“Extension of the elbow is required to oppose gravity; however, activation of the triceps brachii is
frequently underestimated during the surgical planning for brachial plexus injuries. This report aims to describe a novel technique of distal nerve transfer designed RAD001 supplier for elbow extension reconstruction in patients sustaining a C5–C7 nerve root injury. We report a patient sustaining a brachial plexus injury with triceps palsy and preserved finger extension motion; after careful intraneural dissection of the radial nerve, a fascicle innervating the extensor digitorum communis muscle was sectioned, derouted and connected to a motor branch to the lateral head of the triceps. Eleven months after surgery, elbow extension strength scored MRC M4. No deficits on finger extension were observed. © 2011 Wiley Periodicals, Inc. Microsurgery, 2012. “
“Lipoprostaglandin E1 (lipo-PGE1) Carfilzomib cell line has been found accumulating in injured vascular regions. This study examined the localization of
lipo-PGE1 in the anastomotic region. The study was divided into three parts. First, we performed anastomosis of the rat femoral artery and vein (n = 17). Lipo-PGE1 labeled with 1,1′-dioctadecyl-1,3,3′,3′-tetramethyl-indocarbocyanine was infused intravenously. Hematoxylin-Eosin staining and fluorescence microscopic findings showed that lipo-PGE1 markedly accumulated at the anastomotic site when compared to the contralateral non anastomotic region. Then, we measured laser Doppler flow (LDF) of a lower leg before and after infusion of lipo-PGE1 (n = 7) and saline (n = 7). Increase of blood flow was maintained 1 hour after the infusion of lipo-PGE1 (144% ± 25.0%) when compared to saline infusion. Finally, we performed immunohistochemical and electron microscopic examinations
and found that Lipo-PGE1 was incorporated in vascular smooth muscle cells of the anastomotic region. These findings suggest selective accumulation of the lipo-PGE1 in the vascular Protein tyrosine phosphatase anastomosis site and affect on the blood flow of repaired vessels. © 2011 Wiley-Liss, Inc.

“Distal fingertip replantation is associated with good functional and aesthetic results. Venous anastomosis is the most challenging procedure. For replantation with an artery anastomosis-only procedure (no venous anastomosis), some protocols have been designed to relieve venous congestion involve anticoagulation and the creation of wounds for persistent bleeding. This report presents the authors’ experience of fingertip survival after artery anastomosis-only replantation with no persistent external bleeding. Twelve Tamai zone I fingertip total amputation patients who underwent artery anastomosis-only replantations were recruited from February 2009 to June 2012. Nerve repair was performed if identified. The patients were not subjected to conventional external bleeding methods.
