We present a case of accidental stent-graft deployment from the true lumen into the false lumen during TEVAR, resulting in hemodynamic collapse and visceral malperfusion. We successfully performed a bailout using the Brockenbrough needle to create new access from the true lumen to the false lumen and implanted another overlapping stent graft. https://rhythm.tums.ac.ir/index.php/jthc/article/view/1476 https://rhythm.tums.ac.ir/index.php/jthc/article/download/1476/1019
