Objective:
Pseudoaneurysm in siphon section of internal carotid artery (ICA) caused by craniocerebral trauma was diagnosed and totally embolized by applying digital subtraction angiography (DSA) technique, with satisfactory results. The clinical application of this technique was discussed.
Methods:
The patients suffered from craniocerebral trauma with serious epistaxis were managed in our hospital by DSA. The patients with pseudoaneurysm in ICA were chosen from them. The circular function of Willis circulus in these patients were checked. If it was good, the ICA was totally embolised.
Results:
Among 32 patients suffered from craniocerebral trauma with serious epistaxis, 6 patients were definitely diagnosed by DSA to have pseudoaneurysm. The embolism was performed in 5 of them. Among these 5 patients, 4 cured, and 1 died. The patient who could not be embolized also died.
Conclusion:
The pseudoaneurysm definitely diagnosed by DSA can be treated by embolizing siphon section of internal carotid artery completely, after checking the compensatory function of side branches in Willis circulus.
