Key result
Stenting of the aorto-ostial lesion of the saphenous vein graft followed by retrograde dilatation successfully reopened the totally occluded ostial left anterior descending artery and eliminated ischemia.
Case Report (n=1)
Retrograde dilatation via a saphenous vein graft can successfully reopen a totally occluded ostial left anterior descending artery and eliminate ischemia.

May support retrograde SVG dilatation for select occluded ostial LAD cases; leaves open generalizability and safety beyond this report.
Treatment of native coronary and saphenous vein graft aorto-ostial stenoses with balloon angioplasty is associated with lower procedural success rates and more complications compared with percutaneous transluminal coronary angioplasty of nonostial stenoses. A patient with totally occluded ostial left anterior descending artery at ostium following aortocoronary bypass developed ostial stenosis at the saphenous vein graft in the descending aorta. The aorto-ostial lesion of saphenous vein graft was successfully stented and was followed by retrograde dilatation of the left anterior descending artery, and the totally occluded ostial lesion was reopened. The ischemia was eliminated following the procedure.

Cheng et al. (2003) conducted a case report in Totally occluded ostial left anterior descending artery and aorto-ostial graft restenosis (n=1). Stenting of aorto-ostial lesion followed by retrograde dilatation was evaluated on Procedural success and elimination of ischemia. Stenting of the aorto-ostial lesion of the saphenous vein graft followed by retrograde dilatation successfully reopened the totally occluded ostial left anterior descending artery and eliminated ischemia.
