Abstract
ObjectiveThe purpose of this investigation was to test a modified telescopic anastomosis in large muscular arteries. Material and methodsThe right carotid arteries in 30 sheep (average weight 57±5.7kg) were transected and anastomosed end to end using two guided sutures and compared with a control group (10 sheeps) using two external sutures (Lauritzen method). ResultsThe mean time to complete the anastomosis (4.5min) and hemostasis (4.3min) in the experimental group was less than the control group (17.3min for anastomosis and 6.4min for hemostasis) (P<0.05). In addition, the total amount of blood loss during the modified anastomosis was significantly lower than Lauritzen method (3.8 versus 8ml). In both experimental and control groups the scanning electron microscopy (SEM) at 90th day post-operation revealed a continuous smooth layer of endothelial cells covering the anastomotic junction. ConclusionsAnastomosis with two guided sutures is easy and faster to perform and could be applicable to an acutely transected vessel.
