Abstract:
Objective To study the feasibility of interventional pulmonary lobectomy by animal experiment. Methods Twelve healthy dogs were divided into three groups randomly,with 4 in each. Group A: the target bronchus and alveoli were filled with emulsion of lapiodal and alveolar cells damage liquors and then the target bronchus was occluded with Polymethylmethacrylate(PMMA). Group B: The target bronchus was only occluded with PMMA. Group C: Pulmonary lobe was resected surgically. Arterial blood gases were measured at the time of pre-procedure and post-procedure and then 1st, 2nd, 3rd and 4th week after the procedure respectively. Chest radiography histology and bacterial culture of tissue of target lung lobe were made after 4 weeks. Results There was a significant difference in arterial blood-gas among 3 groups pre-procedure in comparion with those of post-proceduce immediately (P0.05) in comparing with 1st, 2nd, 3rd and 4th week after the procedure. Atelectasis was shown radiologically with histological formation of fibrosis of target lung lobe but no bacteria grew in target tissue 4th week after the procedure. There were two cases of lung atelectasis but no pulmonary fibrosis occluded in group B. Conclusions Interventional pulmonary lobectomy might be obtained after the target bronchus and pulmonasy alveoli were filled with emulsion of dipiodal and alveolar cells damage liquors and then the target bronchus was occluded with PMMA.
