Abstract

Objective: To observe the time required for anastomosis and the reliability for pressure tolerance after internal mammay artery (IMA)-coronary artery anastomosis. Method: Eight sheep underwent thoracotomy and left IMA harvest. In group I (T) the IMA were anastomosed to left anterior descending artery (LAD) with 7-0 prolene suture (n=4) and in group II (LA) IMA were anastomosed to LAD with laser. Result: The time required for laser technique was shorter than that required in suturing technique [117.5±39.48min (total) and 38.25±6.23 min vs 62.5±37.83 min (total) and 20±6.53 min respectively] (p<0.01). Prior to closing thoracotomy both two groups endured the impact of pharmacologic vasopressor. No leakage at the anastomosed site was observed in both groups. After the closure of thoracotomy, well tolerance for both adrenalin and thoracic negative pressure was observed in the two groups. The peak systolic pressure induced by pharmacologic agent was similar in both groups. Neither stenosis nor thrombus or embolism was observed and immediate patency rate in both groups was 100%. Conclusion: Laser assisted technique seems to be favorable for patency rate and could lead to better result after coronary artery bypass grafting (CABG).
