Abstract: 【Objective】 To observe the effect of injection of the mixture of radiocolloid chromium phosphate-32 and dexamethasone in skin cavernous angioma or and mixed angioma in younger children. 【Methods】 778 angiomas of 638 patients with skin cavernous angioma or and mixed angioma were received one to three course treatment of intra-angioma injection with this mixture

the average injection dosage was (673 ± 275)kBq/cm2

and the mixed angioma also received therapy with phosphate-32applicator simultaneously. The effect was evaluated according to the size of angioma and the patient＇s age. 【Results】①778 angiomas were received 1.59 courses treatment. According to the angioma area

the one course

two-course total and three-course total cure rate were 64.27%

89.08%

and 96.14%

respectively. The total effective rate were 91.90%

97.17%

and 98.07%

respectively. The less size of angioma

the better treatment effect

there was a significance(P < 0.001). ② According to the patient＇s age

the one course

two-course total and three-course total cure rate in 638 patients were 62.70%

88.25% and 94.67%

respectively. The total effective rates were 89.66%

96.08% and 98.12%; The younger received treatment

the better therapeutic effect

there was a significance (P < 0.001). 【Conclusion】 It is a simple

safe

and greatly effective therapy for patients with skin cavernous angioma or and mixed angioma with injection of the mixture of radiocolloid chromium phosphate and dexamethasone

and worth for clinical application.
