| Popis: | Background This study aimed to confirm the feasibility and reliability of saphenous artery (SA) and great saphenous vein (GSV) anastomosis as a new supermicrosurgery training model and to compare the one-way-up anastomosis with the currently used end-to-end anastomosis technique. Methods Twenty supermicrosurgical anastomoses were performed in 10 Sprague Dawley rats. The external diameters of SA and GSV were measured using Leica LAS EZ software. The right-side SA and GSV anastomoses were performed using the standard end-to-end anastomosis technique. The left-side SA and GSV anastomoses were performed using the one-way-up technique with 11–0 monofilament-interrupted sutures. The duration of the surgery, patency rates, and technical challenges of the two anastomoses methods were compared. Results The mean external diameters of SA and GSV were 0.273 ± 0.03 and 0.291 ± 0.02 mm, respectively, which qualify these vessels for supermicrosurgical training. The vessels were easily accessible and both anastomosis techniques were feasible. The one-way-up technique was proven to be faster as compared with the end-to-end anastomosis technique (artery: 34 ± 2.55 vs. 40.4 ± 2.97 minutes, p = 0.02; and vein: 37 ± 4.85 vs. 44 ± 2.35 minutes, p = 0.05, respectively). Short-term patency rates for arteries and veins were 100% for both techniques. Seven-day anastomosis patency rates for arteries and veins were 80 and 100% for the end-to-end technique and 100 and 80% for the one-way-up technique, respectively. Conclusions We confirmed that saphenous pedicle is suitable for creating a supermicrosurgery training model for practicing the ultrafine motor skills. To the best of our knowledge, this is the first report on supermicrosurgery of SA and GSV in the rat model. |
