Introduction:
We present a patient with an acutely ruptured, wide-necked aneurysm of the left posterior cerebral artery (PCA) treated with Guglielmi detachable coils using the remodeling technique.
Methods:
Since the left vertebral artery was compressed due to a tumor in the cerebellopontine angle and the right vertebral artery was hypoplastic, we used a carotid artery approach via a persistent primitive trigeminal artery (PPTA) to selectively catheterize the aneurysm.
Results:
The aneurysm was occluded completely.
Conclusion:
To our knowledge this is the first case of a wide-necked PCA aneurysm treated via a PPTA and using the remodeling technique. In patients with hypoplastic vertebral arteries and a PPTA, this approach may represent an alternative for selective embolization of posterior circulation aneurysms not amenable to the conventional approach.
