Observations on the vascular structure of malignant tumours of the mandible using specimen arteriography
1Department of Radiology, School of Stomatology, Beijing Medical University, People's Republic of China.
Objectives:
To investigate the vascular structure of different malignant tumours of the mandible.
Methods:
Specimen arteriography was performed on seven cases of squamous cell carcinoma of gingiva and four sarcomas.
Results:
Malignant tumours could be divided into two groups: (1) the hypervascular sarcomas in in which the arteries were dilated, distributed evenly and arranged in a bush-like pattern; and (2) hypovascular squamous cell carcinoma with scanty arteries distributed unevenly without dilatation; in some areas, the shape of arteries was irregular and arranged in a network pattern.
Conclusions:
The variation in vascular structure of malignant tumours of the mandible may be related to the outcome of regional chemotherapy.
