- Microsurgical arterial anastomosis in young and adult rats: an evolutive and comparative study(2022) SANTOS, Maria Merces; TANNURI, Ana Cristina Aoun; LACERDA, Adriana Vasconcelos; GONCALVES, Josiane de Oliveira; RICARDI, Luiz Roberto Schlaich; TANNURI, UenisPurpose: To evaluate the caliber of an arterial micro-anastomosis in the young growing animal using a continuous suture technique. Additionally, late morphological changes and blood flows distal to the anastomosis were evaluated. Methods: Seventy-four Wistar rats were submitted to laparotomy to access the aorta for blood flow measurement. The aorta was sectioned using microsurgery technique and an end-to-end anastomosis with continuous suture. After a period of six months to one year, the anastomosis was checked. Results: Regarding the size of the aortas, comparing the pre- and postoperative values, there was an increase of 13.33% in adult animals and 25% in young animals, without any difference in the blood flows. Conclusion: The arteries of young rats show signs of growth at the site of the anastomosis performed with continuous suture.
