Abstract Endovascular therapy is the primary treatment for the majority of tentorial dural arteriovenous fistulas (dAVF). Surgical occlusion is an effective alternative when embolization is not possible. This video demonstrates microsugical occlusion of a right-sided tentorial dAVF in a symptomatic 45-yr-old male. The dAVF was fed directly by meningohypophyseal trunk. Venous drainage was retrograde through the sphenoparietal sinus, superficial sylvian vein, vein of Labee, and transverse sinus. The patient underwent a right-sided pterional craniotomy; the sylvian fissure was widely opened. Subarachoid dissection was performed until a large arterialized draining vein was identified exiting dura subtemporally. Intraoperative indocyanine green angiography confirmed the fistulous site and the draining vein was occluded and divided. The patient remained neurologically intact after surgery. Immediate angiography demonstrates complete occlusion of the dAVF. This video demonstrates the surgical access obtained through a transylvian approach for this tentorial dAVF. Occlusion of the draining vein, with or without resection of the fistula, is enough to permanently treat these lesions.

Dural Arteriovenous Fistulas

Dural arteriovenous fistulas are most probably acquired lesions. However, they have been rarely encountered de novo. We present a unique case of a 71-year-old woman who initially presented with right-sided dural arteriovenous fistula (DAVF), which spontaneously resolved after diagnostic arteriography. She later developed asymptomatic occlusion of the left transverse sinus. Five years after her initial presentation she developed left-sided pulse-synchronous tinnitus. MRA and catheter angiography showed a complex type IV DAVF between the left transverse sinus and multiple dural branches arising from both left and right external carotid arteries. The left transverse sinus was isolated from the torcula herophili, with stenosis of the sigmoid sinus. Extensive cortical venous drainage was demonstrated. Endovascular cure was effected by polyvinyl alcohol particle and absolute alcohol occlusion of the dominant dural supply, and transvenous coil occlusion of the left transverse sinus. The patient's symptoms resolved almost immediately. This unique case demonstrates that dural sinus occlusion and DAVFs may co-exist, but there may not be a causal relationship. It is likely that both DAVFs and sinus occlusion are manifestations of the same disease process characterised by a pro-thrombotic state and secondary angiogenesis. It is important to recognise that changes in symptomatology, even long after apparent disappearance of a lesion may indicate recurrence, and careful follow up is advocated.

Dural Arteriovenous Fistulas

Objective ‒ to evaluate peculiarities and results of microsurgical treatment of intracranial dural arteriovenous fistulas (DAVF).Materials and methods. A retrospective analysis of microsurgical treatment of 7 patients with DAVF (4 (57. 1%) women and 3 (42.9 %) men, average age ‒ 43.4 years), who were hospitalized and surgically treated at the SO «Scientific-practical Center of endovascular neuroradiology NAMS of Ukraine» from 2016 to 2020, was made. DAVF was drained into the superior sugittal sinus in 4 (57.1 %) patients, transverse and sigmoid sinuses in 2 (28.6 %) cases, in the middle cranial fossa in 1 (14.3 %). According to the Cognard classification there were 3 (42.9 %) DAVFs belong to type IIb, 2 (28.6 %) ‒ to type IIa + b, 1 (14.3 %) DAVF ‒ to type II, 1 (14.3 %) DAVF ‒ to type IV.Results. In 3 (42.9 %) patients were primarily treated with endovascular method. Follow up studies revealed a recurrence of the disease, and microsurgical disconnection was performed. In 4 (57.1 %) cases, endovascular access to superficial DAVF was risky due to anatomical features, and microsurgery was preferred. In all patients, surgical treatment aimed the disconnecting of the shunt. In 1 (14.3 %) case of DAVF the transverse sinus was ligated. In all cases angiographic confirmation of the DAVFs exclusion was performed. In the postoperative period, there was no evidence of an increasing of clinical symptoms. All patients with pulsatile tinnitus and headache noted their regression after surgery.Conclusions. Considering the efficacy of modern endovascular techniques, microsurgery of DAVF has been indicated in cases where endovascular embolization has proven to be no-n-efficient or technically impossible. Among surgical methods of DAVF treatment, there are disconnection of the meningeal arteries directly at the site of the fistula, resection of the abnormal dura mater with feeding vessels, ligation and intersections of the injured venous sinus, skeletonization of the sinus with the feeding dural vessels. Treatment should be performed in all cases of DAVF with cortical venous drainage and progressive symptoms of the disease. The choice of optimal treatment should be made in a multidisciplinary manner, and all possible methods should be taken into consideration.

Background and purpose Dural arteriovenous fistulas (DAVFs) with cortical venous drainage often present with hemorrhage or neurological deficits and prompt treatment is indicated. Disconnection of the draining vein is considered curative. We present the multimodality treatment results of 35 patients with cranial DAVFs with exclusive cortical venous drainage. Materials and methods Between January 2010 and January 2017, 35 consecutive patients with cranial dural fistulas with exclusive cortical venous drainage were treated. There were 27 men and eight women, mean age 68 years (range 45–87). Clinical presentation was hemorrhage in 23 (66%), pulsatile bruit in two (6%), seizures in one (3%) and blurred vision in one (3%). In eight patients (22%), the DAVF was an incidental finding. Location of the DAVFs was convexity in 25 (71%), posterior fossa in eight (23%) and tentorium in two (6%). Results Surgery was performed in four patients with anterior cranial fossa fistulas and in one patient with a tentorial dural fistula. In 30 patients, embolization with Onyx via the arterial route was the primary treatment with complete obliteration in one session in 25 patients. Additional surgical or endovascular sessions were necessary in five patients after incomplete embolization and in one patient after incomplete surgery. Obliteration was confirmed with angiography after three months. There were no procedural complications. Conclusions Patients with dural fistulas with cortical venous drainage were cured with a strategy of arterial endovascular treatment with Onyx and surgery. These techniques were either primarily successful or complementary. There were no complications of treatment.

Dural Arteriovenous Fistulas

Abstract Dural arteriovenous fistulas are abnormal connections of dural arteries to dural veins or venous sinuses originating from within the dural leaflets. They are usually located near or within the wall of a dural venous sinus that is frequently obstructed or stenosed. The dural fistula sac is contained within the dural leaflets, and drainage can be via a dural sinus or retrograde through cortical veins (leptomeningeal drainage). Dural arteriovenous fistulas can occur at any dural sinus but are found most frequently at the cavernous or transverse sinus. Leptomeningeal venous drainage can lead to venous hypertension and intracranial hemorrhage. The various treatment options include transarterial and transvenous embolization, stereotactic radiosurgery, and open surgery. Although many of the advances in dural arteriovenous fistula treatment have occurred in the endovascular arena, open microsurgical advances in the past decade have primarily been in the tools available to the surgeon. Improvements in microsurgical and skull base approaches have allowed surgeons to approach and obliterate fistulas with little or no retraction of the brain. Image-guided systems have also allowed better localization and more efficient approaches. A better understanding of the need to simply obliterate the venous drainage at the site of the fistula has eliminated the riskier resections of the past. Finally, the use of intraoperative angiography or indocyanine green videoangiography confirms the complete disconnection of fistula while the patient is still on the operating room table, preventing reoperation for residual fistulas.

✓ Definitive endovascular treatment of dural arteriovenous fistulas (DAVFs) requires obliteration of the site of the fistula: either the diseased dural sinus or the pial vein. Access to this site is often limited by occlusion of the sinus proximal and distal to the segment containing the fistula. The authors describe a technique in which the mastoid emissary vein is used to gain access to a Borden–Shucart Type II DAVF in the transverse–sigmoid sinus. Recognition of this route of access, if present, may facilitate endovascular treatment of these lesions. Access to the transverse sinus via this approach can be straightforward and may be underused.

We evaluated dural arteriovenous fistulas (DAVF) drains into leptomeningeal vein (LMV) without the venous sinus interposition. This type of DAVF contained the extra-sinusal type DAVF and the DAVF with so-called pure leptomeningeal venous drainage (PLMVD). We studied 15 patients with DAVF that flows into LMVD without passing into the sinus. The subjects were 5 patients with DAVF in the anterior cranial fossa, 2 with DAVF in the tentorium cerebelli, and 3 with DAVF in the craniocervical junction as extra-sinusal type DAVF and 3 with DAVF in the transverse sigmoid sinus and 2 with DAVF in the superior sagittal sinus as DAVF with PLMVD. This type appears to take a very aggressive course. The arterial pressure of the shunt is directly applied to LMV, which causes bending and winding of the vein, eventually varices, inducing intracranial haemorrhage or venous ischemia in the LMV reflux area. Emergency treatment should be performed as soon as possible. Although it is recognized that interruption of the draining vein is very effective, treatment methods such as TAE, direct surgery, and g knife treatment, or their combinations should be carefully chosen for each case.

Endovascular embolization has evolved to become the primary therapeutic option for dural arteriovenous fistulas (DAVFs). While guaranteeing complete occlusion of the fistula orifice, the goal of DAVF embolization is also to ensure the patency of normal cerebral venous drainage. This paper describes a case of successful embolization of a complex DAVF in the superior sagittal sinus with a multistaged approach using a combination of transvenous and transarterial tactics. The strategies and techniques are discussed.

Introduction Endovascular therapy has shown to be safe and effective for the treatment of cerebral dural arteriovenous fistulas; however, recurrence after complete occlusion is not uncommon, and the timing of recurrence remains unknown. Methods A retrospective single-center cohort study was conducted from January 2005 to December 2020. Patients with high-grade (≥Borden II–Cognard IIB) dural arteriovenous fistulas treated with endovascular therapy were included in this study. Clinical and angiographic characteristics were collected for hospitalization and at follow-up. Results A total of 51 patients with a median age of 61 years were studied; 57% were female. High-flow symptoms related to the high-flow fistula were the most common presentation (67%), and 24% presented with intracranial hemorrhage. Transverse-sigmoid (26%) and cavernous (26%) sinuses were the most common dural arteriovenous fistula locations. A total of 40 patients (70%) had middle meningeal arterial feeders and 4 (7%) had deep cerebral venous drainage. The mean number of embolization procedures per patient was 1.4. Transarterial access was the most frequent approach (61%). Onyx alone was the most common embolic agent (26%). Complete occlusion rate was achieved in 46 patients (80.1%). Last mean radiographic follow-up time was 26.7 months for all 57 dural arteriovenous fistulas. Dural arteriovenous fistula recurrence after radiographic resolution at last treatment was seen in six cases (6/46, 13.1%). Mean time for recurrence was 15.8 months. Mean time of last clinical follow-up was 46.1 months for the 51 patients (100%). A total of 10 (20%) experienced any procedural complications, among which two (4%) became major thromboembolic events. Conclusion Endovascular therapy is safe and effective for the treatment of high-grade dural arteriovenous fistulas. Given the significant recurrence rate of embolized dural arteriovenous fistulas even after 2 years, long-term angiographic follow-up might be needed.
