Onyx embolization of dural arteriovenous fistulas of the cavernous sinus through the superior pharyngeal branch of the ascending pharyngeal artery

Object The purpose of this study was to assess the efficacy of Gamma Knife surgery (GKS) for treating cavernous sinus dural arteriovenous fistulas (CSDAVFs). Methods Of the 4123 GKSs performed between May 1992 and March 2009, 890 procedures were undertaken to treat vascular lesions. In 24 cases, the vascular lesion that was treated was a dural arteriovenous fistula, and in 6 of these cases, the lesion involved the cavernous sinus. One of these 6 cases was lost to follow-up, leaving the other 5 cases (4 women and 1 man) to comprise the subjects of this study. All 5 patients had more than 1 ocular symptom, such as ptosis, chemosis, proptosis, and extraocular movement palsy. In all patients, CSDAVF was confirmed by conventional angiography. Three patients were treated by GKS alone and 2 patients were treated by GKS combined with transarterial embolization. The median follow-up period after GKS in these 5 cases was 30 months (range 9–59 months). Results All patients experienced clinical improvement, and their improvement in ocular symptoms was noticed at a mean of 17.6 weeks after GKS (range 4–24 weeks). Two patients received embolization prior to GKS but did not display improvement in ocular symptoms. An average of 20 weeks (range 12–24 weeks) was needed for complete improvement in clinical symptoms. There were no treatment-related complications during the follow-up period. Conclusions Gamma Knife surgery should be considered as a primary, combined, or additional treatment option for CSDAVF in selected cases, such as when the lesion is a low-flow shunt without cortical venous drainage. For those selected cases, GKS alone may suffice as the primary treatment method when combined with close monitoring of ocular symptoms and intraocular pressure.

The Right

Angiographic changes of the sylvian veins, superior ophthalmic vein (SOV), and superior petrosal sinus (SPS) before and after endovascular treatment were determined for 18 patients with dural arteriovenous fistulas (AVFs) involving the cavernous sinus, and pitfalls of endovascular treatment, especially regarding venous drainage routes, for 3 of the patients were reported. Case 1: 57-year-old woman who presented with right abducens nerve palsy had a Barrow type D fistula in the right cavernous sinus draining into the bilateral inferior petrosal sinuses (IPS). One of the ipsilateral sylvian veins that had drained antegradely before treatment was occluded, and a small lacunar infarction in the corona radiata developed after transvenous embolization (TVE) of the right cavernous sinus. Case 2: 72-year-old woman who presented with symptoms of right ocular hypertension had a type D fistula in the right cavernous sinus draining into only the ipsilateral SOV. Conjunctival hyperemia persisted and was aggravated after angioanatomical obliteration of the fistula by transarterial embolization. Case 3: 55-year-old man who presented with left abducens nerve palsy had a type D fistula in the left cavernous sinus draining into the ipsilateral IPS and sylvian vein. The dural AVF was obliterated once with TVE, but recurred 1 week later with retrograde drainage into the ipsilateral SPS and mesencephalic veins. A second TVE resulted in complete obliteration of the fistula. In conclusion, detailed analysis of drainage routes is necessary for planning of treatment of patients with dural AVF, and prompt treatment is needed when redistribution of drainage routes develops during or after TVE.

Type 3

Dural arteriovenous fistulas (DAVFs) of the hypoglossal canal (HCDAVFs) are rare and display a complex angiographic anatomy. Hitherto, they have been referred to as various entities (for example, “marginal sinus DAVFs”) solely described in case reports or small series. In this in-depth review of HCDAVF, the authors describe clinical and imaging findings, as well as treatment strategies and subsequent outcomes, based on a systematic literature review supplemented by their own cases (120 cases total). Further, the involved craniocervical venous anatomy with variable venous anastomoses is summarized. Hypoglossal canal DAVFs consist of a fistulous pouch involving the anterior condylar confluence and/or anterior condylar vein with a variable intraosseous component. Three major types of venous drainage are associated with distinct clinical patterns: Type 1, with anterograde drainage (62.5%), mostly presents with pulsatile tinnitus; Type 2, with retrograde drainage to the cavernous sinus and/or orbital veins (23.3%), is associated with ocular symptoms and may mimic cavernous sinus DAVF; and Type 3, with cortical and/or perimedullary drainage (14.2%), presents with either hemorrhage or cervical myelopathy. For Types 1 and 2 HCDAVF, transvenous embolization demonstrates high safety and efficacy (2.9% morbidity, 92.7% total occlusion). Understanding the complex venous anatomy is crucial for planning alternative approaches if standard transjugular access is impossible. Transarterial embolization or surgical disconnection (morbidity 13.3%–16.7%) should be reserved for Type 3 HCDAVFs or lesions with poor venous access. A conservative strategy could be appropriate in Type 1 HCDAVF for which spontaneous regression (5.8%) may be observed.
