And the coarctation of aorta were found in two calves at necropsy. 1. In the bovine fetuses and newborns, the arch of aorta was found to have the stenosis in the area between the origin of the common brachiocephalic trunk and the connection of ductus arteriosus, and it was recognized to be the isthmus aortae. However, it was not evident in the mature cattle. 2. In two calves with the coarctation of aorta, the isthmus aortae were hypoplastic and thin, while the ductus arteriosus were patent widely. 3. In addition of the coarctation of aorta, case one showed multiple defects such as ventricular septal defect, levoposition of pulmonary trunk, abnormal origins of left subclavian artery and coronary arteries and hypoplasia of left kidney. Case two had also other defects such as ventricular septal defect, dextraposition of aorta and hypoplasia of left ventricle. 4. The left subclavian artery originated abnormally from the coarctation of aorta, but had normal development.}, pages = {105--115}, title = {ウシにおける大動脈峡部の存在と子ウシの大動脈縮窄2例}, volume = {29}, year = {1982} }
