Imaging findings of hepatic hemangioendothelioma with arteriovenous shunt and evaluation of interventional therapy

Objective To observe the efficacy of arteriosclerosis embolization in the treatment of hepatic hemangio endothelioma (HHE)and the imaging manifestations of HHE. Methods Eight HHE children admitted to our hospital from Oct 2016 to Jan 2019 were enrolled to evaluate the efficacy of interventional therapy and the differentiation from other liver tumors. Results Eight patients underwent 10 interventional operations. The first embolization materials were gelatin sponge particles (2 000 μm). After the second embolization, microspheres (300-500 μm) were used for embolization materials. After superselective embolization, all 8 patients were weaned from the auxiliary ventilation. There was no hepatic venous development during the arterial phase after re-angiography. Tumor volume decreased or disappeared after chemoembolization. Tumors disappeared completely in 3 patients, shrank significantly in the remaining 5 cases. Conclusion Contrast-enhanced scanning is of great significance in the diagnosis of hepatic vascular endothelial cell tumor. Arteriosclerosis embolization has significant effect on children with hepatic vascular endothelial cell tumor. Key words: Liver neoplasms; Interventional therapy
