[Resultados a corto y medio plazo de la técnica de Florida]. / Early and medium-term results of the Florida Sleeve technique for aortic root ectasia

Introduction: Aortic root dilatation is a frequent disease affecting mostly young patients that often requires surgical repair. Surgical techniques in young patients include aortic valve-sparing procedures to avoid prosthetic valve implant. Objective: The aim of this paper is to describe the results obtained in three patients with aortic root dilatation using the Florida Sleeve technique. Methods: From November 2015 to January 2017, three patients with severe aortic regurgitation due to aortic anuloectasic were intervened applying the Florida Sleeve technique. Results: Excellent postoperative results were obtained in the three cases including freedom of aortic regurgitation and any cause re-operation during three years of follow-up. Conclusion: The Florida Sleeve technique is a safe, reproducible technique with a learning curve and lower surgical times than traditional techniques. The medium-term clinical outcomes in terms of morbidity and mortality are good.

Introducción: La dilatación de la raíz aórtica es una patología frecuente que afecta a pacientes jóvenes y su tratamiento es quirúrgico. Las técnicas quirúrgicas de elección en pacientes jóvenes son las de preservación de la válvula aórtica para evitar el implante de una prótesis valvular. Objetivo: El presente trabajo tiene como objetivo describir la técnica de Florida Sleeve y los resultados de nuestra experiencia. Método: Entre noviembre de 2015 y enero de 2017 fueron intervenidos en nuestro centro tres casos de pacientes con insuficiencia aórtica severa secundaria a anulectasia aórtica en los que se realizó la técnica de Florida Sleeve. Resultados: En los tres casos se obtuvieron excelentes resultados postoperatorios, libres de insuficiencia aórtica residual y de reoperación por cualquier causa, resultados que se mantuvieron a los tres años de seguimiento. Conclusiones: La técnica de Florida Sleeve es una técnica segura, reproducible con una curva de aprendizaje y tiempos quirúrgicos inferiores a las técnicas tradicionales. Los resultados clínicos a medio plazo en términos de morbimortalidad son buenos.

Fibrosis mediastínica post-irradiación: un factor a tener en cuenta en cirugía cardiaca / Post-radiation mediastinal fibrosis: a factor to take into account in cardiac surgery

Resumen La radioterapia mediastínica es uno de los tratamientos fundamentales de las enfermedades malignas torácicas, pero también representa una causa potencial de complicaciones, tanto a corto como a largo plazo. Se presenta una serie de casos de rotura de vena innominada durante esternotomía media en pacientes con fibrosis mediastínica. Los tres casos descritos corresponden a pacientes intervenidos de cirugía cardiaca con antecedentes de radioterapia mediastínica, entre 15-30 años antes de la cirugía, por tres diferentes enfermedades malignas (linfoma de Hodgkin, timoma y cáncer de mama). En los tres casos se reporta rotura de la vena innominada, con desinserción de su origen en la vena cava superior debido a fibrosis mediastínica intensa.

Abstract Although mediastinal radiotherapy is one of the basic treatments of malignant thoracic diseases, it is also a potential cause of short and long-term complications. A series of cases of rupture of the innominate vein during sternotomy are presented in patients with mediastinal fibrosis. The three cases described correspond to patients intervened by cardiac surgery, with a history of mediastinal radiotherapy between 15 to 30 years before the surgery, due to three different malignant diseases (Hodgkin lymphoma, thymoma, and breast cancer). In the three cases, a rupture of the innominate vein is reported; with de-insertion of its origin in the superior vena cava sue to intense mediastinal fibrosis.

Ligature of the Left Main Coronary Artery after Surgery in Kawasaki Disease: Case Report.

We report a case of a 23-year-old man who was diagnosed with Kawasaki disease that progressed to a coronary aneurysm in the left main coronary artery (LMA). He had suffered from acute coronary syndrome and then underwent an emergent percutaneous coronary angioplasty, in which a polyurethane-covered stent was placed inside the aneurysm. The stent was thrombosed one year later, despite the patient had been treated with anticoagulant and antiplatelet therapy. Emergency percutaneous intervention was then performed. LMA was reopened and stent malposition was observed. Therefore, urgent coronary bypass grafting was performed in which a high degree of competitive flow was observed through the reopened stent. LMA was ligated at the inflow of the aneurysm, resulting in an improvement of graft flow. Left main ligature has not been previously reported.

Rotura iatrogénica de electrodos de marcapasos permanente en la realización de esternotomía media: presentación de un caso / Iatrogenic rupture of permanent pacemaker electrodes while performing a median sternotomy: a case report

RESUMEN La esternotomía media continúa siendo el gold-standart de abordaje quirúrgico en cirugía cardiaca. Aún realizada correctamente, la apertura media del esternón presenta complicaciones en el 1-5% de los casos que varían en su gravedad desde la infección de la herida quirúrgica a la lesión de estructuras intratorácicas. En el presente estudio se describe un caso de rotura de electrodos de marcapasos tras esternotomía media por retracción y fibrosis del tronco venoso braquiocefálico. Debido a la ausencia de artículos semejantes en la literatura y al extendido empleo de la esternotomía en pacientes portadores de marcapasos permanente, se pretende disminuir las lesiones asociadas mediante la publicación de un infrecuente caso de lesión iatrogénica durante la apertura esternal, con escasos precedentes en la literatura publicada hasta la fecha.

ABSTRACT Median sternotomy is still the gold-standard surgical approach in cardiac surgery. Even correctly performed, the sternum median opening presents complications in an incidence of 1-5% of cases comprising in severity from infection of the surgical wound to the injury of intrathoracic structures. We describe a case in which the pacemaker leads were broken after median sternotomy because of the brachiocephalic vein fibrosis. Due to the absence of similar items in the literature and the widespread use of sternotomy in patients with permanent pacemakers, we intended to reduce associated injuries by posting a rare case of iatrogenic injury during sternal opening with few precedents in the literature.
