Abstract

Stent migration from the delivery balloon catheter is a rare but serious complication during percutaneous coronary intervention, particularly when a part of the stent stretches into the aorta. We report an unusual case of stent migration treated with a combination of a gooseneck snare and rotablation. A part of the stent was overstretched and unrolled into the aorta and the rest of the stent remained implanted in the coronary artery. The stent was captured with a gooseneck snare but could not be retrieved because it was connected to a stent remnant implanted in the coronary artery. The stent strut was cut with rotablation, and the stent was successfully removed through the femoral sheath.
