Congenital, inherited, or acquired abnormalities involving ARTERIES; VEINS; or venous sinuses in the BRAIN; SPINAL CORD; and MENINGES.
A spectrum of congenital, inherited, or acquired abnormalities in BLOOD VESSELS that can adversely affect the normal blood flow in ARTERIES or VEINS. Most are congenital defects such as abnormal communications between blood vessels (fistula), shunting of arterial blood directly into veins bypassing the CAPILLARIES (arteriovenous malformations), formation of large dilated blood blood-filled vessels (cavernous angioma), and swollen capillaries (capillary telangiectases). In rare cases, vascular malformations can result from trauma or diseases.
Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital arteriovenous fistula. The lack of blood flow and oxygen in the capillaries can lead to tissue damage in the affected areas.
Congenital vascular anomalies in the brain characterized by direct communication between an artery and a vein without passing through the CAPILLARIES. The locations and size of the shunts determine the symptoms including HEADACHES; SEIZURES; STROKE; INTRACRANIAL HEMORRHAGES; mass effect; and vascular steal effect.
The main information-processing organs of the nervous system, consisting of the brain, spinal cord, and meninges.
A vascular anomaly due to proliferation of BLOOD VESSELS that forms a tumor-like mass. The common types involve CAPILLARIES and VEINS. It can occur anywhere in the body but is most frequently noticed in the SKIN and SUBCUTANEOUS TISSUE. (from Stedman, 27th ed, 2000)
An autosomal dominant vascular anomaly characterized by telangiectases of the skin and mucous membranes and by recurrent gastrointestinal bleeding. This disorder is caused by mutations of a gene (on chromosome 9q3) which encodes endoglin, a membrane glycoprotein that binds TRANSFORMING GROWTH FACTOR BETA.
A vascular anomaly composed of a collection of large, thin walled tortuous VEINS that can occur in any part of the central nervous system but lack intervening nervous tissue. Familial occurrence is common and has been associated with a number of genes mapped to 7q, 7p and 3q. Clinical features include SEIZURES; HEADACHE; STROKE; and progressive neurological deficit.
Congenital or acquired structural abnormalities of the lymphatic system (LYMPHOID TISSUE) including the lymph vessels.

Diseases of any component of the brain (including the cerebral hemispheres, diencephalon, brain stem, and cerebellum) or the spinal cord.
A vascular anomaly that is a collection of tortuous BLOOD VESSELS and connective tissue. This tumor-like mass with the large vascular space is filled with blood and usually appears as a strawberry-like lesion in the subcutaneous areas of the face, extremities, or other regions of the body including the central nervous system.
Endoscopy of the small intestines accomplished while advancing the endoscope into the intestines from the stomach by alternating the inflation of two balloons, one on an innertube of the endoscope and the other on an overtube.
An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.

A vascular malformation of developmental origin characterized pathologically by ectasia of superficial dermal capillaries, and clinically by persistent macular erythema. In the past, port wine stains have frequently been termed capillary hemangiomas, which they are not; unfortunately this confusing practice persists: HEMANGIOMA, CAPILLARY is neoplastic, a port-wine stain is non-neoplastic. Port-wine stains vary in color from fairly pale pink to deep red or purple and in size from a few millimeters to many centimeters in diameter. The face is the most frequently affected site and they are most often unilateral. (From Rook et al., Textbook of Dermatology, 5th ed, p483)
Veins draining the cerebrum.
Acquired degenerative dilation or expansion (ectasia) of normal BLOOD VESSELS, often associated with aging. They are isolated, tortuous, thin-walled vessels and sources of bleeding. They occur most often in mucosal capillaries of the GASTROINTESTINAL TRACT leading to GASTROINTESTINAL HEMORRHAGE and ANEMIA.
A congenital disorder that is characterized by a triad of capillary malformations (HEMANGIOMA), venous malformations (ARTERIOVENOUS FISTULA), and soft tissue or bony hypertrophy of the limb. This syndrome is caused by mutations in the VG5Q gene which encodes a strong angiogenesis stimulator.

A group of congenital malformations involving the brainstem, cerebellum, upper spinal cord, and surrounding bony structures. Type II is the most common, and features compression of the medulla and cerebellar tonsils into the upper cervical spinal canal and an associated MENINGOMYELOCELE. Type I features similar, but less severe malformations and is without an associated meningomyelocele. Type III has the features of type II with an additional herniation of the entire cerebellum through the bony defect involving the foramen magnum, forming an ENCEPHALOCELE. Type IV is a form a cerebellar hypoplasia. Clinical manifestations of types I-III include TORTICOLLIS; opisthotonus; HEADACHE; VERTIGO; VOCAL CORD PARALYSIS; APNEA; NYSTAGMUS, CONGENITAL; swallowing difficulties; and ATAXIA.

A vascular anomaly characterized by a radial or wedge-shaped arrangement of dilated VEINS draining into a larger vein in the brain, spinal cord, or the meninges. Veins in a venous angioma are surrounded by normal nervous tissue, unlike a CENTRAL NERVOUS SYSTEM CAVERNOUS HEMANGIOMA that lacks intervening nervous tissue. Drainage of venous angioma is fully integrated with the body's venous system, therefore, in most cases there is no clinical signs and rare bleeding.
A condition with multiple tumor-like lesions caused either by congenital or developmental malformations of BLOOD VESSELS, or reactive vascular proliferations, such as in bacillary angiomatosis. Angiomatosis is considered non-neoplastic.
Permanent dilation of preexisting blood vessels (CAPILLARIES; ARTERIOLES; VENULES) creating small focal red lesions, most commonly in the skin or mucous membranes. It is characterized by the prominence of skin blood vessels, such as vascular spiders.

The vessels carrying blood away from the capillary beds.
A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.
A neoplasm derived from blood vessels, characterized by numerous prominent endothelial cells that occur singly, in aggregates, and as the lining of congeries of vascular tubes or channels. Hemangioendotheliomas are relatively rare and are of intermediate malignancy (between benign hemangiomas and conventional angiosarcomas). They affect men and women about equally and rarely develop in childhood. (From Stedman, 25th ed; Holland et al., Cancer Medicine, 3d ed, p1866)
Usually a benign tumor, that commonly presents as a solitary blue nodule with spindled MELANOCYTES covered by smooth SKIN. Several variants have been identified, one variant being malignant. The blue color is caused by large, densely packed melanocytes deep in the DERMIS of the nevus. In CHILDREN, they usually occur on the BUTTOCKS and LUMBOSACRAL REGION and are referred to as cellular blue nevi. Malignant blue nevi are more commonly found on the SCALP.

Clinically aggressive diffuse capillary telangiectasia of the brain stem: a clinical radiologic-pathologic case study. (1/221)

Capillary malformations or telangiectasias of the brain usually exhibit a benign clinical course, although occassionally they may be associated with mild to moderate symptomatology of uncertain origin. We report a case of an exceptionally aggressive capillary telangiectasia in a child, which was associated with progressive neurologic deterioration resulting in death.  (+info)

Cerebrovascular manifestations in 321 cases of hereditary hemorrhagic telangiectasia. (2/221)

BACKGROUND AND PURPOSE: Patients with hereditary hemorrhagic telangiectasia (HHT) are at risk for developing cerebral vascular malformations and pulmonary arteriovenous fistulae. We assessed the risk of neurological dysfunction from these malformations and fistulae. METHODS: Three hundred twenty-one consecutive patients with HHT seen at a single institution over a 20-year period were studied. Any evidence of prior neurological symptoms or presence of an intracranial vascular malformation was recorded. All cases of possible cerebral arteriovenous malformation were confirmed by conventional arteriography. RESULTS: Twelve patients (3.7%) had a history of cerebral vascular malformations. Ten patients had arteriovenous malformations, 1 had a dural arteriovenous fistula, and 1 had a cavernous malformation. Seven patients (2.1%) presented with intracranial hemorrhage, 2 presented with seizures alone, and 3 were discovered incidentally. The average age at the time of symptomatic intracranial hemorrhage was 25.4 years. All patients with a history of intracranial hemorrhage were classified as Rankin grade I or II at a mean follow-up interval of 6.0 years. A history of cerebral infarction or transient ischemic attack was found in 29.6% of patients with HHT and a pulmonary arteriovenous fistula. CONCLUSIONS: The risk of intracranial hemorrhage is low among people with HHT. Furthermore, a majority of these patients have a good functional outcome after hemorrhage. The data do not suggest a compelling indication for routine screening of patients with HHT for asymptomatic cerebral vascular malformations. By comparison, pulmonary arteriovenous fistulae are a much more frequent cause of neurological symptoms in this population.  (+info)

Identification of eight novel 5'-exons in cerebral capillary malformation gene-1 (CCM1) encoding KRIT1. (3/221)

Truncating mutations in the CCM1 gene encoding KRIT1 were recently found in patients affected by inherited cerebral capillary malformations, lesions that cause a wide variety of neurologic problems. However, CCM1 mutations have not been identified in all the families linked to CCM1. Here we demonstrate that the CCM1 gene contains eight additional exons which may thus encompass the missing mutations.  (+info)

Dural arteriovenous fistula in children: endovascular treatment and outcomes in seven cases. (4/221)

BACKGROUND AND PURPOSE: Dural AVF is a vascular anomaly that rarely occurs in children and is best treated by endovascular embolization. We report our experience using various endovascular embolization techniques in the treatment of dural AVF in a pediatric population. METHODS: Seven children with angiographically proven dural AVF were treated with endovascular embolization using microcoils, N-butylcyanoacrylate, detachable balloons, and/or silk suture. All imaging studies, embolization procedures, and patient charts were retrospectively reviewed. RESULTS: Seven children had been treated for dural AVF at our institution since 1987. Three newborns presented with congestive heart failure. Four older children (10 months-10 years) presented with signs referable to venous hypertension, including seizures, hydrocephalus, and proptosis. Embolization approaches included transarterial, transvenous, and direct puncture after neurosurgical exposure of a dural sinus. The number of embolizations ranged from 1 to 13 sessions per patient. All patients experienced symptomatic improvement after each embolization session. The three newborns showed marked improvement in cardiac function that allowed discharge to home. Clinical follow-up ranged from 3 weeks to 9 years (mean, 4.1 years). Two children with partially embolized dural AVF died, and one was lost to follow-up. Four children are alive after complete embolization of their dural AVF; two are developmentally normal, and two have mild developmental delay. CONCLUSION: Endovascular embolotherapy is the current treatment of choice for dural AVF. Embolization therapy may be life saving in the setting of cardiac failure and curative in cases of small or simple fistulae. Multiple, complex dural AVF are usually not curable, and treatment is aimed at symptomatic relief. Treatment strategies focus on the location and/or complexity of the fistula, the patient's clinical status, and the neurologic prognosis.  (+info)

Ultrastructural and immunocytochemical evidence that an incompetent blood-brain barrier is related to the pathophysiology of cavernous malformations. (5/221)

OBJECTIVES: Cerebral cavernous malformations are linked to mutations of the KRIT1 gene at the CCM1 locus and to mutations at two other loci, CCM2 and CCM3, for which genes are not yet identified. There is little information regarding the function of KRIT1. Histological and immunocytochemical analysis of cavernous malformations have not shed much light on their pathophysiology. METHODS: Morphological analysis of cavernous malformations was extended to the ultrastructural level by examining lesions from two patients by immunocytochemistry and electron microscopy. RESULTS: The lesions consisted of endothelial lined vascular sinusoids embedded in a collagen matrix. Nuclei belonging to cells distinct from endothelial cells were rare. The basal lamina of the endothelial cells consisted focally of multiple layers. No tight junctions at endothelial cell interfaces were found; however, several examined endothelial cell interfaces demonstrated apparent gaps between endothelial cell processes where basal lamina was exposed directly to the lumen of the sinusoids. Heavy hemosiderin deposits were found underlying the vascular channels within microns of the basal lamina without evidence of disrupted vessels. No astrocytic foot processes were seen within lesions. Glial fibrillary acidic protein immunocytochemistry confirmed that astrocyte processes stopped at the border of the lesions. CONCLUSIONS: The absence of blood-brain barrier components may lead to leakage of red blood cells into these lesions and the surrounding brain in the absence of major haemorrhage, thus accounting for the propensity of cavernous malformations to cause seizures. These data also raise the possibility that KRIT1 plays a part in the formation of endothelial cell junctions and expression of a mature vascular phenotype.  (+info)

MR imaging and histologic features of capillary telangiectasia of the basal ganglia. (6/221)

Capillary telangiectasias are being recognized with increasing frequency on MR imaging studies. Most are located in the brain stem and show slightly increased signal intensity on T2-weighted images, low signal intensity on T2*-weighted images (reflecting the presence of deoxyhemoglobin), and contrast enhancement. These findings are considered fairly typical for capillary telangiectasia, and pathologic correlation is not generally pursued. We present a case of a proven capillary telangiectasia in the basal ganglia. The imaging features of the lesion were identical to those described for capillary telangiectasias in the brain stem.  (+info)

Spinal dural arteriovenous fistulae--a diagnostic challenge. (7/221)

BACKGROUND: Spinal dural arteriovenous fistulae comprise the majority of spinal vascular malformations. The most common clinical presentation is that of progressive myeloradiculopathy, probably related to venous hypertension, which may lead to permanent disability and even death. OBJECTIVE: To report our clinical experience with spinal dural arteriovenous fistulae. METHODS: Nine patients with spinal dural AVF were managed at our center during a one year period (1998-1999). The patients, eight men and one woman ranging in age from 46 to 75 years, presented with initially fluctuating and eventually permanent and progressive paraparesis, sensory disturbances and sphincter dysfunction. The neurological signs generally began symmetrically and progressed from the distal to proximal limb regions. The duration of symptoms before diagnosis ranged from 6 to 36 months during which the patients underwent an extensive but fruitless work-up and even unnecessary operations due to misdiagnosis. All patients finally underwent magnetic resonance imaging and spinal angiography, which demonstrated the pathological vascular fistula. Interruption of the AVF was achieved by embolization or by surgical resection. RESULTS: Following treatment, six patients experienced improvement of gait and sphincter control, and the severe neurological deficits stabilized in the other three patients with long duration of illness. There was no further deterioration in any of the treated patients. CONCLUSIONS: The history, neurological findings and radiological changes on MRI scan should alert clinicians to the possibility of spinal dural AVF, leading to diagnostic spinal angiography. Early diagnosis and treatment may significantly improve outcome and prevent permanent disability and even mortality.  (+info)

Dural arteriovenous fistulae: noninvasive diagnosis with dynamic MR digital subtraction angiography. (8/221)

MR digital subtraction angiography (DSA) is a new diagnostic tool capable of producing dynamic images of the cerebral circulation with the injection of gadopentetate dimeglumine into a peripheral vein. Previous reports have concentrated on its potential as a noninvasive technique for the study of pial arteriovenous malformations. In this report, we present our early findings with MR DSA in the evaluation of intracranial dural arteriovenous fistulae.  (+info)

N2 - This article presents a modification to the existing classification scales of intracranial dural arteriovenous fistulas based on newly published research regarding the relationship of clinical symptoms and outcome. The 2 commonly used scales, the Borden-Shucart and Cognard scales, rely entirely on angiographic features for categorization. The most critical anatomical feature is the identification of cortical venous drainage (CVD; Borden-Shucart Types II and III and Cognard Types IIb, IIa + b, III, IV, and V), as this feature identifies lesions at high risk for future hemorrhage or ischemic neurological injury. Yet recent data has emerged indicating ...
BACKGROUND: Chronic pain due to spinal dural arteriovenous fistulae (SDAVF) during follow-up is a serious issue because it can affect patients quality of life. The severity of posttreatment chronic leg pain in patients with SDAVF is unclear. OBJECTIVE: To investigate the prevalence, severity, and characteristics of chronic leg pain in patients with SDAVF and to…
Spinal arteriovenous malformations are rare and still under-diagnosed entities. We present a case of a 59 year old man presented with paraparesis, lumbal MR imaging revealed high signal intensity within the spinal cord without contrast enhancement and flow voids along the dorsal surfaces of the cord at T6 to T11 level. Spinal angiography shows dural arteriovenous fistula at the level of T7 on the right side. The neurological and radiological findings completely resolved after endovascular treatment. The neurological symptoms due to venous congestion in the spinal dural arteriovenous fistula may be resolved if it is treated early and properly. Endovascular embolization is a safe and efficient way to treat. ...
OBJECT The authors report their preliminary experience using a balloon-assisted technique (BAT) in the transarterial embolization of intracranial dural arteriovenous fistulas (DAVFs). METHODS The authors reviewed the prospectively collected data obtained in 7 consecutive patients with DAVFs in whom embolization was achieved using transarterially injected Onyx with either the venous or arterial BAT. Procedures were performed at the Division of Interventional Neuroradiology at the University of California at Los Angeles Medical Center between September 2005 and January 2008. RESULTS Three patients presented with cortical venous reflux and 4 did not. Three patients underwent transarterial Onyx-based embolization combined with transvenous balloon protection; the balloon was inflated in the transverse sinus in 2 of these patients and in the superior sagittal sinus in the third. One of them underwent an additional transarterial Onyx embolization with arterial BAT, whereas 4 other patients were treated
BACKGROUND: Dural arteriovenous fistulas are intracranial vascular malformations, fed by dural ar...teries and draining venous sinuses or meningeal veins. Clinical course varies widely and ranges from benign with spontaneous remission to fatal, due to cerebral hemorrhage. In a 10-year single institution experience, clinical presentation of dural arteriovenous fistulas, and in particular headache and angiographic features, as well as long-term outcome were analyzed. METHODS: Data of 42 intracranial dural arteriovenous fistulas of 40 patients concerning demographic characteristics, medical history and risk factors, clinical presentation and headache features, location and neuroimaging findings, as well as treatment and outcome, were collected. Furthermore, we used the modified-Rankin Scale to assess the long-term outcome, by telephone contact with patients and/or their relatives. RESULTS: Patients aged between 25 and 89 years (mean age 55.8 ± 15.5). According to different clinical presentation ...
Evolution after treatment. The clinical response was favorable, with gradual improvement of motor deficit, regaining the ability to walk soon after hospital discharge. Two months later, the patient got significant improvement. The patient continued with rehabilitation and he had an almost complete recovery. One year after treatment, control arteriography was performed showing persistent occlusion of the DAVF.. Discussion. It is believed that spinal DAVFs (SDAVFs) are an acquired pathology, although its exact etiology is unknown. Arteriovenous communication occurs between a dural branch of the radicular artery, with the nest of vessels located in the dura near the radicular exit, and a vein, which drains intradurally into the venous perimedullary plexus.2,3 Dural arteriovenous fistulas (DAVFs) at the craniocervical junction are uncommon but they produce clinical important abnormalities. These lesions have two main forms of clinical presentation; acute subarachnoid hemorrhage (SAH) and ...

N2 - Intracranial dural arteriovenous fistulas (dAVFs) are pathologic dural-based shunts and distinguished from parenchymal AVM by the presence of a dural arterial supply and the absence of a parenchymal nidus. Their symptoms and prognosis are strongly related to the pattern of their venous drainage system. The presence of cortical venous reflux (CVR) is an aggressive feature indicating that there is a high risk of cerebral bleeding or progressive neurological deficits. Endovascular treatment has become the mainstream dAVF therapy. In general, trans-venous coil embolization is adapted to sinusal type dAVFs (i.e. ...

Background and aim 9 patients with 10 arteriovenous fistulas were treated with Onyx at our institution over a period of 19 months 4 direct and indirect carotid-cavernous fistulas (CCFs) and 6 dural arteriovenous fistula (DAVFs). Complete occlusion was achieved with no recurrences or permanent complications in our small series. We report hemodynamic instability, including severe bradycardia and asystole, during embolization of DAVF and CCF with Onyx in several patients. These changes were reversible with interruption of Onyx injection and administration of atropine. No recurrence of symptoms after atropine administration was noted as Onyx embolization continued during the same session or during postprocedural 24 h monitoring. No adverse clinical consequences were noted.. Results Bradycardia was observed in four cases, with a brief asystole in two of these patients during transarterial and transvenous Onyx delivery at cavernous sinus and orbital levels. Based on our observation, hemodynamic ...

Cranial dural arteriovenous fistulae have been classified into high- and low-risk lesions mainly based on the pattern of venous drainage. Those with leptomeningeal venous drainage carry a higher risk of an aggressive clinical presentation. Recently, it has been proposed that the clinical presentation should be considered as an additional independent factor determining the clinical course of these lesions. However, dural shunts with leptomeningeal venous drainage include a very wide spectrum of inhomogeneous lesions. In the current study, we correlated the clinical presentation of 107 consecutive patients harboring cranial dural arteriovenous shunts with leptomeningeal venous drainage, with their distinct anatomic and angiographic features categorized into eight groups based on the DES (Directness and Exclusivity of leptomeningeal venous drainage and features of venous Strain) concept. We found that among these groups, there are significant angioarchitectural differences, which are reflected by ...
A dural arteriovenous fistula (DAVF), is an abnormal direct connection (fistula) between a meningeal artery and a meningeal vein or dural venous sinus. In cases where there are multiple fistulas, the related term dural arteriovenous malformation (DAVF) is used. The most common signs/symptoms of DAVFs are: Pulsatile tinnitus Occipital bruit Headache Visual impairment Papilledema Pulsatile tinnitus is the most common symptom in patients, and it is associated with transverse-sigmoid sinus DAVFs. Carotid-cavernous DAVFs, on the other hand, are more closely associated with pulsatile exophthalmos. DAVFs may also be asymptomatic (e.g. cavernous sinus DAVFs). Most commonly found adjacent to dural sinuses in the following locations: Transverse (lateral) sinus, left-sided slightly more common than right Intratentorial From the posterior cavernous sinus, usually draining to the transverse or sigmoid sinuses Vertebral artery (posterior meningeal branch) It is still unclear whether DAVFs are congenital or ...
We report the angiographic findings from six patients with intracranial dural arteriovenous fistulas of the inferior petrosal sinus and describe the clinical presentation, vascular anatomy, and embolization techniques used in the treatment of this disorder. Dural arteriovenous fistulas at this site are rare; of 105 patients diagnosed with this abnormality, only six had lesions involving the inferior petrosal sinus. The patients included three men and three women, ranging in age from 41 to 75 years. Patients presented with bruit, proptosis, abducens palsy, or loss of vision, and symptoms were present for up to 1 year prior to diagnosis. These presentations were similar to cavernous sinus arteriovenous fistulas. The arterial supply in all cases was from branches of the external carotid artery and in three cases from the meningohypophyseal trunk of the internal carotid artery. Venous drainage in four patients was via the cavernous sinus to the superior ophthalmic vein. The remaining two patients ...

The potential for functional ambulation in patients with SDAVF is related to the time of intervention. This finding emphasizes the important of early diagnosis and early intervention in SDAVF.
Mironov3 first described 2 cases of selective transvenous embolization of DAVFs, including 1 superior sagittal sinus DAVF and 1 TSS-DAVF. Since then, several cases of intracranial DAVF shunting to a localized venous pouch adjacent to the major dural sinuses have been reported, which can be treated by selective transvenous embolization while preserving the sinus drainage from normal cerebral veins. These are generally thought to be special cases of intracranial DAVF.4 Of 140 cases of TSS-DAVFs, Caragine et al5 described 10 patients with TSS-DAVFs with a fistulous venous channel in a position parallel to the TSS (parallel venous channel). However, we often observed similar parasinusal venous pouches in many cases of intracranial DAVFs in our clinical practice. Piske et al6 investigated cerebral angiography in 40 intracranial DAVFs and found a dural sinus compartment in 12 of the 40 cases (30%). Nine of these cases could be treated by a selective transvenous embolization technique, preserving the ...

Dural arteriovenous fistulas (DAVFs) in the craniocervical junction are rare but clinically important. DAVFs can be associated with subarachnoid hemorrhage (SAH), a feature distinguishing them from DAVFs in the thoracolumbar region. These lesions are often overlooked at cerebral angiography performed to assess SAH and account for a small proportion of angiographically negative SAHs. After managing two cases of cervical spinal DAVF manifesting as SAH, we analyzed all cases in the literature to identify features associated with bleeding at presentation.
Diagnostic procedure of choice: Angiography is the most important DAVF diagnosis tool. This study shows the connection, generally from the extracranial circulation, with venous sinuses and/or subarachnoid veins. Intracranial branches might also be involved, although less frequently. It is essential to rule out the presence of cortical venous reflux and intracranial varices, which correlate with the risk of clinical manifestation. ...

Over the past decade substantial advances in diagnostic imaging, classification, and understanding the natural history of intracranial dural arteriovenous fistula (dAVF) have been made. Paralleling these improvements in patient evaluation and risk assessment have been considerable innovations and refinements in the microsurgical and endovascular techniques by which appropriately selected patients with dAVF are treated. On the microsurgical front, minimally invasive surgical approaches with less soft tissue and bony disruption, along with enhanced tools for the intraoperative assessment of vascular anatomy and completeness of dAVF obliteration, are now commonly utilized. On the endovascular front, liquid embolic agents, balloons, and flow-directed catheters have transformed our capacity to safely and effectively treat dAVFs with a variety of anatomic configurations and locations. Innovative combinations of microsurgical and endovascular approaches are even being applied to select cases. In this ...

Background: Concomitant dural arteriovenous fistulas (DAVFs) and meningiomas have been rarely described. DAVFs can be either continuous or at a distant location from the meningioma, with different pathophysiologic mechanisms involved in each situation.. Case Description: We report the case of a 74-year-old woman presenting with left-sided hemiparesis secondary to a large right convexity meningioma, associated with a noncontiguous Borden 3 DAVF. Both lesions were treated surgically in the same setting. The patient improved after surgery, and postoperative imaging showed complete resection of the meningioma and absence of recurrence of the fistula at 4 years.. Conclusion: To the best of our knowledge, this is the first case of concomitant surgical treatment of a meningioma and noncontiguous DAVF.. Keywords: Dural arteriovenous fistula, DAVF, Meningioma, Vascular malformations. ...
A 66-year-old woman presented with intermittent paraparesis and generalized tonic-clonic seizure. Cerebral angiography demonstrated dural arteriovenous fistula (AVF) involving superior sagittal sinus (SSS), which was associated with SSS occlusion on the posterior one third. The dural AVF was fed by bilateral middle meningeal arteries (MMAs), superficial temporal arteries (STAs) and occipital arteries with marked retrograde cortical venous reflux. Transfemoral arterial Onyx embolization was performed through right MMA and STA, but it was not successful, which resulted in partial obliteration of dural AVF because of tortuous MMA preventing the microcatheter from reaching the fistula closely enough. Second procedure was performed through left MMA accessed by direct MMA puncture following small decortications of cranium overlying the MMA using diamond drill one week later. Microcatheter could be located far distally to the fistula through 5 F sheath placed into the MMA and complete obliteration of ...

Background: Although almost all dural arteriovenous fistulas (DAVFs) can be highly curable using endovascular treatment, some of them are reflactory. We evaluated the efficacy of stereotactic radiosurgery for DAVFs reflactory to endovascular treatment.. Methods: In 178 patients with DAVFs treated by endovascular embolization in our institution, 12 patients were reflactory and treated by CyberKnife (CK) radiosurgery. Patients background, efficacy of CyberKnife radiosurgery and complication were analyzed.. Results: 5 men and 7 women underwent CyberKnife radiosurgery. Ages ranged from 21 to 74 years (mean, 57.5 years). The locations of the fistulas were 10 transverse/sigmoid sinus and 2 cavernous sinus. The Borden classification was I in 3, II in 6, and III in 3 patients. Transarterial embolization (TAE) was performed in 10 patients, TAE and transvenous embolization (TVE) in 2. In all cases, shunt flow could be reduced, but small flow was residual. After embolization, residual fistula was treated ...
Capital Medical University, Beijing Neurosurgical Institute and Beijing Tiantan Hospital, Beijing, China DOI : 10.5137/1019-5149.JTN.8412-13.2 AIM: Most dural arteriovenous fistulas (DAVFs) can be treated safely and effectively with endovascular Onyx embolization.

A 28-year-old woman had a normal delivery (primipara) on January 15, 2009. On March 20, 2009, she suffered sudden onset of severe headache. Protein-S and protein-C levels were within the normal ranges. Computed tomography on admission showed no subarachnoid hemorrhage, and the patient was discharge with analgesic treatment. Four days later the patient presented again to our emergency department with increased headache, nauseas, vomiting and bruit of the head. In view of the history and clinical evolution, an urgent computerized tomography (CT) brain scan with intravenous contrast was done showing the empty delta sign; as magnetic resonance imaging (MRI) scan was not available at that time, computed tomography in venograms (Fig. 1a,b) was performed revealing occlusion of the superior sagittal sinus and the bilateral transverse sinus. The patient was referred to the Department of Neurosurgery where a cerebral angiography confirmed sinus thrombosis (ST) and revealed a dural arteriovenous fistula ...
Intracranial multiple dural arteriovenous fistulas (MDAVFs) are rare lesions that are difficult to treat. The key factors involved in the development of MDAVFs remain unknown. At present, the majority of reports on intracranial MDAVFs are confined to case reports and small case series, and thus understanding of MDAVFs is limited. The current review assesses the available literature to date with the aim of reviewing the progress in research on intracranial MDAVFs. Intracranial MDAVFs may be divided into two types: Synchronous and metachronous. While the exact pathogenesis of MDAVFs is unknown, a number of possible mechanisms are considered relevant. The first is that MDAVFs develop following recanalization of a large sinus thrombosis that involves several sinuses. The second possibility is that a pre-existing DAVF may induce sinus thrombosis or venous hypertension, resulting in a new MDAVF. The third is that MDAVFs are caused by increased angiogenic activity, which may induce the development of ...

TY - JOUR. T1 - Giant arachnoid granulation with a thrombosed dural arteriovenous fistula. AU - Karegowda, Lakshmikanth Halegubbi. AU - Rajagopal, Kadavigere. AU - Krishnamurthy, Suresh Kanase. AU - Lakshmana, Shivarajkumar. PY - 2018/1/1. Y1 - 2018/1/1. N2 - Arachnoid granulations are common incidentally detected small dural lesions which are usually asymptomatic and follow cerebrospinal fluid density/signal intensity on CT/MRI. Such lesions reaching a size of more than 1 cm are termed as giant arachnoid granulations (GAGs) which have been previously reported to cause venous hypertension and headaches. We report a case of GAG involving the proximal half of the superior sagittal sinus in a 45-year-old male patient which was associated with left temporal thrombosed dural arteriovenous fistula (AVF) whose thrombosed draining veins were seen converging towards the site of GAG. The patient presented with three episodes of generalised tonic-clonic seizures and improved with conservative treatment. No ...

TY - JOUR. T1 - Interaction between krit1 and malcavernin. T2 - Implications for the pathogenesis of cerebral cavernous malformations. AU - Zhang, Jun. AU - Rigamonti, Daniele. AU - Dietz, Harry C.. AU - Clatterbuck, Richard E.. PY - 2007/2/1. Y1 - 2007/2/1. N2 - OBJECTIVE: Cerebral cavernous malformations (CCM) are a relatively common autosomal dominant disorder leading to the formation of vascular malformations in the nervous system. Mutations in krit1 and malcavernin, the proteins encoded by the genes at the CCM1 and CCM2 loci, respectively, are responsible for the majority of CCMs. Similar to integrin cytoplasmic domain-associated protein-1α, a known krit1 interactor, malcavernin is a phosphotyrosine binding protein. We report here that krit1 also interacts with malcavernin. METHODS: We used two-hybrid analysis, in vivo coimmunoprecipitation, and epitope mapping to explore the interaction between krit1 and malcavernin. Immunocytochemistry was used to study the cellular localization of these ...

Conebeam CT (CBCT) is an imaging technique that employs a divergent x-ray source and usually a large-area flat-panel detector to form a cone-shaped exposure to the imaged object. Such a configuration guarantees the volume coverage of one large object and achieves the volumetric imaging within one single scan. The first CBCT scanner entered the market in 1996 as the dental scanner by NewTom Corp. Subsequently, CBCT was extended to multiple clinical applications, including implantology, orthopedics, interventional radiology, and radiation oncology.
