Peripheral vascular atherosclerotic distributions involving especially the supra-aortic vessels are quite prevalent.
1
As a result, in patients with multivessel coronary disease including the left anterior descending (LAD) coronary artery, the left internal thoracic artery (ITA) may not be suitable as an arterial conduit because of left subclavian artery (LSA) stenosis. In such cases the alternatives are to implant a skeletonized left or right ITA graft (LITA or RITA graft), a radial artery, or a saphenous vein graft: unfortunately, all these options have a worse long-term patency rate than use of the in situ LITA.
2
To improve long-term patency rate, especially in relatively young patients, the in situ LITA can be made suitable as an arterial conduit by angioplasty and stenting of the LSA. We sought to present our preliminary experience of LSA stenting to make the LITA suitable as an arterial conduit in patients with stenosis of the LSA scheduled for surgical revascularization.
