IV t-PA influences infarct volume in minor stroke: a pilot study.

ABSTRACT:

Background

There is an ongoing debate whether stroke patients presenting with minor or moderate symptoms benefit from thrombolysis. Up until now, stroke severity on admission is typically measured with the NIHSS, and subsequently used for treatment decision.

Hypothesis

Acute MRI lesion volume assessment can aid in therapy decision for iv-tPA in minor stroke.

Methods

We analysed 164 patients with NIHSS 0-7 from a prospective stroke MRI registry, the 1000+ study (clinicaltrials.org NCT00715533). Patients were examined in a 3 T MRI scanner and either received (n = 62) or did not receive thrombolysis (n = 102). DWI (diffusion weighted imaging) and PI (perfusion imaging) at admission were evaluated for diffusion - perfusion mismatch. Our primary outcome parameter was final
