The superior thalamic vein (Latin: vena superioris thalami), initially called by Benno Shlesinger in 1976 the principal thalamic vein (vena principalis thalami) or centro-medial thalamic vein (vena centro-medialis thalami), also called by Russian surgeon Pirogoff internal thalamic vein (vena interioris thalami) is the most prominent vein of the thalamus.
The epidemiology of cranial venous outflow obstruction is not well-studied, and the condition is likely underdiagnosed due to the nonspecific nature of its symptoms. However, it is known to affect individuals of all ages, with a higher prevalence in females and individuals with anatomical venous disorders (varicose veins), certain risk factors ...
A developmental venous anomaly (DVA, formerly known as venous angioma) is a congenital variant of the cerebral venous drainage. On imaging it is seen as a number of small deep parenchymal veins converging toward a larger collecting vein.
Tobacco smoking during pregnancy causes many detrimental effects on health and reproduction, in addition to the general health effects of tobacco.A number of studies have shown that tobacco use is a significant factor in miscarriages among pregnant smokers, and that it contributes to a number of other threats to the health of the foetus.
Causes [2] of venous stasis include: Obesity; Pregnancy; Previous damage to leg; Blood clot; Smoking; Swelling and inflammation of a vein close to the skin; Congestive heart failure. [3] Long periods of immobility that can be encountered from driving, [4] flying, bed rest/hospitalization, or having an orthopedic cast.
The most frequently observed problems related to a cerebral arteriovenous malformation (AVM) are headaches and seizures, cranial nerve afflictions including pinched nerve and palsy, [2] [3] backaches, neckaches, and nausea from coagulated blood that has made its way down to be dissolved in the cerebrospinal fluid.
Venous stasis may occur at the end of the first trimester, due to enhanced compliance of the vessel walls by a hormonal effect. [2] Also, pregnancy can cause hypercoagulability by other factors, e.g. the prolonged bed rest that often occurs post partum that occurs in case of delivery by forceps, vacuum extractor or Caesarean section.

These sinuses play a crucial role in cerebral venous drainage. A dural venous sinus, in human anatomy, is any of the channels of a branching complex sinus network that lies between layers of the dura mater, the outermost covering of the brain, and functions to collect oxygen-depleted blood. Unlike veins, these sinuses possess no muscular coat.
