Cerebral venous sinus thrombosis (CVST), cerebral venous and sinus thrombosis or cerebral venous thrombosis (CVT), is the presence of a blood clot in the dural venous sinuses (which drain blood from the brain), the cerebral veins, or both. Symptoms may include severe headache, visual symptoms, any of the symptoms of stroke such as weakness of ...
Chronic cerebrospinal venous insufficiency (CCSVI or CCVI) is a term invented by Italian researcher Paolo Zamboni in 2008 to describe compromised flow of blood in the veins draining the central nervous system. [1][2] Zamboni hypothesized that it might play a role in the cause or development of multiple sclerosis (MS). [3][4] Zamboni also ...
Microangiopathy (also known as microvascular disease, small vessel disease (SVD) or microvascular dysfunction) is a disease of the microvessels, small blood vessels in the microcirculation. [1] It can be contrasted to macroangiopathies such as atherosclerosis, where large and medium-sized arteries (e.g., aorta, carotid and coronary arteries ...
2 per 100,000 per year [4] Idiopathic intracranial hypertension (IIH), previously known as pseudotumor cerebri and benign intracranial hypertension, is a condition characterized by increased intracranial pressure (pressure around the brain) without a detectable cause. [2] The main symptoms are headache, vision problems, ringing in the ears, and ...
The pathophysiology of cranial venous outflow obstruction involves the disruption of normal venous drainage from the brain. Cerebral veins play a crucial role in draining brain interstitial fluid (ISF), and their significance has been linked in various neurological conditions. [1] It can be caused by extrinsic or intrinsic anomalies.
Symptoms of a DVT will include unilateral leg swelling and pain, warmth, and redness of the affected area. [9] This is due to the blockage of blood attempting to return to the heart through the venous system. Additional findings in a patient with a paradoxical embolism will be dependent upon where the emboli lodges and disrupts blood flow.
Neurology. Binswanger's disease, also known as subcortical leukoencephalopathy and subcortical arteriosclerotic encephalopathy, [1] is a form of small-vessel vascular dementia caused by damage to the white brain matter. [2] White matter atrophy can be caused by many circumstances including chronic hypertension as well as old age. [3]
Signs and symptoms. 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 ...
