“…In addition, elderly patients often exhibit jugular venous reflux, which leads to stagnation or reversal of the internal jugular vein flow, promoting transmission of increased central venous pressure to the cerebral venous circulation. The internal jugular vein valve, which is critical for the prevention of jugular venous reflux (Lepori et al 1999;Dhanger et al sham control, # P < 0.05 vs. no Ang II. c Cerebral venous congestion induced by JVL is associated with a pro-inflammatory shift in cytokine expression profiles in the mouse hippocampus.…”

“…The IJ vein combines with the subclavian vein that leads to the innominate (brachiocephalic) vein and serves as a vessel that flows the circulated blood from head and neck. Although generally no valves are present in the central veins, a valve is present in the IJ vein, which can act as an obstacle during catheterization and may be damaged during the procedure (1). The IJ vein lies superficial and lateral to the carotid artery in the carotid sheath in the supine position.…”

Central venous catheterization (CVC) is very common procedure in the emergency department and intensive care unit. Although patients undergoing CVC may have various indications and contraindications for this catheterization, the procedure is typically similar, regardless of the route. However, site-specific precautions also exist. This report describes the overall procedure for CVC with access by the internal jugular vein. Neurologic complications such as stroke and cranial air embolism, as well as mechanical complications such as hemopneumothorax and hematoma, can occur related to the internal jugular venous approach to CVC. Clinicians should be aware of these concerns for these patients population.

“…The internal jugular vein valve, which is the only venous valve situated in the venous circulation between the heart and the brain, is critical for the prevention of retrograde flow of venous blood. Despite their clinical significance, the presence and function of the valves in the internal jugular veins are often overlooked (62,115). Anatomical evidence obtained in human cadavers suggests that internal jugular vein valve is frequently incompetent.…”

There has been an increasing appreciation of the role of vascular contributions to cognitive impairment and dementia (VCID) associated with old age. Strong preclinical and translational evidence links age-related dysfunction and structural alterations of the cerebral arteries, arterioles, and capillaries to the pathogenesis of many types of dementia in the elderly, including Alzheimer’s disease. The low-pressure, low-velocity, and large-volume venous circulation of the brain also plays critical roles in the maintenance of homeostasis in the central nervous system. Despite its physiological importance, the role of age-related alterations of the brain venous circulation in the pathogenesis of vascular cognitive impairment and dementia is much less understood. This overview discusses the role of cerebral veins in the pathogenesis of VCID. Pathophysiological consequences of age-related dysregulation of the cerebral venous circulation are explored, including blood-brain barrier disruption, neuroinflammation, exacerbation of neurodegeneration, development of cerebral microhemorrhages of venous origin, altered production of cerebrospinal fluid, impaired function of the glymphatics system, dysregulation of cerebral blood flow, and ischemic neuronal dysfunction and damage. Understanding the age-related functional and phenotypic alterations of the cerebral venous circulation is critical for developing new preventive, diagnostic, and therapeutic approaches to preserve brain health in older individuals.
