[Percutaneous punctures guided by echography].

It is possible to carry out percutaneous injections of lesions in any organ under the direction of echography. This is particularly so in the liver, pancreas and kidney. The procedure has been used in 79 patients for diagnostic and/or therapeutic purposes and has provided very good and promising results. The technique is harmless, causes only minimum discomfort to the patient and, in many cases, enables the routine diagnostic approach to be short-circuited because more laborious, expensive techniques can be avoided.
