RESUMO
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.

BACKGROUND: The optimal management of patients with multivessel coronary artery disease (MVD) admitted with STEMI is under debate. CABG is rarely performed, even on ideal candidates. A provisional PCI without stent implantation may allow complete surgical revascularization (CSR) in a subset of patient that we sought to identify in this study. METHODS: Patients with STEMI from April 2014 to October 2016 were evaluated and those with a TIMI flow <3 in the culprit vessel, and an additional stenosis of >70% in an epicardial vessel or sidebranch >2.5â¯mm were selected. Epidemiological variables, surgical risk scores and SYNTAX and SYNTAX II scores were analyzed. All the selected patients were discussed in a post hoc heart-team, and predictors of 12-month events were also analyzed. RESULTS: Seventy-two (19.0%) accomplished MVD criteria. Mean SYNTAX was 19⯱â¯13 points and SYNTAX II score recommended CABG in 12 patients (16.7%) and heart-team discussion in 60 (83.3%). All patients were discussed in a post hoc heart-team, which concluded that 21 (29.2%) patients could have been good candidates for CSR. After one year follow-up, SYNTAX II PCIâ¯>â¯40 was found to be the sole independent predictor for 12-month events (OR 12.9 [2.7-62.1], pâ¯=â¯0.001). CONCLUSIONS: MVD and STEMI with a SYNTAX II PCIâ¯>â¯40 should be discussed in an ad-hoc heart team, after a provisional revascularization of the culprit vessel, and should be considered for CSR, especially when the RCA is the culprit artery and there is a complex disease in the left coronary artery.
