Congenital arteriovenous malformation involving the VEIN OF GALEN, a large deep vein at the base of the brain. The rush of arterial blood directly into the vein of Galen, without passing through the CAPILLARIES, can overwhelm the heart and lead to CONGESTIVE HEART FAILURE.
Veins draining the cerebrum.
Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital arteriovenous fistula. The lack of blood flow and oxygen in the capillaries can lead to tissue damage in the affected areas.
The vessels carrying blood away from the capillary beds.
Congenital vascular anomalies in the brain characterized by direct communication between an artery and a vein without passing through the CAPILLARIES. The locations and size of the shunts determine the symptoms including HEADACHES; SEIZURES; STROKE; INTRACRANIAL HEMORRHAGES; mass effect; and vascular steal effect.
A group of congenital malformations involving the brainstem, cerebellum, upper spinal cord, and surrounding bony structures. Type II is the most common, and features compression of the medulla and cerebellar tonsils into the upper cervical spinal canal and an associated MENINGOMYELOCELE. Type I features similar, but less severe malformations and is without an associated meningomyelocele. Type III has the features of type II with an additional herniation of the entire cerebellum through the bony defect involving the foramen magnum, forming an ENCEPHALOCELE. Type IV is a form a cerebellar hypoplasia. Clinical manifestations of types I-III include TORTICOLLIS; opisthotonus; HEADACHE; VERTIGO; VOCAL CORD PARALYSIS; APNEA; NYSTAGMUS, CONGENITAL; swallowing difficulties; and ATAXIA.

'Abnormalities, Multiple' is a broad term referring to the presence of two or more structural or functional anomalies in an individual, which may be genetic or environmental in origin, and can affect various systems and organs of the body.
An autosomal recessive disorder of CHOLESTEROL metabolism. It is caused by a deficiency of 7-dehydrocholesterol reductase, the enzyme that converts 7-dehydrocholesterol to cholesterol, leading to an abnormally low plasma cholesterol. This syndrome is characterized by multiple CONGENITAL ABNORMALITIES, growth deficiency, and INTELLECTUAL DISABILITY.
A whiplike motility appendage present on the surface cells. Prokaryote flagella are composed of a protein called FLAGELLIN. Bacteria can have a single flagellum, a tuft at one pole, or multiple flagella covering the entire surface. In eukaryotes, flagella are threadlike protoplasmic extensions used to propel flagellates and sperm. Flagella have the same basic structure as CILIA but are longer in proportion to the cell bearing them and present in much smaller numbers. (From King & Stansfield, A Dictionary of Genetics, 4th ed)

Trans-cranial placement of an amplatzer device to control intractable cardiac failure in an infant with a vein of galen anomaly. A case report. (1/8)

Neonates presenting with intractable cardiac failure due to vein of Galen aneurysmal malformations (VGAMs) rapidly progress to multisystem organ failure and death if left untreated. Currently the only viable treatment option is endovascular embolization. Although intracranial embolization of a neonate is a high-risk procedure, successful treatment can reverse cardiac failure and prevent neurological complications associated with VGAMs. Embolization via the arterial route is thought to have a better outcome than embolization via the venous system. However, multiple transarterial embolizations in different sessions may well be contraindicated in neonates, because repeat access via the femoral artery, carries a risk of arterial trauma which, in turn, can jeopardize lower limbs. With this case study we show that after repeat failure of arterial embolization, the transcranial placement of an Amplatzer PFO occluder (AGA Medical, Plymouth, USA) in the aneurysm can effectively reduce intrafistular pressure and venous outflow velocity. We also propose a mathematical model that can be used to calculate flow velocity through the aneurysm, which, in turn, could be used to aid clinical decision-making. Unlike some conventional techniques, the placement of an Amplatzer occluder does not pose the risk of completely obstructing venous drainage and therefore does not increase the risk of venous breakthrough hemorrhage. We propose this endovascular technique as a treatment option for high risk neonates in need of emergency embolization of VGAMs, where multiple arterial embolizations failed to control the condition sufficiently.  (+info)

Clinics in diagnostic imaging (132). Vein of Galen malformation. (3/8)

A two-day-old, full-term male infant was admitted to the neonatal intensive care unit with heart failure. He was found to be non-dysmorphic, with no clinical evidence of sepsis. Physical examination was significant for hepatomegaly, active precordium, pansystolic murmur and hypotension requiring ionotropic support. A cranial bruit was detected on auscultation. Chest radiography revealed cardiomegaly and pulmonary oedema due to heart failure. Electrocardiogram and two-dimensional echocardiography were normal. Magnetic resonance imaging of the brain showed a large vein of Galen malformation, extensive cerebral ischaemia and multiple cerebral infarcts. This case illustrates the importance of auscultation of the cranium to rule out vein of Galen malformation, a potential cause of high-output cardiac failure in neonates in the absence of other common causes of heart failure.  (+info)

Transarterial embolisation with Guglielmi detachable coils in an infant with a vein of Galen aneurysmal malformation. (7/8)

Vein of Galen aneurysmal malformation is a rare entity in the paediatric population. However, it is being recognised with increasing frequency due to better diagnostic techniques. Neonates usually present with congestive heart failure, while in older infants and children it tends to manifest with seizures, hydrocephalus, intracerebral or subarachnoid haemorrhages. We present a case of ruptured vein of Galen aneurysmal malformation in a 3-month-old baby boy treated by transarterial embolisation using Guglielmi detachable coils.  (+info)

A Vein of Galen Malformation (VOGM) is a rare type of congenital vascular anomaly, specifically an arteriovenous malformation (AVM), which affects the cerebral circulation. This complex tangle of abnormal blood vessels develops around or near the Vein of Galen, a fetal vessel that normally closes and transforms into a small venous structure in the brain after birth.

In VOGM, the Vein of Galen remains dilated due to the direct feeding from arteries, usually from the choroidal or cerebral arterial systems. This results in an abnormal connection (shunt) between the arterial and venous circulations, causing high-flow, high-pressure blood flow through the Vein of Galen and into the heart.

VOGMs can be classified as either "mascular" or "extracardiac," depending on whether they involve only the Vein of Galen (mascular) or if they also include other structures like the straight sinus, torcular Herophili, or other venous sinuses (extracardiac).

VOGMs can lead to various clinical presentations, including congestive heart failure, hydrocephalus, developmental delays, seizures, and neurological deficits. Symptoms may appear early in infancy or even prenatally, as the increased blood flow through the Vein of Galen puts a strain on the heart and can lead to high output cardiac failure.

Diagnosis is often made using imaging techniques such as ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), or angiography. Treatment options include endovascular embolization, surgical intervention, or a combination of both, depending on the severity and location of the malformation.

Cerebral veins are the blood vessels that carry deoxygenated blood from the brain to the dural venous sinuses, which are located between the layers of tissue covering the brain. The largest cerebral vein is the superior sagittal sinus, which runs along the top of the brain. Other major cerebral veins include the straight sinus, transverse sinus, sigmoid sinus, and cavernous sinus. These veins receive blood from smaller veins called venules that drain the surface and deep structures of the brain. The cerebral veins play an important role in maintaining normal circulation and pressure within the brain.

Arteriovenous malformations (AVMs) are abnormal tangles of blood vessels that directly connect arteries and veins, bypassing the capillary system. This results in a high-flow and high-pressure circulation in the affected area. AVMs can occur anywhere in the body but are most common in the brain and spine. They can vary in size and may cause symptoms such as headaches, seizures, or bleeding in the brain. In some cases, AVMs may not cause any symptoms and may only be discovered during imaging tests for other conditions. Treatment options include surgery, radiation therapy, or embolization to reduce the flow of blood through the malformation and prevent complications.

Veins are blood vessels that carry deoxygenated blood from the tissues back to the heart. They have a lower pressure than arteries and contain valves to prevent the backflow of blood. Veins have a thin, flexible wall with a larger lumen compared to arteries, allowing them to accommodate more blood volume. The color of veins is often blue or green due to the absorption characteristics of light and the reduced oxygen content in the blood they carry.

Intracranial arteriovenous malformations (AVMs) are abnormal, tangled connections between the arteries and veins in the brain. These connections bypass the capillary system, which can lead to high-flow shunting and potential complications such as hemorrhage, stroke, or neurological deficits. AVMs are congenital conditions, meaning they are present at birth, although symptoms may not appear until later in life. They are relatively rare, affecting approximately 0.1% of the population. Treatment options for AVMs include surgery, radiation therapy, and endovascular embolization, depending on the size, location, and specific characteristics of the malformation.

Arnold-Chiari malformation is a structural abnormality of the brain and skull base, specifically the cerebellum and brainstem. It is characterized by the descent of the cerebellar tonsils and sometimes parts of the brainstem through the foramen magnum (the opening at the base of the skull) into the upper spinal canal. This can cause pressure on the brainstem and cerebellum, potentially leading to a range of symptoms such as headaches, neck pain, unsteady gait, swallowing difficulties, hearing or balance problems, and in severe cases, neurological deficits. There are four types of Arnold-Chiari malformations, with type I being the most common and least severe form. Types II, III, and IV are progressively more severe and involve varying degrees of hindbrain herniation and associated neural tissue damage. Surgical intervention is often required to alleviate symptoms and prevent further neurological deterioration.

P120 GTPase activating protein (GAP) is not a commonly used medical term, and it may be more accurate to describe it as a term from cell biology. However, I can still provide you with some information about this protein.

P120 GTPase activating protein is a type of protein that functions as a negative regulator of RhoA, Rac, and Cdc42, which are members of the Rho family of GTPases. These GTPases play crucial roles in regulating various cellular processes such as cell adhesion, migration, proliferation, and differentiation.

P120 GAP contains a conserved catalytic domain that promotes the hydrolysis of GTP to GDP, thereby turning off RhoA, Rac, and Cdc42 signaling pathways. P120 GAP has been implicated in various cellular processes, including the regulation of cadherin-based adhesion complexes, cell migration, and tumor suppression.

Mutations in the p120 GAP gene have been associated with several types of cancer, including colon, lung, and breast cancer, suggesting that this protein may play a critical role in preventing tumor development and progression.

A syndrome, in medical terms, is a set of symptoms that collectively indicate or characterize a disease, disorder, or underlying pathological process. It's essentially a collection of signs and/or symptoms that frequently occur together and can suggest a particular cause or condition, even though the exact physiological mechanisms might not be fully understood.

For example, Down syndrome is characterized by specific physical features, cognitive delays, and other developmental issues resulting from an extra copy of chromosome 21. Similarly, metabolic syndromes like diabetes mellitus type 2 involve a group of risk factors such as obesity, high blood pressure, high blood sugar, and abnormal cholesterol or triglyceride levels that collectively increase the risk of heart disease, stroke, and diabetes.

It's important to note that a syndrome is not a specific diagnosis; rather, it's a pattern of symptoms that can help guide further diagnostic evaluation and management.

'Abnormalities, Multiple' is a broad term that refers to the presence of two or more structural or functional anomalies in an individual. These abnormalities can be present at birth (congenital) or can develop later in life (acquired). They can affect various organs and systems of the body and can vary greatly in severity and impact on a person's health and well-being.

Multiple abnormalities can occur due to genetic factors, environmental influences, or a combination of both. Chromosomal abnormalities, gene mutations, exposure to teratogens (substances that cause birth defects), and maternal infections during pregnancy are some of the common causes of multiple congenital abnormalities.

Examples of multiple congenital abnormalities include Down syndrome, Turner syndrome, and VATER/VACTERL association. Acquired multiple abnormalities can result from conditions such as trauma, infection, degenerative diseases, or cancer.

The medical evaluation and management of individuals with multiple abnormalities depend on the specific abnormalities present and their impact on the individual's health and functioning. A multidisciplinary team of healthcare professionals is often involved in the care of these individuals to address their complex needs.

Smith-Lemli-Opitz syndrome (SLOS) is a genetic disorder that affects the development of multiple body systems. It is caused by a deficiency in the enzyme 7-dehydrocholesterol reductase, which is needed for the production of cholesterol in the body.

The symptoms of SLOS can vary widely in severity, but often include developmental delays, intellectual disability, low muscle tone (hypotonia), feeding difficulties, and behavioral problems. Physical abnormalities may also be present, such as cleft palate, heart defects, extra fingers or toes (polydactyly), and genital abnormalities in males.

SLOS is an autosomal recessive disorder, which means that an individual must inherit two copies of the mutated gene (one from each parent) in order to develop the condition. It is typically diagnosed through genetic testing and biochemical analysis of blood or body fluids. Treatment for SLOS may include cholesterol supplementation, special education services, and management of associated medical conditions.

Flagella are long, thin, whip-like structures that some types of cells use to move themselves around. They are made up of a protein called tubulin and are surrounded by a membrane. In bacteria, flagella rotate like a propeller to push the cell through its environment. In eukaryotic cells (cells with a true nucleus), such as sperm cells or certain types of algae, flagella move in a wave-like motion to achieve locomotion. The ability to produce flagella is called flagellation.

Capillaries are the smallest blood vessels in the body, with diameters that range from 5 to 10 micrometers. They form a network of tiny tubes that connect the arterioles (small branches of arteries) and venules (small branches of veins), allowing for the exchange of oxygen, carbon dioxide, nutrients, and waste products between the blood and the surrounding tissues.

Capillaries are composed of a single layer of endothelial cells that surround a hollow lumen through which blood flows. The walls of capillaries are extremely thin, allowing for easy diffusion of molecules between the blood and the surrounding tissue. This is essential for maintaining the health and function of all body tissues.

Capillaries can be classified into three types based on their structure and function: continuous, fenestrated, and sinusoidal. Continuous capillaries have a continuous layer of endothelial cells with tight junctions that restrict the passage of large molecules. Fenestrated capillaries have small pores or "fenestrae" in the endothelial cell walls that allow for the passage of larger molecules, such as proteins and lipids. Sinusoidal capillaries are found in organs with high metabolic activity, such as the liver and spleen, and have large, irregular spaces between the endothelial cells that allow for the exchange of even larger molecules.

Overall, capillaries play a critical role in maintaining the health and function of all body tissues by allowing for the exchange of nutrients, oxygen, and waste products between the blood and surrounding tissues.
