Background: Microsurgical reconstruction is employed for complex plastic surgery problems when other options don't seem to be satisfactory either functional or aesthetic Aim: to evaluate sleeve suture technique and oblique cut technique in end-to-end micro-anastomosis of vessels with size discrepancy in a Rat model regarding patency of the anastomosis and feasibility of the technique
Methods: Thirteen Samples were included in this study and randomly assigned to either Group Ι (Sleeve suture technique) or Group Ι (Oblique cut technique). The main assessment parameters were anastomosis patency, time of anastomosis, and the number of suture units. Other parameters included anaesthesia consumption, thrombosis rate, and leakage after anastomosis.
Results: Nearly equal patency rates have been found in the two techniques in the animal model, although the invagination technique was faster and technically simpler to perform with less suture unit consumption. The oblique cut technique showed a highly statistically significant increase in the anastomosis time and an increased in sutures number in comparison to the sleeve technique plus the necessity to flip-flop the wall for posterior wall suturing.
Conclusion: No patency advantage of one technique over the other. However, in the experimental model used, it was found that the invagination technique was faster and technically simpler to perform. Flow-through the invagination was nearly equal to that through the oblique cut end-to-end.
