Retained Coronary Balloon Requiring Emergent Open Surgical Retrieval: An Uncommon Complication Requiring Individualized Management Strategies

The entrapment of coronary intervention devices within the coronary vasculature is a rare but potentially devastating procedural complication. We report a case of an entrapped balloon and broken shaft that had to be retrieved by an open surgical approach. When device extraction is indicated and the use of snaring equipment is unsuccessful or inappropriate, a number of alternative percutaneous maneuvers can be attempted. These include (1) simple advancement and withdrawal of a trapped balloon, (2) use of a “buddy” wire to straighten the vessel and free the trapped device, (3) inflation of a buddy balloon adjacent to a trapped primary balloon to free the device, (4) partial inflation of a buddy balloon distal to a trapped device followed by gentle withdrawal, (5) use of an in-guide secondary balloon to trap the lost device, (6) advancement and twisting of guidewires to entwine the lost device, (7) saline dilution of trapped balloons, and (8) anchoring balloon and reverse-wire puncture of an undeflated and entrapped primary balloon. Careful consideration of various device retrieval strategies is indicated before resorting to open surgical retrieval in the rare instance of intracoronary device entrapment.
