Clinical presentation of vertebrobasilar stroke

Area of Science:

• Neurology
• Vascular Neurology
• Neuroimaging

Background:

• Vertebrobasilar (VB) stroke accounts for 20% of all strokes and transient ischemic attacks.
• VB ischemia presents with diverse symptoms due to the extensive brain territory supplied.
• Posterior fossa visualization is suboptimal on standard computed tomography, complicating VB stroke diagnosis.

Purpose of the Study:

• To emphasize the importance of recognizing vertebrobasilar stroke.
• To highlight the diagnostic challenges associated with VB stroke.
• To underscore the need for enhanced physician awareness of VB anatomy and clinical presentation.

Main Methods:

• Review of clinical presentations of VB ischemia.
• Analysis of neuroimaging limitations in diagnosing posterior circulation stroke.
• Emphasis on anatomical knowledge of the vertebrobasilar system.

Main Results:

• VB stroke symptoms can mimic other neurological conditions, including carotid territory strokes.
• Computed tomography limitations in visualizing the posterior fossa pose diagnostic hurdles.
• Early recognition is hindered by the complexity and variability of VB stroke presentation.

Conclusions:

• Increased physician awareness of vertebrobasilar anatomy is essential.
• Understanding the clinical spectrum of VB ischemia is critical for timely diagnosis.
• Prompt recognition of VB stroke can improve patient outcomes by facilitating early intervention.
