Mid-Term Outcomes of the Double-Barrel Technique for Patients Who Are Unfit for Standard Endovascular Aortic Aneurysm Repair

Background: Endovascular aortic aneurysm repair (EVAR) is a commonly used treatment for abdominal aortic aneurysms (AAAs), but anatomical complexities limit its application in certain cases. Objective: This study evaluates the mid-term outcomes, referring to a follow-up period with a mean of 29.9 ± 24.1 months (approximately 1–5 years), of a novel double-barrel technique that employs overlapping tubular stent grafts to address these challenges. Methods: A retrospective analysis was conducted on seven patients treated with this technique from May 2014 to February 2023. Patients had narrow and short proximal necks, inadequate landing zones, or required re-do procedures. Results: The double-barrel technique achieved technical success in 85.7% of cases with zero mortality. Patients had an average hospital stay of 11.9 ± 10.0 days and attended follow-up for a mean of 29.9 ± 24.1 months. Minimal complications and no significant adverse events were reported. Conclusions: These findings suggest that the double-barrel technique is a cost-effective and viable alternative for anatomically complex cases where standard EVAR is unsuitable. While promising mid-term outcomes were observed, further studies with larger cohorts are necessary to confirm its long-term effectiveness and broader applicability.
