견(犬)에서의 개방성(開放性) 동맥관(動脈管) 증례(症例) = Patent Ductus Arteriosus in the Dog

다국어 초록 (Multilingual Abstract)

The ductus arteriosus (Botallo's duct) is a vascular communication between the pulmonary artery near its bifurcation and the aorta distal to the origin of the left subclavian artery. A surgical operation was tried in the shepherd dog which was affected by patent ductus arteriosus. The patient was six months old and weighed about 11kg. Pentobarbital sodium, 26 mg/kg was used intravascularly for the anesthesia. And then a respirator was used for the patient. The thoracotomy incision was made over the fourth intercostal space on the left and the ductus arteriosus was ligated twice. But the patient revealed ventricular fibrillation at three minutes after ligations of ductus arteriosus. So the cardiac massage was done after incision of pericardium and then the defibrillator was used for the defibrillation. But the patient was not recovered without effect. It was considered that if there is complication or cyanosis, the adaptability of surgical operation should be specially considered. Histologically, chronic passive congestion of liver was observed.
