Left flank retroperitoneal exposure: a technical aid to complex aortic reconstruction.

Area of Science:

• Vascular Surgery
• Surgical Approaches

Background:

• Complex aortic reconstructions present significant surgical challenges.
• The retroperitoneal approach offers an alternative to transabdominal methods.

Purpose of the Study:

• To evaluate the utility and outcomes of an extended left flank retroperitoneal approach for technically complex aortic reconstructions.
• To identify specific indications and assess the safety and efficacy of this surgical technique.

Main Methods:

• Retrospective analysis of 85 aortic reconstructions using an extended left flank retroperitoneal approach over 5 years.
• Detailed review of patient demographics, indications, operative details, and postoperative outcomes.

Main Results:

• The approach was used in 16% of complex aortic reconstructions, primarily for abdominal aortic aneurysm repair (82%).
• Indications included "hostile" abdomen, juxta/suprarenal aneurysms, large aneurysms, and obesity.
• Suprarenal/supraceliac clamping was needed in 50% of cases.
• Average length of stay was 10.2 days with minimal morbidity and a 1.2% perioperative mortality rate for elective cases.

Conclusions:

• The extended left flank retroperitoneal approach provides excellent proximal aortic exposure and facilitates anastomosis in complex cases.
• This technique is particularly advantageous for large pararenal aneurysms and situations where a transabdominal approach is unfavorable.
• The approach is safe and effective for challenging aortic reconstructions, leading to favorable patient outcomes.
