Key result
Coronary stenting is linked to ~5% acute side branch occlusion and complete long-term patency.
Why the study?
Adverse effects related to coronary stent implantation are not completely known, with side branch occlusion from mechanical obstruction or thrombosis representing an important potential complication.

Does Palmaz-Schatz stent placement affect the patency of lesion-associated side branches in patients undergoing coronary angioplasty?
Coronary stenting rarely causes acute side branch occlusion, and when it does, it is associated with baseline ostial disease, with excellent long-term patency.
Fischman et al. (1993) conducted an observational in Coronary artery lesions requiring stenting (n=153). Palmaz-Schatz stent placement was evaluated on Immediate and long-term patency of lesion-associated side branches. Coronary stenting rarely caused acute side branch occlusion (5%), which was associated with intrinsic ostial disease, and 100% of branches were patent at 6-month follow-up.
