[The risk of ligation of the external carotid in the treatment of cervico-facial angiodysplasia. A plea for this technique to be abandoned, and current radiosurgical solutions; based upon 13 cases of ligation amongst 200 angiomas explored (author's transl)].

: After describing the different collateral sytems between the various cervicocephalic arteries, the authors indicate the consequences of ligation of the external carotid. This ligation proves to totally ineffective for distal vascular lesions and severely compromises the possibilities of later treatment.
