Summary
Mortality after Total Anterior Circulation Stroke (TACS) decreased with alteplase and endovascular thrombectomy (EVT). These recanalization therapies improve outcomes for acute ischemic stroke patients.
Area of Science:
- Neurology
- Cardiovascular Diseases
- Public Health
Background:
- Acute ischemic stroke, particularly Total Anterior Circulation Stroke (TACS), has high mortality rates despite treatment advances.
- TACS patients, often with middle cerebral artery occlusions, show significant benefit from therapies like endovascular thrombectomy (EVT).
Purpose of the Study:
- To investigate temporal trends in 30-day in-hospital mortality after TACS.
- To identify factors associated with mortality and functional outcomes in TACS patients.
Main Methods:
- Analysis of 1106 community-onset TACS patients from a prospective registry (1994-2019).
- Multivariate analysis of 30-day in-hospital mortality and functional outcomes.
Main Results:
- 30-day in-hospital mortality (41%) initially rose then fell over 25 years.
- Increased mortality linked to age and stroke severity; decreased mortality linked to alteplase, EVT, and early presentation (<12 hours).
- Alteplase, EVT, or both improved functional independence, discharge home, and reduced hospital stay.
Conclusions:
- Recanalization therapies (alteplase, EVT) significantly reduce 30-day mortality in TACS.
- Observational data confirm the clinical benefits of recanalization therapies for acute ischemic stroke.

Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
