CONCLUSION The presence of CAD and heart failure were associated with mortality in patients with PAD. The prognostic impact of CAD and LVEF appears different between patients with IC and CLI. TCTAP A-117 Impact of Stent Diameter on Stent Patency After Self-Expanding Paclitaxel-Eluting Stent Implantation in the Superficial Femoral Artery: An Optical Frequency Domain Imaging Study Kojiro Miki,1 Kenichi Fujii,1 Tetsuo Horimatsu,1 Tohru Masuyama,1 Masaharu Ishihara2 1 Hyogo College of Medicine, Japan; 2National Cerebral and Cardiovascular Center, Japan BACKGROUND Reports describing the influence of stent diameter on stent patency after self-expanding paclitaxel-eluting stent (PES) implantation in the superficial femoral artery (SFA) have been limited. METHODS A total of 20 de novo SFA lesions were randomized 1:1 to receive either PES with a diameter of 6-mm or 8-mm. Follow-up angiography and optical frequency domain imaging (OFDI) was scheduled six months after stent implantation, and volumetric OFDI analysis was performed to evaluate vascular response to the stents. Volume index (VI) was defined as volume divided by stent length. The primary end point was lumen VI at 6-months follow-up. Secondary end point was minimum lumen diameter (MLD) by quantitative vascular angiography at the follow-up. RESULTS Patient and lesion characteristics were similar between the two groups. Baseline reference vessel diameter was 4.3 1.0 mm in the 6-mm group and 4.4 0.9 mm in the 8-mm group (p ¼ 0.86). MLD immediately after stent implantation was similar between the two groups (4.2 0.5 mm in the 6-mm group and 3.7 0.7 mm in the 8mm group, p ¼ 0.27). At the 6-month follow-up, MLD was larger in the 8-mm group compared to the 6-mm group (4.1 0.4 mm vs. 3.3 0.4 mm, p<0.01). Stent, neointimal, and lumen VI at the follow-up are summarized in Figure. Stent VI and lumen VI were greater in the 8-mm group compared to the 6-mm group.

We divided into combined stent group (balloon-expandable nitinol stenting for common iliac artery/self-expandable nitinol stent for external iliac artery and double self-expandable nitinol stent group). Outcome measures were primary patency (PP), secondary patency (SP) and major adverse limb events (MALE; any repeat revascularization for limb and leg amputation). RESULTS At 7 years, no significant difference was observed in PP, SP and freedom from MALE. On multivariate analysis, female gender, dyslipidemia and age>75 were found to be independent predictors of primary patency for de-novo long AI lesion. There are no difference between two groups in PP (hazard ratio, 0.64,95% confidential interval. 0.18-2.10; adjusted P¼0.47), SP (hazard ratio, 3.48,95% confidential interval. 0.32-37.8; adjusted P¼0.28) and freedom from MALE (hazard ratio,0.75,95% confidential interval. 0.39-1.43; adjusted P¼0.38). CONCLUSION PP, ASP, AP and freedom from MALE showed no significant difference between two groups. Dyslipidemia, age>75 and female gender were found to be independent predictors of primary patency for long AI disease. TCTAP A-119 The Incidence of Critical Limb Ischemia and Major Amputation of Claudicants Undergoing Endovascular Therapy Yukiko Matsumura,1 Yoshimitsu Soga,1 Kenji Ando1 1 Kokura Memorial Hospital, Japan BACKGROUND The incidence of critical limb ischemia (CLI) and major amputation of claudicants after endovascular therapy (EVT) for femoropopliteal (FP) lesions was unclear. METHODS A total of 1073 limbs of 835 claudicants (604 men; mean age 72.88.5 years) underwent EVT for FP lesions between January 2004 and December 2013 were enrolled, retrospectively. Outcome measures were the incidence of CLI and major amputation. Mean follow-up period was 5131 months. RESULTS The incidence of CLI and major amputation at 5-year were 7.9% and 1.7%. On multivariate analysis, elderly age (>75 years), BMI<18, diabetes, hemodialysis, heart failure were independent predictors of CLI. EVT wasn’t associated with the development of CLI.
CONCLUSION Chronic stent enlargement resulted in significantly greater lumen area after implantation of PES with a diameter of 8-mm. This result proposes that stent diameter might be important for stent patency in procedure with self-expanding PES in the periphery. TCTAP A-118 A Comparison of Combined Balloon Expandable and Self-Expandable Nitinol Stent vs Double Self-Expandable Nitinol Stents for Long Aorto-Iliac Disease Yasuaki Takeji,1 Yoshimitsu Soga,1 Kenji Ando1 1 Kokura Memorial Hospital, Japan BACKGROUND The aim of this study was to compare the outcomes of balloon-expandable/self-expandable initial stent and double selfexpandable nitinol stents) for long aorto-iliac (AI) disease. METHODS From November 2005 to March 2015, 1160 patients (915 male, 1555 limbs) underwent endovascular therapy for AI lesion. 191 consecutive patients (210 limbs, mean age 73, 77% male) implanted two stents for de-novo long AI lesion.) and were analyzed retrospectively.
CONCLUSION Incidence of CLI and major amputation of claudicants after EVT for FP lesion were feasible.
