Summary
A patient experienced stroke symptoms like hemiparesis after carotid artery stenting. This case highlights cerebral hyperperfusion syndrome as a rare cause of stroke following the procedure.
Area of Science:
- Neurology
- Vascular Surgery
- Radiology
Background:
- Severe asymptomatic carotid artery stenosis poses a risk for stroke.
- Carotid artery stenting is a common intervention to prevent ischemic events.
Observation:
- A patient developed hemiparesis and drowsiness 30 minutes post-carotid artery stenting.
- Cerebral imaging revealed increased signal intensity in the left middle cerebral artery distribution without infarction or hemorrhage.
Findings:
- The patient's symptoms were attributed to cerebral hyperperfusion syndrome.
- This syndrome is an uncommon but significant complication of carotid revascularization.
Implications:
- Cerebral hyperperfusion syndrome should be considered in patients with neurological deficits post-carotid stenting.
- Early recognition and management are crucial for patient outcomes.

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...
01:26Transient 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...
01:15Ischemic 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.
