OBJECTIVE To compare the results of the root reconstruction with the aortic valve-sparing operation versus composite graft-valve replacement. METHODS From January 2002 to October 2013, 324 patients underwent aortic root reconstruction. They were 263 composite graft-valve replacement and 61 aortic valve-sparing operation (43 reimplantation and 18 remodeling). Twenty-six percent of the patients...

Chitin is a representative biomass resource comparable to cellulose. Although considerable efforts have been devoted to extend novel applications to chitin, lack of solubility in water and common organic solvents causes difficulties in improving its processability and functionality. Ionic liquids have paid much attention as solvents for polysaccharides. However, little has been reported regardi...

In more-distal amputations of the fingertips, microsurgical replantation is not feasible. For these cases, composite graft provides the best functional and ae...

OBJECTIVES We sought to delineate the effects of the severity of target lesions and their combinations on the occurrence of competitive flow, especially in the composite Y-graft and to establish an optimal strategy for graft arrangement and patient selection. METHODS We reviewed early and late angiograms of 2514 bypass grafts in 601 patients, who underwent off-pump coronary revascularization ...

BACKGROUND Administration of growth factors has been associated with increased viability of composite grafts greater than 1-cm in diameter. Platelet-rich plasma (PRP) contains many of the growth factors studied. In this study, we evaluate the effect of PRP injection on composite graft viability and the proper time for injection. METHODS A total of 24 New Zealand White rabbits were divided int...

Objective Composite graft of left internal thoracic artery and great saphenous vein in revascularization of the left coronary system is a technique well described in literature. The aim of this study is to analyze blood flow dynamics in this configuration of composite graft especially in what concerns left internal thoracic artery's adaptability and influence of great saphenous vein segment on ...

BACKGROUND Among the various methods for correcting nasal deformity, the composite graft is suitable for the inner and outer reconstruction of the nose in a single stage. In this article, we present our technique for reconstructing the ala and columella using the auricular chondrocutaneous composite graft. METHODS From 2004 to 2011, 15 cases of alar and 2 cases of columellar reconstruction em...

INTRODUCTION Chronic laryngotracheal stenosis (LTS) remains a challenging problem for otolaryngologists. A composite hyoid bone interposition graft has the potential to be an ideal graft because the head and neck surgeon can obtain the graft in the same operative field with good vascular supply from the muscle pedicle. METHODS A composite hyoid interposition graft was used to provide structur...
