A suprasternal approach to the mediastinum using real-time ultrasonography. Echoanatomical correlations.

This work was undertaken in order to define the potential capabilities of real-time echography for the exploration of the mediastinum by a suprasternal approach. We present the results of a comparative study between anatomical frontal oblique sections of the mediastinum and echographic slices performed along the same planes from the suprasternal fossa. From these data, it seems possible to enlarge the applications of echography in the study of mediastinal pathology.

[Echographic study of the normal adrenal gland during development and in the adult].

An echographic study of the normal adrenal glands is realized on normal out patients, and anatomic slices. A comparison is made between echographic and anatomic images. This study demonstrates the image of the normal adrenal gland in the fetus, newborn and adult, and reveals a different echo pattern in the cortex (sonolucent) and the medulla (echogenic).

[Suprapubic prostatic ultrasonography (author's transl)].

Suprapubic ultrasonography is now routinely used for prostatic examination as it is simple, non-invasive and accurate. Differential diagnosis between benign hypertrophy and cancer is often possible. Evaluation of the size of the prostate is accurate and is a satisfactory means of monitoring the effect of treatment for prostatic cancer.

[Ultrasonographic guidance of percutaneous biopsies and punctures].

Real time ultrasonography is routinely used for guidance of percutaneous punctures towards small targets, with three goals: 1. Aspiration biopsies for analysis of an abnormality detected with ultrasonography. 2. Injection of contrast media inside normal structures (urinary, biliary or pancreatic tract) or abnormal collection (cysts, pseudocysts). 3. Treatment by percutaneous sclerosis, aspiration, decompression, drainage.

[Suprarenal cysts. Diagnostic value of percutaneous puncture guided by echoscopy (author's transl)].

Percutaneous needle aspiration was carried out in one case of suprarenal cysts which had already been evaluated by pyelography, echography and angiography. The characteristics of the aspirated liquid pointed towards a benign lesion, and enabled conservative treatment to be initiated. More generally, diagnosis of suprarenal tumors benefits from the direct approach already applied to other abdominal tumors.

[Percutaneous puncture under sectorial real time ultrasonography control].

A technique for percutaneous puncture is described which employs sectorial scanning real time ultrasonography without a mechanical system for needle control. The method has given satisfactory results in 200 punctures, including one case in which a liver metastasis 13 mm in diameter was detected and another case with a wirsung's duct of 4 mm diameter.

[Gastroduodenal complications after the ingestion of hydrochloric acid. One case (author's transl)].

The ingestion of a caustic acid resulted in retractile fibrosis of 2/3 of the stomach with a secondary duodenal fistula. The antro-pyloro-duodenal circuit was re-established at around the 3rd after ingestion. However, the duodenal fistula caused the formation of encysted pelvic abscesses which were difficult to drain and satisfactorily treat. The clinical course stretched over a period of 4 years.

[A critical study of arteriography of tumours of soft tissue of the extremities (author's transl)].

We feel that arteriography occupies at the present time an indispensable and irreplaceable role in the pre-therapeutic assessment of a soft tissue tumour of the extremities. It obviously cannot provide a definite diagnosis in all cases with regard to the benign or malignant nature of the lesion. However careful analysis of the various features of the images obtained, leading to a radiological classification of the tumour into one of three groups (LEVIN, WATSON and BALTAXE), makes possible, in groups I and III, to predict the nature with a high probability of accuracy. Only in type II (35% of our cases) is it impossible to make such a deduction. The value of arteriography is not limited to diagnosis. It also provides information on the extent and arterial supply of the tumour which are essential to the surgeon and which cannot be supplied by any other investigation.
