The venous drainage of the cerebrum can be separated into two subdivisions: superficial and deep. The superficial system. The superficial system is composed of dural venous sinuses, sinuses (channels) within the dura mater. The dural sinuses are therefore located on the surface of the cerebrum.
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.
Pregnancy from 24–28 Weeks Gestation: Intervention should be provided only after educating decision-makers of potential risks. Pregnancy after 28 Weeks Gestation: Intervention should be provided until fetus can be delivered or the mother's condition worsens. A second view considers the autonomy of the mother and her right to die. For example ...
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 ...
The superior thalamostriate vein or terminal vein commences in the groove between the corpus striatum and thalamus, receives numerous veins from both of these parts, and unites behind the crus of the fornix with the superior choroid vein to form each of the internal cerebral veins.
The heart failure is due to the size of the arteriovenous shunt that can steal 80% or more of the cardiac output, with large volumes of blood under high pressure returning to the right heart and pulmonary circulation and sinus venosus atrial septal defects. [4] [5] It is also the most common cause of death in such patients. [6]
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.
The paired (right and left) thalamogeniculate veins (Latin: venae thalamo-geniculatae dextra et sinistra) originate each from the posterior part of the thalamus. Their course roughly corresponds to the course of the corresponding thalamogeniculate artery on this side. They drain blood from the pulvinar, medial and lateral geniculate bodies.
