[Flow diverter treatment for dissecting aneurysm causing cavernous sinus syndrome].

Area of Science:

• Neurology
• Vascular Surgery
• Radiology

Background:

• Cavernous sinus syndrome presents with ophthalmoplegia, autonomic dysfunction, and trigeminal nerve sensory loss.
• Head trauma can precipitate cavernous sinus syndrome, necessitating consideration of dissecting aneurysms.
• Intracranial aneurysms causing compression require treatment, even if previously asymptomatic.

Purpose of the Study:

• To report a case of cavernous sinus syndrome secondary to a dissecting internal carotid artery aneurysm.
• To highlight the efficacy of flow diverter treatment for this specific condition.
• To emphasize the importance of early intervention.

Main Methods:

• A case report of a 23-year-old female with post-traumatic cavernous sinus syndrome.
• Diagnostic angiography to identify a dissecting aneurysm of the internal carotid artery.
• Treatment with a flow diverter device.

Main Results:

• Angiography confirmed a dissecting aneurysm at the right internal carotid artery's cavernous sinus segment.
• The patient underwent successful, uncomplicated flow diverter placement on day 6 post-injury.
• Rapid and complete radiological and clinical resolution of symptoms was observed.

Conclusions:

• Flow diverter treatment is safe and effective for dissecting aneurysms in the cavernous sinus segment of the internal carotid artery.
• Early treatment of such aneurysms can lead to complete resolution of cavernous sinus syndrome symptoms.
• Prompt intervention can rapidly cure ipsilateral ophthalmoplegia and facial sensory loss.
