Meyers PM, Halbach VV, Dowd CF, Lempert TE, Malek AM, Phatouros CC et al. Similar to embolization of direct CCFs, embolization of dural CCFs may be accomplished using coils, acrylic glue, or Onyx, which can be used individually or in combination.54, 55 Flow-diverting stents also may be used alone or in combination with coils.20 Advantages of coils include their radio-opacity and ability to be re-deployed or removed if initial placement is not ideal; however, their solid, fixed state may lead to compartmentalization within the cavernous sinus, thus producing incomplete embolization of the fistula.

CCFs may be classified into four types: direct fistulas (Barrow type A) and dural, or indirect, fistulas (Barrow types B, C, and D).1 Direct fistulas are characterized by a direct connection between the internal carotid artery (ICA) and the cavernous sinus (Figure 1a).1 They are usually high-flow fistulas. Case report. Neurosurgery 1996; 39 (4): 853–855. Left eye conjunctival and episcleral injection in a patient with a left-sided CCF. As up to 70% of dural CCFs close spontaneously due to local thrombosis of the SOV propagating posteriorly, observation or conservative treatment techniques not only are acceptable but also are the preferred approaches to management in cases without high-risk features.20, 33, 37, 51 Initially, spontaneous closure may be associated with exacerbation of the clinical symptoms and signs; in this setting, patients may require repeat angiography.34 Closure of dural CCFs also has been reported after diagnostic angiography and air travel.17, 37, 49 If invasive intervention is not warranted, patients may use techniques of occlusion, such as external manual carotid compression, to promote resolution of the CCF.

[3] Carotid-cavernous fistula following nasopharyngeal biopsy. Carotid-cavernous fistulas (CCFs) are abnormal communications between the CS and ICA or between CS and dural branches of ICA and/or ECA. In addition, enlargement of the SOV on standard CT scanning or MR imaging (MRI), either unilaterally or bilaterally, has been found to be suggestive of a CCF (Figure 8).28 CT and MRI also may show orbital congestion, with enlargement of the extraocular muscles and periorbital fat, and convexity of the lateral wall of the cavernous sinus.34 However, as these findings are not specific for a CCF, patients in whom a CCF is suspected still may require DSA, which remains the gold standard for classification and diagnosis of CCF and can be both diagnostic and therapeutic. Check for errors and try again. Similarly, although most clinics do not have access to a pneumotonograph, pneumotonometry can be a valuable diagnostic tool, as a difference in ocular pulse amplitudes (defined as the difference between systolic and diastolic IOP) of 1.6 mm Hg between the two eyes has been shown to be 100% sensitive and 93% specific for a CCF (Figure 7).34 Orbital ultrasound typically reveals a dilated superior ophthalmic vein (SOV) and evidence of orbital congestion with enlarged extraocular muscles and also can be used to exclude mimickers of CCF, including orbital tumours, dysthyroid orbitopathy, orbital inflammation, and scleritis.37 Colour Doppler evaluates flow velocity and direction, thus indicating arterial flow in the orbital veins in cases of CCF.33 The presence of flow reversal in the SOV is suggestive of a CCF. Venous microcatheter injections into the cavernous sinus confirm the caroticocavernous fistula anatomy visualized by right internal carotid artery injections, with eventual microcatheter position wedged into venous side of caroticocavernous fistula. MR/MRA findings are similar with the addition of orbital oedema and abnormal flow voids in the affected cavernous sinus.

Of those patients, 314 met criteria for massive hemoptysis and treatment was attempted using embolization in 287 (91.4%). As dural CCFs often resolve spontaneously, low-risk cases may be managed conservatively. [14] The left was then subsequently embolized.

Both techniques have high sensitivities for both direct and dural CCFs that cause visual manifestations. When invasive treatment is warranted, endovascular intervention or stereotactic radiosurgery may be performed. [10] J Clin Med Res 2016; 8 (4): 342–345. Carotid cavernous fistulas (CCFs) are abnormal connections between the carotid artery and the cavernous sinus. The pain was associated with left exophthalmos and red-eye without loss of vision. Minor transient complications, including haematoma, facial pain, and ocular motor nerve palsies, occur in 1–30% of cases.18 Major sequelae, including hemiparesis and permanent ocular motor nerve palsy, are quite rare in the general population; however, patients with Ehlers–Danlos type IV have much higher complication rates with both diagnostic and therapeutic endovascular procedures due to the underlying vascular fragility in this condition.4 In addition, some authors report often-overlooked, moderate, persistent ocular motor deficits, which they relate to coil volume, either indirectly, as a surrogate marker for the size of the initial vascular injury, or directly, via associated mass effect on the cranial nerves within the cavernous sinus.50, Treatment options for dural CCFs include observation, IOP-lowering agents, intermittent compression of the ipsilateral ICA or SOV, stereotactic radiosurgery, and endovascular intervention. Using the contralateral hand, the patient compresses the ICA on the involved side, thus lowering the carotid arterial pressure through the fistula. J Neurosurg Case Lessons. As arterial blood under high pressure enters the cavernous sinus, the normal venous return to the cavernous sinus is impeded and this causes engorgement of the draining veins, manifesting most dramatically as a sudden engorgement and redness of the eye of the same side.

J Neurosurg 2011; 114: 129–132. Although the majority of patients with a CCF have dilation of the SOV, an SOV that is fragile, small, thrombosed, or associated with other vascular anomalies (eg, varices) may elude cannulation.62 Nonetheless, success of this approach has been reported even in the setting of SOV thrombosis.54 When transvenous approaches are not feasible due to vessel tortuosity, or venous sinus thrombosis or occlusion, a direct orbital approach to the cavernous sinus with fluoroscopic guidance may be considered.58 A recent systematic review reported a 90% success rate with no major complications among CCF embolization procedures completed via an orbital approach.63 Coils commonly are used in transvenous procedures (Figure 10). 12, Generalmente se originan de la pared lateral de la dura aunque también pueden ser exclusivamente intracavernosos.La cola dural es la característica más típica de estos tumorse.Captan contraste de forma intensa pueden crecer hacia la cisterna prepontina y comprimen la carótida interna . 2022 Jun 20;3(25):CASE22115.

Invasive treatment usually is not required in most cases of low-flow fistulas, as these may close spontaneously. Lessons learned from difficult or unsuccessful cannulations of the superior ophthalmic vein in the treatment of cavernous sinus dural fistulas. Previously, the treatment options for direct CCFs were limited to observation or treatment consisting of trapping of the fistula by ligating the cervical ICA proximal to the fistula and the intracranial ICA distal to the fistula or occlusion of the common carotid artery or ICA, either of which could result in a cerebral ischaemic event due to an induced low-flow state or an embolic event.1, 40 With the development of endovascular interventional techniques, open surgical procedures are no longer preferred, the range of potential therapies has broadened, and the ICA almost always can be preserved.

Se extiende desde el ápex orbitario y la fisura orbitaria superior  a nivel anterior y  hasta el cavum de Meckel  y la dura a nivel posterior. In indirect CCFs, the transvenous route is preferred as it shows better outcomes [16]. Reports of complete resolution of a CCF with SRS treatment range from 50 to 100%.36, 70, 71 The risk of immediate complications is low; however, data on late radiation-induced complications are limited.36. 5. Miller NR . In addition, there were enlarged extraocular muscles on the left side, as evidenced by axial and cornonal MRI (E, F). The success rate for transvenous procedures is ~80%, albeit with a centre-dependent complication rate that ranges up to 20%.19, 31, 61, 65, 66 Reported complications include ocular motor nerve palsies; trigeminal sensory neuropathy; brainstem infarction; significant IOP elevation; intracranial haemorrhage; pulmonary emboli; and orbital haemorrhage in the setting of the SOV or inferior ophthalmic vein approach.61, 65, 66, 67, 68 In addition, a case of inappropriate antidiuretic hormone secretion (SIADH) has been reported, which the authors attributed to disruption of posterior pituitary blood supply by the Onyx used for embolization.69 Although the risk involved necessitates careful patient selection, successful endovascular treatment can lead to marked improvement in signs and symptoms (Figure 11). The endovascular management of these lesions is currently possible with excellent results.

Color Doppler imaging shows characteristic SOV findings (dilatation, increased velocity, arterial pulsation and reversal of blood flow direction), suggesting that Doppler can help not only in the diagnosis but also in the follow-up of patients with CCFs [13,14]. Br J Neurosurg 1999; 13 (2): 185–188. Prior to treatment, the common carotid arteriogram shows a dural CCF draining both anteriorly and posteriorly (left). In direct fistulas there is an abnormal communication between the internal carotid artery and the cavernous sinus. Use the Previous and Next buttons to navigate three slides at a time, or the slide dot buttons at the end to jump three slides at a time. Evaluation of a suspected CCF often involves non-invasive imaging techniques, including standard tonometry, pneumotonometry, ultrasound, computed tomographic scanning and angiography, and/or magnetic resonance imaging and angiography, but the gold standard for classification and diagnosis remains digital subtraction angiography.

Estas venas en la parte posterior del ojo transportan sangre desde la cara y el cerebro de regreso al corazón y están ubicadas en pequeños espacios detrás de los ojos llamados senos cavernosos. The dural fistulas usually have low rates of arterial blood flow and may be difficult to diagnose without angiography.

According to Thomas classification, CCFs with posterior/inferior drainage only, posterior/inferior and anterior drainage, anterior drainage only, and retrograde drainage into cortical veins with/without other drainage channels were designated as types 1, 2, 3, and 4, respectively. [8] The most common cause of hemoptysis was bronchiectasis (n=99, 31.5%), followed by lesions due to tuberculosis (n=57, 18.1%) and chronic bronchitis (n=47, 14.9%).Angiography of the bronchial arteries provided evidence to account for the hemoptysis in 287 patients (91.4%). The latter is considered the mainstay therapy for definitive treatment of CCFs [2]. Please enable it to take advantage of the complete set of features!

However, with the use of Onyx, success of the transarterial approach in treating dural CCFs has increased, with one paper reporting angiographic cure rates of 87% when the agent is used alone and 79% when it is used in combination with another agent, with a 2% risk of permanent complications.59, Despite increasing success of transarterial procedures, a transvenous approach via the IPS, superior petrosal sinus, basilar plexus, pterygoid plexus, SOV, or inferior ophthalmic vein, still is preferred for most dural CCFs that require treatment (Figure 10).41, 58, 60 The IPS is the first-line approach, as it is the most straightforward and shortest route to the cavernous sinus. Differences in performance among the methods depended primarily on the segmental location of the fistula along the ICA.
