A method for facilitating treatment of catheter induced vascular injuries may first involve introducing a guide wire into a vascular sheath residing in a blood vessel, where the guide wire has a distal end and an inflatable balloon at least 15 cm proximal of the distal end. The method may further involve proximally retracting the vascular sheath while leaving the wire in place and observing indicia of the presence or absence of a vascular injury caused to the blood vessel by the vascular sheath or a procedural catheter previously advanced through the vascular sheath. If indicia of a vascular injury are observed, the method may involve positioning the inflatable balloon at or near the vascular injury and inflating the balloon to reduce blood flow past the vascular injury, while leaving the guide wire in place to provide subsequent access to the injury.
