Background: Transjugular intrahepatic portosystemic shunt (TIPS) has emerged as a feasible therapeutic option for cirrhotic patients with portal vein thrombosis (PVT). This study aimed to assess the long-term outcomes and factors associated with TIPS dysfunction in cirrhotic patients with PVT over an 18-year period in our institution. Methods: A retrospective study was conducted at Hospital Universitario Reina Sofía (Córdoba, Spain), including adult and pediatric cirrhotic patients with PVT who underwent TIPS between January 2006 and December 2024. Patient characteristics, procedural techniques, and clinical outcomes were evaluated. The primary outcomes were TIPS insertion success rate, primary patency, and dysfunction (stenosis or occlusion). Bivariate comparisons, logistic regression and receiver-operating characteristic (ROC) analyses were performed to identify potential predictors of TIPS dysfunction. Survival analyses using the Kaplan–Meier method and log-rank test, complemented by Cox regression, were also conducted. Results: A total of 36 patients (mean age, 44.8 ± 20.1 years old; 22.2% women; 19.4% children) were included, with a mean follow-up of 66.3 ± 45.9 months and nine deaths (one attributable to the procedure). The primary success rate of TIPS placement was 100%, and mean primary patency was 40.3 ± 40.2 months. TIPS dysfunction occurred in 30.3% of patients. Logistic regression identified age as the only significant predictor of TIPS dysfunction (OR = 0.949; 95%CI, 0.907–0.985, p = 0.011). ROC analysis demonstrated an AUC of 0.737 (95%CI, 0.547–0.927), with an optimal age cut-off of 21 (equivalent to 18 years; sensitivity = 91.3%, specificity = 50%). When age was dichotomized into adult versus pediatric groups, the OR was 0.095 (95%CI, 0.011–0.560), consistent with survival analyses (log-rank p = 0.007; HR = 4.85; 95%CI 1.36–16.88, p = 0.015). Conclusions: TIPS is an effective treatment for cirrhotic patients with PVT, achieving high technical success and long-term patency. However, it is not exempt from complications, including death, and potential dysfunction remains a concern, particularly in pediatric patients. Further prospective studies with larger cohorts are warranted to refine patient selection and optimize outcomes.

Interventional radiology (IR) has evolved rapidly, but the clinical integration of interventional radiologists has not kept pace with technical advancements. This trial will address a gap in the literature by providing a robust investigation into specific measures for enhancing the clinical role of interventional radiologists, with potential implications for improving patient experiences and outcomes. The single-center randomized controlled trial will include 428 patients undergoing IR procedures. The control group will receive information about the procedure from the ordering physician, while the experimental group will have an additional consultation with an interventional radiologist and be shown procedure-specific explanatory videos. The primary outcomes are patients’ knowledge, satisfaction with the information and communication, and anxiety. Data collection will involve specific questionnaires and scales. This trial is designed to investigate the importance of proactive clinical roles in patient care within IR. The study explores the potential of consultations and audiovisual tools, highlighting their role in educating patients about procedures. The results may help foster a more widespread acceptance of clinical responsibilities in IR and underscore the pivotal role of audiovisual aids in patient education and satisfaction. Trial registration NCT05461482 at clinicaltrials.gov. Relevance statement This randomized controlled trial will assess the impact of clinical consultations and explanatory audiovisual tools on patient understanding, satisfaction, and anxiety in interventional radiology. The findings could help establish a more proactive clinical role for interventional radiologists and improve the overall quality of patient-centered care. Key Points We describe the protocol of an interventional radiology randomized clinical trial. The control group will receive procedure information from the referring physician and the experimental group receives additional consultation with interventionalists and views a video. Knowledge, satisfaction with information, and patient anxiety will be evaluated. This study will provide insights about the benefits of consultations and videos in interventional radiology.
