Objective:
To study the application of multi-slice spiral CT angiography (MSCTA) after endoluminal exclusion of aortic diseases.
Methods:
16-slice CT angiography was performed in 15 patients with aortic dissection and 4 patients with aortic aneurysm after endovascular exclusion. Two observers analysed the images and interpreted the outcomes and complications after endovascular exclusions of aortic dissection and aortic aneurysm.
Results:
In 19 patients, thrombus was found in all the false lumens of aortic dissection and the outer-stent cavity of aortic aneurysm. However, one patient with aortic aneurysm graft thrombosis; 4 patients had endo-leak (3 with type I endo-leak, 1 with type III endo-leak complicating graft deformation); one achieved perfusion recovery, and one experienced thrombolysis of superior mesenteric artery.
Conclusion:
MSCTA can be an objective tool for the post-operative evaluation of endovascular exclusion of aortic diseases.
