RESUMO
Wolff Parkinson White Syndrome occurs due to the presence of accessory pathways that abnormally communicate the atria with the ventricles. It is one of the main causes of paroxysmal supraventricular tachycardia in young people and adolescents, in whom the ideal management is catheter ablation. This syndrome can also occur in younger patients such as neonates and infants, where the therapeutic options are different. We present the case of a 47-day-old patient who was admitted to a public pediatric hospital in Peru due to vomiting. Upon admission, she showed a heart rate of 250 beats per minute; wide QRS complex tachycardia was documented; later, on the electrocardiogram in sinus rhythm, signs of pre-excitation were evident.
RESUMO
RESUMEN Introducción : El leiomiosarcoma uterino es un sarcoma poco frecuente sumamente agresivo, que puede presentar metástasis más frecuentemente a pulmón e hígado. Su pronóstico es malo, siendo la histerectomía total temprana el tratamiento de primera línea Otras alternativas son la quimioterapia con regímenes de doxorrubicina, ifosfamida o gemcitabina, solos o en combinación. Reporte de caso : Presentamos a una mujer peruana de 40 años que fue sometida a histerectomía por sospecha de leiomioma; sin embargo, la patología reveló un diagnóstico final de leiomiosarcoma uterino. No se le pudo notificar debido a la pérdida de seguimiento. Dos años más tarde, volvió a presentar metástasis en muslo, mama, hígado, pulmones y cuero cabelludo. Se le administró Ifosfamida y Doxorubicina cada 21 días durante 3 cursos; sin embargo, debido a la progresión de la enfermedad, se decidió un tratamiento paliativo. Finalmente, falleció dos meses después del tratamiento. Conclusión : Se presenta un caso de leiomiosarcoma uterino con metástasis atípica para promover el diagnóstico precoz y diferenciado de leiomioma, leiomiosarcoma de bajo grado y leiomiosarcoma de alto grado para definir el tratamiento correcto.
ABSTRACT Introduction : Uterine leiomyosarcoma is a rare and highly aggressive sarcoma, which can metastasize most frequently to the lung and liver. Its prognosis is poor, with early total abdominal hysterectomy being the first line treatment. Other alternatives are chemotherapy with regimens of doxorubicin, ifosfamide or gemcitabine, alone or in combination. Case report : We present a 40-year-old Peruvian woman who underwent hysterectomy for suspected leiomyoma; however, pathology revealed a final diagnosis of uterine leiomyosarcoma. She could not be notified due to loss to follow-up. Two years later, she again presented with metastases in the thigh, breast, liver, lungs and scalp. He was given Ifosfamide and Doxorubicin every 21 days for 3 courses, however, due to disease progression, palliative treatment was decided. Finally, he died two months after treatment. Conclusion : A case of uterine leiomyosarcoma with atypical metastasis is presented to promote early and differentiated diagnosis of leiomyoma, low grade leiomyosarcoma and high grade leiomyosarcoma to define the correct treatment.
RESUMO
Resumen Introducción: En los últimos años se han desarrollado diversos dispositivos oclusores que permiten evitar la cirugía cardíaca en los pacientes con cardiopatías congénitas con hiperflujo pulmonar. Objetivo: Describir la experiencia en el cierre percutáneo de las cardiopatías con hiperflujo. Método: Mediante un estudio descriptivo y retrospectivo se revisaron las historias clínicas de los pacientes sometidos a intervencionismo cardíaco de 2016 a 2020. Resultados: De 706 procedimientos realizados en el periodo, el 35% fueron terapéuticos. De ellos, 189 correspondieron a nuestra serie de pacientes intervenidos con diagnósticos de persistencia del conducto arterioso (PCA) (n = 164), comunicación interauricular (CIA) (n = 21) y comunicación interventricular (CIV) (n = 4). Los datos clínicos y demográficos fueron en PCA 3.4 años (0.7-15) y 10.2 kg (6.1-46), en CIA 7.2 años (6-15) y 17.5 kg (15-38), y en CIV 7.25 años (6-9) y 20.75 kg (16-27). Referente al tamaño de los defectos cardíacos, el promedio fue para PCA 4.3 mm, para CIA 19.1 mm y para CIV 6.75 mm. Los dispositivos más utilizados fueron Amplatzer PDA y ASD, y Occlutech PDA. La tasa de éxito fue adecuada: PCA 95%, CIA 90% y CIV 75%. Reportamos una baja incidencia de complicaciones y generalmente menores, como shunt residual y hemólisis. Conclusiones: El manejo intervencionista de las cardiopatías congénitas con hiperflujo pulmonar es cada vez más frecuente con la disponibilidad de oclusores en nuestro medio, así como por el desarrollo de nuevos centros y el mayor entrenamiento de cardiólogos intervencionistas, lo que ha permitido mejores tasas de éxito y menor índice de complicaciones.
Abstract Introduction: In recent years, various occlusive devices have been developed that make it possible to avoid cardiac surgery in patients with congenital heart disease with pulmonary hyperflow. Objective: To describe the experience in percutaneous closure in heart disease with hyperflow. Material and methods: Through a descriptive, retrospective study, the medical records of patients undergoing cardiac intervention were reviewed, from 2016 to 2020. Results: Of 706 procedures performed in this time, 35% corresponded to various therapeutic cases. Of these, 189 corresponded to our series of operated patients with diagnoses of PDA (n = 164), ASD (n = 21) and VSD (n = 4). The clinical and demographic data were: in PDA 3.4 years (0.7-15) and 10.2 kg (6.1-46), in ASD 7.2 years (6-15) and 17.5 kg (15-38), and in VSD 7.25 years (6-9) and 20.75 kg (16-27). Regarding the size of the heart defects, the average was 4.3 mm PDA, 19.1 mm ASD and 6.75 mm VSD. The most used occluding devices were Amplatzer PDA and ASD, and Occlutech PDA. The success rate was adequate, PDA 95%, ASD 90% and VSD 75%. We report a low incidence of complications and generally minor ones such as residual shunt and hemolysis. Conclusions: The interventional management of the congenital heart diseases with pulmonary hyperflow is increasingly frequent with the availability of occlusive as well as the development of new centers and more training of interventional cardiologists, which has allowed better success rates and lower complication rate.
RESUMO
O implante de stents para manter o ducto arterial patente na cardiopatia congênita cianótica éuma alternativa à cirurgia de Blalock-Taussig modificada (BTm) em pacientes de alto risco. Descrevemos osresultados imediatos e de médio prazo do implante de stent em neonatos e lactentes com circulação pulmonarducto-dependente. Métodos: Trata-se de estudo descritivo e prospectivo, que incluiu diferentes cardiopatias congênitas cianóticas tratadas entre 2014 e 2015.Resultados: Avaliamos 14 pacientes, com média de idade de 46 dias e pesando 4,5 kg, sendo a atresia pulmonar associada à comunicação interventricular a cardiopatia mais tratada. A abordagem pela artéria femoral ocorreu em 70% dos procedimentos e, nos demais, por via carotídea. Stents de 3,5 × 12 mm foram usados na maioria dos casos, e o sucesso do implante foi obtido em 78% das intervenções (11/14). Os casos de insucesso foram encaminhados para cirurgia − uma delas em situação de urgência, que resultou em óbito. Ocorreu espasmo ductal < 48 horas em três pacientes que necessitaram de BTm, com evolução favorável. Complicações após a alta e nos primeiros 30 dias incluíram trombose de stent (2/11), uma delas controlada com redilatação e outra que evoluiu para óbito, e uma morte súbita (1/11). A mortalidade total foi de 21,4% (3/14). A patência do ducto arterial nos primeiros 6 meses foi obtida em 5 casos que foram submetidos à cirurgia paliativa.Conclusões: A experiência inicial de implante de stent ductal mostrou resultados imediatos favoráveis, e, emmédio prazo, mais de um terço dos pacientes com circulação pulmonar ducto-dependente manteve seus canaispatentes...
The implantation of stents to keep the ductus arteriosus patent in cyanotic congenital heart disease is an alternative to the modified Blalock-Taussig surgery (mBT) in high-risk patients. This study describes theimmediate and medium-term outcomes of stent implantation in neonates and infants with duct-dependentpulmonary circulation. Methods: This was a descriptive and prospective study including different cyanotic congenital heart diseases treated between 2014 and 2015. Results: Fourteen patients with a mean age of 46 days, and mean weight of 4.5 kg were assessed, andpulmonary artresia with interventricular communication was the most treated condition. The femoral artery approach was used in 70% of procedures; carotid approach was used in the remaining cases. Stents of 3.5 x 12 mm were used in most cases, and implant success was achieved in 78% of interventions (11/14). The failed cases were referred to surgery one of them was an emergency, which resulted in death. Ductal spasm occurred in < 48 hours in three patients who required mBT, with favorable outcome. Complicationsafter discharge and within the first 30 days included stent thrombosis (2/11), one of which was controlled with redilation, another progressed to death, and one sudden death (1/11). The overall mortality was 21.4% (3/14). A patent ductus arteriosus in the first 6 months was present in five cases, which underwent palliative surgery.Conclusions: The initial experience of ductal stenting showed favorable immediate outcomes, but in the mediumterm, little more than a third of the cases maintained a patent ductus arteriosus within 6 months...
