Venous arterialization occurs when a vein segment is transposed as a bypass graft into the arterial circulation, resulting in a structural and functional reorganization of the vascular wall in response to the new local biomechanical environment. Although the anatomical changes of venous arterialization have been well characterized, the molecular mechanisms of vascular remodeling remain incompletely understood. Here, we present a novel model of venous arterialization in mice wherein the external jugular vein is connected to the common carotid artery.
