complication of coronary angioplasty leading to surgical emergency: a case report

Dislodgement of coronary stent-balloon catheter before deployment during percutaneous coronary intervention though rare but life threatening complication. A 47-year-old male presented with history of angina for two years. Angiography revealed that there was a stenosis [90%] in the left anterior descending [LAD] artery and significant plaque in the circumflex artery. During PTCA a stent-balloon was dislodged in left main coronary artery [LMCA]. Under cardiopulmonary bypass, with cardioplegic arrest, the stentballoon-catheter was extracted through coronary arteriotomy with repair of ruptured LMCA. Coronary revascularization was done with reversed saphenous vein grafts to the LMCA and D1 coronary arteries
