Bone regeneration and tissue acceptance of human fascia lata grafts adjacent to dental implants: a preliminary case report.

The biologic principle of guided tissue regeneration (GTR) has been studied extensively in hopes of regenerating alveolar bone. Various materials have been utilized as regenerative membranes; however, all materials have disadvantages, and the ideal membrane material is yet to be identified. In this case report, human freeze-dried fascia lata strips were used as a regenerative barrier membrane in conjunction with the placement of endosseous root implants and demineralized, freeze-dried bone allograft. The major advantage in the use of human fascia lata for guided tissue regeneration is that a second procedure to remove the material is not necessary, and the fascia is accepted by the surrounding tissues without complication. There is acceptance of four endosseous root-form dental implants that were immediately placed into fresh extraction sockets and covered with demineralized freeze-dried bone allograft (DFDBA), with human freeze-dried fascia lata used to serve as a biocompatible, collagenous, regenerative augmentation membrane over the dental implants. The biologic concept of GTR is clinically applied to increase the dimensions of the edentulous, maxillary alveolar ridge with use of human freeze-dried fascia lata barrier membranes.

Use of an autogenous hypogastric artery patch graft for living related donor kidneys with multiple renal arteries.

A kidney with triple renal arteries was removed from an HLA identical donor and transplanted to her brother using the donor hypogastric artery as an autogenous graft. The kidney was preserved by hypothermic, hyperkalemic, hyperosmolar washout solution while the three separate renal artery-hypogastric artery autograft anastomoses were being performed in an ex vivo position. Subsequently, the end to side autogenous hypogastric artery patch graft to external iliac artery anastomosis was completed. Prompt renal function occurred and after 18 months the serum creatinine level remained unchanged.
