Endovascular repair of renal artery anastomotic pseudoaneurysm following thoracoabdominal graft replacement

Anastomotic pseudoaneurysm following thoracoabdominal graft replacement is a rare but potentially life-threatening complication. Although surgical repair remains the definitive treatment, it is often significantly more invasive than the initial procedure owing to extensive tissue adhesion. Patients with severe frailty are generally not considered suitable candidates for such highly invasive interventions. We present a successful case of endovascular repair of a right renal artery anastomotic pseudoaneurysm using a small-diameter stent graft and coils in an elderly patient with high-grade frailty.
