Malformation of the thoracic aorta associated to aneurysms of the arch: an extraanatomic surgical approach.

Fig. 1. Angio-MR (a) and DSA of the thoracic aorta (b) show two aneurysms in a right-sided aortic arch. The right common carotid artery takes origin from the ascending aorta; the right subclavian artery and the left brachiocephalic trunk take origin from the descending aorta. A second DSA via interatrial transeptal injection of contrast shows a coarctation with a 100 mmHg gradient of pressure (c) (the arrow indicates the coarctation).
