Summary: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. O presente estudo teve como objetivo avaliar as possíveis alterações eletrocardiográficas e as alterações histopatológicas no pulmão de cães submetidos à pneumonectomia esquerda em abordagem comparativa entre dois tipos de sutura de coto brônquico (manual e mecânica). Foram utilizados doze cães, machos e fêmeas, adultos, sem raça definida, pesando entre quinze e vinte quilos sendo avaliados as alterações microscópicas apresentadas pelo pulmão direito e as alterações do eletrocardiograma. Todos os animais apresentaram-se em condições clínicas satisfatórias no período pós-operatório. As principais alterações eletrocardiográficas observadas no período pós-operatório foram desvio de eixo cardíaco, bloqueio sinoatrial e isquemia de miocárdio. No exame histopatológico, constatou-se atelectasia pulmonar, proliferação de epitélio de bronquíolo tendendo à obliteração, bronquiolite obliterante e enfisema pulmonar. O estudo sugere ainda que o pulmão direito foi submetido à hipertensão pulmonar.
