Abstract: Background: Data on the outcomes of stent implantation in long lesions (≥28 mm) in small (≤2.5 mm) coronary vessels is limited.Aim: To investigate the acute outcomes of stenting in long and small coronary lesions. Study Design: Retrospective cohort study.Methods: Patients with stable coronary artery disease or acute coronary syndrome (ACS) who had undergone percutaneous coronary revascularization to native coronary arteries with stents ≤2.5 mm in size and ≥28 mm in length were assessed.Post-procedural analyses were performed with using Quantitative Coronary Analysis software system to evaluate stent oversizing.Acute complications, such as edge dissection and distal thrombus embolism were also recorded.Results: A total of 161 consecutive patients (127 male, mean age: 62.7±9.0 years) were included.Most of the lesions were mid or proximal segments of the coronary arteries.Edge dissection was detected in 30 patients.Stent oversizing and reduced post-procedural TIMI flow grade were significantly higher in patients with edge dissection.Stent oversizing emerged as an independent predictor of edge dissection, with oversizing of >25% compared to the distal vessel diameter predicted edge dissection with a sensitivity of 83.3% and specificity of 80.2%.In addition to edge dissection, distal embolism was more frequently observed in procedures with stent oversizing.TIMI flow grade 1-2 rates were found to be significantly higher in patients presenting with ACS.Conclusion: Stenting in long lesions with small sized stents is related to a high risk of edge dissection, especially in procedures involving stent oversizing.
