Abstract
BACKGROUND Cavernous sinus (CS) dural arteriovenous fistulas (DAVFs) are commonly treated by transvenous embolization, but the details of treatment need to be more clearly defined. We propose a classification of CS-DAVF that can contribute to formulating endovascular treatment process. METHODS CS-DAVF was classified into seven categories based on the cumulative CS range and drainage patterns. CS-DAVF angioarchitecture, clinical characteristics, treatment strategies, and outcomes of CS-DAVF patients treated in our hospital from 2012 to 2021 were summarized and analyzed. RESULTS Among the 116 patients with CS-DAVF: Type 1, 71 (61.2%); Type 2, 9 (7.8%); Type 3, 18 (15.5%); Type 4, 2 (1.7%); Type 5, 8 (6.9%); Type 6, 3 (2.6%); and Type 7, 5 (4.3%). Inter-CS or inferior petrosal sinus drainage was relatively rare in Types 1 and 6 (P < 0.001 and P < 0.001); basilar venous plexus drainage was more prevalent in Types 2, 5, and 7(P = 0.019). Inferior petrosal sinus occlusion was more commonly seen in Types 2, 3, and 5 (P = 0.005). The most frequent first symptoms and symptoms at admission in patients with CS-DAVF is ocular/orbital symptoms, occurring in 64 cases (55.2%) and 104 cases (89.7%), respectively. In this study, 108 patients (93.1%) underwent endovascular embolization. Among those who received endovascular embolization, 96 (88.9%) CS-DAVFs were treated via transvenous embolization. In long-term follow-up, 98 cases (84.5%) achieved cure, and 17 cases (14.7%) showed symptomatic improvement. CONCLUSION Our proposed classification system based on cumulative CS range and drainage patterns can assist in formulating treatment strategies for transvenous embolization.

Abstract
Accurate microcatheter placement for anterior condylar arteriovenous fistula (AVF) enables selective transvenous embolization (TVE) and helps to avoid hypoglossal nerve palsy. Anterior condylar AVF has a shunted pouch within the condylar vascular and osseous structures. Detailed anatomical comprehension of the shunted pouch is essential, in addition, we believe that it is important to have a strategy for where in the shunted pouch to start filling with coils. Specifically, we consider that it is important to structurally understand the more upstream location (arterial side) within the shunted pouch (called "shunted pouch entry zone"), guide the microcatheter there, and embolize from that site. Although several studies have discussed the usefulness of intraoperative cone-beam computed tomography (CBCT) for treating anterior condylar AVF, there are no studies which have mentioned the importance of microcatheter position before coil embolization in selective TVE as in this study. Intraoperative localization of the shunted pouch entry zone is often difficult. Herein, the authors report that cone-beam computed tomography (CBCT) can assist accurate microcatheter tip placement at the shunted pouch entry zone before staring embolization. This is the novel application of intraoperative CBCT to treat anterior condylar AVF successfully treated with precise and selective TVE.

Abstract
There are multiple treatment alternatives for cavernous dAVFs, with transvenous routes being most common. Among these routes, occluded inferior petrosal sinus is well-described, and, apart from being imaginative and elegant, it is also safe and effective. Herein we describe the application of this method to reach the fistulous pouch of a cavernous dAVF via an occluded superior petrosal sinus.

Abstract
The aim of this review is to describe the acquisition and reformatting of state of the art high resolution cone beam CT (HR-CBCT) and demonstrate its role in multiple neurovascular conditions as a tool to improve the understanding of disease and guide therapeutic decisions. First, we will review the basic principle of CBCT acquisition, followed by the injection protocols and the reformatting paradigms. Next, multiple applications in different pathological conditions such as aneurysms, arteriovenous malformations, dural arteriovenous fistulas, and stroke will be described. HR-CBCT angiography, widely available, is uniquely useful in certain clinical scenarios to improve the understanding of disease and guide therapeutic decisions. It rapidly is becoming an essential tool for the contemporary neurointerventionalist.AChoAho.

Abstract
A cavernous sinus dural arteriovenous fistula (CS-DAVF) is an abnormal arteriovenous communication involving the dura mater within or near the CS wall. The dural arteries from the internal carotid artery and external carotid artery supply the CS-DAVF, and the superior ophthalmic vein (SOV) and inferior petrous sinus (IPS) are frequent venous drainers. In CS-DAVF cases, high-risk lesions require treatment. Endovascular treatment (EVT) has been the first-line option for CS-DAVFs. To our knowledge, a review of the EVT of CS-DAVFs is lacking. Therefore, in this paper, we review the available literature on this issue. In addition, some illustrative cases are also provided to more concisely expound the EVT of CS-DAVFs. According to the recent literature, transvenous embolization via the IPS is considered the most effective method for EVT of CS-DAVFs. In addition, the transorbital approach is another reasonable choice. Other venous approaches can also be tried. Because of the low cure rate, transarterial embolization for CS-DAVFs is limited to only highly selected patients. In the EVT of CS-DAVFs, various agents have been used, including coil, Onyx, and n-butyl cyanoacrylate, with coil being the preferred one. In addition, when EVT cannot obliterate the CS-DAVF, stereotactic radiotherapy may be considered. In general, despite various complications, EVT is a feasible and effective method to manage CS-DAVFs by way of various access routes and can yield a good prognosis.
