Endovascular arterial occlusion accomplished using microcoils deployed with and without proximal flow arrest: results in 19 patients. (1/104)

BACKGROUND AND PURPOSE: Prior to their relatively recent FDA approval, detachable balloons for endovascular arterial occlusion had been available on only a limited basis. We evaluated the feasibility of permanent endovascular carotid and vertebral artery occlusion using microcoils deployed with and without proximal flow arrest in 19 patients. METHODS: Permanent endovascular occlusion was performed in 19 arteries of 19 patients. The treated lesions included nine aneurysms, one carotid-cavernous fistula/pseudoaneurysm, seven neoplasms, and two dissections. Nondetachable balloons were used to arrest proximal blood flow during occlusion of only six arteries. Anticoagulation (heparin, 5000 U IV) was used during occlusion of 18 arteries. Three to 88 coils were used per lesion. Complex fibered platinum microcoils were used for all cases, and GDCs were also used in two patients. RESULTS: Sixteen patients had no new neurologic deficits after arterial occlusion. No patient had an acute event that suggested an embolic complication. Coils provided rapid and durable arterial occlusion in 17 patients. In both patients with acute carotid artery rupture, large numbers of coils placed during flow arrest failed to produce complete occlusion, which was accomplished subsequently with detachable balloons. One of these patients incurred a fatal hemispheric infarct after occlusion. One patient treated for a ruptured posterior inferior cerebellar artery aneurysm by vertebral artery occlusion continued to have progressive neurologic deficits. One patient with a cavernous aneurysm had upper extremity weakness and mild dysphasia 24 hours after internal carotid artery occlusion. CONCLUSION: In our small series, microcoils were found to be safe and effective for neurovascular occlusion. When both intravenous heparin (5000 U IV bolus) and heparinized catheter flush solutions (5000 U/L) are used, flow arrest during coil placement is unnecessary to prevent clinically apparent embolic complications.  (+info)

Management of a rare complication of endovascular treatment of direct carotid cavernous fistula. (2/104)

A 30-year-old woman with direct carotid cavernous fistula underwent endovascular treatment with detachable balloons via a transarterial route. The patient returned with diplopia 1 year after therapy. On cranial MR imaging, one of the balloons was detected in the proximal portion of the superior ophthalmic vein and was deflated percutaneously with a 22-gauge Chiba needle under CT guidance. The patient's symptoms resolved after balloon deflation. This case report presents a unique complication of endovascular treatment of direct carotid cavernous fistula and its management.  (+info)

Cavernous sinus and inferior petrosal sinus flow signal on three-dimensional time-of-flight MR angiography. (3/104)

BACKGROUND AND PURPOSE: Venous flow signal in the cavernous sinus and inferior petrosal sinus has been shown on MR angiograms in patients with carotid cavernous fistula (CCF). We, however, identified flow signal in some patients without symptoms and signs of CCF. This review was performed to determine the frequency of such normal venous flow depiction at MR angiography. METHODS: Twenty-five 3D time-of-flight (TOF) MR angiograms obtained on two different imaging units (scanners A and B) were reviewed with attention to presence of venous flow signal in the cavernous sinus or inferior petrosal sinus or both. Twenty-five additional MR angiograms were reviewed in patients who had also had cerebral arteriography to document absence of CCF where venous MR angiographic signal was detected, as well as to gain insight into venous flow patterns that might contribute to MR angiographic venous flow signal. Differences in scanning technique parameters were reviewed. RESULTS: Nine (36%) of the 25 MR angiograms obtained on scanner A but only one (4%) of the 25 obtained on scanner B showed flow signal in the cavernous or inferior petrosal sinus or both in the absence of signs of CCF. On review of 25 patients who had both MR angiography and arteriography, three patients with venous signal at MR angiography failed to exhibit CCF at arteriography. CONCLUSION: Identification of normal cavernous sinus or inferior petrosal sinus venous signal on 3D TOF MR angiograms may occur frequently, and is probably dependent on technical factors that vary among scanners. The exact factors most responsible, however, were not elucidated by this preliminary review.  (+info)

Direct carotid-cavernous sinus fistula due to ruptured intracavernous aneurysm treated with electrodetachable coils--case report. (4/104)

A 66-year-old female developed exophthalmos, impaired visual acuity (perception of light), and diplopia one day after sudden onset of headache. Neurological examination revealed proptosis, chemosis, impaired vision, and ophthalmoplegia. Carotid angiography showed direct carotid-cavernous sinus fistula concomitant with an intracavernous aneurysm on the right side. Intraaneurysmal embolization using the Guglielmi detachable coils (GDCs) via the transarterial route was performed and complete occlusion of the fistula successfully achieved. The neurological deficits resolved completely by 6 months after embolization. Intraaneurysmal GDC embolization via the transarterial route may be an alternative for the treatment of direct carotid-cavernous sinus fistula due to rupture of intracavernous aneurysm.  (+info)

Carotid and transcranial color-coded duplex sonography in different types of carotid-cavernous fistula. (5/104)

BACKGROUND AND PURPOSE: Patients with carotid-cavernous fistula (CCF) may undergo direct or indirect shunting. Ultrasonography has value that is complementary to angiography in the assessment and follow-up of these patients. The aim of this study was to characterize findings provided by carotid duplex sonography (CDS) and transcranial color-coded duplex sonography (TCCD) in patients with different types of CCF. METHODS: CDS and TCCD were independently performed by technologists and neurologists. Digital subtraction or MR angiography was interpreted by a neuroradiologist. Ultrasonographic studies were categorized into 4 types: I, direct shunting only; II, direct shunting with a carotid aneurysm; III, indirect shunting only; and IV, mixed (direct and indirect) shunting. In addition to carotid and intracranial flow velocities, volume, and pulsatility, other direct and indirect ultrasound signs of shunting were evaluated. The direct sign of CCF was a mosaic flash detected by TCCD. Alteration of hemodynamic parameters on CDS and demonstration of draining veins with the use of TCCD were considered indirect signs. RESULTS: Fifteen patients (8 men, 7 women) were included in the study. According to angiographic results, patients in ultrasonographic classification types I (n=7) and II (n=3) corresponded to type A of Barrow's classification. Patients with type III (n=8) were Barrow's type C. Type IV (n=1) had a combination of Barrow's types A and C. On ultrasound, both direct and indirect signs were seen in types I, II, and IV CCF. The presence of a 2-colored oval mass divided by a zone of separation without turbulence differentiated type I from type II CCF. All patients with type III CCF had indirect signs, and only 1 patient had direct signs on TCCD. Abnormal TCCD findings were most commonly seen through the transorbital window (100%), followed by the transtemporal window (63%) and transforaminal window (40%). CONCLUSIONS: If only indirect ultrasonographic signs of CCF are present, TCCD can be used to predict an indirect CCF type on the basis of the origin of the fistula. With direct communication between carotid artery and cavernous sinus, both direct and indirect ultrasonographic signs can be found. The combination of CDS/TCCD may provide a noninvasive and reliable way to classify patients with CCF.  (+info)

Transvenous embolization of carotid-cavernous sinus fistula associated with a primitive trigeminal artery--case report. (6/104)

A 58-year-old female presented with right conjunctival chemosis and right abducens nerve paresis. Cerebral angiography demonstrated a right carotid-cavernous sinus fistula associated with persistent primitive trigeminal artery. The fistula was treated by introducing detachable coils through the transvenous approach, as the detachable balloon was not available. Follow-up angiography performed 14 days after the embolization revealed complete disappearance of the carotid-cavernous sinus fistula due to thrombosis, which was presumably accelerated by the coils. Transvenous coil embolization should be considered as an alternative treatment for high-flow carotid-cavernous sinus fistula, but only if transarterial balloon embolization is not successful or unavailable.  (+info)

Extracranial carotid artery aneurysms: Texas Heart Institute experience. (7/104)

BACKGROUND AND PURPOSE: Aneurysms of the extracranial carotid artery (ECA) are rare. Large single-institution series are seldom reported and usually are not aneurysm type-specific. Thus, information about immediate and long-term results of surgical therapy is sparse. This review was conducted to elucidate etiology, presentation, and treatment for ECA aneurysms. METHODS: We retrospectively reviewed the case records of the Texas Heart Institute/St Luke's Episcopal Hospital, Houston, and found 67 cases of ECA aneurysms treated surgically (the largest series to date) between 1960 and 1995: 38 pseudoaneurysms after previous carotid surgery and 29 atherosclerotic or traumatic aneurysms. All aneurysms were surgically explored, and all were repaired except two: a traumatic distal internal carotid artery aneurysm and an infected pseudoaneurysm in which the carotid artery was ligated. RESULTS: Four deaths (three fatal strokes and one myocardial infarction) and two nonfatal strokes were directly attributed to a repaired ECA aneurysm (overall mortality/major stroke incidence, 9%); there was one minor stroke (incidence, 1.5%). The incidence of cranial nerve injury was 6% (four cases). During long-term follow-up (1.5 months-30 years; mean, 5.9 years), 19 patients died, mainly of cardiac causes (11 myocardial infarctions). CONCLUSION: The potential risks of cerebral ischemia and rupture as well as the satisfactory long-term results achieved with surgery strongly argue in favor of surgical treatment of ECA aneurysms.  (+info)

N2 - Endovascular embolization is the preferred treatment for carotid-cavernous fistulas (CCFs), but failure to catheterize the cavernous sinus may occur as a result of tortuosity, hypoplasia, or stenosis of the normal venous routes. In these cases, direct operative cannulation of the arterialized superior ophthalmic vein (SOV) offers an excellent alternative approach. We reviewed the records of patients who underwent surgical cannulation of the SOV in preparation for embolization and identified 10 patients with indirect CCF, all of whom presented with ocular signs and symptoms. All had previously undergone unsuccessful endovenous attempts at treatment at our ...
A carotid-cavernous fistula (CCF) results from an abnormal communication between the arterial and venous systems within the cavernous sinus in the skull. It is a type of arteriovenous fistula. 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. Carotid cavernous fistulae may form following closed or penetrating head trauma, surgical damage, rupture of an intracavernous aneurysm, or in association with connective tissue disorders, vascular diseases and dural fistulas. Various classifications have been proposed for CCF. They may be divided into low-flow or high-flow, traumatic or spontaneous and direct or indirect. The traumatic CCF typically occurs after a basal skull fracture. The spontaneous dural cavernous fistula which is more common usually results from a degenerative process ...

Carotid cavernous fistulas are abnormal communications between the carotid artery and the cavernous sinus, either directly or via intradural branches of the internal or external carotid arteries.1 Direct fistulas are high flow, frequently follow trauma, and tend to have a dramatic clinical presentation. In contrast, indirect fistulas are low flow, often spontaneous, and may have a subtle clinical presentation. Symptoms and signs common to both types of fistulas include proptosis, chemosis, diplopia, visual loss, pulse-synchronous tinnitus, orbital bruit, elevated intraocular pressure, dilated episcleral veins, and retinal venous congestion. The pattern of venous drainage, either anterior into the ophthalmic veins or posterior into the petrosal sinuses, often dictates the clinical findings and radiographic appearance. Anterior drainage typically leads to the most dramatic ocular findings and enlargement of the superior orbital vein, the latter often detectable with CT or MRI. However, superior ...
Vertebral-venous fistulas (VVF), or vertebral-vertebral arteriovenous fistulas, are an uncommon clinical entity. Typically, they present as a result of a direct vascular connection between an extracranial branch of the vertebral artery or its radicular components and the epidural venous plexus. These may manifest with signs and symptoms referable to cervical myelopathy secondary to compression or steal phenomenon. To our knowledge, this is the first case to identify a patient who presented with classic ocular symptoms attributable to a carotid cavernous fistula but secondary to a VVF. We present its treatment and clinical outcome. In addition, we present a brief literature review surrounding this uncommon disease. ...

Quantitative DSA facilitates real-time hemodynamic monitoring and helps determine the optimal angioplasty in carotid stenosis to avoid hyperperfusion4 and the end point of embolization in carotid cavernous fistulas.8,10 A previous study by Lin et al8 in 2012 showed significant reduction in rTTP at the ICA (in both PA and lateral views), A1, M1, and M2 after stent placement compared with pretreatment data. Lin et al10 reported a study of cerebral circulation time by calculating the rTTP relative to the cervical ICA on the PA view (same location as ICA1 in our report) and relative to the cavernous segment of the ICA on the lateral view (same location as ICA2 in our report). We found that the poststenting mean circulation times of M1, M2, and PV (corresponding to rTTP of the following segments: ICA1-M1, ICA2-M2, and ICA2-PV) in our study (0.49, 0.50, and 4.14 seconds, respectively) were close to those of healthy controls (0.46, 0.58, and 4.38 seconds, respectively).10 Therefore, the cerebral ...
Several classifications of CCF exist depending on anatomy, aetiology, and pathophysiology. One categorisation divides between traumatic and spontaneous fistulas. Another classification is established according to fistulous supply to the cavernous sinus as follows: type A, internal carotid artery (ICA); type B, dural branches of the ICA; type C, dural branches of the external carotid artery (ECA); type D, combined forms.1 2 This leads to a further classification into direct, high flow, and indirect low flow fistulas because therapeutic management of CCF is strongly dependent on their haemodynamics.3-5 Finally, considering aetiology, there are several entities responsible for the development of a CCF: closed or penetrating head trauma, surgical damage, rupture of an intracavernous aneurysm, connective tissue disorders, vascular disease, and dural fistulas.6 7 Direct shunting CCFs are mainly caused by a tear of the internal carotid artery itself. In most cases, these CCFs are high flow, and ...

Dr Chinh Nguyen1, A/Prof Nitin Verma1. 1Royal Hobart Hospital , Hobart, Australia. 78 year-old female presented with proptosis, lid chemosis and diplopia on the right eye. The patient never had a history of head trauma or any other significant trauma. Magnetic resonance imaging angiography showed a thrombosed varix of the superior ophthalmic vein, with no evidence of dural arteriovenous fistula or vascular malformation. Digital subtraction angiography (DSA) was performed one week following the initial presentation, and in the mean time the patient was admitted for observation without anticoagulation. DSA found the thrombosed varix to have re-vascularised on its own at day seven of admission. All symptoms subsided after 2 weeks of the intial presentation. This case study demonstrated that an isolated thrombosed varix of an ophthalmic vein may resolve on its own, without the need for anticoagulation or surgery.. ...
Roughly 10% to 32% of the population has a fetal origin PCA supplying their parieto-occipital lobes in which the P1 segment is hypoplastic and the PCA is supplied primarily by a larger diameter homolateral posterior communicating artery [5, 10]. Other potentially persistent primitive carotid basilar anastomoses include the primitive trigeminal artery, the primitive acoustic (otic) artery, the primitive hypoglossal artery, and the primitive proatlantic artery. The fetal origin PCA anatomic variant provides a potential conduit for emboli from ipsilateral ICA disease [6-9]. To the best of our knowledge, artery-to-artery embolism from cervical ICA pseudoaneurysm to fetal PCA has not been previously reported. Pseudoaneurysm usually develops as a result of trauma, with rupture of the affected artery through the intima and media into the subadventitial plane. The resulting tear is contained by the adventitia forming a pseudoaneurysm. Unlike true aneurysms, pseudoaneurysms do not involve dilatation of ...

Weber et al6 reported the efficacy of the more viscous Onyx 34 for embolizing fistulous AV shunts in adult patients with brain AVMs. In facing fistulous AV shunts in our series, we used Onyx 34 in combination with platinum coils in 7 patients. The use of Onyx in combination with detachable coils has been previously described by Suzuki et al,9 albeit from a transvenous approach in the setting of carotid cavernous fistulas.. Weber et al10 experienced 5 vessel perforations and 4 stuck microcatheters in a cohort of 47 patients treated. New non-disabling neurologic deficits were encountered in 7 patients (15%) and new disabling neurologic deficits in 4 patients (9%). Delayed hemorrhage after embolization occurred in 2 patients (4%). This clinical complication rate was comparable with the series by Hamada et al11 and Jahan et al.4. In contrast, in our series, transient neurologic deficits were encountered in 3 infant patients, in 3 of 36 interventions (8.3%), including 2 cases of transient worsening ...

Transorbital penetration accounts for one-quarter of the penetrating head injuries (PHIs) in adults and half of those in children. Injuries that traverse (with complete penetration of) the brainstem are often fatal, with survivors rarely seen in clinical practice. Here, the authors describe the case of a 16-year-old male who suffered and recovered from an accidental transorbital PHI traversing the brainstem-the first case of complete neurological recovery following such injury. Neuroimaging captured the trajectory of the initial injury. A delayed-onset carotid cavernous fistula and the subsequent development of internal carotid artery pseudoaneurysms were managed by endovascular embolization.. The authors also review the relevant literature. Sixteen cases of imaging-confirmed PHI traversing the brainstem have been reported, 14 involving the pons and 12 penetrating via the transorbital route. Management and outcome of PHI are informed by object velocity, material, entry point, trajectory, ...

The task of tracing visual language in book design is a challenge, but one that is useful to take up in order to help us understand how readers make meaning of what they read. Studying the lineage of some forms of layout also sheds light on how design fits into and contributes to culture in a wider sense. Childrens science books - the highly graphic and colourful ones published over the last 30 years or so in the UK - provide some excellent examples of complex visual language, partly because they tend to be more highly illustrated than books meant for adults. But how do diagrams, illustrations and different forms of text interact to produce content in these books? Meaning does not reside in the book alone, but is dependent on context: the particular conditions of reading, and the wider social and cultural environment. This is an exploration of book design as a medium of communication.. Many changes have occurred in British childrens publishing over the past 30 years. These have had a visible ...

Pulsating proptosis may be due to carotid-cavernous fistula, arterial orbital vascular malformation, or transmission of cerebral pulsations due to a bone defect such as in the sphenoid dysplasia of type 1 neurofibromatosis. Proptosis that increases on bending the head forward or with Valsalva maneuver can be a sign of venous orbital vascular malformation (orbital varices) or bone defect. Intermittent proptosis may be the result of a sinus mucocele. The Hertel exophthalmometer (see Chapter 2) is the standard method of quantifying the magnitude of proptosis. Serial measurements are most accurate if performed by the same individual with the same instrument. Pseudoproptosis is apparent proptosis in the absence of orbital disease. It may be due to an enlarged globe from high myopia or buphthalmos, lid retraction, extraocular muscle weakness or paralysis, asymmetrical orbital size, or posterior displacement (enophthalmos) of the contralateral globe. ...

Chemosis is the swelling (or edema) of the conjunctiva. It is due to the oozing of exudate from abnormally permeable capillaries. In general, chemosis is a nonspecific sign of eye irritation. The outer surface covering appears to have fluid in it. The conjunctiva becomes swollen and gelatinous in appearance. Often, the eye area swells so much that the eyes become difficult or impossible to close fully.[1] Sometimes, it may also appear as if the eyeball has moved slightly backwards from the white part of the eye due to the fluid filled in the conjunctiva all over the eyes except the iris. The iris is not covered by this fluid and so it appears to be moved slightly inwards.. ...

A 67-year-old woman was admitted for retro-orbital and periorbital pain, increasing over 1 week and accompanied by progressive exophthalmia and palpebral ptosis on the left side. She was being treated for lung cancer metastasized to the liver and cerebellum. Physical examination revealed a complete ptosis of the left eyelid and complete absence of extraocular movements of the left eye, referable to the third, fourth and sixth cranial nerve. Head computed tomography (CT) showed mucous thickening of the left sphenoid and maxillary sinuses. Brain MRI revealed an expansive lesion involving the left cavernous sinus (Figure 1), which proved to be a new occurrence by comparison with a contrast-enhanced CT performed several weeks earlier. The lesion in the cavernous sinus appeared to be inseparable from T2-hypointense changes in the posterior part of the left sphenoid sinus (Figure 2a,b), whereas the remaining wall thickening of the ethmoidal, sphenoid and maxillary sinuses appeared to be smooth and ...
