Transvenous embolization (TVE) through the superior ophthalmic vein (SOV) is a useful approach for the treatment of cavernous sinus (CS) dural arteriovenous fistulae (DAVFs). This venous route is usually confirmed by angiography. Herein, we present a case of favorable embolization of the CS DAVF through the angiographically occlusive SOV. A 61-year-old man presented with progressive exophthalmos and hypertonia. The patient was diagnosed with a CS DAVF, and TVE was planned. The first approach through the inferior petrosal sinus was infeasible; therefore, we attempted to approach the fistula through the left facial vein. The microcatheter was easily advanced to the shunt point through the angiographically occlusive SOV. We performed coil embolization, and the CS DAVF was completely obstructed.

Introduction

Cavernous sinus (CS) dural arteriovenous fistula (DAVF) is a subtype of intracranial DAVF. CS DAVFs often cause clinical symptoms, especially in eye fields. In contrast, cases with aggressive symptoms are fewer in number.[[1]]

Transvenous embolization (TVE) is the standard treatment for CS DAVFs. The inferior petrosal sinus (IPS) is the most common route for approaching CS. The transvenous approach from a facial vein (FV) through a superior ophthalmic vein (SOV) is often reported as an alternate route,[[2]],[[3]] commonly confirmed by angiography. Herein, we report a rare case of successful TVE of a CS DAVF from a FV through the angiographically occlusive SOV.

Case Report

Informed consent was obtained from the patient for the publication of this case report and accompanying images.

A 61-year-old man with progressive left exophthalmos and ocular hypertension was admitted to our hospital. He had no history of medication or trauma. Computed tomography and magnetic resonance imaging (MRI) revealed left exophthalmos and dilatation of the ipsilateral SOV [[Figure 1]]a, [[Figure 1]]b, [[Figure 1]]c. Time-of-flight MRI showed a high-intensity signal in the left CS [[Figure 1]]d. Digital subtraction angiography (DSA) demonstrated an arteriovenous fistula on the left CS; it was fed by the meningeal branch originating from the CS segment of the left internal carotid artery [[Figure 2]]a, [[Figure 2]]b, [[Figure 2]]c. Its draining routes were the left superior and inferior ophthalmic veins connected to the left internal jugular vein through the ipsilateral and deep FVs [[Figure 2]]d, [[Figure 2]]e, [[Figure 2]]f. Bilateral IPSs were angiographically obstructed. The patient was diagnosed with CS DAVF (Barrow type D), and we tried to occlude the fistula by TVE. We considered approaching it from the ipsi- or contralateral IPS as the first route. If infeasible, we planned to approach it from the ipsilateral deep FV as a second route.

TVE was performed under intravenous anesthesia with dexmedetomidine. A 5-Fr ENVOY catheter was placed in the left common carotid artery, and a 6-Fr ENVOY catheter was placed in the left internal jugular vein. Initial left common carotid angiography showed a drainage different from that seen in diagnostic DSA. The left SOV and left deep FV, planned as the second route, could not be confirmed; hence, only the tortuous FV drainage route remained [[Figure 3]]. We tried to approach the left CS from the ipsi- or contralateral IPS, as scheduled, but could not reach the shunt point. Other visible approach routes could not be confirmed without the tortuous FV drainage; hence, we approached the left CS from the left FV route. Subsequently, the microguidewire was smoothly advanced in the angiographically occlusive angular vein (AV) and SOV, and it reached the shunt point [[Figure 4]]. We performed coil embolization, and the CS DAVF was completely occluded [[Figure 5]]. The patient's eye symptoms immediately improved. He was followed up for more than 1 year, with no recurrence.

Discussion

DAVF is a rare arteriovenous malformation disease with an unclear etiology. The elevation of venous pressure by venous occlusive changes is believed to cause a widening of physiological anastomosis between the dura maters.[[4]],[[5]] A few cases of DAVF are caused by trauma, infection, surgery, tumor, and venous thrombosis, but most cases are idiopathic.

The detection rate of DAVF is approximately 0.16–0.51 per 100,000 adults.[[6]],[[7]],[[8]] Previous studies from Western countries have reported that the most frequent location of DAVFs was the transverse-sigmoid sinus, followed by the CS.[[7]] In contrast, the CS was reported as the most frequent location of DAVFs in Asian populations.[[1]] Hence, the distribution of the shunt point may vary with regions.

Among patients with CS DAVF, aggressive symptoms were present in only 3% of the cases; however, almost all of them had clinical symptoms.[[1]] The common clinical symptoms were sixth cranial nerve palsy (77%), exophthalmos (65%), chemosis (59%), third cranial nerve palsy (59%), visual loss (41%), pulsatile tinnitus (41%), headaches (18%), and retro-orbital pain (18%).[[2]] DAVFs with retrograde leptomeningeal venous drainages or other annoying symptoms have been treated with a variety of procedures, including endovascular embolization, direct surgery, radiation surgery, or a combination of these. The treatments were primarily endovascular, with success rates of 62%–81% for transvenous approaches.[[9]],[[10]]

Every draining route connecting the CS is a probable approach route. The IPS is the most common venous route for approaching the CS and could be used even if it is occluded. In case the IPS approach is infeasible, other approach routes are considered. The FV is often reported as an alternate route for approaching the CS, and its effectiveness is well known.[[2]],[[3]] This route is commonly confirmed by angiography, and it usually reaches the CS through the AV and SOV.

In the present case, the approach from the IPS was infeasible. The deep FV, considered as the second route, was angiographically occluded in the intraoperative DSA. Only the tortuous FV drainage route remained. Severe tortuosity and a steep angle at the junction of the AV and SOV sometimes prevent the passage of a microcatheter from the FV. However, the microguidewire was smoothly advanced to the CS through the angiographically occlusive AV and SOV. The microcatheter was advanced to the CS across the microguidewire. We embolized the shunt point using coils.

The reasons the FV route showed that dynamic angiographic changes for a short period of time are not yet clear; however, venous thrombosis or a hemodynamic change was considered. The general condition and vital signs of the patient were similar to those of diagnostic DSA. An intrajugular catheter was placed, which sometimes stagnates venous drainage, but there was no venous congestion during the procedure. CS DAVFs have been reported to show angiographic changes attributable to progressive thrombosis.[[11]] The shortest interval of drainage change was 7 days in this series, which is shorter than that in previous reports.

The angiographic change possibly showed an early phase of thrombosis, which might be an important factor for successful treatment. TVE from the FV route is less invasive; therefore, it is worth trying before attempting to approach other invasive procedures.
