肝癌栓塞后碘油沉积形态与疗效关系的研究

动态观察４５例肝癌经１～３次肝动脉栓塞术后碘油沉积情况并分析与疗效的关系。结果表明，栓塞１个月后碘油沉积量和ＣＴ形态与疗效有明显的相关性。２次栓塞后的碘油ＣＴ表现更能确切反映肿瘤内碘油沉积形态。密实型和环型疗效最好，重复栓塞可使肿癌进一步缩小；集簇型和缺损型疗效次之。２次栓塞非常主要，有望转为密实型提高疗效，但稀少型重复栓塞仍未显治疗效果。碘油沉积量越多疗效越好。碘油沉积量＜３０％者重复栓塞未见明显改观。

Correlation between Lipiodol Deposition Patterns and Therapeutic Effect on Hepatic Cell Carcinoma

orty-five cases of hepatic cell carcinoma(HCC)undergone(once,twice or three times);lipiodoltrans-arterial embolism (LP-TAE)were studied with serial CT scans.The result showed that therewas a close correlation between deposition patterns and amount which was shown on CT, CT after 2ndLP-TAE demonstrated the deposition pattern more exactly. The consol idated and circular patternsdemonstrated the greatest effect of reducing tumor size the 2nd LP-TAE could greatly increased this ef-fect, whereas defected and stippled pattern showed unsatisfactory effect for the defected and stippledpatterns,2nd LP-TAE could transform them into consolidated and circular pattern, Statistics provedthat the conclution was significant(P< 0.01)
