Pseudoaneurysm of the internal carotid artery with subsequent stent placement

An internal carotid angiogram (A) shows a focal dissection (arrow) in the cervical portion of the carotid artery. An angiogram performed two years later (B) shows a pseudoaneurysm at the previous site of dissection (arrow). Image C shows stent placement (arrowheads) across the mouth of the pseudoaneurysm. Six months later (D), an angiogram shows resolution of the pseudoaneurysm (arrowhead).
