title: [Aortocoronary bypass permeability explored by tomodensitometry. Preliminary study].
abstract: The patency of 24 aorto-coronary grafts was studied by tomodensitometry. --16 out of the 18 bypasses examined within the two weeks following surgery were seen. --4 older bypasses were not visible, either by scanner or by angiography and were therefore occluded: two more, performed more than a year previously, were patent on tomodensitometric examination. The interpretation of the results, discussed taking into account the small number of angiographic check ups does not permit any formal conclusion as to the validity of the procedure. The results of this technique seem satisfactory and quite comparable with other non invasive methods used in the study of aorto-coronary grafts.
