Estudo comparativo entre sutura manual e mecanica de coto br？nquico em c？es submetidos à pneumonectomia esquerda: avalia？？o histopatológica do pulm？o direito e avalia？？o eletrocardiográfica

the study had purpose to evaluate the possible electrocardiographical alterations and the histopathological alterations in the lung of dogs submited by left pneumonectomy with comparative approach between two types of suture of bronchial stamp (manual and mechanical). we used twelve dogs, males and females, adults, mongrel dogs, weighting between 15 and 20 kilograms and evaluated the macroscopic alterations of right lung and the alterations of electrocardiogram. all animals showed clinical condition satisfactory in the post operated time. the electrocardiographical alterations were deviation of cardiac axis, sinoatrial block and miocardial isquemia. the histopathological alterations were pulmonary atelectasis, proliferations of bronchiole epithelium tended to obliterations and pulmonary emphysema. the study suggested that right lung was submited to pulmonary hipertension.
