequente nos doentes com miocardiopatia dilatada e enfarte agudo do miocárdio, sendo o risco de embolização sistémica muito variável em função da patologia subjacente e características subjacentes dos trombos. Os autores descrevem dois casos clínicos relativos a dois doentes internados no mesmo dia com trombos intraventriculares, volumosos, protuberantes e muito móveis, no contexto de miocardiopatia dilatada e enfarte agudo do miocárdio, que embolizaram para os membros inferiores. Salientam a importância da ecocardiografia no diagnóstico, caracterização morfológica inicial e controlo evolutivo dos trombos intraventriculares, aspectos fundamentais na avaliação do risco embólico. Na ausência de recomendações específicas quanto às opções terapêuticas – anticoagulação, trombólise ou remoção cirúrgica, os autores sublinham a necessidade de avaliação individualizada, «caso a caso», tendo em conta o risco embólico, hemorrágico, e cirúrgico.
- Vascular Training Does Matter in the Outcomes of Saphenous High Ligation and StrippingPublication . Castro-Ferreira, R; Quelhas, MJ; Freitas, A; Vidoedo, J; Alves Silva, E; Marinho, A; Abreu, R; Coelho, A; Gonçalves Dias, P; Moreira Sampaio, SObjective: Varicose vein (VV) surgery is frequently performed by surgeons without formal vascular training. We aimed to compare the outcomes of the procedure based on the background of the surgeon. Methods: All patients registered with VV surgery between 2004 and 2016 in Portuguese public hospitals were included in the study. Intrahospital outcomes were assessed from this administrative database. A random multicenter sample of 315 patients submitted to saphenous high ligation and stripping (175 patients from six vascular surgery departments and 140 patients from five general surgery divisions) were further queried over the phone, whereby additional nonregistered outcomes were evaluated: preoperative venous ultrasound, impact on quality of life by the 14-item Chronic Venous Insufficiency Quality of Life Questionnaire, visual analogue scale evaluation (score of 1 to 5) of the aesthetic results and general satisfaction, work absence days, and time to return to physical activities. Results: In 13 years, there were 153,382 patients submitted to VV surgery. Of these, 49% were operated on by general surgeons and 40% by vascular surgeons; in 11%, it was not possible to identify the specialty performing the operation. Twenty-three deaths were registered (no differences between groups). In the general surgery group, 14% of patients were hospitalized for more than one night compared with 3% in the vascular group (P < .001). Reintervention rate during the period analyzed was significantly higher in the general surgery group (13.5% vs 8.2%; P < .001). Rate of outpatient surgery was higher in the vascular surgery group (60% vs 36%; P < .001). Phone query revealed similar overall satisfaction and improvement in quality of life in both groups (4.2 vs 4.0 [P = .275] and 35% vs 36% [P = .745], respectively). However, patients operated on by general surgeons reported worse surgical scars (2.8 vs 2.1; P = .007), higher number of residual VVs (2.4 vs 1.7; P = .006), and higher number of days absent from work (40 vs 27 days; P = .005) and took longer to resume physical activities (60 vs 41 days; P = .001). Conclusions: Despite that the majority of VV surgery in Portugal is executed by general surgeons, this study highlights important advantages when it is performed by surgeons with vascular training.
