A: MR angiography of native coarctation of the aorta in a 9 year old boy with subtotal stenosis at the level of the aortic isthmus (*) and multiple subclavian and intercostal collaterals (+) inserting into the descending aorta (DAO) distal to stenosis (AO= aorta).
B: Virtual reality (VR) 3D reconstruction from MR angiograpy in a 6 year old girl with aortic coarctation (*) and collaterals (+).
C: VR 3D reconstruction from MR angiography after surgical resection of aortic coarctation and end-to-end anastomosis. Only very slight residual narrowing at the site of the former stenosis (*).
D: VR 3D reconstruction form MR angiography of re-stenosis (*) after surgical resection of aortic coarction and end-to-end-anastomosis. AAO = ascending aorta, DAO= descending aorta.
