Insights

This case report details a rare instance of simultaneous bilateral anterior cerebral artery dissection leading to severe cerebral infarction. Despite treatment, the patient experienced significant neurological deficits, highlighting the critical nature of this condition.

Area of Science:

  • Neurology
  • Vascular Neurology
  • Neuroimaging

Background:

  • Cerebral infarction, particularly affecting the anterior cerebral artery (ACA) territories, can result from various vascular pathologies.
  • Arterial dissection is a recognized cause of stroke, but bilateral involvement of the ACA is exceptionally rare.

Observation:

  • A 38-year-old male presented with progressive neurological deficits including headache, dysarthria, and paraparesis.
  • Brain imaging revealed infarction in bilateral ACA territories, with subsequent deterioration despite antithrombotic therapy.
  • Cerebral angiography demonstrated occlusion and contrast pooling in the right ACA A2 segment, with stenosis and dilatation in the left ACA A2 segment, alongside an intimal flap.

Findings:

  • The patient was diagnosed with cerebral infarction secondary to bilateral anterior cerebral artery dissection.
  • The dissection involved the A2 segments of both ACAs, presenting with distinct angiographic findings in each artery.
  • Despite intensive antithrombotic therapy, the patient exhibited severe neurological impairment, including akinetic mutism and hemiparesis.

Implications:

  • This case underscores the possibility of simultaneous bilateral dissection of the anterior cerebral arteries as a cause of ischemic stroke.
  • Prompt diagnosis and understanding of the pathophysiology of ACA dissection are crucial for effective management and improved patient outcomes.
  • Further research into the underlying causes and optimal treatment strategies for bilateral arterial dissection is warranted.

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

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.

Stroke: 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...
Transient Ischemic Attack l: Introduction01:26

Transient 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...
Hemorrhagic Stroke l: Introduction01:17

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...

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...
