Results: The mean functional fibrinogen to platelet ratio was significantly higher in the surgery group compared to healthy volunteers. Of the 29 patients studied, 31% (n = 9) had some form of thrombotic event, with all but one patient having a ratio ≥42% (mean 47% ± 7%). For those patients without thrombotic events, the mean ratio was 37% ± 5%. Conclusion: A functional fibrinogen to

platelet ratio above 42% as measured by TEG® may be useful in identifying those patients likely to develop thrombotic complication. © 2012 Wiley Periodicals, Inc. Microsurgery, BI 6727 mw 2012. “
“The effect of microsphere delivered Nerve Growth Factor (NGF) in a poly-lactic-co-glycolic-acid (PLGA) 85/15 nerve conduit bridging a 10mm rat sciatic nerve gap was assessed, comparing nine groups (n = 6): PLGA conduits filled with saline, saline and NGF, saline with blank microspheres; four different NGF microspheres (5, 20, 50, and 100 mg/ml); an autologous graft and sciatic nerve gap. Histomorphometry, retrograde tracing, electrophysiology, and functional outcomes were evaluated up to 16 weeks. The autologous graft showed the largest fascicular area (0.65 mm2) and had a significantly greater number of myelinated fibers (P < 0.0001). Electrophysiology showed Compound Muscle Action Potential (CMAP) recordings Target Selective Inhibitor Library datasheet for the autologous graft returning at 6 weeks after nerve transection, reaching their highest amplitude of 3.6 mV at endpoint. No significant

differences were found in functional evaluation between groups or between conduits with microspheres and the saline filled conduit. A PLGA 85/15 nerve conduit is capable of sustaining nerve regeneration. The microsphere delivery system does not interfere with regeneration. © 2011 Wiley-Liss, Inc. Microsurgery 2011. “
“Chylous reflux is a

rare disorder in which chyle flows antidromically from its normal route to the extremities, thorax, abdominal cavity, or other parts of the body. We present a case of chylous reflux with megalymphatics in a 28-year-old boy who presented chylorrhea in the foot, leg, and external genitalia, lymphedema, and hemangioma in the affected limb. Lymphaticovenous shunts using subcutaneous vein grafts with valves were applied these to the patient for treatment of repeated chylorrhea. After surgery, the patient has not complained of chylorrhea and been freed from conservative physiotherapy such as bandaging or application of compression stockings for lymphedema for two years. A subcutaneous vein graft with valves may be considered a useful method as a shunt between incompetent and dilated lymphatics and veins instead of a saphenous vein graft in the treatment of chylous reflux in lower extremities. We discuss these treatments based on the literature about chylous disorders. © 2010 Wiley-Liss, Inc. Microsurgery 30:553–556, 2010. “
