4 doctors agree

In brief: Think this way

Like stepping on a garden hose cuts down the amount of water coming out of the hose, a vasodilator would remove your foot from the hose allowing more water to flow.
Similarly, vasodilators enhance blood flow through a constricted vessel and help blood flow to an area being robbed of that important blood.

Great analogy. Agree fully with Dr. Armstrong's response.

Good answer.

In brief: Can be good

So long as the vasodilator isn't so potent as to cause a precipitous drop in blood pressure with consequent underperfusion of vital vascular beds, it's good.
Example: intravenous (so it can be carefully controlled) Nitroglycerin is helpful for an acute mi (heart attack) and often used. The worst thing to do for a stroke, though, is to cause hypotension which can extend the damage.
