Oh, the Rare and Confusing World of Non-Cavernous Sinus Dural Arteriovenous Fistulas
Step right up, folks, to marvel at the exotic and elusive non-cavernous sinus (CS) dural arteriovenous fistulas (DAVFs) that have decided to set up camp in the sphenoid bone. These little rascals are so rare and love to play hide and seek in the middle cranial fossa, making them a real treat for doctors who thought they’d seen it all.
In our grand tour of the middle cranial fossa, we’ve gathered a whopping 26 patients who’ve had the pleasure of hosting these DAVFs. Some of them decided to throw a party in the lesser sphenoid wing, while others preferred the spacious accommodations of the greater sphenoid wing. And guess what? A thrilling 23.1% of these partygoers had their celebrations end with a bang, presenting with intracranial hemorrhage or subarachnoid hemorrhage.
But wait, there’s more! The most popular symptom among our guests was eye symptoms, because who doesn’t love a good eye problem? Now, onto the main event: treatment. A majority of our patients were treated with the latest fashion in DAVF care, trans-arterial embolization (TAE) using the fanciest liquid embolic agents. A couple of them went for the transvenous embolization (TVE) route, because variety is the spice of life, right?
For those who like a more hands-on approach, surgical disconnection of the drainage veins was the way to go, especially when TAE just didn’t cut it. And would you believe it? An astonishing 92.3% of our patients achieved anatomic cure. We even had follow-ups ranging from 3 to 27 months, with only one patient who just couldn’t get enough and had a recurrence.
So, what have we learned from this escapade? Most patients can bid farewell to their DAVFs with a little endovascular intervention. But for those who like to be different, there’s always surgical ligation to fall back on. And remember, kids, not all DAVFs are connected to the cavernous sinus, so don’t go looking for connections where there aren’t any!
In conclusion, if you’re one of the lucky few with a laterocavernous sinus DAVF, you might just need that extra bit of surgical flair to be cured. But hey, who doesn’t love a good challenge?
