A stroke caused by bleeding under the thin, delicate membrane surrounding the brain. Thrombolytic Agents Acute interventional drugs which work directly to break up or dissolve stroke-causing clots. Thrombolytics were first used successfully to treat heart attacks. The blockage of a blood vessel caused by the gradual buildup of artherosclerotic plaque deposits along blood vessel walls. A partial blockage is often made complete when a blood clot develops or lodges on top of the deposits, preventing the free flow of blood.
Thrombosis occurs most frequently in blood vessels already compromised by atherosclerosis.
Thrombotic Stroke A stroke resulting from the blockage of a blood vessel by accumulated deposits, with the blockage made complete when a blood clot develops or lodges on top of the deposits, preventing the free flow of blood. Thrombus A blood clot on the wall of a blood vessel. Can grow large enough to block the blood vessel and cause a thrombotic stroke, particularly if a clot forms on top of previous deposits. Transient Ischemic Attack Called TIAs, transient ischemic attacks are temporary interruptions of the blood supply to an area of the brain, typically caused by carotid stenosis. During a TIA, a person experiences a sudden onset of stroke symptoms.
