Internal carotid false aneurysm after thermocoagulation of the gasserian ganglion.
Objective: To identify petrous internal carotid bleeding aneurysm as a complication of gasserian ganglion thermocoagulation.
Methods: A single case presenting with epistaxis and otorrhagia 1 month after gasserian ganglion thermocoagulation in the treatment of refractory trigeminal neuralgia. Methods: Gasserian ganglion thermocoagulation, computed tomographic scan, and angiocomputed tomographic scan revealing petrous internal carotid ruptured aneurysm and internal carotid embolization. Methods: 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.
Conclusions: Gasserian ganglion thermocoagulation may cause aneurysm and rupture of the petrous portion of the internal carotid artery.
