Summary

Stenting is a safe and feasible treatment for symptomatic vertebrobasilar artery stenosis. While effective, preventing restenosis, particularly in intracranial arteries, remains a key challenge.

Area of Science:

  • Neurology
  • Cardiovascular Surgery
  • Interventional Radiology

Background:

  • Vertebrobasilar artery stenosis (VBAS) can cause significant neurological deficits.
  • Stenting offers a minimally invasive approach to treat arterial stenosis.
  • Limited data exists on long-term outcomes of stenting for VBAS, especially intracranial.

Purpose of the Study:

  • To evaluate the feasibility and safety of stenting for symptomatic vertebrobasilar artery stenosis.
  • To assess the procedural success and complication rates.
  • To analyze the incidence of restenosis and clinical outcomes during follow-up.

Main Methods:

  • Retrospective analysis of 116 patients with symptomatic VBAS treated with stenting.
  • Inclusion criteria: symptomatic lesion, >60% angiographic stenosis.

  • Procedure involved pre-dilatation followed by stent placement under local anesthesia.

    • Main Results:

    • Successful dilatation achieved in 115 patients (99.1%).
    • Mean stenosis reduction to 2% (ostial) and 16% (intracranial).
    • Restenosis occurred in 9.5% (ostial) and 27% (intracranial) of cases; all treated with PTA. Three patients had recurrent VBI symptoms; one developed brainstem infarction due to in-stent occlusion.

    Conclusions:

    • Stenting is a feasible and safe endovascular treatment for symptomatic vertebrobasilar artery stenosis.
    • Restenosis, particularly in intracranial VBAS, is a significant concern requiring further investigation.
    • Ongoing management strategies are needed to prevent restenosis and improve long-term outcomes.
