Inferior Phrenic Artery Embolization in the Treatment of Hepatic Neoplasms

Twenty-nine inferior phrenic artery embolizations were performed in 20 patients with primary or metastatic hepatic neoplasms. All patients had interruption of their hepatic arteries by previous infusion of chemotherapy, hepatic arterial embolization or surgical ligation. In one patient, bilateral pleural effusions developed following embolization of the inferior phrenic artery. No other severe complications occurred. Inferior phrenic artery embolization is a safe procedure and permits the continuation of transcatheter treatment of hepatic neoplasms.
