Transvenous Aneurysm Sac and Rupture Point Coil Embolization of Direct Carotid Cavernous Fistula after Pipeline Embolization

چکیده
A delayed aneurysm rupture after flow diverter therapy is a rare but serious complication. Due to the anatomical specificity, a delayed rupture of a carotid cavernous aneurysm may cause a direct carotid cavernous fistula (dCCF). We present a novel therapeutic approach for treatment of dCCF after flow diverter therapy using the Pipeline embolization device (PED). An 86-year-old woman suffered from dCCF after PED embolization. A microcatheter was advanced through the transvenous approach into the cavernous sinus (CS) and further inserted into the aneurysm sac via the rupture point. Coil embolization of both the aneurysm sac and a small part of the CS adjacent to the fistulous site could achieve not only the immediate aneurysm occlusion but also the rupture point obliteration with a small amount of coil mass in the CS.

common internal carotid artery (ICA) -basilar artery anastomosis with an incidence between 0.1% and 0.3% (1). Anomalous cerebellar artery originating from the PTA has rarely been reported (2, 3). Rarely when an aneurysm is combined and ruptures into the cavernous sinus, spontaneous trigeminal-cavernous fistula can develop, which is usually treated by transarterial detachable balloon embolizatio...

We describe an iatrogenic perforation of a paraclinoid aneurysm during balloon-assisted coil embolization that resulted in simultaneous subarachnoid contrast extravasation and a carotid cavernous fistula. The causative factors specifically related to the balloon-assisted method that led to aneurysm rupture are discussed as well as strategies for dealing with this complication.

Stent assisted coiling (SAC) is a useful technique for the treatment of wide necked complex aneurysm. As the frequency of SAC increases, stent-related complications such as thromboembolism, aneurysm rupture, and vessel rupture have been reported. However, to the best of our knowledge, carotid-cavernous fistula (CCF) after SAC has never been reported. The authors experienced a case of direct CCF...

We report a case of a patient who developed a remote dural arteriovenous fistula involving the left sigmoid sinus 4 months after successful transarterial embolization of a carotid cavernous fistula. This rare occurrence has been reported after transvenous embolization, but this represents the first case, to our knowledge, after transarterial coil embolization. We present our findings along with...
