Clinical Analysis of Embolizing Tumor Using Magnetic Microsphere Through Artery Catheter / 实用放射学杂志

ABSTRACT

Objective To investigate the mechanism and the clinical value of magnetic microsphere(Fe_3O_4) in embolizing tumor through artery catheter.Methods 94 patients with tumor were treated by embolized using Fe_3O_4 under fluoroscopy through catheters by Seldinger's technique.Of them,5 cases of hepatocellular carcinoma underwent magnetic field putting on outside the target area,pathological examination was done in 15 cases,25 cases underwent DSA examination one month later and the DSA images before and after operation were analysed statistically.Results Pathological examination after embolism showed that necrosis of neoplastic tissue was 100 percent.The statistical analysis of DSA images was in P
