[Radiological patterns of truncus arteriosus on X-ray plain film (author's transl)].

Fifteen cases of truncus arteriosus have been studied on frontal and lateral views of thoracic X-ray plain film in infants and children. In infants (12 radiological records), the left middle segment is concave or straight, mainly at the lower part and this pattern is typical if associated with an active pulmonary hypervasculature. Cases without marked pulmonary hypervasculature are very difficult to diagnose. On 7 lateral X-ray films we noted three patterns of empty retrosternal space which were visible at birth. In children from 2 to 6 years, a pattern of cardiomegaly with right aortic arch and pulmonary hypervasculature is very typical. In children older than 6 years, we noted a typical Eisenmenger syndrome. The pattern of empty retrosternal space was marked. In our experience, association of right aortic arch with pulmonary hypervasculature is very typical.

Radiologic patterns of the hypoplastic left heart syndrome.

The hypoplastic left heart syndrome is a malformative complex which unfortunately can not be treated surgically. This cardiopathy is the result of a serious embryogenic error and takes into consideration the different anatomic varieties described here. Borderline cases are also noted especially isthmic coarctation of the aorta or aortic stenosis in the neonatal period. Though several years ago, the diagnosis of the hypoplastic left heart syndrome was made only on pathology, it is now possible to make this diagnosis using clinical, laboratory and radiologic examinations. However, they are cases that remain difficult to label precisely, especially in minor forms and we feel that these deserve hemodynamic investigations.

Cardiac catheterization: dosimetry on patients.

Our study was made on 49 patients and we used capsules of lithium fluoride. The average fluoroscopy time was 32 min. and the average cinema film length was 76.5 metres. The relationship between the entry dose, the fluoroscopy time and the length of cinema film allowed us to calculate a fluoroscopy equivalent time (F.E.T) for each patient which was of 51 min. (32 min. + 76/4) as radiation dose of one minute fluoroscopy equal radiation dose of 4 metres of cinema film. The average heart dose was 0.70 X 10(-3) X FET (GY) or 70 mr/min. There was an absence of relation of the exit dosage to the diameter of the patient and a proportionality of the heart dose to the exit dose. Furthermore the maximum eye dose recorded was 200 mrads and the maximum gonadal dose was 350 mrads.

Congenital arterio-venous fistulas (4 systemic extra-visceral fistulas).

Arterio-venous fistulas are rare in children but usually congenital. We report four cases which are very unusual because of their origin or their localization. We compiled a classification of congenital fistulas which is easily used and collected 582 cases of congenital arterio-venous fistulas from the literature.

[Central nervous system complications in patients with cyanotic congenital heart diseases (author's transl)].

The Author studies neurologic complications and neuro-psychic development in children with cyanotic congenital heart diseases about his experience and the data of the literature. Central nervous system complications in cyanotic children are of two types: cerebrovascular accidents and brain abcess. Cerebrovascular accidents are more frequent before 4 years of age; they are acute and unexpected. Anoxia and hypochromia are the most important factors with acidosis and hemoconcentration. In children after 4 years of age chronic hypoxia and high level of hematocrit are of concern, sometimes with coagulation disturbances. The mortality rate is 10 to 15 per cent. Brain abcess is rare before 3 years of age, the main age is between 8 and 10. The factors are: chronic brains lesions, bacteriemia without pulmonic filter by right to left shunt. The mortality rate is 25 to 33 per cent. The treatment is essentially neuro-surgical, with often severe sequellae. Many factors influence neurologic and intellectual development in cyanotic children, including chronic brain hypoxia, physical limitation, familial habits. For all types of neuropsychic damages early corrective surgery seems to be the best preventing treatment.
