RESUMO
Objective To analyze the consistency between computer tomography angiography(CTA)and digital subtraction angiography(DSA)in evaluating the global limb anatomic staging system(GLASS)stage of patients with chronic limb-threatening ischemia(CLTI).Methods The clinical data of patients with CLTI,who were admitted to the First Affiliated Hospital of Xi'an Jiaotong University of China to receive treatment between January 2017 and December 2020,were retrospectively analyzed.Taking the DSA assessment as the gold standard,the consistency of CTA and DSA in evaluating the GLASS stage of patients with CLTI was analyzed.Results In the assessment of GLASS stage of CLTI,CTA showed strong agreement with DSA.The weighted Kappa coefficient of CTA and DSA for the staging of femoropopliteal segment was 0.798(95％CI=0.722-0.873,P＜0.01),and the weighted Kappa coefficient of CTA and DSA for the staging of infrapopliteal artery segment was 0.785(95％ CI=0.725-0.845,P＜0.0l).For the overall staging of GLASS,the weighted Kappa coefficient of CTA and DSA was 0.832(95％ CI=0.752-0.91 1,P＜0.01).All the above results indicated that a very strong consistency existed between CTA and DSA in evaluating the GLASS stage of patients with CLTI.Conclusion CTA examination of lower limb can accurately evaluate GLASS score and stage of CLTI patient's target lesions,which is helpful in diagnosing lower extremity arteriosclerosis occlusion disease as well as in assessing the technical difficulty degree of its revascularization operation.(J Intervent Radiol,2024,33:300-303)
RESUMO
@#Objective: To explore the balance of peripheral blood T helper 17 cells/regulatory T cell (Th17/Treg) ratio and the polarization ratio of M1 and M2 macrophages in lower extremity arteriosclerosis obliterans (ASO). Methods: A rat model of lower extremity ASO was established, and blood samples from patients with lower extremity ASO before and after surgery were obtained. ELISA was used to detect interleukin 6 (IL-6), IL-10, and IL-17. Real-time RCR and Western blot analyses were used to detect Foxp3, IL-6, IL-10, and IL-17 expression. Moreover, flow cytometry was applied to detect the Th17/Treg ratio and M1/M2 ratio. Results: Compared with the control group, the iliac artery wall of ASO rats showed significant hyperplasia, and the concentrations of cholesterol and triglyceride were significantly increased (P<0.01), indicating the successful establishment of ASO. Moreover, the levels of IL-6 and IL-17 in ASO rats were pronouncedly increased (P<0.05), while the IL-10 level was significantly decreased (P<0.05). In addition to increased IL-6 and IL-17 levels, the mRNA and protein levels of Foxp3 and IL-10 in ASO rats were significantly decreased compared with the control group. The Th17/Treg and M1/M2 ratios in the ASO group were markedly increased (P<0.05). These alternations were also observed in ASO patients. After endovascular surgery (such as percutaneous transluminal angioplasty and arterial stenting), all these changes were significantly improved (P<0.05). Conclusions: The Th17/Treg and M1/M2 ratios were significantly increased in ASO, and surgery can effectively improve the balance of Th17/Treg, and reduce the ratio of M1/M2, and the expression of inflammatory factors.
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.
