The majority of neonatal cases (90%) result from applying a vacuum to the head at delivery (ventouse-assisted delivery).The vacuum assist ruptures the emissary veins (i.e., connections between dural sinus and scalp veins) leading to accumulation of blood under the aponeurosis of the scalp muscle and superficial to the periosteum.
Epicranial aponeurosis. Muscles of the head, face, and neck. (Epicranial aponeurosis visible at top labeled 1.) The epicranial aponeurosis (aponeurosis epicranialis, galea aponeurotica) is an aponeurosis (a tough layer of dense fibrous tissue). It covers the upper part of the skull in humans and many other animals.
A: Aponeurosis. The epicranial aponeurosis or galea aponeurotica is a tough layer of dense fibrous tissue which anchors the above layers in place. It runs from the frontalis muscle anteriorly to the occipitalis posteriorly. L: Loose areolar connective tissue. This layer has a gel-like consistency, and allows the more superficial layers of the ...
Intracranial hemorrhage is a serious medical emergency because the buildup of blood within the skull can lead to increases in intracranial pressure, which can crush delicate brain tissue or limit its blood supply. Severe increases in intracranial pressure (ICP) can cause brain herniation, in which parts of the brain are squeezed past structures ...
Specialty. Emergency medicine. A hematoma, also spelled haematoma, or blood suffusion is a localized bleeding outside of blood vessels, due to either disease or trauma including injury or surgery [1] and may involve blood continuing to seep from broken capillaries. A hematoma is benign and is initially in liquid form spread among the tissues ...
Internal bleeding (also called internal haemorrhage) is a loss of blood from a blood vessel that collects inside the body, and is not usually visible from the outside. [1] It can be a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding (e.g. head, torso, extremities).
Endovascular coiling is an endovascular treatment for intracranial aneurysms and bleeding throughout the body. The procedure reduces blood circulation to the aneurysm through the use of microsurgical detachable platinum wires, with the clinician inserting one or more into the aneurysm until it is determined that blood flow is no longer occurring within the space.
Treatment. Management can be physical, occupational, or speech therapy. [2] Cerebral amyloid angiopathy (CAA) is a form of angiopathy in which amyloid beta peptide deposits in the walls of small to medium blood vessels of the central nervous system and meninges. [2][3] The term congophilic is sometimes used because the presence of the abnormal ...
