{"title":"Intravascular ultrasound guidance in superior vena cava stenting for malignant superior vena cava obstruction: solving the landing zone dilemma.","authors":"Renata Kiri Mak, Hon Shing Fung, Keith Wan Hung Chiu, Wai Lun Poon","doi":"10.4274/dir.2026.263872","DOIUrl":"https://doi.org/10.4274/dir.2026.263872","url":null,"abstract":"<p><strong>Purpose: </strong>Patients with superior vena cava (SVC) obstruction (SVCO) are referred for stenting to alleviate symptoms such as plethora and dyspnea. Accurate visualization and measurement of the central veins are essential for appropriate stent selection and optimal placement. This is critical to avoid extension into the right atrium, which can lead to arrhythmias or stent migration. However, in cases of severe SVCO, the sinoatrial junction (SAJ) often cannot be opacified on angiograms. Altered flow dynamics cause suboptimal perfusion and distention, complicating precise measurements and challenging stent planning-especially when the tumor encroaches near or beyond the SAJ.</p><p><strong>Methods: </strong>We integrated intravascular ultrasound (IVUS) into our procedural workflow and evaluated its utility in a series of 27 cases involving malignancy-related SVCO between November 2023 and March 2025. We measured the distance from the midpoint of the stenosis to the SAJ (stenosis-to-SAJ distance) and identified cases requiring IVUS for accurate assessment of the caudal landing zone.</p><p><strong>Results: </strong>Parametric testing revealed a stronger correlation between stenosis-to-SAJ distance measurements on IVUS and computed tomography (CT) than between digital subtraction angiography and CT. Statistical analysis determined that a stenosis-to-SAJ distance of ≤ 40 mm was significantly associated with the need for IVUS (<i>P</i> = 0.008), whereas the association at ≤ 50 mm was not statistically significant (<i>P</i> = 0.069).</p><p><strong>Conclusion: </strong>Stenting becomes particularly challenging when tumors invade the SAJ. Our findings suggest that IVUS provides valuable visualization and measurement, particularly in cases with a stenosis-to-SAJ distance of ≤ 40 mm, making it a useful adjunct for safe and effective SVC stent placement.</p><p><strong>Clinical significance: </strong>Visualization of venous anatomy and the exact extent of SVC stenosis is difficult in cases of severe obstruction, especially when the tumor encroaches upon the SAJ, making stent selection and deployment challenging. The use of IVUS facilitates visualization of the precise extent of the stenosis and delineates the location of the SAJ. A stenosis-to-SAJ distance of ≤ 40 mm significantly benefits from the concomitant use of IVUS for accurate stent placement.</p>","PeriodicalId":11341,"journal":{"name":"Diagnostic and interventional radiology","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147833762","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}

Two analytic datasets were constructed: Dataset 1 compared patients with ankle sprains and MRI-confirmed ligament tears to healthy controls with completely normal ankle MRIs; Dataset 2 compared controls, patients with sprains but no ligament tears, and patients with sprains and ligament tears. Standardized morphometric measurements of the distal tibiofibular syndesmosis and talocrural joint were obtained, including absolute and ratio-based parameters. Group comparisons were performed using appropriate univariable tests with multiple-comparison correction. Multivariable logistic regression was used to identify independent predictors of ligament tears.

Multivariable analysis demonstrated that tibiofibular clear space and the fibular notch depth-to-tibial thickness ratio were independent predictors. In Dataset 2, tibiofibular clear space, fibular notch depth-to-tibial thickness ratio, and lateral malleolar height-to-talar articular width ratio differed significantly across three groups (all <i>P</i> < 0.05). Notably, only the lateral malleolar height-to-talar articular width ratio independently differentiated patients with sprains and ligament tears from those without tears (<i>P</i> = 0.025).
