Set. 2006 7 4 397-399 JOURNAL OF Short Communication Veterinary Science Radiographic and computed tomographic evaluation of experimentally induced lung aspiration sites in dogs Kidong Eom Yunsang Seong Heemyung Park Nonghoon Choe Jongim Park Kwangho Jang department of Veterinary Diagnostic Imaging College of Veterinary Medicine Konkuk University Seoul 143-701 Korea department of Veterinary Surgery College of Veterinary Medicine Kyungpook National University Daegu 702-701 Korea This study was performed to radiographically examine the prevalence of aspiration sites and to evaluate their atomical correlation with the bronchial pattens. Ten healthy beagle dogs were repeatedly radiographed at weekly intervals in the left and right lateral ventrodorsal VD and dorsoventral DV positions. Three mililiters of iohexol distilled with same volume of saline was infused into the tracheal inlet. Which lung lobe was aspirated was decided upon by the presence of a significant alveolar pattern due to the contrast medium. Alveolar patterns were identified at the left 100 and right cranial lung lobes 77 with the dogs in dependant lateral recumbency at the right caudal lung lobe 71 with the dogs in VD recumbency and at the right middle lung lobe 59 with the dogs in DV recumbency respectively. The anatomical correlation was evaluated by performing computed tomography. The right principal bronchus 165.8 1.6 was more straightly bifurcated than was the left principal bronchus 142.7 1.8 p 0.01 . In VD position the right side lung had a greater opertunity to become aspirated. The ventrally positioned right middle lobar bronchial origin was more easily to be aspirated the other laterally positioned ones. We think that these anatomical characteristics can be one of the causes for aspiration pneumonia to occur more frequently in the right side lung.
