Diagnosis and treatment of intracranial aneurysms

Objective” To study the diagnostic procedures, surgical techniques, and operative time in the treatment of patients with intracranial aneurysms. [WT5”HZ]Methods[WT5”BZ] The data of 410 patients who had been operated upon for intracranial aneurysms were reviewed retrospectively. Among these patients, 172 received clipping under direct vision, and the remaining 238 were treated by endovascular embolization. ResultsExcellent results were seen in 298 patients, good (mild disabilities) in 85, and poor (moderate and serious disabilities) in 12. 14 patients survived in a vegetative state and 1 died. Conclusions CT, MRI and MRA provide important information for the diagnosis of intracranial aneurysms, but DSA is decisive. Aneurysm may be found by TCD. Microsurgical clipping under direct vision and endovascular embolization are the major therapeutic methods. Emergentcy microsurgery is applicable to patients with hemorrhage due to the rapture of intracranial aneurysm.
