| After accessing the right femoral artery with a micropuncture needle under ultrasound guidance, a thoracic aortogram was performed using a 5Fr pigtail catheter. |
| Preoperative aortogram may confirm the diagnosis and identify the vascular supply, in order to avoid catastrophic intraoperative bleeding. |
| Subsequently, he underwent a digital subtraction aortogram and bilateral selective renal arteriography. |
| An abdominal aortogram confirmed high-grade stenosis of both iliac arteries. |
| An aortogram shows opacification of pulmonary arteries, veins and right atrium as well as the aorta. |
| Pre-operative embolization of the tumour was attempted, however, no tumour enhancement was demonstrated during the aortogram, and embolization was therefore not performed. |
