Abstract

One carotid from each dog underwent a laser anastomosis and the other carotid an interrupted suture repair. One or eight weeks later (n ≥ 4 dogs/time period); four rings (1 mm in length) containing the laser or suture anastomosis or the normal artery (two/dog) were removed. Using a photoelectric force transducer and lever system, the ring was stretched in increments and passive force measured. At each length, the arterial muscle was stimulated and active force measured. The mean laser and control passive length/tension (L/T) curves were not different (P > 0.05), but the suture curve was shifted downward (P < 0.05). The mean laser and suture active L/T curves were similar at 1 week (> 0.05) and lower than the control curve (P < 0.04). At 8 weeks, the laser-repaired vessels produced an active force similar to control muscle (P > 0.05) but the suture repairs could not generate this active force (P < 0.05). These data suggest that the laser repair and normal artery are more mechanically compatible than the suture repair as studied by this method.
