Intravenous thrombolysis (IVT) may be beneficial for acute stroke patients with cervical artery dissection. Intra-arterial thrombolysis (LIT) shows comparable outcomes to other studies, but requires individualized treatment decisions.

Area of Science:

  • Neurology
  • Vascular Neurology
  • Interventional Neurology

Background:

  • Spontaneous cervical artery dissection (sCAD) is a leading cause of stroke in young adults.
  • Controlled randomized trials assessing thrombolysis in sCAD are lacking.
  • Limited data exist on the safety and efficacy of intravenous thrombolysis (IVT) and intra-arterial thrombolysis (LIT) for acute stroke secondary to sCAD.

Purpose of the Study:

  • To review available data on the safety and efficacy of IVT and LIT in patients with acute stroke due to spontaneous cervical artery dissection.
  • To evaluate outcomes and complications associated with these interventions.

Main Methods:

  • Systematic review of studies involving IVT for internal carotid artery dissection.
  • Analysis of case reports on LIT for carotid or vertebral artery dissection.

  • Assessment of patient demographics, procedural details, complications, mortality, and functional outcomes (modified Rankin Scale).

    • Main Results:

    • IVT data from 50 patients showed 8% mortality and 40% good outcomes (mRS 0-2). No new local signs or hemorrhages were observed, though one patient deteriorated.
    • LIT data from 15 patients reported 13% mortality and 60% good outcomes (mRS 0-2), with no reported intracranial hemorrhage or recurrent embolism.
    • LIT outcomes appear comparable to the PROACT II study's active arm.

    Conclusions:

    • Current data suggest IVT should not be withheld in acute stroke patients with cervical artery dissection.
    • LIT treatment decisions for cervical artery dissection should be individualized based on available evidence.
    • Further research, including randomized controlled trials, is needed to definitively establish the role of thrombolysis in sCAD.
