[Digital subtraction angiography on glomus jugularis tumors].
OBJECTIVE
To analysis the effectiveness of preoperative digital subtraction angiography (DSA) on glomus jugularis tumors.


METHODS
A retrospective study of 14 cases of glomus jugularis tumors which received preoperative DSA was carried out. Among them, 10 cases were accepted balloon occlusion test and selective embolization of supplied vessels.


RESULTS
Hypervascular changes was found in all 14 cases and compression of internal carotid artery was found in 5 cases. Ascending pharyngeal artery was the main supplied vessel. Balloon occlusion test was applied in 10 cases, 2 were intolerable and 8 were passed occlusion test. Ten cases were accepted embolizations and tumor blood supply was conspicuous decreased. Neurovascular complications did not occurred after DSA but postoperatively in 2 cases. Intraoperative bleeding was less in embolization patients than that of without embolization.


CONCLUSIONS
Preoperative DSA association with balloon occlusion test and embolizations might be a safe option on surgery of glomus jugularis tumors.
