RESUMENEl angiomiolipoma renal es un tumor benigno mesenquimático. Constituyen sólo del 2 al 6% de los tumores renales. Existen alrededor de 12 casos reportados con invasión a las venas renales y la cava inferior. En menos de 5, hay extensión de trombo tumoral hasta aurícula derecha. Objetivo: Presentar el caso clínico, manejo y evolución de una paciente con un angiomiolipoma renal con extensión tumoral a vena renal y cava inferior y que compromete la cavidad auricular derecha casi en su totalidad. Paciente y método: 50 años, sexo femenino con hallazgo del tumor por un ultrasonografía abdominal motivada por el estudio de síntomas digestivos de origen probablemente funcional. Se confirma el diagnóstico con TAC y ecocardiograma doppler. Se realiza una cirugía combinada, abdominal y esternotómica, con la ayuda de un by pass aortopulmonar. Resultados: Nefrectomía izquierda, liberación intravascular del tumor que se empuja por cava inferior y se extrae en block por la aurícula derecha. Evoluciona inicialmente en forma satisfactoria, pero desarrolla distress respiratorio con angio TAC de tórax negativo para TEP a las 48 h de la cirugía. Se inicia anticoagulación empírica con HBPM y encontrándose extubada y en buenas condiciones hace un hemoperitoneo el día 14, encontrándose hemorragia en napa en los sitios de disección previa. De alta a los 21 días. El seguimiento alejado a los 2 años revela una hernia incisional, reparada sin incidentes, y sin otras complicaciones ni signos de recidiva de patología original. Conclusión: El manejo de equipo multidisciplinario nos permitió ayudar exitosamente a esta paciente con patología rara y compleja.PALABRAS CLAVE: Angiomiolipoma renal, aurícula derecha. SUMMARYRenal angiomyolipoma is an uncommon benign tumor of mesenchymal origin. In less than five of 12 cases reported with renal vein and inferior vena cava involvement the thrombus extends to the right atrium.

Spontaneous closure of a residual fistula after surgical closure of a traumatic aorto-right ventricular fistula. Report of one case We report a 16-year-old boy, who suffered a right ventricle penetrating injury caused by a sharp blade, that evolved to cardiac tamponade. He underwent surgery and was discharged four days later. Thirteen days later, a cardiac murmur was found. An echocardiography showed an aorto-right ventricular fistula. Surgical closure was performed through an aortotomy on cardiopulmonary by pass. The control echocardiography showed a small residual fistula, which closed spontaneously three months later.

Lung cancer at a Chilean public hospitalBackground: Lung cancer is the world's leading cause of cancer death. Aim: To describe the clinical, staging and survival characteristics of lung cancer in a public Chilean regional hospital. Material and Methods: Analysis of a prospective database of a thoracic surgery service, retrieving histologically confirmed lung cancer cases from January 2010 to December 2019 and reviewing their medical records. Cases were re-staged by the TNM-8 system and variables were compared between periods 2010-2014 and 2015-2019. Results: We retrieved 551 lung cancer cases, 333 (60 %) men, with a mean age of 65 years. Distant metastases were found in 72% of cases (excluding lymphatic metastases). Of the non-small cell lung cancers (NSCLC), 50 (10%) cases were in stage I, 18 (4%) in stage II, 81 (16%) in stage III and 347 (70%) in stage IV. Global five-year survival was 18%, 20% for NSCLC, 71% for excised NSCLC, 8% for non-excised NSCLC, 88% for stage I and 92% for subgroup IA. Resective surgery was performed in 81 (14%) cases. When comparing 2010When comparing -2014When comparing and 2015When comparing -2019 periods, the frequency of resective surgery increased from 7% to 20%. Conclusions: The diagnosis of lung cancer was frequently made in advanced stages. There was a significant increase in early diagnosis and frequency of surgeries with curative intent in the second observation period.
