[Surgical treatment results in intracranial aneurysms]

Therapeutic results are reported in 115 patients operated upon for intracranial aneurysms using the microsurgical technique from Yasargil's approach. Elimination of the aneurysm from the circulation by clipping its pedicle was done in 94 cases (82%), trapping of the afferent artery (12%), in 7 cases (6%) only the wall of the aneurysmatic sac was strengthened by wrapping. A good therapeutic result was obtained in 68 patients (59.1%), satisfactory in 6 (5.2%), poor in 13 (11.3%). The overall mortality was 24.4% (28 cases) but after taking into account 4 patients dying due to extracerebral causes, the mortality caused by complications related to exclusion of the aneurysm from cerebral circulation was 20%. The factors influencing the results of surgical treatment of cerebral aneurysms are discussed in the light of the own material.
