First-in-Human Ringer™ Balloon-Assisted Coil Embolization of Large Saphenous Vein Graft Aneurysm Using the Ping-Pong Technique.

Saphenous vein graft aneurysms in patients who are at high risk for surgery can present a challenging management dilemma, particularly when large and symptomatic. We report the first-in-human use of a Ringer™ perfusion balloon catheter to facilitate percutaneous coiling of a coronary saphenous vein graft aneurysm. This technique enabled temporary occlusion of the aneurysm neck during coil embolization while maintaining distal coronary perfusion. This case highlights a novel approach to treating complex and large vein graft aneurysms, avoiding the need for covered stents or vascular plugging.
