    Introduction: There is an unproven consensus that endovascular therapy is safer in the elderly than microsurgical clipping, and considered less invasive, even though General anesthesia is used in both. We consider microsurgical treatment of aneurysms by an experienced team in a high volume center very safe and less invasive than previously thought of the surgery is restricted to the subarachnoid space.

    Methods: Clinical outcome after clipping of unruptured cerebral aneurysms in patients of age 70 and older retrospectively analyzed. All patients were surgically treated by senior author (A.F.K.).

    Results: 83 unrupturd aneurysms were clipped in 68 patients. 10 M/58 F. Average age was 74.06 y (70 -100). 76% patients were 70-75 years-of-age; 19% - 76-80 y; 4% - 81-90 y. One patient was 100 years-of-age. 38.5% aneurysms were <7mm; 42% - 7-12mm; 17% were 13<25mm and 2.4% were >25mm. 87% aneurysms were located in anterior circulation with average size 9.19 +/- 5.65mm (median 9.5mm) and 13%- in posterior circulation with average size of aneurysm 10.04 +/- 3.39mm (median -10.5mm). Mortality rate 1.4 % (1 pt with basilar trunk 15mm aneurysm had acute cardiovascular collapse). Median stay in hospital – 5 days. MRS-0 at discharge - 46% pts; MRS -1 in 28% pts; MRS -2 – in 7% pts. MRS 3-4 in 16% pts. On f-up 6mo-1 y 95% had MRS 0-1. Recurrence rate 0%. Patient of 100 years of age was discharged at home on 4th day after clipping of 15mm Acom aneurysm with MRS- 0.

    Conclusions: Microsurgical treatment of aneurysms in the elderly performed by an experienced team in a high volume center has an outcome compatible if not better than endovascular therapy, and should not be considered more invasive and more risky than the later.

    Patient Care: Definite elimination of the aneurysm from the circulation with reduced length of stay and post-procedural complication and exposure to radiation.

    Learning Objectives: 1. The microsurgical outcome of treatment of unruptured aneurysms in a high volume center in the elderly 2. Safety and durability of the microsurgical treatment of unruptured aneurysms in a high volume center in the elderly 3. The clinical aspects of unruptured aneurysms in the elderly
