The thrombosis of the veins themselves causes venous infarction (damage to brain tissue due to a congested and therefore insufficient blood supply). This results in cerebral edema (both vasogenic and cytotoxic edema), and leads to small petechial haemorrhages that may merge into large haematomas.
CT scan (computed tomography) of the brain (without any iodinated contrast), is the initial imaging choice because of its high speed, good accessibility in hospitals, high sensitivity in detecting brain injuries or brain diseases, thus helping to triage patients in emergency department in a timely manner and urgent neurosurgical intervention ...
The exact process that leads to bleeding depends on the underlying cause. For intraparenchymal hemorrhage associated with hypertension, small holes in arteries are thought to cause bleeding in the deep penetrating arteries of the brain, which are smaller and thinner than other arteries.
Jugular vein thrombosis is a condition that may occur due to infection, intravenous drug use or malignancy. Jugular vein thrombosis can have a varying list of complications, including: systemic sepsis, pulmonary embolism, and papilledema. Though characterized by a sharp pain at the site of the vein, it can prove difficult to diagnose, because ...
Surgery is required if the hematoma is greater than 3 cm (1 in), if there is a structural vascular lesion or lobar hemorrhage in a young patient. [34] A catheter may be passed into the brain vasculature to close off or dilate blood vessels, avoiding invasive surgical procedures. [45]
A germinal matrix hemorrhage is bleeding into the brain of premature infants caused by the rupture of fragile blood vessels within the germinal matrix of premature babies. [18] The germinal matrix is a highly vascularized area within an unborn infant's brain from which brain cells, including neurons and glial cells, originate.
Not long after, the seizures started up again and the family was told that Caper would need a second surgery to remove more pieces of his brain. “The first surgery had a 60% chance of giving him ...
Unlike many effects of stroke, where the clinician is able to judge the particular area of the brain that a stroke has injured by certain signs or symptoms, the causation of apraxia is less clear. A common theory is that the part of the brain that contains information for previously learned skilled motor activities has been either lost or ...
