Dear Sir, I am a neurosurgeon of Beijing Tiantan Hospital. I am interested in etiology of intracranial aneurysm,I knew that many of aneurysm is congenital, and have a genetic trend. And in some aneurysm family, their serum lipoprotein(a) level is higher. The attack of aneurysm is also associated with human's food.In weatern country and Japan, the incident rate of aneurysm is high,but in China and other Eastern country, it was low. Now our research group want to do some study of it.Would you like to give me some useful information just like article, abstract or anything else.
