Causes and treatments of intracranial aneurysms

Intracranial aneurysm is a disease that occurs on the wall of the arteries inside people's skull. Because the blood vessel tumor here bulges abnormally, it causes subarachnoid hemorrhage in people's brain. Among the many cerebrovascular accidents, intracranial aneurysm is one of the diseases second only to cerebral thrombosis and hypertensive cerebral hemorrhage. Among brain diseases, intracranial aneurysm ranks third. And the disease may recur at any age, so it is necessary for us to know more about intracranial aneurysms.

The timing of surgery for intracranial aneurysm should be determined based on the condition and specific circumstances of the patient. Treatment should be started as early as possible after discovery, and if it is confirmed that surgery is possible, surgery should be performed within one week. If the condition is grade three or above, indicating that the bleeding is severe, there must be cerebral vasospasm and hydrocephalus. At this time, the risk of surgery is relatively high and surgery should be performed after the condition improves after a few days.

Surgical method: craniotomy and clipping of the aneurysm pedicle is the most ideal method and should be the first choice. Because it neither blocks the tumor-bearing artery, but completely eliminates the aneurysm completely. Isolation surgery involves clamping the parent arteries at both ends of the aneurysm and should be used with caution when good collateral supply to the brain cannot be proven. The efficacy of aneurysm wall reinforcement is uncertain and should be used as little as possible. For aneurysms that are clinically unsuitable for surgery but can be reached with catheter technology, interventional treatment with balloon or coil embolization may be an option. Cerebral angiography should be repeated after surgery to confirm whether the aneurysm has disappeared.

After the surgical treatment of aneurysm rupture, the patient is required to rest in bed and minimize adverse sound and light stimulation. It is best to place the patient in the ICU for monitoring. Transcranial Doppler ultrasound examination can monitor changes in cerebral blood flow and help observe the progression of the disease. People with constipation should be given laxatives, normal blood pressure should be maintained, and appropriate sedative treatment should be given. When combined with cerebral vasospasm, vascular protection treatments such as calcium channel blockers can be tried in the early stages. In order to prevent the blood clot at the ruptured aneurysm from dissolving and causing further bleeding, a larger dose of antifibrinolytic agents, such as aminocaproic acid, is used to inhibit the formation of profibrinolytic enzymes. However, it should be used with caution in patients with renal dysfunction as the side effect may be thrombosis.

Intracranial aneurysm is a very difficult disease to treat because the disease occurs in people's brains. Therefore, after suffering from intracranial aneurysm, only by actively diagnosing and treating the intracranial aneurysm and doing a good job of prevention and care of the disease in daily life can we ensure that the intracranial aneurysm is treated and improved as soon as possible.
