The process of endovascular treatment of cerebral aneurysms requires intensive use of 3D rotational angiography in planning and monitoring the entire process. 3D RA allows unlimited manipulation of model blood vessels and defining the morphology of the aneurysm without using radiation. The purpose of the study was to compare the results of the analysis of residue or recurrence of the aneurysm after endovascular treatment using 3D RA and 2D digital subtraction. Method. In 68 patients with 76 cerebral aneurysms, we made regular controls using both techniques, 2D DSA and 3D RA. Residual and recurrent aneurysms are classified into five stages, and the pictures taken by both modalities are compared. Results. 2D DSA detected the residual and recurrent aneurysm in 53.70% of cases (29/54 aneurysms), and 3D RA in 66.67% (36/54 aneurysms). In nine cases in 2D DSA did not detected residues of which was discovered in 3D RA, and 3 cases of 2D DSA reveals little short neck aneurysm, which is on the 3D RA, in fact, a small aneurysm. In five cases from the use of 3D RA reduced the level of classification aneurysm.

Conclusion: 3D RA reveals more residues aneurysms.

Keywords: 3D RA, 2D DSA, endovascular treatment of cerebral aneurysms.
