Key result
Drug-eluting and covered stent implantation successfully restored antegrade TIMI 3 flow after failed aspiration and laser thrombectomy in a patient with LIMA graft thrombosis.
Why the study?
Acute occlusion of the LIMA graft late after coronary artery bypass grafting surgery is a rare and potentially life-threatening complication.
Case Report (n=1)
This case highlights the challenges of treating late LIMA graft thrombosis and demonstrates successful management of laser-induced perforation with covered stent implantation.
Late LIMA occlusion carries perforation risk with laser thrombectomy; leaves open optimal endovascular strategy for this rare entity.
Acute occlusion of the left internal mammary artery (LIMA) graft late after coronary artery bypass grafting surgery is a rare and potentially life-threatening complication. We describe a case of acute myocardial infarction 19 years after coronary artery bypass graft surgery due to acute occlusion of the distal anastomosis of a LIMA graft to the left anterior descending artery. Aspiration thrombectomy failed to remove the thrombus. Laser thrombectomy caused perforation. After drug-eluting and covered stent implantation, antegrade TIMI 3 flow was restored with an uneventful postprocedural course.

Xenogiannis et al. (2019) conducted a case report in Acute myocardial infarction due to LIMA graft thrombosis (n=1). Aspiration thrombectomy, laser thrombectomy, and stent implantation was evaluated on Restoration of TIMI 3 flow. Drug-eluting and covered stent implantation successfully restored antegrade TIMI 3 flow after failed aspiration and laser thrombectomy in a patient with LIMA graft thrombosis.
