Difference in nature of ruptured and unruptured cerebral aneurysms

Lancet. 2000 Jan 15;355(9199):203. doi: 10.1016/S0140-6736(99)03881-7.


Although small aneurysms have an extremely low probability of rupture, most aneurysms that rupture are found to be less than 10 mm in diameter. Histological study of aneurysms and epidemiological analysis of subarachnoid haemorrhage revealed that ruptured and unruptured aneurysms are of a different nature.
