Do angio before CT in acute stroke patients, Barcelona team urges

By staff writers

March 19, 2021 -- Performing angiography immediately in stroke patients improves treatment time and recovery compared with waiting for a CT scan to be conducted to guide therapy, according to research presented at the American Stroke Association's International Stroke Conference 2021.

Typically, stroke patients are imaged with CT to determine the best course of treatment, but this can result in delays. Instead, it's better to send those patients directly to the angiography suite, according to a research team led by Manuel Requena, PhD, a neurologist and neurointerventionalist fellow at Vall d'Hebron Hospital in Barcelona, Spain,

From 2018 to 2020, 150 patients who were suspected to have blocked blood vessels were randomly assigned to receive either immediate angiography or a CT scan within six hours of admission to Vall d'Hebron Hospital.

In the angiography arm, stroke patients underwent testing within 19 minutes of entering the hospital, whereas CT patients were imaged within 43 minutes. Additionally, patients in the angiography arm received endovascular treatment to restore blood flow 54 minutes faster, on average, compared with patients in the CT arm.

After 90 days, angiography patients were more likely than CT patients to demonstrate a 1-point improvement on the 6-point scale that measures stroke disability, according to Requena and colleagues. For instance, those patients didn't need assistance with daily activities.

The study was the first clinical trial examining what happens when stroke patients are transferred directly to the angiography suite, according to the researchers. Now the data must be confirmed in ongoing, multicenter, international trials.
