Acute hemodynamic disturbances like bradycardia and hypotension are common during carotid stenting but rarely lead to adverse outcomes. Most procedures show excellent results, even in high-risk patients.

Area of Science:

  • Cardiovascular Medicine
  • Interventional Neurology

Background:

  • Carotid artery stenosis poses a significant risk for stroke.
  • Carotid stenting is an established treatment option for high-grade stenosis.
  • Hemodynamic changes during stenting can impact patient outcomes.

Purpose of the Study:

  • To evaluate the clinical significance of hemodynamic disturbances during carotid stenting.
  • To correlate intraprocedural heart rate (HR) and blood pressure (BP) changes with adverse neurologic and cardiac events.

Main Methods:

  • Nineteen patients with >60% carotid artery stenosis underwent stenting with Wallstent.
  • Intraprocedural HR and BP were monitored during predilatation, stent delivery, and postdilatation.
  • Bradycardia and hypotension were defined and analyzed in relation to procedural phases.

Main Results:

  • Hemodynamic disturbances (bradycardia/hypotension) occurred in 68% of procedures.
  • Persistent disturbances requiring medication were noted in 37% of patients.
  • Hypotension was significantly more frequent during postdilatation (32%) versus predilatation (5%).
  • Prophylactic atropine did not reduce bradycardia.

Conclusions:

  • Despite frequent hemodynamic fluctuations during carotid stenting, most procedures yield excellent results.
  • Adverse neurologic and cardiac outcomes are rare, even in high-risk patients.
  • Careful monitoring and management of hemodynamic changes are important during carotid stenting.
