Q-DSA during type B chronic aortic dissection endovascular repair.

What is it about?

Angiographic assessment of type B chronic aortic dissection can be complicated in thoracic endovascular aortic repair (TEVAR) procedures due to a complex flow pattern. The challenge in identifying the true and false lumen and the precise deployment of the endograft in the true lumen are hotspots in endovascular treatment dissections.

Why is it important?

Q-DSA serves as a real-time application tool that may provide additional support in the angiographic evaluation of type B chronic aortic dissec- tion during TEVAR. Visualizing the complex aortic dissection architecture can be simplified, thereby increasing diagnostic confidence and accuracy.

These preliminary findings can be a stepping-stone for a future pro- spective multicenter study. A related quantitative analysis and comparison with pre-procedural imaging could also further address the value of this technique in a clinical setting. This is very useful in cases of non-uniformity of opinion between operators or for less experienced clinicians.
