To review the main aortic repair techniques.
To define the normal postoperative appearance of thoracic and abdominal aorta.
To help avoid imaging pitfalls.
To review the most common complications.
Aortic interventions can be divided mainly in three categories:
open repair surgery
Open repair surgery
Open repair surgery involves replacement of the aorta with a graft usually composed of synthetic polyester.Graft can be placed either through an interposition graft or an inclusion graft (Fig. 1 Fig. 2).
The most common use of open repair surgery is for treatment of ascending aortic diseases, as this segment is not usually suited for endovascular treatment.
Open repair surgery of the ascending aorta usually includes:...
Findings and procedure details
CTA protocol usually involves three phases:
unenhanced phase, contrast enhanced arterial and delayed phases.
Unenhanced images are very helpful in avoiding imaging pitfalls.
Contrast enhanced arterial phase are essential in the assessment of vascular anatomy.
Contrast enhanced delayed phase (180 s) may be crucial for detection of slow flow endoleaks.
ECG gating is mandatory in the evaluation of aortic root and coronary artery ostia.
Contrast material should be administrated at a high flow rate (4-5 ml/sec).
Aortic grafts have no distinctive imaging features. They usually...
Knowledge of CTA appearance of open, hybrid, endovascular procedures is essential to the proper evaluation and interpretation of post-operative aorta.
