Analysis of the origin of the right inferior phrenic artery in 178 patients with hepatocellular carcinoma treated by chemoembolization via the right inferior phrenic artery

Abstract

In our study, the RIPA originated from the aorta between the CA and the SMA directly in 17% of cases. When it is difficult to identify the origin of the RIPA, we must keep in mind that the RIPA may originate from the right part of the aorta within the small distance between the SMA and the CA.
