Coil Embolization For Sixth Cranial Nerve Palsy Caused By Persistent Primitive Trigeminal Artery
نویسنده
چکیده
The author reports on the case of a 60-year-old woman who presented with recurrent left sixth cranial nerve palsy. The patient was initially hospitalized to rule out an aneurysm of the internal carotid artery. Angiography revealed segmental dilation of the internal carotid artery and a persistent primitive trigeminal artery (PPTA) that coursed through the dorsolateral cavernous sinus, opening into the left anterior inferior cerebellar artery. Superselective visualization of the angioarchitecture allowed us to successfully occlude the cavernous segment of the PPTA by coil embolization. The palsy resolved and the patient remained asymptomatic for 24 months. The data on the role that PPTAs play in compression syndromes in the cavernous sinus is inconclusive. The author concludes that the pathogenesis of the sixth nerve pulsy can be caused in the existence of PPTA.

Coil embolization of a trigeminal-cavernous fistula.
A 53-year-old woman spontaneously incurred a right trigeminal artery-cavernous sinus fistula, manifested by an intracranial bruit and right sixth nerve palsy. This lesion was successfully managed by coil embolization via the transvenous and transarterial routes.
متن کاملTreatment of traumatic trigeminal-cavernous fistula by coil embolization and compression of carotid artery.
We report a case of a traumatic cavernous fistula supplied by a persistent primitive trigeminal artery. The process of treatment was unique in this case. Fistula was subcompletely occluded by coiling from primitive trigeminal artery. Residual fistula was helped to form thrombosis by compression of the carotid artery with hand in the procedure. Long-term follow-up was satisfactory. Traumatic cav...
متن کاملResolution of trigeminal neuralgia by coil embolization of a persistent primitive trigeminal artery aneurysm.
The persistent primitive trigeminal artery (PTA) is a rare anastomosis between the carotid artery and basilar artery. While most PTAs are asymptomatic, lateral variants can occasionally compress the trigeminal nerve and precipitate trigeminal neuralgia. Aneurysms of the PTA are exceptionally rare in the literature and have not previously been associated with trigeminal neuralgia. We present the...

embryological vascular remnants (1). The most common embryonic communication between the carotid and vertebrobasilar systems is a persistent trigeminal artery (PTA). This has been observed in 0.1 -0.2 % of cerebral angiograms, usually as an incidental finding (2). Although the presence of PTA is generally thought to be of uncertain significant, these arteries and their variants have been identi...
متن کاملCoil embolization of an aneurysm located at the trunk of the persistent primitive trigeminal artery.
A 71-year-old woman presented with an aneurysm at the trunk of the persistent primitive trigeminal artery (PPTA) manifesting as subarachnoid hemorrhage. Angiography and three-dimensional computed tomography revealed a wide-necked saccular aneurysm at the trunk of the left PPTA. Coil embolization with the balloon-assist technique was successful and PPTA patency was preserved. Preoperative conven...
