Hepatic arterial occlusion (HAO) is frequently encountered in patients receiving hepatic arterial infusion chemotherapy (HAIC) via an implanted port-catheter system. Usually, HAO precludes continuation of HAIC, and treatment for liver metastases is changed to systemic chemotherapy. However, two cases were encountered in which, even though HAO was diagnosed by arteriography via the port, the hepatic artery was actually patent. These cases illustrate that arteriography via the port is insufficient to confirm HAO.
肝动脉闭塞（HAO）在通过植入式端口导管系统接受肝动脉灌注化疗（HAIC）的患者中经常出现。通常，HAO会妨碍HAIC的继续进行，肝转移瘤的治疗会改为全身化疗。然而，遇到了两例病例，尽管通过端口进行血管造影诊断为HAO，但肝动脉实际上是通畅的。这些病例表明，通过端口进行血管造影不足以确诊HAO。
