Abstract:
Sixteen ruptured aneurysms in 16 patients considered endovascular embolizations were examined. The findings of axial source images (axial images) and reconstructed three-dimensional CT angiography (3D-CTA) of helical CT were compared to those of rotational digital subtraction angiography (DSA). The aneurysmal neck and arterial branches adjacent to the neck were closely investigated. In seven out of 16 cases (43.8%), information provided by axial images and/or 3D-CTA was more useful than that of rotational DSA in evaluating the aneurysmal neck and arterial branches. Helical CT can provide valuable information on ruptured aneurysms that cannot be obtained by rotational DSA in some patients. This technique is useful to obtain anatomical information about aneurysms and to select the best therapeutic method.
