Background: Fat grafting is a common procedure in plastic surgery. A major limitation is unpredictable graft retention, in part caused by inadequate oxygen delivery during the early posttransfer period.
Methods: The authors present a bioengineered approach to the design of a fat graft based on mathematical theory, which can estimate the limitations of oxygen delivery.
Background: Fat grafting is a common procedure in plastic surgery but associated with unpredictable graft retention. Adipose tissue (AT) "product" quality is affected by the methods used for harvest, processing and transfer, which vary widely amongst surgeons. Currently, there is no method available to accurately assess the quality of AT.
View Article and Find Full Text PDFFat grafting is a common procedure in aesthetic and reconstructive plastic surgery, but variable graft retention limits its utility. Unpredictable clinical outcomes with fat grafting can be explained in part by the lack of standardized protocols for harvesting, processing, and transplanting adipose tissue (AT). Historically, plastic surgeons have relied on trial and error and their clinical experience to develop fat grafting protocols.

However, at present there are no consistent guidelines for volunteer groups in plastic surgery seeking to provide high-quality and safe care.
Methods: With these quality and safety standards in mind, in 2006, the Volunteers in Plastic Surgery Committee of the American Society of Plastic Surgeons/Plastic Surgery Educational Foundation undertook a project to develop a detailed set of guidelines for volunteer groups from developed countries seeking to provide plastic surgery services to children in developing countries.
Background: Surgical digital artery sympathectomy is indicated when medical management has failed to control rest pain, impending infarction of digits, or healing of ischemic ulcerations caused by profound vasospasm that is associated with other systemic diseases. After digital artery sympathectomy, recurrence or persistence of vasospasm may compromise hand function and ultimately result in amputation of all or portions of both lower and upper extremities.
Methods: The authors present a case series of 11 patients with vasospasm producing intractable rest pain, digital ulcerations, and digit infarctions that failed aggressive medical therapy and that were then treated by perivascular injections of botulinum toxin A (Botox).
