ABSTRACT
BACKGROUND:
Coronary stenting is one of effective and well-accepted treatments for coronary artery disease. On the other hand, side branch occlusion (SBO) is a known complication of percutaneous transluminal coronary angioplasty (PTCA) and coronary stenting. Accordingly, this study was designed to determine the incidence, predictors and acute clinical outcomes of SBO.METHODS:
Coronary angiographic findings of 45 patients who had total 98 side branches originating from the stented segments were analized before and just after coronary stenting. Bifurcation lesions were divided into 3 types type 1, type 2, type 3 and each type was subdivided into type A with significant ostial narrowing (diameter stenosis >or=50%) and type B without significant ostial narrowing of side branches. Side branch occlusion was defined as development of total occlusion or morphologic changes from type B to type A or reduction of TIMI flow more than grade 1 compared with pre-stenting flow of side branches.RESULTS:
After coronary stenting, SBO occurred in 20 of 98 side branches (20.4%). SBO was significantly related with history of previous myocardial infarction (p=0.02), threatened side branch morphology (p=0.016) and poor pre-stenting flow of side branches (p=0.014). There were no serious clinical events such as myocardial infaction and death associated with acute SBO.CONCLUSION:
Acute SBO can be developed in a few stented patients. Signifiant clinical and angiographic predictors of SBO just after coronary stenting were the history of previous myocardial infarction, threatened side branch morphology and poor pre-stenting flow of side branches.
