Transperitoneal approach and right retroperitoneal dissection for abdominal aortic aneurysm

Area of Science:

• Vascular Surgery
• Surgical Techniques
• Abdominal Aortic Aneurysm

Background:

• Standard transperitoneal approach is suitable for most abdominal aortic aneurysms.
• Complex cases like large aneurysms, supra-renal extension, renal reconstruction, or prior abdominal surgeries necessitate alternative approaches.

Purpose of the Study:

• To evaluate a combined transperitoneal and retroperitoneal approach for complex abdominal aortic aneurysm resection.
• To assess the efficacy of this technique in providing adequate surgical exposure in challenging patient populations.

Main Methods:

• A midline transperitoneal incision was used to access the abdominal aorta.
• A right retroperitoneal dissection was performed to achieve suprarenal aorta exposure.
• The technique was applied to ten patients with complex abdominal aortic aneurysms.

Main Results:

• The combined approach provided excellent exposure of the suprarenal aorta in all ten patients.
• This technique facilitated the resection of complicated abdominal aortic aneurysms.

Conclusions:

• A combined transperitoneal incision and right retroperitoneal dissection is a valuable technique for complex abdominal aortic aneurysm resection.
• This approach is recommended for patients with large, supra-renal, or previously operated abdominal aortic aneurysms.
