Area of Science:

• Vascular Surgery
• Endovascular Interventions
• Aortic Aneurysm Treatment

Context:

• Juxtarenal abdominal aortic aneurysms (JAAs) pose significant surgical challenges due to their proximity to visceral arteries.
• Conventional open repair is associated with high morbidity and mortality, especially in patients with multiple comorbidities.
• Advancements in endovascular techniques, including fenestrated stent grafts, provide alternative treatment options.

Purpose:

• To report the initial clinical experience with custom-made fenestrated stent grafts for treating complex juxtarenal abdominal aortic aneurysms.
• To evaluate the technical success, early complications, and mid-term outcomes of this endovascular approach.
• To highlight the feasibility of treating JAAs with visceral involvement using fenestrated endovascular repair.

Summary:

• Two patients with complex juxtarenal abdominal aortic aneurysms underwent successful endovascular repair using custom-made fenestrated stent grafts.
• The first patient experienced a temporary left renal stent occlusion requiring reintervention, while the second patient had patent fenestrations at one month.
• The study demonstrates the potential of fenestrated endovascular repair for JAAs, with short- and mid-term results comparing favorably to open surgery.

Impact:

• Fenestrated endovascular repair represents a significant advancement in treating complex aortic aneurysms, potentially reducing surgical risks.
• This technology enables complete endovascular solutions for juxtarenal aneurysms involving visceral arteries.
• Further long-term studies are needed to fully ascertain the durability and benefits of fenestrated endograft technology compared to traditional surgical methods.
