An endovascular perfusion stent graft is provided that can include a graft device, a balloon, and a perfusion port. The graft device can be configured to be inserted into a vessel. The balloon can be configured to temporarily restrict passage of air or fluid through the vessel when the balloon is temporary inserted into the graft device. The perfusion port can be configured to selectively allow passage of the fluid or the gas through the balloon and to the vessel. The perfusion port can be connected to another perfusion port or to a collection device, such as a heart lung machine. The vessel can be one of an ascending aorta, a descending aorta, or an arch of an aorta.
