AI Article Synopsis

  • The article reviews the latest literature on the endovascular treatment of complex abdominal aortic aneurysms (AAAs) using the chimney technique.
  • It highlights concerns regarding target vessel angulation, particularly how it affects the effectiveness of treatment.
  • The findings suggest that while balloon-expandable covered stents work well for downward-oriented vessels, other techniques may be more suitable for transverse and upward-oriented vessels, indicating a need for careful planning and further research.

Article Abstract

This article summarizes the key findings in literature up to date on the endovascular treatment of complex abdominal aortic aneurysms (AAAs) employing the chimney technique. Additionally, an unexplored pitfall is described regarding the target vessel angulation. Although balloon-expandable covered stents present more favorable configuration in downward-oriented target vessels, transverse and upward-oriented target vessels may benefit from other endovascular techniques imploring careful case planning and further investigation on the topic.
