In recent years, with the continuous improvement of people’s living standards and the arrival of the aging population. Cerebrovascular diseases have become the number one killer threatening people’s health. The acute cerebral infarction and cerebral hemorrhage associated with cerebrovascular disease are fierce, with high death and disability rates, and people are afraid to talk about them. However, before the onset of these diseases, cerebrovascular lesions have already occurred, often without obvious clinical symptoms, and after the onset, due to the limited time for treatment, different levels of people’s awareness of these diseases and the existing treatment means vary, so some patients may miss the best time for treatment. With the rapid development of neuroimaging, catheter technology and materials, computers and other sciences, interventional neuroradiology, as one of the fastest growing subspecialties in the field of interventional medicine in recent years, has occupied an increasingly important position in the diagnosis and treatment of cerebrovascular diseases. Interventional neuroradiology is a method of examining and treating cerebral vessels through interventional methods supported by a computerized digital subtraction angiography (DSA) system. The scope of treatment includes abnormalities of blood vessels and related structures in the brain, meninges, maxillofacial region, neck, eyes, ear, nose and throat, spine, and spinal cord. Its treatment techniques include endovascular embolization, intravascular drug perfusion and angioplasty. The biggest advantage is that it avoids the large tissue trauma caused by craniotomy, and it is widely applicable, less traumatic, more effective, and has fewer complications, which has unparalleled advantages of other diagnostic and treatment methods. Selective whole brain angiography is the most basic interventional neuroradiological diagnostic technique. It is performed by puncturing an arterial vessel at the root of the thigh, placing a very thin catheter, reaching the opening of the blood vessels supplying the brain through a certain technique, injecting a contrast agent, and dynamically observing the lesions of the cerebral vessels. Postoperatively, bed rest is required due to the arterial vascular puncture. The only trauma to the patient is the puncture site of about 2 mm at the base of the thigh. In practice, however, many patients are resistant to cerebral angiography, mainly concerned about its safety. For experienced neurointerventional radiologists, it is quite rare for accidents to occur. And as the gold standard for diagnosing cerebrovascular disease, it is very necessary for some patients. A brief overview of the use of therapeutic interventional neuroradiologic procedures in the clinical routine of cerebrovascular disease is presented through the following areas as examples: Intracranial aneurysm In patients with sudden severe headache with subarachnoid hemorrhage, there is a high probability of rupture of the intracranial aneurysm. The disease is very aggressive and has a high mortality rate. Once the bleeding is detected, cerebral angiography should be performed as soon as possible to determine whether it is due to a ruptured aneurysm. The vast majority of aneurysms can now be treated by interventional means, which can prevent the patient from having to undergo craniotomy. The main approach is to place a tiny spring coil inside the intracranial aneurysm to seal the rupture, while keeping the vital vessels open through stents or balloons. With the advancement of material science, methodology and clinical experience, interventional treatment has become the treatment of choice for most intracranial aneurysms. Cerebrovascular malformation In clinical practice, the most common cause of cerebral parenchymal hemorrhage is due to hypertension. However, intracranial or meningeal vascular malformations or fistulas may also lead to cerebral hemorrhage. If the cause of the hemorrhage cannot be determined, cerebral angiography must be performed. If the diagnosis is confirmed, the malformed vascular mass or fistula can be embolized through an interventional approach. This is done by inserting a hair-thin microcatheter through an artery at the root of the thigh into the cerebral vessel and then injecting vascular glue to seal the malformed vessel or fistula for therapeutic purposes. Ischemic cerebrovascular disease Stenosis of the intracranial and extracranial cerebral vessels or detachment of atherosclerotic plaques is the main cause of severe cerebral infarction. Once a lesion is identified a series of accurate evaluations are required. If the stenosis is severe enough or if the risk of plaque detachment is found to be high, stenting should be performed to increase blood flow to the brain and stabilize the localized plaque, with the goal of preventing the occurrence of a severe cerebral infarction. For patients who have already had an acute stroke, time is of the essence. If the patient can reach a neurointerventional center in the shortest possible time, the blocked cerebral vessels can be dissolved or opened by interventional methods. The patient will be able to avoid further disability or reduce the degree of disability. All in all, interventional medicine, as an emerging edge discipline, has gradually developed into an independent discipline. Some hospitals in our province, including ours, have established independent interventional departments including outpatient clinics, operating rooms and wards, as well as specialized interventional neuroradiotherapy teams. With the updating of treatment concepts, the development of new materials and the popularization of new technologies, interventional neuroradiotherapy will certainly be more widely developed and applied for the benefit of the majority of patients.
