Iatrogenic aortic dissection during right transradial intervention in a patient with aberrant right subclavian artery: A case report

Figure 1 Aortography and computed tomography of aorta and aberrant right subclavian artery. A: The guidewire reached the ascending aorta after forming a large loop in the left anterior oblique 30° view of coronary angiography. We were unable to advance the guiding catheter past the ostium of the right subclavian artery (white arrowhead); B: The aortogram using a 5Fr pigtail catheter via the right femoral artery shows a dissection flap of the right subclavian artery in the AP view (black arrowheads); C and D: The right subclavian artery did not originate from the right innominate artery (white dotted lines and red arrow heads in C and D). Instead, aberrant right subclavian artery emerged from the descending aorta. ARSA: Aberrant right subclavian artery; SCA: Subclavian artery; CCA: Common carotid artery.
