Therapeutic arterial embolisation of vascular lesions in the maxillofacial region.

The technique of therapeutic arterial embolisation involves the introduction of a thrombus-inducing material into the lumen of a blood vessel to occlude the vessel and reduce the blood supply to a lesion or to a specific part of the body. It is particularly useful in the maxillofacial region in the management of vascular lesions where marked diminution in blood flow can be achieved. This paper reviews the procedure and the materials for embolisation, and describes four patients for whom it was of considerable assistance.
