BACKGROUND The failure of a kidney transplant is now a common reason for initiation of dialysis therapy. Kidney transplant recipients commencing dialysis have greater morbidity and mortality than transplant-naïve, incident dialysis patients. This study aimed to identify variables associated with survival after graft failure. METHODS All recipients of first, deceased donor kidney transplants p...
BACKGROUND It remains disputed whether cardiac retransplantation should be performed. This study aimed to evaluate our long-term experiences on cardiac retransplantation in adults. PATIENTS AND METHODS Between March 1989 and December 2004, 2% (28/1290) of cardiac retransplantations were performed. RESULTS The reasons for cardiac retransplantation were cardiac allograft vasculopathy (n=13; 4...
Although numerous studies over the past 40 years have addressed this problem, initial graft failure is still a key question in clinical lung transplantation. As a possible tool to avoid and treat initial graft failure after lung transplantation, laboratory evidence and clinical reports currently emphasize the role of substitution therapy of surfactant combined with inhaled nitric oxide.
conclusions using 3d ct scan to produce a prototype and reconstruct the mandible with a custom-made ti-mesh tray was useful. patient was followed up for 14 months. mandibular deviation was largely corrected. there was no complication in the donor site. no sign of extra or intra oral fistula, dehiscence or infection was detected. ti-mesh technique has three major advantages over other methods: i...
BACKGROUND Reliable data regarding absolute and relative risks of death and graft failure after coronary artery bypass graft surgery (CABG) and percutaneous coronary intervention (PCI) in renal transplant patients are unavailable. METHODS AND RESULTS Renal transplant patients undergoing inpatient CABG (n=1400) or PCI (n=4097) were identified from United States Renal Data System data. Cumulati...
BACKGROUND In contemporary coronary artery bypass graft (CABG) surgery, the association between symptomatic graft failure (GF) and long-term clinical outcome remains unclear. We sought to identify the clinical characteristics and outcomes of GF in symptomatic patients requiring cardiac catheterization within 1 year of CABG surgery. METHODS Using the Alberta Provincial Project for Outcomes Ass...
Objective: Survival after heart transplantation has improved significantly over the last decades. There are a growing number of patients that require cardiac retransplantation because of chronic allograft dysfunction. With regard to the critical shortage of cardiac allograft donors the decision to offer repeat heart transplantation must be carefully considered.Methods: Since 1983 a total of 807...
PURPOSE The aim of the present study was to compare primary stability in ACL reconstruction and ultimate load to failure of a mesh augmented hamstring tendon graft fixed with two cross pins to established hamstrings and bone-patellar-tendon-bone (BTB) graft fixation methods. METHODS Forty fresh porcine femora were divided into four groups: (A): BTB graft fixed with two RigidFix® pins, (B): ha...
This study analyzed the characteristics of 257 HLA-identical sibling transplants of granulocyte colony-stimulating factor-mobilized peripheral blood progenitor cells depleted of T cells by CD34(+) positive selection (allo-PBT/CD34(+)) for their effect on the incidence of graft failure. Twenty-four patients developed graft failure (actuarial probability, 11%; 95% confidence interval, 7.1-14. 9)....
BACKGROUND Recurrent anterior shoulder instability after coracoid process transfers may be caused by trauma, sports injury, or technical failure of the index procedure. Surgical techniques vary with regard to graft orientation and positioning and number of screws utilized for fixation. PURPOSE To identify surgical and patient-related factors associated with failure, defined as the need for re...
