Successful Transarterial Guglielmi Detachable Coil Embolization of Post-Traumatic Fistula between a Posterior Communicating Artery Aneurysm and the Cavernous Sinus

Abstract

<jats:p> We describe a case of a post-traumatic posterior communicating artery (PCoA) aneurysmcavernous sinus fistula, which is an extremely rare complication of craniocerebral trauma, successfully treated with endosaccular coil embolization via transarterial route. Endosaccular embolization with Guglielmi detachable coils via transarterial route appears to be a feasible, effective and minimally invasive option for the treatment of post-traumatic fistula between the PCoA aneurysm with a small ostia and the cavernous sinus in the subacute phase. </jats:p>

A Rare Case of Posterior Communicating Artery Pseudoaneurysm Caused by Traumatic Head Injury

“…Endovascular treatment for the aneurysm and aneurysmal cavernous fistula was arranged. After the procedure, angiography demonstrated complete occlusion of the aneurysm and the fistula [5].…”

“…These pseudoaneurysms are accompanied with Carotid Cavernous Fistula (CCF). These cases are treated by transarterial coil embolization, surgical clipping of P-com aneurysm, neck of aneurysm or fistulous opening into the cavernous sinus of the aneurysm dome, trans-arterial balloon embolization of the CCF and trapping of the aneurysm [5][6][7][10][11][12]. Intervention for occlusion of the fistula and pseudoaneurysm are initiated at least one month after head injury.…”
