Drug eluting stent induced coronary artery aneurysm repair by exclusion. Where are we headed?
We present a case of left anterior descending (LAD) coronary artery aneurysm at the site of previous stent placement 3 years previously. The patient presented with recent worsening of angina. Angiography and 64 slice CT angiography confirmed the presence of 6mm aneurysm of LAD at the site of previous stent involving the origin of diagonal, with thrombus proximal and distal to the stent. This patient was successfully managed by taking the posterior wall of the anterior descending artery while suturing the heel of the left internal mammary artery (LIMA)-LAD anastomosis. The idea was to create severe stenosis upstream to prevent distal embolisation from the site of aneurysm. The diagonal was grafted with a saphenous venous graft. Follow-up angiogram at 3 months demonstrated successful exclusion of the aneurysm and unobstructed flow through the grafts.
