RESUMO
Objective To compare the effect and safety of stenting versus directional atherectomy (DA) in the treatment of TASCⅡ A and B superficial femoral artery lesions.Methods 100 patients with TASC Ⅱ A and B lesions were divided into percutaneous transluminal stenting(PTS) group (n =50) and DA group (n =50).Patients were compared in terms of technical success rate,treatment success rate,first operation cost,postoperative ankle brachial index (ABI),limb salvage rate,survival,and patency.Results The technical success rate in both PTS and DA group was 100％.The treatment success rate was 98％ vs.86％,P＞0.05.Postoperative ABI:0.82 ±0.19 vs.0.80 ±0.27,P＞0.05.First operation cost:(34 820 ± 1 051) yuan vs.(45 635 ± 1 358) yuan,P ＜0.001;All patients were followed-up for up to 2-year,the cumulative patency rate was 81.6％ vs.72.9％ (P＞0.05).Limb salvage rate was 97.9％ vs.93.8 ％,P ＞ 0.05.Conclusion There were no significant differences in the effect and safety of PTS versus DA in the treatment of TASCⅡ A and B superficial femoral artery lesions.
RESUMO
Objective@#To investigate the correlation between the stenosis degree of superior mesenteric artery (SMA) and each artery within the scope of aorto-iliac artery in patients with lower extremity atherosclerotic occlusive disease (LEAOD).@*Methods@#Images of 70 patients who had undergone the aorta-iliac-femoral arteries CT angiography (CTA) examination and had a definite diagnosis of LEAOD due to intermittent claudication or resting pain admitted to Tianjin Hospital from January to December in 2017 were enrolled. The arteries in the aorta as well as iliac were surface-reconstructed, which were analyzed by advanced vascular analysis (AVA) combined with the original images, including SMA trunk, abdominal aorta (AA), left and right common iliac artery (LCIA, RCIA), left and right internal iliac artery (LIIA, RIIA), left and right external iliac artery (LEIA, REIA). The normal reference plane and the maximal stenosis plane were selected, and the stenosis rate of each artery in the reconstruction range was automatically calculated with software. The patient's imaging data were divided into groups with two methods: ① according to the degree of SMA stenosis, the patients were divided into group Ⅰ (stenosis degree ≤70%) and groupⅡ (stenosis degree > 70%); ② LEAOD patients with different gender were respectively divided into three groups: middle-aged group (45-59 years old), pre-elderly group (60-74 years old) and elderly group (75-89 years old). The comparison between the stenosis degree of SMA and each artery within the scope of aorto-iliac artery was analyzed with Pearson simple correlation analysis.@*Results@#The incidence of SMA stenosis in all LEAOD patients was 100%. Correlation analysis showed that there was no correlation between the stenosis degree of SMA and AA, LCIA, RCIA, LIIA, RIIA, LEIA, or REIA in group Ⅰ (n = 64) and group Ⅱ (n = 6), respectively (r value was -0.021, 0.023, 0.023, -0.137, 0.182, -0.113, 0.141, respectively, in group Ⅰ, and it was 0.020, -0.560, 0.010, 0.306, -0.204, -0.381, 0.393, respectively, in group Ⅱ, all P > 0.05). In 52 male patients, there was no correlation between the stenosis degree of SMA and AA, LCIA, RCIA, LIIA, RIIA, LEIA, or REIA in middle-aged group (n = 16), pre-elderly group (n = 27) and elderly group (n = 9), respectively (r value was -0.032, 0.024, 0.324, 0.146, 0.312, 0.008, 0.344, respectively, in middle-aged group, it was -0.108, -0.116, -0.040, -0.249, -0.082, -0.052, 0.096, respectively, in pre-elderly group, and it was 0.182, 0.311, 0.400, 0.360, 0.688, 0.498, 0.406, respectively, in elderly group, all P > 0.05). In 18 female patients, there was also no correlation between the stenosis degree of SMA and above each artery within the scope of aorto-iliac artery in pre-elderly group (n = 11) and elderly group (n = 6), respectively (the r value was -0.170, 0.040, -0.019, 0.152, 0.508, 0.042, 0.456, respectively, in pre-elderly group, and it was -0.660, 0.008, -0.055, -0.056, -0.213, 0.344, 0.011, respectively, in elderly group, all P > 0.05). The correlation in middle-aged group was not analyzed because there was only 1 patient.@*Conclusions@#Although the atherosclerotic changes in LEAOD patients can affect SMA and aorto-iliac artery at the same time, there was no correlation between the stenosis degree of SMA and each artery within the scope of aorto-iliac artery which may due to the differences in the histological structure and hemodynamics among different arteries. SMA atherosclerotic stenosis and occlusion is a relatively independent disease process for LEAOD.

Objective To investigate methods and results of endovascular treatment in TASC (Ⅱ) D-type femoral artery occlusion. Methods From January 2012 to May 2013, 26 cases (26 branches) of superficial femoral artery occlusion with endovascular treatment of TASC (Ⅱ) D-type superficial femoral artery occlusion were retrospectively reviewed. The effi-cacy was evaluated through ABI, CTA, DSA and symptoms improved. Results 26 branches were treated with endovascular methods. Technical success rate was 80.7%(21/26), including 13 branche with stent implantation, 6 branches with Silver-hawk atherectomy and 2 branches with Viabahn stent implantation. All patients were followed up for a mean period of (10.3 ± 1.2)months, primary patency rates at 6 months were 69.2%in stent group, 66.7%in Silverhawk atherectomy group and 100%in Viabahn stent group. Conclusion Endovascular treatment of TASC (Ⅱ) D-type femoral artery occlusion can lead to satisfactory short term patency rates, and Viabahn stent is the latest treatment.
