title: Retrograde coronary angioplasty of isolated arterial segments through saphenous vein bypass grafts.
abstract: Progression of native coronary artery disease proximal to the placement of saphenous vein grafts may leave arterial segments isolated by stenoses on either side. In 16 patients, we attempted coronary angioplasty in a retrograde direction through saphenous vein grafts to revascularize 17 isolated arterial segments. The retrograde dilatation was successful in 12 of 17 attempts (71%). Failure in 5 attempts was due to severe angulation between the graft insertion site and the retrograde proximal arterial limb. There were no major complications of these procedures. Symptoms and signs of myocardial ischemia were relieved following successful retrograde dilatation. Thus, retrograde dilatation through saphenous vein grafts provides another means of achieving complete revascularization using coronary angioplasty in patients with prior coronary bypass surgery.
