Arterial dissection into common carotid artery

Case contributed by: Dr Frank Gaillard

From the case: Arterial dissection into common carotid artery

Modality: CT

Case Discussion:

Again the ectatic and aneurysmal arch of aorta is demonstrated, with dissection flap originating in the right brachiocephalic artery and continuing into the common carotid artery on the right. This finishes prior to the CCA bifurcation, and appears unchanged when compared to the previous imaging. The internal carotid artery remains of even calibre, although markedly tortuous.

The left internal carotid artery and common carotid artery appear unremarkable.
