Patient-Reported Quality of Life After Open Surgery for Complex Abdominal Aortic Aneurysms: A Prospective 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.

Studie Bevolking
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:
- Preoperative baseline (prior to surgery)
- At hospital discharge (within 7 days after surgery)
- 1 month postoperatively
- 6 months postoperatively
- 12 months postoperatively 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.
Beschrijving
Inclusion Criteria:
- 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
Exclusion Criteria:
- 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.

QoL trajectory differences between subgroups
Tijdsspanne: 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.

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
