The veins of the brain, both the superficial veins and the deep venous system, empty into the dural venous sinuses, which carry blood back to the jugular vein and thence to the heart. In cerebral venous thrombosis, blood clots usually form both in the veins of the brain and the venous sinuses.
While venous thrombosis of the legs is the most common form, venous thrombosis may occur in other veins. These may have particular specific risk factors: [5] Cerebral venous sinus thrombosis, cavernous sinus thrombosis and jugular vein thrombosis: thrombosis of the veins of the brain and head
An angiogram will show whether the blood vessel is blocked by a clot, the blood vessel is narrowed, or if there is an abnormality of a blood vessel known as an aneurysm. Carotid duplex : A carotid duplex is an ultrasound study that assesses whether or not you have atherosclerosis (narrowing) of the carotid arteries.
Once clots have formed, other drugs can be used to promote thrombolysis or clot breakdown. Streptokinase, an enzyme produced by streptococcal bacteria, is one of the oldest thrombolytic drugs. [14] This drug can be administered intravenously to dissolve blood clots in coronary vessels. However, streptokinase causes systemic fibrinolytic state ...

Mitral stenosis poses a high risk of forming emboli which may travel to the brain and cause stroke. [2] Endocarditis increases the risk for thromboembolism, [2] by a mixture of the factors above. Atherosclerosis in the aorta and other large blood vessels is a common risk factor, [2] both for thromboembolism and cholesterol embolism.
Clots can break off blood vessels and travel to the heart, triggering a heart attack, or to the brain, triggering a stroke. Previous research has linked erythritol to a higher risk of stroke ...
AFib, the most common heart rhythm disorder, is linked to a 39% increased risk of cognitive impairment, while coronary heart disease increases the risk of dementia by 27%, with up to 50% of heart ...
