[Therapeutic problems posed by various angiodysplasias]

The clinical and anatomical aspects of the angiodysplasias are multiple and numerous classifications have been proposed. After review of a more simple classification put forward by Natali and Merland based on the contribution of superselective arteriography, consideration is given to a therapeutic approach for each angiodysplasia. Whereas for a long time the only therapeutic alternatives have been between surgery and no surgery, improved arteriographic understanding of these lesions has now permitted improved treatment, by surgery or by embolization or by the combination of the two methods. Finally the fields of the pure arterial dysplasias and the rares phacomatoses are considered, with a therapeutic scheme in each case.
