ABSTRACT
El síndrome de vena cava superior (SVCS) resulta de la obstrucción de la vena cava superior, que origina una disminución del retorno venoso procedente de cabeza, cuello y extremidades superiores. Aunque la causa más frecuente siguen siendo procesos tumorales malignos, en los últimos años hemos visto un aumento de causas no tumorales, como trombosis de dispositivos intravasculares permanentes o causas iatrogénicas durante la cirugía cardiaca. Presentamos un caso de SVCS tras cirugía cardiaca tratado de forma satisfactoria mediante técnica endovascular y anticoagulación sistémica
Superior vena cava syndrome (SVCS) results from superior vena cava obstruction, causing a decrease in venous return from the head, neck, and upper extremities. Although the most frequent cause is still malignant tumour processes, in recent years an increase has been observed in non-tumour causes, such as thrombosis of intravascular devices or iatrogenic causes during cardiac surgery. A case is presented of SVCS after cardiac surgery treated satisfactorily by an endovascular technique and systemic anticoagulation

The geochemical behavior of zinc, lead and copper from sulfidic tailings in a mine site with potential to generate acidic drainage (pyrite (55%) and sphalerite (2%)) is reported in this paper. The mining area is divided in two zones, considering the topographic location of sampling points with respect to the tailings pile: (a) outer zone, out of the probable influence of acid mine drainage (AMD) pollution, and (b) inner zone, probably influenced by AMD pollution. Maximum total ions concentrations (mg/L) measured in superficial waters found were, in the outer zone: As (0.2), Cd (0.9), Fe (19), Mn (39), Pb (5.02), SO4(2-) (4650), Zn (107.67), and in the inner zone are As (0.1), Cd (0.2), Fe (88), Mn (13), Pb (6), SO4(2-) (4,880), Zn (46). The presence of these ions that exceeding the permissible maximum limits for human consume, could be associated to tailings mineralogy and acid leachates generated in tailings pile.
