| Outline of Final Research Achievements |
The long-term patency of small calibre “microbiotubes” with an inner diameter of 0.6 mm is described. No small calibre grafts of acceptable quality are currently available, and it has been difficult to maintain the patency of artificial vessels with an inner diameter of < 3 mm. In this study, 75% of microbiotubes used as allogenic grafts in rats remained patent at 12 months. It is believed that this study makes a significant contribution to the literature as it demonstrates that microbiotubes have high compatibility, stability, and durability as long-term replacement grafts and may be usefully applied to microsurgery.
