Anterior Communicating Artery Aneurysm Clipped Via an Endoscopic Endonasal Approach

Neurosurgery 68[ONS Suppl 2]:ons310–ons316, 2011 DOI: 10.1227/NEU.0b013e3182117063

The anterior communicating artery (AcoA) aneurysm is one of the most challenging aneurysms. As endovascular techniques evolve, a remaining challenge is the reduction of complications related to the surgical approach. Although the endonasal approach is widely used for pituitary adenomas and is increasingly popular for suprasellar tumors, only 2 aneurysm cases have been reported.

OBJECTIVE: To the best of our knowledge, we are reporting the first case of successful endoscopic endonasal clipping of an unruptured ACoA aneurysm.

METHODS: An ACoA aneurysm was discovered in a 55-year-old man before he was to undergo an endoscopic biopsy of an orbital lesion. Because of the operative corridor formed during this first operation and ideal conformation of the aneurysm for this line of sight, we formulated an endoscopic route for this ACoA aneurysm.

RESULTS: An endoscopic endonasal transplanum-transtuberculum approach was performed. Proximal and distal control was obtained, and the AcoA aneurysm was successfully clipped. The postoperative course was uneventful with a rapid recovery.

CONCLUSION: On the road of innovation in the treatment of intracranial aneurysms, the endoscopic approach provided another option whose value must be weighed in terms not only of feasibility but in the patient’s best interest. We caution extreme prudence if considering this procedure as an alternative to well-established techniques. Yet its upward route offers limited retraction for deep-seated lesions. Rapid progress of endoscopic techniques may prove promising for well-selected cases of ACoA aneurysms.
