Abstract
Among the malignant tumors except leukemia, the incidence of abdominal tumors is the highest in solid tumors of children.
Neuroblastoma, Wilms' tumor, and hepatoblastoma are most common malignant abdominal tumors in children.
Angiography was applied for each case of them, and it was proved that this was the useful method both in the diagnosis and in the treatment.
Abdominal angiography does not only enable us to make the pathognomonic diagnosis, but also contributes to the decision of operative indication and to it's practice.
Besides, the finding of angiography is applied for setting-up of optimal treatment for radiotherapy.
In addition to aortography, the selective angiography may offer more accurate information, and at the time of the procedure, injection of anticancer drug through the catheter to the nourishing vessel of the tumor may prevent the tumor cells from metastasizing to the other organs.
And more beneficial antitumor effect might be expected by means of regional high concentration of the drug, and the side effects by the chemotherapeutic agents could be reduced.
Usually we are used to administrate adriamycin or daunomycin in neuroblastoma, and actinomycin-D in Wilms' tumor, because these drugs are rapidly adsorbed and fixed to regional tissue, especially to tumourous tissue.
Generally, in hepatoma chemotherapeutic agents are not so effective, but we administrate vincristine, for we have effective cases treated with vincristine through arterial infusion.
