An observational study in Abdominal Aortic Aneurysm, Infrarenal Abdominal Aortic Aneurysm and Penetrating Aortic Ulcers (PAUs), sponsored by University of Bologna. Not yet recruiting. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-02-24.
Sponsored by University of Bologna · Observational
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.
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:

The study population consists of adult patients diagnosed with infrarenal Abdominal Aortic Aneurysm (AAA) or Penetrating Aortic Ulcer (PAU) referred to the Vascular Surgery Unit of Policlinico Sant'Orsola (a tertiary academic medical center). Participants are selected from the standard waiting list for elective repair based on anatomical suitability for a percutaneous approach (Green/Yellow patterns) and social eligibility for the fast-track early discharge protocol.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Patients 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).
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
Time frame: Intra-operative
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
Time frame: 30 days
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.
Time frame: From hospital admission to discharge, assessed up to 30 days. Unit of Measure: Days
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
Time frame: Time Frame: Intra-operative up to Post-Operative Day 1
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
Time frame: 30 days
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
Time frame: 1 year

Start is estimated for Feb 2026; primary completion for Dec 2026, 10 months later.
Of 67 non-industry observational studies under Aortic Aneurysm, Abdominal, half reached primary completion within 48 months of starting (the median), counting those still running; a quarter within 22 and three quarters within 83. This study's planned 10 months is below that.
Counting every sponsor, half of 91 studies reached it within 48 months; a quarter within 24 and three quarters within 83.
