Arteriovenous malformation

Historical developments in the treatment of vascular malformation has been since 1762 by Hunter. Further, in 1851 Virchow and others developed a classification of telangiectasias, and of venous, arterial, arteriovenous, and cystic angiomas. The year of 1889, marked the successful excision of an intracranial AVM that was performed. Vascular malformations can be classified as Capillary telangiectasias, Cavernous malformations, Venous malformations, Arteriovenous malformations. The paper focuses on the Arteriovenous malformations (AVM). Mullan and colleagues hypothesized that AVMs begin during human embryonic development during the sequential formation and absorption of surface veins. In the absence of the middle cerebral vein or its failure…

An Arteriovenous Malformation (AVM) can be described simply as a tight rubber band ball of abnormal blood vessels with weak walls. These can be located anywhere in the body. Arteries carry blood containing oxygen from the heart to the brain. An AVM bypasses normal brain tissue and directs blood from the arteries to the veins without a capillary bed in between. Brain AVM’s occur in less than one percent of the population (per 100,000 people) and are more common in males than females. Being…

Introduction A gastrointestinal arteriovenous malformation is a rare defect of tangled veins and arteries involving the intestine. This defect can occur anywhere in the intestine. The defect creates an abnormal collection of blood vessels that can put pressure on other parts of your body that are close by. It causes blood vessels to expand (dilate) over time and sometimes bleed. Many people with this defect never have any symptoms. This defect is present at birth (congenital). What are the…

Spina Bifida (Ridosh, Braun, Roux, Bellin and Swain (2011) state “Spina Bifida is a chronic congenital health defect caused from the incomplete closure of the neural tubes of the spinal cord during the first few days of development. It occurs in almost two out of every 10,000 births.” According to the Spina Bifida Association of America, (2014) there are four different types of Spina Bifida. The first one is, Occult Spinal Dysramphism (OSD). Children born with this particular form of the…

Chiari Malformation Chiari Malformation is, “a condition in which brain tissue extends into the spinal canal”. There are as many as 200,000 diagnoses each year in the United States (Clinic). With this, there is a wide range of people who are affected by this disorder varying from ages, gender, and nationality. Many of those diagnosed, result in surgery for treatment to get rid of the symptoms. Chiari is a horrible condition that affects many and is known to impact lives in various ways. Chiari…

Contemporary Biology Article Assignment To Mend a Birth Defect, Surgeons Operate on the Patient Within the Patient Since the 1990s, Spina Bifida has been repaired by Doctors fetal surgery to lessen the degree of disability. Spina Bifida causes children to not be able to walk, as well as fluid buildup in the brain. It affects 1.500 to 2,000 fetuses a year. The backbone and spinal cord never develop completely or properly causing a gap in the fetus’s lower back exposing bone and nerves. In…

Transition is one on the most painful points of delivery of a baby. However, when you reach transition, the delivery is almost over. This is the point when you want to quit. I remember believing by faith God would give me the ability to deliver Micah naturally. When I finally went into labor, I was excited. Ignorance is bliss! Anyhow, I had a long and difficult labor. When it came time to push, I was exhausted. I recall after pushing for over three long hours, I said, “I quit!” The…

Mathematically Modelling Clinical Resolutions of CSF pressure in Type-I Chiari Malformation and Syringomyelia Patients. Alexander S. Iacobucci, Andrew A. Hassall, Meagan E. Harrington, Korey V. Scanlin Introduction: Type-I Chiari Malformation is a neurological disorder describing the herniation of the cerebellum past the foramen magnum, occasionally resulting in a condition known as Syringomyelia. This disorder causes cysts, known as syrinxes, to form in the spinal cord and result in severe…

Spina Bifida Through the Eyes of Sarah Allison Cover Misericordia University Introduction There are many reasons why I chose to write about spina bifida for this paper. One reason being that November is spina bifida awareness month so I thought it was fitting. Also, I have first-hand experience with children that are living with spina bifida. I am a two-year camp counselor at an amazing camp called Camp Spifida. At this camp, I had the opportunity to meet and work with a little girl named…

Spina bifida is a type neural tube defect where the bones of the spine don’t form properly around part of the baby’s spinal cord. There are three types of spina bifida: spina bifida occulta, meningocele, and myelomeningocele. Spina bifida occulta is the mildest and most common form of spina bifida. It is also called hidden spina bifida. There is usually a small gap in the spine, but no opening or sack on the back. It can be recognized by a tuft or clump of hair, a dimple, or a birthmark where…
