Cavernous Sinus: An irregularly shaped venous space in the dura mater at either side of the sphenoid bone.Carotid-Cavernous Sinus Fistula: An acquired or spontaneous abnormality in which there is communication between CAVERNOUS SINUS, a venous structure, and the CAROTID ARTERIES. It is often associated with HEAD TRAUMA, specifically basilar skull fractures (SKULL FRACTURE, BASILAR). Clinical signs often include VISION DISORDERS and INTRACRANIAL HYPERTENSION.Arteriovenous Fistula: 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.Cavernous Sinus Thrombosis: Formation or presence of a blood clot (THROMBUS) in the CAVERNOUS SINUS of the brain. Infections of the paranasal sinuses and adjacent structures, CRANIOCEREBRAL TRAUMA, and THROMBOPHILIA are associated conditions. Clinical manifestations include dysfunction of cranial nerves III, IV, V, and VI, marked periorbital swelling, chemosis, fever, and visual loss. (From Adams et al., Principles of Neurology, 6th ed, p711)Fistula: Abnormal communication most commonly seen between two internal organs, or between an internal organ and the surface of the body.Respiratory Tract Fistula: An abnormal passage communicating between any component of the respiratory tract or between any part of the respiratory system and surrounding organs.Pyriform Sinus: A recess on each side in the wall of the HYPOPHARYNX.Thyroiditis, Suppurative: Acute inflammatory disease of the THYROID GLAND due to infections by BACTERIA; FUNGI; or other microorganisms. Symptoms include tender swelling, FEVER, and often with LEUKOCYTOSIS.Carotid Artery Diseases: Pathological conditions involving the CAROTID ARTERIES, including the common, internal, and external carotid arteries. ATHEROSCLEROSIS and TRAUMA are relatively frequent causes of carotid artery pathology.Carotid Arteries: Either of the two principal arteries on both sides of the neck that supply blood to the head and neck; each divides into two branches, the internal carotid artery and the external carotid artery.Carotid Artery, Internal: Branch of the common carotid artery which supplies the anterior part of the brain, the eye and its appendages, the forehead and nose.Dura Mater: The outermost of the three MENINGES, a fibrous membrane of connective tissue that covers the brain and the spinal cord.Embolization, Therapeutic: A method of hemostasis utilizing various agents such as Gelfoam, silastic, metal, glass, or plastic pellets, autologous clot, fat, and muscle as emboli. It has been used in the treatment of spinal cord and INTRACRANIAL ARTERIOVENOUS MALFORMATIONS, renal arteriovenous fistulas, gastrointestinal bleeding, epistaxis, hypersplenism, certain highly vascular tumors, traumatic rupture of blood vessels, and control of operative hemorrhage.Carotid Stenosis: Narrowing or stricture of any part of the CAROTID ARTERIES, most often due to atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce THROMBUS formation. Platelet or cholesterol emboli may arise from stenotic carotid lesions and induce a TRANSIENT ISCHEMIC ATTACK; CEREBROVASCULAR ACCIDENT; or temporary blindness (AMAUROSIS FUGAX). (From Adams et al., Principles of Neurology, 6th ed, pp 822-3)Sphenoid Sinus: One of the paired air spaces located in the body of the SPHENOID BONE behind the ETHMOID BONE in the middle of the skull. Sphenoid sinus communicates with the posterosuperior part of NASAL CAVITY on the same side.Intestinal Fistula: An abnormal anatomical passage between the INTESTINE, and another segment of the intestine or other organs. External intestinal fistula is connected to the SKIN (enterocutaneous fistula). Internal intestinal fistula can be connected to a number of organs, such as STOMACH (gastrocolic fistula), the BILIARY TRACT (cholecystoduodenal fistula), or the URINARY BLADDER of the URINARY TRACT (colovesical fistula). Risk factors include inflammatory processes, cancer, radiation treatment, and surgical misadventures (MEDICAL ERRORS).Coronary Sinus: A short vein that collects about two thirds of the venous blood from the MYOCARDIUM and drains into the RIGHT ATRIUM. Coronary sinus, normally located between the LEFT ATRIUM and LEFT VENTRICLE on the posterior surface of the heart, can serve as an anatomical reference for cardiac procedures.Cranial Sinuses: Large endothelium-lined venous channels situated between the two layers of DURA MATER, the endosteal and the meningeal layers. They are devoid of valves and are parts of the venous system of dura mater. Major cranial sinuses include a postero-superior group (such as superior sagittal, inferior sagittal, straight, transverse, and occipital) and an antero-inferior group (such as cavernous, petrosal, and basilar plexus).Cutaneous Fistula: An abnormal passage or communication leading from an internal organ to the surface of the body.Cerebral Angiography: Radiography of the vascular system of the brain after injection of a contrast medium.Central Nervous System Vascular Malformations: Congenital, inherited, or acquired abnormalities involving ARTERIES; VEINS; or venous sinuses in the BRAIN; SPINAL CORD; and MENINGES.Carotid Sinus: The dilated portion of the common carotid artery at its bifurcation into external and internal carotids. It contains baroreceptors which, when stimulated, cause slowing of the heart, vasodilatation, and a fall in blood pressure.Bronchial Fistula: An abnormal passage or communication between a bronchus and another part of the body.Vascular Fistula: An abnormal passage between two or more BLOOD VESSELS, between ARTERIES; VEINS; or between an artery and a vein.Barium Sulfate: A compound used as an x-ray contrast medium that occurs in nature as the mineral barite. It is also used in various manufacturing applications and mixed into heavy concrete to serve as a radiation shield.Rectal Fistula: An abnormal anatomical passage connecting the RECTUM to the outside, with an orifice at the site of drainage.Abducens Nerve Diseases: Diseases of the sixth cranial (abducens) nerve or its nucleus in the pons. The nerve may be injured along its course in the pons, intracranially as it travels along the base of the brain, in the cavernous sinus, or at the level of superior orbital fissure or orbit. Dysfunction of the nerve causes lateral rectus muscle weakness, resulting in horizontal diplopia that is maximal when the affected eye is abducted and ESOTROPIA. Common conditions associated with nerve injury include INTRACRANIAL HYPERTENSION; CRANIOCEREBRAL TRAUMA; ISCHEMIA; and INFRATENTORIAL NEOPLASMS.Gastric Fistula: Abnormal passage communicating with the STOMACH.Urinary Fistula: An abnormal passage in any part of the URINARY TRACT between itself or with other organs.Esophageal Fistula: Abnormal passage communicating with the ESOPHAGUS. The most common type is TRACHEOESOPHAGEAL FISTULA between the esophagus and the TRACHEA.Endarterectomy, Carotid: The excision of the thickened, atheromatous tunica intima of a carotid artery.Pharyngeal Diseases: Pathological processes involving the PHARYNX.Ophthalmoplegia: Paralysis of one or more of the ocular muscles due to disorders of the eye muscles, neuromuscular junction, supporting soft tissue, tendons, or innervation to the muscles.Cranial Nerves: Twelve pairs of nerves that carry general afferent, visceral afferent, special afferent, somatic efferent, and autonomic efferent fibers.Biliary Fistula: Abnormal passage in any organ of the biliary tract or between biliary organs and other organs.Sinus Thrombosis, Intracranial: Formation or presence of a blood clot (THROMBUS) in the CRANIAL SINUSES, large endothelium-lined venous channels situated within the SKULL. Intracranial sinuses, also called cranial venous sinuses, include the superior sagittal, cavernous, lateral, petrous sinuses, and many others. Cranial sinus thrombosis can lead to severe HEADACHE; SEIZURE; and other neurological defects.Cranial Fossa, Middle: The compartment containing the anterior extremities and half the inferior surface of the temporal lobes (TEMPORAL LOBE) of the cerebral hemispheres. Lying posterior and inferior to the anterior cranial fossa (CRANIAL FOSSA, ANTERIOR), it is formed by part of the TEMPORAL BONE and SPHENOID BONE. It is separated from the posterior cranial fossa (CRANIAL FOSSA, POSTERIOR) by crests formed by the superior borders of the petrous parts of the temporal bones.Cerebral Veins: Veins draining the cerebrum.Sphenoid Bone: An irregular unpaired bone situated at the SKULL BASE and wedged between the frontal, temporal, and occipital bones (FRONTAL BONE; TEMPORAL BONE; OCCIPITAL BONE). Sphenoid bone consists of a median body and three pairs of processes resembling a bat with spread wings. The body is hollowed out in its inferior to form two large cavities (SPHENOID SINUS).Tomography, X-Ray Computed: Tomography using x-ray transmission and a computer algorithm to reconstruct the image.Pancreatic Fistula: Abnormal passage communicating with the PANCREAS.Carotid Artery, Common: The two principal arteries supplying the structures of the head and neck. They ascend in the neck, one on each side, and at the level of the upper border of the thyroid cartilage, each divides into two branches, the external (CAROTID ARTERY, EXTERNAL) and internal (CAROTID ARTERY, INTERNAL) carotid arteries.Carotid Body: A small cluster of chemoreceptive and supporting cells located near the bifurcation of the internal carotid artery. The carotid body, which is richly supplied with fenestrated capillaries, senses the pH, carbon dioxide, and oxygen concentrations in the blood and plays a crucial role in their homeostatic control.Rectovaginal Fistula: An abnormal anatomical passage between the RECTUM and the VAGINA.Abscess: Accumulation of purulent material in tissues, organs, or circumscribed spaces, usually associated with signs of infection.Maxillary Sinus: The air space located in the body of the MAXILLARY BONE near each cheek. Each maxillary sinus communicates with the middle passage (meatus) of the NASAL CAVITY on the same side.Sella Turcica: A bony prominence situated on the upper surface of the body of the sphenoid bone. It houses the PITUITARY GLAND.Oculomotor Nerve Diseases: Diseases of the oculomotor nerve or nucleus that result in weakness or paralysis of the superior rectus, inferior rectus, medial rectus, inferior oblique, or levator palpebrae muscles, or impaired parasympathetic innervation to the pupil. With a complete oculomotor palsy, the eyelid will be paralyzed, the eye will be in an abducted and inferior position, and the pupil will be markedly dilated. Commonly associated conditions include neoplasms, CRANIOCEREBRAL TRAUMA, ischemia (especially in association with DIABETES MELLITUS), and aneurysmal compression. (From Adams et al., Principles of Neurology, 6th ed, p270)Vesicovaginal Fistula: An abnormal anatomical passage between the URINARY BLADDER and the VAGINA.Thyroiditis: Inflammatory diseases of the THYROID GLAND. Thyroiditis can be classified into acute (THYROIDITIS, SUPPURATIVE), subacute (granulomatous and lymphocytic), chronic fibrous (Riedel's), chronic lymphocytic (HASHIMOTO DISEASE), transient (POSTPARTUM THYROIDITIS), and other AUTOIMMUNE THYROIDITIS subtypes.Carotid Artery, External: Branch of the common carotid artery which supplies the exterior of the head, the face, and the greater part of the neck.Vaginal Fistula: An abnormal anatomical passage that connects the VAGINA to other organs, such as the bladder (VESICOVAGINAL FISTULA) or the rectum (RECTOVAGINAL FISTULA).
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.

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.

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.

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 ...

Magnetic resonance angiography source images in carotid cavernous fistulas | British Journal of Ophthalmology
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 fistula: an unusual cause for ocular symptoms mimicking a carotid cavernous fistula | Journal of...
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. ...

Methods This is a prospective case series of 29 patients who had traumatic cavernous carotid injury or spontaneous hemorrhage who had placement of one or more stent grafts in the cavernous carotid artery for treatment. Patients were loaded with either 300 mg or 600 mg of clopidogrel and 325 mg of aspirin either a few hours prior to the endovascular procedure or via an oral gastric tube at the time of the procedure. Patient also received intraprocedure intravenous heparin. They were then maintained on clopidogrel and aspirin for 6 months and then aspirin alone from then on. Follow-up imaging was performed at 6 months post intervention, and patients were then followed up clinical on an annual basis. ...

Carotid-cavernous fistula (CCF) generally causes periorbital aching with ocular symptoms due to high venous pressure in the cavernous sinus, while migraine is caused by arterial dilatation-stimulating trigeminal nerves around the vessels. The authors present a case of 47-year-old woman with a 4-month history of a temporal throbbing headache. As her ...
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 ...

Circuitous embolic hemorrhagic stroke: carotid pseudoaneurysm to fetal posterior cerebral artery conduit: a case report |...
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 ...

Complete recovery following transorbital penetrating head injury traversing the brainstem: case report in: Journal of...
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, ...

Hello. Im a first time poster...one week lurker :) I have just been diagnosed with a 1.8cm Cavernous Carotid Aneurysm. My Cerebral Angiogram was 3 days ago. My neurosurgeon wants to do a stent (no coils) which Ive come to terms with. My question is, the doctor used a StarClose closure, which Im just finding out is made of Nickel and Titanium, and I have a sensitivity/allergy to Nickel. Has anyone who is sensitive or allergic to Nickel had this and had any issues or reactions withe
Noninvasive imaging modalities, particularly CT angiography (CTA) and MRA, have been gaining acceptance as practical alternatives to DSA for the diagnosis of cerebrovascular disease. This is evident throughout the recent radiologic literature and in the daily practice of neuroradiologic departments. However, DSA has remained the technique of choice for evaluation of patients with a suspected DAVF. DAVFs are commonly very small lesions requiring the high spatial resolution of DSA for their identification. In addition to high spatial resolution, a need for adequate temporal resolution is also warranted because the normal cerebrovascular circuit is 5 to 8 s from the cavernous carotid to the transverse sinus, and one must be able to identify not only the early opacification of a dural sinus, but also reflux into the connecting cortical veins, if present. Aside from its obvious drawbacks of patient discomfort, expense, and risks, DSA is ideal for investigation of DAVFs because of its inherent spatial ...
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 ...

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. 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 ...

Figure 2. Formation of ophiolitic chromitites according to the new mechanism of crystallisation proposed in this work. A network of dunite channels drains melts ascending from different sources (marked with different colours) in the heterogeneous deeper mantle (modified from Kelemen, 2004). (1) Ascending melts move mainly by porous percolation through a melt-film network; in the zone of intersection between dunite channels mixing of basaltic melts with different SiO2 promotes precipitation of chromite. The image is not to scale, as grains of olivine are generally from , 0.5 mm to a few centimeters. (2) Focused flow of melt produces melt-filled channels in dunite allowing the chemical isolation and rapid ascent of the melts. (3) Chemically isolated melts drained through different channels in the dunite meet and mix to produce hybrid melts able to precipitate volumes of chromitite. The size of the dunite network and the chromitite bodies can vary from a few metres to many kilometers.. The ...
