[Early changes in the structure of vein grafts and their significance in the development of complications after revascularization surgery].
By means of light and electron microscopy the development of regressive changes in the media of vascular graft were studied. The authors found out that as a result of warm and cold ischaemia to which the vascular graft is exposed before implantation changes in nuclei of smooth muscle cells arise. The development of these changes can be postponed by keeping the graft in a suitable medium before implantation. Such medium may be e.g. the patient's blood cooled to 4 degrees C. On a group of their own patients the authors pointed out the significance of these changes in the development of early complications after vascular graft implantation.
