Neurocritical care·2012

Endovascular treatments like balloon angioplasty and papaverine infusion effectively manage cerebral vasospasm after subarachnoid hemorrhage. Balloon angioplasty offers a more sustained effect for proximal vessels, while papaverine aids distal treatment.

Area of Science:

  • Neurosurgery
  • Interventional Radiology
  • Vascular Neurology

Background:

  • Subarachnoid hemorrhage frequently causes cerebral vasospasm, a significant cause of secondary brain injury.
  • Cerebral vasospasm can lead to delayed ischemic neurologic deficits and poor patient outcomes.
  • Endovascular therapies have emerged as crucial interventions for managing this condition.

Purpose of the Study:

  • To evaluate the efficacy of endovascular treatments for cerebral vasospasm post-subarachnoid hemorrhage.
  • To compare balloon angioplasty and intra-arterial papaverine infusion in treating cerebral vasospasm.
  • To determine the optimal use of each modality based on vessel location and treatment goals.

Main Methods:

  • Review of endovascular treatment strategies for cerebral vasospasm.

  • Analysis of studies comparing balloon angioplasty and intra-arterial papaverine infusion.
  • Assessment of treatment outcomes including spasm reversal, cerebral blood flow, and neurological deficits.

    • Main Results:

    • Both balloon angioplasty and intra-arterial papaverine infusion effectively reverse cerebral vasospasm and improve cerebral blood flow.
    • Balloon angioplasty demonstrates a more sustained effect in treating proximal cerebral vasospasm.
    • Intra-arterial papaverine is beneficial for distal vasospasm and as an adjunct to balloon angioplasty.

    Conclusions:

    • Endovascular treatment is a valuable therapeutic option for cerebral vasospasm following subarachnoid hemorrhage.
    • Balloon angioplasty is preferred for proximal vasospasm due to its durable effects.
    • Papaverine infusion serves as a vital alternative or adjunctive therapy for distal or inaccessible vasospasm.
