Cerebral aneurysm historical perspective

Cerebral aneurysm is defined as

• dilations that occur along the weak points along the arterial circulations within brain. [1]

Size:

• small less than 0.5mm

• Medium 6 to 25mm
• Large greater than 25mm

Types:

1. Berry aneurysm
2. Fusiform
3. Mycotic

Prevalence:

The worldwide prevalence of cerebral aneurysms is approximately 3.2%, with a mean age of 50 and an overall 1:1 gender ratio. This ratio changes significantly after age 50, with an increasing female predominance approaching 2:1, thought to be due to decreased circulating estrogen causing a reduction in the collagen content of the vascular tissue.[1]
