✓ Intracranial dural arteriovenous (AV) fistulas with spinal perimedullary venous drainage are rare lesions that have distinctive clinical, radiological, and therapeutic aspects. Five patients presented with an ascending myelopathy, which extended to involve the brain stem in three cases. Myelography and magnetic resonance imaging showed slightly dilated spinal perimedullary vessels. Spinal angiograms were normal in the arterial phase. Diagnosis was only possible after cerebral angiography, which demonstrated posterior fossa AV fistulas fed by meningeal arteries and draining into spinal perimedullary veins. Endovascular treatment alone resulted in angiographic obliteration of the lesion in three patients. Two patients required surgery in addition to endovascular therapy. One patient died postoperatively, and in one a transient complication of embolization was observed. Improvement after treatment was good in two cases and fair in two. Transverse sinus thrombosis was observed in three cases and was probably the cause of the aberrant venous drainage of the fistula into the spinal perimedullary veins. The pathophysiology is related to spinal cord venous hypertension. These lesions were classified as Type 5 in the Djindjian and Merland classification of dural intracranial AV fistulas. Endovascular therapy is a safe effective method in the treatment of these fistulas and should be tried first.

Cortical Venous Drainage

✓ Dural arteriovenous (AV) fistulas are thought to be acquired lesions that form in an area of thrombosis within a sinus. If the sinus remains completely thrombosed, venous drainage from these lesions occurs through cortical veins, or, if the sinus is open, venous drainage is usually into the involved sinus. Among 105 patients with dural A V fistulas evaluated over the the past 5 years, seven had a unique type of dural AV fistula in the superior sagittal, transverse, or straight sinus in which only cortical venous drainage occurred despite a patent involved sinus; the fistula was located within the wall of a patent dural sinus, but outflow was not into the involved sinus. This variant of dural AV fistulas puts the patient at serious risk for hemorrhage or neurological dysfunction caused by venous hypertension. Three patients presented with hemorrhage, one with progressive neurological dysfunction, one with seizures, and two with bruit and headaches. A combination of surgical and endovascular techniques was used to close the fistula while preserving flow through the sinus.

Abstract We examined and managed two patients with posterior fossa dural arteriovenous malformations (DAVMs) and papilledema. Both DAVMs had venous drainage into the transverse, straight, and sigmoid dural venous sinuses. The mechanism of papilledema in the first case was presumed venous hypertension resulting in impaired cerebrospinal fluid absorption, as the malformation drained into the single transverse sinus. This was cured by selective arterial embolization of the causative DAVM. The second patient had venous sinus thrombosis that impaired venous drainage despite embolization. A lumboperitoneal shunt was necessary to treat the elevated intracranial pressure.

Object. Transvenous embolization is effective in the treatment of an intracranial dural arteriovenous fistula (DAVF). Access to the fistula via the internal jugular vein (IJV) may be limited by associated dural sinus thrombosis; a transcranial approach has been developed for venous embolization in such a situation. The authors report their experiences with the use of a transcranial approach for venous embolization of DAVFs. Methods. Ten patients with DAVFs underwent craniectomy and embolization procedures in which direct sinus puncture was performed. The DAVFs were located inside the dura mater that constituted the walls of the transverse sinus in five cases, the superior sagittal sinus in four cases, and the superior petrosal sinus in one case. All DAVFs drained directly into a sinus with secondary reflux into leptomeningeal veins. In all cases, the fistula could not be accessed from the IJVs. Craniectomy was performed in an operating room and, in seven cases, subsequent enlargement of the craniectomy was required. Sinus catheterization was performed after the patient had been transferred to the angiography room. The DAVFs were embolized using coils only in five patients, glue only in two patients, and both coils and glue in three patients. Angiographic confirmation that embolization of the fistula was successful was obtained in all cases. A transient complication occurred during the first case after sinus catheterization was attempted in the operating room. Conclusions. The transcranial approach allows straightforward access to DAVFs located on superficial dural sinuses that are inaccessible from the IJVs. The effectiveness of this approach is similar to that of the standard retrograde venous approach. The correct location and adequate extent of the craniectomy are essential for success to be achieved using this technique.

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.

✓ The authors describe their experience with four cases of dural arteriovenous malformation (AVM) which led them to analyze the clinical aspects of these lesions in an attempt to understand their pathophysiology. An additional 191 previously reported cases of dural AVM's were reviewed with special attention to the mechanism of intradural, central, and peripheral nervous system manifestations. Apart from the peripheral cranial nerve symptoms, which are most likely due to arterial steal, the central nervous system (CNS) symptoms appear to be related to passive venous hypertension and/or congestion. Generalized CNS symptoms can be related to cerebrospinal fluid malabsorption due either to increased pressure in the superior sagittal sinus, to venous sinus thrombosis, or to meningeal reaction resulting from minimal subarachnoid hemorrhages. These phenomena are not related to the anatomical type of venous drainage. On the other hand, focal CNS symptoms are specifically indicative of cortical venous drainage. Seizures, transient ischemic attacks, motor weakness, and brain-stem and cerebellar symptoms can be encountered depending on the territory of the draining vein or veins. Therefore, the localizing value of focal CNS symptomatology relates to the venous territory and not to the nidus or to the arterial supply characteristics of dural AVM's. Furthermore, the venous patterns of various dural AVM's at the base of the skull are expressed by differences in their clinical presentation. Dural AVM's of the floor of the anterior cranial fossa and of the tentorium are almost always drained by the cortical veins and, therefore, have a high risk of intradural bleeding. The remarkable similarities in the manifestations of dural and brain AVM's and the differences in the manifestations of dural and spinal dural AVM's are pointed out. High-quality angiograms and a multidisciplinary approach to the study of dural AVM's will provide the best understanding of their symptoms and, therefore, the most appropriate treatment strategy.

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.

Gain Access

✓ 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.

Mechanical Thrombolysis

Purpose Cerebral venous sinus thrombosis (CVST) is an unusual and potentially life-threatening condition with variable and nonspecific clinical symptoms and high morbimortality rates. Standard therapy consists of systemic anticoagulation; although there is no clear evidence about the best choice for treatment, intravenous heparin is used as the first-line treatment modality. Intravenous sinus thrombolysis can be an effective and relatively safe treatment for acutely deteriorating patients who have not responded to conventional therapy. This case report presents the possibility of endovascular treatment in multiple steps with mechanical thrombolysis with balloon, local pharmacological thrombolysis and stenting, in a patient with a severe form of CVST. Case summary A 67-year-old woman presented severe headache, agitation and confusion with diagnosis of venous sinus dural thrombosis in both lateral sinus and torcula. After 24 h there was neurological worsening evolving with seizures and numbness even after starting heparin, without sinus recanalization; CT scan showed left temporal intracerebral hemorrhage. We decided to take an endovascular approach in multiple steps. The first step was mechanical static thrombolysis with balloon; the second step was dynamic mechanical thrombolysis with a balloon partially deflated and “pulled”; the third step was local thrombolysis with Actilyse™; finally, the fourth step was angioplasty and reconstruction of the sinuses using multiple carotid stents and complete angiographic recanalization of both sinuses and torcula. After 24 h of endovascular treatment there was full clinical recovery and no tomographic complications. Conclusion This result shows that mechanical clot disruption, intrasinus thrombolysis and reconstruction of wall sinuses with stenting can be an endovascular option in the severe form of CVST with intracerebral hemorrhage and rapid worsening of neurological symptoms. Although this type of treatment can re-channel the occluded sinuses, further comparative and randomized studies are needed to clarify its efficacy versus other therapeutic modalities.

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.
