Nowadays, catheter direct thrombolysis (CDT) is commonly used as an alternative to surgery in immediate management of the ALI and may offer certain advantages over surgery in appropriately selected patients.  Objective:  To evaluate CDT data for the treatment of acute ischaemia in lower extremity in different aetiologies.  Materials and methods:  All consecutive patients who underwent CDT for acute limb ischaemia in our vascular surgery department, between 1 January 2011 to 31 August 2017 were identified and reviewed. Outcome measures included primary patency at 30 days and one year, haemorrhagic complications, major amputation and mortality.  Results:  In total, 128 limbs from 106 patients were included. The median follow-up was 14 months [range: 6-31 months]. The aetiologies of ischaemia included in the study were native artery thrombosis, PTFE and GSV bypass thrombosis, intra-stent thrombosis, popliteal aneurysm and entrapment thrombosis and arterial embolism. The Stages of ALI according to the Rutherford classification were 12,5% in class I, 77,3% in class IIa and 10,2% in class IIb. Primary patency rates were 71.3% and 47.8% at one and three years, respectively. The requirement for re-intervention was 27.6% in the native artery thrombosis group, 65.2% in the PTFE graft thrombosis group, and 18.2% in the intra-stent thrombosis group. No re-interventions were verified for popliteal aneurysm or arterial embolism aetiologies. The overall amputation free survival was 83.3% at 27 months, and the cumulative incidence of death was 10.1% at 32 months. Complications occurred in 40 interventions (31.3%); the majority comprised minor bleeding from the access site, and one death due to haemorrhagic stroke.  Conclusions:  CDT although associated with an increased risk of bleeding complications, it is a feasible and safe therapy, with clinical outcomes that may reduce the need for open surgical treatment in many patients. Our findings support this therapeutic approach as a valid option in ALI, in different aetiologies.]]></p></abstract>
<abstract abstract-type="short" xml:lang="pt"><p><![CDATA[Resumo  Introdução:  Ao longo das últimas décadas houve uma evolução nas opções de tratamento da isquemia aguda de membro (IAM). Hoje em dia, a trombólise dirigida por cateter (TDC) é por vezes utilizada como alternativa à cirurgia no tratamento da IAM e pode oferecer algumas vantagens em relação à cirurgia convencional em pacientes devidamente seleccionados.  Objectivo:  Avaliar os dados relativos à TDC para o tratamento da isquemia aguda de membro em diferentes etiologias.  Materiais e métodos:  Foram consecutivamente analisados todos os pacientes submetidos a TDC na isquemia aguda de membro no nosso serviço de cirurgia vascular, entre 1 de Janeiro de 2011 e 31 de Agosto de 2017. Os resultados incluíram a patência primária aos 30 dias e um ano, complicações hemorrágicas, amputação major e mortalidade.  Resultados:  No total foram incluídos 128 membros de 106 pacientes. O seguimento mediano foi de 14 meses [6-31 meses]. As etiologias de isquemia incluídas no estudo foram trombose de artérias nativas, trombose de bypass PTFE ou VGS, trombose intra-stent, trombose de aneurisma ou entrapment poplíteo e embolia arterial. De acordo com a classificação de Rutherford na IAM foram observados no grau I 12,5%, grau IIa 77,3% e grau IIb 10,2%. As taxas de patência primária foram de 72,8% e 47,8% a um e três anos, respectivamente. A reintervenção foi de 27,6% no grupo da trombose de artéria nativa, 65,2% no grupo da trombose de bypass de PTFE, e 18,2% no grupo da trombose intra-stent. Não foram verificadas reintervenções para os grupos de aneurisma poplíteo ou embolia arterial. A sobrevida livre de amputação foi de 83,3% aos 27 meses, e a incidência cumulativa de morte foi de 10,1% aos 32 meses. Observaram-se complicações em 40 procedimentos (31,3%); a maioria hemorragia minor do local de acesso e uma morte devido a acidente vascular cerebral hemorrágico.  Conclusão:  A TDC embora associada a um risco acrescido de complicações hemorrágicas, é considerada um tratamento seguro e com resultados que podem reduzir a necessidade de tratamento cirúrgico convencional em doentes selecionados. O nosso estudo vem reforçar o uso desta terapêutica como uma opção válida na IAM em diferentes etiologias.]]></p></abstract>
