[Dextraposition of the aortic arch combined with atresia of the left brachiocephalic truncus, a contribution to the varieties of the aortic arch (author's transl)].

We report on a case of a 62-years old woman with dextroposition of the aortic arch and an atresia of the left brachiocephalic truncus. In opposite to the varieties of the supraaortic vessels, which are in most cases occasionally seen, this patient suffered from cerebrovascular insufficiency and subclavian-steal-syndrome. We suppose, that this late manifestation of a variety of the aortic arch with an atresia of a great supraaortic vessel is caused by the brain's physiosclerosis. The correction was made by a 8 mm dacron prosthesis from the ascending aorta to the left subclavian-carotid junction.
