Endovascular revascularization of chronic total arterial occlusion of the lower limb using the SAFARI technique.

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.

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.

Nationwide prevalence and clinical characteristics of inpatient diabetic foot complications: A Peruvian multicenter study.

OBJECTIVE: To evaluate the burden of diabetic foot complications amongst inpatients in Peru. MATERIALS AND METHODS: Cross-sectional multicenter study, performed in public hospitals, in one-day enrollment between October and December 2018. RESULTS: We included 8346 patients from 39 national hospitals. Diabetic foot (DF) inpatient point prevalence was 2.8% (CI 95% 2.4-3.1), and DF point prevalence among Diabetes Mellitus (DM) inpatients was 18.9% (CI 95% 16.7-21.1). DF prevalence was higher in jungle and coastal hospitals than highlands ones, and there was no difference according to its care complexity level. Of the 234 patients with DF, 73% were males, age average was 62 ± 12 years, with DM mean time duration of 15 ± 9.9 years. Regarding to DF etiology, 91% and 68% had some degree of peripheral neuropathy and peripheral artery disease, respectively. According to the Infectious Diseases Society of America criteria, 61% presented moderate to severe infections, and 40% had bone involvement. Debridement within 48 h was performed in 36% of sepsis cases. CONCLUSION: Peru has a substantial burden of DF disease, with a greater share of that burden falling on less equipped hospitals in the country's jungle and coastal regions. Interdisciplinary teams and pathways may improve the time of surgical debridement in the highest risk patients.

Reconstrucción temprana en el tórax inestable con sistema de osteosíntesis torácico: Reporte de caso / Early unstable chest reconstruction with thoracic osteosynthesis: A case report

Se presenta el caso de un paciente varón con tórax inestable. Esta lesión es una entidad poco común que puede ser originada por múltiples traumatismos de alto impacto. El diagnóstico se estableció por signos clínicos y estudios de imágenes. El paciente recibió tratamiento quirúrgico con un sistema de osteosíntesis costal (StraCos®); se discuten los resultados obtenidos y sugerencias para casos de este tipo. (AU)

We present the case of a male patient with unstable chest, which is a rare entity that may be caused by high impact trauma. The diagnosis was stablished by clinical manifestations and image results. The patient received surgical treatment with a rib osteosynthesis. We discussed the results obtained and propose suggestions to manage this kind of patients. (AU)
