Peri-prosthetic infection in the postoperative period of endovascular abdominal aorta aneurysm repair: treatment by percutaneous drainage / Infecção periprótese no pós-operatório do reparo endovascular de aneurisma de aorta abdominal: tratamento por drenagem percutânea

ABSTRACT Endovascular aneurysm repair is an established technique for treating many infrarenal aortic aneurysms. Infection is one of the most serious complications of this technique, and although percutaneous treatment has been well established for intra-abdominal collections, its use to treat peri-prosthetic fluid collections has not been well determined. In this article we describe a small series of three patients who were treated with percutaneous drainage, with good clinical and imaging responses. Percutaneous drainage is a safe, effective and minimally invasive approach for treating this potentially fatal complication.

RESUMO O reparo endovascular de aneurisma é uma técnica para tratamento de diversos aneurismas infrarrenais da aorta. A infecção é uma das complicações mais sérias desse tratamento, e a abordagem percutânea tem sido adotada para coleções intra-abdominais, mas seu uso para tratamento de coleções protéticas vasculares não está bem estabelecido. Descreve-se, neste trabalho, pequena série de três pacientes tratados com drenagem percutânea, que apresentaram boa resposta clínica e de imagem. A drenagem percutânea mostrou-se abordagem segura, efetiva e minimamente invasiva para tratamento desta complicação, que é potencialmente fatal.

Preparation of constant negative pressure drainage tube and the evaluation of its effect / 中国医师杂志

Objective To explore the drainage effect of drainage tube with different materials on the basis of a constant nega tive pressure drainage,and its impact on flap survival.Methods The most common clinical used Polyvinyl chloride resin (PVC)pipe,latex tubes,silicone tube drainage tubes,and flaps were compared at different phases of the drainage,to determine the best clinical flap with drainage material.After three groups of flaps were designed,including a constant negative pressure drainage device,without a constant negative pressure drainage system,and drainage alone (no negative pressure) drainage flap,the flap survival was observed at different phase space.Three different drainage drainage ways of the flap and the flap survival area of effect were statistically analyzed.Results The silicone tube drainage was more fully and effectively.Constant negative pressure drainage volume of liquid was up to the flap with drainage to the fullest,the highest rate of skin flap healing,and better healing.Conclusions The constant negative pressure in the drainage of the flap makes drainage more fully,and promotes rapid healing of wounds,while the silicone tube is suitable for flap drainage.

Drenagem pleural / Drainage of pleural fluids

A drenagem pleural é procedimento cirúrgico largamente utilizado na prática médica diária, que permite o restabelecimento das pressões negativas no espaço pleural. Apesar de ser considerado ato relativamente simples, poderá levar à graves complicações devido a falta de cuidados que precisam ser respeitados. Procuramos ressaltar alguns aspectos que, se não respeitados no seu conjunto, acabam determinando o insucesso dos procedimentos de drenagem de tórax.

Drainage of pleural fluids, which allows for the reestablishment of negative pressures in the pleural space, is widely employed in routine medical practice. Despite being considered a relatively simple act, it may lead to severe complications if adequate care is not taken. We will highlight some aspects which, if not well tended to, will result in unsuccessful outcome of chest drainage procedures.
