Intracranial hemorrhage

Human Brains Causes of Subarachnoid Hemorrhage Chanda Bajracharya February 9, 2018 Midwestern State University Abstract The anatomical study of the brain is known as neuroanatomy, whereas the study of their function is known as neuroscience. The human brain is an extraordinarily powerful organ of the body. It helps to function all the body parts and the amazing fact is it weights around three pounds only. It is covered by the skulls. The largest part of the human brain is cerebrum.…

Decompressive Craniectomy and the Return of Functionality in Traumatic Brain Injury Patients with Increased Intracranial Pressure The brain and its surrounding protective bony layer provide for a unique situation with regards to traumatic brain injuries (TBI). Unlike other tissue in the body, which are free to expand outwards when inflammation or trauma occurs, the brain cannot. In the average adult, the cranial vault has the ability to accommodate for up to 1500mL of volume. When cerebral…

Kofi Gyamfi: Make-up Assignment Cooper Madison, a 6-year-old Caucasian male, arrived at the emergency department at 1045 Tuesday with a closed head injury and concussion, related to a fall from a tree house. A CT scan indicated possible skull fracture and subdural hematoma. A C-spine ruled out spinal fracture. While still in the emergency department, Cooper experienced an unwitnessed seizure. At 1300 Tuesday, Cooper was admitted to the pediatric unit. He has showed signs of decreasing…

When Would You Administer Mannitol? Mannitol is a diuretic. It has many uses. It is most commonly used to increase urine production and flush the kidneys. It can, also, be used to decrease swelling and pressure inside the eye or around the brain. Another use is the elimination of toxic substances, such as aspirin, barbituates, bromides, and carbon monoxide from the body. First, mannitol can perform all of these functions because it is a diuretic. This means that the addition of it to…

Suspected acute subarachnoid hemorrhage or intracranial aneurysm □ Arteriovenous malformations □ Cortical vein thrombosis □ Dural sinus thrombosis □ Vasculitis – Contraindications □ Coagulopathy – Interpretation of results □ Anatomic display of intracranial vasculature, allowing for planning of further therapy and surgical approach if necessary ○ Lumbar puncture 2 – General explanation □ Sampling of cerebral spinal fluid for clinical suspicion of subarachnoid hemorrhage. –…

Brain aneurysms are also referred to as a cerebral aneurysm or intracranial aneurysm. There are four major blood vessel s that supply blood to the brain, two carotid arteries and two vertebral arteries. These blood vessels join together to form the Circle of Willis at the base of the brain, smaller arteries leave the circle and branch out to supply brain cells with oxygen and nutrients. The artery junction points may become weak, as the artery wall becomes thinner from dilation, the blood flow…

In this MRI T-2 Weighted image, the red arrow indicates that there is an excess of Cerebral Spinal Fluid in the intracranial cavity. A condition known as Hydrocephalus, meaning (water in the brain), is caused by an excess of CSF in the intracranial cavity (Blumenfeld, 2010 p. 155). Hydrocephalus can result from an excess of CSF production, obstruction of flow at any point in the ventricles or subarachnoid space, or a decrease in reabsorption via arachnoid granulations (Blumenfeld, 2010 p.…

be a high grade or a low grade. Around 80% of all the primary intrinsic malignant tumors are high grade gliomas. There are three main types of gliomas, Astrocytomas, Oligodendrogliomas and mixed. A high grade glioma is caused due to the raised intracranial pressure. It can lead to seizures. Epilepsy is common with patients with CNS tumors. The grade relies on the size, pattern of venous drainage, and neurologic eloquence of adjacent brain. Grade I malformations are small, superficial, and…

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…
