Technologies are generally provided for a vascular reinforcement device is provided for preventing compression of a blood vessel in the presence of forces applied externally to the blood vessel. The vascular reinforcement device may include a balloon having a substantially elongated shape which may be placed adjacent to a left renal vein such that when the balloon is in an inflated position, the balloon may prevent compression of the left renal vein against a rigid structure such as the aorta. The balloon may include an anchoring sheath on each end of the balloon for anchoring the inflatable balloon to fascia surrounding the blood vessel to provide stabilization. The balloon may be delivered and positioned in an initial deflated position employing a laparoscopic procedure, and once anchored in position alongside the left renal vein, the balloon may be filled with a sterile solution for inflation.
