[Oculomotor nerve paralysis in intracranial aneurysm]. / Porazenie nerwu okoruchowego w tetniakach wewnatrzczaszkowych.

The authors analysed the data in 257 cases treated surgically for intracranial aneurysms. In 8 of these cases evidence of damage to the oculomotor nerve was found, as a result of aneurysms of the posterior communicating artery or the internal carotid near the site where the posterior communicating artery branches off. Six patients had oculomotor nerve paralysis and two had only partial involvement of the nerve. In 4 cases the aneurysm was not ruptured but manifested itself as headache followed by oculomotor damage. The authors stress the necessity of carrying out arteriography in each not clear case of oculomotor damage.
