To discuss the safety and effectiveness of the early endovascular treatment for ruptured intracranial aneurysms.

Forty cases, who were diagnosed with aneurysmal subarachnoid hemorrhage by CT and DSA in Zhangjiagang Aoyang Hospital, were analysed retrospectively. All the patients were evaluated with GCS and GOS.

Forty-four intracranial aneurysms were found in 40 patients. The volume embolization ratio (VER) were used for assessing the effectiveness of embolization. A hundred percent embolization were found in 27 aneurysms (61.4%), 95% embolization in 12 aneurysms (27.2%), 90% embolization in 4 aneurysms (9%) and 80% embolization in 1 aneurysm (2%). No re-rupture happened. Twelve patients (30%) suffered cerebral vacular spasm. And delayed hydrocephalus occurred in 2 patients (5%). Thirty-five patients (79.5%) recovered well. Only 1 patient died. All the patients have been followed up for 3 months to 3 years.

Early endovascular treatment for ruptured intracranial aneurysms is safe and effective. The incidence of aneurysm re-rupture can be reduced. Hemorrhagic CSF drainage can reduce the occurrence of cerebral vacular spasm and delayed hydrocephalus and good for the patient’s recovering.
