Description

In terms of prognosis, the evaluation and treatment of arterial disease using iodinated contrast medium is restricted in patients with renal dysfunction or drug allergies. Cases of endovascular therapy (EVT) using carbon dioxide (CO2) angiography have recently been reported. We admitted a 75-year-old man presenting with renal dysfunction and a complaint of left foot pain. Carbon dioxide angiography revealed severe stenosis in both the common iliac and left anterior tibial arteries. We diagnosed arteriosclerosis obliterans (ASO) and performed percutaneous arterial ballooning and stenting. By utilizing CO2 angiography and intravascular ultrasound (IVUS), we successfully treated EVT in a patient with renal insufficiency involving below-knee arterial stenosis.
