Customised stent graft for complex thoraco-abdominal aneurysm associated with congenital pelvic kidney.

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.
