1. A transcarotid access system configured for treatment of a neurovascular condition, comprising: an arterial access sheath having a sheath body defining an internal lumen, the sheath body sized and shaped to be introduced into an opening in a common carotid artery and receive blood flow from the carotid artery; an adapter positioned at a proximal end of the sheath body, the adapter having a hub adapted to be removably connected to a flow shunt line, the adapter further having a valve positioned adjacent to an internal lumen of the transcarotid access system, wherein the valve regulates fluid flow out of the internal lumen of the arterial access sheath toward the hub; and a proximal extension connected to a proximal end of the adapter, the proximal extension having an internal lumen in fluid communication with the internal lumen of the arterial access sheath via the adapter, the proximal extension formed of an elongated body that defines a proximal opening that communicates with the internal lumen of the proximal extension, wherein the proximal opening is completely unimpeded.
