Question

Quizplus · Accepted Answer

Obstructive strokes occur when blood flow to the brain is blocked, typically by a thrombus (a blood clot that forms in a blood vessel) or an embolus (a blood clot or other material that travels through the bloodstream from another part of the body and lodges in a blood vessel in the brain). This is the most common cause of obstructive strokes.
