ABSTRACT

Introduction: Students in vascular surgery and microsurgery courses in the departments of experimental surgery of the Instituto Nacional de Enfermedades Respiratorias and the Instituto Nacional de Ciencias Médicas y Nutrición “Salvador Zubirán” use plastic tubes with different caliber as didactic material to perform vascular anastomosis. This plastic material has very different texture when is compared to an actual blood vessel. Objective: To evaluate the usage of preserved arterial segments in the training of surgical and microsurgical procedures of vascular anastomosis. Material and methods: Canine arterial segments with variable diameter were obtained from thoracoabdominal aorta, pulmonary artery, femoral arteries and carotid arteries. All arteries were preserved. Students performed vascular anastomoses using preserved arteries and they answered some questions about texture, consistency and the force of the suture through the wall of the preserved vessel in comparison with a normal vessel. Results: Thirty-six arterial segments were obtained; 18 arteries were preserved using dried-freezing and 18 were cryopreserved; then, 1-cm segments were obtained and randomly supplied to the students for the vascular anastomosis procedure. They were asked if these vessels had consistency and texture similar to a normal vessel and which was more resistant. Conclusion: The preserved arterial segments demonstrated to be a suitable biological material for surgical or microsurgery training that presented both texture and consistency similar to normal vessels.
