Abstract

We report an unusual complication of a 25 mm long stent, which did not expand at all for 1 mm in its proximal segment, while rest of the 24 mm length of the stent got fully expanded. Repeated attempts to expand the extremely focal unexpanded part of the stent at high pressure led to rupture of the stent balloon and its entrapment. We failed to retrieve the balloon using various techniques and the patient had to be sent for coronary artery bypass graft surgery.
