Clinicopathologic Study of Magnetic Microsphere Embolization for Tumor / 实用放射学杂志

ABSTRACT

Objective To investigate pathologic changes and method of magnetic microsphere(Fe3O4) embolization for tumor.Methods 18 cases with tumors were treated by embolized using Fe3O4 under fluoroscopy through catheters by Seldinger’s technique,pathological examinations were done in 15 cases before operation,including primary hepatic carcinoma in 8,renal carcinoma in 6,renal myolipoma in 3 and breast carcinoma in 1.Results Pathological examination after embolism showed that necrosis of neoplastic tissue was 100 percent.Conclusion Fe4O4 is a good embolic substance for treating tumors and there is no damage to the other tissues.
