In situ open repair of renal artery aneurysm in 43-year-old with solitary kidney: a case report

Abstract

Abstract Renal artery aneurysms are rare. Indications for management include size > 3 cm, female gender within childbearing age, pain, hematuria, medically refractory hypertension, thromboembolism, dissection, and rupture. Management options include endovascular, open repair, and ex vivo approaches. A 43-year-old female with a history of polycystic kidney disease, solitary kidney, and uncontrolled hypertension was found to have a proximal large renal aneurysm on imaging. The patient underwent an in situ open aneurysm resection, temporary shunt insertion, and patch repair with good postoperative outcomes. Whereas previous studies showed the success of ex vivo repair and autotransplantation in large aneurysms with solitary kidneys, our case demonstrated that in situ open repair and patch with the use of a temporary shunt is a feasible and effective option. In a patient with a solitary kidney and large proximal renal artery aneurysm, an in situ open approach and patch repair with shunt insertion should be considered.
