“…Determination of when early motion may be started, following vascular anastomoses near the joints of fingers and other extremities, and the evaluation of tensile strength and thrombus formation at the anastomotic site, is very important. Tensile strength at the anastomotic site has been measured previously in various sutured anastomoses [10][11][12][13][14][15][16] ; however, reports of tensile strength in mechanical anastomoses are few. 17,18 Gilbert and colleagues 17 compared the Unilink anastomotic system with standard suture techniques in terms of anastomotic strength, under conditions of uniaxial loading following Unilink and suture anastomosis of both carotid arteries and facial veins in rabbits.…”

The purpose of this study was to evaluate whether early motion following mechanical anastomosis using a biodegradable ring device was possible or not, by measuring tensile strength and the rates of thrombus formation at anastomotic sites. Bilateral femoral arteries and veins of 24 rabbits were repaired by sutured anastomoses and biodegradable ring anastomoses. The tensile strength of the anastomotic site was measured by constant loading with a material-testing machine, using specimens excised at 24 hr, 72 hr, 1 week, and 2 weeks after anastomosis. The tensile strength of biodegradable ring arterial anastomoses was significantly stronger than sutured anastomoses at 24 hr, 72 hr, 1 week, and 2 weeks. No statistically significant differences were observed in venous anastomoses at any interval. In separate experiments, biodegradable ring anastomoses and sutured anastomoses of the bilateral femoral arteries of 18 rabbits were constructed, and early passive knee motion was carried out at 100 times once a day with maximum spreading of the hip joint for 24 hr, 72 hr, and 1 week. Thrombus formation at the anastomotic sites was evaluated by scanning electron microscope (SEM). SEM showed no thrombus formation in the biodegradable ring anastomoses at any interval; however, thrombi were observed in the sutured anastomoses (33 to approximately 50 percent).

Using the scanning electron microscope (SEM), we compared the areas of endothelial disruption 45 minutes after penetration of rat femoral and carotid artery walls with 75- and 100-mu taper point and taper cut microsurgical needles, with and without restoration of blood flow. Four experimental groups were designated: needle puncture only, single loose, suture loop, end-to-end anastomosis, and end-to-side anastomosis. The vessels were perfused with normal saline, immersed in 3% buffered glutaraldehyde, and mounted under slight tension to simulate physiological wall distention before SEM examination. Endothelial craters at vessel puncture sites were measured on SEM photomicrographs at 300 X magnification. All vessels were patent when examined. Crater diameters averaged less than double the needle size. Although taper cut needles produced craters that were 25% larger (P less than 0.05), vessel penetration was easier than with the taper point needle and bleeding times were the same. Suture loop produced craters that were 36% larger (P less than 0.05) than needle puncture alone. Craters were 20% larger when blood flow was restored and 50% larger in the femoral than in the carotid artery. Although craters seen after end-to-end anastomosis were not significantly larger than those after end-to-side anastomosis, interrupted sutures appeared to cause more endothelial damage than continuous sutures. These results suggest that the use of cutting needles, passage and tying of sutures, vessel distention by blood flow, and suturing of more muscular and less elastic vessel walls (femoral artery) may increase endothelial disruption but do not reduce patency.
