Repairing abdominal aortic aneurysms in patients with horseshoe kidneys presents challenges. A left retroperitoneal approach proved successful for abdominal aortic aneurysm repair in a woman with this complex anatomy.
Area of Science:
- Vascular Surgery
- Anatomical Variations
Background:
- Abdominal aortic aneurysm (AAA) repair in the presence of renal anomalies, such as horseshoe kidney, poses unique surgical challenges.
- The optimal surgical strategy for AAA in patients with horseshoe kidney remains debated, requiring careful consideration of anatomical complexities.
Observation:
- A 77-year-old female patient presented with an abdominal aortic aneurysm and a horseshoe kidney.
- The horseshoe kidney presented a complex anatomical variation that needed to be addressed during AAA repair.
Findings:
- Successful repair of the abdominal aortic aneurysm was achieved using a left retroperitoneal approach.
- This surgical approach facilitated safe and effective management of the AAA despite the presence of the horseshoe kidney.
Implications:
- The left retroperitoneal approach may be a viable option for managing abdominal aortic aneurysms in patients with horseshoe kidneys.
- This case highlights the importance of tailored surgical strategies for complex vascular pathologies involving anatomical variations.
