Surgical treatment of abdominal aortic aneurysm associated with horseshoe kidney and coagulopathy case report.

The coexistence of horseshoe kidney and aortic aneurysm poses a technical challenge to the vascular surgeon during aneurysm repair. Whether to divide the renal isthmus and how to approach the aneurysm are still matters ofcontroversy, and coagulopathy sometimes occurs in patients with nontreated abdominal aortic aneurysm (AAA). We describe the successful surgical repair of an AAA with horseshoe kidney via the transperitoneal approach and division of the renal isthmus by harmonic scalpel. Exclusion of a thrombosed aneurysm can ameliorate coagulopathy due to AAA.
