FAQ
A normal physiological condition such as “patent” (meaning open) “antegrade flow” (meaning flowing forward) of the vertebral arteries” is not dangerous., rather it is totally appropriate.
Presence of antegrade flow was significantly associated with large artery atherosclerosis as the cause of stroke. Rate of antegrade flow was much higher in patients with the large artery atherosclerosis subtype than in those with cardioembolism.
We defined antegrade flow as early opacification at the distal interface of the clot with subsequent distal extension on 4‐dimensional computed tomography angiography.
Antegrade: Forward-moving. As in blood flow. Sometimes synonymous with anterograde.
In the presteal waveform, because of less significant subclavian stenosis, vertebral artery flow is always antegrade but with a transient sharp deceleration of blood flow after the first systolic peak 7 (Fig.
The normal range for net vertebral artery flow volume defined by the 5th to 95th percentiles is between 102.4 and 301.0 mL/min.
Ultrasound of the vertebral arteries can be variable in diameter. They should always demonstrate antegrade flow (toward the brain) and be low resistance similar to the ICA. Arrows indicate normal flow direction in the extra cerebrovascular circulation.
Meaning of antegrade in English used to describe a forward direction or movement, for example the normal flow of blood in the body: The treatment resulted in improved antegrade pulmonary blood flow. Antegrade and retrograde catheters are placed prior to cross-clamping. See also. anterograde.
