Venous angiomas are currently widely referred to as developmental venous anomalies (DVAs), reflecting the prevailing concept that they represent anomalous, but functional, venous channels within the brain parenchyma. Although DVAs are not infrequently associated with other vascular malformations that harbor hemorrhage risk or can present symptomatically, isolated DVAs themselves appear to be benign lesions with little demonstrable link to hemorrhage, seizures, or headaches. Treatments to remove or occlude DVAs are consequently unnecessary. Furthermore, obliteration of a DVA can be harmful as it can lead to impairment in regional cerebral venous drainage, with the resultant risk of venous congestion, infarction, and hemorrhagic conversion, and the potential for devastating consequences from cerebral edema and mass effect. Consequently, even in the management of associated vascular malformations, it is important to preserve the DVA. In rare cases, DVAs can produce direct compressive symptoms, leading to obstructive hydrocephalus or neurovascular compression. In such cases, cerebrospinal fluid diversion or direct microvascular decompression, respectively, without disruption of the DVA itself is appropriate. In the uncommon setting of spontaneous DVA thrombosis leading to venous infarction, anticoagulation, as recommended for dural and cortical venous thrombosis, is a reasonable consideration. Hemorrhagic presentation from a presumed isolated DVA should prompt careful evaluation for an associated vascular malformation as the true etiology of hemorrhage.

Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves. Venous insufficiency often occurs in the legs, and is associated with EDEMA and sometimes with VENOUS STASIS ULCERS at the ankle.
Rare vascular anomaly involving a communication between the intracranial and extracranial venous circulation via diploe, the central spongy layer of cranial bone. It is often characterized by dilated venous structures on the scalp due to abnormal drainage from the intracranial venous sinuses. Sinus pericranii can be congenital or traumatic in origin.
A vascular anomaly characterized by a radial or wedge-shaped arrangement of dilated VEINS draining into a larger vein in the brain, spinal cord, or the meninges. Veins in a venous angioma are surrounded by normal nervous tissue, unlike a CENTRAL NERVOUS SYSTEM CAVERNOUS HEMANGIOMA that lacks intervening nervous tissue. Drainage of venous angioma is fully integrated with the body's venous system, therefore, in most cases there is no clinical signs and rare bleeding.
Placement of an intravenous catheter in the subclavian, jugular, or other central vein for central venous pressure determination, chemotherapy, hemodialysis, or hyperalimentation.
The blood pressure in the central large VEINS of the body. It is distinguished from peripheral venous pressure which occurs in an extremity.
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
