Did Cao Cao die of an aneurysm? Many people don't know they have an aneurysm before they have a brain hemorrhage!

"Aneurysm is a common cause of hemorrhagic stroke. Many patients don't even know they have an aneurysm before bleeding." On October 13, at the 8th China-US Health Forum "Stroke Prevention and Treatment", the United States Y Jonathan Zhang, co-chair of the Cerebrovascular Center at Houston Methodist Hospital, said. It is said that Cao Cao in the Three Kingdoms may have an aneurysm, and the sudden death of the aneurysm may be the cause of Cao Cao's death.

According to Y. Jonathan Zhang, after the rupture of the aneurysm, it will cause hemorrhage of the pearl omentum. The bleeding rate in China is much higher than that in Western countries. After bleeding, 10%-15% of patients will die on the spot. 40%-50% of patients die within 30 days. Even if the patient can resume life, nearly 50% of the patient will be disabled, which is a very serious disease. The likelihood of rebleeding within the first 48 hours of bleeding is quite high with dire consequences.

In addition, Y. Jonathan Zhang introduced that stroke is a huge social medical problem. Although hemorrhagic stroke is only a small fraction of strokes, it is only 15%, or about 220,000 patients, in the United States. But in China, stroke, especially cerebral hemorrhage, is a huge cause of disability, morbidity and death.

In Western studies, 2% of the adult population has an unruptured aneurysm, waiting for the day it ruptures to cause a serious embolism. Aneurysm is mainly from the 1970s by Professor Athens with successful surgical treatment of aneurysm and can ensure normal blood vessels.

All in all, hemorrhagic stroke is a deadly disease. There are huge social, economic and public health implications. Endovascular intervention, especially in terms of equipment and technology, has made great progress, and now it has become the main force of treatment!

There are three types of aneurysms: miliary aneurysms, saccular aneurysms, and pseudoaneurysms. Among them, the diameter of miliary aneurysm is the smallest, generally less than 5mm. Saccular aneurysms, on the other hand, are relatively larger and are the main part of neurosurgical management. Generally speaking, the size of a saccular aneurysm is within 1.5cm. If it exceeds this range or even larger than 2.5cm, it is what we call a giant aneurysm.

The impact of aneurysm rupture and bleeding on patients varies in severity, and can be divided into the following five levels according to the severity of the patient's condition.

1. The patient has no obvious symptoms, only mild headache and signs of neck stiffness. 2. The patient has severe headache, accompanied by oculomotor nerve palsy and neck stiffness, but no other neurological symptoms. 3. Mild disturbance of consciousness, restlessness and mild cerebral symptoms. 4. The patient has entered a state of semi-coma, and at the same time has serious conditions such as hemiplegia, early deencephalic rigidity and autonomic disorder. 5. Deep coma, in a state of frequent crisis, and unstable vital signs.

Through the brief introduction above, we have a general understanding of what the three grades of cerebral aneurysm are. Three are the three types of aneurysm classified according to the size of the brain aneurysm, and the fifth grade is based on the severity of the disease after the rupture of the patient's brain aneurysm. Both classification and grading are to better judge the patient's condition, so as to facilitate diagnosis and treatment
