Health Related Quality of Life Following Intervention for Thoracoabdominal Aortic Aneurysm: A Systematic Review and Narrative Synthesis

BACKGROUND: Thoracoabdominal aortic aneurysms (TAAA) pose significant risks of morbidity and mortality. Considering the evolving techniques for TAAA intervention and the growing interest in quality of life (QoL) outcomes for decision-making, we aimed to evaluate the impact of patient and perioperative characteristics on short-term, medium-term, and long-term postoperative QoL in TAAA repair patients. METHODS: A systematic search was conducted in CINAHL, APA PsycINFO, EMBASE, Medline and Cochrane to identify primary research studies evaluating QoL post TAAA surgery, published in English or Swedish between January 01, 2012 and September 26, 2022. A narrative synthesis was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. The quality of evidence was assessed using the Critical Appraisal Skills Program and Joanna Briggs Institute checklists. RESULTS: Eight studies of low or moderate quality with 455 patients were included. Preoperative QoL in TAAA patients was lower compared to the general population. While there is an initial short-term improvement in postoperative QoL, patients fail to reach baseline levels even after 7 years, with physical activity and functioning domains being particularly affected. Experiencing postoperative complications, including paraplegia and cardiovascular events, negatively impacts postoperative QoL. Patients with uncomplicated postoperative status had improved QoL. Prolonged hospital stay negatively affects physical functioning. CONCLUSIONS: Individuals with TAAA are likely to have lower baseline QoL compared to the general population. Following TAAA repair, postoperative QoL may remain lower than baseline levels, persisting over the long-term. Comorbidities, postoperative complications, and hospitalization duration appear to exert adverse effects on postoperative QoL.
