Abstract:
Objective To evaluate the value of three dimensional reconstruction images of rotational DSA on measuring aneurysmal necks and make a comparison with traditional DSA so as to provide more abundant and accurate informations for the enbolization of aneurysm. Methods A comparison was made between the measurement of aneurismal necks from 14 cases with traditional DSA examination and a measurement made on three dimensional reconstruction images of the same patient. Results There was a difference shown in the measurment of the aneurysmal necks between three dimensional reconstruction images of rotational DSA and those of traditional DSA, outcoming with more angles and data on three dimensional reconstruction images. Conclusions There are more angles of aneurysmal neck can be shown on rotational 3D DSA especially for the demonstration of the largest aneurysmal neck with a directional value for the intervention.
