Common trunk of the right accessory renal artery and right inferior phrenic artery originating from the thoracic artery: An unreported variation

Accessory renal arteries (ARAs) are common and usually originate from the abdominal aorta and the renal artery. Inferior phrenic arteries (IPAs) can also arise from the abdominal aorta or its branches. In this paper, we present the first case of a common trunk of the right ARA and right IPA arising from the thoracic artery at the level of T10, which was discovered by multidetector-row computed tomography in pretherapeutic evaluation and clearly confirmed by selective angiography. It is important to recognize this anatomical variation when performing cardiovascular and interventional radiological procedures.
