[Vascular structure of malignant tumours of the mandible shown by specimen arteriography].

OBJECTIVE
To investigate the vascular structure of different kinds of malignant tumours of the mandible.


METHODS
Specimen arteriography was performed on 11 cases of malignant tumours of the mandible.


RESULTS
Malignant tumours could be divided into two groups: 1. the hypervascular tumours, the arteries are dilated, distributed evenly and arranged in a bush-like pattern. 2. hypovascular tumours, the scanty arteries are distributed unevenly without dilation, in some areas, the shape of arteries are irregular and arranged in a network pattern.


CONCLUSION
Variation in vascular structure of malignant tumours in the mandible may be related to the outcome of regional chemotherapy.
