About this study
Official title: Anatomical Feasibility of an Off-the-shelf Scalloped Stent-graft for Infrarenal Abdominal Aneurysm With a Hostile Neck (ReSTHoNe Study)
In clinical practice a lot of EVAR cases are performed IFU for adverse neck anatomy(6) with acceptable short- and mid-term outcomes, but the long-term durability is currently an issue (7). Neck length shorter than 15 mm and angulation are two of. neck charteristics. that contribute more to define an "hostile neck" (8). The issue linked to the anatomical not feasibility of standard EVAR in patients not eligible for OR can be solved with custom made devices (CMD), but they were limited by high production costs and long time for creations (10-12 weeks)1. Nowadays no one off-the-shelf device aimed to overcome neck hostility in AAA is available on the market.
The present study aims at evaluating the anatomical applicability of an off-the-shelf scalloped stent-graft to treat infrarenal AAA with a short and/or angulated neck.
Read the detailed description
Endovascular aneurysm repair (EVAR) is currently accepted as the preferred choice to treat abdominal aortic aneurysms (AAA) with feasible anatomy. Although approximately 40-60% of AAA patients are not considered anatomically feasible for EVAR, mainly in reason of a "hostile neck anatomy". In ''real-world'' clinical practice, up to 44% of EVAR cases are performed outside Instruction For Use (IFU) for adverse neck anatomy. The off-label use of standard EVAR is currently used for patients who are not eligible for OR, with acceptable short- and mid-term outcomes, Endovascular aneurysm repair (EVAR) is currently accepted as the preferred choice to treat the abdominal aortic aneurysms (AAA) with feasible anatomy. Although approximately 40-60% of AAA patients are not considered anatomically feasible for EVAR, mainly in reason of a "hostile neck anatomy"3-5. In ''real-world'' clinical practice, up to 44% of EVAR cases are performed outside Instruction For Use (IFU) for adverse neck anatomy. The off-label use of standard EVAR is currently used for patients who are not eligible for OR, with acceptable short- and mid-term outcomes, but the long-term durability of EVAR depends on the maintenance of the seal between the endograft and the aortic neck as well as the iliac arteries. Some aortic neck characteristics contribute to the definition of ''hostile neck,'' particularly length shorter than 15 mm and angulation among others. From a recent Consensus Conference, the influence of each characteristic on early or late EVAR failure is not clear, but hostile neck morphology is generally associated with higher rates of aneurysm-related adverse events and mortality. A recent independent Expert Panel, applying the Delphi methodology Indeed, agreed to define 10 mm as the threshold value below which standard EVAR should not be considered feasible. Moreover, the same experts agreed on the fact that an angulation above 60° is considered a hostile criterion for EVAR procedure. Finally should be considered that some "hostility" factors can be present at the same time and create the ideal condition for EVAR failure. The issue linked to the anatomical not the feasibility of standard EVAR in patients not eligible for OR can be solved with custom made devices (CMD), but they were limited by high production costs and long time for creations (10-12 weeks)1. Nowadays no one off-the-shelf device aimed to overcome neck hostility in AAA is available on the market.
The present study aims at evaluating the anatomical applicability of an off-the-shelf scalloped stent graft to treat infrarenal AAA with a short and/or angulated neck. From an informal review of some CTA of patients treated with EVAR or OR in mentioned unit, the authors found that more the 20% presented a distance between the two renal arteries more than 5mm. The idea of an "off-the-shelf" graft with a single scallop theoretically had to permit to gain some length along the aortic neck. Furthermore also in the case of angulation, a single scallop theoretically reduced the risk of bird beck and gutter. The aim of the study is to evaluate if a single scalloped "off-the-shelf" stent graft could be appliable and feasible in an adequate number of patients.

What is being measured
The primary outcome is the main question the study is designed to answer.
Anatomica feasibility and applicability of an "off-the-shelf" scallopped stent-graft measured mesured fitting three device model with data recorded from CTA of patients with AAA treted in our unit
observational study on the anatomical applicability in the coordinator center of an off-the-shelf scalloped device to treat infrarenal AAA with short and/or angulated neck. 3 different endograft designs were constructed. The preoperative measurements were made according to a previously described methodology. The models were matched with each preoperative CTA measure in order to evaluate if they fit or not in the index patients.
Measured: 6-months

Questions about this trial
What is this clinical trial studying?
An observational study of Aortic Aneurysm, run by Azienda Ospedaliero-Universitaria di Modena at 1 site in Italy.
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 5 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 6 Feb 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 Italy. 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?
Anatomica feasibility and applicability of an "off-the-shelf" scallopped stent-graft measured mesured fitting three device model with data recorded from CTA of patients with AAA treted in our unit (time frame: 6-months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05150873, which also lists 10 linked publications.
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 6 Feb 2024.
