The superior cerebellar veins pass partly forward and medialward, across the superior cerebellar vermis. They end in the straight sinus, [1] and the internal cerebral veins, partly lateralward to the transverse and superior petrosal sinuses. The inferior cerebellar veins are larger.
Management of cranial venous outflow obstruction involves treating the underlying cause, if identifiable, and managing the symptoms. This can include medication to reduce intracranial pressure, anticoagulation therapy to prevent thrombosis, and in some cases, surgical intervention to restore normal venous drainage. [6] [11]
The deep venous system is primarily composed of traditional veins inside the deep structures of the brain, which join behind the midbrain to form the great cerebral vein (vein of Galen). This vein merges with the inferior sagittal sinus to form the straight sinus which then joins the superficial venous system mentioned above at the confluence ...
According to this theory, dural holes and intracranial hypotension are symptoms caused by low venous pressure in the epidural space. When leg muscles pump blood towards the heart, and pressure in the inferior vena cava vein becomes negative, the network of epidural veins is overdrained, causing CSF to be aspirated into the epidural space.
[14] [30] MS is also more common in women, while venous diseases are more common in men. Venous pathology is commonly associated with hypertension, infarcts, edema and transient ischemia, and occurs more often with age, however these conditions are hardly ever seen in MS and the disease seldom appears after age 50. Finally, an organ-specific ...
A feeling of pressure and squeezing in the chest is a serious indication that medical care is essential because chest pain and discomfort is one of the most common symptoms of heart attack in men.
Cerebellar degeneration is a condition in which cerebellar cells, otherwise known as neurons, become damaged and progressively weaken in the cerebellum. [1] There are two types of cerebellar degeneration; paraneoplastic cerebellar degeneration , and alcoholic or nutritional cerebellar degeneration. [ 2 ]
Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain.The posterior circulation supplies the medulla, pons, midbrain, cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex.
