Vascular lesions, stroke mechanisms, and correlating functional outcomes in medullary infarction

Takeaway

  • Penetrating artery disease (PAD) is the most common stroke mechanism in medullary infarction (MI) and is generally associated with good 1-year functional outcomes; poor outcomes are more common with large artery occlusive disease (LAOD) or VA dissection.

Why this matters

  • Imaging advances may facilitate better determination of prognosis in patients with MI.
