title: Short stent implantation for routine use is feasible in a high proportion of coronary interventions and yields a low restenosis rate.
abstract: Stent length predicts restenosis. The feasibility of using a short stent (<10 mm) routinely was investigated in 331 consecutive patients treated for 424 coronary artery lesions. A single short stent provided suitable coverage and achieved a residual stenosis <30%, with or without predilatation, in 252/424 lesions (59.4%). Longer stents were implanted in 58/424 lesions (13.7%), while only percutaneous transluminal coronary angioplasty was performed in 114/242 lesions (26.9%). Angiographic success and procedural success were achieved in 250/252 lesions (99.2%). Restenosis occurred in 36/231 lesions (15.6%) after short stenting, in 10/53 lesions (18.9%) after long stents, in 21/88 lesions (23.9%) after percutaneous transluminal coronary angioplasty, and in 67/372 lesions (18.0%) controlled angiographically. Only small vessel diameter predicted restenosis after short stenting. Thus, a single short stent implanted directly or after predilatation is sufficient to achieve an acceptable angiographic result in more than in nearly 60% of all treated lesions. Short stenting results in a low restenosis rate.
