[Treatment of lingual angiocavernoma by selective arteriocatheterization with urea injection].

Selective arteriocatheterization with urea injection was administered to 36 cases of lingual angiocavernoma. There were 20 males and 16 females, ranging in age from 6 to 18 years with an average of 12 years. Two to five mililiters of 40% urea were injected once a day for 10-15 days as a course of treatment, 29 cases (80.6%) were cured in one course of treatment. The other 7 cases (19.4%) were cured in the 2nd course of treatment. The results suggest that selective arteriocatheterization with urea injection is a safe, convenient and effective technique in the treatment of ingual angiocavernoma.
