Introduction:
The association of aortic aneurysm with congenital pelvic kidney is an uncommon condition and has been described in association with abdominal aortic aneurysm (AAA) open repairs.
Report:
We present a case of a patient with a type IV thoraco-abdominal aortic aneurysm (TAAA) extending into the left common and internal iliac arteries associated with a congenital pelvic kidney who was treated with a customised endovascular prosthesis involving proximal fenestrations, bifurcation fenestration and a left internal deep iliac branch device.
Discussion:
Although branch technology continues to evolve, cases such as this are encouraging for future widespread use. This approach allowed us to offer TAAA repair without compromising renal function in a patient with multiple co-morbidities who probably would not have withstood conventional open treatment.
