BACKGROUND: Despite early skepticism, the field of vascularized composite allotransplantation (VCA) has demonstrated feasibility. The ethics of VCA have moved past doubts about the morality of attempting such transplant to how to conduct them ethically. METHODS: Leaders of each program performing and/or evaluating VCA in the United States were invited to participate in a working group to assess the state and future of VCA ethics and policy. Four meetings were held over the course of 1 year to describe key challenges and potential solutions...

Vascularized composite allotransplantation for the forearm is a complex surgical procedure, requiring multidisciplinary collaboration. It is important to provide optimal blood flow to the grafts, effective immunosuppression, and early rehabilitation for graft survival and good functional outcomes. As ischemia-reperfusion injury and substantial but unquantifiable blood loss are inevitable in this type of surgery, anesthetic management should focus on providing adequate hemodynamic management with proper monitoring, and anesthetic and analgesic strategies to prevent vasoconstriction in the graft...

Vascularized composite allotransplantation represents a useful addition to reconstructive options available to the plastic surgeon. Though the procedure provides beneficial functional outcomes, there remain complications, often associated with the immunosuppression necessary to maintain an allograft. We report a case of eponychial fold lesions following successful bilateral upper extremity allotransplantation.

PURPOSE OF REVIEW: Vascularized composite allografts (VCA), which restore severely damaged body parts that cannot be repaired with conventional surgical techniques, often undergo acute skin rejection episodes in the early postgraft period. Although the risk of human VCA to be affected by chronic rejection was initially unknown, such cases were recently observed. RECENT FINDINGS: Chronic rejection targets preferentially the skin (dermal sclerosis, adnexal atrophy, necrosis) and vessels (graft vasculopathy) and may cause graft dysfunction, often resulting in ischemic graft loss...

In the past 20 years, reconstructive transplantation (RT) has emerged as a viable reconstructive option for carefully selected patients. More than 100 upper extremity and 40 face transplants have been performed worldwide to date. Concomitantly, the portfolio of reconstructive transplantation has been extended by additional procedures such as lower extremities, abdominal wall, neck, uterus, genitourinary, and pediatric transplants. In the present review article, we aim to summarize the current state of knowledge about this exciting field...

Introduction: Being able to counter immune-mediated rejection has for decades been the single largest obstacle for the progress of vascular composite allotransplantation (VCA). The human immune system performs the key role of differentiating the 'self ' from the 'non-self '. This, although is quintessential to eliminate or resist infections, also resists the acceptance of an allograft which it promptly recognises as 'non-self'. Materials and Methods: Pre-operative evaluation of the recipient evaluation included immunological assessment in the form of panel reactive antibodies (PRA), human leucocyte antigen (HLA) typing, donor-specific antibody detection assays (DSA) and complement-dependent cytotoxicity assays (CDC)...

In this repeated measures case study, we show that sensory deafferentation after limb amputation leads to changes in cortical somatotopic maps which are reversible after restoration of sensory input. Using magnetoencephalography (MEG), we observed in a child with bilateral hand transplants large-scale shifts in somatosensory lip cortical representation from anatomic hand area to anatomic face region. After recovery of tactile sensation in the digits, responses to finger stimulation were localized to orthotopic sensory cortex, but with atypical electrophysiologic features (amplitude and frequencies)...

The author summarizes briefly the history of hand allograft transplantation, the basics of the operative technics, and the medicinal treatment of the immunosuppression. He establishes that this operation requires complicated team-work: many specialists must be united in the interest of the successful final outcome. The biggest problem is not the technical challenge of the complicated operation, but the ineffectiveness of immunosuppression, its complications; even though significant development has happened in this field and experimental results are also encouraging...

English summary: Hand transplantation in Sweden - preparations under way Some patients with a uni- or bilateral hand- or forearm amputation cannot use a hand prosthesis, although high-tech prostheses have been developed. A hand transplantation, particularly for those with bilateral amputations, may be an alternative solution. In a hand-transplanted patient, grip function, strength, sensibility and subsequent improved quality of life can be restored. Risks related to immunosuppression must be balanced by expected benefits, and thorough selection of patients has to be performed from both medical and psychological point of view...

Hand loss can now be reversed through surgical transplantation years or decades after amputation. Remarkably, these patients come to use their new hand to skilfully grasp and manipulate objects. The brain mechanisms that make this possible are unknown. Here we test the hypothesis that the anterior intraparietal cortex (aIPC) - a multimodal region implicated in hand preshaping and error correction during grasping - plays a key role in this compensatory grasp control. Motion capture and fMRI are used to characterize hand kinematics and brain responses during visually guided grasping with a transplanted hand at 26 and 41 months post-transplant in patient DR, a former hand amputee of 13 years...

BACKGROUND: Immunosuppressive therapies derived from solid organ transplantation are effective in promoting survival of vascularized composite allotransplantation (VCA), but they cause serious side effects that are difficult to justify for this non-life-saving procedure. Unlike solid organ transplantation, hand and face transplants offer the possibility of site-specific immunosuppression for reducing systemic exposure while increasing intra-graft concentrations of the drug. Therefore, in this study, we tested whether a single intra-graft injection tacrolimus could promote VCA survival...

Overall, more than 60 hand/forearm/arm transplantations and 16 face transplantations have been performed in the past 12 years. In the European experience summarized here, three grafts have been lost in response to a vascular thrombosis (n = 1), rejection and incompliance with immunosuppression (n = 1) and death (n = 1). The overall functional and esthetic outcome is very satisfactory, but serious side effects and complications related to immunosuppression are challenges hindering progress in this field. The high levels of immunosuppression, skin rejection, nerve regeneration, donor legislation and the acceptance level need to be addressed to promote growth of this promising new field in transplantation and reconstructive surgery...

OBJECTIVE: To minimize maintenance immunosuppression in upper-extremity transplantation to favor the risk-benefit balance of this procedure. BACKGROUND: Despite favorable outcomes, broad clinical application of reconstructive transplantation is limited by the risks and side effects of multidrug immunosuppression. We present our experience with upper-extremity transplantation under a novel, donor bone marrow (BM) cell-based treatment protocol ("Pittsburgh protocol")...
