With the advent of high-resolution imaging and advancements in computational fluid dynamics(CFD)and computational structural mechanics(CSM)analyses, clinical simulation of endovascular intervention has gradually become feasible. Virtual stents have become indispensable for coil embolization. For braided stents, such as those with low-profile visualized intraluminal support and flow diverters, predicting postplacement elongation and contraction is challenging; however, software development has enabled more precise treatment planning...

We present a unique clinical case of venous congestive encephalopathy in the context of a cerebral arteriovenous fistula with clinical worsening secondary to valvular overdrainage. ICP monitoring, the different pressure settings of the programable CSF shunt and the detailed clinical description that is carried out offer us enough data to understand that this case provides important pathophysiological knowledge to a little-known disease.

Dural arteriovenous fistulas (DAVFs) are intracranial vascular lesions with abnormal communication between the dural arteries and dural and/or cortical venous systems. While benign DAVFs, like Cognard I and IIa/Borden I, can be observed, higher-grade DAVFs, such as Cognard IIb-V/Borden II and III, should be treated.1,2 This video article depicts the microsurgical management after embolization of a middle cranial fossa Cognard IV DAVF with venous varices causing mass effect in the right thalamus, basal ganglia, and posterior limb of the right internal capsule...

OBJECTIVE: Intracranial dural arteriovenous fistulas (dAVFs) are rare vascular lesions that can be asymptomatic or can lead to devastating hemorrhage based on the dAVF's aggressiveness. Several approaches can be taken to treat dAVFs, such as endovascular embolization and surgical ligation. However, very few studies have evaluated the influence of surgery compared to endovascular approaches on patient outcomes. This study was performed to analyze the clinical characteristics and outcomes of patients who underwent treatment for intracranial dAVF in which either endovascular embolization or microsurgical ligation was used...

OBJECTIVE: In contrast to high-grade dural arteriovenous fistula (dAVF), low-grade dAVF is mainly associated with tinnitus and carries a low risk of morbidity and mortality. It remains unclear whether the benefits of active interventions outweigh the associated risk of complications in low-grade dAVF. METHODS: The authors conducted a retrospective single-center study that included all consecutive patients diagnosed with an intracranial low-grade dAVF (Cognard type I and IIa) during 2012-2022 with DSA...

OBJECTIVE: The pathogenesis of intracranial dural arteriovenous fistulas (icDAVFs) is controversial. Cerebral vein thrombosis (CVT) and venous hypertension are recognized predisposing factors. This study aimed to evaluate the incidence of association between icDAVF and CVT and describe baseline aggressiveness and clinical outcomes for icDAVFs associated with CVT. The authors also performed a literature review of studies reporting icDAVF associated with CVT. METHODS: Two hundred sixty-three consecutive patients in two university hospitals with confirmed icDAVFs were included...

OBJECTIVE: Stereotactic radiosurgery (SRS) has been established as a safe and alternative treatment for dural arteriovenous fistulas (dAVFs). While embolization alone is the most commonly used modality for the treatment of dAVFs, the adjunctive use of embolization with SRS, with the growing use of SRS, has gained increasing interest in the past few years. However, the relative efficacy and safety of SRS combined with embolization versus SRS alone for dAVFs remains uncertain. Hence, this systematic review aimed to evaluate the efficacy of SRS with adjunctive embolization for intracranial dAVFs...

OBJECTIVE: Dural arteriovenous fistulas (dAVFs) of the superior sagittal sinus (SSS) are uncommon and represent 5%-12% of all intracranial dAVFs. SSS dAVFs can be divided into two main subtypes. The first type involves direct arterialization of the SSS, whereas the second type consists of a parasagittal arteriovenous shunt draining into a cortical vein directly lateral to the SSS and has retrograde cortical venous drainage with only secondary involvement of the SSS. Descriptions of the latter type of SSS dAVF are limited...

Central nervous system (CNS) dural arteriovenous fistulas (DAVF) have been reported in PTEN-related hamartoma tumor syndrome (PHTS). However, PHTS-associated DAVF remain an underexplored field of the PHTS clinical landscape. Here, we studied cases with a PTEN pathogenic variant identified between 2007 and 2020 in our laboratory (n = 58), and for whom brain imaging was available. Two patients had DAVF (2/58, 3.4%), both presenting at advanced stages: a 34-year-old man with a left lateral sinus DAVF at immediate risk of hemorrhage, and a 21-year-old woman with acute intracranial hypertension due to a torcular DAVF...

Arterial spin labeling (ASL) and three-dimensional (3D) time-of-flight (TOF) magnetic resonance angiography (MRA) are sensitive tools to detect dural arteriovenous fistula (DAVF), but hyperintensity in these images is also caused by jugular venous reflux. We present a case of a patient with renal failure on hemodialysis with retrograde flow into the internal jugular vein (IJV) mimicking DAVF. A 74-year-old man with a radial arteriovenous fistula for hemodialysis experienced transient dizziness. The TOF MRA and ASL revealed high signal intensity, suggesting the presence of a DAVF in the left transverse and sigmoid sinuses and the IJV...

BACKGROUND: Intracranial dural arteriovenous fistulas (dAVFs) are abnormal connections between arteries and veins within the dura mater. Various treatment modalities, such as surgical ligation, endovascular intervention, and radiosurgery, aim to close the fistulous connection. Although transvenous embolization (TVE) is the preferred method for carotid-cavernous fistulas, its description and outcomes for noncavernous dAVFs vary. This has prompted a systematic review and meta-analysis to comprehensively assess the effectiveness of TVE in treating noncavernous dAVFs, addressing variations in outcomes and techniques...

Carotid jugular arteriovenous fistulas are a documented complication of cannulation of the internal jugular vein. They may present with neck pain, headache, and cardiovascular aberrations. However, carotid jugular fistula secondary thrombus formation after jugular cannulation with radiographic presentation similar to dural arteriovenous fistula has not yet been reported in the literature. Below, we report the case of a 68-year-old male with an incidentally found carotid-jugular fistula secondary to pacemaker placement who had intracranial reflux on imaging, which was ultimately treated successfully through an endovascular approach...

OBJECTIVE: Intracranial dural arteriovenous fistulae (DAVF) represent a subset of cerebral vascular malformations associated with significant morbidity and mortality. In Japan, DAVF exhibits sex-based differences in anatomical distribution, with female predominance in the cavernous sinus (CS) and male predominance in the transverse sinus (TS). Nevertheless, the pathophysiology of DAVF is not fully understood, and hormonal influences are hypothesized to play a role in its development. This study aimed to investigate changes in the concentrations of sex steroid hormones between intracranial and peripheral sampling sites in CS- and TS-DAVF patients...
