Atypical Aortic Coarctation with Stenosis of Aortic Arch or its Branches

　Three cases of atypical coarctation with　the stenosis of aortic arch or its branches　were described, one of which, as the result　of operation, was revealed to be of con-genital origin as far as the abdominal aorta　and renal arteries were concerned．

　The relationship between the two condi-tions, which apparently seem to be inde-pendent, were studied on reference of　literatures．　When the atypical coarctation　of aorta and stenosis of aortic arch or its　branches coexist, they may be ascribed to　one common cause, namely, either non-specific arteritis　（pulseless disease）　or con-genital vascular anomaly．
