Summary

Intravenous tissue plasminogen activator (i.v. tPA) is effective for acute ischemic stroke but has a narrow time window. Angiography is increasingly used to guide intra-arterial treatments for stroke.

Area of Science:

  • Neurology
  • Vascular Medicine
  • Medical Imaging

Background:

  • Intravenous tissue plasminogen activator (i.v. tPA) is the standard treatment for acute ischemic stroke.
  • Treatment efficacy is limited by a short therapeutic window (within 3 hours of onset).
  • Computed tomography is required to exclude hemorrhagic stroke before i.v. tPA administration.

Purpose of the Study:

  • To explore the role of angiography in guiding advanced stroke interventions.
  • To evaluate alternative or adjunctive treatment strategies for acute ischemic stroke.

Main Methods:

  • Review of current practices in stroke intervention.
  • Description of angiography-guided intra-arterial thrombolysis.
  • Overview of mechanical endovascular interventions.

Main Results:

  • Angiography enables precise targeting for intra-arterial therapies.
  • Mechanical interventions offer alternative reperfusion strategies.
  • Medical centers are adopting these advanced techniques.

Conclusions:

  • Angiography plays a crucial role in guiding advanced stroke treatments.
  • Intra-arterial therapies and mechanical interventions expand treatment options beyond i.v. tPA.
  • These methods may overcome limitations of the traditional time window for stroke treatment.
