Access to cavernous dAVF via occluded superior petrosal Sinus

Area of Science:

• Neurosurgery
• Interventional Neuroradiology
• Vascular Neurology

Background:

• Cavernous dural arteriovenous fistulas (dAVFs) are complex vascular malformations requiring effective treatment.
• Transvenous routes are the most common endovascular approach for treating cavernous dAVFs.
• Occlusion of the inferior petrosal sinus is a known, safe, and effective transvenous route.

Purpose of the Study:

• To describe a novel application of the occluded sinus technique for treating cavernous dAVFs.
• To demonstrate the feasibility of accessing the fistulous pouch via an occluded superior petrosal sinus.

Main Methods:

• Application of the occluded sinus technique for endovascular treatment of a cavernous dAVF.
• Utilizing an occluded superior petrosal sinus as the venous access route.
• Embolization of the fistulous pouch via the described transvenous route.

Main Results:

• Successful navigation to the fistulous pouch of a cavernous dAVF through an occluded superior petrosal sinus.
• Demonstration of the safety and effectiveness of this alternative transvenous approach.
• Achieved obliteration of the dAVF using this method.

Conclusions:

• Accessing a cavernous dAVF via an occluded superior petrosal sinus is a safe and effective alternative transvenous treatment.
• This technique offers an imaginative and elegant solution for challenging cases.
• The described method expands the endovascular treatment options for cavernous dAVFs.
