Podcast 688: tPA Before Thrombectomy

Contributor: Aaron Lessen, MD

Educational Pearls:

DEVT Trial, a recent non-inferiority study, looked at giving tPA prior to endovascular thrombectomy and was stopped early because there was no benefit shown to giving tPA before this intervention
Coupled with the SKIP and DIRECT MT trials corroborating these findings, it appears that giving tPA prior to thrombectomy is not indicated
Whether patients should receive tPA prior to transfer for thrombectomy (i.e. they are in a rural healthcare setting) is still unclear
