Neurointerventional technology is the treatment of cerebrospinal vascular lesions using a non-invasive approach with the help of DSA and under X-ray fluoroscopy. Interventional procedures are less invasive, have faster recovery and fewer complications, and are now more and more accepted. The common conditions treated by intervention are divided into two categories: hemorrhagic diseases: intracranial aneurysms, cerebral arteriovenous malformations, carotid cavernous sinus fistula, dural arteriovenous fistula, various types of spinal vascular malformations, congenital cerebrovascular disease in children (such as aneurysmal dilatation of large cerebral veins), and intractable rhinorrhea. Ischemic cerebrovascular disease: stenting treatment of carotid artery, middle cerebral artery, vertebral basilar artery stenosis, cerebral venous sinus thrombosis, thrombolytic treatment of acute cerebral infarction, etc. Common problems: At present, most patients are still unfamiliar with neurointerventional surgery, but in fact, neurointerventional surgery has been carried out maturely for more than 20 years, and neurointerventional surgery in China is basically carried out in parallel with the international level, and is now comparable to or even slightly higher than the international level. The mortality rate + complications of neurointerventional surgery is about 5% in international bulk case statistics, and the cases in our hospital are far below this level. In addition, the majority of surgical materials are covered by medical insurance, and the average patient’s out-of-pocket cost is 30,000-40,000 for aneurysms and less than 20,000 yuan for stents in one part alone. Knowledge: Most intracranial aneurysms are not detected by conventional CT or MRI examinations before they rupture and bleed, and are asymptomatic, at which point head CTA examinations can be diagnosed in most patients. Ruptured aneurysms manifest as subarachnoid hemorrhage or ventricular hemorrhage and are most likely to occur between the ages of 30-60. Spontaneous subarachnoid hemorrhage should be treated as soon as it is detected. Carotid cavernous sinus fistula is a condition that is often misdiagnosed based on the typical symptoms of lid conjunctival erythema and ectropion, protrusion of the eyeball, fixation, and intracranial murmur. Most patients first go to the ophthalmology department and even take many detours. Neurointerventional surgery is the best option to treat this disease. Cerebrovascular stenosis is divided into anterior circulation and posterior circulation, and most of the anterior circulation ischemia is manifested as: transient contralateral limb weakness, numbness, slurred speech, and blackness in one eye. Most of the ischemia in the posterior circulation is manifested as vertigo, transient dysarthria, dysphagia, sudden collapse, darkness in one or both eyes, and numbness and weakness of the limbs. At this time, examination and stenting treatment should be performed, and if the best time is missed, it may develop into permanent cerebral infarction and leave serious sequelae. Early cerebral infarction can be treated with arterial thrombolysis within 6 hours, and the time window of 6 hours is very important, and most patients have missed this time window at present. Therefore, it is essential to go to a qualified medical institution for treatment once the attack has occurred. Cerebral venous sinus thrombosis occurs mostly in women during pregnancy and presents with severe headache, epilepsy, impaired consciousness, coma, increased intracranial pressure, cerebral edema, and cerebral hemorrhage. The combination of interventional opening of occluded venous sinus and thrombolysis can save the lives of most patients. Specialized features: Our neurointerventional specialty group is a relatively independent specialty group under the unified leadership of the Department of Neurosurgery, and each surgical case is discussed by all the experts and professors before making the best surgical treatment plan. In addition to having carried out various routine interventional procedures for cerebrospinal vascular diseases, our hospital is the first hospital in China to introduce a multi-functional operating room, i.e., a cerebral angiography machine is installed in the operating room, making it possible to successfully complete some procedures that require a combination of intervention and open surgery, which is unique in Tianjin. In addition, as the largest general hospital in Tianjin, some patients with multi-organ comorbidities or children and gynecology can receive timely and appropriate treatment.
