Clinical Comparative Study of Cerebral Aneurysms in Young and Old Aged Patients

ABSTRACT

Among the four-hundred patients with cerebral aneurysms confirmed by cerebral angiography, we divided them into two age groups, one with ages 39 years or younger(young-aged group 51 patients, 12.8%), and another with ages 65 years or older(old aged group 45 patients, 11.3%). A comparison was undertaken in regard to clinical characteristics and overall outcome in two groups. In young-aged group, the female-to-male ratio was 2.2 1 whereas, women was predominant by five times more in old aged group. Anterior communicating artery aneurysm was the most common site(43.1%) in young-aged group, unlike to old aged group where posterior communicating artery was the most common site(33.3%). The most common symptom was headache in both groups, and the hypertension was more frequent in young-aged group(45.5%) than old-aged group(33.3%). Surgery was performed in 43 patients(84%) in younger group, and 37 patients(82.2%) in elderly group. Young-aged group showed more favorable outcome(91%) than old-aged group(70%).
