MR-angiography showing a large aneurysm of the ascending aorta (AaoA), a hypoplastic aortic arch and a recurrent stenosis following previous coarctation repair (white arrow) and enlarged intercostal arteries as sign of collateralization. In addition, there was a large pseudoaneurysm at the site of a Dacron patch used for initial coarctation repair (red arrow).

The proximal descending aorta was highly narrowed (Figure 10).

The ascending aortic aneurysm was resected and the aorta replaced with a prosthetic vascular graft and finally, an ascending-descending bypass was performed to restore continuity between the ascending with the distal descending aorta (Figure 11).

Left (2 pictures): CT-angiogram of a young patient with Takayasu aortitis with multiple stenoses in the thoracic and abdominal aorta and occlusion of the iliac arteries scheduled for an descending to bi-iliac extra-anatomic bypass. Right (2 pictures): CT-angiogram of a 45 yr-old female with severe calcific narrowing of the descending aorta as a result of a Takayasu more than 25 years before. Endovascular procedure was thought to be not ideal in this case.

CT-scan with angiography showed several narrowing at the level of the descending thoracic but also of the abdominal aorta (Figure 13 both left). She presented with a localized severe calcific stenosis of the descending aorta with a resting lumen of 3-4 mm at the narrowest site (Figure 13 both right).
Postoperative 3-D reconstruction of the CT-angio following ascending to infrarenal bypass in the patient with very calcified and narrowed descending aorta following Takayasu disease.

CT-scan demonstrated the correct position of the extra-anatomic graft (Figure 14).
