Trial summary

The incidence of isolated common iliac artery (CIA) aneurysms is low, but in combination with an abdominal aortic aneurysm (AAA) they are found in approximately 20-40% of cases. Basically, two different endovascular strategies can be applied to treat a CIA aneurysm with, including 1. the coverage and 2. Read more about this study

About this study

Official title: Anatomic Dynamics of the Internal Iliac Artery After Placement of Iliac Branched Devices Using ECG-gated Computer Tomography Angiography Imaging (IBD-dynamics)

The incidence of isolated common iliac artery (CIA) aneurysms is low, but in combination with an abdominal aortic aneurysm (AAA) they are found in approximately 20-40% of cases. Basically, two different endovascular strategies can be applied to treat a CIA aneurysm with, including 1. the coverage and 2. the preservation of blood flow to the internal iliac artery (IIA). Coil and coverage of the IIA is related to ischemic complications, including buttock claudication, erectile dysfunction and the more severe spinal and colonic ischemia. Iliac branched devices (IBD) have been developed to exclude CIA aneurysms preserving the IIA and currently three alternatives are on the market. Clinical results of these devices are promising but loss of patency is not uncommon. The major difference between the two devices is the IIA component. The Cook IBD uses a -non-dedicated IIA component, while in the GORE® EXCLUDER® Iliac Branch Endoprosthesis (Gore IBE device) a dedicated self expanding stent is used. Stresses and forces exerted onto the endograft by aortic pulsatility may have an effect on the durability and functioning of the endograft. Intermittent hinchpoints could also have an effect on stent integrity and stenosis. By evaluating endograft movement during the cardiac cycle (ECG-gated CTA) it is possible to assess the stress and force exerted onto the endograft. This might help gain insight into mechanisms underlying potential endograft failure, and aid procedural planning and the development of future devices with long-term durability.

The choice for device is not part of this study.

Read the detailed description

Objectives:To compare the mobility of the hypogastic artery during the cardiac cycle before and six weeks after implantation of the Gore IBE device in conjunction with its dedicated self expandable Internal Iliac component (Sub-study A);and to quantitatively characterize the displacement of stents with regard to the main body and native IIA during the cardiac cycle on an implanted iliac branched endograft in conjunction with a non-dedicated IIA component (Cook IBD with Advanta V12 or Fluency) with those in conjunction with a dedicated self expandable Internal Iliac component (Gore IBE device). (Sub-study B) Study design: Sub-study A \& B: Multicenter observational case studies Study population: Sub-study A: 15 prospectively included patients and sub-study B: 15 patients in each group that have been treated in the period October 2006 - July 2016.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ECG gated CTARadiation

    Routine care consists of a preoperative and several postoperative CTA scans. In A. The preoperative and first postoperative CTA will be replaced by ECG-gated CTA imaging and in B. the scheduled imaging will be replaced by an ECG-gated CTA.

    General information: The protocol is based on the ECG gated cardiac protocol using abdominal parameter settings.

Study groupRoleWhat they receive
ECG gated CTA pre and post operative at Gore IBEOtherTo prospectively enroll 15 patients that are scheduled for endovascular aneurysm repair using the Gore IBE device in conjunction with its dedicated self expanding Internal Iliac component. Each patient will have an ECG gated CTA scan before the operation and 6-8 weeks after operation, in stead of a regular CT scan.

ECG gated CTA post operative at Gore IBE and Cook IBDOtherTo compare 15 patients that have been treated in the period October 2006- July 2016 with the Cook IBD with a non-dedicated IIA component (Advanta-V12 or Fluency) and 15 matched patients treated with Gore IBE device. Each patient will have an ECG gated CTA after the operation, at the first doctor's appointment, in stead of a regular CT scan.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mobility of hypogastric artery during cardiac cycle (sub study A)

    The mobility of the hypogastic artery during the cardiac cycle before and after implantation of the Gore IBE device (Sub-study A). This will be measured at 15 patients by making an ECG gated CTA per and postoperative.

    Measured: Up to 1 year follow-up

  2. Characterize displacement during cardiac cycle (Sub Study B)

    To quantitatively characterize the displacement during the cardiac cycle on an implanted iliac branched endograft in conjunction with a non-dedicated n balloon expandable IIA component (Cook IBD with Advanta V12 or Fluency) with those in conjunction with a dedicated self expandable Internal Iliac cComponent (Gore IBE device). (Sub-study B). This will be measured by 30 patients (15 pt Cook IBD and 15 pt Gore IBE) an ECG gated CTA postoperative.

    Measured: Up to 1 year follow-up

Questions about this trial

What is this clinical trial studying?

A study testing ECG gated CTA in people with Iliac Aneurysm and Angiography, run by Rijnstate Hospital at 3 sites in Netherlands.

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 2 inclusion and 1 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 12 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Netherlands. 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?

Mobility of hypogastric artery during cardiac cycle (sub study A) (time frame: Up to 1 year follow-up). The study lists 2 primary outcomes in all. 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 12 Feb 2021.
