“…Diana et al reported a case that iatrogenic DAVF developed on the same draining vein of a previously treated pial micro-arteriovenous malformation, which suggested that the unresected venous drainage of an AVM might be the substratum for neo-angiogenetic processes (17). A few cases of DAVF are caused by congenital factors, such as abnormal venous sinus development and genetic mutations (15,(18)(19)(20). External factors or their own factors lead to venous sinus hypertension, further causing cerebral tissue hypoperfusion and hemodynamic changes, both of which promote the expression of neovascular factors and cause abnormal neovascularization of arteries and veins, resulting in the formation of arteriovenous fistulas, which is the mainstream view of the pathogenesis of DAVF (15,21,22).…”

Kojima et al suggested that venous hypertension is associated with increased vascular endothelial growth factor (VEGF) expression, which may further induce DAVF proliferation (23).…”

IntroductionTo evaluate treatment strategies and clinical outcomes following endovascular embolization of tentorial dural arteriovenous fistulas.MethodsWe retrospectively analyzed 19 patients with tentorial dural arteriovenous fistulas admitted to the Department of Neurosurgery at Jiangsu Provincial People’s Hospital between October 2015 and May 2022, all treated with endovascular therapy. To collect and analyze patients’ clinical presentation, imaging data, postoperative complications, and prognosis and to analyze the safety and clinical outcomes of endovascular treatment of tentorial dural arteriovenous fistulas.ResultsImaging cure was achieved in 18 patients, with the arterial route chosen for embolization in 17 patients and the venous route in one patient; one patient received partial embolization. Staged embolization was performed in four patients. At postoperative follow-up of 9–83 months (37.8 ± 21.2), all 19 patients had recovered well (mRS score ≤ 2). Three patients experienced perioperative complications: intraoperative Onyx reflux into the middle cerebral artery in one patient; postoperative permanent limited left visual field loss and deafness in the left ear in one patient; and transient diplopia, vertigo, and decreased pain and temperature sensation of the left limb in one patient, with no abnormalities on post-procedure magnetic resonance examinations. A total of 17 patients completed a postoperative digital subtraction angiography review during follow-up, and one patient had a recurrence of an arteriovenous fistula.ConclusionEndovascular treatment of tentorial dural arteriovenous fistulas is safe and effective. Reduction of the Borden or Cognard classification via eliminating cortical venous reflux through multi-staged embolization or combined open surgery is a reasonable goal of treatment where complete obliteration of the fistula is not achievable.

“…Currently, most of them are considered acquired and potentially threatening. Some conditions are regarded as risk or enabling factors that may ultimately lead to the development of bDAVF (cranial surgeries, cranioencephalic trauma, hormonal alterations, sinusitis, meningiomas, endurance sports) 1,3 . Among all these factors, cerebral venous thrombosis (CVT) plays a paramount role, whether as a direct consequence of DAVFs or as a hemodynamic condition that may not only stagnate blood and open preexisting arteriovenous connections but also might stimulate neoangiogenesis and create de novo DAVFs 4 .…”

Background Brain dural arteriovenous fistulas(bDAVFs) are anomalous connections between dural arteries and cerebral veins or sinuses. Cerebral venous thrombosis(CVT) often precedes or coincides with bDAVFs and is considered a risk factor for these vascular malformations. Recently, vaccine-induced thrombotic thrombocytopenia causing CVTs has been associated with COVID-19 vaccines. Concurrently with the start of massive vaccination in our region, we have observed a fivefold increase in the average incidence of bDAVFs. Objective To raise awareness of the potential involvement of COVID-19 vaccines in the pathogenesis of bDAVF. Methods A retrospective review of demographic, clinical, radiological, COVID-19 infection and vaccination data of patients diagnosed with bDAVFs between 2011-2021 was conducted. Patients were divided into two cohorts according to their belonging to pre- or post-COVID-19 vaccination times. Cohorts were compared for bDAVFs incidences and demographic and clinical features. Results Twenty-one bDAVFs were diagnosed between 2011- 2021, 7 of which were diagnosed in 2021. The mean age was 57.7 years, and 62% were males. All cases except one were treated; of them, 85% were exclusively managed with surgery. All treated cases were successfully occluded. The incidence in 2021 was significantly higher than that in the prevaccination period (1.72 vs 0.35/100,000/year;p=0.036; 95%Confidence Interval=0.09-2.66). Cohorts were not different in age, sex, hemorrhagic presentation, dural sinus thrombosis or presence of prothrombotic or cardiovascular risk factors. Conclusion The significant increase in the incidence of bDAVF following general vaccination policies against COVID-19 observed in our region suggests a potential correlation between these two facts. Our findings need confirmation from larger cohorts and further pathogenic research.
