Insights

Emergency carotid artery stenting after intravenous tissue plasminogen activator (t-PA) treatment showed no intracranial hemorrhaging in three patients. However, one experienced stent reocclusion, necessitating new antiplatelet strategies.

Area of Science:

  • Neurology
  • Interventional Cardiology
  • Vascular Surgery

Background:

  • Ischemic stroke treatment often involves reperfusion therapies like intravenous tissue plasminogen activator (t-PA).
  • Carotid artery stenting is an emergency procedure for select ischemic stroke patients.
  • Optimal antiplatelet strategies during and after stenting in t-PA treated patients remain under investigation.

Observation:

  • Three patients with acute ischemic stroke underwent emergency carotid artery stenting post-t-PA administration.
  • Patients received immediate antiplatelet loading and dual antiplatelet therapy (DAPT) post-procedure.
  • No symptomatic intracranial hemorrhaging was observed in any patient during the follow-up period.

Findings:

  • Despite high-dose and dual antiplatelet therapy, one patient developed acute stent thrombosis and reocclusion.
  • The remaining two patients had successful stent patency without hemorrhagic complications.
  • This case highlights a potential risk of thrombotic complications even with aggressive antiplatelet regimens.

Implications:

  • Current antiplatelet protocols may require modification for patients undergoing emergency carotid stenting after t-PA.
  • Further research is needed to establish optimal dual antiplatelet therapy strategies to prevent stent thrombosis in this specific patient population.
  • Developing tailored treatment algorithms is crucial for improving outcomes in acute ischemic stroke patients treated with combined reperfusion and endovascular therapy.
