Renal Vein Stenting via the Right Internal Jugular Approach With a Provocative Valsalva Maneuver to Reduce the Risk of Stent Migration

Abstract

An adult male with nutcracker syndrome was treated successfully by placement of a self-expanding stent in the left renal vein via a right internal jugular vein approach with a provocative Valsalva maneuver. Previous case reports have described renal vein stenting for this condition via common femoral vein approach. However, this study proposes the right internal jugular vein approach as a safer method for the treatment of nutcracker syndrome since the stent can be easily captured along the guidewire if undersized. This technique is based on the realization that the left renal vein diameter may increase by 50% to 58% during the Valsalva maneuver.
