The methods of cerebrovascular interventional therapy include endovascular arterial thrombolysis, arterial angioplasty, cerebrovascular embolization and so on. 1. Endovascular arterial thrombolysis: the main indication for this treatment is acute ischemic cerebrovascular disease, usually performed within 6 hours of the onset of the disease, can be given directly in the artery to open the blood vessels, improve the recanalization rate of the occluded blood vessels, and is suitable for patients who are not suitable for intravenous thrombolysis. 2. Arterial angioplasty: this treatment is also a minimally invasive surgical treatment emerging in the past 10 years, which mainly puts stents into the cerebral blood vessels to open up the narrowed and hardened cerebral arteries to improve cerebral blood supply. 3. Cerebrovascular embolization: this treatment method mainly involves injecting embolic substances into the diseased cerebral blood vessels, and commonly used embolic agents include iodized oil, etc. to make the blood vessels occluded and interrupt the blood supply, so as to achieve the purpose of treating cerebral hemorrhage. Different cerebrovascular interventional therapies are used to treat different brain diseases, and their indications should be strictly grasped and carried out under the guidance of doctors.
