The left carotid artery of 12 Sprague-Dawley rats was sectioned and anastomoses immediately performed utilizing a new technique termed coupled suturing. Patency and constriction were assessed immediately postoperatively and at 1, 2, and 3 weeks. Specimens were also evaluated by light microscopy and

β¦ Synopsis
This study describes our experience using an improved technique for microsurgical sleeve anastomosis of arteries. Modifications of previously described techniques include utilization of a sidecut and placement of the two stitches within separate vertical planes. In 40 arteries, we attained a patency rate of 97.5%. Histology, in vivo observation, and flow study using high-frequency pulsed ultrasound Doppler at 2 hr to 8 weeks demonstrate that the sidecut sleeve anastomosis shows patency and flow characteristics similar to those of standard end-to-end anastomosis, but with a dramatic decrease in operative time.

The ring technique for end-to-side microvascular anastomosis employs a resorbable polyglycolic acid ring to prevent stenosis and spasm at the anastomotic site. In 20 rats, the ring technique was compared with the conventional technique for constructing end-to-side anastomoses between the femoral (0.
A new rearterialized orthotopic liver transplant (OLT) model in the rat is described. The model involved performing a novel sleeve anastomosis technique for graft rearterialization which consisted of three extraluminal suture anastomoses between the recipient's proper and the donor's common hepatic
Microsurgery is a valuable discipline performed in many surgical practices. In literature, hundreds of studies dealing with different aspects of microsurgical practice including studies about new agents for anastomosis, different suturing materials and methods plus new models for surgical training,
