[Contribution of superselective arteriography and embolization in maxillofacial surgery. Apropos of 2 cases]

After describing the technique of embolisation and its therapeutic indications,the authors present two cases of different indications:--embolisation as the sole treatment,--pre-operative embolisation of a haemorrhagec tumour. These two cases illustrate two applications of the technique of embolisation:--Medical therapeutic value: making possible the reduction or stabilisation of the size of a vascular tumour difficult to excise surgically, in addition to eliminating the complications (haemorrhage, local trophic disturbance, pain);--Surgical interest: elective lesional embolisation such as is carried out at present greatly facilitates the surgical procedure in operations which may be associated with severe bleeding. Problems of healing are avoided. The procedure is carried out at the same time as selective arteriography. When in the hands of a skilled team, scarcely any risk is involved.
