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. ...

The patient presented at 3 months of age with increased head circumference and a bruit over his anterior fontanelle. Diagnostic cerebral angiography confirmed the presence of a large mural-type VoGM. The decision was made to undergo a staged arterial embolization at 4 years of age after developing worsening right-sided hemiparesis. An attempt was made to occlude the posterior choroidal feeding vessel with a large 25 mm × 50 cm coil, followed by a 6 mm × 20 cm coil; however, the high flow of the lesion displaced both coils into the wall of the aneurysmal venous sac. Interval magnetic resonance imaging and angiography revealed partial occlusion of the VoGM at ...

A 37-year-old gravida 3, para 1 pregnant woman was referred to the Maternal Fetal Care Center (MFCC) at Boston Childrens Hospital at 36 weeks gestation for the finding of vein of Galen malformation (VOGM).. The patients pregnancy was complicated by gestational diabetes. Her surgical history was notable for adenoidectomy, a previous cesarean section, and dilation and curettage following a spontaneous abortion. Maternal medications included prenatal vitamins and glyburide. Family history was noncontributory. This pregnancy was planned and naturally conceived. The woman received appropriate prenatal care. Noninvasive prenatal screening showed her to be at low risk and cell-free fetal DNA screening was negative. She had a normal anatomy scan at 20 weeks gestation. Fetal ultrasonography performed at 36 weeks gestation for evaluation of fetal growth demonstrated a prominent rounded vascular structure in the quadrigeminal cistern with turbulent flow consistent with a VOGM. Fetal echocardiography ...

We aimed to analyze the causes and predictors of death during the acute phase of CVT in the International Study on Cerebral Vein and Dural Sinus Thrombosis (ISCVT) to identify preventable or treatable causes. Methods - ISCVT is a multinational, prospective, observational study including 624 patients with CVT occurring between May 1998 and May 2001, in which 27 patients (4.3%) died during the acute phase, 21 (3.4%) within 30 days from symptom onset. Inclusion forms and a questionnaire assessing the causes of death were analyzed. A logistic regression analysis was performed to identify the predictors of death within 30 days from symptom onset of CVT. Results - Median time between onset of symptoms and death was 13 days and between diagnosis and death, 5 days. Causes of death were mainly ...

Using the large data set of this prospective multicenter international study, we described a distinctive clinical presentation of CVT in patients aged ≥65 years. CVT in such elderly patients rarely presents as isolated intracranial hypertension syndrome, but depressed consciousness and altered mental status are common. The prognosis of elderly patients was worse than that of younger patients: only 49% recovered completely, whereas 22% were dependent and 27% had died at the end of follow-up.. Strengths of this study include: (1) large sample size and diversity of participating hospitals in different countries and continents, which diminishes potential inclusion bias; (2) diagnostic confirmation by robust methods in all cases; (3) 98.7% completeness of follow-up. There are, however, some potential limitations: differential effect of age in case ascertainment and previous disability in elderly patients. It is possible that younger subjects reporting of headache were investigated sooner and more ...

One of the major regulators of cerebral venous outflow is posture, due to the gravitational gradient between the cerebral parenchymal veins and the base of the neck (␣30mmHg).2 The authors demonstrate a much larger change in blood flow volume in normal subjects compared to MS patients when the subjects go from a supine to an upright position. They find a change of 128ml/min and 56ml/min for the right and left sides, respectively, for MS patients. But they find a much larger change of 266ml/min and 105ml/min for their normal subjects. This result actually suggests the presence of chronic cerebrospinal venous insufficiency (CCSVI). Possible causes include intra-luminal septum, membrane, and immobile valve affecting the hydrostatic pressure gradient in the upright position. The presence of such blockages in the extracranial and extravertebral cerebral veins has been proven also by using catheter venography, the unquestionable gold standard in medicine.3,4 ...

Venous air embolism is a dreaded condition particularly relevant to the field of nephrology. In the face of a favourable, air-to-blood pressure gradient and an abnormal communication between the atmosphere and the veins, air entrance into the circulation is common and can bring about venous air embolism. These air emboli can migrate to different areas through three major routes: pulmonary circulation, paradoxical embolism and retrograde ascension to the cerebral venous system. The frequent undesirable outcome of this disease entity, despite timely and aggressive treatment, signifies the importance of understanding the underlying pathophysiological mechanism and of the implementation of various preventive measures ...
The dura mater has been cut away so that the left cerebral hemisphere is visible lying inside the arachnoid membrane. The tentorium appears in the lower right part of the view and the transverse sinus is opened along its posterior border. The superior sagittal sinus has been opened by removing a strip of dura from its superficial wall. The superior cerebral veins ascend on the surface of the frontal and parietal lobes to empty into this sinus at various points. A number of anastomoses are present between these veins, none being particularly large in this specimen. In general the superior cerebral veins are divided into anterior and posterior groups. In this case there appear to be several anterior vessels, a group of large veins intermediate in position (overlying the region of the central sulcus) and several posterior veins (not visible in this view ...

Background: Postoperative cerebral venous infarction (POCVI) is not an uncommon complication in cranial surgeries. However, literature is sparse on the epidemiology and management of postoperative venous infarcts. Aims and Objectives: The aim was to study the incidence and clinico-radiological course of POCVI in patients in a tertiary level neurosurgical unit and compare the outcome between pediatric and adult patients following POCVI. Materials and Methods: In this prospective study carried out over an 8 month period, consecutive patients undergoing elective major cranial surgeries were monitored neurologically and with serial computed tomography (CT) of the head for POCVI in the postoperative period. All patients had at least one CT head done within 24 hours of surgery. Diagnosis of hemorrhagic POCVI was based on the presence of subcortical, multifocal hyperdensities with irregular margins and or low density areas in the perioperative fields. Nonhemorrhagic POCVI was diagnosed if CT showed a ...

One hypothesis would be via the stimulation of the parasympathetic afferent or sensory nerve fibres that innervate cerebral veins and venous sinuses. There is an extensive literature on the potential mechanisms of how parasympathetic stimulation, using the vagal nerve, could be anti-inflammatory. I suspect exploring the mechanisms of how venoplasty is anti-inflammatory is academic because the treatment effect is so small and is nowhere close to the effectiveness of licensed DMTs. Why would you have venoplasty if you could be on a more effective DMT?. I hope this will finally be the last we hear about CCSVI. I want to stress when you apply medical philosophical principles, CCSVI is not a disease; it does not fulfil the contemporary definition of being a disease entity. In short, there is not clinicopathological correlate that defines CCSVI as being a disease. A better descriptor for CCSVI would be that it is a meme.

On September 9th, 2010 our little Elliot Justin passed away after being born just one week earlier . When I was 37 weeks pregnant with him, he was diagnosed with an extremely rare birth defect, Vein of Galen Malformation. A vein in his brain had extra arteries coming off of it and the large structure was taxing his heart at an alarming rate. We were told after his first MRI that his chances of survival were very slim. When he was one week old he underwent surgery to block the excess arteries. Elliot sufferred a huge brain bleed during the surgery and passed away the next day.. We continue to treasure and remember the one week we had with Elliot. He was a peaceful and amazing soul. We wish that we could have watched him grow up. He will always be a part of our family, and we miss him as much today as the day that he died.. During Elliots one week with us, he was in Childrens Hospital NICU. The nurses and staff of the NICU were nothing short of amazing. They made it possible for us to hold him, ...

MRA and CTA are considered noninvasive imaging methods to visualize arterial and venous structures with out the need for direct placement of a catheter into a patients vessel of interest. The benefit to the patient is that CTA and MRA may be no more uncomfortable than placement of an IV needle into the arm with the subsequent injection of a peripheral arm vein. MRA and CTA are less expensive than the alternative traditional Xray contrast angiographic study and without the risks of needle placement into a groin vessel with subsequent threading of a catheter into the vessel of interest. MRA, as opposed to CTA and traditional angiography, does not require iodine based contrast agents and is safe for patients with renal insufficiency.. Candidates for these procedures are typically patients with increased risk for intracranial aneurysm, arterial narrowing of vessels of the neck, vascular occlusive disease of the lower extremities, or suspected renal arterial narrowing in patients with uncontrolled ...
The Sons of Horus emissary, Argonis, was dispatched by Maloghurst on behalf of Horus, and he traveled on the storm eagle Sickle Blade. He was accompanied by Prophesius the astropath and Sota-Nul of the Dark Mechanicum, and he sought audience with Perturabo on the Iron Blood to demand why he invaded Tallarn. Perturabo, after revealing his irritation, stated that Tallarn was a valuable route to Terra. Argonis was dismissed, but he did not trust the primarchs word and contacted the Alpha Legion to investigate. After 12 days, the Alpha Legion agent and psyker, Jalen, posed as a serf and met with Argonis. Jalen stated that he did not know why the Iron Warriors were present at Tallarn, but he admitted that the Alpha Legion was on the planet before they arrived. Argonis leaves for the Sightless Warren, not trusting the Alpha Legion forces. During this time, Imperial Infocyte agent Iaeo, of Clade Vanus, follows Argonis and the Alpha Legion agents, interfering when she can to set Horuss forces against ...
The Jewish view on angels is derived from the Hebrew word malach, which means both emissary and angel. Basically, angels are Gcds messengers. Each one is created for a specific task, and ceases to exist when that task is completed. Some angels have ongoing missions and thus exist for eons; other exist for a fleeting moment. The Rambam, based on a careful examination of angelic verses throughout the Torah, organized the types of angels into a ten-level hierarchy. They are, to use a cytology analogy, the messenger RNA in the great cytoplasm of the universe. ...

Chronic cerebrospinal venous insufficiency (CCSVI or CCVI) is a term developed by Italian researcher Paolo Zamboni in 2008 to describe compromised flow of blood in the veins draining the central nervous system. Zamboni hypothesized that it played a role in the cause or development of multiple sclerosis (MS). Zamboni also devised a procedure which was termed by the media as liberation procedure or liberation therapy, involving venoplasty (or stenting) of certain veins in an attempt to improve blood flow. Within the medical community, both the procedure and CCSVI have been met with skepticism. Zambonis first published research was neither blinded nor did it have a comparison group. Zamboni also did not disclose his financial ties to Esaote, the manufacturer of the ultrasound specifically used in CCSVI diagnosis. The liberation procedure has been criticized for possibly resulting in serious complications and deaths while its benefits have not been proven. The United States Food and Drug ...
The incidence of cerebral venous thrombosis (CVT) is increasing, partly due to an improvement in the diagnostic techniques [1]. growing tendency for neurologists to consider them for treatment of CVT. A few case series have been published supporting the security and efficacy of these drugs in CVT cases [8-11]. More recently, the results of one randomized controlled trial (randomized controlled trial of the security and efficacy of dabigatran etexilate vs. dose-adjusted warfarin in patients with cerebral venous thrombosis [RESPECT CVT]) were presented at World Stroke Congress in 2018 [12]. The trial randomized 120 patients to either dabigatran or warfarin and showed no recurrence of venous thrombotic events and a small number of major bleedings in both arms. Before the results of RESPECT CVT were made available, we conducted a multicenter prospective, observational study to evaluate the security of NOACs compared to warfarin in patients with CVT. Data was collected from October 2016 to October ...
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 ...
Two very recent scientific papers have re-opened a debate on a vascular issue, chronic cerebrospinal venous insufficiency (CCSVI), that apparently was sent in a corner by other trials and some Editorial hasty conclusions. The never-ending debate is still open and, perhaps, a one-year truce helped to calm waters and sort out, as by means of a sandbox, the situation from the vascular point of view. Before discussing why these recent papers have widened the path for CCSVI, some mind refreshing is mandatory, since the opinions are spread in all directions and a concise summary may help for those that are newcomers in this issue.... ...

Mironov3 first described 2 cases of selective transvenous embolization of DAVFs, including 1 superior sagittal sinus DAVF and 1 TSS-DAVF. Since then, several cases of intracranial DAVF shunting to a localized venous pouch adjacent to the major dural sinuses have been reported, which can be treated by selective transvenous embolization while preserving the sinus drainage from normal cerebral veins. These are generally thought to be special cases of intracranial DAVF.4 Of 140 cases of TSS-DAVFs, Caragine et al5 described 10 patients with TSS-DAVFs with a fistulous venous channel in a position parallel to the TSS (parallel venous channel). However, we often observed similar parasinusal venous pouches in many cases of intracranial DAVFs in our clinical practice. Piske et al6 investigated cerebral angiography in 40 intracranial DAVFs and found a dural sinus compartment in 12 of the 40 cases (30%). Nine of these cases could be treated by a selective transvenous embolization technique, preserving the ...

Background: We report a case series of cerebral vein thrombosis (CVT) in women who used oral contraceptive pill (OCP) in the Muslims Ramadan and fasting month.Methods: This study was a retrospective case series of 9 patients with diagnosis of CVT, who admitted in the neurology ward of Tohid Hospital of Sanandaj, Iran, in July-August 2014-2015.Results: Patients had no history of thrombosis before. They were treated with oral contraceptive more than 1 month to be able to fast during Ramadan. They did not have other possible risk factors for CVT. A headache was the most common in 9/9 patients (100%) followed by vomiting and vertigo.Conclusion: We found that high rate of CVT in female population during Ramadan indicates that it needs be considered as a specific risk factor and should be considered by healthcare system.
In this study, the diagnostic accuracy of a combined, dynamic and static, contrast-enhanced MRV in CVT was compared with established MR and MRV sequences. Combo-4D MRV demonstrated the highest overall sensitivity (binary test) among the 4 assessed techniques for all thrombosed venous segments, with its overall accuracy (ROC analysis) being superior to T2W and GRE imaging, and equivalent to TOF MRV. Its overall specificity (binary test) was again superior to TOF MRV. Its incomplete overall sensitivity of 76% is most likely related to the inclusion of thrombosed cortical veins that are notoriously difficult to assess on MRV due to their high variability in number, size, and location.6,22 In dural venous sinus thrombosis alone, it showed the highest sensitivity (97%) and specificity (99%) among the 4 assessed techniques. Although only a trend toward superior accuracy was found on ROC analysis between combo-4D MRV (AUC of 0.99) and TOF MRV (AUC of 0.96), a significantly higher sensitivity and ...
SUMMARY Evidence of damage to cerebral vein walls was sought in 70 cases of multiple sclerosis. Seventy control cases were also examined. The multiple sclerosis cases showed venous intramural fibrinoid deposition (7 %), recent haemorrhages (17%), old haemorrhages revealed by haemosiderin deposition (30%), thrombosis (6%) and thickened veins (19%). In all, 41% of all multiple sclerosis cases showed some evidence of vein damage. Occasional control cases showed haemosiderin deposition in the brain but, unlike the multiple sclerosis cases, these were diffuse and almost entirely related to coexistent cardiovascular or cerebrovascular disease. Haemosiderin deposition was common in the substantia nigra and other pigmented nuclei in all cases. It is concluded that the cerebral vein wall in multiple sclerosis is subject to chronic inflammatory damage, which promotes haemorrhage and increased permeability, and constitutes a form of vasculitis ...
INTRODUCTION: Cerebral venous thrombosis (CVT) is still a significant diagnostic and therapeutic challenge, due to its high variability of clinical manifestations and its lack of a clear therapeutic consensus.. SOURCES: A search of the medical literature was made through PubMed using the conjoined terms of CVT and epidemiology (428 results), pathophysiology (504 results), aetiology (2714 results), diagnosis (2802 results), treatment (2173 results) and outcome (648 results). Original and review publications deemed to be useful for this review were selected. Classical and historical works on CVT were also included.. DEVELOPMENT: The present paper reviews the fundamental aspects of the epidemiology, pathophysiology and aetiology of CVT. There is a comparison of the most common initial clinical manifestations along with a description of the most important neuroradiological studies needed to establish a diagnosis, all based on multiple published series. Moreover, in order to serve as an important ...

Of all pituitary adenomas, 6%-10% involve the cavernous sinus and are considered to be invasive. The clinical signs occur late. Cavernous sinus invasion increases the morbidity and mortality associated with surgical procedures. During MR imaging, the absence of invasion can be assumed if a venous compartment is visible between the tumour and the intracavernous internal cerebral artery (ICA).The content of the cavernous sinus is isointense and is interspersed with small foci of an increased signal intensity which correspond to a slow blood flow or the presence of fat; the ICA is easly identifiable because of its characteristic thin walls surrounding a lumen of a low signal intensity, which is reflective of a high-velocity flow void. After adminstration of a gadolinium contrast, the venous compartments are enhanced strongly, and, thus, the depiction of these structures becomes easy. On the other hand, total encasement of the intracavernous ICA is a very specific sign. Alternative criteria have to ...
Inter-rater agreement for CCSVI has never been systematically analysed so far, though scattered information is available from case-control studies. We found an unsatisfactory agreement for the diagnosis of CCSVI with an overall κ of 0.20. For Zambonis five criteria, the agreement was no higher than chance for two criteria (2 and 4), little more than slight for two criteria (3 and 5) and fair for one (criterion 1), according to Landis and Koch s classification.25 Agreement for CCSVI was 0.75 in a study that blindly evaluated 28 participants,19 and 0.79 in another case-control study.11 We found the worst agreement for criteria 2 and 4, whereas it was better for criteria involving a measurement (as for criterion 5) or a direct visualisation of a venous anatomical abnormality (as criterion 3). This seems to indicate that criteria 2 and 4 are more prone to subjective interpretation. Criterion 2 was also the most critical in the study by Tsivgoulis et al,26 together with criterion 5, though their ...
