  • Adult, Older adult

Study population: a sample of 320 subjects will be analyzed (considering the cases treated in the period: October 2015 - 31 december 2019).

An informatic database will be set up for the exclusive use of investigators. The data will be analyzed subsequently through the application of descriptive and inferential statistics techniques.

Who may be able to join

  • adult patients aged ≥ 18 years, belonging to the Operative Unit of Vascular Surgery of the San Raffaele Hospital,
  • patients candidates for endovascular treatment for thoracic, thoracoabdominal or abdominal aortic pathologies.

About this study

Purpose of the study is the evaluation of the applicability of the percutaneous technique through double Proglide and Pre-Close Technique to the treatment of complex aortic aneurysms with thoracic endoprosthesis (TEVAR), fenestrated or branched (F / B-EVAR) in which patient-related factors, the devices used or the procedure, could affect the performance.

Read the detailed description

Endovascular treatment using a percutaneous technique (Percutaneous Endovascular Aneurism Repair - P-EVAR) has been used with increasing frequency to treat aortic aneurysms by reducing operative times, postoperative pain and length of stay, compared to treatment by surgical femoral access. During EVAR procedures, two accesses to the femoral arteries are required to introduce the necessary tools for the stentgraft implantation. Such accesses can be classically obtained by surgical incision, isolation of the common femoral arteries and direct introduction of the devices.

Alternatively, the most modern approach involves direct puncture of the artery (without the need for incision), through the skin and closure of the arterial breach through prolonged manual compression of the vascular closure or systems (Vascular Closure Devices - VCD) specifically designed. Among the various closure devices one of the most used and studied is the Perclose Proglide (Abbott Vascular, Santa Clara CA, USA) that allows to affix a polypropylene stitch to close the arterial breach. When closing high-caliber accesses (> 8 French) it is necessary to use two devices that must be positioned before inserting the introducer ("Pre-Close Technique").

Few studies have so far evaluated the application of this method to the treatment of complex cases such as thoracic or thoracoabdominal aortic aneurysms that requiring the use of high caliber introducers.

This is a retrospective observational study (320 cases treated in San Raffaele hospital in Milan, during the period: October 2015 - 31 December 2019).

The chronology of the assessments will include:

  • An immediate evaluation at the end of the procedure by performing the ecocolordoppler examination of the percutaneous accesses performed (as per routine). On the basis of longitudinal and sagittal scans of the vessel, the Physician must check the presence of the above complications that could be considered as "failure" of percutaneous access. In the event that these complications are clinically evident (eg uncontrollable bleeding from the puncture site), in the interest of a prompt management of the surgical problem, it will not be necessary to perform an ecocolordoppler examination and the outcome will be assigned "failure ".
  • A second echocolordoppler assessment performed on the first postoperative day (as per routine) The study will be conducted in accordance with the ethical principles deriving from the Helsinki Declaration and the current legislation on Observational Studies.

What is being measured

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

  1. technical success

    Use of femoral artery access in endovascular repair of aortic aneurysm (time frame between 2015 and 2020)

    • Endovascular procedure: TEVAR - EVAR - B/FEVAR
    • Side of femoral access: right- left
    • Employment of downsizing on the femoral access: yes - no, as reported on patients' charts and operative report
    • Size of percutaneous access sheath employed measured in French - Fr
    • Number of percutaneous access vessel closure devices employed
    • Access closure specific outcome: success - failure, as reported on patients' charts and operative report
    • Cause of failure: hemorrhagic - occlusive, as reported on patients' charts and operative report

    Measured: during the surgery

Secondary outcomes (1)
  1. minor complications

    Femoral access vascular anatomy and patient's characteristics (time frame between 2015 and 2020):

    • Previous surgical access to ipsilateral femoral artery: yes - no
    • Previous deployment of percutaneous vascular closure devices to ipsilateral femoral artery: yes - no
    • Diameter of femoral artery measured in millimiters (mm)
    • Presence of calcification at access site: less or equal to1/3 of circumference - between 1/3 (excluded) and 2/3 (included) - more than 2/3 as measured on preoperative CT scan
    • Localization of calcification: anterior - posterior - circumferential - lateral
    • Body mass index reported as bare number defined as weight (kg)/height^2(m^2)

    Measured: 30 days after surgery

Questions about this trial

What is this clinical trial studying?

An observational study of Aneurysm and Aneurysm Abdominal, run by IRCCS San Raffaele at 1 site in Italy.

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 14 May 2020. 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?

technical success (time frame: during the surgery). 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 NCT03484013, which also lists 1 linked publication.

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 14 May 2020.
