Diagnosis and therapy for primary hepatic carcinoma: transcatheter inferior phrenic arteriography and chemoembolization.

Transcatheter inferior phrenic arterial (IPA) and hepatic arteriography was performed on 38 patients with advanced primary hepatic carcinoma (PHC) with blood supplied by IPA and hepatic artery. 18 patients received single treatment with hepatic arterial infusion (HAI) or embolization (HAE) 20 received double treatment with IPA and hepatic arterial infusion or embolization. The results show that the double treatment is superior to the single one. The angiographic features and mechanism of parasitization of inferior phrenic arterial supply to PHC were also discussed.
