[Ab] Resumo:In interventional neuroradiology, endovascular embolization represents an important and helpful tool in the treatment of multiple head and neck diseases. These interventional procedures may be performed with curative intent, to reduce the surgical risk within a multimodal treatment concept, or to improve or at least maintain a good quality of life within a palliative therapy concept. In addition to a good understanding of disease pathology, knowledge of vascular anatomy, including collateral vessels and dangerous extracranial-intracranial anastomoses, is essential for successful treatment, as is implementation of an established technique using appropriate material. Indications for endovascular embolization are i. otherwise unmanageable bleeding (caused by e. g., trauma, vascular malformation, or tumor), ii. reduction of perioperative bleeding by preoperative embolization in case of a hypervascularized tumor, iii. selective induction of tumor necrosis by palliative embolization to enhance local tumor control. Major complications such as stroke, loss of vision, and cranial nerve palsy are mostly due to a lack of preinterventional evaluation. Regarding neurological deficits, interventions within the supply region of the external carotid artery have a complication rate below 1%.

[Ti] Título:Straight sinus dural arteriovenous fistula presenting with reversible parkinsonism: A case report and literature review.

[Ab] Resumo:RATIONALE: A dural arteriovenous fistula (DAVF) refers to an abnormal direct connection between an intracranial artery and a dural venous sinus. A DAVF presenting with parkinsonism is rare, and is therefore easily misdiagnosed. Therefore, early consideration of DAVF in the differential diagnosis of reversible parkinsonism is necessary. PATIENT CONCERNS: We present the case of a 51-year-old male with progressive parkinsonism. DIAGNOSES: He was diagnosed as straight sinus occlusion. Imaging studies revealed a DAVF associated with cerebral hypoperfusion of the lenticular nuclei and frontal lobe white matter. INTERVENTIONS: Endovascular embolization was performed through his left occipital artery. OUTCOMES: Treatment resulted in marked clinical improvement that a major improvement of parkinsonism was observed concomitant with no evidence of early venous drainage of this patient. LESSONS: DAVF should always be considered as a potential cause of progressive parkinsonism on account of its potential reversibility. Our case suggests a concomitant role of basal ganglia degeneration and frontal white matter hypoperfusion in the pathology of parkinsonism due to DAVF. However, the precise pathophysiology remains to be investigated.

[Ab] Resumo:BACKGROUND: Dural arteriovenous fistulas (dAVFs) often are treated via transarterial or transvenous embolization. Incomplete penetration of the draining vein/occult residual often will become apparent on follow-up angiography, requiring repeat embolization, or at times, surgical resection. CASE DESCRIPTION: A 41-year-old woman presented with cerebellar hemorrhage from a tentorial dAVF treated with transvenous coil embolization. Follow-up angiography disclosed a residual/recurrent fistula treated with transvenous Onyx embolization. After further follow-up angiography demonstrated another occult residual/recurrence, the fistula was disconnected with the tentorial dura excised via a retrosigmoid approach. Six-month follow-up angiography demonstrated no recurrence. CONCLUSIONS: Although endovascular treatment of dAVFs is generally first-line therapy, surgical disconnection of fistulas, particularly high-risk residual/recurrent fistulas, is an excellent option in well-selected cases.

[Ab] Resumo:BACKGROUND: Although multifocal spinal arteriovenous malformations (AVMs) have been reported before, the present case is the first case of 2 different types, including 1 perimedullary arteriovenous fistula and 2 spinal dural arteriovenous fistulas of lumbosacral AVMs, coexisting in 1 patient. We also report the use of hybrid techniques in treatment of concomitant lumbosacral spinal AVMs. CASE DESCRIPTION: A 65-year-old man presented with a 4-year history of progressive sensory, motor, and sphincter dysfunction. Spinal magnetic resonance imaging and digital subtraction angiography showed 2 spinal dural arteriovenous fistulas (fed by the right L2 lumbar artery and the right lateral sacral artery, respectively) and 1 perimedullary arteriovenous fistula (fed by the filum terminale artery from the left L2 lumbar artery [i.e., filum terminale arteriovenous fistulas]. A hybrid technique was used to perform embolization of the right L2 spinal dural arteriovenous fistula and microsurgery of the L5 level filum terminale vein. The patient was asymptomatic 1 year later. CONCLUSIONS: Multifocal spinal vascular malformations may coexist in 1 case, and standardized spinal digital subtraction angiography, including the bilateral internal iliac arteries and median sacral artery, should be performed to avoid a missed diagnosis. The concomitant phenomenon indicates that venous hypertension may be a risk factor for the development of arteriovenous fistulas. Hybrid techniques are effective in treatment of multifocal and complex spinal AVMs.

[Ti] Título:Pial-Dural Intracranial Arteriovenous Fistula with Flow-Associated Aneurysmal Rupture-Case Report with Review of Literature and Proposal on the Mechanism of Hemorrhage and Treatment Options.

[Ab] Resumo:BACKGROUND: Vascular anomalies in the form of dural arteriovenous fistulas (DAVFs), arteriovenous malformations, and aneurysms are well described in the literature. Pial arteriovenous fistulas (PAVFs) are described to a lesser extent in the literature. When these anomalies are combined, diagnosis and treatment become complex. CASE DESCRIPTION: A 55-year-old man presented with PAVF/DAVF with a ruptured flow-related aneurysm in the distal left posterior inferior cerebellar artery, which required surgical clipping and disconnection. We performed a PubMed search of all identifiable cases of PAVFs in adults. We then identified which cases had components of DAVFs and flow-related aneurysms. We identified 51 PAVF cases and identified which patients presented with hemorrhage and the treatment modalities of all cases. Of 51 cases identified, 4 were a DAVF/FRA, and 5 were a PAVF/DAVF. One case of PAVF/DAVF/FRA was identified. CONCLUSIONS: The exact mechanism of PAVF/DAVF formation is unknown. Hemorrhage predilection of PAVF/DAVF is more difficult to predict than a sole fistula, likely secondary to the complex flow dynamics. To our knowledge, this literature review is the largest review to date regarding PAVFs in adult patients and can provide insight into decision making when evaluating treatment options.

[Ab] Resumo:Spinal vascular malformations are uncommon yet important spinal pathologies commonly classified in congenital and acquired lesions. Spinal lipomas consist of three subtypes: intramedullary lipomas, lipomyelo(meningo)celes and lipomas of the filum. Although the association of spinal arteriovenous malformations (AVM) with other congenital anomalies is well known, the coexistence of dural arteriovenous fistulas (AVF) and tethered spinal cord is exceptionally rare and only eight cases have been reported. We present two cases from our institution and speculate on the possible origin of such a rare but insidious association. We review the current literature with a focus on possible pitfalls in diagnosis and treatment.

[Ti] Título:Newly Detected Cervical Spinal Dural Arteriovenous Fistula on Magnetic Resonance Angiography Causing Intracranial Subarachnoid Hemorrhage.

[Ab] Resumo:BACKGROUND: Although an asymptomatic spinal dural arteriovenous fistula (SDAVF) can sometimes be incidentally detected on magnetic resonance imaging (MRI), there are no previous reports showing the development of an SDAVF on MRI or magnetic resonance angiography (MRA). CASE DESCRIPTION: A 64-year old man with unruptured vertebral artery dissection (VAD) developed a subarachnoid hemorrhage (SAH) during regular follow-up. Emergent endovascular coil internal trapping for the VAD was performed; however, angiography after the endovascular treatment showed a lower cervical SDAVF. The SDAVF was considered the bleeding source based on subsequent spinal MRI, and endovascular embolization was performed. In this case, previous serial MRA examinations indicated that the SDAVF appeared for the first time during follow-up, and SAH occurred. CONCLUSIONS: This may be the first report in which serial MRA studies demonstrated the course of this condition, from the appearance of an SDAVF to the development of SAH. An abnormal vascular structure detected on MRA indicated abnormal enlargement of the perimedullary vein and the presence of a cervical SDAVF. A lower cervical SDAVF should be suspected if such an abnormal vascular structure is detected on MRA.

[Ab] Resumo:BACKGROUND: Spinal dural arteriovenous fistula (DAVF) is a rare disease, and multiple concurrent lesions are extremely rare. Such multiple spinal DAVFs have similar outflow routes at neighboring levels. However, there have been no reported cases of remote lesions of multiple spinal DAVFs. The authors herein report a case of double synchronous cervical and sacral DAVFs. CASE DESCRIPTION: A 56-year-old man with no previous history of disease presented with progressive myelopathy, and spinal magnetic resonance imaging showed extensive edema of the spinal cord from the conus to T7. The initial angiography incidentally revealed a C1 DAVF, but the sacral DAVF was not diagnosed. The C1 DAVF was treated surgically, because of the risk of subarachnoid hemorrhage. A second angiography was performed 2 months after the first surgery because of high clinical suspicion, and the sacral DAVF was diagnosed at that time. The sacral DAVF was treated surgically, and the symptoms gradually resolved within 6 months after surgery. CONCLUSIONS: Spinal DAVF is a rare disease, but clinicians should be aware of the possibility of the concurrence of multiple spinal fistulas located at different levels in the same patient.

[Ab] Resumo:Introduction In case of cavernous sinus dural arteriovenous fistula (CSDAVF), transvenous embolization (TVE) of the cavernous sinus (CS) via the inferior petrosal sinus (IPS) is generally performed. However, various approach routes have been reported when the accessibility of the IPS is challenging. We herein report a case of CSDAVF treated by TVE with direct puncture of the facial vein. Case report A 70-year-old woman who suffered from tinnitus, chemosis, diplopia and bruit was referred to our hospital. Digital subtraction angiography (DSA) demonstrated CSDAVF. We initially attempted to perform TVE via the IPS route; however, we could not guide a catheter to the CS because of an anatomical difficulty. Then, we performed percutaneous direct puncture of the dilated facial vein, and successfully treated the patient. Conclusion When navigating microcatheter to the CS is difficult because of an anatomical difficulty of the IPS, direct puncture of the facial vein is a feasible route.

[Ab] Resumo:Purpose To investigate whether sinovenous outflow restriction (SOR) is more strongly associated with hemorrhage than cortical venous reflux (CVR) in patients with lateral sinus dural arteriovenous fistulas (DAVFs). Materials and Methods An institutional review board approved this retrospective study and waiver of informed consent was obtained. From 1995 to 2016, 163 cases of lateral sinus DAVFs were included and divided into hemorrhagic and nonhemorrhagic groups based on initial presentation. Their angiograms and magnetic resonance images were evaluated, with two evaluators independently grading CVR and SOR. The SOR was scored as the combined conduit score (CCS), ranging from zero (total occlusion) to 8 (fully patent). The CVR and CCS of the hemorrhagic and nonhemorrhagic groups were compared. Logistic regression models were established for both the CVR and CCS to compare their performances in discriminating DAVF hemorrhage. Results Sinovenous outflow was significantly more restrictive (lower median CCS) in the hemorrhagic group than in the nonhemorrhagic group (1 vs 6.5; P < .001). A CCS of less than or equal to 2 best discriminated between the groups with a sensitivity of 90.0% and a specificity of 88.1%. The CCS model had a higher discriminative performance than did the CVR model (area under the curve, 0.933 vs 0.843; P = .018). Conclusion The CCS grading system semiquantifies SOR. SOR may represent a stronger risk factor associated with hemorrhage in patients with lateral sinus DAVFs than does CVR, and thus may offer guidance in therapeutic decision making. RSNA, 2017.
