Endovascular embolization of traumatic intracavernous pseudoaneurysm of internal carotid artery.

Delayed epistaxis after head trauma is a common presentation of’ pseudoaneruysm, which should be investigated. Traumatic pseudoaneurysm of the intracavernous ICA is a rate condition resulting from fracture base of the skull. gunshot injuries to head or after surgery on pituitary fossa or sphenoid sinus. The pseudoaneutysni arises at the i nfrac I inoid port ion proximal to opthalmic artery and may reach such dimensions as to occupy the sphenoid and ethmoid sinuses. Pulsating pseudoaneutysi’n with tear of dural coverings may rupture into the sphenoid sinus or nasal cavity and cause massive epistaxis. It can he fatal in 50% of the cascs if left untreated. Latent period may be few days to many years. Definitive diagnosis is by angiography and treatment is either surgical or endovascular.
