ABSTRACT
Twelve diagnostic and therapeutic angiograms were performed in 10 patients with chronic renal failure using gadodiamide and CO2 as vascular contrast. Renal function was evaluated with serum creatinine levels 24 hours before and 24 to 48 hours after the vascular procedure. Imaging quality and tolerance of these contrast agents were also studied. There was no significant increase in serum creatinine levels in the 12 procedures. In all cases but one, the combined use of gadodiamide and CO2 offered images of enough quality and definition for diagnosis and therapy. A good symptomatic tolerance was present in all procedures. Gadodiamide and CO2 seem to represent useful and safe contrast agents for angiography and endovascular intervention in patients with chronic renal failure. Further experience is needed to confirm these initial findings. (AU)

El test respiratorio utilizando urea marcada con C es un método no invasivo empleado desde 1988 para detectar la presencia de Helicobacter pylori en pacientes portadores de enfermedad ácido péptica. Este método ha demostrado una sensibilidad del 90,2 por ciento y especificidad de 83,8 por ciento . En el Centro de Medicina Nuclear de Guanabara fueron realizados 1.200 test respiratorios, de los cuales el 67 por ciento se reportaron positivos, realizándose nuevos controles después del tratamiento médico, con resultados negativos(AU)

Se presenta una casuítica personal de 286 colecistectomías por video celioscopia realizadas en un período de 22 meses, sin mortalidad, sin conversiones ni reintervenciones. Se hacen algunas consideraciones técnicas, y se propone la colangiografía operatoria sistemática
