Timing of Intervention in Symptomatic Carotid Artery Stenosis

Area of Science:

• Vascular Surgery
• Neurology
• Interventional Cardiology

Background:

• Symptomatic carotid artery stenosis involves neurologic deficits ipsilateral to >50% carotid stenosis.
• Surgical intervention benefits symptomatic carotid stenosis, but optimal timing remains unclear.
• Intervention timing must balance perioperative risks (higher within 48 hours) and recurrent stroke risks (higher after 14 days).

Purpose of the Study:

• To explore the optimal timing for intervening in symptomatic carotid artery stenosis.
• To analyze factors influencing perioperative stroke and death risks.
• To compare outcomes of different surgical interventions.

Main Methods:

• Review of previous studies on symptomatic carotid stenosis intervention.
• Analysis of factors affecting perioperative risks (neurologic deficit acuity, stenosis degree, comorbidities).
• Comparison of carotid endarterectomy and transcarotid revascularization outcomes.

Main Results:

• The optimal timing for intervention requires balancing acute perioperative risks against risks of recurrent stroke.
• Factors like neurologic deficit acuity, stenosis degree, and comorbidities influence perioperative risk.
• Transcarotid revascularization shows similar outcomes to carotid endarterectomy in recent studies.

Conclusions:

• Optimal timing for carotid stenosis intervention is critical to minimize overall stroke risk.
• Individual patient factors must be considered when determining intervention timing.
• Both carotid endarterectomy and transcarotid revascularization are viable options for symptomatic carotid stenosis.
