Arch of aorta (AOA) is the continuation of ascending aorta, and usually, it gives three branches, namely, from right to left, brachiocephalic trunk, left common carotid artery (LCCA), and left subclavian artery (LSCA).
We are reporting a unique case of saccular pseudoaneurysm of the mediastinal segment of the left common carotid artery in a patient with delayed presentation (10 years after trauma), and a penetrating and persistent foreign body in thorax as a predisposing factor.
For (RICA) Right Internal Carotid Artery, (LCCA) Left Common Carotid Artery and (LICA) Left Internal Carotid Artery, there was a significantly higher thickness among patients with hypertension as compared to the control group with p=0.
This pivotal study follows both an early feasibility study conducted in Zones 0-1 with the branch device in the brachiocephalic or left common carotid arteries and a feasibility study in Zone 2 with the branch device in the left subclavian artery.
However, the palpable mass was noted to be the right common carotid artery originating from the left common carotid artery at the base of the neck crossing the midline just below the thyroid isthmus [Figure 2].
