Abstract: Arteriovenous fistulae present in any of a number of characteristic locations in the brain, such as the ethmoidal region, the petrosal sinus, and the transverse sinus and torcula. The fistula is an abnormal connection between an artery and vein. While there are multiple accepted classification systems, the risk they represent to the patient depends primarily on the degree of reflux of the venous drainage back to the cortex of the brain. While the inflow and outflow may be very complex, isolation of the fistulous point where this abnormal connection occurs is the key to successful treatment. This may be achieved through either endovascular or open surgical techniques deoending on the anatomy.

Background There is no consensus as to whether balloon angioplasty alone or stent placement is effective for sinus occlusion associated with dural arteriovenous fistula (DAVF). Herein, we first report a case of transverse sinus occlusion associated with DAVF in which gradual sinus dilatation was observed after balloon angioplasty with embolization of the affected sinus with shunt flow. Case presentation A 69-year-old man presented with executive dysfunction. Magnetic resonance imaging revealed left transverse sinus–sigmoid sinus DAVF with occlusion of the left jugular vein and right transverse sinus. Before endovascular treatment, the patient had symptomatic epilepsy and subarachnoid hemorrhage. Retrograde leptomeningeal venous drainage disappeared with packing of the left transverse sinus–sigmoid sinus. Subsequently, balloon angioplasty of the right occluded transverse sinus was performed to maintain the normal venous drainage and remaining shunt outflow. Dilatation of the right transverse sinus was poor immediately after surgery. However, angiography after 10 days and 6 months revealed gradual dilatation of the right transverse sinus. Conclusion Sinus occlusion, which is thought to be caused by sinus hypertension associated with DAVF rather than chronic organized thrombosis or thrombophilia, may dilate over time after balloon angioplasty and shunt flow reduction if occluded sinus is necessary for facilitating normal venous drainage.

BackgroundThere is a lack of consensus in the management of arteriovenous malformations (AVMs) of the brain since ARUBA (A Randomised trial of Unruptured Brain Arteriovenous malformations) trial showed that medical management is superior to interventional therapy in patients with unruptured brain AVMs. The treatment of brain AVM is associated with significant morbidity.Objectives and methodsA review was done to determine the behaviour of brain AVMs and analyse the risks and benefits of the available treatment options. A search was done in the literature for studies on brain AVMs. Descriptive analysis was also done.ResultsThe angiogenic factors such as vascular endothelial growth factor and inflammatory cytokines are involved in the growth of AVMs. Proteinases such as matrix metalloproteinase-9 contribute to the weakening and rupture of the nidus. The risk factors for haemorrhage are prior haemorrhage, deep and infratentorial AVM location, exclusive deep venous drainage and associated aneurysms. The advancements in operating microscope and surgical techniques have facilitated microsurgery. Stereotactic radiosurgery causes progressive vessel obliteration over 2–3 years. Endovascular embolisation can be done prior to microsurgery or radiosurgery and for palliation.ConclusionsSpetzler-Martin grades I and II have low surgical risks. The AVMs located in the cerebellum, subarachnoid cisterns and pial surfaces of the brainstem can be treated surgically. Radiosurgery is preferable for deep-seated AVMs. A combination of microsurgery, embolisation and radiosurgery is recommended for deep-seated and Spetzler-Martin grade III AVMs. Observation is recommended for grades IV and V.

Pial Arteriovenous Fistula

ABSTRACT BACKGROUND AND IMPORTANCE The etiology of de novo pial arteriovenous fistula (AVF) is unknown. We found 2 cases of de novo pial AVF, which appeared after cerebral infarction and which was associated with venous hypertension secondary to venous sinus thrombosis with a dural AVF (dAVF). Additional angiogenic stimuli (second hit) were considered as one of the mechanisms of de novo pial AVF. CLINICAL PRESENTATION A 63-yr-old male was admitted to our hospital due to an intraventricular hemorrhage. He had a history of cerebral infarction 2 yr before. Angiography demonstrated multiple dAVFs with bilateral occlusion of the distal transverse sinus associated with prominent retrograde cortical venous drainage. A pial AVF was found at the border of his previous cerebral infarction. Both lesions were successfully treated using endovascular technique. A second case involved a 47-yr-old female who was admitted to our hospital due to venous infarction also associated with sinus thrombosis. De novo pial AVF at the border of the venous infarction and dAVF at the transverse sigmoid junction were demonstrated on angiography 6 mo later. CONCLUSION We speculate that venous hypertension associated with additional angiogenic stimuli (second hit) due to brain ischemia and/or brain injury related to infarction caused de novo pial AVF in these 2 cases.

We report the endovascular treatment of a symptomatic dural arteriovenous fistula in a 61-year-old male patient. The medial portion of the fistula was occluded with detachable platinum coils during an initial intervention using a transvenous approach. Due to persistence of the symptoms in a second intervention eight months later the fistula was completely occluded by the transvenous introduction of a liquid embolic agent (Onyx 500+). The liquid embolic agent was introduced under protection by the temporary balloon occlusion of the fistula's venous drainage. After the procedure, the patient was treated for three months with 75 mg clopidogrel (Plavix®) and with 100 mg acetylsalicylic acid (ASS®). A few days after the intervention, the patient was discharged without any neurological deficit and in good clinical condition. The follow-up examination six months later neither detected a recurrence of the dural arteriovenous fistula in the angiogram nor any neurological symptoms.

Abstract BACKGROUND AND IMPORTANCE: We describe a novel technique that uses a goose neck snare for microcatheterization at transvenous embolization (TVE) for dural arteriovenous fistulae (dAVF). We have named our method the “remora technique.” CLINICAL PRESENTATION: A 48-year-old man reported with dizziness. Angiography disclosed a transverse-sigmoid sinus (T-SS) dAVF with proximal sigmoid sinus occlusion, an open distal transverse sinus, narrow multiple divided confluence sinus, and multiple retrograde leptomeningeal venous drainage. We attempted TVE via the confluence sinus from the contralateral open side; it was narrow, steep, and divided into cavities, rendering the procedure very difficult. Although we were able to pass a 0.035-inch guidewire to the affected transverse sinus, we could not advance via the same route with the microguidewire. One month later we attempted transfemoral TVE again using the remora technique. We caught the 0.035-inch guidewire in the left internal jugular vein with a goose neck micro snare bearing a microcatheter. By advancing the 0.035-inch wire across the confluence sinus to the affected sinus, we were able to pass the microcatheter through the lesion using the snare like a remora. We then performed transvenous coil packing. CONCLUSION: In TVE for dAVF, passage of the microguidewire is often difficult. Even if the affected sinus can be reached with the stiff 0.035-inch guidewire, it may not be possible to follow with the microguidewire. We report on a patient with T-SS dAVF who underwent successful microcatheterization in which we used our remora technique with a goose neck snare.

Rationale and Objectives The marginal sinus is an infrequently recognized dural venous sinus at the rim of the foramen magnum. Recognition of this sinus and knowledge of its anatomy will enable the neurointerventionalist to treat dural arteriovenous fistulae (AVF) involving the marginal sinus. Methods We present a report of the signs, symptoms, angiographic appearance, and treatment results of two patients with marginal sinus dural AVF. In addition, we review the literature concerning the marginal sinus and describe the anatomy of this region. Angiograms depicting normal variants are presented to illustrate the various patterns that may be encountered when the marginal sinus participates in the venous drainage of the cranium. Results In two patients with dural arteriovenous fistulae (AVF) the marginal sinus was found to be the venous receptacle. The marginal sinuses are dural venous sinuses located at the lateral margins of the foramen magnum. Superiorly, the marginal sinus connects to the occipital sinus, a single or paired midline venous channel arising at the torcular Herophili or the medial transverse sinus. The marginal sinus typically drains into the sigmoid sinus, and may connect to the condylar veins, the superior aspect of the internal venous plexus, or the occipital plexus. Occasionally, the occipital-marginal sinus system represents the primary drainage pathway of the cranium, completely replacing the transverse sinus. In the two patients we treated with dural AVF in this location, simple transvenous packing of the sinus effectively cured the lesion. Conclusions The marginal sinus is a dural venous sinus that can rarely be involved with a dural AVF. Recognition that a dural AVF involves the marginal sinus can facilitate safe, effective therapy.

Background: Onyx has already been reported as an effective and safe agent in transarterial embolization of cranial dural arteriovenous fistula (d-AVF). However, successful treatment is related to not only complete shunt obliteration but also preservation of a normal route of venous drainage. Here, we present a case of transverse sigmoid d-AVF in which successful treatment was achieved by transarterial Onyx embolization with targeted balloon protection of the venous drainage. Case Description: A 70-year-old man presented with a 3-month history of tinnitus in the left ear and mild headache. Magnetic resonance imaging (MRI) showed a cluster of abnormal blood vessels in the area of the left transverse sinus (TS)-sigmoid sinus (SS) junction. Cerebral angiography demonstrated a Cognard type IIa d-AVF at the left TS-SS junction, supplied mainly by vessels such as the left middle meningeal artery, left occipital artery, and left meningohypophyseal trunk. In the venous phase, the ipsilateral TS-SS was recognized as a functional sinus and the left vein of Labbe drained into the TS near the drainage channel. Based on these findings, we decided to perform endovascular treatment under a transarterial approach with Onyx using targeted balloon protection of the venous sinus to protect against Onyx migration and preserve antegrade sinus flow. The patient recovered well without sequelae, and follow-up MRI 12 months later showed complete disappearance of the d-AVF. Conclusion: This treatment strategy using targeted balloon protection may be very useful to preserve antegrade sinus flow in patients with Cognard type IIa d-AVF.

Abstract BACKGROUND: Hemorrhage from cerebral dural arteriovenous fistulae (dAVF) is a considerable source of neurological morbidity and even mortality. OBJECTIVE: To evaluate the natural history of cerebral dAVF. METHODS: We reviewed our own cohort of 70 dAVF and incorporated results from the literature, synthesizing pooled hemorrhage rates and evaluating risk factors for 395 dAVF in 6 studies. RESULTS: No hemorrhages occurred during 409 lesion-years of follow-up of Borden type I dAVF; however, cortical venous drainage developed in 1.4%. Like type I dAVF, type II dAVF demonstrated a female predilection and were most commonly transverse-sigmoid or cavernous. Eighteen percent of type II dAVF presented with hemorrhage (95% confidence interval [CI]: 8%-36%), and the annual hemorrhage rate was 6% (95% CI: 0.1%-19%). Borden type III dAVF demonstrated a male predilection and were most commonly tentorial or petrosal. Thirty-four percent presented with hemorrhage (95% CI: 0.4%-49%), with an annual hemorrhage rate of 10% (95% CI: 4%-20%), increasing to 21% for those with venous ectasia (95% CI: 4%-66%). The hemorrhage rate decreased to 2% for asymptomatic or minimally symptomatic type II or III dAVF (95% CI: 0.2%-8%), and increased to 10% for those presenting with nonhemorrhagic neurological deficits (95% CI: 0.9%-41%) and to 46% for those presenting with hemorrhage (95% CI: 11%-130%). CONCLUSION: Venous ectasia is a significant risk factor for hemorrhage among dAVF with cortical venous drainage. In addition, those with hemorrhagic presentation, even compared with nonhemorrhagic neurological deficit presentation, as well as Borden type III dAVF compared with type II dAVF demonstrated a trend toward greater hemorrhage rates.
