Circulation, bone scans, and tetracycline labeling in microvascularized and vascular bundle implanted rib grafts
Journal Article

· Ann. Plast. Surg.; (United States)
The circulation in microvascularized rib grafts has been compared with that in conventional rib grafts and in those augmented by a direct vascular bundle implantation into the bone grafts. A new experimental model has been designed to correlate vascular perfusion, bone scan patterns, tetracycline labeling, and histological findings in these bone grafts. Posterior microvascularized rib grafts were found to have a circulatory pattern identical to that of the normal rib. Failed microvascularized rib grafts were revascularized more slowly than conventional rib grafts. Vascular bundles implanted into rib grafts remained patent and increased the rate of revascularization. The stripping or preservation of periosteum had no observable effects on the rate or pattern of conventional rib graft revascularization. The circulation in rib grafts was accurately reflected in technetium 99 bone scans, as was the patency of the anastomoses of microvascularized rib grafts and of implanted vascular bundles. In contrast, tetracycline labeling was repeatedly observed in avascular areas of bone grafts and, therefore, is not a reliable indicator of bone graft circulation.
