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).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.Paranasal Sinuses: Air-filled spaces located within the bones around the NASAL CAVITY. They are extensions of the nasal cavity and lined by the ciliated NASAL MUCOSA. Each sinus is named for the cranial bone in which it is located, such as the ETHMOID SINUS; the FRONTAL SINUS; the MAXILLARY SINUS; and the SPHENOID SINUS.Cavernous Sinus: An irregularly shaped venous space in the dura mater at either side of the sphenoid bone.Sinus of Valsalva: The dilatation of the aortic wall behind each of the cusps of the aortic valve.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.Frontal Sinus: One of the paired, but seldom symmetrical, air spaces located between the inner and outer compact layers of the FRONTAL BONE in the forehead.Paranasal Sinus Diseases: Diseases affecting or involving the PARANASAL SINUSES and generally manifesting as inflammation, abscesses, cysts, or tumors.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.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.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.Sick Sinus Syndrome: A condition caused by dysfunctions related to the SINOATRIAL NODE including impulse generation (CARDIAC SINUS ARREST) and impulse conduction (SINOATRIAL EXIT BLOCK). It is characterized by persistent BRADYCARDIA, chronic ATRIAL FIBRILLATION, and failure to resume sinus rhythm following CARDIOVERSION. This syndrome can be congenital or acquired, particularly after surgical correction for heart defects.Ethmoid Sinus: The numerous (6-12) small thin-walled spaces or air cells in the ETHMOID BONE located between the eyes. These air cells form an ethmoidal labyrinth.Paranasal Sinus Neoplasms: Tumors or cancer of the PARANASAL SINUSES.Tachycardia, Sinus: Simple rapid heartbeats caused by rapid discharge of impulses from the SINOATRIAL NODE, usually between 100 and 180 beats/min in adults. It is characterized by a gradual onset and termination. Sinus tachycardia is common in infants, young children, and adults during strenuous physical activities.Maxillary Sinus Neoplasms: Tumors or cancer of the MAXILLARY SINUS. They represent the majority of paranasal neoplasms.Pilonidal Sinus: A hair-containing cyst or sinus, occurring chiefly in the coccygeal region.Transverse Sinuses: The two large endothelium-lined venous channels that begin at the internal occipital protuberance at the back and lower part of the CRANIUM and travels laterally and forward ending in the internal jugular vein (JUGULAR VEINS). One of the transverse sinuses, usually the right one, is the continuation of the SUPERIOR SAGITTAL SINUS. The other transverse sinus is the continuation of the straight sinus.Superior Sagittal Sinus: The long large endothelium-lined venous channel on the top outer surface of the brain. It receives blood from a vein in the nasal cavity, runs backwards, and gradually increases in size as blood drains from veins of the brain and the DURA MATER. Near the lower back of the CRANIUM, the superior sagittal sinus deviates to one side (usually the right) and continues on as one of the TRANSVERSE SINUSES.Sinoatrial Node: The small mass of modified cardiac muscle fibers located at the junction of the superior vena cava (VENA CAVA, SUPERIOR) and right atrium. Contraction impulses probably start in this node, spread over the atrium (HEART ATRIUM) and are then transmitted by the atrioventricular bundle (BUNDLE OF HIS) to the ventricle (HEART VENTRICLE).Ethmoid Bone: A light and spongy (pneumatized) bone that lies between the orbital part of FRONTAL BONE and the anterior of SPHENOID BONE. Ethmoid bone separates the ORBIT from the ETHMOID SINUS. It consists of a horizontal plate, a perpendicular plate, and two lateral labyrinths.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).Frontal Bone: The bone that forms the frontal aspect of the skull. Its flat part forms the forehead, articulating inferiorly with the NASAL BONE and the CHEEK BONE on each side of the face.Skull: The SKELETON of the HEAD including the FACIAL BONES and the bones enclosing the BRAIN.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)Sphenoid Sinusitis: Inflammation of the NASAL MUCOSA in the SPHENOID SINUS. Isolated sphenoid sinusitis is uncommon. It usually occurs in conjunction with other paranasal sinusitis.Oculomotor Nerve: The 3d cranial nerve. The oculomotor nerve sends motor fibers to the levator muscles of the eyelid and to the superior rectus, inferior rectus, and inferior oblique muscles of the eye. It also sends parasympathetic efferents (via the ciliary ganglion) to the muscles controlling pupillary constriction and accommodation. The motor fibers originate in the oculomotor nuclei of the midbrain.Cranial Nerve Diseases: Disorders of one or more of the twelve cranial nerves. With the exception of the optic and olfactory nerves, this includes disorders of the brain stem nuclei from which the cranial nerves originate or terminate.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.Meninges: The three membranes that cover the BRAIN and the SPINAL CORD. They are the dura mater, the arachnoid, and the pia mater.Anatomy: A branch of biology dealing with the structure of organisms.Cerebrospinal Fluid: A watery fluid that is continuously produced in the CHOROID PLEXUS and circulates around the surface of the BRAIN; SPINAL CORD; and in the CEREBRAL VENTRICLES.Dura Mater: The outermost of the three MENINGES, a fibrous membrane of connective tissue that covers the brain and the spinal cord.Otolaryngology: A surgical specialty concerned with the study and treatment of disorders of the ear, nose, and throat.Meningioma: A relatively common neoplasm of the CENTRAL NERVOUS SYSTEM that arises from arachnoidal cells. The majority are well differentiated vascular tumors which grow slowly and have a low potential to be invasive, although malignant subtypes occur. Meningiomas have a predilection to arise from the parasagittal region, cerebral convexity, sphenoidal ridge, olfactory groove, and SPINAL CANAL. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, pp2056-7)Otorhinolaryngologic Diseases: Pathological processes of the ear, the nose, and the throat, also known as the ENT diseases.Otorhinolaryngologic Surgical Procedures: Surgery performed on the ear and its parts, the nose and nasal cavity, or the throat, including surgery of the adenoids, tonsils, pharynx, and trachea.Cranial Nerves: Twelve pairs of nerves that carry general afferent, visceral afferent, special afferent, somatic efferent, and autonomic efferent fibers.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)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.Semicircular Canals: Three long canals (anterior, posterior, and lateral) of the bony labyrinth. They are set at right angles to each other and are situated posterosuperior to the vestibule of the bony labyrinth (VESTIBULAR LABYRINTH). The semicircular canals have five openings into the vestibule with one shared by the anterior and the posterior canals. Within the canals are the SEMICIRCULAR DUCTS.Ear Diseases: Pathological processes of the ear, the hearing, and the equilibrium system of the body.Hearing Loss, Conductive: Hearing loss due to interference with the mechanical reception or amplification of sound to the COCHLEA. The interference is in the outer or middle ear involving the EAR CANAL; TYMPANIC MEMBRANE; or EAR OSSICLES.Vestibular Evoked Myogenic Potentials: Recorded electrical responses from muscles, especially the neck muscles or muscles around the eyes, following stimulation of the EAR VESTIBULE.Bone Conduction: Transmission of sound waves through vibration of bones in the SKULL to the inner ear (COCHLEA). By using bone conduction stimulation and by bypassing any OUTER EAR or MIDDLE EAR abnormalities, hearing thresholds of the cochlea can be determined. Bone conduction hearing differs from normal hearing which is based on air conduction stimulation via the EAR CANAL and the TYMPANIC MEMBRANE.Temporal Bone: Either of a pair of compound bones forming the lateral (left and right) surfaces and base of the skull which contains the organs of hearing. It is a large bone formed by the fusion of parts: the squamous (the flattened anterior-superior part), the tympanic (the curved anterior-inferior part), the mastoid (the irregular posterior portion), and the petrous (the part at the base of the skull).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.Tongue: A muscular organ in the mouth that is covered with pink tissue called mucosa, tiny bumps called papillae, and thousands of taste buds. The tongue is anchored to the mouth and is vital for chewing, swallowing, and for speech.Nigeria: A republic in western Africa, south of NIGER between BENIN and CAMEROON. Its capital is Abuja.Taste Buds: Small sensory organs which contain gustatory receptor cells, basal cells, and supporting cells. Taste buds in humans are found in the epithelia of the tongue, palate, and pharynx. They are innervated by the CHORDA TYMPANI NERVE (a branch of the facial nerve) and the GLOSSOPHARYNGEAL NERVE.Carcinoma, Squamous Cell: A carcinoma derived from stratified SQUAMOUS EPITHELIAL CELLS. It may also occur in sites where glandular or columnar epithelium is normally present. (From Stedman, 25th ed)Tongue Neoplasms: Tumors or cancer of the TONGUE.Taste: The ability to detect chemicals through gustatory receptors in the mouth, including those on the TONGUE; the PALATE; the PHARYNX; and the EPIGLOTTIS.Abortion, Septic: Any type of abortion, induced or spontaneous, that is associated with infection of the UTERUS and its appendages. It is characterized by FEVER, uterine tenderness, and foul discharge.

Multiple dural arteriovenous shunts in a 5-year-old boy. (1/170)

We describe a rare case of multiple dural arteriovenous shunts (DAVSs) in a 5-year-old boy. MR imaging performed at 1 year of age showed only a dilated anterior part of the superior sagittal sinus; however, angiography at 5 years of age revealed an infantile-type DAVS there and two other DAVSs of the adult type. The pathophysiological evolution of DAVSs in children and their treatment strategies are discussed.  (+info)

Variant arteriovenous fistula of the superior sagittal sinus--case report. (2/170)

A 57-year-old male presented with a rare variant of dural arteriovenous fistula, located in the wall of an unobstructed superior sagittal sinus. Drainage occurred through a cortical vein no longer connected to its parent sinus, which filled up a cluster of transmedullary running veins, one of which was the presumed site of hemorrhage. Arterial blood was supplied via the external carotid artery branches. This type of fistula seriously increases the risk of hemorrhage in the patient and therefore requires complete obliteration. Attempts to embolize the fistula failed. The draining vein was isolated and coagulated resulting in permanent occlusion of the fistula. The fistula probably developed through a process of thrombophlebitis and revascularization via arterioles of the vein rather than previous occlusion of the sinus.  (+info)

Cavernous sinus and inferior petrosal sinus flow signal on three-dimensional time-of-flight MR angiography. (3/170)

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)

Regions of interest in the venous sinuses as input functions for quantitative PET. (4/170)

As clinical PET becomes increasingly available, quantitative methods that are feasible in busy clinical settings are becoming necessary. We investigated the use of intracranial blood pools as sources of an input function for quantitative PET. METHODS: We studied 25 patients after the intravenous injection of [18F]6-fluoro-L-m-tyrosine and compared sampled blood time-activity curves with those obtained in small regions of interest (ROIs) defined in the blood pools visible in the PET images. Because of the comparatively large dimensions of the blood pool at the confluence of the superior sagittal, straight and transverse sinuses, a venous ROI input function was chosen for further analysis. We applied simple corrections to the ROI-derived time-activity curves, deriving expressions for partial volume, spillover and partition of tracer between plasma and red blood cells. The results of graphic and compartmental analysis using both sampled [Cs(t)] and ROI [Cr(t)] venous input functions for each patient were compared. We also used an analytic approach to examine possible differences between venous and arterial input functions in the cerebral circulation. RESULTS: Cr(t) peaked significantly earlier and higher than Cs(t) in this patient population, although the total integral under the curves did not differ significantly. We report some apparent differences in the results of modeling using the two input functions; however, neither the graphically determined influx constant, Ki, nor the model parameter that reflects presynaptic dopaminergic metabolism, k3, differed significantly between the two methods. The analytic results suggest that the venous ROI input function may be closer to the arterial supply of radiotracer to the brain than arterialized venous blood, at least in some patient populations. CONCLUSION: We present a simple method of obtaining an input function for PET that is applicable to a wide range of tracers and quantitative methods and is feasible for diagnostic PET imaging.  (+info)

Skull metastasis of Ewing's sarcoma--three case reports. (5/170)

Three cases of skull metastasis of Ewing's sarcoma were treated. The metastatic lesion was located at the midline of the skull above the superior sagittal sinus in all cases. Surgery was performed in two patients with solitary skull lesions involving short segments of the superior sagittal sinus without remarkable systemic metastasis, resulting in good outcome. The third patient had extensive, multiple tumors involving the superior sagittal sinus which could not be excised, and died due to intracranial hypertension. The surgical indication for skull metastasis of Ewing's sarcoma depends on the location and length of the involved superior sagittal sinus, and general condition.  (+info)

Absent vestibulo-ocular reflexes and acute supratentorial lesions. (6/170)

Loss of vestibulo-ocular reflexes occurred in two patients with acute supratentorial lesions who received therapeutic doses of anticonvulsant drugs. There was no clinical or angiographic evidence of focal brain-stem damage. Absence of vestibulo-ocular reflexes is attributed to a combination of acute cerebral damage and anticonvulsant drugs. The loss of these reflexes in patients with acute cerebral lesions cannot be interpreted as evidence of irreversible brain-stem injury.  (+info)

Scalp vein detected using internal carotid angiography that did not result in venous sinus compromise. (7/170)

We present an unusual case of a scalp vein detected by using angiography of the internal carotid artery. The vein arose from the superior sagittal sinus and drained into the deep posterior cervical vein via the parietal emissary vein. This scalp vein may be a collateral pathway for venous sinuses; however, the patient had no evidence of venous sinus occlusive disease or intracranial hypertension.  (+info)

Sigmoid sinus thrombosis after mild closed head injury in an infant: diagnosis by magnetic resonance imaging in the acute phase--case report. (8/170)

Intracranial sinus thrombosis following a mild closed head injury without a skull fracture or intracranial hematoma is extremely rare. A 23-month-old girl presented with vomiting and gait ataxia 1 day after occipital trauma. Computed tomography revealed a slightly increased density area in the region of the left sigmoid sinus. T1-weighted magnetic resonance (MR) imaging demonstrated an isointense area in the left sigmoid sinus and T2-weighted imaging showed a hyperintense area reflecting the characteristics of oxyhemoglobin. MR angiography and cerebral angiography indicated occlusion of the left sigmoid sinus. After 4 days of conservative treatment, her symptoms subsided completely. Follow-up MR angiography and cerebral angiography showed recanalization of the sigmoid sinus. The MR images and MR angiograms were useful for both early diagnosis and follow-up. Treatment should reflect the severity of individual cases, and early diagnosis will help achieve a good outcome.  (+info)

The emissary veins connect the extracranial venous system with the intracranial venous sinuses. They connect the veins outside the cranium to the venous sinuses inside the cranium. They drain from the scalp, through the skull, into the larger meningeal veins and dural venous sinuses. They are common in children. Emissary veins have an important role in selective cooling of the head. They also serve as routes where infections are carried into the cranial cavity from the extracranial veins to the intracranial veins. There are several types of emissary veins including posterior condyloid, mastoid, occipital and parietal emissary vein. There are also emissary veins passing through the foramen ovale, jugular foramen, foramen lacerum, and hypoglossal canal. Because the emissary veins are valveless, they are an important part in selective brain cooling through bidirectional flow of cooler blood from the evaporating surface of the head. In general, blood flow is from external to internal but the flow ...

The dural venous sinuses are the meningeal ducts or conduits, into which the venous blood from the cerebral veins flows. Located in the dura mater of the meninges, just over the brain surface, their function is to drain the oxygen-depleted blood, which comes from the brain via de cerebral veins, and excess cerobrospinal fluid into the internal jugular vein. There are several dural sinuses in the meninges; they are: superior sagittal sinus, inferior sagittal sinus, straight sinus, occipital sinus, sphenoparietal sinus, cavernous sinuses, confluence of sinuses, superior petrosal sinus, inferior petrosal sinus, transverse sinus, and sigmoid sinus. ...

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 ...

In cases of advanced-stage temporal bone carcinoma, both extensive resections and high-dose irradiation are recommended (6). Although the prognosis of a patient with a T4/stage 4 lesion is grim, survival is better when clear surgical margins can be achieved (5). When an individual situation is assessed, the justified use of radical surgery must be weighted against potential morbidities that may result from facial nerve or ICA resection or the need to sacrifice the dominant sigmoid sinus, as in the present case.. If a dural sinus is completely occluded because of tumor invasion, adequate venous collaterals have developed and the affected sinus can be excised without ensuing venous complications (7). If the affected sinus is still patent, however, the risk of sinus occlusion is high, especially in the posterior two-thirds of the superior sagittal sinus and the dominant transverse or sigmoid sinus; this situation entails the risk of intracranial hypertension and venous infarction (3, 4, 7). ...

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 ...
Cerebral venous sinus thrombosis (CVST) is the presence of acute thrombosis (a blood clot) in the dural venous sinuses, which drain blood from the brain. Symptoms may include headache, abnormal vision, any of the symptoms of stroke such as weakness of the face and limbs on one side of the body, and seizures. The diagnosis is usually by computed tomography (CT/CAT scan) or magnetic resonance imaging (MRI) employing radiocontrast to demonstrate obstruction of the venous sinuses by thrombus. Treatment is with anticoagulants (medication that suppresses blood clotting), and rarely thrombolysis (enzymatic destruction of the blood clot). Given that there is usually an underlying cause for the disease, tests may be performed to look for these. The disease may be complicated by raised intracranial pressure, which may warrant surgical intervention such as the placement of a shunt. Nine in ten people with sinus thrombosis have a headache; this tends to worsen over the period of several days, but may also ...

Intracranial complications of sinusitis are rare but life threatening. We present a case of a 17-year-old woman with sinusitis who deteriorated over the course of 12 days from subdural empyema and global purulent cerebral venous sinus thrombosis. The patient was managed with surgery and mechanical thrombectomy utilizing a novel stent anchor with mobile aspiration technique, in which a Trevo stent retriever (Stryker) was anchored in the superior sagittal sinus (SSS) while a 5 MAX ACE reperfusion catheter (Penumbra) was passed back and forth from the SSS to the sigmoid sinus with resultant dramatic improvement in venous outflow. The patient was extubated on postoperative day 3 and was discharged with minimal lower extremity weakness on postoperative day 11. This is the first report using the Trevo stent retriever for sinus thrombosis. It is important to keep these rare complications in mind when evaluating patients with oral and facial infections. ...
... occurs when a blood clot forms in the brains venous sinuses. This prevents blood from draining out of the brain. As a result, blood cells may break and leak blood into the brain tissues, forming a hemorrhage. This chain of events is part of a stroke that can occur in adults and children of all ages.
Cerebral venous sinus thrombosis (CVST) is a rare clinicopathological entity. The incidence of CVST in children and neonates has been reported to be as high as 7 cases per million people, whereas in adults the incidence is 3-4 cases per million. The predisposing factors to this condition are mainly genetic and acquired prothrombotic states and infection. The clinical picture of CVST is nonspecific, highly variable, and can mimic several other clinical conditions. Diagnosis of CVST is established with the implementation of neuroimaging studies, especially MR imaging and venography. Identification and elimination of the underlying cause, anticoagulation, proper management of intracranial hypertension, and anticonvulsant prophylaxis constitute cornerstones of CVST treatment. Newer treatment strategies such as endovascular thrombolysis and decompressive craniectomy have been recently used in the treatment of patients with CVST with variable success rates. Further clinical research must be performed to
A 52-year-old man with a history of factor V Leiden thrombophilia, persistent headaches and papilloedema presented with worsening vision and confusion. MRI and MR angiography of the brain at the time of this presentation showed findings concerning for transverse sinus thrombosis and an associated dural arteriovenous fistula. Dural venous sinus thrombosis can lead to the formation of a dural arteriovenous fistula, which must be considered in the differential diagnosis for intracranial hypertension in patients with thrombophilia. ...
Cerebral venous sinus thrombosis (CVST) usually is taken care of by medical management or neuro-interventional vascular techniques. Some cases of CVST may take a malignant course if the intracranial pressure increases excessively. This increase in pressure is because of oedema in brain tissue due to impediment in venous return and/or intracerebral haemorrhage. Neurosurgical experience has shown remarkable recovery in these moribund patients if appropriate surgical intervention is done within reasonable time. Emergent decompressive craniotomy or other neurosurgical interventions are the only appropriate treatment in these malignant forms of CVST to prevent mortality and severe morbidity.
Cerebral venous sinus thrombosis in children is increasingly recognized as diagnostic tools and clinical awareness has improved. It is a multifactorial disease where prothrombotic risk factors and predisposing clinical conditions usually in combination constitute the underlying etiology. Clinical features range from headache, seizures to comatose state. Although symptomatic treatment involving control of infections, seizures and intracranial hypertension is uniform, use of anticoagulation and local thrombolytic therapy is still controversial. Morbidity and mortality can be significant and long-term neurological sequelae include developmental delay, sensorimotor and visual deficits and epilepsy.
Dural venous sinus thrombosis is a rare and potentially devastating disease. Several predisposing factors exist, including oral contraceptive therapy and colitis. First-line therapy consists of systemic anticoagulation. If first-line therapies fail, more aggressive endovascular therapies may be performed. We report our initial experience with the Solitaire FR device for treatment of refractory symptomatic dural venous sinus thrombosis.. ...

AU - Teitelbaum, G. P.. AU - Hieshima, G. B.. PY - 1994. Y1 - 1994. N2 - PURPOSE: To gain a preliminary understanding of the role of thrombolytic therapy for the thrombosed dural sinus, we retrospectively reviewed our initial experience. METHODS: Seven patients, ages 25 to 71, who presented with symptomatic dural sinus thrombosis and who failed a trial of medical therapy were treated with direct infusion of urokinase into the thrombosed sinus. Patients received urokinase doses ranging from 20 000 to 150 000 U/h with a mean infusion time of 163 hours (range 88 to 244 hours). RESULTS: Patency of the affected dural sinus was achieved with antegrade flow in all patients. Six patients either improved neurologically over their prethrombolysis state or were healthy after thrombolysis; one of them required ...
In many intracranial disease states, monitoring of intracranial pressure (ICP) is essential to evaluate response to the therapeutic measures as well as estimation of prognosis. Although, direct estimation of ICP is reliable, it is invasive and not possible in all patients. Transcranial Doppler (TCD) ultrasonography is a bedside and noninvasive technique that provides reliable and real-time information about cerebral hemodynamics. We present a case of extensive and progressive cerebral venous sinus thrombosis in which TCD served as an excellent tool for monitoring ICP and the serial observations correlated closely with clinical status and ophthalmological findings.
The diagnosis of CVST has traditionally been made with conventional angiography (DSA).13,19 More recently, DSA has been superseded by MR imaging techniques as the method of choice. MR imaging with MR venography is now commonly considered the noninvasive "gold standard" in diagnosing thrombosis of the cerebral venous sinuses2,5,7,8,20-23 and also dominates the diagnostic arms in large international trials.6 However, because CT is still the technique of choice to rule out intracranial hemorrhage in most institutions, it is tempting to assess a CVST by using the same technique. Therefore, we propose MDCTA as an alternative diagnostic measure in CVST, which is faster, more widely accessible, and more cost-effective than MR imaging.. With the development of helical CT technology, CTA offered a new imaging technique to visualize the cerebral vascular circulation. CTA allowed the visualization of the cerebral venous structures10,11,24-27 and has been shown to have a high sensitivity for depicting the ...
Venous thrombosis may occur in any or all of the following venous structures: the venous sinuses, superficial cortical veins, or the deep venous system. Typically, superficial cortical vein thrombosis is only seen in the seen in the setting of venous sinus thrombosis, and thrombosis of the deep venous system is relatively rare (albeit very serious). Approximately 1% of all strokes occur secondary to venous sinus thrombosis, and the most frequently thrombosed sinuses are the superior sagittal sinus, followed by the transverse, sigmoid and cavernous sinuses. There are numerous conditions associated with venous sinus thromboses and broadly speaking, these tend to be divided into septic or non-septic etiologies. One fourth of cases are of unknown cause. It is common for hemorrhage to be present within areas of venous infarction, whereas it is relatively uncommon to occur with arterial occlusion and infarction. In general, hemorrhagic cerebral infarctions are classified as primary or secondary with ...
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 ...

Our study shows important differences between women and men with CVST and between women with and without GSRF, mostly the use of oral contraceptives. The most conspicuous finding is the far better prognosis of women, which is exclusively caused by a substantially better outcome in female patients with GSRF. Previous retrospective studies reported that CVST in pregnant women has a relatively favorable prognosis.15,17 These results are now confirmed in a large, prospective cohort study and extended to women with all GSRF.. The ISCVT is, to date, the largest prospective cohort study on CVST.3 Participating centers included hospitals from all over the world and investigators committed themselves to include data on consecutive patients. Furthermore, CVST was confirmed in all patients using standard radiological techniques and completeness of follow-up data was high. For these reasons, the data presented in this study are likely to be representative of CVST in general. It must be noted, however, that ...

Well, it turns out I was wrong. There was a family standing with their daughter and both my husband and I noticed that they were speaking English. Once we went into the hall, I noticed the mother looking our way several times, as if she knew us. She finally came over to us and called my husband by his name. It took us a minute or two, but we realized that not only did we know one another, but we both had quite a history with her. She had been on Shlichut (emissary sabbatical year) with her parents in our fair city of Toronto back when I was about 11 years old. She, stuck in a strange city unable to speak a word of English, struck up a warm and meaningful friendship with my husband who was about 14 at the time, and while she helped him learn Hebrew, he eased her transition into the city and the community. And if that wasnt enough, it turned out that her family were distant cousins of mine from my grandmothers side. I actually remember having them over for dinner. Whats funny is that they now ...

Two cases of complete sagittal sinus occlusion with multiple brain hemorrhages, elevated intracranial pressure, and disseminated intravascular coagulation are described. These patients were successfully managed using pentobarbital-induced coma to ameliorate intracranial pressure elevation. This therapy was combined with monitoring of intracranial pressure and intermittent drainage of cerebrospinal fluid to further control intracranial pressure elevations. Thrombus and coagulopathy resolved with pentobarbital alone in one patient and after pentobarbital plus heparin therapy in the second patient. It is suggested that cases of severe distal sagittal sinus thrombosis with brain hemorrhage and intracranial hypertension may benefit from combined pentobarbital coma and intraventricular drainage. This allows for stabilization of bleeding tendencies before instituting heparin therapy when necessary. Management of sagittal sinus thrombosis with barbiturates or ventricular drainage is best performed in an ...

OBJECTIVE To explore the controversial issue of anticoagulant therapy and indications for surgery in association with severe sinus thrombosis. METHODS During the last 4 years, we have treated three patients with severe sinus thrombosis of the dural sinuses. All three patients received systemic anticoagulant therapy and, after experiencing neurological deterioration, underwent open thrombectomy and local thrombolysis. After the operation, aggressive intensive care was given and included cerebral perfusion monitoring, barbiturate administration, hyperventilation, and osmotherapy. The treatment was guided by repeated neuroradiological investigations. RESULTS All three patients returned to their normal lives. CONCLUSION Intracranial sinus thrombosis, even in the worst neurological state, should be treated aggressively. A cornerstone in treatment is systemic anticoagulant therapy and repeated neuroradiological studies. When, despite adequate anticoagulant therapy and intensive care, neurological

Case: A 56 year old man presented with new onset headaches with visual symptoms. Physical examination was normal apart from asymmetrical papilledema and reduced visual acuity 6/9 bilaterally. CSF opening pressure was 26 cm H2O. CTV showed partially recanalised thrombosis in the superior sagittal sinus and the right sigmoid and transverse sinuses which appeared chronic. His headaches initially improved with propranolol but he continued to complain of visual symptoms; repeat CSF opening pressure was 31 cm H2O and repeat CTV was reported as, more occlusive. He was therefore anti-coagulated and treated with acetazolamide.. Six weeks after starting treatment, ophthalmological assessment found worsening visual fields despite reduction in disc swelling on OCT. CSF pressure remained elevated at 30 cm H2O. Repeat CTV and 4D CTA identified a type IIB occipital dural AV fistula around the thrombosed venous sinuses, causing occipital lobe congestion; the likely cause of the visual field defects.. The ...

TY - JOUR. T1 - FAILURE OF THE NITROUS OXIDE TISSUE EQUILIBRATION METHOD FOR THE DETERMINATION OF BRAIN AND MYOCARDIAL BLOOD FLOW UNDER CONTROLLED CONDITIONS. AU - Reid, Michael A.. AU - Runciman, William B.. AU - McLean, Colin F.. AU - Mather, Laurence E.. PY - 1992. Y1 - 1992. N2 - 1. Two adult merino ewes were prepared with intravascular cannule for sampling aortic root blood, sagittal sinus blood and coronary sinus blood. 2. One week after preparation the animals were anaesthetized then ventilated with a gas mixture containing 10% nitrous oxide (N2O) for 60 min. Serial measurements of brain and myocardial blood flow were made using the N2O tissue equilibration method of Kety and Schmidt. 3. N2O failed to achieve matching arteriovenous blood concentration equality and saturation of the relevant tissues. Valid use of the Kety‐Schmidt method, therefore, could not be confirmed. 4. Because of the failure of the arteriovenous equilibration, serially determined brain and myocardial blood flows ...
L: The loose areolar connective tissue layer provides an easy plane of separation between the upper three layers and the pericranium. In scalping the scalp is torn off through this layer. It also provides a plane of access in craniofacial surgery and neurosurgery. This layer is sometimes referred to as the "Danger Zone" because of the ease by which infectious agents can spread through it to emissary veins which then drain into the cranium. The loose areolar tissue in this layer is made up of random collagen I bundles, collagen III and is highly vascular and cellular. It will also be rich in glycosaminoglycans (GAGs) and will be constituted of more matrix than fibers ...

While searching for T-cell pathways in and out of the meninges, the researchers found functional lymphatic vessels lining the dural sinuses of dissected mouse brain meninges. The dural sinuses drain blood from both internal and external veins in the brain into the internal jugular veins. The identified structures expressed all of the molecular hallmarks of lymphatic endothelial cells (eg, expression of the main transcription factor of these cell types, Prox1), were able to carry both fluid (determined by injection of fluorescein and a fluorescent tracer dye) and immune cells (using immunohistochemistry) from the cerebrospinal fluid (CSF), and were connected to the deep cervical lymph nodes.. The authors also subsequently examined autopsy specimens of human dura, including the superior sagittal sinus. They identified a potentially similar lymphatic structure in human dura, but further studies are needed to assess and characterize the location and organization of meningeal lymphatics in the human ...

see Venous infarction. Venous air embolism (VAE) during an elective craniotomy for parasagittal meningioma resection. The surgery was done in the supine position with slightly elevated head position. VAE was provisionally diagnosed by sudden decreased in the end tidal carbon dioxide pressure from 34 to 18 mmHg, followed by marked hypotension and atrial fibrillation. Prompt central venous blood aspiration, aggressive resuscitation and inotropic support managed to stabilize the patient. Post operatively, he was admitted in neuro intensive care unit and made a good recovery without serious complications 15).. Intraoperative fatal pulmonary embolism 16).. Paraparesis can occur as a primary presentation of brain pathology at the motor strip along the parasagittal region. It could also occur as a neurological complication especially following resection of parasagittal meningioma with infiltration of the superior sagittal sinus (SSS). We report a case of a complete paraparesis immediately following ...
New daily persistent headache (NDPH) is a subtype of chronic daily headache. It is bilateral, has a pressing/tightning (non-pulsing) quality, is mild to moderate in intensity, and is not aggravated by routine physical activity. Primary headache disorders are those for which there is no underlying secondary cause that can be identified. As with Migraine disease and some other headache disorders, there are several secondary conditions that can mimic NDPH, so they must be ruled out before a diagnosis of New Daily Persistent Headache can be confirmed. Two conditions in particular that must be ruled out are spontaneous cerebrospinal fluid (CSF) leak and cerebral venous sinus thrombosis.. If the headache is persistant and localized as it is, an MRI of the brain may be indicated although will probably be of low yield. It may well be a kind of status migrainosis - a self perpetuating migraine headache that needs powerful medication to stop it such as IV infusions of steroids, and DHE ...
