In the vast majority of patients (90%), the head pain of carotid dissection resolves within 1 week (4,47). In verte- bral dissection, the headache may last up to 5 weeks (47). In rare cases, however, the headache may last for years after the dissection, particularly in patients who develop pseudoaneurysms (36,37,47).

Death is typically secondary to extensive intracranial dissection, brainstem infarction, or subarachnoid hemorrhage.
What is a communicating aneurysm?
Anterior Communicating Artery Aneurysms. ACoA aneurysms arise within the complex of the two anterior cerebral arteries at their anastomosis via the ACoA. They are ensconced by the anterior cerebral arteries and branches leading to a complex and highly variable dissection (Fig. 67-19).
