[Study of the arterial vascularisation of the esophagus of micro-angiography].

Study of the intrinsic vascularization of the oesophagus in eleven organs. A technic of microangiography was used. The thoracic portion of the oesophagus was carefully studied. The way of penetration of the nutrient arteries and the intraparietal vascular pattern were precised. The vascularization is rather poor, especially 4-5 cms above the oesophagal hiatus.
