A watershed stroke or watershed infarct is defined as a brain ischemia that is localized to the . as total anterior circulation infarct (TACI), partial anterior circulation infarct (PACI), lacunar infarct (LACI) or posterior circulation infarct ( POCI). A stroke is a medical condition in which poor blood flow to the brain results in cell death. .. This subset of cryptogenetic stroke is defined as a non-lacunar brain infarct without proximal arterial stenosis or cardioembolic sources. About one out of.

Mechanical removal of the blood clot causing the ischemic stroke, called mechanical thrombectomyis today a mainstay of stroke treatment in case of emergent large vessel occlusion ELVO.

Emphasis is often concentrated on functional tasks and people’s goals. Strokes affecting large portions of the brain can cause significant brain swelling with secondary brain injury in surrounding tissue.

Low blood sugar [7].

Explicit use of et al. Because the reduction in blood flow is global, all parts of the brain may be affected, especially vulnerable “watershed” areas—border zone regions supplied by the major cerebral arteries. Archived from the original PDF on Whether tissue is supplied by end arteries e. New research is being conducted in metabolic suppression, direct energy delivery, and selective drug delivery to help salvage this area of the brain after a stroke.

Angioplasty and stenting have begun to be looked at as possible viable options in treatment of acute ischemic stroke. Some current and future therapy methods include the use of virtual reality and video games for rehabilitation. J Stroke Cerebrovasc Dis. In addition to the above CNS pathways, the brainstem gives rise to most of the lacuanr cranial nerves.

However, brain tissue is especially vulnerable to ischemia since it has little respiratory reserve and is completely dependent on aerobic metabolismunlike most other organs. These factors will be discussed further separately. A thrombus itself even if it does not completely block the blood vessel can lead to an embolic stroke see below if lacunag thrombus breaks off and travels in the bloodstream, at which point it is called an embolus.


For the purposes of this article the following definitions are used Lacunwr Cochrane Database of Systematic Reviews.
