Trial summary

As endovascular procedures become more complex, there is a growing need for 3D image overlay to assist with device guidance and placement. Currently, a 3D image is typically created intra-operatively using 3D rotational angiography (3D-RA) or cone-beam CT (XperCT). Read more about this study

About this study

Official title: 3D Interventional Tools for Endovascular Procedures in the OR

As endovascular procedures become more complex, there is a growing need for 3D image overlay to assist with device guidance and placement. Currently, a 3D image is typically created intra-operatively using 3D rotational angiography (3D-RA) or cone-beam CT (XperCT). This 3D image may then be overlaid on live fluoroscopy to provide 3D guidance information (Dynamic 3D Roadmapping). Philips Healthcare multimodality overlay products allows registration of a pre-acquired MR/CT or 3D rotational image to live fluoroscopy.

Read the detailed description

Endovascular treatment is performed under the guidance of an X-ray angiography system. Fluoroscopy and conventional 2D digital subtraction angiography (DSA) are used to navigate the interventional device (and implant) across the lesion to achieve a correct bridging of the diseased region of the vessel, while excluding the involvement of patent vessels. Drawbacks of these peripheral interventions include the radiation dose, use of contrast, and need for a clinician with excellent wire-handling skills. The use of 2D imaging alone may not be enough to describe the three-dimensional(3D) relationship between interventional devices (and implants) and the complex vascular anatomy, often making positioning, deployment and evaluation suboptimal. In addition, the endovascular approach can lead to complications such as in-stent thrombosis and type II endoleak (in the case of aortic aneurysms) for which 2D imaging along is again sub-optimal for re-intervention planning and guidance.

As endovascular procedures become more complex, there is a growing need for 3D image overlay to assist with device guidance and placement. Currently, a 3D image is typically created intra-operatively using 3D rotational angiography (3D-RA) or cone-beam CT (XperCT). This 3D image may then be overlaid on live fluoroscopy to provide 3D guidance information (Dynamic 3D Roadmapping). 3D navigation can also be acquired by registration of a pre-acquired MR/CT or 3D rotational image to live fluoroscopy.

Questions about this trial

What is this clinical trial studying?

An observational study of Abdominal Aortic Aneurysm (AAA) and Thoracic Aortic Aneurysm (TAA), run by Philips Clinical & Medical Affairs Global at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

feedback to improve the usability of the Vessel Navigator (time frame: one month after procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Dec 2024.
