[Fetal echocardiography during the 2nd half of pregnancy. Biometry and functional approach].

Fetal cardiac biometry was conducted in the TM mode, after real time anatomical outlining of the plane of the four cardiac cavities, on 48 recordings of supposedly normal pregnancies of 23 to 39 weeks of amenorrhoea. Ten measurements were made for each patient, in an immediately subvalvular plane perpendicular to the septum (dimensions of the two ventricular cavities, of the wall of the two ventricles, and of the septum, in diastole and systole respectively). Functional results derived from this data showed that the difference between diastolic and systolic values for ventricular diameters increased with term, the ratio of the diastolic diameter of the right ventricle (RV) to that of the left ventricle (LV) was a constant: 1.23 +/- 0.12, and the size of the RV was always superior to that of the LV (+ + +). Alson noted was that percentage shortening of the LV was superior to that of the RV, and mean percentage thickenings of the RV and septum were inferior to that of the LV. A further observation was that interpretation of the kinetic of the septum requires precise knowledge of the plane of the section in relation to "the pivot point".

[Contribution of echotomography to the study of parotid diseases].

Echotomography of the parotids in 88 patients was successful in detecting normal parotid morphology or inflammation of the parenchyma (parotitis) in 100 p. cent of such cases, and detecting the precise localization of tumors (adenopathies or intraparotid tumors) up to 3 mm in diameter in 93 p. cent of cases. Though cystadenomas do not provide a specific image, their appearance is typical. Positive diagnosis was possible in 85 p. cent of mixed tumors of 1 cm diameter or more, and in 5 out of 7 cases of malignant lesions. The diagnostic value of this examination is markedly limiting that of parotid sialography.

[Congenital esophagotracheal fistulas in adults. Apropos of 2 cases].

Repeated bronchopneumopathies are the principal manifestation of congenital esophagotracheal fistulae detected at a late stage. Diagnosis is suggested by air distention of the esophagus on the thoracic image. Esophageal barium swallow examination in the standing position is usually negative: esophageal transit is too rapid, the diameter of the fistula is too small, and its ascending pathway does not allow filling by the contrast medium. Examinations should be conducted in precubitus, after the passage of an esophageal sound, employing barium sulphate as the contrast medium, and with a horizontal beam and profile projection. Kinetic exploration, employing ampliphotography is necessary. The fistula pathway is seen as a thin opaque line, oblique from above forwards, and pushing from the anterior surface of the esophagus to the posterior surface of the trachea. There is associated filling of the tracheobronchial tract.

The contribution of bidimensional echocardiography in the diagnosis of cardiac tumours. Based on 25 observed cases.

This paper reviews 25 intracardiac tumours (12 myxomas and 13 thrombi) studied by T.M. echography, bidimensional (2-D) echography and cineangiography during a two year period. In addition, five cardiac tumours (two myxomas, three thrombi) were studied by echography alone, and correctly diagnosed. T.M. echography gives false negative results, whereas both 2-D echo and cineangiography give reliable diagnosis. However, 2-D echo should be the procedure of choice as it is non-invasive, and may be used on patients with equivocal symptoms. Since bidimensional echography has become available during the past two years, 12 myxomas have been correctly diagnosed, compared to 14 found during the previous 13 years.

[Assisted circulation during coronarography: advantages and limitations. A report on 63 cases (author's transl)].

During 2588 coronarography examinations conducted over a period of 4 years, assisted circulation was employed in 63 cases to reduce the risks of the examination procedure in particularly debilitated patients. These high risk cases included 48 patients with unstable angina resistant to medical treatment and 45 cases of recent infarcts with complications. Mortality with assisted circulation was very low, in spite of the severe nature of the affections, but the authors use this technique in only a limited number of cases, mainly because of the risk of lower limb ischemia, and the possibility of using intravenous nitroglycerin and analgesia from neuroleptics for examination. For this reason the number of cases examined in this way has dropped from 4% in 1977 to 2% in 1978, though assisted circulation is still employed in certain particularly severe cases of angina, and for infarcts with complications.

[Benign fibrolipomyomatous tumor of the perinephric capsule. A report on one case].

The authors describe a case of perinephric capsule tumor and emphasize the difficult in establishing diagnosis by radiological and especially angiographic investigations. The exact nature of the tumor can be determined only by histological examination. They review the published literature which demonstrates the rare nature of capsular fibrolipomyomata having clinical manifestations, the difficulty in making a differential diagnosis from hamartoma, and the possibility of malignant changes occurring in the tumor.

Renal adenomas.

In presenting five new cases of renal adenomas the authors describe the general nature of these rare tumours. If the small adenoma corresponding to microscopic forms is frequent, the large adenoma is rare and always solitary. Haematuria and pain are the most common signs. The classic criterion of non-malignancy in a solid tumour measuring less than 3 cm has no diagnostic value. From a review of the lieterature on the subject, the authors demonstrate the angio-architecture corresponding to the different types of adenoma: the tubular adenoma which is hypervascularised and well circumscribed; the papillary adenoma, often cortical, hypovascular or avascular with bordering arcade; the alveolar adenoma; the mixed forms. They stress the difficulty of radiological diagnosis and the frequency of transitional forms with cancer. The place of angiography is in the pre-operative diagnostic assessment and in defining localised anomalies in angio-architecture which can guide histological examination in the search for neoplastic foci.

[The accuracy of angiography in the evaluation of benign renal tumours (author's transl)].

The authors review the literature regarding the angiography of three benign renal tumours: adenoma, angiomyolipoma and angioma. Renal adenomas area rare. Oncocytomas can be classified with papillary adenomas; they are fairly characteristic and can be diagnosed pre-operatively. The tubular, and particularly alveolar form cannot be distinguished angiographically from a carcinoma. Angiomyolipomas (hamartomas) occur in tuberous sclerosis or may be found alone. Angiography can first of all be an aid to topographic classification. Its isolated occurrence may cause difficulties in differentiation from a carcinoma. Certain angiographic signs may enable pre-operative diagnosis: the demonstration of aneurysmal arterial changes, linear course of tumour veins and the frequency of a peri-renal haematoma. Angiolipoma is the renal tumour which is most frequently complicated by pre-renal bleeding. Capillary, plexiform or cavernous angiomas are rare. If the first two are large enough (2 cm), their homogenous hypervascularisation may permit preoperative diagnosis. The diagnosis of cavernous angiomas is more difficult.

[Role of scintigraphy in the localization of pheochromocytoma].

Of the metabolic precursors of the catecholamines fixed by the adrenal medulla, 131I marked thyrosine was chosen as a radio-tracer. 6 positive results out of 11 pheochromocytomas confirmed at surgery were obtained in a series of 23 patients. This result is comparable with the results of arteriography but there are more false positives, reflecting the insecurity of this technique which is otherwise quite innocuous.

[Angiomyolipomas (hamartomas) of the kidney. Radiological study apropos of 2 cases. Review of the literature].

Two patients with renal angiomyolipomas studied angiographically are reported:--A case of tuberous sclerosis with bilateral multiple lesions, renal, hepatic and adrenal;--An isolated lesion whose preoperative diagnosis allowed the excision of the tumor. A review of the literature from 1965 to 1977 identified 242 cases of which 177 were isolated angiomyolipomas. There were 54 cases associated with tuberous sclerosis and one with von Hippel-Lindau disease. The radiologic and especially the angiographic signs are illustrated, the hemorrhagic risks are stressed, and the diagnostic features of fetal renal hamartoma are described.

[Voluminous hypernephroma of intermittent development. Diagnostic difficulties (author's transl)].

The authors report a case of cancer of the kidney of intermittent development for which nephro-urotomography was negative. They stress the interest of: --preliminary echotomography in patients with palpable masses in the left hypochondrium; --pharmaco-angiography for improved visualization of masses that are only weakly opaque; --a rapid infusion technique, proposed by various authors, which appears to be the most appropriate for the study of this type of mass which is mainly intermittent in its development.
