Intracranial aneurysm is an abnormal bulge that occurs in the wall of intracranial arteries, which is the primary cause of subarachnoid hemorrhage, and ranks third in cerebrovascular accidents after cerebral thrombosis and hypertensive cerebral hemorrhage, but this kind of patients have high disability and mortality rates. Since the first half of the year, the Department of Neurosurgery, in the midst of a steady increase in the number of patients with cerebral aneurysms, has successfully performed intracranial aneurysm removal for a patient with multiple intracranial aneurysms, who was discharged from the hospital and resumed his normal life after careful treatment and care by the medical staff. Lin Moumou from Luoyuan County in her fifties is an elderly female patient with 2 aneurysms in one side of the cerebral vessels. She had a severe headache after bleeding and went to our hospital for CTA and DSA examination. The surgical risk of multiple intracerebral aneurysms is significantly higher than that of general aneurysm surgery, and is especially prone to rupture and hemorrhage during the operation, and once rupture and hemorrhage occurs during the operation, the chances of various after-effects are much higher. With the full cooperation of anesthesiology department, the cerebrovascular disease treatment team headed by Dr. Liu Shengze, the chief physician of neurosurgery department, made all the sufficient preoperative preparations, designed a smaller incision suitable for the patient during the operation, opened the skull, and then, by virtue of the many years of aneurysm surgical experience, the pair of excellent hands kept changing the hands of all kinds of microsurgical instruments, and skillfully separated the aneurysms along the anatomical gaps of the brain tissues and cerebral blood vessels in the brain, one step at a time. The aneurysm is surrounded by the aneurysm. Separation of aneurysm peripheral tissues is the last step before aneurysm clamping, and it is the necessary journey before the dismantling of “time bomb” in the brain, and it is also the easiest time for aneurysm rupture and hemorrhage, and if you are not careful, the aneurysm will rupture and hemorrhage. The test is not only the operator’s ability to deal with emergencies immediately during the operation, but also the operator’s psychological state, which requires “careful and meticulous” surgical skills and a good mindset of “not being shocked by changes”. After intense and meticulous separation, the aneurysm was finally successfully exposed and clamped, and the “time bomb” in the brain was successfully “defused”, avoiding the serious complications that might be caused by re-rupture of the aneurysm, and then the second aneurysm was also successfully clamped. According to the neurosurgeon’s introduction: “Cerebral aneurysm is not a real tumor, it is due to the arteries supplying the brain in the process of growth and development of anomalies, the long-term impact of the blood flow, the local blood vessel wall thinning, and gradually puffed out and produced from the appearance of a ‘tumor’. It is a ‘bomb’ hidden in the brain, usually no sign, once rupture can lead to serious intracranial hemorrhage, instant life-threatening, but usually basically no warning symptoms, it is because it is too hidden, people do not pay enough attention to the ordinary headache symptoms, so that part of the patient lost the opportunity to treat. Neurosurgery experts remind everyone that seasonal change is the most common period of cerebral aneurysm rupture, and the chance of cerebral aneurysm rupture increases. Early detection of cerebral aneurysm, early treatment is the key, especially for people with family history of the disease, high blood pressure and other high-risk groups, they should be screened, and do not wait until the rupture of the aneurysm to be treated again, so as not to cause a danger to life.
