Microsurgical treatment for multiple intracranial anterior circulation aneurysms

Objective To summarize our experiences with a clipping microsurgical treatment and prognoses of 146 cases with multiple intracranial anterior circulation aneurysms.Methods These aneurysms were divided into responsible and non -responsible aneurysms.Responsible aneurysms were given priority,non- responsible aneurysms were given the selective treatment. Results Among 146 patients,a postoperative Glasgow outcome score (GOS) of grade 5 was found in 136 cases,grade 4 in 6 cases,grade 3 in 1 case,and death ( grade 1 ) occurred in 3 cases.At 3 - and 6 - month postsurgical follow - ups,computed tomography angiography (CTA) revealed completed clipping of all responsible aneurysms and no changes in the non - responsible in 143 cases.Apart from the 3 cases in which death occurred,we followed up a total of 128 cases between 5 and 10 years after surgery.Hemorrhage occurred in only one case of non -responsible aneurysms that had not received treatment,6 years after surgery,and a good prognosis was achieved after retreatment.Conclusion Satisfactory prognoses were achieved in the selective treatment of multiple intracranial anterior circulation aneurysms.\r\n\r\nKey words: \r\nIntracranial aneurysms; multiple; Microsurgery; Prognosis
