Abstract

OBJECTIVE:

To identify petrous internal carotid bleeding aneurysm as a complication of gasserian ganglion thermocoagulation.

PATIENTS:

A single case presenting with epistaxis and otorrhagia 1 month after gasserian ganglion thermocoagulation in the treatment of refractory trigeminal neuralgia.

INTERVENTION(S):

Gasserian ganglion thermocoagulation, computed tomographic scan, and angiocomputed tomographic scan revealing petrous internal carotid ruptured aneurysm and internal carotid embolization.

MAIN OUTCOME MEASURE(S):

Radiologic diagnosis of the vascular injury after gasserian ganglion thermocoagulation.

RESULTS:

Radiologic identification of ruptured internal carotid artery as the cause of simultaneous epistaxis and otorrhagia.

CONCLUSION:

Gasserian ganglion thermocoagulation may cause aneurysm and rupture of the petrous portion of the internal carotid artery.
