[Loss of a stent in the left main coronary artery and secondary migration into the left circumflex artery needing surgical extraction. Apropos of a case].
The authors report a case of accidental loss of a coronary stent in the coronary arteries and its migration into the circumflex artery. This complication occurred during revascularisation of the left anterior descending artery. In view of a dissection at the site of angioplasty and the migration of the stent, emergency surgery was undertaken comprising bypass grafting of the left anterior descending and arteriology of the left circumflex arteries to recover the stent. This is a rare complication, the frequency is probably underestimated. The authors discuss the factors predisposing to failure of implantation and the means of recovering the stents. The consequences of loss of a stent in the coronary or systemic circulations are also commented.
