Real-time ultrasound of normal adrenal glands and small tumors.
1984
The adrenals were studied prospectively with real-time ultrasound in a series of 60 healthy individuals and 13 patients with small adrenal masses sized 8-20 mm in diameter. In only one of the 60 healthy subjects was a normal adrenal gland delineated as a distinct hypoechoic structure. In all other instances only the highly echogenic suprarenal fat could be displayed. Visualization of small tumors was successful in 12 of 13 patients. The suprarenal area and small lesions were best demonstrated by a lateral intercostal approach using longitudinal and transverse scanning planes. The best access was through the 9th/10th intercostal space at the junction with the anterior and middle axillary lin…
Real-time ultrasound-guided infraclavicular axillary vein cannulation: A prospective study in mechanically ventilated critically ill patients.
2016
Purpose: The main purpose of this study was to define the venipuncture and catheterization success rates and early mechanical complication rates of ultrasound-guided infraclavicular axillary vein cannulation. Materials and methods: We performed in-plane, real-time, ultrasound-guided infraclavicular axillary vein catheterizations under emergency and nonemergency conditions in mechanically ventilated, critically ill patients. Results: We performed 202 cannulation attempts. One hundred and twenty-six procedures (62.4%) were performed under emergency conditions. The puncture of the axillary vein was successful in 98.5% of patients, and the entire procedure success rate was 95.1% (95% confidence…

Los ultrasonidos de alta definición en tiempo real (HDLive US) incorporan un software que calcula la propagación de la luz a través de superficies y en relación con la dirección de la misma. Esta fuente de luz puede ser posicionada libremente con el fin de iluminar las áreas de interés deseadas, permitiendo así imágenes de mejor calidad, una mayor sensación de profundidad y una visión más sencilla de superficies fetales. Mostramos casos de embriones y fetos normales, así como algunas malformaciones para señalar las posibilidades de esta nueva tecnología. El auténtico potencial de esta nueva tecnología esta aún por revelar. La HDLive representa, en nuestra opinión, una verdadera innovación y…
