“Background: Free tissue transfer in reconstruction of lower extremity wounds is well established. Controversy surrounds type and regimen of intravenous fluid application during microsurgery. Hemodilution is supposed to influence haemostatic process. Patients and Methods: We performed an analysis of 48 patients treated with a free latissimus dorsi muscle flap to the lower leg for posttraumatic soft-tissue coverage. Postoperative latissimus dorsi muscle flap perfusion was controlled by clinical monitoring.
Intraoperative infusion management was evlatuated retrospectively. Results: In 4 of 48 included patients, a complete buy Target Selective Inhibitor Library loss of free latissimus dorsi muscle flap was registered. Concomitant increased saline infusion was detected (4,534 ml versus. 6,125 ml; P = 0.048). Similar findings for relation of total infusion volume to body weight were seen (44 ml/kg versus 69 ml/kg; P = 0.01). No significant colloid infusion was detected. Conclusions: We demonstrate the clinical relevance of extensive intraoperative hyperhydration, which can provoke
a complete free flap loss. © 2010 Wiley-Liss, Inc. Microsurgery, 2010. “
“Cellular and vascularized bone marrow cells have been PLX4032 used to induce donor-specific chimerism in various models of composite tissue allotransplantation. Although thymus transplantation has been reported in the literature, the effect of thymus transplantation on chimerism
levels in vascularized bone containing composite tissue allotransplantation has not been reported. In this study, a new method for composite vascularized sternal bone marrow transplant model is descried that can be applied to augment chimerism after transplantation. A total of seven composite osseomusculocutaneous sternum, ribs, thymus, pectoralis muscles, and skin transplantations were performed in two groups. The first group (n = 5) was designed as an allotransplantation group and the second group (n = 2) was designed as an isotransplantation group. Composite osseomusculocutaneous sternum, ribs, thymus, and pectoralis muscles allografts Carnitine palmitoyltransferase II were harvested on thecommon carotid artery and external jugular vein and a heterotopic transplantation was performed to the inguinal region of the recipient rat. Cyclosporine A monotherapy was administered in order to prevent acute and chronic allograft rejection. Animals sacrificed when any sign of rejection occurred. The longest survival was 156 day post-transplant. Assessment of bone marrow cells within sternum bone component and flow cytometry analysis of donor-specific chimerism in the peripheral blood of recipients were evaluated. Our results showed that thiscomposite allograft carried 7.5 × 106 of viable hematopoietic cells within the sternum component.
