Evaluation of 3D Overlay During Transjugular Intrahepatic Portosystemic Shunt (TIPS) Procedure
NCT02053571 · View on ClinicalTrials.gov ↗
Study Summary
The goal of this study is to evaluate an alternate approach, which involves using a 3D puncture path overlay, to access the portal vein during a Transjugular Intrahepatic Portosystemic Shunt (TIPS) procedure. The study should determine if the alternate approach provides these benefits: improved safety of procedure, and reduced intervention time (including reduction of radiation exposure), which benefits both interventional radiologist and the patient. During a TIPS procedure, a shunt or stent (mesh tube) is passed down the jugular vein (the vein above the collarbone in the neck) using fluoroscopy (x-ray) guidance. The shunt then is inserted between the portal vein (vein that carries blood from the digestive organs into the liver) to a hepatic vein (vein that carries blood away from the liver back to the heart). In the standard approach, the interventional radiologist uses two-dimensional guidance (2D - having the dimensions of height and width only) to locate the path between the portal vein and hepatic vein. However, since these two veins do not connect, this method does not provide information on the three-dimensional (3D) relationship between the two veins. In the alternate approach, the physician will have the option of using 3D guidance to locate the path. An on-table limited (small field of view) CT scan, used in combination with FDA approved imaging software, will provide a 3D image demonstrating the relationship between the portal vein and the hepatic vein. The 3D image is overlaid on the standard live x-ray images to assist in needle guidance during the TIPS procedure. The CT scan performed will be in place of the angiograms that are typically performed. However, if the portal vein is not adequately seen in the CT images, the angiograms will be done and there will be no overlay. The procedure will proceed using the standard approach.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT02053571
The ClinicalTrials.gov registry entry for NCT02053571 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 20 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Medical College of Wisconsin, which has 614 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Portal Hypertension appearing as the primary indexed condition, and to 1 intervention — of which TIPS with 3D Overlay is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT02053571 reports 1 study location spanning 1 distinct geographic area — top geographies include Wisconsin. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
