Reparação da traquéia de cã o com segmaneto muscular homólogo de diafragma conservado em glicerina a 98%

Abstract: A viabilidade de segmento muscular de diafragma homólogo conservado em solução de glicerina a 98% foi estudada na reparação da traquéia cervical de cães. Foram utilizados 18 cães, adultos, oito machos, sem raça definida com peso variando de 6 a 21kg. Cinco anéis traqueais (2,0 x 4,5cm) foram removidos parcialmente para implantação de segmento muscular homólogo. Os animais foram separados em grupos de igual número e observados por um período de 15 dias (grupo I), 30 dias (grupo II) e 60 dias (grupo III) de pós-… Show more

“…The production of fibrin, in addition to promoting adherence to the wound, stimulates the migration of defense cells such as leukocytes, macrophages, neutrophils, and fibroblasts, which are important in local collagen deposition 15 . The healing process of maturation in the injured area leads to contraction of the tissue edges, which causes retraction and consequent intraluminal decrease in hollow organs 16 . Such information justifies the exuberant granulation and stenoses identified by tracheoscopic examination and is compatible with the phases and physiological processes of healing.…”

“…Repair of the tracheal defect is an important characteristic of the preservation of the biomechanics of the organ and maintenance of air flow by the different pressures exerted during breathing. The use of homologous muscle grafts or tridimensional fabrication prostheses proved to be efficient at the implanted site, supporting intratracheal pressure and preventing organ collapse 16 , 17 . Through tracheoscopy, it was possible to observe a low rate of tracheal stenosis in the operated animals, and, even when present, they did not show severe impairment of respiratory function or survival in the evaluated time.…”

“…A glicerina a 98% têm sido utilizada nas quatro últimas décadas para conservar diferentes tecidos como dura-máter (PIGOSSI et al, 1964), peritônio bovino e canino (DALECK et al, 1992), pericárdio eqüino (RANZANI et al, 1990), diafragma e bexiga caninos (MAZZANTI et al, 2000;OLIVEIRA et al, 2000) entre outros. A glicerina 98% proporciona desidratação celular e atua contra fungos e bactérias gram-negativas e positivas, com exceção das formas esporuladas (PIGOSSI, 1967).…”
