Abstract
The bursting and tensile strength of laser-assisted anastomosis (LA) was assessed and compared with conventional suture anastomosis (CA) using a standard rabbit carotid artery model.
LA arteries demonstrated lower bursting strengths than those of CA controls, with significant differences at 3 days (p<0.01). LA arteries anastomosed with 3 stay sutures demonstrated lower bursting strengths than 4 or 5 stay sutures at 1 hour (p<0.01). These results may explain the late aneurysm formation. Additional stay suture seemed to prevent such complication.
LA arteries consistently demonstrated lower tensile strengths than those of CA with significant differences at 1 hour, 3 days(p<0.01), and 7 days(p<0.05).
