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
