24 sie 2023 · The inferior cerebellar veins and their tributaries drain blood into the right and left sigmoid sinuses, inferior petrosal sinus, the occipital and straight sinuses.
24 lip 2023 · Structure and Function. The cerebral veins function to drain the capillary network that supplies the brain with blood; this removes carbon dioxide and other metabolic wastes, and allows fresh blood to flow in to take its place. The cerebral veins drain the entire brain as well as the eyes, meninges, and part of the face via the pterygoid plexus.
30 lip 2024 · Cerebral venous sinus thrombosis (CVST) describes the presence of a thrombus within one of the dural venous sinuses. The thrombus occludes venous return through the sinuses, and causes an accumulation of deoxygenated blood within the brain parenchyma. This in turn can lead to venous infarction.
Fig. 6 Major dural sinuses anteroposterior (A) and lateral (B) views: the superior sagittal sinus (SSS) is midline, unpaired, and drains most of the blood of both hemispheres; the paired transverse (TS) and sigmoid (SS) sinuses drain cerebral venous blood into the paired internal jugular veins.
Originates in the lumbar region and passes through the diaphragm into the thoracic cavity on the right side of the vertebral column; drains blood from the intercostal veins, esophageal veins, bronchial veins, and other veins draining the mediastinal region, and leads to the superior vena cava: Hemiazygos vein
22 sty 2024 · Structurally, the veins of the brain lack a muscular layer (tunica media), which allows them to expand and collapse substantially. There are two types of venous systems that drain the blood from the brain.
12 sty 2021 · The cerebral arterial network of vessels is unique in its anatomy, and its flow dynamics is inextricably intertwined with those of other fluids such as venous blood, cerebrospinal fluid (CSF), and the interstitial fluid (ISF) (2, 3).
