Picture-to-puncture time in acute stroke endovascular intervention: are we getting faster?

Background In acute stroke management, time efficiency in the continuum of patient management is critical. We aimed to determine if implementation of system improvements at our institution translated to reduced picture-to-puncture (P2P) times over a 6-year period.

Methods We conducted a single-center retrospective analysis using a prospective acute stroke database of patients treated with intra-arterial therapy from October 2007 to October 2013. Patient demographics, stroke severity, neuroimaging and treatment time points were collected. Annual P2P times, defined as the interval between pretreatment neuroimaging (picture) and commencement of intra-arterial therapy (puncture), were assessed and compared.
