The review provides information on the possibilities and significance of computed tomography (CT) angiography as a method of postoperative control of cerebral aneurysms after treatment (surgical clipping or endovascular embolization). The comparison of the diagnostic value of CT and cerebral angiography as a routine method of postoperative control is shown. The possibilities of improving the methods of scanning and post-processing in the framework of CT angiography are described for better visualization of the completeness of aneurysm shutdown, as well as minimizing artifacts from surgical clips and coils.
