In a study on the circle of Willis and its relation to cerebral vascular disorders, a comparison on various anomalies between normal brains (those without the condition of cerebral softening) and brains with cerebral softening were looked at to observe trends in the differences of the anatomical structure of the circle of Willis.
Most cases of primary intraparenchymal hemorrhage are the result of chronic hypertension (high blood pressure), cerebral amyloid angiopathy, or both. While these are the causative processes for most cases, a number of other pathological processes are known to accelerate or worsen them, including coagulopathy , vasculitis , brain tumors ...
Treatment depends substantially on the type of ICH. Rapid CT scan and other diagnostic measures are used to determine proper treatment, which may include both medication and surgery. Tracheal intubation is indicated in people with decreased level of consciousness or other risk of airway obstruction.
Laser surgery is a treatment option which uses a laser beam to seal off damaged blood vessels in the retina. [9] Anti-vascular endothelial growth factor (VEGF) drugs like Avastin and Lucentis have also been shown to repair retinal hemorrhaging in diabetic patients and patients with hemorrhages associated with new vessel growth.
Most subdural hygromas are believed to be derived from chronic subdural hematomas. They are commonly seen in elderly people after minor trauma but can also be seen in children following infection or trauma. One of the common causes of subdural hygroma is a sudden decrease in pressure as a result of placing a ventricular shunt.
Radwah Oda was diagnosed with colon cancer at 30. She shares five symptoms she dismissed, including narrow stools, blood in the stool, pain and fatigue.
MRI is more useful than CT for detecting characteristics of diffuse axonal injury in the subacute and chronic time frames. [35] Newer studies such as Diffusion Tensor Imaging are able to demonstrate the degree of white matter fiber tract injury even when the standard MRI is negative.
The treatment of wounds depends on whether they are external or internal. External wounds bleed outside through a skin break. They need an external wound management (read below). Internal wounds bleed inside, but some of them can pour blood outside through a natural hole. They need an internal wound management (read below).
