A fifty eight year old man with Marfan's syndrome and an aortic composite graft with a Björk-Shiley mechanical prosthesis presented with a large aortic root abscess caused by Staphylococcus aureus endocarditis. Despite extensive surgical debridement and implantation of an aortic homograft as a composite graft, early postoperative transoesophageal echocardiography continued to demonstrate a larg...
Composite endpoints that not only encompass mortality and relapse, but other critical post-transplant events such as graft-versus-host disease, are being increasingly utilized to quantify survival without significant morbidity after allogeneic blood or marrow transplantation. High-dose, post-transplantation cyclophosphamide reduces severe graft-versus-host disease with allogeneic marrow transpl...
BACKGROUND Acquired nasal stenosis poses a reconstructive challenge for the facial plastic surgeon. Many surgical options are available, ranging from primary closure to skin grafts to free flap reconstruction for complex defects. The free auricular composite graft is a single-stage procedure that can be used to repair nasal vestibular stenosis causing nasal obstruction. CASE REPORT We present...
Vascularized composite allotransplantation (VCA) is an effective treatment option for patients suffering from limb loss or severe disfigurement. However, postoperative courses of VCA recipients have been complicated by skin rejection, and long-term immunosuppression remains a necessity for allograft survival. To widen the scope of this quality-of-life improving procedure minimization of immunos...
Introduction: Posterior reduction probably reduces only the periphery of the endplate with its strong annular attachments while the central area remains depressed allowing for efficient realignment of the spine, direct and indirect decompression. With distraction force, restoration of vertebral body height and partial clearance of bone or discal fragments from within the spinal canal by ligamen...
OBJECTIVE We report a case in which an avulsion-amputation of the thumb proximal to the lunula was repaired by reattaching the amputated segment as a composite graft. The graft demonstrated complete survival with only a minimal sacrifice in length. METHODS A 23-year-old man presented 4 hours after an avulsion injury of the thumb with associated distal and proximal phalanx fractures. The amput...
BACKGROUND This article presents long-term outcomes after correcting secondary bilateral cleft lip nasal deformities using a refined reverse-U incision and V-Y plasty or in combination with a composite graft in order to elongate the short columella. METHODS A total of forty-six patients underwent surgery between September 1996 and December 2008. The age of the patients ranged from 3 to 19 yea...
OBJECTIVE To evaluate the efficacy of using hyperbaric oxygen to enhance auricular composite graft survival via a prospective, randomized, placebo-controlled, double-blind study. DESIGN Eighteen New Zealand White rabbits were randomly assigned to treatment (n = 9) and control (n = 9) groups after amputation and reattachment of 20 x 10-mm auricular composite grafts. The treatment group receive...
BACKGROUND Screws placed in the distal fibula may not have satisfactory purchase during internal fixation of an osteoporotic ankle fracture. Tibia-pro-fibula screws that extend from the fibula into the distal tibial metaphysis provide additional purchase. The purpose of this study was to investigate if purchase of these screws can be enhanced further by injecting calcium sulfate and calcium pho...
BACKGROUND Simultaneous pancreas and kidney transplantation is the treatment of choice for diabetes mellitus patients with associated end-stage renal disease. Limited vascular access could be encountered in patients with severe atherosclerosis, and/or severe obesity and in re-transplant patients. We describe a modified technique that facilitates simultaneous pancreas and kidney (SPK) composite ...
