AIMS The objective of the present study was to report our ongoing prospective cohort of autograft recipients with up to 21 years of follow-up. METHODS AND RESULTS All consecutive patients (n = 161), operated between 1988 and 2010, were analysed. Mixed-effects models were used to assess changes in echocardiographic measurements (n = 1023) over time in both the autograft and the pulmonary allog...
STUDY DESIGN A retrospective 1-year cost-utility analysis. OBJECTIVE To determine the cost-effectiveness of using recombinant human bone morphogenic protein (rhBMP-2) in addition to autograft for 1- and 2-level lumbar fusions. SUMMARY OF BACKGROUND DATA rhBMP-2 has been studied extensively to identify its benefits, risks, patient outcomes, and costs relative to autograft [local bone or ilia...
BACKGROUND Anterior cruciate ligament (ACL) reconstruction with hamstring autografts less than 8.5 mm in diameter is associated with worse patient-reported outcome scores and increased risk of revision surgery compared with reconstructions performed with larger grafts. One proposed solution to small autograft harvest is to create a hybrid graft by augmenting autografts with allograft tissue to ...
STUDY DESIGN Fusion success with rhBMP-2 and autograft in titanium or PEEK corpectomy devices was evaluated in a sheep lumbar corpectomy model. The 6 treatment groups included titanium mesh or PEEK corpectomy devices filled with rhBMP-2 on a compression-resistant matrix (CRM) carrier; rhBMP-2 in a morselized absorbable collagen sponge (ACS) carrier combined with resorbable ceramic granules; and...
BACKGROUND Autograft regurgitation and root dilatation after the Ross procedure is of major concern. We reviewed data from the German Ross Registry to document the development of autograft regurgitation and root dilatation with time and also to compare 2 different techniques of autograft implantation. METHODS AND RESULTS Between 1990 and 2006 1014 patients (786 men, 228 women; mean age 41.2+/...
We reviewed 29 patients who had undergone intercalary resection for malignant tumours. Of these, 14 had received segmental allograft reconstruction and 15 extracorporeally-irradiated autograft. At a mean follow-up of 71 months (24 to 132), 20 were free from disease, five had died and four were alive with pulmonary metastases. Two patients, one with an allograft and one with an irradiated autogr...
Introduction Large, segmental, osseous defects remain a major clinical problem. Common approaches to healing such defects include the use of autograft bone and the application of recombinant, human bone morphogenetic protein-2 (BMP-2) in the form of InfuseTM. Neither, however, is ideal. Supplies of autograft are limited and its harvest can be associated with considerable morbidity. BMP-2 is ext...
AIM The purpose of this study is to determine the outcome and complications of pregnancy in women with pulmonary autograft valve replacement for aortic valve disease. METHODS AND RESULTS The records of all women who had undergone pulmonary autograft valve replacement at the National Heart Hospital (now Royal Brompton Hospital) since 1968 were reviewed. From 1968 to 1993, 27 hospital survivors...
OBJECTIVE We performed a review of a consecutive series of 487 patients undergoing the Ross operation to identify surgical techniques and clinical parameters that affect outcome. METHODS We performed a prospective review of consecutive patients from August 1986 through June 2002 and follow-up through August 2004. Patient age was 2 days to 62 years (median, 24 years), and 197 patients were les...
OBJECTIVE To calculate clinical guidelines for the optimal location and size of a rotational autokeratoplasty. METHODS The ideal graft size and trephine decentration for a rotational autograft were calculated based on scar location using geometric models. Mathematical variables were set to maximize postoperative visual acuity and for generalization of the geometric model. This model was used ...
