Modelo experimental de fraturas de costelas e proposição de dispositivo para ancoragem de suturas de estabilização costal – comparação (ex vivo) da abordagem cirúrgica convencional com a vídeo-cirúrgica

Abstract

Chest trauma is an affection of a common occurrence in the emergency care of small animals, being caused by blunt or penetrating trauma to the chest wall, with the possibility of injury to ribs and / or soft tissues (muscles and viscera), being open or open. The aim of this study was to develop a minimally invasive surgical method for video-assisted thoracoscopy and CTVA (Video Assisted Thoracic Surgery) for the reduction and stabilization of rib fractures in dogs and cats. A study was carried out on anatomical revision, definition of the videothoracoscopic approach and evaluation of the model of fracture of ribs, being 5 experiments in stages (cadavers of dogs); Phase 2 - Post mortem experimental analysis - was performed in two stages: 1 st Stage - Development, standardization and training of the circumferential suture technique, for reduction and stabilization of rib fractures, associated or not with video surgery, using 2 experimental units in this stage; 2nd Stage - Experimental use of the proposed technique (circumvector sutures), requiring 10 experimental units of any size, age and gender. These were numbered according to the purchase, having undergone a series of techniques at both levels, although they were not tested by pairs, and were not made by us, and not by the right hemithorax, by CTVA techniques. The inverse was used as one of the experimental models of experimental partitioning, with a technique of application in both forms, with the aim of comparing a traditional blind version with a use of videurgical methods. We conclude video-rendering of the circumflex chains, allowing the occurrence of iatrogenic lesions, such as the conventional (blind) execution occurrences, and the circumscribed sutures in association with the polyvalent costal stabilization device, allowed the adequate reduction and stabilization of fractures of ribs, by minimally invasive approach by transdiaphragmatic paraxiphoid thoracoscopy, in order to promote less trauma and operative morbidity in this type of surgical work.
