Summary
This study on posterior circulation stroke (PCS) in Qatar found unique causes and lesion patterns. Outcomes showed a majority of patients discharged home with good recovery, but a notable mortality rate.
Area of Science:
- Neurology
- Stroke Medicine
- Epidemiology
Background:
- Posterior circulation stroke (PCS) presents unique clinical challenges.
- Regional variations in PCS characteristics and outcomes are under-documented.
- This study addresses the knowledge gap in PCS in Qatar.
Purpose of the Study:
- To characterize the demographics, risk factors, and clinical presentation of PCS patients in Qatar.
- To investigate the etiological patterns and lesion topography in PCS.
- To evaluate the short-term and medium-term outcomes of PCS.
Main Methods:
- Prospective data collection of 116 PCS patients admitted between 2005-2008.
- Recording of demographics, risk factors, symptoms, etiology, imaging, complications, and outcomes.
- Assessment of outcomes at discharge and 30-day/90-day follow-up using modified Rankin Scale (mRS).
Main Results:
- Mean age 53 years, 85% males; diverse ethnic origins (47% Arab, 51% South Asian).
- Major risk factors: obesity (66%), hypertension (61%). 64% had minimal/fluctuating symptoms.
- Large artery disease (53%) and proximal territory lesions (39%) were common. 70% discharged home; 89% alive at 90 days with good outcome (mRS ≤ 2).
Conclusions:
- The etiological profile and lesion topography of PCS in Qatar's population are distinct.
- PCS in this region is associated with significant risk factors like obesity and hypertension.
- Outcomes are generally favorable, but regional differences necessitate tailored management strategies.

01:15Ischemic 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...
01:15Ischemic 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.
01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
01:29Stroke: Introduction and Types
A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...
01:17Hemorrhagic 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...
01:29Hemorrhagic 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...
