The study compared the outcomes of the drug-within-drug (DWD) strategy, ie, combining DES for failed vessel preparation segments and DCB for successful ones, with those of full DES implantation.

The \"Drug-with-Drug\" (DWD) strategy, which involves implanting DES only at sites with severe dissection or residual stenosis after pre-balloon dilation and using drug coated balloons (DCB) for segments successfully prepared without stenting, has shown comparable outcomes to full stent coverage.

The primary outcomes were factors associated with non-revascularization and mortality rate.</p><p><strong>Results: </strong>A total of 133 patients were enrolled in this study. Univariable analysis revealed significant associations between non-revascularization and diabetes (hazard ratio [HR]=2.61, 95% confidence interval [CI], p=0.03), chronic kidney disease (HR=16.2, 95% CI, p=0.01), and severe calcifications (HR=8.56, 95% CI, p<0.001). Subsequent multivariable analysis confirmed the significance of these factors, showing HRs of 3.04 (95% CI, p=0.02), 13.12 (95% CI, p=0.03), and 8.62 (95% CI, p<0.001), respectively. The overall mortality rate observed was 20.3%. Severe calcifications emerged as a significant risk factor for mortality in both univariable (HR=2.47, 95% CI, p=0.02) and multivariable (HR=3.01, 95% CI, p<0.001) analyses.</p><p><strong>Conclusion: </strong>Severe calcifications correlate with non-revascularization and mortality, while comorbidities like diabetes mellitus and chronic kidney disease are also associated with non-revascularization. Recognizing these identified factors holds substantial promise in enhancing patient selection and procedural approaches, potentially bolstering the success rates of endovascular interventions. However, further research aimed at comprehending the underlying mechanisms and devising strategies to mitigate these risks is imperative for continued improvement in patient outcomes.</p><p><strong>Clinical impact: </strong>The study provides valuable insights into patient selection and procedural planning for endovascular interventions in TASC II A/B iliac artery occlusions. Identifying severe calcifications, diabetes, and chronic kidney disease as key risk factors for non-revascularization and mortality equips clinicians with essential predictive tools, potentially improving outcomes by tailoring treatment approaches. The innovation lies in highlighting the impact of comorbidities and calcification severity, offering a pathway to refine patient eligibility criteria and optimize procedural decisions. This underscores the importance of further research to develop strategies that mitigate these risk factors and enhance intervention success rates.</p>","PeriodicalId":50210,"journal":{"name":"Journal of Endovascular Therapy","volume":" ","pages":"15266028241296482"},"PeriodicalIF":1.7,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142631877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
