This is called a stenotic vessel. This is usually due to atherosclerotic changes caused by buildup of lipids in the walls of vessels over time.

How did Angioplasty used to be done?
Angioplasty was originally performed by dilating the vessel with the introduction of larger and larger stiff catheters through the narrowed space
What is the surgical widening of a constricted heart valve called?
An angioplasty is the widening of a narrowed blood vessel. A stent is a tube inserted to prevent constriction.
When can a sailing vessel becomes a power driven vessel?
When the sails are furled and it is proceeding under its auxilliary engine
How were angioplasties originally performed?
by dilating the blood vessel with the introduction of larger and larger stiff catheters through the narrowed space. The complications that resulted from this approach led researchers to develop ways to open the vessel with smaller devices
When can a power driven vessel becomes a sailing vessel?
When being propelled by wind alone and without auxiliary motive force.
What happens when you lasso a horse?
A lasso is twirled above the head of a person, forming a circle which is then tossed over the horse's head and then tightened around his neck. After the lasso is tightened, controlling the horse becomes much easier.
When does a power-driven vesel becomes a sailing vessel?
When sails are up and are producing more momentum then power (if the vessel is still using power to make way)
A technique of mechanically widening a narrowed or obstructed blood vessel?
Well it really depends on the nature of the narrowing to dictate the particular course of treatment for arterial narrowing (stenosis) or obstruction (atresia). For example, if the stenosis or atresia is congenital (baby is born with it), then the baby will likely undergo a series of corrective surgeries to reconstruct the malformed vessel-- this is especially true with stenosis or atresia of the cardiovascular organs (i.e., aorta and pulmonary artery). In contrast, when a once healthy and normal vessel has become narrowed or obstructed, it is often due to the presence and buildup of atherosclerotic plaque, likely related to chronic high cholesterol (specifically, LDL), and an angioplasty is performed (balloon inflation and removal to reopen the vessel-- see link below!) and/or a stent is placed to retain the newly widened artery. Bottom line, it is important to remember that the smooth muscle/connective tissue composition of arteries is what allows them to be strong enough to withstand high-volume flow, but also gives the vessel a high noncompliance, and treatment of arterial stenosis or atresia can sometimes be difficult as a result.
What does neural compromise mean?
Neural compromise, also referred to as neural foraminal compromise, is a health condition. It's when the spinal column's foreman becomes narrowed.
Which cardiovascular problem results when a blood vessel in the brain becomes blocked or ruptures?
Stroke
What form blood clots when a blood vessel is cut?
Yes platelets form a sticky clot when a blood vessel is cut.
What can an abnormal angiogram reveal?
may display a narrowed blood vessel with decreased arterial blood flow (ischemia) or an irregular arrangement or location of blood vessels. The results of an angiogram vary widely by the type of procedure performed
