Arteriovenous malformation is an abnormal connection between arteries and veins, bypassing the capillary system. This vascular anomaly is known because of its occurrence in the central nervous system, but can appear in any location. Although many AVMs are asymptomatic, they can cause intense pain or bleeding or lead to other serious medical problems. AVMs are congenital and belong to the RASopathies; the genetic transmission patterns of AVMs are incomplete, but there are known genetic mutations which can lead to an increased occurrence throughout the body. Symptoms of AVM vary according to the location of the malformation. 88% of people with an AVM are asymptomatic. The most general symptoms of a cerebral AVM include headaches and epileptic seizures, with more specific symptoms occurring that depend on the location of the malformation and the individual; such possible symptoms include: Difficulties with movement coordination, including muscle weakness and paralysis. Cerebral AVMs may present themselves in a number of different ways: Bleeding Acute onset of severe headache.
May be described as the worst headache of the patient's life. Depending on the location of bleeding, may be associated with new fixed neurologic deficit. In unruptured brain AVMs, the risk of spontaneous bleeding may be as low as 1% per year. After a first rupture, the annual bleeding risk may increase to more than 5%. Seizure or brain seizure Depending on the place of the AVM, it can cause loss of vision in one place. Headache Progressive neurologic deficit May be caused by mass venous dilatations. Presence and nature of the deficit depend on the draining veins. Pediatric patients Heart failure Macrocephaly Prominent scalp veins Pulmonary arteriovenous malformations are abnormal communications between the veins and arteries of the pulmonary circulation, leading to a right-to-left blood shunt, they have no symptoms in up to 29% of all cases, however they can give rise to serious complications including hemorrhage, infection. They are most associated with hereditary hemorrhagic telangiectasia. Can occur due to autosomal dominant diseases, such as hereditary hemorrhagic telangiectasia.
Arteries and veins are part of the vascular system. Arteries carry blood away from the heart to the lungs or the rest of the body, where the blood passes through capillaries, veins return the blood to the heart. An AVM interferes with this process by forming a direct connection of the veins. AVMs can lead to serious medical problems. Although AVMs are associated with the brain and spinal cord, they can develop in any part of the body; the arteries in the vascular system carry oxygen-rich blood, except in the case of the pulmonary artery. Structurally, arteries divide and sub-divide eventually forming a sponge-like capillary bed. Blood moves through the capillaries, giving up oxygen and taking up waste products, including CO2, from the surrounding cells. Capillaries in turn successively join together to form veins; the heart acts to uptake the venous blood. As an AVM lacks the dampening effect of capillaries on the blood flow, the AVM can get progressively larger over time as the amount of blood flowing through it increases, forcing the heart to work harder to keep up with the extra blood flow.
It causes the surrounding area to be deprived of the functions of the capillaries—removal of CO2 and delivery of nutrients to the cells. The resulting tangle of blood vessels called a nidus, has no capillaries, it can be fragile and prone to bleeding because of the abnormally direct connections between high-pressure arteries and low-pressure veins. The resultant sign, audible via stethoscope, is a rhythmic, whooshing sound caused by excessively rapid blood flow through the arteries and veins, it has been given French for noise. On some occasions, a patient with a brain AVM may become aware of the noise, which can compromise hearing and interfere with sleep in addition to causing psychological distress. AVMs are diagnosed by the following imaging methods: Computerized tomography scan is a noninvasive X-ray to view the anatomical structures within the brain to detect blood in or around the brain. A newer technology called CT angiography involves the injection of contrast into the blood stream to view the arteries of the brain.
This type of test provides the best pictures of blood vessels through angiography and soft tissues through CT. Magnetic resonance imaging scan is a noninvasive test, which uses a magnetic field and radio-frequency waves to give a detailed view of the soft tissues of the brain. Magnetic resonance angiography – scans created using magnetic resonance imaging to image the blood vessels and structures of the brain. A magnetic resonance angiogram can be an invasive procedure, involving the introduction of contrast dyes into the vasculature of a patient using a catheter inserted into an artery and passed through the blood ves
