What is anterior ischemia?
The anterior wall ischaemia/infarction involving the left anterior descending artery (LAD) is usually represented on the ECG with ST-T changes in the precordial leads and in leads I and aVL while those of the inferior wall classically involve leads II, III and aVF.
What is the most common presenting symptom of posterior circulation ischemia?
Common Symptoms of Posterior Circulation Stroke Common presenting symptoms of PC stroke include vertigo, imbalance, unilateral limb weakness, slurred speech, double vision, headache, nausea, and vomiting. Exam findings include unilateral limb weakness, gait ataxia, limb ataxia, dysarthria, and nystagmus.
What is a PCA stroke?
Posterior cerebral artery (PCA) stroke is less common than stroke involving the anterior circulation. An understanding of PCA stroke phenomenology and mechanisms requires knowledge of neurovascular anatomy and of the structure-function relationships of this region of the brain.
How common is posterior circulation stroke?
Posterior circulation stroke (PCS), caused by infarction within the vertebrobasilar arterial system, is a potentially life-threatening condition and accounts for about 20–25% of all ischemic strokes.
What are the 5 D’s of posterior stroke?
Classically, the “Five D’s” were used to describe the signs and symptoms of a posterior stroke: dizziness, diplopia, dysarthria, dysphagia, dystaxia. Additionally, you can have motor and/or sensory deficits, which mimic an anterior circulation stroke.
Can you recover from a posterior stroke?
Mortality associated with isolated posterior cerebral artery (PCA) stroke is low; therefore, the prognosis is generally good. Visual field deficits improve to varying degrees; however, they may be permanent and associated with morbidity.
What is affected by a PCA stroke?
PCA strokes can restrict the blood supply of multiple brain regions, including the occipital lobe, the inferomedial temporal lobe, a large portion of the thalamus, and the upper brainstem and midbrain.
