Among them, 50 patients who underwent traditional segmental angiography were assigned to the control group, while 45 patients who underwent stepping angiography were assigned to the observation group. Comparative assessments were performed between the two groups regarding image quality, angiography time, absorbed radiation dose, contrast agent dosage, and incidence of complications.ResultsThe image quality in the observation group was better than that in the control group. The average angiography time in the control group was 27.87 ± 4.98 min, while that in the observation group was 10.23 ± 2.88 min (<i>P </i>=<i> </i>0.013). The average absorbed radiation dose in the control group was 4.65 ± 1.32 Gy, while that in the observation group was 3.53 ± 0.73 Gy (<i>P </i>=<i> </i>0.008). The average contrast agent dosage in the control group was 69.42 ± 10.42 mL, while that in the observation group was 47.51 ± 8.14 mL (<i>P </i>=<i> </i>0.011). Two complications occurred in the control group, while three occurred in the observation group (<i>P </i>=<i> </i>0.339).ConclusionFor lower limb venous lesions, stepping angiography is superior to traditional segmental angiography in terms of overall image quality and practicality. Stepping angiography is a simpler and quicker process, and only a small dose of radiation is absorbed by both doctors and patients; moreover, it requires a lower dosage of contrast agent. It plays an important objective guiding role in the decision-making of treatment plans for lower limb venous diseases.</p>","PeriodicalId":16129,"journal":{"name":"Journal of International Medical Research","volume":"53 7","pages":"3000605251361099"},"PeriodicalIF":1.5,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144742194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, more than half of the patients experience poor outcomes despite successful recanalization, which was defined as futile recanalization. The present study aimed to identify the relationship between multiple inflammatory markers (before and after endovascular treatment) and futile recanalization.MethodsBetween November 2019 and September 2022, we retrospectively enrolled 456 patients according to the inclusion and exclusion criteria. Inflammatory variables, including neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, systemic immune-inflammation index, systemic inflammatory response index, systemic coagulation-inflammation index, and white blood cell count to mean platelet volume ratio, were collected.ResultsAmong the cohort of 456 patients, it was observed that 271 (59.4%) patients experienced futile recanalization. Univariate analysis revealed that patients with futile recanalization had higher neutrophil-to-lymphocyte ratio and systemic inflammatory response index but lower lymphocyte-to-monocyte ratio and systemic coagulation-inflammation index at admission compared with those without (p < 0.05). Additionally, at postoperation, patients with futile recanalization had higher neutrophil-to-lymphocyte ratio, systemic inflammatory response index, and systemic immune-inflammation index but lower lymphocyte-to-monocyte ratio and systemic coagulation-inflammation index compared with those without (p < 0.05). However, there were no significant differences in admission platelet-to-lymphocyte ratio, admission systemic immune-inflammation index, admission white blood cell count to mean platelet volume ratio, postoperation platelet-to-lymphocyte ratio, and postoperation white blood cell count to mean platelet volume ratio between the futile recanalization group and nonfutile recanalization group (p > 0.05). Furthermore, multivariate logistic regression analysis showed that only admission systemic inflammatory response index, postoperation neutrophil-to-lymphocyte ratio, postoperation systemic inflammatory response index, and postoperation systemic immune-inflammation index remained significantly correlated with futile recanalization (p < 0.05). Receiver operating characteristic curves revealed that postoperation neutrophil-to-lymphocyte ratio was the most predictive marker for futile recanalization (area under the curve = 0.623, 95% confidence interval: 0.572-0.675).ConclusionAdmission systemic inflammatory response index, postoperation neutrophil-to-lymphocyte ratio, postoperation systemic inflammatory response index, and postoperation systemic immune-inflammation index were independently associated with futile recanalization, and postoperation neutrophil-to-lymphocyte ratio may have the highest ability in predicting futile recanalization in patients who underwent endovascular trea","PeriodicalId":16129,"journal":{"name":"Journal of International Medical Research","volume":"53 7","pages":"3000605251359474"},"PeriodicalIF":1.5,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144742195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
