While bone is inherently capable of regeneration, complications such as excessive bone loss impede healing, necessitating the use of bone grafts. In the United States alone, an estimated 15 million fractures occurs annually, including 1.6 million hospital admissions for traumatic fractures and 2 million osteoporotic fractures, costing over 60 billion dollars and calling for 1.6 million bone gra...

INTRODUCTION Augmentation rhinoplasty could be defined as the method whose goal is to increase the dimensions of the nasal pyramid, both the dorsum and the tip. For a long time, surgeons have used different kinds of materials that have often been the object of discussion. The aim of this study is to report our experience with augmentation septorhinoplasty, emphasising the type and nature of the...

Previous studies found that bone marrow (BM) allografts from DLA-identical littermates resulted in survival of two thirds of recipient dogs after otherwise lethal doses of 450 to 600 cGy of total body irradiation (TBI) because of successful allografts or autologous recovery after rejection of the allografts. The current study asked whether survival could be further improved by treating allograf...

Cell viability in peripheral blood progenitor cell (PBPC) grafts and its influence on the clinical course following transplantation was evaluated in 81 consecutive transplantations (72 autologous, 9 allogeneic) performed in patients with hematological diseases. Viability of cells in PBPC grafts immediately upon collection was 98.6 +/- 3.5%, after addition of dimethyl sulfoxide (DMSO) 73.3 +/- 2...

The efficacy of external vein wrapping of vascular grafts in promoting the development of a luminal endothelial surface was assessed in 12 dogs who underwent thoracoabdominal bypasses with 26-29 cm X 6-mm i.d. double-velour knitted Dacron grafts. In group I (n = 6) 6-cm segments of the grafts were wrapped with autologous jugular vein with its endothelial surface applied against the outside of t...

Forty patients underwent coronary revascularization using bilateral internal thoracic artery (ITA) grafts between 1988 and 1992. A total of 111 coronary grafts were performed, or an average of 2.8 grafts per patient. Each patient received bilateral ITA grafts, and in 20 patients an additional 29 grafts were constructed with 18 autologous veins and 11 gastroepiploic arteries. The right ITA was g...
