Dural AVF classification

Borden classification of dural arteriovenous fistulas

  1. The Borden classification of dural arteriovenous fistulas (DAVF) groups these lesions into three types based upon the site of venous drainage and the presence or absence of cortical venous drainage. It was first proposed in 1995 1
  2. The Cognard classification 13 is based on the direction of dural sinus drainage, the presence or absence of CVD, and venous outflow architecture (nonectatic cortical veins, ectasia cortical veins, or spinal perimedullary veins). Type I lesions drain into the dural sinus, have an antegrade flow direction, and lack CVD
  3. Classification of dural AVF's is important because this indicates a patient's risk of bleeding from the fistula and the consequences that may occur from a bleed. Under the Borden classification system dural AVF's are classified into 3 areas: Fistula where the venous drainage goes directly into the dural venous sinus or meningeal vein

Intracranial Dural Arteriovenous Fistulas: Classification

  1. AMINOFF (2) proposed a classification of dural AV fistula (DAVF) into 2 groups according to the topography of the dural sinuses: an anterior-in- ferior group and a superior-posterior group
  2. ation of the risk with each dural AVF and enables decision-making about the appropriate therapy
  3. RESULTS: Type I dural AVFs had a benign course. In type II, reflux into the sinus induced intracranial hypertension in 20% of cases, and reflux into cortical veins induced hemorrhage in 10%. Hemorrhage was present in 40% of cases of type III dural AVFs and 65% of type IV. Type V produced progressive myelopathy in 50% of cases
  4. Intracranial dural arteriovenous fistulae (dAVFs) are typified by pathological anastomoses between meningeal arteries and dural venous sinuses or cortical veins
  5. Dural arteriovenous fistulas (dAVF) are vascular abnormalities in which arteries arising from branches of the carotid or vertebral arteries drain directly into the dural leaflets of the venous sinuses. They are sometimes referred to as dural arteriovenous malformations. Their location is more commonly supratentorial than infratentorial

Cognard classification Type V of Dural Arteriovenous Fistula (dAVF), is a rare subtype of cranial dAVF, characterized by congestion of the perimedullary venous system with drainage into a spinal vein. Dysfunction of the medulla and spinal cord caused by venous hypertension is the most probable cause of the neurological symptoms in such cases 1) accurate method for complete characterization and classification of DAVFs. The pattern of venous drainage observed on dynamic vascular imaging determines the type of DAVF and correlates with the severity of symptoms and the risk of hemorrhage. ABBREVIATIONS: CVD cortical venous drainage; DAVF dural arteriovenous fistula; DMS Although there have been many classification schemes sug-gested for DAVF, the 2 proposed by Borden and Cognard are the most widely used. 1 The Borden classification system ( Table 1) cat-egorizes DAVF based on the site of venous drainage (dural sinus versus cortical vein) and the absence or the presence of CVD.3

There are 2 widely used angiographic classification systems for DAVFs: the Borden-Shucart 3 and Cognard 10 classifications (Table 1). In the Borden-Shucart system, classifications are based on the site of venous drainage (dural sinus and/or cortical vein) and the presence or absence of CVD A dural arteriovenous fistula (DAVF) or Malformation, is an abnormal direct connection (fistula) between a meningeal artery and a meningeal vein or dural venous sinus Borden and Cognard are amongst the more widely used.

Classification of Spontaneous Dural Arteriovenous Fistulas

  1. ✓ A number of classification schemes for intracranial dural arteriovenous fistulas (AVFs) have been published that claim to predict which lesions will present in a benign or aggressive fashion based on radiological anatomy. We have tested the validity of two proposed classification schemes for the first time in a large single-institution study
  2. ance (80-90%) and generally present in late adulthood, ages 40-60. Presentation is generally with radiculomyelopathy, followed by slow but progressive neurologica
  3. Dural arteriovenous malformations represent 10 to 15% of intracranial vascular malformations. They are characterized by the presence of an abnormal arteriovenous fistula or nidus located in the dura. Common nidus locations include the transverse, sigmoid, and cavernous sinuses as well as the falx and floor of the frontal fossa
  4. Dural AVFs were supplied by a radicular branch along the dural nerve root sleeve that drained via an AVF into the coronal venous plexus. This classification system included no description of extradural-intradural or conus AVMs
  5. Although several classification systems have been developed to grade the risks of dural AVFs, those devised by Cognard et al (,3) and Borden et al (,8) are the most widely used (,Tables 23). Dural AVFs that drain via the retrograde leptomeningeal cortical venous drainage channel show a significantly high rate of aggressive symptoms
  6. Dural arteriovenous fistulas (dAVF), also referred to as dural arteriovenous malformations (AVM), are abnormal shunts between the arterial and venous systems located within the dura. The aetiology of the dAVF is unclear in many instances; however, they are thought to be acquired after trauma, surgery, venous stenosis or sinus thrombosis

Intracranial dural arteriovenous fistulas (dAVFs) are a group of acquired pathological vascular malformations that are defined by an abnormal connection between an artery and a vein, bypassing the capillary bed. The shunting that is confined to the dura is supplied. These findings could be (and were) interpreted as being from a dural arteriovenous fistula from the inferolateral trunk arising from the internal carotid artery. In fact, these findings are due to retrograde flow up the left internal jugular vein (reflux) 1 . A few clues indicate that this is the case, in addition to it being increasingly.

sequently incorporated into a classification scheme for transverse sinus intracranial dural AVF by Lalwani and coworkers.11In 1986, Lasjaunias and associates13 demon-strated that venous drainage characteristics determined the type of symptoms that were manifested and that focal neu-rological deficits were a function of the territory of venous. The original Djindjian dural arteriovenous fistula (dAVF) classification has largely withstood the test of time as a meaningful descriptive and predictive grading scheme. Cerebral dural arteriovenous fistulas (dAVFs) lacking cortical venous reflux (Type I) may present with flow symptoms (tinnitus) or symptoms secondary to ocular venous. Spinal vascular malformations have several classification systems. SDAVFs are classified in two major categories. Lesions primarily associated with the nerve root are called radicular dural AVFs, and lesions primarily in the subarachnoid space are called perimedullary dural AVFs.Arteriovenous lesions that are located in the spinal cord—that is, involving the spinal pia and extending into the. Hemorrhage was present in 40% of cases of type III dural AVFs and 65% of type IV. Type V produced progressive myelopathy in 50% of cases. Conclusion This classification provides useful data for determination of the risk with each dural AVF and enables decision-making about the appropriate therapy

Dural Arteriovenous Fistul

Dural arteriovenous fistulas (DAVFs) (see figure) are defined as direct shunts between arteries and venous sinuses or cortical veins with no transitional capillary network contained within the leaflets of the dura mater, the thick layer of the meninges that covers the brain. They are supplied by branches of the carotid and vertebral arteries before they penetrate the dura Table 3 Borden classification of dural arteriovenous fistula 25. Full size table. Figure 3. Representative brain MRI images and TFCA findings of (A) transverse-sigmoid sinus dAVF,. The Borden and Cognard classifications in general prove useful in allowing prediction of risk of rupture of any given dural arteriovenous fistula based on dural venous drainage patterns and presence or absence of cortical venous reflux and venous abnormalities. However, the prediction is coarse and does not take into account lesion location Dural Arteriovenous Fistula • Classification based on location of shunt (dural or direct cortical vein) and presence or absence of cortical venous drainage (CVD) -Low grade fistulas, no CVD (Borden type I, Cognard type I or IIa) •Usually benign, low risk of IC Transverse and Sigmoid Dural Arteriovenous Fistula Johnny Wong, Rachel Tymianski, Vitor Mendes Pereira, Ivan Radovanovic, and Michael Tymianski Abstract Dural arteriovenous fistulae (DAVFs) are arteriovenous shunts located within the dural leaflets and constitute 10 to 15 % of intracranial vascular malformations.

Multiple classification systems have been proposed to attempt to describe these lesions. We describe the case of a patient with a dorsal epidural DAVF that, while cerebral in origin, presented with classic spinal DAVF symptoms. Following embolisation, the patient had complete radiographic and symptomatic resolution [1, 2] This allowed more systematic classification and management with less confusion in diagnosis of these often complex lesions. The ISSVA classification of vascular anomalies has subsequently been modified and refined. Arteriovenous fistula (AVF), by definition, describes an abnormal communication between an artery and a vein Dural arteriovenous fistulas (DAVF) are a heterogeneous collection of conditions that share arteriovenous shunts from dural vessels. Atherosclerosis, aneurysms or dissection of the internal carotid artery, cerebral sinus thrombosis, and some other rare pathologies are among the vascular causes of pulsatile tinnitus [ 1 ]

Dural arteriovenous fistulas (DAVF) are abnormal communications between arterial and venous circulation that may arise either spontaneously or as a result of trauma [].DAVFs account for 15% of all cerebrovascular malformations [].Previous studies have determined DAVFs occur in both sexes equally and the onset of symptoms most commonly occurs between the third and sixth decade of life [] 21.

A dural arteriovenous fistula (AVF) is an arteriovenous shunt in the dura and is associated with a risk of intracranial hemorrhage and neurologic deficit. The morbidity of this disease depends on venous hypertension, and the classification of this disease is based on the pattern of venous drainage Spinal dural arteriovenous fistulas (SDAVFs) are abnormal connections between radicular arteries and venous plexus of the spinal cord. SDAVFs most commonly present with pain and weakness in the lower limbs (which presents as difficulty in climbing stairs, gait disturbances)and sphincter dysfunction that is gradually progressive Dural AV Fistula. Findings: Sagittal T2 weighted images of the thoracolumbar spine show diffuse abnormal hyperintense intramedullary signal, associated with a few serpentine low voids along the dorsal surface of the spinal cord. Spinal angiography shows abnormally enlarged draining veins at the level of L1, associated with a small nidus of vessels Classification is based on arteriography. Current classifications of dural arteriovenous fistula (Borden classification and Cognard classification) are based on the drainage pattern, the dynamics of the lesion and the presence of morphological alterations associated. Fig. 1. Natural History Dural arteriovenous fistulas (DAVFs) represent 10-15% of intracranial arteriovenous malformations. Of these, only 12-29% cause intracranial hemorrhage. The presentation of DAVF as a subdural hematoma (SDH) and intraparenchymal hemorrhage (IPH) is infrequent; additionally, behavioral changes are not common among these patients. We report, for the first time in our country, the case of a 23.
