[Cerebral aneurysms and current methods of treatment]

The authors discuss briefly aneurysms cerebral arteries. In the light of the pertinent literature the hypotheses of their development are reviewed. These aneurysms are probably lesions acquired by individuals with special predispositions, acquired or inborn. The problems of aneurysm diagnosis are reviewed and the methods are discussed of their management, both surgical and intravascular (embolization). Both methods are tentatively compared. In certain cases each method may be an excellent alternative for the other, and in other cases they are mutually complementary extending thus the range of therapeutic possibilities.
