Subarachnoid hemorrhage

of nontraumatic Subarachnoid Hemorrhages (SAH). Saccular aneurysms are known as “berry” aneurysms because of their shape, it looks like a sac or berry forming at the bifurcation of the “Y” segment of the arteries. Fusiform aneurysms are less common and an outpouching of an arterial wall on both sides of the artery like a blood vessel that is expanded in all directions, it does not have a stem and rarely ruptures. When an aneurysm ruptures, it is considered a Subarachnoid hemorrhage (SAH), this…

causes no symptoms or signs and goes overlooked. In exceptional cases, the brain aneurysm ruptures, discharging blood into the skull and distressing a stroke. When a brain aneurysm fallings-out, the outcome is called a subarachnoid hemorrhage. As per the severity of the hemorrhage, brain destruction or death may be the outcome. Risk Factors Brain aneurysms can affect anyone, but people with atherosclerosis (hardening of the arteries) are at high risk of forming brain aneurysms. The Brain…

The lecture summarized an idea about the Gliomas, Meningiomas, Metastatic tumors and miscellaneous tumors. A stroke is defined as a cerebrovascular accident (CVA), cerebrovascular insult (CVI) is when poor blood flow to the brain results in cell death. It disrupts the blood flow. Risk factor includes a heart disease, cardiac arrhythmias, diabetes, smoking, obesity. Strokes can be visualized unto two types ischemic or hemorrhagic. Ischemic is caused due to lack of blood flow. Hemorrhagic is due…

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. –…

“ A stroke occurs when the blood supply to part of your brain is interrupted or severely reduced, depriving brain tissue of oxygen and nutrients”(Mayo Clinic Staff). “Within an hour, the nerve cells in that area of the brain become damaged and die. As a result, the part of the body controlled by the damaged area of the brain cannot work properly” (“Stroke”). Therefore, this leads to the different types of strokes, which are Acute Ischemic stroke and Hemorrhagic stroke. “ In an ischemic stroke,…

characterized by excessive blood within the closed cranial cavity. It is due to brain hemorrhage caused by subarachnoid hemorrhage or intracerebral hemorrhage, only 20% of strokes are hemorrhagic (Caplan, 2014). Intracerebral hemorrhage is when a blood vessel within the brain bursts and leaks into the surrounding brain tissue. Brain cells past the leak are deprived of blood and become damaged. Subarachnoid hemorrhage is when an artery near the surface of the brain bursts open and leaks into the…

Introduction: Head trauma is considered as a common complaint in Emergency Department (ED). Each year, 1.7 million patients are referred to US EDs due to the head trauma [1], which most of them are diagnosed as minor head injury. Although minor head injury is common in Iran, but unfortunately the exact number is unknown. Minor head injury has been defined as Glasgow Coma Scale (GCS) 13-15 [2-4] or GCS equals 14 and 15 [5]. Computed Tomography (CT) is a standard imaging for acute head injury.…

brain distribute the impact when a head gets injury so that it acts like a cushion, dulling the force. Cerebrospinal fluid is one part of the extracellular of the central nervous system and it is a clear, transparent, bodily fluid that occupies the subarachnoid space and the ventricular system around the brain and spinal cord. The Cerebrospinal fluid is produced by choroid plex, which is a structure in the ventricles of the brain. The viscosity of the Cerebrospinal fluid is similar to the blood…

of hemorrhagic strokes, intracerebral hemorrhage and subarachnoid hemorrhage. In an intracerebral hemorrhage, occurs when a blood vessel within the brain ruptures and the blood from the vessel leaks into the brain tissue around it. The neurons in the brain tissue that is exposed to the blood begin to die. This death of neurons will lead to damage to the specific area of the brain affecting all functions controlled by this area. A subarachnoid hemorrhage occurs when there is bleeding between…

management of operative and post operative hemorrhage introduction operative and post operative hemorrhage are a condition of deep bleeding that could face the patient either during surgery (operative) or after (post operative). the causes to this are a lot for example the incision may bleed due to the separation of the stitches , or it could happen internally when some organs get injured during surgery or the blood vessels may need to be secured.the hemorrhage may start shortly after the…
