Abstract:
Objective To report the preliminary results of placing metallic stent and ~(125)Ⅰ seed strand combined with transcatheter arterial chemoembolization (TACE) for the treatment of hepatocellular carcinoma (HCC) with inferior vena cava (IVC) obstruction. Methods From March 2009 to June 2009, implantation of radioactive ~(125)Ⅰ seed strand and metallic stent combined with TACE treatment was performed in 8 cases of HCC with malignant IVC obstruction. All patients were males with a mean age of (60.6 ± 9.6) years, ~(125)Ⅰ seed strand and Z-type soft-expandable metallic stent were placed in the obstructive segment of IVC, which was followed by TACE. Before and after the treatment, the diameter of the obstructive segment of IVC, the pressure gradient between right atrium and distal end of obstructive segment of IVC, and the symptoms related to the obstruction were estimated and recorded, the results were compared individually. Clinical follow-up was conducted in all patients. Results A total of 8 stents and 10 ~(125)Ⅰ seed strands were placed in the obstructive segment of IVC. Altogether 138 ~(125)Ⅰ seeds were implanted in 8 patients. Obvious clinical improvements were obtained after therapy. No complications occurred in all patients except one patient who experienced acute renal dysfunction at the second day after therapy. During a mean of (2.1 ± 0.6) months follow-up, occlusion of IVC stent was detected in 1 patient. The remaining stents remained patent. Conclusion Our initial results indicate that placement of ~(125)Ⅰ seed strand and metallic stent combined with TACE is a safe and feasible therapeutic option for advanced HCC with malignant IVC obstruction.
