【 摘 要 】

An 88-year-old woman with a history of multiple hepatocellular carcinomas (HCCs) presented with a new HCC in segment seven of the liver. We decided to perform transarterial chemoembolization for HCC. During treatment, the HCC was supplied by the right inferior phrenic artery (IPA), which originated from the proximal part of the left gastric artery with a steep bifurcation angle. Due to the very short distance between the origins of the left gastric artery and right IPA, the microguidewire and microcatheter were unstable in the left gastric artery and easily prolapsed into the celiac artery . Although different types of microcatheters were used, the right IPA could not be selected. Therefore, we used a dual-lumen microcatheter (DLM) to select the right IPA. The DLM stabilized the microguidewire in the left gastric artery, and the right IPA was successfully selected. Subsequently, transarterial chemoembolization was administered using a branch of the right IPA. Given this experience, we will consider using a DLM as an alternative method for selecting an abdominal artery when other techniques are unsuccessful.
