Objective:To evaluate the safety

technical success rate

and effectiveness of transcatheter superselective arterial chemoembolization(TACE)for unresectable lung cancer and the metastases tumor with rich blood feeding in lung.Methods:Using Japan Shimadzu 1250Ma CCD DSA X machine

4F RH or 4F YASHIRO catheter and 3F SP microcatheter were employed in superselective chemoembolization for feeding artery of lung cancer and the metastases tumor with rich blood feeding in lung with lipiodol and 2～3 species chemodrug.The period of repetitive treatment was 4～6weeks.After treatment

the change of the symptoms

images of neoplasm and the survival rates were observed.Results:Transcatheterization and embolization were successfully completed in 88 out of 90 cases.Technical success rate was 97.8% without spinal damage occuring.After 2～3 time treatment

the symptoms of the patients obviously improved in 87cases(96.7%);neoplasm notable shrank in 82 cases(91.1%)

partly shrank in 5 cases(6%)

not shrinking in 3 cases(3.3%).The survival rate respectively at 6 months

12 months

24 months

36 months were 98.8%(89/90)

93.3%(84/90)

83.3%(75/90)and 53.3%(48/90).Conclusions:The technical success rate at Superselective transcatheter arterial chemoembolization for feeding artery of the neoplasm that rich blood fed in lung is high.Complications rate is lower.Its effectiveness is more notable than bronchial artery chemodrug infusion.
