Papers・Description | UNASSIGNED:Although intravascular ultrasound (IVUS) predictors of stent patency for the coronary artery lesion have been established, little is known about IVUS predictors of stent patency for the aorto-iliac artery lesion. We analyzed 154 lesions of 122 patients who underwent stent implantation for iliac artery lesions. Quantitative and qualitative IVUS analyses were performed for pre- and post-procedural IVUS imaging in all lesions. Target lesion revascularization (TLR) was defined as clinically driven revascularization withUNASSIGNED:>UNASSIGNED:50 % angiographic stenosis of the target lesion. TheUNASSIGNED:mean follow-up period was 39 ± 16 months. TLRs were performed in 13 lesions (8.4 %). Post-procedural minimum stent area (MSA) was significantly smaller in the TLR group compared to the no-TLR group (16.0 ± 5.8 vs. 25.6 ± 8.5 mm(2), p UNASSIGNED:<UNASSIGNED: 0.001). Stent edge dissection was frequently observed in the TLR group compared to the no-TLR group (53.8 vs. 24.1 %, p = 0.04). Multivariate analysis revealed that post-procedural MSA (OR = 0.76, p UNASSIGNED:<UNASSIGNED: 0.01) and stent edge dissection (OR = 10.4, p UNASSIGNED:<UNASSIGNED: 0.01) were independent IVUS predictors of TLR. Receiver-operating characteristic analysis identified post-procedural MSAUNASSIGNED:<UNASSIGNED:17.8 mm(2) as the optimal cut-point for the prediction of TLR (AUC = 0.846). Post-procedural MSA and stent edge dissection could predict long-term stent patency in the iliac artery lesion. Our results propose that adequate stent enlargement without edge dissection might be important to reduce TLR in the iliac artery lesion. |
