“…Recently, our group has reported IVUS predictors of TLR after self-expanding nitinol stent implantation in the superficial femoral artery (SFA) [28]. In line with previous our findings, reporting self-expanding nitinol stent implantation in the SFA lesions, the current study showed that stent edge dissection was the independent predictor of TLR after self-expanding nitinol stent implantation for the iliac artery lesion.…”

“…The precise reason for the discrepancy between the previous reports and our study is unclear; however, it may possibly relate to the difference in type of stent implanted (balloon-expandable stainless steel stent versus self-expandable nitinol stent) and arterial size (the coronary artery versus the iliac artery). It has been reported that deep medial edge dissection, not intimal edge dissection, is a risk of TLR after EVT with self-expanding stent [28]. This suggests that continuous force exerted against the vessel wall after deep edge dissection may have induced additional arterial damage, suggesting the possibility of intimal hyperplasia.…”

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 with >50 % angiographic stenosis of the target lesion. The 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 < 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 < 0.01) and stent edge dissection (OR = 10.4, p < 0.01) were independent IVUS predictors of TLR. Receiver-operating characteristic analysis identified post-procedural MSA <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.

“…A recent report revealed that stent implantation in a tiny vessel, stent edge dissection, and total stent length were independent predictors of target lesion revascularization after implantation of a self-expandable nitinol stent for SFA lesions 17) . These findings closely resemble the results of previous IVUS studies for CAD.…”

Aim:The optimal fractional flow reserve (FFR) measurement method for superficial femoral artery (SFA) lesions remains to be established. We clarified the optimal measuring procedure for FFR for SFA lesions and investigated the necessary dose of papaverine for inducing maximal hyperemia in SFA lesions. Methods: Forty-eight patients with SFA lesions who underwent measurement of peripheral FFR (pFFR: distal mean pressure divided by proximal mean pressure) after endovascular treatment by the contralateral femoral crossover approach were prospectively enrolled. In the pFFR measurement, a guide sheath was placed on top of the common iliac bifurcation and pressure equalization was performed. After advancing the pressure wire distal to the SFA lesion, sequential papaverine administration selectively to the affected common iliac artery was performed.
