[Neonatal aortic valvular stenosis. Apropos of 8 cases].

Congenital aortic stenosis presenting in the neonate must be distinguished from the commoner hypoplastic left heart-syndrome, which is beyond surgical correction. It is certainly a serious problem, but early diagnosis and supporting angiography to rule out the presence of an associated left ventricular malformation and to check the volume of the left ventricular cavity should lead to a decision to operate. Out a 4 neonates from this series who were presented for surgery, the 2 survivors had good long-term results.

[A case of parieto-pulmonary acquired shunt presenting with hemoptysis (author's transl)].

The authors report the case of a 52 year old man with arteriovenous shunt developing from the 7th left intercostal artery, revealed by hemoptysis and proved by intercostal selective arteriography. The patient had a past history of serofibrinous pleurity 29 years previously and had undergone paracentesis at this level. The origin of this shunt is then discussed.

[Ebstein's malformation in newborn infants. Apropos of 8 cases].

In relation with 8 cases, the features of Ebstein's malformation were studied in the neonatal form. In spite of its rarity, it should be recognized because of its peculiar prognosis, as it is liable to be permanently improved by medical treatment, after a difficult adaptation period. Besides, it is essential to distinguish it from other neonatal heart diseases which ressemble to it, but require an urgent surgical treatment.

[The Kasabach-Merritt syndrome with pancreatic localization in a newborn infant].

The case of a neonate with a large pancreatic hemangioma belonging to the Kasabach-Merritt syndrome is reported. Selective embolization of one of the main vessels originating from the gastroduodenal artery resulted in a progressive increase of blood platelet levels and in a concomitant change in the hemangiomatous structure at ultrasound examination, as well as in a subsequent acceleration of somatic growth. At 8 months of age, there were no more clinical, radiological, ultrasonographic or biological signs of the hemangioma. This case report emphasizes the interest of embolization in the Kasabach-Merritt syndrome.

[Echographic aspects of cerebral sulci in the ante- and perinatal period].

70 fetuses (10 to 37 weeks) and 30 full term infants were examined by ultrasound (U.S.). Anatomic correlations were made with frontal, axial and sagittal sections of 43 fetal and 3 neonatal brains. At 12 weeks gestational age (w.g.a.) only the inter hemispheric fissure is seen by U.S. The sylvian fissure (21 w.g.a.), the callosal sulcus (21 w.g.a.), the parieto-occipital sulcus (25 w.g.a.), the calcarine fissure (25 w.g.a.), the cingulate sulcus (26 w.g.a.) and the collateral sulcus (25-27 w.g.a.) are visualized rather late with in-utero U.S. The other sulci are more difficult to see. The peripheral location of these sulci contributes to the difficulty encountered in their visualization. The morphology of the sylvian fissure is quite characteristic on U.S. imaging and can be used to estimate the gestational age of the fetus. Compared to the embryological development there is a 2-4 weeks delay between the first infolding of the brain and the visualization of a sulcus by U.S. Abnormal sulcal patterns can be recognized based on the normal appearance for each gestational age. Sulcal anomalies are quite specific in holoprosencephaly, lissencephaly, micropolygyry, schizencephaly, agenesis of the corpus callosum. Silhouetting of the sulci may occur if the parenchymal echogenicity is sufficiently increased that the sulci no longer stand out (ischemia, tumors, encephalitis). Thickening of the sulci occurs in subdural hematomas, external hydrocephalus, meningitis and toxoplasmosis.
