Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Participants will be enrolled by the Department of Vascular Surgery in three different centres. Patients will be included if there is a diagnosis of complex abdominal aortic aneurysms (cAAAs), defined as juxtarenal, pararenal and suprarenal/paravisceral aneurysms. The study includes five time points for data collection: 1. Preoperative baseline (prior to surgery) 2. At hospital discharge (within 7 days after surgery) 3. 1 month postoperatively (± 1 weeks) 4. 6 months postoperatively (± 2 weeks) 5. 12 months postoperatively (± 4 weeks) At each of these time points, participants will complete the Short Form-36 (SF-36) Health Survey questionnaire to assess HRQOL, including physical and mental well-being.

Who may be able to join

  • Patients over 18 years old
  • Patients undergoing open surgical repair for complex abdominal aortic aneurysms (AAAs), including juxtarenal, pararenal and suprarenal/paravisceral aneurysms
  • Patients treated for asymptomatic or symptomatic non ruptured aneurysms
  • Patients who are able and willing to provide informed, complete, and accurate responses to the SF-36 questionnaire

Who cannot join

  • Patients under 18 years old
  • Patients treated for ruptured abdominal aortic aneurysms
  • Patients with incomplete data, or who denied consent
  • Patients with cognitive impairment or other conditions that prevent them from reliably completing the SF-36 questionnaires.

About this study

STUDY DURATION: January 2026 - December 2027 Each participant will be followed for 12 months postoperatively.

BACKGROUND AND RATIONALE: Complex abdominal aortic aneurysms (cAAAs)-including juxtarenal, pararenal, and suprarenal aneurysms-can be treated via open surgical repair (OSR) or complex endovascular techniques (f/bEVAR). While OSR may offer better long-term durability, especially in fit patients, there is currently a lack of data on patient-reported quality of life (QoL) outcomes following OSR for cAAAs. This study aims to fill this gap and support shared decision-making in vascular surgery.

OBJECTIVES:

  • Primary Objective: To assess changes in health-related quality of life (HRQoL) using the Short Form-36 (SF-36) questionnaire at five predefined time points (baseline, discharge, 1 month, 6 months, and 12 months post-surgery).
  • Secondary Objectives: To analyze QoL differences by patient subgroups (e.g., age, comorbidities, aneurysm type), to assess correlations with clinical outcomes (e.g., complications, hospital stay), and to evaluate the impact of postoperative complications on QoL.

STUDY POPULATION:

  • Inclusion criteria: Adults (≥18 years) undergoing OSR for non-ruptured complex AAAs (juxtarenal, pararenal, suprarenal).
  • Exclusion criteria: Patients under 18, those with ruptured AAAs, cognitive impairment, or those unable to complete the SF-36 questionnaire.

PARTICIPATING CENTERS:

  • Ospedale Regionale di Lugano (EOC), Switzerland
  • Luzerner Kantonsspital, Switzerland
  • Centre Hospitalier Universitaire de Montpellier, France

STUDY PROCEDURES:

  • Administration of the SF-36 questionnaire at five time points: preoperative, at discharge (within 7 days), and at 1, 6, and 12 months postoperatively.
  • Data collection includes demographic information, aneurysm characteristics, in-hospital and follow-up outcomes, and questionnaire responses.

What is being measured

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

  1. Change in health-related Quality of Life

    The primary end point will be the analysis of change in health-related Quality of Life as measured by the SF-36 score between 5 time points.

    Measured: preoperative (baseline), hospital discharge (within 1 week after surgery), 1 month after the procedure (± 1 weeks), 6 months after the procedure (± 2 weeks) and 1 year after the procedure (± 4 weeks).

Secondary outcomes (1)
  1. QoL trajectory differences between subgroups

    Secondary outcomes will include quality of life (QoL) trajectory differences between subgroups (e.g., age groups, comorbidity burden, aneurysm complexity), correlation between QoL outcomes and clinical variables (e.g., length of hospital stay, Intensive Care Unit (ICU) duration, postoperative complications), and incidence of postoperative complications and their impact on QoL

    Measured: preoperative (baseline), hospital discharge (within 1 week after surgery), 1 month after the procedure, 6 months after the procedure and 1 year after the procedure.

Questions about this trial

What is this clinical trial studying?

An observational study of Complex Abdominal Aortic Aneurysms, run by Prouse Giorgio at 2 sites in Switzerland.

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 4 inclusion and 4 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: looking for participants now, as of the sponsor's last update on 28 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Switzerland. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Giorgio Prouse, MD (+410918116328, giorgio.prouse@eoc.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in health-related Quality of Life (time frame: preoperative (baseline), hospital discharge (within 1 week after surgery), 1 month after the procedure (± 1 weeks), 6 months after the procedure (± 2 weeks) and 1 year after the procedure (± 4 weeks).). 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 28 Sep 2026; AzTrials last refreshed its copy on 6 Nov 2026.
