[Pulmonary atresia (with ventricular septal defect)].

The study has been carried out on eight cases of pulmonary atresia with ventricular septal defect, this abnormality involves both valvular atresia and the stenosis of the outflow tract of the right ventricle; that means a pulmonary atresia both valvular and infundibular. The atresia is always combined with a dextroposition of the aorta, overriding the ventricular septum; often with an auricular septal defect or a patency of the foramen ovale. In two cases, other associative caridac malformations exist : either a single ventricle or an atresia of the tricuspid valve. The arterial supply to the lungs may be assured by a persistent duct or by systemic arteries, or an association of both.

[Arteries of the opto-peduncular region of the sheep].

The main features of the arterial plane of the base of the brain of 15 sheep are studied. Details of the topography and the importance of the manifold twigs going to the optic-peduncular formations and grey central nuclei are given also. In spite of the presence of a peculiar arterial polygon, since it has direct supply from a rete mirabile and that it depends almost exclusively on the external carotid arteries, the general diagram of the different arterial pedicles appears comparable with what was formerly pointed out in the dog (LIBERSA an coll., 1974) and even in man. It seems to be a proof of the morphological independance of the cerebral arterial system beyond the arterial polygon. The reason of the existence and appearance of the arterial plane of the base of the brain (internal carotid, external carotid, vertebral arteries) keeps an essentially functional meaning.
