Resumo

Foi realizada a avaliação morfológica da veia cefálica submetida à pinçamento em cinco
equinos hígidos. Foram testadas as pinças hemostáticas: Diffenbach bulldog, De Bakey
bulldog, Rochester reta e De Bakey com cremalheira. Após 15 minutos da aplicação das
referidas pinças, foi realizada a flebectomia parcial e coletadas as amostras referentes a cada
segmento do vaso pinçado e do segmento controle sem pinçamento. Das peças procedeu-se as
preparações histológicas dos segmentos da veia nas colorações de Hematoxilina-Eosina e
Tricrômio de Masson. Os cortes histológicos foram avaliados por microscopia óptica. Foi
realizada análise morfológica das veias, utilizando para isto uma escala de avaliação de lesões
vasculares após pinçamento. As pinças com serrilhamento transversal e fechamento tipo
cremalheira causaram as maiores alterações, observou se marcada vacuolização das células
musculares e desarranjo na túnica media com perda marcada das células endoteliais da túnica
intima do vaso estudado
