Evaluating outcomes of thoracic aortic repair in patients with compromised landing zones

Thoracic Endovascular Aortic Repair in Compromised Distal Landing Zones

Observational Fondazione Policlinico Universitario Agostino Gemelli IRCCS · NCT06882967

This study is testing different stent-graft options for patients with aortic aneurysms who have tricky anatomy to see if they can prevent complications after surgery.

What this trial studies

This observational study focuses on patients undergoing thoracic endovascular aortic repair (TEVAR) for descending thoracic aortic aneurysms, particularly those with compromised distal landing zones (CDLZs). It aims to assess the effectiveness of various stent-graft interventions, including distal active fixation stent-grafts and Aptus Heli-FX EndoAnchors, in preventing complications such as stent graft migration and endoleaks. The study will evaluate outcomes based on specific morphological features of the aorta that may affect the success of the repair. By analyzing these outcomes, the study seeks to improve the management of patients with challenging aortic anatomies.

Who should consider this trial

Good fit: Ideal candidates include patients with descending thoracic aortic aneurysms greater than 55mm in diameter or those experiencing rapid growth, along with specific adverse morphological features.

Not a fit: Patients in emergency settings or those with aortic dissection pathology may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved outcomes and reduced complications for patients undergoing TEVAR.

How similar studies have performed: While there is limited data on the specific interventions being tested, the focus on compromised landing zones in TEVAR is gaining attention, suggesting potential for meaningful advancements.

Eligibility criteria
