Insights

Carotid angioplasty and stenting proved feasible and safe for patients with carotid artery dissection (CAD) unresponsive to antithrombotic therapy. This endovascular approach offers a viable treatment option for complex cases.

Area of Science:

  • Neurology
  • Vascular Surgery
  • Interventional Cardiology

Background:

  • Carotid artery dissection (CAD) is a significant cause of stroke in younger adults.
  • Failure of antithrombotic therapy in acute CAD necessitates alternative treatment strategies.
  • Symptomatic CAD (sCAD) poses a risk of ischemic events.

Purpose of the Study:

  • To evaluate the procedural feasibility and safety of carotid angioplasty and stenting.
  • To assess the efficacy of endovascular treatment in patients with CAD who failed medical management.
  • To determine the outcomes of stenting in acute carotid artery dissection.

Main Methods:

  • Retrospective review of 33 consecutive patients with sCAD treated between May 2005 and December 2010.
  • Diagnosis confirmed by catheter angiography; patients had failed initial antithrombotic therapy.
  • Analysis of baseline and follow-up data including technical success and complications.

Main Results:

  • Technical success achieved in 32 out of 33 patients (97%) with no intraoperative complications.
  • Two patients (6%) developed ipsilateral Horner sign post-procedure.
  • One patient experienced a transient ischemic attack (TIA) recurrence during follow-up, successfully managed with antithrombotics.

Conclusions:

  • Endovascular stenting is a feasible and safe therapeutic option for CAD patients.
  • Angioplasty and stenting provide a successful alternative when antithrombotic therapy fails.
  • This interventional strategy demonstrates good outcomes in managing complex carotid artery dissections.
