Cerebrovascular diseases mainly include cerebral infarction, cerebral hemorrhage, subarachnoid hemorrhage, cerebral aneurysm, cerebrovascular malformation, etc. Among them, stroke has become one of the three major diseases causing human death worldwide. The treatment of cerebrovascular disease is mainly based on surgery. Over the years, we have continuously improved our surgical methods and formed a set of “minimally invasive” treatment methods. For example, in patients with cerebral hemorrhage, the removal of the hematoma can be achieved through a 5 mm micro-hole using stereotactic techniques and hard channel puncture. In recent years, endovascular treatment (interventional therapy) has been developed, which is a minimally invasive treatment method characterized by no incision, little trauma, and fast recovery after surgery. The main diseases treated are: 1. Arterial thrombolytic therapy for cerebral infarction can dissolve the thrombus, restore the blood supply to the infarcted area, improve the patient’s hemiplegia and other symptoms to the maximum extent, and reduce the disability and mortality rate. However, the treatment must be timely. Embolization treatment of cerebral aneurysm can be applied to embolize the aneurysm with spring ring, which makes it possible to treat cerebral aneurysm without surgery. Embolization treatment of cerebral arteriovenous malformation, through interventional means to apply adhesive to close the malformed vessels, provides a treatment route for many patients who cannot be operated. 4.Carotid artery stent treatment, for patients with carotid stenosis, stents can be placed at the stenosis to dilate the carotid artery, improve cerebral blood supply, and greatly reduce the incidence of cerebral infarction, etc. 5.Embolization of brain tumors, especially for tumors with rich blood supply, can greatly reduce intraoperative bleeding and make the surgery safer.
