Carotid and vertebral arterial dissections in the emergency department

Area of Science:

• Neurology
• Vascular Surgery
• Emergency Medicine

Background:

• Cervical arterial dissection involves damage to the intimal wall of carotid or vertebral arteries.
• This damage can lead to thrombus formation, potentially causing stroke, pseudoaneurysm, or vessel occlusion.
• Intracranial dissections may also result in subarachnoid hemorrhage.

Purpose of the Study:

• To emphasize the importance of early consideration and rapid exclusion of cervical arterial dissection in emergency settings.
• To highlight diagnostic and treatment strategies for cervical arterial dissections.
• To inform about the risks of recurrence and rebleeding.

Main Methods:

• Diagnostic imaging modalities include computed tomographic angiography, magnetic resonance angiography, and digital subtraction angiography.
• Treatment primarily involves anticoagulation or antiplatelet therapy to mitigate stroke risk.
• Endovascular therapy or surgical intervention may be considered in select cases.

Main Results:

• Timely diagnosis and treatment initiation are key to effective management of cervical arterial dissections.
• Anticoagulation/antiplatelet therapy is the standard treatment for reducing stroke risk.
• Recurrence and rebleeding represent significant risks that necessitate careful management.

Conclusions:

• Cervical arterial dissections, presenting with common symptoms like headache and stroke, must be rapidly diagnosed and treated.
• Prompt diagnostic workup and appropriate therapeutic interventions, including anticoagulation or antiplatelet agents, are essential.
• Vigilant management is required to address the significant risks of recurrence and rebleeding.
