About this study

Official title: Fast-Track Protocol for Infrarenal EVAR

The study aims to evaluate the clinical and economic efficacy of a "Fast-Track" protocol for the elective endovascular treatment (EVAR) of infrarenal abdominal aortic aneurysms (AAA). The protocol minimizes invasiveness through the use of local/locoregional anesthesia, a total percutaneous approach, and the avoidance of routine Intensive Care Unit (ICU) admission. The primary goal is to reduce hospital Length of Stay (LOS) to <48 hours and decrease procedural costs, while maintaining safety and increasing patient turnover compared to the standard of care.

Read the detailed description

Endovascular Aneurysm Repair (EVAR) is the guideline-recommended treatment for AAA. Despite its minimally invasive nature, standard pathways often involve general anesthesia (80% of historical cases at the institution) and ICU monitoring. The Vascular Surgery Unit at Policlinico Sant'Orsola proposes a structured Fast-Track protocol involving:

  1. Strict Patient Selection: Based on anatomical suitability ("Green/Yellow" criteria) and social support availability.
  2. Peri-operative Management: Same-day admission, procedure performed in a Hybrid Operating Room under local/locoregional anesthesia with percutaneous access. Minimization of invasive monitoring (no central venous catheter, no urinary catheter).
  3. Post-operative Care: Early mobilization, oral intake on Day 0, and planned discharge on Post-Operative Day (POD) 1 or 2.
  4. Follow-up: Telemedicine assessment on POD 3, outpatient visit on POD 6, and CT Angiography at 30 days. The study compares outcomes against historical data (Year 2025) to assess reductions in ICU usage, complications, and costs.

Study groups in NCT07431047
Study groupRoleWhat they receive
Fast-Track EVAR CohortPatients with infrarenal Abdominal Aortic Aneurysm (AAA) undergoing elective Endovascular Aneurysm Repair (EVAR) under local or locoregional anesthesia, managed with the multidisciplinary Fast-Track protocol (percutaneous access, early mobilization, and planned discharge within 24-48 hours).

What is being measured

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

  1. Technical Success

    Technical success is defined as a single composite endpoint. A participant is considered to have achieved technical success only if all of the following criteria are met: successful deployment of the endograft with exclusion of the aneurysm, absence of type I/III endoleaks, patent access vessels, and no conversion to open surgery.. Unit of Measure: Percentage of participants

    Measured: Intra-operative

  2. 30-Day Aorta-Related Mortality

    This outcome is reported as a single overall percentage. Aorta-related mortality is defined as death resulting from any of the following causes: directly attributable to the aortic pathology (e.g., rupture, progression of disease) OR complications related to the procedure/device. A participant experiencing death from any of these specific causes is counted only once towards this single aggregate percentage. Unit of Measure: Percentage of participants

    Measured: 30 days

Secondary outcomes (4)
  1. Mean Length of Stay (LOS)

    The duration of the hospital stay, calculated from the date of admission for the procedure to the date of hospital discharge.

    Measured: From hospital admission to discharge, assessed up to 30 days. Unit of Measure: Days

  2. ICU Admission Rate

    The overall rate of admission to the Intensive Care Unit (ICU). This includes both planned and unplanned admissions. It will be reported as a single overall percentage of participants who required an ICU stay. Unit of Measure: Percentage of participants

    Measured: Time Frame: Intra-operative up to Post-Operative Day 1

  3. 30-Day Mortality and Morbidity

    This is defined as a single composite endpoint. It will be reported as the overall percentage of participants who experience at least one of the following events: all-cause mortality OR major adverse events (specifically: re-intervention, conversion to open surgery, or access site complications). A participant experiencing more than one of these events is counted only once towards this single aggregate percentage. Unit of Measure: Percentage of participants

    Measured: 30 days

  4. Patient Turnover Rate

    Description: The percentage increase in the total annual volume of Endovascular Aneurysm Repair (EVAR) cases treated at the study site(s) during the 1-year study period, calculated relative to the baseline year of 2025. This outcome is evaluated at the institutional level and will be reported as a single overall percentage. Unit of Measure: Percentage

    Measured: 1 year

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: Intra-operative). 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?

On the ClinicalTrials.gov record for NCT07431047, which also lists 6 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 24 Feb 2026.
