Delay to Tissue Plasminogen Activator in Hypertensive Stroke Patients: An Analysis of Delay Duration Across Agents.

Background And Purpose: A subset of ischemic stroke patients present with blood pressures above that considered safe for thrombolytic administration, requiring antihypertensive therapy. Guideline statements are ambivalent regarding which antihypertensive agent should be used to obtain a satisfactory blood pressure < 185/110 mm Hg prior to alteplase.

Methods: We reviewed data from consecutive patients at a single institution treated with alteplase from January 2014 to January 2019, collecting door-to-needle times, antihypertensive agent (if used), and antihypertensive-to-needle times.

Tyrosine kinase inhibitor induced rapidly progressive vasculopathy after intracranial stent placement.

Tyrosine kinase inhibitor (TKI) therapy for chronic myeloid leukemia (CML) has been associated with progressive peripheral arterial disease and, more recently, rare cases of intracranial vascular stenosis have been reported. We report the fourth case of TKI treatment associated intracranial vasculopathy and rapid progression of intracranial vascular stenosis following intracranial stent placement. This was a 49-year-old woman who developed right-sided weakness, paresthesias, numbness, and speech difficulties 7 years following TKI treatment for CML.
