Abstract
OBJECTIVE AND IMPORTANCE
We report a rare case of a ruptured de novo aneurysm induced by ethyl 2-cyanoacrylate.
CLINICAL PRESENTATION
A 44-year-old woman had undergone microvascular decompression for a right-sided facial spasm. The preoperative vertebral angiogram did not show any aneurysmal dilation. The right anteroinferior cerebellar artery, which was compressing the exit zone of the facial nerve, was detached and fixed to the dura mater with ethyl 2-cyanoacrylate. Nine years later, the patient suffered a subarachnoid hemorrhage caused by the rupture of a newly developed aneurysm of the right anteroinferior cerebellar artery.
INTERVENTION
The aneurysm was clipped 2 days after onset of the subarachnoid hemorrhage. It consisted of two bulges in the arterial wall on the proximal side of the meatal loop. One bulge was stuck to the dura mater of the pyramis by ethyl 2-cyanoacrylate, which had been used in the microvascular decompression 9 years previously.
CONCLUSION
This is the first reported clinical case of a de novo aneurysm induced by a cyanoacrylate adhesive. Ethyl 2-cyanoacrylate can damage the arterial wall and induce a de novo aneurysm.
