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).

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)

Emissary veins - WikipediaEmissary veins - Wikipedia
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 ...

Dural Venous SinusesDural Venous Sinuses
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. ...

Progress in research on intracranial multiple dural arteriovenous fistulas (Review)Progress in research on intracranial multiple dural arteriovenous fistulas (Review)
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). ...

Cerebral venous sinus thrombosis - WikipediaCerebral venous sinus thrombosis - Wikipedia
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 ...

Cerebral Venous Sinus Thrombosis (CVST)Cerebral Venous Sinus Thrombosis (CVST)
Cerebral venous sinus thrombosis (CVST) 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.

Role of surgery in cerebral venous sinus thrombosis by S. Ather EnamRole of surgery in cerebral venous sinus thrombosis by S. Ather Enam
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.

Caring for cerebral venous sinus thrombosis in children. by Mubashira Hashmi and Mohammad WasayCaring for cerebral venous sinus thrombosis in children. by Mubashira Hashmi and Mohammad Wasay
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.

Several studies have reported significantly increased rates of venous and arterial thromboses in patients with COVID-19 despite administration of standard prophylaxis, particularly among those with severe disease requiring intensive care support.3-5 The presence of venous thromboembolism has been associated with an increased risk of death.4 5 Our centre noted 13 imaging-confirmed thromboembolic events in 12 of a total 352 (3.4%) consecutive patients requiring hospital admission for confirmed COVID-19 (March 9, 2020 to April 26, 2020). This compares with a reported incidence of 2% in H1N1 influenza.6 To date, however, cerebral venous sinus thrombosis has only rarely been reported in the context of COVID-19.7 8 The mechanism responsible for increased risk of thrombosis in COVID-19 is now beginning to be understood.9 10 ACE 2 receptor facilitates cell entry of SARS-CoV-2,11 and is expressed on endothelial cells in multiple organ systems.12 Viral infection of endothelial cells with associated ...

Cerebral venous sinus thrombosis | Deranged PhysiologyCerebral venous sinus thrombosis | Deranged Physiology
Central venous sinus thrombosis (CVT) and venous cerebral infarction are important differentials for the causes of headache or seizure in the young person, particularly in the young woman who is/has recently been pregnant. It is probably the most rare form of stroke, but - when it happens - the patient usually will end up in ICU, and the critical care trainee will probably see more of this than any other specialty. This has come up in Question 26 from the second paper of 2015. Dural sinus thrombosis in that question was associated with pregnancy (as typically they are) and the question could easily be shoved into the O&G section, but the specific information requested from the candidates (outline the management priorities, etc) was more neurological/neurosurgical in nature.

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 ...

Neuroradiology On the Net: gennaio 2008Neuroradiology On the Net: gennaio 2008
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 ...

Stent retriever thrombectomy combined with long‑term local thrombolysis for severe hemorrhagic cerebral venous sinus thrombosisStent retriever thrombectomy combined with long‑term local thrombolysis for severe hemorrhagic cerebral venous sinus thrombosis
CVST is a rare disease with a potentially fatal outcome. During recent decades, its incidence has markedly increased, which may be attributed to advances in imaging techniques (15). However, CVST may not be timely diagnosed, as its clinical presentations are atypical and non-specific (2). Non-contrast CT scan is only able to reveal indirect signs of CVST and has low sensitivity and specificity (16). A number of the patients in the present study were not accurately diagnosed with CVST at their primary hospital; they were initially misdiagnosed, e.g. with postpartum reaction, fatigue or simple diarrhea, which led to rapid aggravation of the symptoms, ICH and life-threatening complications due to the absence of specific treatment. The timely and correct treatment for SH-CVST remains controversial. Systemically administered anticoagulation with heparin (unfractionated or LMWH) is the standard first-line treatment for CVST, even in patients with an ICH at baseline (17). However, a subset of patients ...

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 ...

We included two small trials involving 79 patients. One trial (20 patients) examined the efficacy of intravenous, adjusted dose unfractionated heparin. The other trial (59 patients) examined high dose, body weight adjusted, subcutaneous, low-molecular weight heparin (nadroparin). Anticoagulant therapy was associated with a pooled relative risk of death of 0.33 (95% confidence interval (CI) 0.08 to 1.21) and of death or dependency of 0.46 (95% CI 0.16 to 1.31). The absolute reduction in the risk of death or dependency was 13% (95% CI 30% to -3%). No new symptomatic intracerebral haemorrhages were observed. One major gastro-intestinal haemorrhage occurred after anticoagulant treatment. Two control patients (placebo) had a diagnosis of probable pulmonary embolism (one fatal).. ...

OBJECTIVE: Dural sinus thrombosis (DST) is an uncommon cause of stroke. The safest and most effective therapy for DST has not been conclusively identified.. METHODS: A retrospective chart review of data for 31 patients who were treated for DST at our institution between 1992 and 2001 was performed. Four treatment strategies were identified, i.e., 1). medical observation only, 2). systemic anticoagulation (AC) therapy with heparin, 3). endovascular chemical thrombolysis with urokinase or tissue plasminogen activator and concurrent systemic AC therapy, and 4). mechanical endovascular clot thrombolysis with concurrent systemic AC therapy. Complications and clinical outcomes were assessed for each group.. RESULTS: Patients treated solely with medical observation fared the worst; four of five patients experienced intracranial hemorrhagic complications, and only two of five exhibited clinical improvement. Patients who received systemic AC therapy experienced no hemorrhagic complications, even when ...

Sensitization of meningeal sensory neurons and the origin of headaches | NatureSensitization of meningeal sensory neurons and the origin of headaches | Nature
THE headaches that accompany certain intracranial pathologies (such as meningitis, subarachnoid haemorrhage and tumour) have been considered to result from mechanical or chemical stimulation of pain-sensitive structures of the intracranial meninges1,2. Although the recurrent headache of migraine is of unknown origin and is not accompanied by an identifiable pathology, it shares with intracranial headaches features that suggest an exaggerated intracranial mechanosensitivity (worsening of the pain by coughing, breath-holding or sudden head movement1,3). One possible basis for such symptoms would be a sensitization of meningeal afferents to mechanical stimuli. Previous studies of neuronal responses to meningeal stimulation have focused primarily on cells in the central portion of the trigeminal pathway, and have not investigated the possible occurrence of sensitization4-12. We have recorded the activity of primary afferent neurons in the rat trigeminal ganglion that innervate the dural venous sinuses.

UK records 30 blood clot cases after AstraZeneca jabs - Health ReportersUK records 30 blood clot cases after AstraZeneca jabs - Health Reporters
By Haruna Gimba. Thirty cases of rare blood clotting have been recorded in the United Kingdom among more than 18 million people who have had the AstraZeneca vaccination, the national medicines regulator said.. The benefits of the vaccines against COVID-19 continue to outweigh any risks, the Medicines and Healthcare products Regulatory Agency (MHRA) said, urging the public to keep taking the vaccine.. Up to March 24, 22 reports of cerebral venous sinus thrombosis (CVST) and eight other thrombosis events with low platelets were logged.. The risk of having this specific type of blood clot is very small, the agency noted.. The number and nature of suspected adverse reactions reported so far are not unusual in comparison to other types of routinely used vaccines, the MHRA online statement said.. However, there were no such reports for the Pfizer/BioNTech vaccine.. The agency said vaccination was the most efficient way to reduce the number of deaths and serious illness from coronavirus..

CDC Press Release issued today, April 13, 2021:. As of April 12, more than 6.8 million doses of the Johnson & Johnson (Janssen ) vaccine have been administered in the U.S. CDC and FDA are reviewing data involving six reported U.S. cases of a rare and severe type of blood clot in individuals after receiving the J&J vaccine. In these cases, a type of blood clot called cerebral venous sinus thrombosis (CVST) was seen in combination with low levels of blood platelets (thrombocytopenia). All six cases occurred among women between the ages of 18 and 48, and symptoms occurred 6 to 13 days after vaccination. Treatment of this specific type of blood clot is different from the treatment that might typically be administered. Usually, an anticoagulant drug called heparin is used to treat blood clots. In this setting, administration of heparin may be dangerous, and alternative treatments need to be given.. CDC will convene a meeting of the Advisory Committee on Immunization Practices (ACIP) on Wednesday to ...

Cerebral Venous and Sinus Thrombosis in Women | StrokeCerebral Venous and Sinus Thrombosis in Women | Stroke
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 ...
