ABSTRACT
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.

Abstract 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.

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.
