[Real-time sonography of upper abdominal arteries and veins (author's transl)].
Improved resolution of new real time sonographic equipment permits demonstration and demarcation of vascular structures which could not be differentiated formerly. Successful differentiation frequency of upper abdominal vessels and establishment of optimal transducer position were investigated prospectively in 100 patients undergoing sonographic upper abdominal assessment. ⋯ Real-time sonography enables rapid assessment of vascular structures. Pulse and respiration dependent variations of calibre are a valuable means for differentiation.
