ABSTRACT

Abstract The SAFARI technique or Subintimal Arterial Flossing with Antegrade-Retrograde Intervention is an endovascular procedure that allows recanalization of Chronic Total Occlusive (CTO) lesions when conventional subintimal angioplasty is unsuccessful. Retrograde access is usually obtained through the popliteal, anterior tibial, dorsalis pedis artery, or posterior tibial arteries and may potentially provide more options for endovascular interventions in limb salvage. The case of an 81-year-old man with a history of uncontrolled hypertension, diabetes mellitus, and dyslipidemia is presented. He presented with a cutaneous ulcer on the right lower limb with torpid evolution and poor healing. The Doppler ultrasound and arteriographic study revealed a CTO lesion of the popliteal artery that was not a candidate for antegrade endovascular revascularization, but was successfully treated using the SAFARI technique. The patient had no perioperative complications, the wound showed better healing, and he was discharged with an indication of daily dressings and control by an external outpatient clinic.


Resumo A técnica SAFARI, ou Subintimal Arterial Flossing with Antegrade-Retrograde Intervention, é um procedimento endovascular que permite a recanalização de lesões por oclusão total crônica (OTC) em caso de fracasso da angioplastia subintimal convencional. O acesso retrógrado é geralmente obtido através da artéria poplítea, tibial anterior, pediosa ou tibial posterior e pode fornecer mais alternativas de intervenções endovasculares para o salvamento do membro. É apresentado o caso de um homem de 81 anos com histórico de hipertenção não controlada, diabetes melito e dislipidemia. Ele apresentava uma lesão ulcerativa cutânea no membro inferior direito com evolução tórpida e má cicatrização. O ultrassom Doppler e o estudo arteriográfico revelaram uma lesão por OTC na artéria poplítea. O paciente não era candidato a revascularização endovascular anterógrada; sendo assim, esta foi realizada com successo utilizando a técnica SAFARI. O paciente não apresentou complicações perioperatórias e recebeu alta com indicação de cuidados diários com a ferida e controle em um ambulatório externo. Além disso, a ferida apresentou melhor cicatrização.

ABSTRACT

Objetivo: Describir las características clínicas y epidemiológicas de la candidemia en un hospital de tercer nivel del sur del Perú durante los años 2011-2014. Materiales y métodos: Estudio retrospectivo realizado en el Hospital Nacional Carlos Alberto Seguín Escobedo (HNCASE) de la ciudad de Arequipa, Perú. Revisamos las historias clínicas de los pacientes que tuvieran al menos un hemocultivo positivo para Cándida sp. Las características evaluadas fueron la edad, sexo, servicio de procedencia, alteración del sistema inmune, colonización previa por hongos, neoplasia, insuficiencia renal crónica, diabetes, uso de corticoides, uso de dispositivo invasivo, exposición a antibióticos de amplio espectro, ventilación mecánica, hemodiálisis, nutrición parenteral total, sepsis grave, cirugía previa, y días de estancia hospitalaria. Resultados: Entre el 2011 y 2014, 71 pacientes presentaron candidemia. Los servicios con mayor cantidad de pacientes infectados fueron la unidad de cuidados intensivos (UCI) 17 (23,94%) y medicina interna 17 (23,94%). Las especies aisladas fueron C. albicans 33 (46,48%), C. paralopsilosis 16 (22,54%), C. glabrata 9 (12,68%), C. tropicalis 8 (11,27%), C. guillermondi 4 (5,63%), y C. krusei 1 (1,41%). Las características más frecuentes de estos pacientes fueron el uso de dispositivo invasivo (88,73%) y la exposición a antibióticos de amplio espectro (83,1%). Conclusión: La candidiasis es una enfermedad poco frecuente en el HNCASE, producida principalmente por C. albicans, C. paralopsilosis, y C. glabrata. Las características más frecuentes de estos pacientes fueron el uso de dispositivos invasivos y la exposición a antibióticos de amplio espectro


Objective: To describe the clinical and epidemiological characteristics of candidemia in a tertiary hospital in southern Peru during the years 2011-2014. Materials and methods: Retrospective study conducted at the Carlos Alberto Seguin Escobedo National Hospital (HNCASE) in the city of Arequipa, Peru. We reviewed the medical records of patients who had at least one positive blood culture for Candida sp. The characteristics evaluated were age, sex, service of origin, alteration of the immune system, previous colonization by fungi, neoplasia, chronic renal failure, diabetes, use of corticosteroids, use of invasive device, exposure to broad spectrum antibiotics, mechanical ventilation, hemodialysis, total parenteral nutrition, severe sepsis, previous surgery, and days of hospital stay. Results: Between 2011 and 2014, 71 patients presented candidemia. The services with the highest number of infected patients were Intensive Care Unit (ICU) 17 (23.94%) and Internal Medicine 17 (23.94%). The isolated species were C. albicans 33 (46.48%), C. paralopsilosis 16 (22.54%), C. glabrata 9 (12.68%), C. tropicalis 8 (11.27%), C. guillermondi 4 (5.63%), and C. krusei 1 (1.41). The most frequent characteristics of these patients were the use of invasive device (88.73%), exposure to broad spectrum antibiotics (83.1%). Conclusion: Candidiasis is a rare disease in HNCASE produced mainly by C. albicans, C. paralopsilosis, and C. glabrata. The most frequent characteristics of these patients were the use of invasive devices and exposure to broad spectrum antibiotics
