  • Title: The vascular pattern and viability of microvascularized rib grafts based on periosteal circulation--an experimental study.
    Author: Papanastasiou VW, Lalonde DH, Williams HB.
    Journal: Ann Plast Surg; 1984 Nov; 13(5):375-82. PubMed ID: 6240217.
    Abstract:
    Previous reports have stressed the importance of the nutrient blood supply in rib grafts transferred by microvascular anastomoses. In the present experimental study, we have demonstrated that a rib graft transferred by microvascular anastomoses based on periosteal vessels can survive; vascular clearing studies demonstrated that the vascularity of these grafts extends not only into the cortex but the medulla as well. The relative facility of harvesting these grafts (compared with those based on nutrient vessels) should make them the favored choice. Technetium bone scintigraphy proved accurate in the assessment of both vascular pattern and microanastomotic patency. Tetracycline labeling did not correlate well with the patency of a rib graft's pedicle blood supply.
