소아에서의 우측 쇄골하동맥 기시이상 -수술치험 2례- = Aberrant Right Subclavian Artery in Children -Report of Cases-

다국어 초록 (Multilingual Abstract)

Aberrant right subclavian arteries were experienced in two young children. This is a rare aortic arch anomaly that usually does not produce symptoms. Symtomatic patients require surgical interventions.We describe two young children who had aberrant right subclavian artery with symptoms of difficulty in swallowing and respiratory problems. Diagnosis was made by esophagography, aortography and 3-Dimension chest CT. Operation had been advocated through right thoracotomy without difficulty for ligation, division and anastomosis to the ascending aorta. Dysphagia lusoria was immediately relieved and postoperative course was uneventful. We consider that the right thoracotomy is the choice of operative approach and noninvasive diagnosis by 3-Dimension chest CT is easily made for infant with aberrant right subclavian artery.
